C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 General Information Inspection - Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the carton or crating of each unit, and inspect each unit for damage. Assure the carrier makes proper notation of any shortages or damage on all copies of the freight bill and completes a common carrier inspection report. Concealed damage not discovered during unloading must be reported to the carrier within 15 days of receipt of shipment. If not filed within 15 days, the freight company can deny the claim without recourse. Note: It is the responsibility of the purchaser to file all necessary claims with the carrier. Notify the ClimateMaster Traffic Department of all damage within fifteen (15) days of shipment. Storage - Equipment should be stored in its original packaging in a clean, dry area. Store units in an upright position at all times. Do not stack. Unit Protection - Cover units on the job site with either shipping packaging, vinyl film, or an equivalent protective covering. Cap the open ends of pipes stored on the job site. In areas where painting, plastering, and/or spraying has not been completed, all due precautions must be taken to avoid physical damage to the units and contamination by foreign material. Physical damage and contamination may prevent proper start-up and may result in costly equipment clean-up. Examine all pipes, fittings, and valves before installing any of the system components. Remove any dirt or trash found in or on these components. Pre-Installation - Installation, Operation, and Maintenance instructions are provided with each unit.. The installation site chosen should include adequate service clearance around the unit. Before unit startup, read all manuals and become familiar with the unit and its operation. Thoroughly check the system before operation. Prepare units for installation as follows: 1. Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped. 2. Keep the cabinet covered with the shipping packaging until installation is complete and all plastering, painting, etc. is finished. 3. Verify refrigerant tubing is free of kinks or dents and that it does not touch other unit components. 4. Do not apply power to compressors until startup. Verify isolation switches (at bottom of low voltage section) are off. 5. Verify I/O Flex 6126 board has jumper set to 5 Vac. See Wire Diagram. CAUTION! CAUTION! All three phase scroll compressors must have direction of rotation verified at start-up. Verification is achieved by checking compressor Amp draw. Amp draw will be substantially lower compared to nameplate values. Additionally, reverse rotation results in an elevated sound level compared to correct rotation. Reverse rotation will result in compressor internal overload trip within several minutes. Verify compressor type before proceeding. CAUTION! CAUTION! DO NOT store or install units in corrosive environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.). Corrosive conditions and high temperature or humidity can significantly reduce performance, reliability, and service life. Always move and store units in an upright position. Tilting units on their sides may cause equipment damage. CAUTION! CAUTION! CUT HAZARD - Failure to follow this caution may result in personal injury. Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing, safety glasses and gloves when handling parts and servicing heat pumps. Handling - Carefully remove the unit’s packaging. The steel base cut-outs provide maneuverability by forklift or pallet jack into its final position (See Rigging and Lifting Procedures). Rigging and Lifting - Each unit should be lifted by using a pallet jack or fork lift in base slots. If it is necessary to utilize a crane for rigging or lifting, use lifting straps and spreader bars. c l i m a t e m a s t e r. c o m 5 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Unit Physical Data Model TMW360 Compressor (qty) Scroll (2) Compressor Oil Type Factory Charge HFC-410A (lbs) [kg] / circuit TMW600 TMW 840 Scroll (2) Scroll (2) ALL REVA REVB ALL POE POE PVE PVE 15 [6.8] 27.5 [12.5] 33.8 [15.4] Indoor / Load Water connection sizes FPT (in) 2 2-1/2 2-1/2 Outdoor / Source Water connection size FPT (in) 2 2-1/2 2-1/2 Weight - Operating (lbs) [kg] 1400 [635] 2055 [932] 2305 [1042] Weight - Shipping (lbs) [kg] 1325 [601] 1925 [873] 2175 [983] 4.7 [17.8] 8.3 [31.4] 9.5 [36] 4.4 [16.7] 7.3 [27.6] 8.5 [32.2] Water Volume (Source) Gallons [Liters] Water Volume (Load) Gallons [Liters] Insulated Source and Load Water Coils standard.

Locate the unit in an INDOOR dry, conditioned air (see Operational Limits Table - 9) area that allows enough space for service personnel to remove access panels and to perform typical maintenance or repairs in the future. The installation of water-source heat pump units and all associated components, parts and accessories which make up the installation must be in accordance with the regulations of ALL authorities having jurisdiction and MUST conform to all applicable codes. It is the responsibility of the Installing Contractor to determine and comply with ALL applicable codes and regulations. ClimateMaster recommends locking down the TMW to a concrete base or to three 4” field supplied base rails that can support the unit weight. Base pan has 6 bolt holes for securing to base or rail. Recommended service clearances are 36” (91cm) at front, 30” (76cm) at rear, and 18” (46cm) above. Optional service clearances 24” (61cm) each side. Provide sufficient room to make water and electrical connections. Access panel screws are for shipping and may be removed prior to setting the unit. These units are not approved for outdoor installation and, therefore, must be installed inside the structure being conditioned. Note: Do not apply power to compressors until startup. Verify isolation switches (at bottom of low voltage section) are off. The Load side should have a minimum capacity of 6 gallons per ton of cooling ouput capacity to prevent compressor short cycling. Note: If springs or vibration isolation pads are used, size and weight distribution must be determined by a qualified structural engineer. 8 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Piping Installation Installation of Supply and Return Piping for Load and Source Follow these piping guidelines. 1. Install a drain valve at the base of each supply and return riser to facilitate system flushing. 2. Install shut-off / balancing valves and unions at each unit to permit unit removal and for servicing. 3. Install shut off valves to isolate strainers. 4. Install 60 mesh strainers on unit inlet for both Source and Load. Recommend basket strainer on Source. 5. Select the proper hose length to allow slack between connection points. Hoses may vary in length by +2% to -4% under pressure. 6. Exceeding the minimum bend radius may cause the hose to collapse which reduces water flow rate. Install an angle adapter to avoid sharp bends in the hose when the radius falls below the required minimum and causes a slight kink. 7. Install (4) petes ports, install on both Source and Load inlets and outlets. 8. Both Load and Source must adhere to Water Quality Standards. See Table 5. Copy of water test to be sent to ClimateMaster technical service department. Optional pressure-rated hose assemblies designed specifically for use with ClimateMaster units are available. Similar hoses can be obtained from alternate suppliers. Supply and return hoses are fitted with swivel-joint fittings at one end to prevent kinking during installation. Refer to Figure 1 for an illustration of a Supply/Return Hose Kit. Male adapters secure hose assemblies to the unit. Install hose assemblies properly and check them regularly to avoid system failure and reduced service life. WARNING! WARNING! Polyolester Oil, commonly known as POE oil, or Polyvinylether, commonly known as PVE oil, are synthetic oils used in many refrigeration systems including those with HFC-410A refrigerant. POE, or PVE oil, if it ever comes in contact with PVC or CPVS piping, may cause failure of the PVC/CPVC. PVC/CPVC piping should never be used as supply or return water piping with water source heat pump products containing HFC-410A as system failures and property damage may result. CAUTION! CAUTION! Corrosive system water requires corrosion resistant fittings and hoses and possibly water treatment. WARNING! WARNING! Piping must comply with all applicable codes. Figure 1: Supply/Return Hose Kit WARNING! Rib Crimped Swivel Brass Fitting Brass Fitting WARNING! Do not bend or kink supply lines or hoses. Insulation is not required on loop water piping except where the piping runs through unheated areas or outside the building or when the loop water temperature is below the minimum expected dew point of the pipe ambient temperature. Insulation is required if loop water temperature drops below the dew point. Length (2 ft [0.6m] Length Standard) MPT MPT (Typical Both Hoses) Figure 2: Connection Locations Pipe joint compound is not necessary when Teflon threaded tape is pre-applied to hose assemblies or when flared-end connections are used. If pipe joint compound is preferred, use compound only in small amounts on the pipe threads of the fitting adapters. Prevent sealant from reaching the flared surfaces of the joint. Source connections Load connections Field-supplied power disconnect Field-supplied flex-conduit Note: When antifreeze is used in the loop, assure that any Teflon® tape or pipe joint compound used is compatible. Maximum allowable torque for brass fittings is 30 ft-lbs [41 N-m]. If a torque wrench is not available, tighten fingertight plus one quarter turn. Tighten steel fittings as necessary. c l i m a t e m a s t e r. c o m 9 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Load Plumbing Installation TMW Unit Load Plumbing - The applications are too varied to describe in this document. However, some basic guidelines will be presented. Much of the discussions on water loop applications would be valid for the load plumbing discussion as well. All plumbing must conform to local codes with the following considerations: Wide temperature variation applications such as heating/cooling coils: • Employ piping materials that are rated for the maximum temperature and pressure combination. This excludes PVC for most heating applications. • Ensure that load water flow in high temperature heating applications is at least 3 gpm per ton [3.9 l/m per kW] to improve performance and reduce nuisance high pressure faults. • DO NOT employ plastic to metal threaded joints • Utilize a pressure tank and air separator vent system to equalize pressure and remove air. Potable Water Applications: • Load exchanger should be isolated with secondary heat exchanger. • Ensure load water flow in high temperature heating applications is at least 3 gpm per ton to improve performance and reduce nuissance to high pressure faults. Note: The manufacturer strongly recommends all piping connections, both internal and external to the unit, be pressure tested by an appropriate method prior to any finishing of the interior space or before access to all connections is limited. Test pressure may not exceed the maximum allowable pressure for the unit and all components within the water system. The manufacturer will not be responsible or liable for damages from water leaks due to inadequate or lack of a pressurized leak test, or damages caused by exceeding the maximum pressure rating during installation. Swimming Pool Hot Tub Applications: • Load exchanger should be isolated with secondary heat exchanger constructed of anti-corrosion material for chlorine/bromine fluid applications.

TMW360-840 units can operate safely in this range without the need of special controls or glycol additives. Leaving water temperatures below 40°F can result in evaporator suction temperatures below the freezing point of water. Therefore, a glycol solution additive is required that will protect the evaporator from freeze ups at lower operating suction temperatures. The full range of leaving fluid temperature using glycol is 24°F to 62°F. 10 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Water-Loop Heat Pump Applications Commercial systems typically include a number of units plumbed to a common piping system. Any unit plumbing maintenance work can introduce air into the piping system, therefore air elimination equipment is a major portion of the mechanical room plumbing. In piping systems expected to utilize water temperatures below 50°F [10°C], 1/2" [13mm] closed cell insulation is required on all piping surfaces to eliminate condensation. Metal to plastic threaded joints should never be employed due to their tendency to leak over time. Teflon tape thread sealant is recommended for NPT water connections (commercial class) to minimize internal fouling of the heat exchanger. Do not overtighten connections and route piping so as not to interfere with service or maintenance access. Hose kits are available from ClimateMaster for connection between the TMW Series and the piping system. The piping system should be flushed to remove dirt, piping chips, and other foreign material prior to operation. See Piping System Cleaning and Flushing Procedures later in this document. The flow rate is usually set between 2.25 gpm and 3 gpm per ton [2.9 l/m and 4.5 l/m per kW] of cooling capacity. ClimateMaster recommends 2.5 gpm per ton [3.2 l/m per kW] for most applications of water loop heat pumps. To insure proper maintenance and servicing, P/T ports are imperative for temperature and flow verification, as well as performance checks. Cooling Tower/Boiler Systems typically utilize a common loop maintained 60-90°F [16-32°C]. The use of a closed circuit evaporative cooling tower with a secondary heat exchanger between the tower and the water loop is recommended. If an open type cooling tower is used continuously, chemical treatment and filtering will be necessary. Figure 4: Source Water System (Not all components of system shown.

Unit has internal flush valves to allow alkaline flushing of just the heat exchanger. Pressure temperature plugs should be used so that flow and temperature can be measured. Supply and return water piping materials should be limited to copper, PE, or similar material. PVC or CPVC should never be used as they are incompatible with the POE and PVE oils used in HFC-410A products and piping system failure and property damage may result. WARNING! WARNING! Polyolester Oil, commonly known as POE oil, or Polyvinylether, commonly known as PVE oil, are synthetic oils used in many refrigeration systems including those with HFC-410A refrigerant. POE, or PVE oil, if it ever comes in contact with PVC or CPVS piping, may cause failure of the PVC/CPVC. PVC/CPVC piping should never be used as supply or return water piping with water source heat pump products containing HFC-410A as system failures and property damage may result. Water quantity should be plentiful and of good quality. Consult Table 5 for water quality guidelines. The unit has stainless steel braze plate heat exchangers. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. It is mandatory to install an intermediate heat exchanger to isolate an open loop from the heat pump loop on open well systems. Heat exchangers may over time lose heat exchange capabilities due to a build up of mineral deposits inside. These can be cleaned only by a qualified service mechanic as acid and special pumping equipment are required. Table 5: Water Quality Standards Water Containing Ammonia CaCO3 Alkalinity CaCO3 Hardness Chlorides Dissolved Solids Iron Manganese Nitrate pH Sulphate Concentration Less than 2.0 mg/l 30 - 500 mg/l 30 - 500 mg/l Less than 200 mg/l Less than 1000 mg/l Less than 5.0 mg/l Less than 4.0 mg/l Less than 100 mg/l 7.0 - 9.0 Less than 200 mg/l In areas with extremely hard water, the owner should be informed that the intermediate heat exchanger may require occasional flushing. Use a 2% phosphoric or sulfamic acid solution, on the unit side and manufacturer’s recommendation on ground water side. 12 Expansion Tank and Pump - Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. The expansion tank should be sized to handle at least one minute run time of the pump to prevent premature pump failure using its drawdown capacity rating. Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways depending on local building codes; i.e. recharge well, storm sewer, drain field, adjacent stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal. Consult your local building and zoning department to assure compliance in your area. Water Control Valve - Note the placement of the water control valve. Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Slow opening and closing valves are recommended to reduce water hammer. If water hammer persists, a mini-expansion tank can be mounted on the piping to help absorb the excess hammer shock. Ensure that the total ‘VA’ draw of any field-supplied valve can be supplied by the unit transformer. Flow Regulation - Flow regulation can be accomplished by two methods. First, most water control valves have a built in flow adjustment. By measuring the pressure drop through the unit heat exchanger, flow rate can be determined and compared to Table 6. Since the pressure is constantly varying, two pressure gauges might be needed. Simply adjust the water control valve until the desired flow of 1.5 to 2 gpm per ton is achieved. Secondly, a flow control device may be installed. The devices are typically an orifice of plastic material that is designed to allow a specified flow rate. These are mounted on the outlet of the water control valve. On occasion, these valves can produce a velocity noise that can be reduced by applying some back pressure. This is accomplished by slightly closing the leaving isolation valve of the well water setup.

CAUTION! The following instructions represent industry accepted installation practices for Closed Loop Earth Coupled Heat Pump Systems. They are provided to assist the contractor in installing trouble free ground loops. These instructions are recommendations only. State and Local Codes MUST be followed and installation MUST conform to ALL applicable Codes. It is the responsibility of the Installing contractor to determine and comply with ALL applicable Codes and Regulations. Pre-Installation - Prior to installation, locate and mark all existing underground utilities, piping, etc. Install loops for new construction before sidewalks, patios, driveways, and other construction has begun. During construction, accurately mark all ground loop piping on the plot plan as an aid in avoiding potential future damage to the installation. Antifreeze - In areas where minimum entering loop temperatures drop below 40°F [5°C] or where piping will be routed through areas subject to freezing, anti-freeze is needed. Alcohols and glycols are commonly used as antifreezes, however your local sales manager should be consulted for the antifreeze best suited to your area. Low temperature protection should be maintained to 15°F [9°C] below the lowest expected entering loop temperature. For example, if 30°F [-1°C] is the minimum expected entering loop temperature, the leaving loop temperature would be 25 to 22°F [-4 to -6°C] and low temperature protection should be at 15°F [-10°C] e.g. 30°F - 15°F = 15°F [-1°C - 9°C = -10°C]. All alcohols should be premixed and pumped from a reservoir outside of the building when possible or introduced under water level to prevent fuming. Initially calculate the total volume of fluid in the piping system. Then use the percentage by volume shown in Table 7 for the amount of antifreeze. Antifreeze concentration should be checked from a well mixed sample using a hydrometer to measure specific gravity. Table 7: Antifreeze Percentages by Volume Type Minimum Temperature for Low Temperature Protection 10°F [-12.2°C] 15°F [-9.4°C] 20°F [-6.7°C] 25°F [-3.9°C] Methanol 25% 21% 16% 10% 100% USP Food Grade Propylene Glycol 38% 25% 22% 15% Ethanol 29% 25% 20% 14% * Must not be denatured with any petroleum based product Piping Installation - All earth loop piping materials should be limited to only polyethylene fusion for inground sections of the loop. Galvanized or steel fitting should not be used at any time due to their tendency to corrode. All plastic to metal threaded fittings should be avoided due to their potential to leak in earth coupled applications and a flanged fitting substituted. P/T plugs should be used so that flow can be measured using the pressure drop of the unit heat exchanger in lieu of other flow measurement means. Earth loop temperatures can range between 25 to 110°F [-4 to 43°C], and 2.25 to 3 gpm of flow per ton [2.9 l/m to 3.9 l/m per kW] of cooling capacity is recommended in these applications. Upon completion of the ground loop piping, pressure test the loop to assure a leak free system. Horizontal Systems: Test individual loops as installed. Test entire system when all loops are assembled. Vertical U-Bends and Pond Loop Systems: Test Vertical U-bends and pond loop assemblies prior to installation with a test pressure of at least 100 psi [689 kPa]. Flushing the Earth Loop - Upon completion of system installation and testing, flush the system to remove all foreign objects and purge to remove all air. Flush the loop first with the unit isolated to avoid flushing debris from the loop into the unit heat exchanger. Water Control Valve - Note the placement of the water control valve. Always maintain water pressure in the heat exchanger by installing water control valves at the source out of the unit to prevent mineral precipitation. Position water high pressure switch between unit and valve. Pilot operated or slow closing valves are recommended to reduce water hammer. If water hammer persists, a mini-expansion tank can be mounted on the piping to help absorb the excess hammer shock. Insure that the total ‘VA’ draw of the valve can be supplied by the unit transformer. For instance, some slow closing valves can draw up to 35VA. This can overload smaller transformers depending on the other controls employed. A typical pilot operated solenoid valve draws approximately 15VA. Flow Regulation - Install on source in of unit. Flow regulation can be accomplished by two methods. First, most water control valves have a built in flow adjustment. By measuring the pressure drop through the unit heat exchanger, flow rate can be determined and compared to Table 6. Since the pressure is constantly varying, two pressure gauges might be needed. Simply adjust the water control valve until the desired flow of 2.5 to 3 gpm per ton [2.0 to 2.6 l/m per kW] is achieved. Secondly, a flow control device may be installed. The devices are typically an orifice of plastic material that is designed to allow a specified flow rate. These are mounted on the outlet of the water control valve. On occasion, these valves can produce a velocity noise that can be reduced by applying some back pressure. This is accomplished by slightly closing the leaving isolation valve of the well water setup. c l i m a t e m a s t e r. c o m 13 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Electrical - Line Voltage WARNING! To avoid possible injury or death due to electrical shock, open the power supply disconnect switch and secure it in an open position during installation. Electrical Connection - The compliance of the installation to relevant local and national codes is the responsibility of the installer. Before carrying out any electrical work, confirm that the main supply is isolated. The installer must ensure that the correct electrical drawing is available. Before power is applied to the system, the wiring should be visually inspected for loose connections or frayed terminal connections. All control wiring should follow wiring instructions supplied in the project submittal package. General Line Voltage Wiring - Be sure the available power is the same voltage and phase as that shown on the unit serial plate. Line and low voltage wiring must be done in accordance with local codes or the National Electric Code, whichever is applicable. Consult the unit wiring diagram located on the inside of the compressor access panel to ensure proper electrical hookup. All final electrical connections must be made with a length of flexible conduit to minimize vibration and sound transmission to the building. TMW Power Connection - Line voltage connection is made by connecting the incoming line voltage wires to L1, L2, and L3 on power distribution block. Consult electrical data table 8 for correct fuse size. Incoming Power Wiring - The power for all units is taken from a suitable fused disconnect power supply within the main panel and the electrical service enters the individual units through the top into the units control panel enclosure. Proper grounding is mandatory. The power supply shall be in compliance with all local and national codes. CAUTION! CAUTION! Use only copper conductors for field installed electrical wiring. Unit terminals are not designed to accept other types of conductors. WARNING! 208 Volt Operation - All 208-230 Volt units are factory wired for 208 Volt. The transformers may be switched to 230V operation as illustrated on the wiring diagram by switching the Red wire from H2 to H3 terminal on the transformer. All field installed wiring, including electrical ground, must comply with the National Electrical Code as well as all applicable local codes. Refer to the unit wiring diagrams for fuse sizes and a schematic of the field connections which must be made by the installing (or electrical) contractor.

High voltage is used to operate this equipment. Failure to observe standard electrical safety procedures may result in serious injury. Only persons qualified and / or properly trained should attempt to install, operate and maintain this equipment. These units come fully charged with refrigerant. Installation, and start – up should be accomplished by technicians who are fully certified to handle refrigerants, as required by 40 CRF Part 82, subpart F of the Recycling and Emissions Reduction Act. Scroll compressors are used in this equipment. Phase verification is required for proper rotation direction. Incorrect rotation will result in elevated sound and internal overload trip failure. Proper Voltage Balance - Occasionally, in three phase circuits, a voltage imbalance occurs between phases. It is not recommended to operate equipment when an imbalance greater that 2% occurs. This causes motors to run at high temperatures and may affect their longevity. The following example describes how to calculate the average voltage of the three phases to see if the imbalance is greater than 2%. Example: Line one = 226v Line two = 230v Line three = 228v The average is: 226+230+228 = 228v Next, 100(228-226) = 0.9% 228 The voltage imbalance of the three phase circuit is 0.9%. This is well under the 2% range. c l i m a t e m a s t e r. c o m 15 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Electrical - Low Voltage DDC Control Wiring - Control wiring cannot be installed in the same conduit as line voltage wiring or with wires that switch highly inductive loads such as contactor and relay coils. All wiring shall be in compliance with all local and national codes. Electrical Phase Sequencing - Proper clockwise rotation for scroll compressor motors is important to prevent damaging the compressors. ClimateMaster recommends the use of a phase sequence indicating instrument following the manufactures directions. Another alternative would be to “bump test” the compressors one at a time with pressure gauges attached to the high and low gauge ports of the compressors to check for proper rotation. Energize the compressor for a few seconds to ensure the discharge pressure gauge increases significantly. If the discharge pressure does not increase, proper rotation is reversed. Compressor rotation can be reversed by opening the main electrical disconnect and switching any two of the main power supply leads feeding that compressor’s contactor. ATTENTION INSTALLER 3 Phase Scroll Compressor Units • If this unit uses a 3 Phase Scroll Compressor, the following instructions MUST BE followed: - Unit power supply MUST BE wired in the proper sequence to avoid damage to the 3 Phase Scroll Compressor; - Scroll Compressors with INCORRECT rotation show the following characteristics: 1) High sound level; 2) High suction pressure and low discharge pressure; 3) Low current draw. - If any of the three above characteristics exist, swap two of the three supply wires at the disconnect/fuse block and recheck compressor for incorrect rotation. Low Voltage Knockouts are provided on top, sides, or front of unit. Run wires into low voltage section. Connect to terminal strips per wire diagram. 16 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Wiring Diagram Matrix All diagrams can be located online at climatemaster.com using the part numbers below.

This can easily be done if factory mounted water isolation valves are provided. Access to a floor drain is helpful when performing standard maintenance procedures. Back Washing - It may become evident from the recorded weekly log data that the performance of the TMW is gradually degrading. This could be due to a buildup of debris or sludge obstructing the free passage of flow through the heat exchangers. This debris can be removed by a back washing process, which involves the introduction of a forced, violent, backwards flow through the heat exchanger, using a carefully formulated flushing solution. To be effective, this back flow should be slightly higher than the normal flow, and in the opposite direction. The difficulties and practicality of this method depends on the back wash pumping system itself. Another method would be to back flush each heat exchanger using city water as opposed to system water (see Figure 5 – City Water Cleaning Arrangement). The back washing procedure is accomplished by isolating each individual heat exchanger and introducing the city water using a connection hose to the ¾” service port to flow in an opposite direction from the normal heat exchanger flow direction. On the opposite ¾” service port, connect a drain hose to run to a suitable floor drain. Continue back flow until all debris is removed. Chemical Clean In Place Washing Without Water Isolation Valves - Chemical Clean in place washing will typically provide the best debris removal, even from severely clogged heat exchangers. The cleaning tank, pump and pump strainer should be arranged in the manner shown in Figure 6 - In Place Cleaning Arrangement. The flow of the cleaning is arranged in the opposite flow to the normal operational direction. Connection points are provided using the 3/4” service ports at each heat exchanger. The cleaning solution used can be either a detergent or hot water to remove particles and simple cleaning. If correct water treatment has been implemented this should provide adequate cleaning for most situations. The solution can be pumped through the heat exchangers and allowed to “soak” for a time and then pumped again. CAUTION! CAUTION! Do not chemically clean heat exchangers with chloride based solutions.

A compressor run time equalization sequence is given to ensure even distribution of compressor run time. Unit power consumption is minimized by indexing the most efficient stages of cooling, optimizing heat transfer surface. The controls are two separate boards; the IO FLEX6126 and EX8160 expander board. The controls govern all significant events, timing and compressor staging, providing operator interface for all levels of setting and retrieving data. The controller directly senses the control parameters that govern the unit operation, such as Load and Source entering and leaving temperatures, both compressors’ winding temperatures, suction and discharge temperatures and pressures. Field Component Connections to the Controller Field integration is simplified by the use of the following minimum input devices: • A remote OFF, HEAT, COOL input for scheduling is required for unit operation. (not required if BAS is used) Connect 3 wires to 7, 9, 10 plus add jumper between 8 and 10. • Differential pressure sensors ADPS for both Load and Source water flows are required for unit operation (connect 6 wires to 13-17 at LVTB2, see wire diagram). • Voltage/phase monitor (phase loss/phase reversal, brown-out/black-out device) is recommended for unit operation. (If not used, add jumper wire, connect between 1 and 2 at LVTB2, see wire diagram.) • BAS or BacView6 (one per site). • Optional fault reset switch can be connected between 11 and 12 at LVTB2, see wire diagram. Controller Connections and Settings - Before wiring to, setting or changing the hardware address, make sure the controller power is off. The controller only reads the address when the unit is turned on. The controller has two rotary switches for assigning the module’s hardware address. One switch corresponds to the “tens” digit and the second switch corresponds to the “ones” digit, allowing for hardware-based addresses of 02 to 99. For example, if the unit’s address is two, set the tens switch to zero and the ones switch to two, as shown in Figure 7. The station ID for each MS/TP node must be unique on a MS/TP segment. The rotary address switches are used to set this unique ID. Set the communication BAUD rate with DIPS 1 and 2, see figure 7. 9600, 19.2K, 38.4K, or 76.8K available. Set the protocol with DIPS 5, 7, and 8, see figure 7. MSTP, N2, and Modbus are available. c l i m a t e m a s t e r. c o m 23 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Control System (continued) Alarm Codes - I/O FLEX6126 Board has LED near AO-2 that will flash alarm code. 1.

From the “Home” screen, you are easily guided to the main menu listings for the following categories by pressing one of the four menu buttons: Status, Setup, Service, Alarm. At the end of this delay, the first compressor will start and after a 5 minute timeout, the display will change to the default screen.

Access to this log is available through the keypad. (Figure 14) Chilled Water Flow Sensor - The controller has an input for a differential pressure sensor configured for sensor, which measures and displays pressure drops across the entering and leaving water. If the differential pressure drops below a predetermined setting for a fixed period of time, after the unit receives a “RUN” input signal, the unit will not be allowed to run and a water flow alarm condition is displayed. The alarm condition must be resolved, flow re-established, and a minimum pressure differential acknowledged by the differential pressure sensor. The alarm clears automatically (the alarm condition is logged for retention in the most recent 100 alarms) which constitutes an “OK to RUN” status. Setup Menu - System operation is determined by the values assigned to the system variables, as predominantly found in the Setup menu (Figure 12). The Setup menu lists a series of sub-menus: • • • • General System Settings Heating and Cooling Setpoint Menus Lead Compressor Rotation Setup Alarm Lockout Reset (or FN + 3) These variables are initially assigned a default value. For most applications, these values will provide optimum results. Once these values have been set, they are put in permanent memory and will remain, even when all power is removed from the TMW. c l i m a t e m a s t e r. c o m 29 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Control System (continued) Condenser Water Flow Sensor - The controller has an input for a differential pressure sensor, which measures and displays pressure drops across the condenser water main headers. If the differential pressure drops below a predetermined setting for a fixed period of time after the unit receives a “RUN” input signal, the unit will not be allowed to run, and a Source water flow alarm condition is displayed. This alarm condition must be resolved and flow re-established, and a minimum pressure differential acknowledged by the differential pressure sensor. The alarm clears automatically; however, the alarm condition is logged for permanent retention of the most recent 100 alarms. This will constitute an “OK to RUN” status. Alternatively, the controller can configure to accept a differential pressure sensor indicating proper Source water flow (refer to the wiring diagram), set to differential pressure sensor. Alarm Output - The relay output contact is closed whenever there is an active latching or non-latching alarm condition present relative to a fault parameter. TMW Status Output - The relay output contact is closed whenever all input signals to the unit are present and normal, indicating the requirement for the unit to operate when able. 30 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Control System Optional Features Building Automation System (BAS) Interface - Internal operational information is available where the TMW is to be integrated into a building system and monitored by the equipment of a controls manufacturer. Available protocols built into the Control System as standard are: • BACnet over MSTP • MODBUS • N2 High Discharge Temperature - During operation, should this temperature rise above 225ºF, the compressor will shut down. This requires resetting at the Controller after the temperature has cooled to below 175ºF. See Setup Menu for Alarm Menu display or press FN+3. Low Leaving Chilled Water Temperature - Below 36ºF - Evaporator freeze protection requires resetting at the Controller after the temperature has risen to 40ºF See Setup Menu for Alarm Menu display or press FN+3. Compressor Unloading - Compressor unloading routines are programmed into the controller. When any one of the compressor control parameters approaches a pre-limit condition, the Control System executes appropriate compressor unloading commands to avoid compressor lockout, thus maximizing the unit on time. High Leaving Condenser Water Temperature - Above 140ºF This requires resetting at the Controller after the temperature has fallen below 135ºF. See Setup Menu for Alarm Menu display or press FN+3. Compressor Minimum Off Delay - When a compressor is turned off, the compressor will remain off for this period of time. Communications Error - This signifies a loss of communication between any TMW controller and the BAS or BACView6. Compressor Minimum On Delay - When a compressor is turned on, the compressor will remain on for this period of time. This time can be cut short if an alarm condition is predicted. Miscellaneous Alarm Functions of the Control System • Loss of flow through the evaporator • Loss of flow through the condenser • Electrical voltage/phase failure • Temperature Sensor “Out-of-Range” error detects when an open or shorted sensor condition exists. ALARM FUNCTIONS OF THE CONTROL SYSTEM High Pressure Cutout - This requires resetting at both the TMW manual reset high pressure control switch and at the Controller’s software reset to resume operation See Setup Menu for Alarm Menu display or press FN+3. Low Pressure Cutout - This requires resetting at the Controller to resume operation.See page 5 Setup Menu for Alarm Menu display or press FN+3. Compressor Thermal Protector Fault - This would occur if the motor protector sensed an overload trip in the compressor motor. It would also occur if any component in the motor protector circuit failed to open. This requires resetting at the Controller. See Setup Menu for Alarm Menu display or press FN+3. Low Suction Temperature - During operation, should this temperature drop to 28ºF, the compressor will shut down. This requires resetting at the Controller after the temperature has risen above 33ºF. See Setup Menu for Alarm Menu display or press FN+3. c l i m a t e m a s t e r. c o m 31 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Control Sequence of Operation from BAS A.

Do not install in an area subject to freezing or where humidity levels can cause cabinet condensation. Power Supply - A voltage variation of +/- 10% of nameplate utilization voltage is acceptable. Operation and performance is primarily dependent upon water temperatures, water flow rates and ambient air temperature. This water to water heat pump is capable of operating over a wide temperature range and with flow rates of between 1.5 GPM (.1 l/s) and 3 GPM (.19 l/s) per ton, however usually no more than one of these factors may be at a minimum or maximum level at a time. The commissioning table indicates water temperatures which are suitable for initial unit commissioning in an environment where the flow rate and water temperature is not yet stable and to avoid nuisance shut down of the units freeze and refrigerant pressure safeties. For more specific unit performance reference the product catalog, the submittal data sheets or contact your supplier for assistance.

Proper maintenance of strainers and checking pH are also as important. Follow the instructions below to properly clean and flush the system: 1. Verify electrical power to the unit is disconnected. 2. Install the system with the supply hose connected directly to the return riser valve. Use a single length of flexible hose. 3. Open all air vents. Fill the system with the water. DO NOT allow system to overflow. Bleed all air from the system. Pressurize and check the system for leaks and repair appropriately. 4. Verify all strainers are in place. Start the pumps, and systematically check each vent to ensure all air is bled from the system. 5. Verify make-up water is available. Adjust make-up water appropriately to replace the air which was bled from the system. Check and adjust the water/air level in the expansion tank. 6. If possible, raise the Source loop temperature to approximately 85ºF (29ºC). Open the a drain at the lowest point in the system. Adjust the make-up water replacement rate to equal the rate of bleed. 7. Refill the system and add phosporic or sulfamic acid for a 2% solution. If possible, raise the Source loop temperature to approximately 100°F [38°C]. Circulate the solution for a minimum of 8 to 24 hours. At the end of this period, shut off the circulating pump and drain the solution. Repeat system cleaning if desired. 8. When the cleaning process is complete, remove the short-circuited hoses. Reconnect the hoses to the proper supply, and return connections to each of the units. Refill the system and bleed off all air. 9. Test the system pH with litmus paper. The system water should be slightly alkaline (pH 7.0-9.0). Add chemicals, as appropriate, to maintain acidity levels. WARNING! WARNING! Polyolester Oil, commonly known as POE oil, or Polyvinylether, commonly known as PVE oil, are synthetic oils used in many refrigeration systems including those with HFC-410A refrigerant. POE, or PVE oil, if it ever comes in contact with PVC or CPVS piping, may cause failure of the PVC/CPVC. PVC/CPVC piping should never be used as supply or return water piping with water source heat pump products containing HFC-410A as system failures and property damage may result. 10. When the system is successfully cleaned, flushed, refilled and bled, check the main system panels, safety cutouts and alarms. Set the controls to properly maintain loop temperatures. 11. Extract three water samples from the Load and Source water system using bottles provided from the Water Sample test kit. Confirm that the sample bottles are filled to the top leaving no air in the bottles. All six sample bottles must have labels filled out per instruction included with the bottles. Ship the bottles immediately to the appropriate water testing laboratory as per the instructions included with the bottles. CAUTION! CAUTION! DO NOT use 'stop leak' or any similar chemical agent in this system. Addition of these chemicals to the loop water will foul the system and inhibit unit operation. c l i m a t e m a s t e r. c o m 39 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Pre-Start Up Procedures WARNING! WARNING! Do Not operate compressors for pre-start check. Prior to unit start up, there are certain essential checks which must be completed. Failure to carry out these checks could result in damage to the TMW voiding the warranty. Assembly - ClimateMaster recommends locking down the unit to a concrete base or to three 4” base mounting rails using the six bolt holes provided in each base pan. Confirm that bolts have been properly tightened during installation. Electrical - It is imperative to turn off the main electrical power supply and follow proper lock-out, tag-out procedures prior to servicing any of the TMW electrical components. The following procedures can be performed only after the electrical power is confirmed to be off: 1. The installation must be inspected and approved by the respective agent and be in compliance with all local and national electrical codes. 2. Check and tighten as required all electrical terminal connections. Utilize any lock-out/ tag-out procedures required for your project location when performing this operation. If no procedure exists take all precautions necessary to prevent the power from being turned on. A systematic tightening of all terminals inside the electrical control panel should be carried out. This will include the compressor motor terminals, which would require removal of the compressor terminal cover. Check connections at each safety and every termination in the panel. 3. Low voltage wiring can enter top, left hand side, or front. Control wires should be #18 AWG minimum up to 50 feet, #16 AWG minimum up to 100 feet, rated at 60°C minimum. Tag wire inside control box with component it is coming from. 4. All field connections should be checked for tightness. 5. Check all fuses for proper sizing as indicated on the data plate and/or the electrical diagram on the inside door of the electrical panel. 6. Verify line voltage is within acceptable range, see electrical table 8. 7. 208/230 model, verify transformer is wired to correct TAP, shipped for 208V, rewire if needed. 40 DANGER (OHFWULFVKRFNKD]DUG 0D\UHVXOWLQLQMXU\RUGHDWK 'LVFRQQHFWSRZHUVXSSO\LHV EHIRUHVHUYLFLQJ 5HIHUVHUYLFLQJWRTXDOLILHG VHUYLFHSHUVRQQHO &$87,21 8QLWWREHVHUYLFHGE\TXDOLILHG SHUVRQQHORQO\ 5HIULJHUDQWV\VWHPXQGHU SUHVVXUH 5HOLHYHSUHVVXUHEHIRUHXVLQJ WRXUFK 5HFRYHUUHIULJHUDQWDQGVWRUHRU GLVSRVHRISURSHUO\ DANGER 5LVTXHGHFKRFpOHFWULTXH 5pVXOWDWGHPDLGDQVGRPPDJHV RXODPRUW 'HEUDQFKHUDYDQWGҋHQWUHSUHQGUH OHGpSDQQDJHGHOҋDSSDUHLO &RQVXOWHUXQUpSDUDWHXUTXDOLILH SRXUOHGpSDQQDJH 5(&29(5 5()5,*(5$17 $77(17,21 &RQILHUODPDLQWHQDQFHiXQ WHFKQLFLHQTXDOLILH /HV\VWpPHIULJRULILTXHVRXV SUHVVLRQ 'pFRPSULPHUDYDQWGҋH[SRVHUi ODIODPPH 5pFXSHUpUOHIULJRULJHQHHWOH VWRFNHURXOHGpWULUH FRUUHFWHPHQW 8.

Turn compressor selector switches inside the TMW control panel (low voltage side) to the off position. 2. Ensure the correct fuses are installed in the control transformer fuse blocks. Turn on the power. The “Power” light should be on. 3. Connect BACView6 to I/O flex board at J6 (see wire diagram E-4). 4. Override the Controller’s DDC outputs to the compressors. Within the “Service Menu” of the BACView6 index to the “Diagnostics Manual Mode” section to engage the compressors individually for startup purposes. Index to the “M1 Manual Mode” prompt so the cursor is at the “Off” prompt to the right. Press “Enter”. Use the increment key so the “Off” prompt changes to “On” and then press “Enter”, or press the “OK” key. Index down to the “MC1 Manual Mode On” prompt so the cursor is at the “Off” prompt to the right. Press “Enter”. Use the increment key so the “Off” prompt changes to “On” and then press “Enter”, or press the “OK” key. Inside the low voltage control section (left-most control door),turn the Compressor 1 switch ON to bump compressor 1 and check for proper rotation using pressure gauges. Once this is complete and correct rotation is verified, turn the compressor 1 switch off and reverse the manual mode for M1C1 compressor so it is “Off” by similar prompts as outlined above. Use this same technique to manually override the M1C2 compressor to the “On” state. Turn on the switch marked “Compressor 2” to bump the compressor and verify that circuit 2 compressor has correct rotation. Always use proper electrical safety precautions. 5. Slowly close the Load water inlet isolating valve and note that the pressure differential flow sensor stops the machine. Note the flow rate at which this occurs. If too much flow is lost before unit is stopped, reset switch setting. The pressure differential flow sensor should be set so the unit shuts down when the flow rate to each water circuit drops below 60% of rated AHRI full load conditions (indicating a 10°F temperature change through the Load heat exchanger). 6. 7. 8. Slowly close the source water inlet isolating valve and note that the pressure differential flow sensor stops the unit. Note the flow rate at which this occurs. If too much flow is lost before unit is stopped, reset switch setting. The pressure differential flow sensor should be set so the unit shuts down when the flow rate to each Source water circuit drops below 25% of rated AHRI full load conditions (indicating a 10°F temperature change through the Source heat exchanger). Repeat the tests of all other safety interlocks which may be connected. The antifreeze temperature sensor at the Load outlet should be set to stop the compressors from operating when the leaving chilled water temperature drops below 36°F. WARNING! WARNING! To avoid possible injury or death due to electric shock, open the power supply disconnect switch and secure it in an open position during installation. CAUTION! CAUTION! Use only copper conductors for field installed electrical wiring. Unit terminals are not designed to accept other types of conductors. WARNING WARNING! This unit contains HFC-(R410A), an azeotropic mixture of R-32 (Difluoromethane) and R-125 (Pentafluoroethane). DO NOT VENT HFC-(R410A) to the atmosphere. The U.S. Clean Air Act requires the recovery of any residual refrigerant. Do not use R-22 service equipment or components on R410A systems. c l i m a t e m a s t e r. c o m 43 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Unit Start Up Procedure WARNING! WARNING! When the disconnect switch is closed, high voltage is present in some areas of the electrical panel. Exercise caution when working with energized equipment. Unit Start Up (Continued) 1. Built into the logic of the ClimateMaster DDC Controller is an anti-short cycle timer which will prevent the compressors from re-starting immediately following a compressor shutdown. 2. If the chilled water temperature is above the normal operating level (greater than 90°F), all load should be removed from the chilled water system and the suction temperature should be monitored to prevent high current draw. 3. If the Source water temperature is below the normal operating level (less that 60°F), ensure that the Source water temperature control is in the correct position. 4. When all temperatures are within operating limits, all high and low pressure safety switches should be tested for each refrigeration system. 5. The Source temperature controller should be checked. Once stable conditions have been achieved, the refrigeration system’s high and low pressures, compressor amp draw, voltage input level, and water system temperatures and pressures should be logged for each unit module separately. 6. Check that oil level is between 1/3 and 1/2 of the sight glass. 7. The action of the controller should be checked for correct operation and control. Adjusting Unit Charge and TXV’s Using Superheat and Subcooling Method - Due to varying installation conditions/applications and to optimize performance, proper refrigerant charge and TXV adjustment must be confirmed. After checking compressor rotation, choose a circuit to be tested first. Connect test equipment to monitor the suction Line and Liquid Line temperatures simultaneously. Place a manifold gauge set on the suction line and liquid line. Start the compressor. As long as the suction pressure is high enough to prevent the low pressure switch from tripping, run compressor. After compressor runs at least five minutes, verify proper superheat by subtracting the saturated evaporative temperature from the suction line temperature. The saturated evaporative temperature is found by converting the suction pressure reading on the manifold gauge, to the related temperature. Proper superheat temperature range is 6-12°F. If superheat is low, this may indicate that TXV is overfeeding. To adjust the TXV, turn the adjustment stem clockwise. This will cause the superheat to rise. Wait five minutes before checking results of adjustment. Repeat until desired superheat is achieved. After verifying proper superheat, then verify proper subcooling. This is accomplished by subtracting liquid line temperature from the saturated condensing temperature. Saturated condensing temperature is found by converting the liquid line pressure reading on the manifold gauge, to the related temperature. Normal subcooling temperature range, at the condenser, is 5-15°F BUT for total accuracy please follow the charge recommendations found in the selection program. If subcooling is too low, then refrigerant must be added to the system. Add charge and wait five minutes before checking results. If subcooling is too high, then refrigerant must be removed from the system. CAUTION! CAUTION! Do not charge to achieve subcooling temperature when the TXV is overfeeding. If the TXV is overfeeding, readings may still indicate low subcooling and low superheat, but circuit may not be undercharged. WARNING! WARNING! Verify ALL water controls are open and allow water flow prior to engaging the compressor. Freezing of the brazed plate heat exchangers or water lines will permanently damage the heat pump. 44 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Unit Start Up Procedure Run Compressor for 5 Minutes Is Superheat in Range?

Periodically conduct a visual inspection of the unit to identify problems before they reach the point of failure. As with any mechanical system, it is necessary to conduct a series of checks to the TMW unit to confirm correct operation. Daily • A daily operational log should be kept. • Perform visual inspection. • Record entering and leaving Load water and Source water temperatures and pressures. • Note any problems that may exist and immediately plan for further investigation. If repair is necessary, schedule for earliest possible date. • Properly document all data taken. Weekly • Perform visual inspection. • Properly document all data taken. • Note any problems that may exist. Immediately plan for further investigation. If repair is necessary, schedule for earliest possible date. • Review daily log from previous week. Quarterly • Check controller operating parameters and setpoints. • Check temperature drop/rise on each individual heat exchanger.* • Check compressor oil level. • Check compressor oil color. • Check water flow rates and pressure drops across Load and Source heat exchangers. • Properly document all data taken. 46 * The temperature drop/rise on a fully loaded (both compressors) heat exchanger is generally 10°F. If only one compressor is running the temperature drop/rise will be approximately 5°F. Some projects are designed to have a higher temperature drop on either the Load or the Source depending on application. Consult log sheet for your project for these values. If the temperature drop/ rise is greater than the design, your heat exchanger may need to be back flushed or the strainer may need to be cleaned. Annual • Back flush all heat exchangers. If fouling is suspected use only ClimateMaster recommended descalers (see Chemical Clean In Place Washing). • Remove and clean all waterside strainers. • Manually operate all waterside isolation valves, if provided, on each module. • Check all electrical connections for tightness. • Perform leak check on all refrigerant circuits. • Check all header piping couplings for tightness. • Check oil level and color on each compressor. • Check and test all refrigerant safeties for proper operation. • Check all peripheral systems for proper operation. • Verify setpoints, sensors, and general control configuration. • Properly document all data taken. C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Operation and Maintenance Chemical Clean in Place Washing with Water Isolation Valves - Chemical Clean in place washing will typically provide the best debris removal, even from severely clogged heat exchangers. The cleaning tank, pump and pump strainer should be arranged in the manner shown in Figure 6 - In Place Cleaning Arrangement. The flow of the cleaning is arranged in the opposite flow to the normal operational direction. Connection points are provided using the ¾” service ports at each heat exchanger. The cleaning solution used can be either a detergent or hot water to remove particles and simple cleaning. If correct water treatment has been implemented this should provide adequate cleaning for most situations. The solution can be pumped through the heat exchangers and allowed to soak for a time and then pumped again. If it is required to remove carbonates, then an acidic wash should be used. A 2% solution of phosphoric or sulfamic acid in pure water is generally acceptable. These acid solutions should only be allowed to circulate within the heat exchanger for 10 to 15 minutes, followed by a thorough pure water flush for 10 to 15 minutes. Hydrochloric or sulfuric acids must not be used. In any case, consult the chemical supplier to establish the correct handling process. Once the washing is complete, the solution should be flushed out completely by pumping clean, fresh water through the unit. To achieve a reasonable level of dilution, it may be required to change the water several times. After cleaning, the water quality and water treatment should be confirmed. c l i m a t e m a s t e r. c o m 47 CLIMATEMASTER WATER-SOURCE HEAT PUMPS Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2016 Operational Limitations Table 9 Voltage Limitations Compressor Operating Limitations TMW Maximum Compression Ratio The following voltage limitations are absolute and operation beyond these limitations may cause serious damage to the compressor. 5.7:1 Minimum Operating Pressure Differential (PSI) 85 Maximum Operating Pressure Differential (PSI) 475 Minimum Discharge Pressure (PSIG) 215 Maximum Discharge Pressure (PSIG) 590 Minimum Suction Pressure (No Glycol) (PSIG) 105 Minimum Suction Pressure (With Glycol) (PSIG) 70 Maximum Suction Pressure (PSIG) 175 Maximum Discharge Temperature (ºF) 265 Minimum Subcooling (ºF) 5 Maximum Subcooling (ºF) 15 Nominal Voltage Minimum Voltage Maximum Voltage Minimum Superheat at Compressor (ºF) 6 208/230/3/60 187 253 Maximum Superheat at Compressor (ºF) 12 460/3/60 414 506 Maximum Oil Temperature (Max) (ºF) 200 575/3/60 518 632 Maximum Saturation Discharge Temperature (ºF) 145 Water Flow Data TMW360 TMW600 TMW840 Minimum Load Water Flow (GPM) 45 75 105 Maximum Load Water Flow (GPM) 90 150 210 Minimum Source Water Flow (GPM) 45 75 105 Maximum Source Water Flow (GPM) 90 150 210 Minimum Leaving Load Water Temperature (No Glycol) (ºF) C 40 40 40 Minimum Leaving Load Water Temperature (with Glycol) (ºF) C 20 20 20 C 62 62 62 H 135 135 135 Minimum Load Water Differential Temperature (ºF) 5 5.4 5.9 Maximum Load Water Differential Temperature (ºF) 20 20 20 C 60 60 60 H (with Glycol) 30 30 30 Minimum Source Water Differential Temperature (ºF) 6.5 6.9 7.2 Maximum Source Water Differential Temperature (ºF) 30 30 30 C 135 135 135 H 62 62 62 Maximum Leaving Load Water Temperature (ºF) Minimum Entering Source Water Temperature (ºF) Maximum Leaving Source Water Temperature (ºF) Equipment Room Data Minimum Equipment Room Ambient Temperature (ºF) 55 55 55 Maximum Equipment Room Ambient Temperature (ºF) 104 104 104 C=Cooling, H=Heating 48 C l i m a t e M a s t e r Wa t e r - S o u r c e H e a t P u m p s THE SMART SOLUTION FOR ENERGY EFFICIENCY Tranquility ® Large Water-to-Water (TMW) Series Rev.: 12 February, 2106 Compressor Information Compressor Information - The compressors used in the ClimateMaster heat pumps are scroll compressors. They are highly efficient and extremely reliable. However, the information contained in this manual will be useful for their care. Compressor Rotation - All scroll-type machines are unidirectional and will only compress in one direction. Operating in the reverse rotation can be destructive and will be indicated by a load operating noise together with a lack of compression. Compressor Lubrication - The compressor operates on a sealed system and oil can only be lost if leak occurs. There are few cases when oil will need to be added to a machine in normal operation. Oil Type - The oil in TMW scroll compressors is either polyester type oil, (POE), or polyvinylester oil (PVE), and is intended for R-410A refrigerant use. All refrigerant oils require special handling and should be protected from contamination. They are extremely hygroscopic and will absorb moisture rapidly from the air. It is strongly recommended to store and dispense all refrigerant oil from sealed metal cans. Oil Type POE PVE Oil Levels - The oil level in the compressor should be checked with the compressor running. The compressor oil level may vary during operation and particularly on the start-up. The normal operating compressor oil level should be between 1/3 and 1/2 of the sight glass. During operation a certain amount of oil maybe carried out into the refrigerant system. The system has been designed to allow the oil to return back to the compressor. If the level in the sight glass falls, it may be due to the operating conditions and enough time should be given to allow the oil to return before more oil is added. This could take up to 6 hours of operation. The compressor should not be allowed to operate with oil level less than 1/8 of the sight glass for an extended period of time. (Longer than 4-6 hours). Adding Oil - The compressor must never be run in a vacuum. A suitable hydraulic pump should be used to add oil and reserved for this process. Oil should only be added to a compressor while it is operating to observe valid oil sight glass levels. Oil is pressure-injected either into a gauge connection on the suction line or injected into the oil process port at the bottom of the compressor housing. Only enough oil should be added to raise the level above the sight glass point.

The service technician should be familiar with the following codes: • ASHRAE Standard Safety Code for Mechanical Refrigeration, ANSI/ASHRAE 15-1978 • American National Standard Code for Pressure Piping, ANSI B31.5-1974 Factory Tested - ClimateMaster units have been pressure-tested, evacuated and fully charged and run tested at design water flow rates prior to shipment. In the unlikely event that a refrigerant leak is detected at startup, the following guidelines should be consulted before reprocessing the refrigeration systems. Refrigerant System Recharging - Debris and moisture can enter copper tubing in a matter of minutes. All tubing, coil connections, or any refrigerant containing portions should be temporarily capped or sealed to keep contaminants to a minimum. Filter driers should be opened just prior to brazing into the system to prevent moisture infiltration whenever possible. After all of the repairs have been made to the refrigeration system, a pressure test using refrigerant and nitrogen should be performed. Pressurize the system with dry nitrogen to 20 psi and check for any obvious leaks. If no leaks are present introduce a “trace” amount of refrigerant to the system (raise system pressure to 30-40 psi). With a dry nitrogen tank equipped with a regulator set to 150 psi, continue to pressurize the system to 150 psi. Using a leak detector, carefully check the system for any remaining leaks. If the system is free of leaks you may release the pressure. Evacuating the System - The compressors should never be run while the system is in a vacuum. This could cause immediate failure to the compressors. After the system has been leak tested and sealed, any moisture that entered the system should be dehydrated and removed. While the pressure is reduced under a vacuum, the boiling point of moisture trapped inside the lines is reduced also. A pressure of .0095 PSIA, or 500 microns absolute pressure or better must be reached and sustained for several hours in order for the system to be considered free from moisture. It is necessary to use a micron meter equipped with an absolute pressure gauge (or transducer) to take this reading. ClimateMaster recommends the double evacuation process to ensure the proper removal of moisture and contaminants from the refrigeration system. After the initial vacuum is reached and held on the system, allow dry nitrogen back into the system until the pressure reaches zero PSIG or slightly higher. Then, repeat the entire evacuation process described above. The 50 evacuation process is considered complete ONLY after a successful “blank-off” test is performed. A “blank-off” test is defined as: a) pulling a vacuum level less than 500 microns on the system and holding it for several hours; b) record the vacuum level in the system in microns, then close off the vacuum pump from the system for 15 minutes, and continue to monitor the micron level inside the refrigeration system; c) if the vacuum level inside the system does NOT rise more than 400 microns above the recorded vacuum level at the start of the 15 minute period, then the evacuation process is complete. If the vacuum level rises more than 400 microns in 15 minutes, then continue to evacuate the system for 1-2 hours, and then repeat a “blank-off” test. Recharging the System - After all repairs have been completed, the system has been leak tested, and proper vacuum pressures have been reached and maintained, refrigerant may be recharged into the system. With a known weight of refrigerant in the cylinder, use the gage manifold set to connect the cylinder’s liquid charging port to the charging access port near the refrigerant liquid line valve. Open the compressor suction and discharge line valves. Gradually meter the appropriate weight of liquid refrigerant into the condenser side of the system first, until no additional refrigerant can be dispensed. Accurate refrigerant charge per circuit may be found in the Physical Data information on page 6. Then continue the charging process by filling the evaporator side of the system with refrigerant. Close the refrigerant cylinder charging port, close all gage manifold ports and start the compressor. Be careful when continuing to charge the balance of the refrigerant, constantly maintaining a positive compressor suction pressure (>25 PSIG) at all times. WARNING! WARNING! To avoid the release of refrigerant into the atmosphere, the refrigerant circuit of this unit must be serviced only by technicians who meet local, state and federal proficiency requirements. WARNING! WARNING! All refrigerant discharged from this unit must be recovered WITHOUT EXCEPTION. Technicians must follow industry accepted guidelines and all local, state and federal statutes for the recovery and disposal of refrigerants. WARNING! WARNING! If a compressor is removed from this unit, system refrigerant circuit oil will remain in the compressor. To avoid leakage of compressor oil, the refrigerant lines of the compressor must be sealed after it is removed.

Pumps for Load and Source water supply shall be started by others. When proof of flow is established in both the Load and Source water lines, the TMW shall start. The “Chilled Water Supply” (CHWS) temperature sensor (TS1), located in the discharge line, shall be used to cycle compressor stages sequentially to maintain setpoint of 44°F (adjustable from the LED Display/Keypad of the BACView6, or remotely through a BAS communications protocol (e.g. BACnet, Modbus or N2). TMW will be disabled until “Chilled Water Return” (CHWR) temperature sensor is below 90°F and “Source Water Supply” (SWS) temperature sensor is above 60°F. The compressor with most run time will de-energize as the setpoint is satisfied, and compressor with least run time will energize as additional capacity is required. If a fault is detected the compressor will be disabled and displayed on the DDC Controller LED display. (Faults must be manually reset at the unit by momentary contact between 11 and 12 on terminal block LVTB2). The Unit Status and Run Time in hours for each compressor can be displayed on the BACView6. Common Alarm contact and Unit Status contact is provided at the panel. Each unit has 2 compressors.

Optional motorized valves includes ¾” fill and flush valves. Y Type Strainers: 1. Drain piping. 2. Vent line to relieve pressure. 3. Loosen flange bolts (flanged ends). 4. Secure necessary lifting equipment to strainer assembly. 5. Remove inlet/outlet flange bolts (flanged end), or unthread (threaded ends) and carefully remove strainer. 6. Tighten cover. The strainer is ready for line start-up. Motorized source water valve provide head pressure regulation for low entering condenser water temperature applications (less than 60°F), in cooling. This is required for units intended for both heating and cooling, optional for other applications. Motorized Load water valve is optional, would be required for variable speed pumping. FIELD INSTALLED OPTIONS Strainer Installation Instructions 1. Ensure all machined surfaces are free of defects and that the inside of the strainer is free of foreign objects. 2. The strainer should be installed so that the drain connection is pointed downwards. 3. For flanged end strainers the flange bolting should be tightened gradually in a back and forth clockwise motion. Threaded end strainers should use an appropriate sealant. 4. Once installed increase line pressure gradually and check for leakage around joints. 5. If the strainer is supplied with a start-up screen monitor pressure drop carefully. 6. Isolation valves should be installed for ease of maintenance of strainers. IMPORTANT: Ultimate responsibility for strainer and material selection rest with the end-user or facility manager, as only the end-user or facility manager knows the particular application and operating parameters to which the strainer will be subjected. ClimateMaster recommends basket type for Source side. Basket Type Strainers 1. Drain Piping. 2. Vent line to relieve pressure. 3. Loosen cover and open to access basket. 4. Remove, clean and replace basket in original position. (Note: In some instances a high pressure water jet or steam may be required for effective cleaning). 5. Inspect cover gasket for damage. If necessary replace. (Note: If spiral wound gaskets have been used, they must be replaced and cannot be used again). 6. Tighten cover. The strainer is ready for line start-up. Maintenance Instructions - For maximum efficiency determine the length of time it takes for the pressure drop to double that in the clean condition. Once the pressure drop reaches an unacceptable value, shut down line and follow the Strainer Removal Instructions above. A pressure gauge installed before and after the strainer in-line will indicate pressure loss due to clogging and may be used to determine when cleaning is required. Troubleshooting Guides and Diagnostic Techniques - After pressurizing inspect cover and other joints for leakage. Gasket replacement or cover tightening is necessary if leakage occurs. If the required filtration is not taking place, ensure the screen is installed in the correct position, and that the screen is mounted flush to the upper and lower seating surfaces. CAUTION! CAUTION! CAUTION! Prior to dismantling the strainer for cleaning, it is imperative that the strainer assembly is isolated and completely de-pressurized. 52 CAUTION! Caution should be taken due to possible emission of process material from piping.
