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: Notification of installation, operation, or maintenance information, which is important, but which is not hazard-related.
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 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. No tify your equipment supplier of all damage within fifteen
(15) days of shipment.
⚠ 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 proficiency 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 filters can quickly become clogged with construction dirt and debris, which may cause system damage and void product warranty.
⚠ WARNING!
⚠
WARNING! The installation of water-source heat pumps 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.
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 cosHKVy equipment clean- up.
Examine all pipes, fittings, and valves before installing any of the system components. Remove any dirt or debris found in or on these components.

Installation, Operation & Maintenance - HKV Compact Series
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 configurations are typ ically 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.
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 finished.
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 airflow patterns and some control box locations are field convertible. Locate the conversion section of this IOM.
General Information, Cont’d.
⚠ 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 will 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.

HKV units are typically installed in a floor level closet or in a small mechanical room. Refer to Figure 2b 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 HKV units. Failure to follow these guidelines could result in unsatisfactory unit performance and/ or premature failure of some unit components. Heat
Controller 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 fullsized 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.

Installation, Operation & Maintenance - HKV Series
• 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 HKV 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. Mixed air entering unit must be less than 95/75F in cooling mode and greater than
60F in heating mode.

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 flushing.
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 flow rate. Install an angle adapter to avoid sharp bends in the hose when the radius falls below the required minimum.

Figure 3 illustrates a typical trap and vent used with HKV series equipment.
Each unit must be installed with its own individual line to the building main condensate drain line or riser. Provide a means to flush 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

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 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 Heat
Controller in different configurations as shown in Figure
4 for connection between the HKV Series and the piping system. The hose kits include shut off valves, P/T plugs for performance measurement, high pressure stainless steel braid hose, "Y" type strainer with blowdown valve, and
"J" type swivel connection. Balancing valves to facilitate the balancing of the system, 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 flushed to remove dirt, piping chips, and other foreign material prior to operation. See Piping
System Cleaning and Flushing Procedures.
The flow rate is usually set between 2.25 and 3.5 gpm per ton [2.9 l/m and 4.5 l/m per kW] of cooling capacity.
Heat Controller 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.
Low Water Temperature Cutout Setting -
CXM2 or DXM2.5 Control: When an antifreeze is selected, the LT1 jumper (JW3) should be clipped to select the low temperature (Antifreeze 13°F [-10.6°C]) setpoint to avoid nuisance faults. See Low Water Temperature Cutout

Ground-Loop Heat Pump Applications
⚠ CAUTION!
⚠
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 recommended 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.
Piping Installation - The typical closed loop ground source system is shown in Figure 5. 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 (2.41 l/m to 3.23 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.
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.

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 2 for the amount of antifreeze.
Antifreeze concentration should be checked from a well mixed sample using a hydrometer to measure specific gravity.
Low Water Temperature Cut-Out Setting -
CXM2 or DXM2.5 Control: When an antifreeze is selected, the LT1 jumper (JW3) should be clipped to select the low temperature (Antifreeze 10°F [-12.2°C]) setpoint to avoid nuisance faults.
Ground-Water Heat Pump Applications
Shut off valves should be included in case of servicing. Boiler drains or other valves should be ‘tee’d’ into the line to allow acid 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 oils used in HFC-410A products and piping system failure and property damage may result.
⚠ WARNING!
⚠
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.
Water quantity should be plentiful and of good quality.
Consult Table 3 for water quality requirements. The unit can be ordered with either a copper or cupro-nickel 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, a closed loop system is recommended. Heat exchanger coils 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. 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 flushing.
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 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, the slow closing valve can draw up to 35VA. This can overload smaller
40 or 50 VA transformers depending on the other controls employed. A typical pilot operated solenoid valve draws approximately 15VA.
Flow Regulation - Flow regulation can be accomplished by two methods. 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 7. 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
(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 are 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.

Water Quality Requirements, Cont’d.
1. The Heat Controller Water Quality Table provides water quality requirements for coaxial & brazed plate heat exchangers.
2. The water must be evaluated by an independent testing facility comparing site samples against this table. When water properties are outside of these parameters, the water must either be treated by a professional water treatment specialist to bring the water quality within the boundaries of this specification, or an external secondary heat exchanger must be used to isolate the heat pump water system from the unsuitable water. Failure to do so will void the warranty of the heat pump system and will limit liability for damage caused by leaks or system failure.
3. Regular sampling, testing and treatment of the water is necessary to assure that the water quality remains within acceptable levels thereby allowing the heat pump to operate at optimum levels.
4. If closed‐loop systems are turned off for extended periods, water samples must be tested prior to operating the system.
5. For optimal performance, it is recommended that the closed‐loop piping systems are initially filled with de‐ ionized water.
6. Well water with chemistry outside of these boundaries, and salt water or brackish water requires an external secondary heat exchanger. Surface/Pond water should not be used.
7. If water temperature is expected to fall below 40°F, antifreeze is required. Refer to the heat pump IOM for the correct solution ratios to prevent freezing.
α Hydrogen Sulfide has an odor of rotten eggs. If one detects this smell, a test for H2S must be performed.
If H2S is detected above the limit indicated, remediation is necessary (Consult with your Water
Testing/Treatment Professional) or a secondary heat exchanger is required using appropriate materials as recommended by the heat exchanger supplier.
β Suspended solids and particulates must be filtered to prevent fouling and failure of heat exchangers.
Strainers or particulate filters must be installed to provide a maximum particle size of 600 micron (0.60 mm, 0.023 in.) using a 20 to 30 mesh screen size.
When a loop is installed in areas with fine material such as sand or clay, further filtration is required to a maximum of 100 micron. Refer to the Strainer / Filter
Sizing Chart to capture the particle sizes encountered on the site.
χ An electrical grounding system using a dedicated ground rod meeting NEC and Local Electrical codes must be installed. Building Ground must not be connected the WSHP piping system or other plumbing pipes.
δ Refer to IOM for instructions on measuring resistance and leakage currents within water loops.
Do not use PVC pipe for water loop (compressor POE oil and glycols damage PVC) use of HDPE pipe is recommended.

Installation, Operation & Maintenance - HKV Series
Electrical – Power Wiring
⚠ WARNING!
⚠
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.
⚠ CAUTION!
⚠
CAUTION! Use only copper conductors for field installed electrical wiring. Unit terminals are not designed to accept other types of conductors.
⚠ WARNING!
⚠
WARNING! Disconnect electrical power source to prevent injury or death from electrical shock.
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.
HKV Power Connection - Line voltage connection is made by connecting the incoming line voltage wires to the power block as shown in Figure 6. Consult Table 4a and
4b for correct fuse size.
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 backplate against the wall so that it appears level and so the thermostat wires protrude through the middle of the backplate. Mark the position of the backplate mounting holes and drill holes with a 3/16" 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 13 to the low voltage terminal strip in the CXM2/DXM2.5
Control as shown in Figure 7 using 18 AWG thermostat wire of minimum length.
Figure 8: Typical HKV Series Line Voltage Field Wiring
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 (208V) and the Orange (230V) at the contactor terminal L2.
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.
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.

Low Water Temperature Cutout - LT1 - The CXM2/
DXM2.5 control allows the field selection of source fluid low temperature cutout points. The factory setting ofLT1 is set for water (30°F [-1.1°C]). In cold temperature applications jumper JW3 (LT1- antifreeze 10°F [-12.2°C]) should be clipped as shown in Figure 10 to change the setting to 10°F [-12.2°C], a more suitable temperature when using antifreezes. It should be noted that the extended range option should be specified to operate the
HKV Series at entering water temperatures below 60°F
[15°C].
Accessory Connections - A terminal paralleling the compressor contactor coil has been provided on the
CXM2/DXM2.5 control of the HKV line. "A" has been provided to control accessory devices, such as water valves, electronic air cleaners, humidifiers, etc. Note:
This terminal should be used only with 24 Volt signals and not line voltage signals. This signal operates with the compressor contactor. See Figure 11 or the wiring
Figure 11: Accessory Wiring
Electrical - Low Voltage
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 can overheat the anticipators of electromechanical thermostats. Therefore only relay or triac based thermostats should be used.

Water Solenoid Valves - When using external solenoid valves on ground water installations, a slow closing valve may be desired. Figure 11 illustrates a typical slow closing water control valve wiring which will limit wasted water during a lockout condition. A slow closing valve may be required to prevent water hammer. When using an AVM -Taco Slow Closing valve on HKV Series equipment Figure 12 wiring should be utilized. The valve takes approximately 60 seconds to open (very little HKV water will flow before 45 seconds) and it activates the compressor only after the valve is completely opened (by closing its end switch). Only relay or triac based electronic thermostats should be used with the AVM valve. When wired as shown, the valve will operate properly with the following notations:

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.
Airflow and External Static Pressure
Selection Adjustment
The HKV 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 may require the optional large fan motor. Please specify static range and motor horsepower when ordering. See model nomenclature.
Sheave Adjustment
The HKV Series is supplied with variable sheave drive on the fan motor to adjust for differing airflows at various
ESP conditions. Select an airflow 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.
Belt Tensioning
An overly loose belt will, upon motor start, produce a slippage 'squeel' and cause premature belt failure and or intermittent airflow. An overly tight belt can cause premature motor or blower bearing failure.
Sheave and Pulley Alignment
Verify belt is straight; misalignment will cause premature belt failure. Adjust sheave if needed.
Belt Tensioning Procedure - HKV
Blower motors for HKV models are slide base mounted.
To adjust the belt tension:
1. Loosen the four (4) bolts that lock the base to the slide rails.
2. Insert a socket into the opening at the front of the base assembly.
3. Turn counter clock wise to tighten or clock wise to loosen the belt.
4. The belt should be tensioned using a tension gauge method such as the Browning Belt Tensioner to set proper belt tension (see next page).
5. After belt tension is set secure the (4) locking bolts.
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.

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 will damage the belt and cause early failure.

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.
NOTE: The ratio of deflection to belt span is 1:64.

Unit Commissioning & Operating Conditions
Environment This unit is designed for indoor installation only. 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 return air temperature, airflow, water temperature, water flow rate and ambient air temperature. This water to air 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 air and 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.
The operating table indicates the maximum and minimum ranges of the unit.
For more specific unit performance reference the product catalog, the submittal data sheets or contact your supplier for assistance.

Piping System Cleaning & Flushing
⚠ CAUTION!
⚠
CAUTION! To avoid possible damage to a plastic (PVC) piping system, do not allow temperatures to exceed 110°F
[43°C].
⚠ 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.
Note: Heat Controller strongly recommends all piping connections, both internal and external to the unit, be pressure tested for leakage by an appropriate method prior to any finishing of the interior space or before access to all connections is limited. Heat Controller will not be responsible or liable for damages from water leaks due to inadequate or a lack of pressurized leak testing during installation.
Cleaning and flushing of the WLHP piping system is the single most important step to ensure proper start-up and continued efficient operation of the system.
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. (Heat Controller recommends a strainer with a #20 stainless steel wire mesh.) 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. Set the boiler to raise the loop temperature to approximately 85°F [29°C]. 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 trisodium phosphate in a proportion of approximately one pound per 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 about 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. Refill the system and bleed off all air.
9. Test the system pH with litmus paper. The system water should be slightly alkaline (pH 7.5-8.5). Add chemicals, as appropriate, to maintain acidity levels.
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.

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.
BEFORE POWERING SYSTEM, please check the following:
UNIT CHECKOUT
Line Voltage and Wiring: Ensure Voltage is within an acceptable range for the unit and wiring and fuses/ breakers are properly sized. Low voltage wiring is complete.
Unit Control Transformer: Ensure transformer has properly selected control voltage tap. 208-230V units are factory wired for 208V operation unless specified otherwise.
Balancing/Shutoff Valves: Ensure all isolation valves are open (after system flushing - see System
Checkout) water control valves wired and open or coax may freeze and burst.
Entering Water and Air: Ensure entering water and air temperatures are within operating limits of Table 11b.
Low Water Temperature Cutout: Verify low water temperature cut-out on CXM2/DXM2.5 is properly set.
Unit Blower Wheel: Manually rotate blower wheel to verify free rotation and ensure that all blower wheels are secured to blower shaft and centered in housing.
Blower Motor: Verify motor bolts are tight. DO NOT oil motors upon start-up. Fan motors are pre-oiled at 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: Condensate line is open, trapped, vented, and properly pitched toward drain.
Water Flow Balancing: Verify inlet and outlet water temperatures are recorded for each heat pump upon startup. This check can eliminate nuisance trip outs and high velocity water flows that can erode heat exchangers.
Unit Air Coil & Filters: Ensure filter is clean and accessible. To obtain maximum performance and avoid possible condensate blow-off the coil should be cleaned using a 10% solution of dish washing detergent.
Unit Controls: Verify CXM2 or DXM2.5 field selection options are proper and complete.
SYSTEM CHECKOUT
System Water Temperature: Check water temperature for proper range and also verify heating and cooling setpoints for proper operation.
System pH: System water pH is 7.5 - 8.5. Proper pH promotes longevity of hoses and fittings.
System Flushing: Verify all hoses are connected end to end when flushing to ensure debris bypasses unit heat exchanger and water valves etc. Water used in the system must be potable quality initially and clean of dirt, piping slag, and strong chemical cleaning agents.
Verify 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 the standby pump is properly installed and in operating condition.
System Controls: Verify system controls function and operate in the proper sequence.
Low Water Temperature Cutout: Verify low water temperature cut-out controls are provided for the outdoor portion of the loop or operating problems will occur.
System Control Center: Verify control center and alarm panel for proper setpoints and operation (if used).
Miscellaneous: Note any questionable aspects of the installation.
Log Data: Record data on startup log sheet in this manual or on web site. keep log for future reference.
⚠ WARNING!
⚠
WARNING! Verify ALL water controls are open and allow water flow prior to engaging the compressor. Freezing of the coax or water lines can permanently damage the heat pump.
⚠ WARNING!
⚠
WARNING! To avoid equipment damage, DO NOT leave system filled in a building without heat during the winter unless antifreeze is added to system water. Condenser coils never fully drain by themselves and will freeze unless winterized with antifreeze.

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.
⚠ CAUTION!
⚠
INSTALLER CAUTION! After making water connections on units equipped with ClimaDry ® , ensure the three union nuts on the internal three-way water valve are tight.
1. Turn thermostat fan position to “ON”. Blower should start.
2. Balance air flow at registers.
3. Adjust all valves to their full open position. Turn on the line power to all heat pump units.
4. Operate unit in cooling cycle. Room temperature should be approximately 45-100°F [7-38°C] DB.
For Start-up check, loop water temperature entering the heat pumps should be between 45°F [7°C] and 110°F
[43°C].
5. Two factors determine the operating limits of a Heat
Controller HKV System– (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 levels to ensure proper unit operation.
a. Adjust the unit thermostat to the warmest 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 five minute time delay in the control circuit that can be eliminated on the
CXM2 PCB as shown below in Figure 14. See controls description for detailed features of the control.
c. Verify that the compressor is on and that the water flow rate is correct by measuring pressure drop through the heat exchanger using the Pete’s plugs and comparing to Table 12.
d. Check the elevation and cleanliness of the condensate lines. Dripping may be a sign of a blocked line. Check that the condensate trap includes a water seal.
e. Refer to Table 14. Check the temperature of both supply and discharge water. If temperature is within range, proceed with test. If temperature is outside operating range, check cooling refrigerant pressures in Table 13. Verify correct water flow by comparing
W unit pressure drop across the heat exchanger versus the data in Table 14. Heat of rejection can be
C
R
46
AL1 f. Check air temperature drop across the coil when compressor is operating. Air temperature should drop between 15°F [8°C] and 25°F [14°C].
g. Turn thermostat to “OFF” position. A hissing noise indicates proper functioning of the reversing valve.
6. Operate the heat pump in the heating cycle immediately after checking cooling cycle operation. Allow five (5) minutes between tests for pressure to equalize or cycle the reversing valve to equalize.
a. Turn thermostat to lowest setting and set thermostat switch to “HEAT” position.
b. Slowly turn thermostat to a higher temperature until the compressor activates.
c. Check for warm air delivery at the unit grille within a few minutes after the unit has begun to operate.
d. Check the temperature of both supply and discharge water. Refer to Table 13. If temperature is within range, proceed with test. If temperature is outside operating range, check heating refrigerant pressures in Table 13.
e. Check air temperature rise across the coil when compressor is operating. Air temperature should rise between 20°F [11°C] and 30°F [17°C]. Heat of extraction can be calculated and compared to specification catalog.
f. Check for vibration, noise, and water leaks.
7. If unit fails to operate, perform troubleshooting analysis
(CXM2 AOM or DXM2.5 AOM). If the check described fails to reveal the problem and the unit still does not operate, contact a trained service technician to ensure 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 Heat Controller.
Note: If performance during any mode appears abnormal, refer to the troubleshooting section of CXM2 or DXM2.5
AOM. To obtain maximum performance the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended.

CXM2/DXM2.5 Safety Control Reset - Lockout - In
Lockout mode, the Status LED will begin fast flashing. The compressor relay is turned off immediately. Lockout mode can be soft reset via the thermostat “Y” input or can be hard reset via the disconnect. The last fault causing the lockout will be stored in memory and can be viewed by going into test mode.
Fault Retry - In Fault Retry mode, the Status LED begins slow flashing to signal that the control is trying to recover from a fault input. The CXM2 control will stage off the outputs and then “try again” to satisfy the thermostat "Y" input call. Once the thermostat input calls are satisfied, the control will continue on as if no fault occurred. If 3 consecutive faults occur without satisfying the thermostat
"Y" input call, then the control will go to Lockout mode.
The last fault causing the lockout will be stored in memory and can be viewed by going into test mode.
Consult the CXM2 AOM or DXM2.5 AOM for complete descriptions.
⚠ CAUTION!
⚠
CAUTION! Do not restart units without inspection and remedy of faulting condition. Equipment damage may occur.

Installation, Operation & Maintenance - HKV Series
Preventive Maintenance
Water Coil Maintenance
(Direct Ground Water Applications Only)
If the installation is performed in an area with a known high mineral content (125 P.P.M. or greater) in the water, it is best to establish with the owner a periodic maintenance schedule 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 either the heat exchanger material or copper water lines. Generally, the more water flowing through the unit the less chance for scaling therefore 1.5 gpm per ton [2.0 l/m per kW] is recommended as a minimum flow.
Filters
Filters must be clean to obtain maximum performance.
They should be inspected every month under normal operating conditions and be replaced when necessary.
Units should never be operated without a filter.
Washable high efficiency electrostatic filters, when dirty, can exhibit a very high pressure drop for the fan motor and reduce air flow resulting in poor performance. It is especially important to provide consistent washing of these filters (in opposite direction of the normal air flow) once per month using a high pressure wash similar to that found at self-serve car washes.
Condensate Drain
In areas where airborne bacteria produce a slime in the drain pan, it may be necessary to treat chemically with an algaecide every three months or so to minimize the problem. The condensate pan may also need to be cleaned periodically to assure indoor air quality. The condensate drain can pick up lint and dirt, especially with dirty filters. Inspect the drain twice a year to avoid the possibility of overflow.
Compressor
Conduct annual amperage checks to ensure amp draw is no more than 10% greater than that indicated by serial plate data.
Water Coil Maintenance
(All Other Water Loop Applications)
Generally water coil maintenance is not needed however, if the installation is located in a system with a known high dirt or debris content, it is best to establish with the owner a periodic maintenance schedule so the coil can be checked regularly. These dirty installations are a result of the deterioration of iron or galvanized piping or components in the system or open cooling towers requiring heavy chemical treatment and mineral buildup through water use. 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 flowing through the unit, the less chance for scaling, however flow rates over 3 gpm per ton 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. Inspection should be performed for proper tension and excessive wear of drive belts every three months.
Air Coil
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 fins while cleaning.
CAUTION: Fin edges are sharp.
Cabinet
Do not allow water to stay in contact with the cabinet for long periods of time to prevent corrosion of the cabinet sheet metal. Generally vertical cabinets are set up from the floor a few inches for prevention. The cabinet can be cleaned using a mild detergent.
Refrigerant System
To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal.
Reference the operating chart for pressure and temperatures. Verify that air and water flow rates and temperatures are at proper levels before servicing the refrigerant circuit.
⚠ 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.
