THE SMART SOLUTION FOR ENERGY EFFICIENCY
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.
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. Remove any blower support packaging (water-to-air units only).
6. Loosen compressor bolts on units equipped with compressor spring vibration isolation until the compressor rides freely on the springs. Remove shipping restraints. (No action is required for compressors with rubber grommets.)
7. Some airfl ow patterns are fi eld convertible (horizontal units only). Locate the airfl ow conversion section of this IOM.
8. Locate and verify any hot water generator (HWG), hanger, or other accessory kit located in the compressor section or blower section.

General Information
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.
NOTICE! Failure to remove shipping brackets from spring-mounted compressors will cause excessive noise, and could cause component failure due to added vibration.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
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).
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.

Horizontal Installation
Mounting Horizontal Units
Horizontal units have hanger kits pre-installed from the factory as shown in Figure 1. Figure 3 shows a typical horizontal unit installation.
Horizontal heat pumps are typically suspended above a ceiling or within a soffi t using fi eld supplied, threaded rods sized to support the weight of the unit.
Use four (4) fi eld supplied threaded rods and factory provided vibration isolators to suspend the unit. Hang the unit clear of the fl oor slab above and support the unit by the mounting bracket assemblies only. DO NOT attach the unit fl ush with the fl oor slab above.
Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units (less than 2.5 tons/8.8kW) 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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
Overview - Horizontal units can be fi eld converted between side (straight) and back (end) discharge using the instructions below.
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 - It is best to fi eld convert the unit on the
ground before hanging. If the unit is already hung it should be taken down for the fi eld conversion.
Side to Back Discharge Conversion
1. Place unit in well lit area. Remove the screws as shown in Figure 4 to free top panel and discharge panel.
2. Lift out the access panel and set aside. Lift and rotate the discharge panel to the other position as shown, being careful with the blower wiring.
3. Check blower wire routing and connections for tension or contact with sheet metal edges. Re-route if necessary.
4. Check refrigerant tubing for contact with other components.
5. Reinstall top panel and screws noting that the location for some screws will have changed.
6. Manually spin the fan wheel to ensure that the wheel is not rubbing or obstructed.
7. Replace access 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.

Duct System Installatio
Horizontal Installation
Condensate Piping - Horizontal Units - A condensate
drain line must be installed and pitched away for the unit to allow for proper drainage. This connection must meet all local plumbing/building codes.
Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units (less than 2.5 tons/8.8 kW), ensure 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. Design the depth of the trap (water-seal) based upon the amount of ESP capability of the blower (where 2 inches [51mm] of ESP capability requires 2 inches [51mm] of trap depth). As a general rule, 1-1/2 inch [38mm] trap depth is the minimum.
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.

* Some units include a painted drain connection. Using a threaded pipe or similar device to clear any excess paint accumulated inside this fitting may ease final drain line installation.
CAUTION!
CAUTION! Ensure condensate line is pitched toward drain
1/8 inch per ft [11mm per m] of run.
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 THE CONDENSATE FLOW.
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.
10
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.

1. Install the unit on a piece of rubber, neoprene or other mounting pad material for sound isolation. The pad should be at least 3/8” [10mm] to 1/2” [13mm] in thickness. Extend the pad beyond all four edges of the unit.
2. Provide adequate clearance for fi lter replacement and drain pan cleaning. Do not block fi lter access with piping, conduit or other materials. Refer to unit submittal data or engineering design guide for dimensional data.
3. Provide access for fan and fan motor maintenance and for servicing the compressor and coils without removing the unit.
4. Provide an unobstructed path to the unit within the closet or mechanical room. Space should be suffi cient to allow removal of the unit, if necessary.
5. Provide access to water valves and fi ttings and screwdriver access to the unit side panels, discharge collar and all electrical connections.

Sound Attenuation for Vertical Units - Sound
attenuation is achieved by enclosing the unit within a small mechanical room or a closet. Additional measures for sound control include the following:
1. Mount the unit so that the return air inlet is 90° to the return air grille. Refer to Figure 9. Install a sound baffl e as illustrated to reduce line-of sight sound transmitted through return air grilles.
2. Mount the unit on a rubber or neoprene isolation pad to minimize vibration transmission to the building structure.
Figure 9: Vertical Sound Attenuation
Condensate Piping for Vertical Units - A condensate
line must be installed and pitched away from the unit to allow for proper drainage. This connection must meet all local plumbing/building codes. Vertical units utilize a condensate hose inside the cabinet as a trapping loop; therefore an external trap is not necessary. Figure 10a shows typical condensate connections. Figure 10b illustrates the internal trap for a typical vertical heat pump. Each unit must be installed with its own individual vent (where necessary) and a means to fl ush or blow out the condensate drain line. Do not install units with a common trap and/or vent.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
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.

Piping Installation
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.
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).
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.
Note: When antifreeze is used in the loop, ensure that it is compatible with the Tefl on
®
tape or pipe joint
compound that is applied.
Maximum allowable torque for brass fi ttings is 30 ft-lbs [41 N-m]. If a torque wrench is not available, tighten fi nger-tight plus one quarter turn. Tighten steel fi ttings as necessary.
Optional pressure-rated hose assemblies designed specifi cally for use with ClimateMaster units are available. Similar hoses can be obtained from alternate suppliers. Supply and return hoses are fi tted with swivel-joint fi ttings at one end to prevent kinking during installation.
CAUTION!
CAUTION! Piping must comply with all applicable codes.

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. Consideration should be given to insulating the piping surfaces to avoid condensation. ClimateMaster recommends unit insulation any time the water temperature is expected to be below 60ºF (15.6ºC). Metal to plastic threaded joints should never be used due to their tendency to leak over time.

Tefl o n 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 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.
tape thread sealant is recommended to
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 2.25 and 3.5 gpm per ton [2.9 and 4.5 l/m per kW] of cooling capacity. ClimateMaster recommends 3 gpm per ton [3.9 l/m per kW] for most applications of water loop heat pumps. To ensure proper maintenance and servicing, P/T ports are imperative for temperature and fl ow verifi cation, as well as performance checks.
Water loop heat pump (cooling tower/boiler) systems typically utilize a common loop, maintained between 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 fi ltering will be necessary.

CAUTION!
CAUTION! The following instructions represent industry accepted installation practices for closed loop earth coupled heat pump systems. Instructions are provided to assist the contractor in installing trouble free ground loops. These instructions are recommendations only. 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.
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 13. 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 with units that do not include vFlow so that fl ow can be measured using the pressure drop of the unit heat exchanger. Units equipped with any of the four vFlow confi gurations have built in Schrader ports. Water temperature may be viewed on the iGate communicating thermostat.
Earth loop temperatures can range between 25 and 110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm [2.41 to
3.23 l/m per kW] of cooling capacity is recommended in
these applications.

Ground-Loop Heat Pump Applications
Test individual horizontal loop circuits before backfi lling. Test vertical U-bends and pond loop assemblies prior to installation. Pressures of at least 100 psi [689 kPa] should be used when testing. Do not exceed the pipe pressure rating. Test entire system when all loops are assembled.
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
I
n areas where minimum entering loop temperatures drop below 40°F [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 offi ce should be consulted to determine the antifreeze best suited to your area. Freeze 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 22 to 25°F [-6 to -4°C] and freeze protection should be at 15°F [-10°C]. Calculation is as follows: 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 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.

loop piping is shown in accompanying illustration. 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 flow can be measured using the pressure drop of the unit heat exchanger. Water temperature may be viewed on the iGate communicating thermostat. Supply and return water piping materials should be limited to copper, HPDE, or other acceptable high temperature material. Note that PVC or CPVC material is not recommended as they are not compatible with the polyolester oil used in HFC-410A products.

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 Quality Standards
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, 150°F [66°C] for direct use (well water/open loop); 90°F [32°F] for indirect use. A monitoring 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 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.

- Use a closed, bladder-type
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 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, 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 Control Valve
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. Ensure 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. Note the special wiring diagrams for slow closing valves (shown later in this manual).
