General Information

Safety

Warnings, cautions and notices appear throughout this manual. Read these items carefully before attempting any installation, service or troubleshooting of the equipment.

DANGER: Indicates an immediate hazardous situation, which if not avoided will result in death or serious injury. DANGER labels on unit access panels must be observed.

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. If a compressor is removed from this unit, refrigerant circuit oil will remain in the compressor. To avoid leakage of compressor oil, refrigerant lines of the compressor must be sealed after it is removed.

WARNING: Indicates a potentially hazardous situation, which if not avoided could result in death or serious injury.

CAUTION: Indicates a potentially hazardous situation or an unsafe practice, which if not avoided could result in minor or moderate injury or product or property damage.

NOTICE: Notifi cation of installation, operation or maintenance information, which is important, but which is not hazard-related.

WARNING!

WARNING! The EarthPure ® Application and Service

Manual should be read and understood before attempting to service refrigerant circuits with HFC-410A.

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 profi ciency requirements.

CAUTION!

CAUTION! To avoid equipment damage, DO NOT use these units as a source of heating or cooling during the construction process. The mechanical components and fi lters will quickly become clogged with construction dirt and debris, which may cause system damage.

WARNING!

WARNING! This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Inspection - Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the packaging of each unit, and inspect each unit for damage. Insure that 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 fi led within 15 days, the freight company can deny the claim without recourse. Note: It is the responsibility of the purchaser to fi le all necessary claims with the carrier.

Notify your equipment supplier of all damage within fi fteen (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.

Unit Protection - Cover units on the job site with either the original packaging 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, fi ttings, and valves before installing any of the system components. Remove any dirt or debris found in or on these components.

Pre-Installation - Installation, Operation, and

Maintenance instructions are provided with each unit.

Horizontal equipment is designed for installation above false ceiling or in a ceiling plenum. Other unit confi gurations are typically installed in a mechanical room. The installation site chosen should include adequate service clearance around the unit. Before unit start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check the system before operation.

R e v i s e d : 2 5 J u l y, 2 0 1 7

General Information

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 original packaging until installation is complete and all plastering, painting, etc. is fi nished.

3. Verify refrigerant tubing is free of kinks or dents and that it does not touch other unit components.

4. Inspect all electrical connections. Connections must be clean and tight at the terminals.

5. Some airfl ow patterns and some control box locations are fi eld convertible. Locate the conversion section of this IOM.

CAUTION!

CAUTION! All three phase scroll compressors must have direction of rotation verifi ed at start-up. Verifi cation 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 signifi cantly 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.

Horizontal Unit Location - Units are not designed for outdoor installation. Locate the unit in an INDOOR area that allows enough space for service personnel to perform typical maintenance or repairs without removing unit from the ceiling. Horizontal units are typically installed above a false ceiling or in a ceiling plenum. Never install units in areas subject to freezing or where humidity levels could cause cabinet condensation (such as unconditioned spaces subject to 100% outside air). Consideration should be given to access for easy removal of the fi lter and access panels.

Provide suffi cient room to make water, electrical, and duct connection(s). Allow 91 cm clearance for servicing unit through all access panels.

If the unit is located in a confi ned space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be diffi cult to remove after the unit is installed should be removed prior to setting the unit. Refer to Figure 3 for an illustration of a typical installation. Refer to unit submittal data or engineering design guide for dimensional data.

Conform to the following guidelines when selecting unit location:

1. Provide a hinged access door in concealed-spline or plaster ceilings. Provide removable ceiling tiles in T-bar or lay-in ceilings. Refer to horizontal unit dimensions for specifi c series and model in unit submittal data. Size the access opening to accommodate the service technician during the removal or replacement of the compressor and the removal or installation of the unit itself.

2. Provide access to hanger brackets, water valves and fi ttings. Provide screwdriver clearance to access panels, discharge collars and all electrical connections.

3. DO NOT obstruct the space beneath the unit with piping, electrical cables and other items that prohibit future removal of components or the unit itself.

4. Use a manual portable jack/lift to lift and support the weight of the unit during installation and servicing.

The installation of water source heat pump units and all associated components, parts and accessories which make up the installation shall 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.

Mounting Horizontal Units

Horizontal units have 4 hanger brackets partially attached at the factory, one at each corner. Enclosed within the unit there is a hanger kit hardware bag containing vibration isolation grommets, washers, screws and a hanger installation instruction page. One additional screw from the hardware bag must be added to each hanger bracket before unit installation.Tighten each screw to 75 in-lbs (8.5 Nm). See Figure 1. Refer to the hanger installation instruction page contained in the hardware bag for details of fi nal hanger bracket attachment and unit suspension. See Figure 1a.

Use four (4) fi eld supplied threaded rods and factory provided vibration isolators to suspend the unit. Safely lift the unit into position supporting the bottom of the unit. Ensure the top of the unit is not in contact with any external objects. Connect the top end of the 4 all-thread rods, slide rods through the brackets and grommet then assemble washers and double nuts at each rod. Ensure that the unit is approximately level and that the threaded rod extends past the nuts.

Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units

(less than 8.8 kW) ensure that unit pitch does not cause condensate leaks inside the cabinet.

Air Coil - To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended for both sides of the coil. A thorough water rinse should follow. UV based anti-bacterial systems may damage coated air coils.

Notice!

Installation Note - Ducted Return: Many horizontal WSHPs are installed in a return air ceiling plenum application (above ceiling). Vertical WSHPs are commonly installed in a mechanical room with free return (e.g. louvered door). Therefore, fi lter rails are the industry standard and are included on ClimateMaster commercial heat pumps for the purposes of holding the fi lter only. For ducted return applications, the fi lter rail must be removed and replaced with a duct fl ange or fi lter frame. Canvas or fl exible connectors should also be used to minimize vibration between the unit and ductwork.

Front

Return air

Note: It is not possible to fi eld convert return air between left or right return models due to the necessity of refrigeration copper piping changes.

Preparation - Field conversion must be completed on the ground. If the unit is already hung it should be taken down for the fi eld conversion. Place in a welllighted area. Conversion should only be attempted by a qualifi ed service technician.

Side to Back Discharge Conversion

1. Remove back panel and side access panel

2. Loosen 2 motor slide nuts, raise motor slide assembly and remove belt and motor sheave.

3. Remove blower sheave. Remove motor bolts and carefully remove motor.

4. Remove 2 motor clips and reattach to opposite side.

5. Unbolt (3 per side) complete housing assembly.

6. Rotate complete assembly into new position. Locate over mounting holes in base, reattach using 3 bolts per side.

7. Mount motor, motor sheave, blower sheave and belt. Make sure wires are not pinched and not over sharp edges.

Adjust motor downward to tighten belt. Raise or lower motor slide assembly with adjusting bolt and retighten

2 slide nuts. Check for correct tension (See Tensioning

V-Belt Drives page). Rewire motor (at contactor) for correct rotation. Spin blower wheel to ensure wheel is not obstructed.

8. Replace 2 panels.

Back to Side Discharge Conversion - If the discharge is changed from back to side, use above instruction noting that illustrations will be reversed.

Left vs. Right Return - It is not possible to fi eld convert return air between left or right return models due to the necessity of refrigeration copper piping changes.

However, the conversion process of side to back or back to side discharge for either right or left return confi guration is the same. In some cases, it may be possible to rotate the entire unit 180 degrees if the return air connection needs to be on the opposite side.

Note that rotating the unit will move the piping to the other end of the unit.

Horizontal Units Condensate Piping - Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. Insure that unit pitch does not cause condensate leaks inside the cabinet.

Install condensate trap at each unit with the top of the trap positioned below the unit condensate drain connection as shown in Figure 6.

Each unit must be installed with its own individual trap and connection to the condensate line (main) or riser. Provide a means to fl ush or blow out the condensate line. DO NOT install units with a common trap and/or vent.

Always vent the condensate line when dirt or air can collect in the line or a long horizontal drain line is required. Also vent when large units are working against higher external static pressure than other units connected to the same condensate main since this may cause poor drainage for all units on the line. WHEN A

VENT IS INSTALLED IN THE DRAIN LINE, IT MUST BE

LOCATED AFTER THE TRAP IN THE DIRECTION OF

Duct System Installation - Proper duct sizing and design is critical to the performance of the unit. The duct system should be designed to allow adequate and even airfl ow through the unit during operation.

Air fl ow through the unit MUST be at or above the minimum stated airfl ow for the unit to avoid equipment damage. Duct systems should be designed for quiet operation. Refer to Figure 3 for horizontal duct system details or Figure 8 for vertical duct system details. A fl exible connector is recommended for both discharge and return air duct connections on metal duct systems to eliminate the transfer of vibration to the duct system. To maximize sound attenuation of the unit blower, the supply and return plenums should include internal fi berglass duct liner or be constructed from ductboard for the fi rst few feet. Application of the unit to uninsulated ductwork in an unconditioned space is not recommended, as the unit’s performance may be adversely affected.

At least one 90° elbow should be included in the supply duct to reduce air noise. If air noise or excessive air fl ow is a problem, the blower speed can be changed. For airfl ow charts, consult submittal data for the series and model of the specifi c unit.

If the unit is connected to existing ductwork, a previous check should have been made to ensure that the ductwork has the capacity to handle the airfl ow required for the unit. If ducting is too small, as in the replacement of a heating only system, larger ductwork should be installed. All existing ductwork should be checked for leaks and repaired as necessary.

Vertical Location and Access

TC units are not designed for outdoor installation.

Locate the unit in an indoor area that allows enough space for installation and for service personnel to perform typical maintenance or repairs. TC units are typically installed in a fl oor level closet or in a small mechanical room. Refer to Figure 7 for an illustration of a typical installation. Install units with adequate clearance to allow maintenance and servicing. Conform to the following guidelines when selecting unit location:

• Provide adequate clearance for filter replacement and drain pan cleaning. DO NOT block filter access with piping, conduit or other materials. Refer to submittal drawing for Vertical Unit Dimensions.

• Provide access for fan and fan motor maintenance and for servicing of the compressor and coils without removal of the unit.

• Provide an unobstructed path to the unit within the closet or mechanical room to enable removal of the unit if necessary.

• Provide access to water valves and fittings, and screwdriver access to the unit side panels, discharge collar and all electrical connections

Duct System Design & Installation Guidelines

The following application guidelines must be used when installing TC units. Failure to follow these guidelines could result in unsatisfactory unit performance and/or premature failure of some unit components.

ClimateMaster will not warrant, or accept responsibility for products which fail, have defects, damage or insuffi cient performance as a result of improper application.

• The duct system must be sized to handle the airflow quietly and must not exceed the maximum allowable External Static Pressure. To maximize sound attenuation metal supply and return ducts should include internal insulation or be of duct board construction for the first 10 feet or end of first full-sized elbow.

• Install a flexible connector in all supply and return air ducts close to the unit to inhibit sound transfer to the ducts.

• Do not install uninsulated duct in an unconditioned space. The unit performance will be adversely affected and damage from condensate can occur. c l i m a t e m a s t e r. c o m 17

Repair any leaks.

• On units with multiple fan outlets a “pair of pants” duct connection must be used for proper air balance and distribution and to prevent fan oscillation.

• Include at least one 90-degree turn in supply air ducts to reduce noise transmission.

• Existing ducts must be checked to ensure proper size and configuration prior to installation of any replacement unit. Also inspect for and repair all air leaks in existing ducts.

• Units may only be connected to a dedicated duct system. Consult the factory BEFORE connecting multiple units to a common duct system.

• Never connect a unit to a duct system with automatic or modulating dampers, VAV boxes, etc. in the supply air system. Never allow a situation where the total unit

CFM can drop below the minimum required for proper unit operation.

• Never connect a bypass damper from the supply air duct to the return air duct. Never allow the return air temperature to drop below the minimum allowable normal temperature for proper unit operation.

• Do not use TC units for 100% outdoor air treatment.

Do not add hot-gas-bypass to “convert” a unit for outdoor air treatment. Always use a dedicated outdoor air unit for outdoor air treatment.

• Do not exceed 10% of the total unit CFM with untreated outdoor air.

Piping Installation

Installation of Supply and Return Piping

Follow these piping guidelines.

1. Install a drain valve at the base of each supply and return riser to facilitate system fl ushing.

2. Install shut-off / balancing valves and unions at each unit to permit unit removal for servicing.

3. Place strainers at the inlet of each system circulating pump.

4. Select the proper hose length to allow slack between connection points. Hoses may vary in length by +2% to -4% under pressure.

5. Refer to Table 1. Do not exceed the minimum bend radius for the hose selected. Exceeding the minimum bend radius may cause the hose to collapse, which reduces water fl ow rate. Install an angle adapter to avoid sharp bends in the hose when the radius falls below the required minimum.

WARNING! Polyolester Oil, commonly known as POE oil, is a synthetic oil used in many refrigeration systems including those with HFC-410A refrigerant. POE oil, if it ever comes in contact with PVC or CPVC 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.

WARNING!

CAUTION!

CAUTION! Corrosive system water requires corrosion resistant fi ttings and hoses, and may require water treatment.

CAUTION!

CAUTION! 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, outside the building or when the loop water temperature is below the minimum expected dew point of the pipe ambient conditions. Insulation is required if loop water temperature drops below the dew point (insulation is required for ground loop applications in most climates).

CAUTION!

CAUTION! Piping must comply with all applicable codes.

Pipe joint compound is not necessary when Tefl on ® thread tape is pre-applied to hose assemblies or when fl ared-end connections are used. If pipe joint compound is preferred, use compound only in small amounts on the external pipe threads of the fi tting adapters. Prevent sealant from reaching the fl ared surfaces of the joint.

Maximum allowable torque for brass fi ttings is 41 N-m.

If a torque wrench is not available, tighten fi nger-tight plus one quarter turn. Tighten steel fi ttings as necessary.

NOTICE! Do not allow hoses to rest against structural building components. Compressor vibration may be transmitted through the hoses to the structure, causing unnecessary noise complaints.

Water-Loop Heat Pump Applications

Commercial Water Loop Applications -

Commercial systems typically include a number of units connected 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 10°C, 13mm closed cell insulation is required on all piping surfaces to eliminate condensation (extended range units required). Metal to plastic threaded joints should never be used due to their tendency to leak over time. All commercial class units include low temperature-soldered bracket-supported IPT water connections, which do not require a backup wrench.

Balancing valves and an external low pressure drop solenoid valve for use in variable speed pumping systems may also be included in the hose kit.

The piping system should be fl ushed to remove dirt, piping chips, and other foreign material prior to operation (see “Piping System Cleaning and

Flushing Procedures” in this manual). The fl ow rate is usually set between 2.9 and 4.5 l/m per kW of cooling capacity. ClimateMaster recommends 3.9 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 fl ow verifi cation, as well as performance checks.

Tefl on tape thread sealant is recommended to minimize internal fouling of the heat exchanger. Do not over tighten connections and route piping so as not to interfere with service or maintenance access. Hose kits are available from ClimateMaster in different confi gurations as shown in Figure 8 for connection between the unit and the piping system. Depending upon selection, hose kits may include shut off valves,

P/T plugs for performance measurement, high pressure stainless steel braided hose, “Y” type strainer with blow down valve, and/or “J” type swivel connection.

Water loop heat pump (cooling tower/boiler) systems typically utilize a common loop, maintained between 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 fi ltering will be necessary.

State/provincial 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.

CAUTION!

CAUTION! Ground loop applications require extended range equipment and optional refrigerant/water circuit insulation.

Flushing the Earth Loop - Upon completion of system installation and testing, fl ush the system to remove all foreign objects and purge to remove all air.

Antifreeze - In areas where minimum entering loop temperatures drop below 5°C or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze; however your local sales manager should be consulted for the antifreeze best suited to your area.

Low temperature protection should be maintained to 9°C below the lowest expected entering loop temperature. For example, if -1°C is the minimum expected entering loop temperature, the leaving loop temperature would be -4 to -6°C and low temperature protection should be at -10°C. Calculation is as follows:

-1°C - 9°C = -10°C. 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.

All alcohols should be premixed and pumped from a reservoir outside of the building when possible or introduced under the water level to prevent fumes.

Calculate the total volume of fl uid in the piping system.

Then use the percentage by volume shown in table

2 for the amount of antifreeze needed. Antifreeze concentration should be checked from a well mixed sample using a hydrometer to measure specifi c gravity.

Piping Installation - The typical closed loop ground source system is shown in Figure 9. All earth loop piping materials should be limited to polyethylene fusion only for in-ground sections of the loop.

Galvanized or steel fi ttings should not be used at any time due to their tendency to corrode. All plastic to metal threaded fi ttings should be avoided due to their potential to leak in earth coupled applications.

A fl anged fi tting should be substituted. P/T plugs should be used so that fl ow can be measured using the pressure drop of the unit heat exchanger.

Low Water Temperature Cutout Setting

CXM - When antifreeze is selected, the FP1 jumper

(JW3) should be clipped to select the low temperature

(antifreeze -12.2°C) setpoint and avoid nuisance faults

(see “Low Water Temperature Cutout Selection” in this manual). Note: Low water temperature operation requires extended range equipment.

Earth loop temperatures can range between -4 to 43°C. Flow rates between 2.41 to 3.23 l/m per kW of cooling capacity is recommended in these applications. Test individual horizontal loop circuits before backfi lling. Test vertical U-bends and pond loop assemblies prior to installation. Pressures of at least 689 kPa should be used when testing. Do not exceed the pipe pressure rating. Test entire system when all loops are assembled.

Open Loop - Ground Water Systems - Typical open loop piping is shown in Figure 10. Shut off valves should be included for ease of servicing. Boiler drains or other valves should be “tee’d” into the lines to allow acid fl ushing of the heat exchanger. Shut off valves should be positioned to allow fl ow through the coax via the boiler drains without allowing fl ow into the piping system. P/T plugs should be used so that pressure drop and temperature can be measured.

WARNING!


plan should be implemented in these probable scaling situations. Other water quality issues such as iron fouling, corrosion prevention and erosion and clogging should be referenced in Table 3.

Expansion Tank and Pump Use a closed, bladdertype expansion tank to minimize mineral formation due to air exposure. The expansion tank should be sized to provide at least one minute continuous run time of the pump using its drawdown capacity rating to prevent pump short cycling. Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local building codes

(e.g. recharge well, storm sewer, drain fi eld, 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 quantity should be plentiful and of good quality.

Consult table 3 for water quality guidelines. The unit can be ordered with either a copper or cupronickel water heat exchanger. Consult Table 3 for recommendations. Copper is recommended for closed loop systems and open loop ground water systems that are not high in mineral content or corrosiveness.

In conditions anticipating heavy scale formation or in brackish water, a cupro-nickel heat exchanger is recommended. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, an open loop system is not recommended. Heat exchanger coils may over time lose heat exchange capabilities due to build up of mineral deposits. Heat exchangers must only be serviced by a qualifi ed technician, as acid and special pumping equipment is required.

Desuperheater coils can likewise become scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional acid fl ushing. In some cases, the desuperheater option should not be recommended due to hard water conditions and additional maintenance required.

Water Quality Standards Table 3 should be consulted for water quality requirements. Scaling potential should be assessed using the pH/Calcium hardness method. If the pH <7.5 and the calcium hardness is less than 100 ppm, scaling potential is low.

If this method yields numbers out of range of those listed, the Ryznar Stability and Langelier Saturation indecies should be calculated. Use the appropriate scaling surface temperature for the application,

66°C for direct use (well water/open loop) and DHW

(desuperheater); 32°C for indirect use. A monitoring

Water Control Valve - Note the placement of the water control valve in Figure 10. Always maintain water pressure in the heat exchanger by placing the water control valve(s) on the discharge line to prevent mineral precipitation during the off-cycle. Pilot operated 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, a slow closing valve can draw up to 35VA.

This can overload smaller 40 or 50 VA transformers depending on the other controls in the circuit. A typical pilot operated solenoid valve draws approximately

15VA (see Figure 14). Note the special wiring diagrams for slow closing valves (Figures 15 & 16).

Flow Regulation - Flow regulation can be accomplished by two methods. One method of fl ow regulation involves simply adjusting the ball valve or water control valve on the discharge line. Measure the pressure drop through the unit heat exchanger, and determine fl ow rate from Tables 8a through 8e. Since the pressure is constantly varying, two pressure gauges may be needed. Adjust the valve until the desired fl ow of 2.0 to 2.6 l/m per kW is achieved. A second method of fl ow control requires a fl ow control device mounted on the outlet of the water control valve. The device is typically a brass fi tting with an orifi ce of rubber or plastic material that is designed to allow a specifi ed fl ow rate. On occasion, fl ow control devices may produce velocity noise that can be reduced by applying some back pressure from the ball valve located on the discharge line. Slightly closing the valve will spread the pressure drop over both devices, lessening the velocity noise. NOTE: When EWT is below 10°C, 2.6 l/m per kW is required.

Water Coil Low Temperature Limit Setting - For all open loop systems the -1.1°C FP1 setting (factory settingwater) should be used to avoid freeze damage to the unit. See “Low Water Temperature Cutout Selection” in this manual for details on the low limit setting.

The ClimateMaster Water Quality Table provides water quality requirements for ClimateMaster coaxial heat exchangers. The water should be evaluated by an independent testing facility comparing to this Table and when properties are outside of these requirements, an external secondary heat exchanger must be used to isolate the heat pump heat exchanger from the unsuitable water. Failure to do so will void the warranty for the coaxial heat exchanger and any other components damaged by a leak.

• Closed Recirculating system is identified by a closed pressurized piping system.

• Recirculating open wells should observe the open recirculating design considerations.

• NR - Application not recommended.

Electrical - Power & Low Voltage Wiring


Thermostat Connections - The thermostat should be wired directly to the CXM or DXM board. Figure 12 shows wiring for TC units. See

“Electrical – Thermostat” (Figure 16) for specifi c terminal connections. Review the appropriate AOM

(Application, Operation and Maintenance) manual for units with DDC controls.

Low Water Temperature Cutout Selection - The CXM/

DXM control allows the fi eld selection of low water (or water-antifreeze solution) temperature limit by clipping jumper JW3, which changes the sensing temperature associated with thermistor FP1. Note that the FP1 thermistor is located on the refrigerant line between the coaxial heat exchanger and expansion device (TXV or cap tube). Therefore, FP1 is sensing refrigerant temperature, not water temperature, which is a better indication of how water fl ow rate/temperature is affecting the refrigeration circuit.

The factory setting for FP1 is for systems using water -1.1°C refrigerant temperature). In low water temperature (extended range) applications with antifreeze (most ground loops), jumper JW3 should be clipped as shown in Figure 13 to change the setting to -12.2°C refrigerant temperature, a more suitable temperature when using an antifreeze solution. All

ClimateMaster units operating with entering water temperatures below 15°C must include the optional water/refrigerant circuit insulation package to prevent internal condensation.

CAUTION!

CAUTION!

Many units are installed with a factory or fi eld supplied manual or electric shut-off valve. DAMAGE WILL

OCCUR if shut-off valve is closed during unit operation. A high pressure switch must be installed on the heat pump side of any fi eld provided shut-off valves and connected to the heat pump controls in series with the built-in refrigerant circuit high pressure switch to disable compressor operation if water pressure exceeds pressure switch setting. The fi eld installed high pressure switch shall have a cut-out pressure of 2068 kPa and a cut-in pressure of 1723 kPa. This pressure switch can be ordered from ClimateMaster with a

1/4” internal fl are connection as part number 39B0005N02.

Thermostat

Water Solenoid Valves - An external solenoid valve(s) should be used on ground water installations to shut off fl ow to the unit when the compressor is not operating. A slow closing valve may be required to help reduce water hammer. Figure 14 shows typical wiring for a 24VAC external solenoid valve. This wiring should only be used if valve fully opens in 15 second. Figure 15 illustrates a typical slow closing water control valve wiring for

Belimo valves. Slow closing valves take approximately

60 seconds to open (very little water will fl ow before 45 seconds). Once fully open, an end switch allows the compressor to be energized. Only relay or triac based electronic thermostats should be used with slow closing valves. When wired as shown, the slow closing valve will operate properly with the following notations:

1. The valve will remain open during a unit lockout.

2. The valve will draw approximately 25-35 VA through the “Y” signal of the thermostat.

Note: This valve can overheat the anticipator of an electromechanical thermostat. Therefore, only relay or triac based thermostats should be used.




R e v i s e d : 2 5 J u l y, 2 0 1 7

Electrical - Thermostat Wiring

Thermostat Installation - The thermostat should be located on an interior wall in a larger room, away from supply duct drafts. DO NOT locate the thermostat in areas subject to sunlight, drafts or on external walls.

The wire access hole behind the thermostat may in certain cases need to be sealed to prevent erroneous temperature measurement. Position the thermostat back plate against the wall so that it appears level and so the thermostat wires protrude through the middle of the back plate. Mark the position of the back plate mounting holes and drill holes with a 3/16” (5mm) bit. Install supplied anchors and secure plate to the wall. Thermostat wire must be 18 AWG wire. Wire the appropriate thermostat as shown in Figure 16 to the low voltage terminal strip on the CXM or DXM control board. Practically any heat pump thermostat will work with ClimateMaster units, provided it has the correct number of heating and cooling stages.

Maintenance (AOM) manual (part # 97B0003N12 or part

#97B0003N13).

Field Selectable Inputs the service technician to check the operation of the control in a timely manner. By momentarily shorting the test terminals, the CXM control enters a 20 minute test mode period in which all time delays are sped up 15 times. Upon entering test mode, the status

LED will fl ash a code representing the last fault. For diagnostic ease at the thermostat, the alarm relay will also cycle during test mode. The alarm relay will cycle on and off similar to the status LED to indicate a code representing the last fault, at the thermostat. Test mode can be exited by shorting the test terminals for 3 seconds.

Retry Mode: If the control is attempting a retry of a fault, the status LED will slow fl ash (slow fl ash = one fl ash every 2 seconds) to indicate the control is in the process of retrying.

Field Selectable Inputs Test mode: Test mode allows the service technician to check the operation of the control in a timely manner. By momentarily shorting the test terminals, the DXM control enters a 20 minute test mode period in which all time delays are sped up 15 times. Upon entering test mode, the status

LED will fl ash a code representing the last fault. For diagnostic ease at the thermostat, the alarm relay will also cycle during test mode. The alarm relay will cycle on and off similar to the status LED to indicate a code representing the last fault, at the thermostat. Test mode can be exited by shorting the test terminals for 3 seconds.

Retry mode: If the control is attempting a retry of a fault, the status LED will slow fl ash (slow fl ash = one fl ash every 2 seconds) to indicate the control is in the process of retrying.

Field Confi guration Options - Note: In the following fi eld confi guration options, jumper wires should be clipped ONLY when power is removed from the

DXM control.

DIP Switches - Note: In the following fi eld confi guration options, DIP switches should only be changed when power is removed from the DXM control.

DIP Package #1 (S1) -

1.1 feature.

1.2 -

DIP Package #1 has 8 switches and provides the following setup selections:

- Unit Performance Sentinel (UPS) disable: DIP

Switch 1.1 provides fi eld selection to disable the UPS

On = Enabled. Off = Disabled.

Compressor relay staging operation: DIP 1.2 provides selection of compressor relay staging operation. The compressor relay can be selected to turn on with a stage 1 or stage 2 call from the thermostat. This is used with dual stage units (2 compressors where 2 DXM controls are being used) or with master/slave applications. In master/slave applications, each compressor and fan will stage according to its appropriate DIP 1.2 setting. If set to stage 2, the compressor will have a 3 second on-delay before energizing during a Stage 2 demand. Also, if set for stage 2, the alarm relay will NOT cycle during test mode.On = Stage 1. Off = Stage 2.

1.3 - Thermostat type (heat pump or heat/cool): DIP

1.3 provides selection of thermostat type. Heat pump or heat/cool thermostats can be selected. When in heat/cool mode, Y1 is the input call for cooling stage

1; Y2 is the input call for cooling stage 2; W1 is the input call for heating stage 1; and O/W2 is the input call for heating stage 2. In heat pump mode, Y1 is the c l i m a t e m a s t e r. c o m 45

input call for compressor stage 1; Y2 is the input call for compressor stage 2; W1 is the input call for heating stage 3 or emergency heat; and O/W2 is the input call for reversing valve (heating or cooling, depending upon DIP 1.4).

On = Heat Pump. Off = Heat/Cool.

1.4 Thermostat type (O/B): DIP 1.4 provides selection of thermostat type for reversing valve activation. Heat pump thermostats with “O” output (reversing valve energized for cooling) or “B” output (reversing valve energized for heating) can be selected with DIP 1.4.

On = HP stat with “O” output for cooling. Off = HP stat with “B” output for heating.

1.5 Dehumidifi cation mode: DIP 1.5 provides selection of normal or dehumidifi cation fan mode. In dehumidifi cation mode, the fan speed relay will remain off during cooling stage 2. In normal mode, the fan speed relay will turn on during cooling stage 2.

On = Normal fan mode. Off = Dehumidifi cation mode.

1.6 DDC output at EH2: DIP 1.6 provides selection for DDC operation. If set to “DDC Output at EH2,” the EH2 terminal will continuously output the last fault code of the controller. If set to “EH2 normal,” EH2 will operate as standard electric heat output.

On = EH2 Normal. Off = DDC Output at EH2.

1.7 Boilerless operation: DIP 1.7 provides selection of boilerless operation. In boilerless mode, the compressor is only used for heating when FP1 is above the temperature specifi ed by the setting of DIP 1.8.

Below DIP 1.8 setting, the compressor is not used and the control goes into emergency heat mode, staging on EH1 and EH2 to provide heating.

On = normal. Off = Boilerless operation.

1.8 Boilerless changeover temperature: DIP

1.8 provides selection of boilerless changeover temperature setpoint. Note that the FP1 thermistor is sensing refrigerant temperature between the coaxial heat exchanger and the expansion device (TXV).

Therefore, the 10°C setting is not 10°C water, but approximately 16°C EWT.

On = 10°C. Off = 16°C.

DIP Package #2 (S2) DIP Package #2 has 8 switches and provides the following setup selections:

2.1 Accessory1 relay personality: DIP 2.1 provides selection of ACC1 relay personality (relay operation/ characteristics). See table 6c for description of functionality.

2.2 - Accessory1 relay personality: DIP 2.2 provides selection of ACC 1 relay personality (relay operation/ characteristics). See table 6c for description of functionality.

2.3 Accessory1 relay personality: DIP 2.3 provides selection of ACC 1 relay options. See table 6c for description of functionality.

2.4 - Accessory2 relay personality: DIP 2.4 provides selection of ACC 2 relay personality (relay operation/ characteristics). See table 6c for description of functionality.

2.5 Accessory2 relay personality: DIP 2.5 provides selection of ACC 2 relay personality (relay operation/ characteristics). See table 6c for description of functionality.

2.6 Accessory2 relay personality: DIP 2.6 provides selection of ACC 2 relay options. See table 6c for description of functionality.

2.7 Auto dehumidifi cation fan mode or high fan mode: DIP 2.7 provides selection of auto dehumidifi cation fan mode or high fan mode. In auto dehumidifi cation mode, the fan speed relay will remain off during cooling stage 2 IF the H input is active. In high fan mode, the fan enable and fan speed relays will turn on when the H input is active.

On = Auto dehumidifi cation mode. Off = High fan mode.

2.8 Special factory selection: DIP 2.8 provides special factory selection. Normal position is “On”.

Do not change selection unless instructed to do so by the factory.

Safety Features

Safety Features – CXM/DXM Control

The safety features below are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions.

Anti-short cycle protection: The control features a 5 minute anti-short cycle protection for the compressor.

Note: The 5 minute anti-short cycle also occurs at power up.

Random start: The control features a random start upon power up of 5-80 seconds.

Fault Retry: In Fault Retry mode, the Status LED begins slowly fl ashing to signal that the control is trying to recover from a fault input. The control will stage off the outputs and then “try again” to satisfy the thermostat input call. Once the thermostat input call is satisfi ed, the control will continue on as if no fault occurred.

If 3 consecutive faults occur without satisfying the thermostat input call, the control will go into “lockout” mode. The last fault causing the lockout will be stored in memory and can be viewed at the “fault” LED (DXM board) or by going into test mode (CXM board). Note:

FP1/FP2 faults are factory set at only one try.

Low pressure switch: The low pressure switch must be open and remain open for 30 continuous seconds during

“on” cycle to be recognized as a low pressure fault. If the low pressure switch is open for 30 seconds prior to compressor power up it will be considered a low pressure

(loss of charge) fault. The low pressure switch input is bypassed for the initial 120 seconds of a compressor run cycle.

Low pressure lockout code = 3

Water coil low temperature (FP1): The FP1 thermistor temperature must be below the selected low temperature limit setting for 30 continuous seconds during a compressor run cycle to be recognized as a

FP1 fault. The FP1 input is bypassed for the initial 120 seconds of a compressor run cycle. FP1 is set at the factory for one try. Therefore, the control will go into lockout mode once the FP1 fault has occurred.

FP1 lockout code = 4

Lockout: In lockout mode, the status LED will begin fast fl ashing. The compressor relay is turned off immediately. Lockout mode can be “soft” reset by turning off the thermostat (or satisfying the call). A

“soft” reset keeps the fault in memory but resets the control. A “hard” reset (disconnecting power to the control) resets the control and erases fault memory.

Lockout with emergency heat: occur. If DXM is confi gured for heat pump thermostat type (DIP 1.3), emergency heat will become active if O/

W2 is energized.

While in lockout mode, if W becomes active (CXM), emergency heat mode will

Air coil low temperature (FP2): The FP2 thermistor temperature must be below the selected low temperature limit setting for 30 continuous seconds during a compressor run cycle to be recognized as a

FP2 fault. The FP2 input is bypassed for the initial 60 seconds of a compressor run cycle. FP2 is set at the factory for one try. Therefore, the control will go into lockout mode once the FP2 fault has occurred.

FP2 lockout code = 5

Condensate overfl ow: The condensate overfl ow sensor must sense overfl ow level for 30 continuous seconds to be recognized as a CO fault. Condensate overfl ow will be monitored at all times.

CO lockout code = 6

High pressure switch: When the high pressure switch opens due to high refrigerant pressures, the compressor relay is de-energized immediately since the high pressure switch is in series with the compressor contactor coil. The high pressure fault recognition is immediate (does not delay for 30 continuous seconds before de-energizing the compressor).

High pressure lockout code = 2

Example: 2 quick fl ashes, 10 sec pause, 2 quick fl ashes,

10 sec. pause, etc.

Over/under voltage shutdown: An over/under voltage condition exists when the control voltage is outside the range of 19VAC to 30VAC. Over/under voltage shut down is a self-resetting safety. If the voltage comes back within range for at least 0.5 seconds, normal operation is restored. This is not considered a fault or lockout. If the CXM/DXM is in over/under voltage shutdown for 15 minutes, the alarm relay will close.

Over/under voltage shut down code = 7 c l i m a t e m a s t e r. c o m 47



R e v i s e d : 2 5 J u l y, 2 0 1 7

CXM and DXM Controls

Unit Performance Sentinel-UPS (patent pending): The

UPS feature indicates when the heat pump is operating ineffi ciently. A UPS condition exists when: a) In heating mode with compressor energized, FP2 is greater than 52°C for 30 continuous seconds, or: b) In cooling mode with compressor energized, FP1 is greater than 52°C for 30 continuous seconds, or: c) In cooling mode with compressor energized, FP2 is less than 4.5°C for 30 continuous seconds.

If a UPS condition occurs, the control will immediately go to UPS warning. The status LED will remain on as if the control is in normal mode. Outputs of the control, excluding LED and alarm relay, will NOT be affected by UPS. The UPS condition cannot occur during a compressor off cycle. During UPS warning, the alarm relay will cycle on and off. The cycle rate will be “on” for 5 seconds, “off” for 25 seconds, “on” for 5 seconds,

“off” for 25 seconds, etc.

UPS warning code = 8

Swapped FP1/FP2 thermistors: During test mode, the control monitors to see if the FP1 and FP2 thermistors are in the appropriate places. If the control is in test mode, the control will lockout with code 9 after 30 seconds if: a) The compressor is on in the cooling mode and the

FP1 sensor is colder than the FP2 sensor, or: b) The compressor is on in the heating mode and the

FP2 sensor is colder than the FP1 sensor.

Swapped FP1/FP2 thermistor code = 9.

ESD (DXM only): The ESD (Emergency Shut Down) mode can be enabled from an external common signal to terminal ESD to shut down the unit. The green status light will fl ash code 3 when the unit is in ESD mode.

ESD mode = code 3 (green “status” LED)

Diagnostic Features The LED on the CXM board advises the technician of the current status of the CXM control. The LED can display either the current CXM mode or the last fault in memory if in test mode. If there is no fault in memory, the LED will fl ash Code 1

(when in test mode).

The green status LED and red fault LED on the DXM board advise the technician of the current status of the

DXM control. The status LED will indicate the current mode that the DXM control is in. The fault LED will

ALWAYS fl ash a code representing the LAST fault in memory. If there is no fault in memory, the fault LED will fl ash Code 1. The yellow test LED will turn on when in test mode. CAUTION: Do not restart units without inspection and remedy of faulting condition. Damage may occur.

CXM/DXM Control Start-up Operation The control will not operate until all inputs and safety controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at power-up.

The fi rst time after power-up that there is a call for compressor, the compressor will follow a 5 to 80 second random start delay. After the random start delay and anti-short cycle delay, the compressor relay will be energized. On all subsequent compressor calls, the random start delay is omitted.

Blower Adjustment

CAUTION!

CAUTION! Always disconnect all power supply(s) to unit prior to making belt or sheave adjustments. Inadvertently starting of the motor can cause damage to the equipment and personal injury.

Airfl ow and External Static Pressure

Selection Adjustment - The TCH/V Series is available with standard, low, and high static options. These options will substitute a different blower drive sheave for each static range. In addition certain static ranges

(bold print in Tables 5a through 5k) may require the optional large fan motor. Please specify static range and motor horsepower when ordering. See model nomenclature.

Belt Tensioning Procedure - TCH/V

1. Remove belt from motor sheave

2. Lift motor assembly

3. Loosen the 7.9mm hex nuts on the grommet motor adjustment bolts (2 per bolt). To increase the belt tension loosen the top hex nut. To decrease the belt tension loosen the bottom hex nut.

4. Turn the bolts by hand to the desired position then tighten the 7.9mm hex nuts ( 2 per bolt).

5. Lower the motor assembly

6. Install the belt

7. The belt should be tensioned tensioning gauge method such as the Browning Belt Tensioner to set proper belt tension (See next page) .

Sheave Adjustment - The TCH/V Series is supplied with variable sheave drive on the fan motor to adjust for differing airfl ows at various ESP conditions. Select an airfl ow requirement on the left side of the table, then move horizontally to right under the required ESP.

Note the sheave turns open, rpm and horsepower for that condition. Fully closed the sheave will produce the highest static capability (higher rpm). To adjust sheave position: loosen belt tension and remove belt, loosen set screw on variable sheave (on fan motor) and open sheave to desired position. Retighten set screw and replace belt and set belt tension as below.

Notes:

- Motor position should not need adjustment.

- Motor sheave position is at mid position of each sheave. Thus the motor sheave is typically 2.5 turns open on a 5 turn sheave.

Sheave and Pulley Alignment - Verify belt is straight, misalignment will cause premature belt failure. Adjust sheave if needed.

Belt Tensioning - An overly loose belt will, upon motor start, produce a slippage 'squeel' and cause premature belt failure and or intermittent airfl ow. An overly tight belt can cause premature motor or blower bearing failure. c l i m a t e m a s t e r. c o m 49

Tensioning V-Belt Drives

General Rules of Tensioning

1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.

2. Check tension frequently during the first 24-48 hours of operation.

3. Over tensioning shortens belt and bearing life.

4. Keep belts free from foreign material which may cause slip.

5. Make V-drive inspection on periodic basis. Tension when slipping.

Never apply belt dressing as this willl damage the belt and cause

Tension Measurement Procedure

1. Measure the belt span (see sketch).

2. Position bottom of the large “O” ring on the span scale at the measured belt span.

3. Set the small “O” ring on the deflection force scale to zero.

4. Place the tension checker squarely on one belt at the center of the belt span. Apply a force on the plunger and perpendicular to the belt span until the bottom of the large “O” ring is even with the top of the next belt or with the bottom of a straight edge laid across the sheaves.

5. Remove the tension checker and read the forct applied from the bottom of the small “O” ring on the deflection force scale.

6. Compare the force you have applied with the values given in the table below. The force should be between the minimum and maximum shown. The maximum value is shown for “New Belt” and new belts should be tensioned at this value to allow for expected tension loss. Used belts should be maintained at the minimum value as indicated in the table below.

Operating Conditions

Environment – Units are designed for indoor installation only. Never install units in areas subject to freezing or where humidity levels could cause cabinet condensation

(such as unconditioned spaces subject to 100% outside air).

Power Supply – A voltage variation of +/– 10% of nameplate utilization voltage is acceptable.

Determination of operating limits is dependent primarily upon three factors: 1) return air temperature. 2) water temperature, and 3) ambient temperature. When any one of these factors is at minimum or maximum levels, the other two factors should be at normal levels to ensure proper unit operation. Extreme variations in temperature and humidity and/or corrosive water or air will adversely affect unit performance, reliability, and service life. Consult Table 9a for operating limits.

Comissioning Conditions

Starting conditions are based upon the following notes:

Notes:

1. Conditions in Table 9b are not normal or continuous operating conditions. Minimum/maximum limits are start-up conditions to bring the building space up to occupancy temperatures. Units are not designed to operate under these conditions on a regular basis.

2. Voltage utilization range complies with AHRI

Standard 110.

Piping System Cleaning and Flushing

Piping System Cleaning and Flushing - Cleaning and fl ushing the WLHP piping system is the single most important step to ensure proper start-up and continued effi cient operation of the system.

Follow the instructions below to properly clean and fl ush the system:

1. Ensure that 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 fl exible hose.

3. Open all air vents. Fill the system with water. DO NOT allow system to overfl ow. Bleed all air from the system.

Pressurize and check the system for leaks and repair as appropriate. ClimaDry ® -equipped units have a manual air bleed valve at the top of the reheat coil. This valve must be used to bleed the air from the reheat coil after fi lling the system, for ClimaDry ® to operate properly.

4. Verify that all strainers are in place (ClimateMaster recommends a strainer with a #20 stainless steel wire mesh). Start the pumps, and systematically check each vent to ensure that all air is bled from the system.

5. Verify that make-up water is available. Adjust make-up water as required to replace the air which was bled from the system. Check and adjust the water/air level in the expansion tank.

6. Set the boiler to raise the loop temperature to approximately 86°F [30°C]. Open a drain at the lowest point in the system. Adjust the make-up water replacement rate to equal the rate of bleed.

7. Refi ll the system and add trisodium phosphate in a proportion of approximately 150 gallons [1/2 kg per 750 l] of water (or other equivalent approved cleaning agent).

Reset the boiler to raise the loop temperature to 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 the connections to each of the units.

Refi ll the system and bleed off all air.

9. Test the system pH with litmus paper. The system water should be in the range of pH 6.0 - 8.5 (see table 3). Add chemicals, as appropriate to maintain neutral pH levels.

10. When the system is successfully cleaned, fl ushed, refi lled and bled, check the main system panels, safety cutouts and alarms. Set the controls to properly maintain loop temperatures.

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 fi nishing 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.

DO NOT use “Stop Leak” or similar chemical agent in this system. Addition of chemicals of this type to the loop water will foul the heat exchanger and inhibit unit operation.

WARNING!


BEFORE POWERING SYSTEM, please check the following:

UNIT CHECKOUT

Line voltage and wiring: Verify that voltage is within an acceptable range for the unit and wiring and fuses/breakers are properly sized. Verify that low voltage wiring is complete.

Unit control transformer: Ensure that transformer has the properly selected voltage tap. Commercial

380-420V units are factory wired for 380V operation unless specifi ed otherwise .

Balancing/shutoff valves: Ensure that all isolation valves are open (after system fl ushing - see System

Checkout) and water control valves are wired.

Entering water and air: Ensure that entering water and air temperatures are within operating limits of

Table 9.

Low water temperature cutout: Verify that low water temperature cut-out on the CXM/DXM control is properly set.

Unit blower wheel: Manually rotate blower wheel to verify free rotation and ensure that all blower wheels are secured to the blower motor shaft and centered in housing.

Blower motor: Verify motor bolts are tight. DO

NOT oil motors upon start-up. Fan motors are preoiled at the factory.

Check shaft pillow blocks, sheave and pulley are tight

Verify sheave has been set to turns in design requirement. Record turns on start up log sheet.

Verify belt is straight and proper tension

Condensate line: Verify that condensate line is open, trapped, vented and properly pitched toward drain.

Water fl ow balancing: Record inlet and outlet water temperatures for each heat pump upon startup.

This check can eliminate nuisance trip outs and high velocity water fl ow that could erode heat exchangers.

Unit air coil and fi lters: Ensure that fi lter is clean and accessible. Clean air coil of all manufacturing oils .

Unit controls: Verify that CXM or DXM fi eld selection options are properly set.


SYSTEM CHECKOUT

System water temperature: Check water temperature for proper range and also verify heating and cooling setpoints for proper operation.

System pH: Check and adjust water pH if necessary to maintain a level between 6 and 8.5. Proper pH promotes longevity of hoses and fi ttings

(see table 3).

System fl ushing: Verify that all hoses are connected end to end when fl ushing to ensure that debris bypasses the unit heat exchanger, water valves and other components. Water used in the system must be potable quality initially and clean of dirt, piping slag, and strong chemical cleaning agents.

Verify that all air is purged from the system. Air in the system can cause poor operation or system corrosion.

Cooling tower/boiler: Check equipment for proper setpoints and operation.

Standby pumps: Verify that the standby pump is properly installed and in operating condition.

System controls: Verify that system controls function and operate in the proper sequence.

Low water temperature cutout: Verify that low water temperature cut-out controls are provided for the outdoor portion of the loop. Otherwise, operating problems may occur.

System control center: Verify that the control center and alarm panel have appropriate setpoints and are operating as designed.

Miscellaneous: Note any questionable aspects of the installation.

CAUTION!

CAUTION! Verify that ALL water control valves are open and allow water fl ow prior to engaging the compressor.

Freezing of the coax or water lines can permanently damage the heat pump.

CAUTION!

CAUTION! To avoid equipment damage, DO NOT leave system fi lled in a building without heat during the winter unless antifreeze is added to the water loop. Heat exchangers never fully drain by themselves and will freeze unless winterized with antifreeze.

Unit Start-up Procedure

1. Turn the thermostat fan position to “ON”. Blower should start.

2. Balance air fl ow at registers.

3. Adjust all valves to their full open positions. Turn on the line power to all heat pumps.

4. Room temperature should be within the minimummaximum ranges of table 9. During start-up checks, loop water temperature entering the heat pump should be between 16°C and 35°C.

5. Two factors determine the operating limits of ClimateMaster heat pumps, (a) return air temperature, and (b) water temperature. When any one of these factors is at a minimum or maximum level, the other factor must be at normal level to insure proper unit operation.

a. Adjust the unit thermostat to the warmest setting. Place the thermostat mode switch in the

“COOL” position. Slowly reduce thermostat setting until the compressor activates.

b. Check for cool air delivery at the unit grille within a few minutes after the unit has begun to operate.

Note: Units have a fi ve minute time delay in the control circuit that can be eliminated on the

CXM/DXM control board as shown below in

Figure 28. See controls description for details.

c. Verify that the compressor is on and that the water fl ow rate is correct by measuring pressure drop through the heat exchanger using the P/T plugs and comparing to tables 10a through 10e.

d. Check the elevation and cleanliness of the condensate lines. Dripping may be a sign of a blocked line. Check that the condensate trap is fi lled to provide a water seal.

e. Check the temperature of both entering and leaving water. If temperature is within range table, proceed with the test. If temperature is outside of the operating range, check refrigerant pressures and compare to tables 12 through

15. Verify correct water fl ow by comparing unit pressure drop across the heat exchanger versus the data in tables 10a. Heat of rejection (HR) can be calculated and compared to submittal data capacity pages. The formula for HR for systems with water is as follows:

HR (kW) = TD x l/s x 4.18, where TD is the temperature difference between the entering and leaving water, and l/s is the fl ow rate, determined by comparing the pressure drop across the heat exchanger to tables 8a through

8e. f. Check air temperature drop across the air coil when compressor is operating. Air temperature drop should be between 8°C and 14°C.

g. Turn thermostat to “OFF” position. A hissing noise indicates proper functioning of the reversing valve.

6. Allow fi ve (5) minutes between tests for pressure to equalize before beginning heating test.

a. Adjust the thermostat to the lowest setting.

Place the thermostat mode switch in the

“HEAT” position.

b. Slowly raise the thermostat to a higher temperature until the compressor activates.

c. Check for warm air delivery within a few minutes after the unit has begun to operate.

d. Refer to table 17. Check the temperature of both entering and leaving water. If temperature is within range, proceed with the test. If temperature is outside of the operating range, check refrigerant pressures and compare to tables 11 through 16. Verify correct water fl ow by comparing unit pressure drop across the heat exchanger versus the data in tables 10a through

10e. Heat of extraction (HE) can be calculated and compared to submittal data capacity pages.

The formula for HE for systems with water is as follows:

HE (kW) = TD x l/s x 4.18, where TD is the temperature difference between the entering and leaving water, l/s is the fl ow rate, determined by comparing the pressure drop across the heat exchanger to tables 10a.

e. Check air temperature rise across the air coil when compressor is operating. Air temperature rise should be between 11°C and 17°C.

f. Check for vibration, noise, and water leaks.

7. If unit fails to operate, perform troubleshooting analysis (see troubleshooting section). If the check described fails to reveal the problem and the unit still does not operate, contact a trained service technician to insure proper diagnosis and repair of the equipment.

8. When testing is complete, set system to maintain desired comfort level.

9. . BE CERTAIN TO FILL OUT AND FORWARD

ALL WARRANTY REGISTRATION PAPERS TO

CLIMATEMASTER.

Note: If performance during any mode appears abnormal, refer to the CXM/DXM section or troubleshooting section of this manual. To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended.

CAUTION!

CAUTION! Verify that ALL water control valves are open and allow water fl ow prior to engaging the compressor.

Preventive Maintenance

Water Coil Maintenance -

(Direct ground water applications only)

If the system is installed in an area with a known high mineral content (125 P.P.M. or greater) in the water, it is best to establish a periodic maintenance schedule with the owner so the coil can be checked regularly. Consult the well water applications section of this manual for a more detailed water coil material selection. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with the heat exchanger material and copper water lines.

Generally, the more water fl owing through the unit, the less chance for scaling. Therefore,1.6 l/m per kW is recommended as a minimum fl ow. Minimum fl ow rate for entering water temperatures below 10°C is 2.2 l/m per kW.

Condensate Drain overfl ow.

- In areas where airborne bacteria may produce a “slimy” substance in the drain pan, it may be necessary to treat the drain pan chemically with an algaecide approximately every three months to minimize the problem. The condensate pan may also need to be cleaned periodically to insure indoor air quality. The condensate drain can pick up lint and dirt, especially with dirty fi lters. Inspect the drain twice a year to avoid the possibility of plugging and eventual

Compressor - Conduct annual amperage checks to insure that amp draw is no more than 10% greater than indicated on the serial plate data.

Water Coil Maintenance -

(All other water loop applications)

Generally water coil maintenance is not needed for closed loop systems. However, if the piping is known to have high dirt or debris content, it is best to establish a periodic maintenance schedule with the owner so the water coil can be checked regularly. Dirty installations are typically the result of deterioration of iron or galvanized piping or components in the system. Open cooling towers requiring heavy chemical treatment and mineral buildup through water use can also contribute to higher maintenance. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with both the heat exchanger material and copper water lines. Generally, the more water fl owing through the unit, the less chance for scaling. However, fl ow rates over 3.9 l/m per kW can produce water (or debris) velocities that can erode the heat exchanger wall and ultimately produce leaks.

Fan Motors - All units have lubricated fan motors. Fan motors should never be lubricated unless obvious, dry operation is suspected. Periodic maintenance oiling is not recommended, as it will result in dirt accumulating in the excess oil and cause eventual motor failure.

Conduct annual dry operation check and amperage check to insure amp draw is no more than 10% greater than indicated on serial plate data.

Belt - Check that the belt is tight. Retighten if needed.

Replace if it is split or cracked.

Air Coil sharp.

- The air coil must be cleaned to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or vacuum clean. Care must be taken not to damage the aluminum fi ns while cleaning. CAUTION: Fin edges are

Filters - Filters must be clean to obtain maximum performance. Filters should be inspected every month under normal operating conditions and be replaced when necessary. Units should never be operated without a fi lter.

Washable, high effi ciency, electrostatic fi lters, when dirty, can exhibit a very high pressure drop for the fan motor and reduce air fl ow, resulting in poor performance. It is especially important to provide consistent washing of these fi lters (in the opposite direction of the normal air fl ow) once per month using a high pressure wash similar to those found at self-serve car washes.

Refrigerant System - To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Reference the operating charts for pressures and temperatures. Verify that air and water fl ow rates are at proper levels before servicing the refrigerant circuit.
