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

 WARNING! 

WARNING! Verify refrigerant type before proceeding. Units

are shipped with R-22, R-407c and R-410A (EarthPure®) refrigerants. The unit label will indicate which refrigerant is provided. The EarthPure® Application and Service Manual should be read and understood before attempting to service refrigerant circuits with R-407c or R-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: 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 hazardrelated.

 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.

General Information

Inspection

Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the 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. Stack units a maximum of 3 units high.

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 cleanup.

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.

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.

6. Loosen compressor bolts on units equipped with compressor spring vibration isolation until the compressor rides freely on the springs. Remove shipping restraints.

7. REMOVE COMPRESSOR SUPPORT PLATE 1/4” SHIPPING BOLTS (2 on each side) TO MAXIMIZE VIBRATION AND SOUND ATTENUATION.

 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 springmounted compressors will cause excessive noise, and could cause component failure due to added vibration.

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.

Installation

The installation of Console Water-Source Heat Pumps and all associated components, parts and accessories that 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.

NOTE: An Installation Checklist is provided in this

manual. Complete this checklist after all installation procedures are completed. A periodic maintenance checklist provided in the Maintenance section outlines recommended maintenance schedules. A Start-Up Inspection Log is also included at the end of this manual to encourage thorough unit checkout at initial start-up. These checklists are not a substitute for the detailed information found in the Installation section of this manual

1. Console units are typically installed along an outside

2. Unpack the Console Unit from the shipping carton.

3. Remove compressor isolation plate shipping screws

4. Using a carpenter's square and a level, ensure the

wall of the room. Provide adequate space in front of the unit for service and maintenance. Locate the Console Unit so that it provides adequate air circulation throughout the room.

Remove the front cabinet by lifting up and away from the backplate. Protect the cabinet from damage during installation by returning it to its original packaging until required.

(4) as shown in Figure 1a. (All CCE and TRC09-12)

Screws

5. Select the proper fasteners to connect the backplate securely to the wall.

6. Fasten the backplate onto the wall through the screw holes located in the back ﬂ ange. Secure the subbase in place.

7. Make all necessary electrical connections as described in the Electrical Wiring section of this manual. Consult the wiring diagram to ensure proper hook-up.

8. Connect the ﬁ nal piping as described in the Supply and Return Piping and Condensate Piping section of the manual. Install shut-off valves, piping and/or hoses and other accessories as speciﬁ ed.

9. Before making the ﬁ nal water connections, ﬂ ush the system as described in the Start Up section of this manual. After ﬂ ushing the system, connect piping and hoses to the proper supply, return and condensate connections of the unit.

NOTE: When necessary, use adapters to connect hoses.

10. Install any other system components as required following manufacturer's instructions.

11. After Start-up, reinstall the front cabinet by carefully lowering the front cabinet over the chassis onto the backplate.

Supply and Return Hoses

Optional pressure-rated hose assemblies are available for use with ClimateMaster Console Units. Use the following guidelines when installing supply and return hose assemblies.

1. Install supply and return hoses ﬁ tted with swivel-joint ﬁ ttings at one end to prevent the hose from twisting.

2. Use adapters to secure the hose assembly to the unit and the riser.

3. Do not allow the hose to twist during installation. Twisting may damage the hose wall or the interior rubber compound.

4. Use pipe joint compound sparingly on the pipe threads of the ﬁ tting adapters.

5. Prevent sealant from reaching the ﬂ ared surfaces of the joint.

6. Do not use pipe joint compound when teﬂ on thread tape is pre-applied to hose assemblies or when ﬂ ared-end connections are used.

7. Maximum torque which may be applied to brass ﬁ ttings is 30 ft-lbs [41 N-m]. When a torque wrench is not used, tighten brass ﬁ ttings ﬁ nger-tight plus one quarter turn.

8. Tighten steel ﬁ ttings as necessary.

9. Shut-off/balancing valves, ﬂ ow indicators, and drain tees in the supply runout and return at each ﬂ oor to aid in loop balancing and servicing.

Installation

 CAUTION! 

Loop Fluids should be of good quality with no more than 0.50 ppm of chlorides w/copper heat exchangers (125 ppm w/ Cupro-nickel) to prevent corrosion and should also be ﬁ ltered to a maximum 800 micron [0.8mm particle size to prevent erosion of the heat exchangers.

Condensate Piping

Unit is supplied with condensate drain hose, 5/8 inch [16mm] I.D. ﬂ exible plastic nonpressure-rated, protruding from piping side of unit. Connect this hose to building drain. Avoid making kinks in hose to ensure an unobstructed ﬂ ow of condensate from the unit to the

drain. DO NOT twist, pull hose out, or push excess hose into unit. If hose will not connect to your building

drain several options include, relocate end of building drain, add to or cut hose, use hard plastic or copper elbow ﬁ ttings for tight radii (put inside hose). Keep hose positioned within or over subbase area so hose does not interfere with front cabinet. Cabinet should not push or reroute hose. Clamp all joints watertight. Check for leaks.

Internally the drain hose is clamped to drain pan and pitched correctly. Horizontal runs of condensate hose should be pitched downward 1/4 inch minimum for every foot [10mm per 46cm] of hose. Avoid low points because dirt collects in these areas and may cause blockage. If blocked the condensate level in drain pan increases. When the level gets too high, the Console unit has sensor switch that will shut unit off. Overﬂ ow may still occur. If the building drain connection is parallel with ﬂ oor, the height can be up to 1-1/2 inches [38mm] above the subbase for proper pitch and correct drainage. Up to 5 inches [127mm] above the subbase is allowable, but drainage will be slower. When the drain connection is 2-1/2 to 5 inches [64 to 127mm] above, the hose inside the unit will act as a trap. Heights of more than 5 inches [127mm] above the subbase are NOT allowable (condensate overﬂ ow may occur). If the unit has a disconnect option, drain locations are limited. See unit conﬁ guration pages for details.

Field installation of a trap or vent is not required unless speciﬁ ed by local codes. Console units are designed in a blow-through conﬁ guration. The condensate drain pan is located on the outlet side of the blower so that the pressure in the drain pan is higher than atmospheric pressures.

When drain connection is completed check for proper drainage and leaks. Correct if necessary.

If trap is used, check and clean often. See Preventive Maintenance Instructions.

Piping Connections

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.

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 anti-freeze is used in the loop, insure 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.

Table 1: Metal Hose Minimum Bend Radii

Hose Diameter Minimum Bend Radii

1/2" [12.7mm] 2-1/2" [6.4cm] 3/4" [19.1mm] 4" [10.2cm]

1-1/4" [31.8mm] 6-3/4" [17.1cm]

 CAUTION! 

CAUTION! Do not bend or kink supply lines or hoses.

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.

 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 300 psig and a cut-in pressure of 250 psig. This pressure switch can be ordered from ClimateMaster with a 1/4” internal ﬂ are connection as part number 39B0005N02.

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 50°F [10°C], 1/2” (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.

Te ﬂ 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 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. 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 2.25 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 insure 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.

Low Water Temperature Cutout Setting CXM or DXM Control

When antifreeze is selected, the FP1 jumper (JW3) should be clipped to select the low temperature (antifreeze 13°F [-10.6°C]) set point and avoid nuisance faults (see “Low Water Temperature Cutout Selection” in this manual). NOTE: Low water temperature operation requires extended range

Ground-Loop Heat Pump Applications

 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

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.

Earth loop temperatures can range between 25 and 110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm per ton [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 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

In 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 manager should be consulted for 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 25 to 22°F [-4 to -6°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.

Ground-Water Heat Pump Applications

Open Loop - Ground Water Systems

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. Piping materials should be limited to copper or PVC SCH80.

Note: Due to the pressure and temperature extremes, PVC SCH40 is not recommended.

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 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, 150°F [66°C] for direct use (well water/open loop) and DHW (desuperheater); 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

Use a closed, bladder-type 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 Control Valve

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..

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. Since the pressure is constantly varying, two pressure gauges may be needed. Adjust the valve until the desired ﬂ ow of 1.5 to 2 gpm per ton [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 50°F [10°C], 2 gpm per ton (2.6 l/m per kW) is required.

Water Coil Low Temperature Limit Setting

For all open loop systems the 30°F [-1.1°C] FP1 setting (factory setting-water) 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.

 CAUTION! 

CAUTION! Many units 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 235 psig and a cut-in pressure of 190 psig. This pressure switch can be ordered from ClimateMaster with a 1/4” internal ﬂ are connection as part number 39B0005N01.

NOTICE! Ground-water applications for commercial buildings with more than 2-3 units should include a plate frame heat-exchanger to isolate the heat pumps from the ground-water and conﬁ ne heat exchanger cleanings to one location and lessen maintenance. Direct use of ground-water may increase the frequency of heat pump maintenance and may shorten life expectancy.

electrical wiring. Unit terminals are not designed to accept other types of conductors.

Electrical - Line Voltage

All ﬁ eld installed wiring, including electrical ground, must comply with the National Electrical Code as well as all applicable local codes. Refer to the unit electrical data for fuse sizes. Consult wiring diagram for ﬁ eld connections that must be made by the installing (or electrical) contractor. All ﬁ nal electrical connections must be made with a length of ﬂ exible conduit to minimize vibration and sound transmission to the building.

Table 4: CCE Electrical Data

Use only copper conductors for ﬁ eld installed

General Line Voltage Wiring

Be sure the available power is the same voltage and phase 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.

Power Connection

Line voltage connection is made by connecting the incoming line voltage wires to the “L” side of the contactor. Consult Tables 4 through 5 for correct fuse size.

Transformer

All commercial dual voltage units are factory wired for 208/60/1 or 240/50/1. If supply voltage is 230/60/1 or 220/50/1, installer must rewire transformer. See wire diagram for connections.

Unit-Mounted Controls, TRC & CCE Units, Rev. B

CCE Revision B models and TRC models include digital display unit-mounted controls (see picture, below). Either manual changeover (MCO) or auto changeover (ACO) controls are available, as indicated by the model number. The room temperature will appear after the set point has been displayed for 3 seconds. To read “set point” press “SET”. To change heating or cooling setpoints, slide switch to desired mode (i.e. heating or cooling), and press the arrow up or arrow down key to change the set point. The differential between heating and cooling set points is factory set at 3°F (1.5°C).

Figure 5: Example MCO Thermostat

Unit-mounted controls are shipped from the factory for display in degrees Farhenheit. To change display to Celcius, follow the instructions below.

1. Turn power OFF.

2. Remove the thermostat cover (NOTE: Make sure to depress the tab at the top of the thermostat to avoid damaging the cover) F/C jumper is located at top left of display case (see Fig 6).

3. Remove the Jumper for °C selection; position jumper on both pins for °F selection.

4. Turn power ON.

5. Press RESET if desired measurement scale has not been changed (See Fig 6).

Electrical - Low Voltage

Optional Wall-Mounted Thermostat

CCE & TRC WSHP units are built with standard internal thermostats in either manual changeover (MCO) or automatic changeover (ACO) conﬁ guration. No external, ﬁ eld-installed low-voltage wiring is required.

When desired, the unit can be furnished with a 24-volt control circuit which is ﬁ eld-wired to a ClimateMaster- supplied accessory remote thermostat.

Zone integrity must be maintained to efﬁ ciently control units or groups of units. Unless zones of control are considered and accounted for, adjacent units may operate in heating and cooling modes simultaneously.

Low-voltage wiring between the unit and the wall thermostat must comply with all applicable electrical codes (i.e., NEC and local codes), and be completed before the unit is installed.

Thermostat Installation

The thermostat should be located on an interior wall in a larger room, away from supply air 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 7 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.

CXM Controls

CXM Control

For detailed control information, see CXM or DXM Application, Operation and Maintenance (AOM) manual (part # 97B0003N12 or part #97B0003N13).

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 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 Conﬁ guration Options

Note: In the following ﬁ eld conﬁ guration options, jumper wires should be clipped ONLY when power is removed from the CXM control.

On = Enabled. Off = Disabled.

DIP switch 2: Stage 2 Selection - provides selection of whether compressor has an “on” delay. If set to stage 2, the compressor will have a 3 second delay before energizing. Also, if set for stage 2, the alarm relay will NOT cycle during test mode.

On = Stage 1. Off = Stage 2

DIP switch 3: Not Used. DIP switch 4: DDC Output at EH2 - 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.

NOTE: Some CXM controls only have a 2 position DIP switch package. If this is the case, this option can be selected by clipping the jumper which is in position 4 of SW1.

Jumper not clipped = EH2 Normal. Jumper clipped = DDC Output at EH2.

DIP switch 5: Factory Setting - Normal position is “On.” Do not change selection unless instructed to do so by the factory.

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 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 set point. Note that the FP1 thermistor is sensing refrigerant temperature between the coaxial heat exchanger and the expansion device (TXV or cap tube). Therefore, the 50°F [10°C] setting is not 50°F [10°C] water, but approximately 60°F [16°C] EWT.

On = 50°F [10°C]. Off = 40°F [16°C].

Safety Features - CXM/DXM Controls

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. 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: While in lockout mode, if W becomes active (CXM), emergency heat mode will occur. If DXM is conﬁ gured for heat pump thermostat type (DIP 1.3), emergency heat will become active if O/ W2 is energized. 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. 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

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

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

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 125°F [52°C] for 30 continuous seconds, or:

b) In cooling mode with compressor energized, FP1 is

greater than 125°F [52°C] for 30 continuous seconds, or:

c) In cooling mode with compressor energized, FP2 is

less than 40°F [4.5°C] for 30 continuous seconds.

Safety Features - CXM/DXM Controls

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)

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.

CXM/DXM Controls

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.

Piping System Cleaning and Flushing

Cleaning and ﬂ ushing the WLHP piping system is the single most important step to insure proper start-up and continued efﬁ cient operation of the system. Follow the instructions below to properly clean and ﬂ ush the system:

Insure 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.

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 makeup 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 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 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.

 CAUTION! 

CAUTION! To avoid possible damage to a plastic (PVC)

piping system, do not allow temperatures to exceed 113°F [45°C].

NOTE: ClimateMaster 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. ClimateMaster 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.

Unit and System Checkout Procedure

Unit and System Checkout

BEFORE POWERING SYSTEM, please check the following:

UNIT CHECKOUT

 Balancing/shutoff valves: Insure that all isolation

valves are open and water control valves are wired.

 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: Insure that transformer

has the properly selected voltage tap. Commercial 208-230V units are factory wired for 208V operation unless speciﬁ ed otherwise.

 Entering water and air: Insure that entering water and

air temperatures are within operating limits of Table 8.

 Low water temperature cutout: Verify that low water

temperature cut-out on the CXM/DXM control is properly set.

 Unit fan: Manually rotate fan to verify free rotation

and insure that blower wheel is secured to the motor shaft. Be sure to remove any shipping supports if needed. DO NOT oil motors upon startup. Fan motors are pre-oiled at the factory. Check unit fan speed selection and compare to design requirements.

 Condensate line: Verify that condensate line is open

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: Insure 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.

 Cooling tower/boiler: Check equipment for proper set

points 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 set points 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.

NOTICE! Failure to remove shipping brackets from springmounted compressors will cause excessive noise, and could cause component failure due to added vibration.

SYSTEM CHECKOUT

 System water temperature: Check water temperature

for proper range and also verify heating and cooling set points 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 insure 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.

Unit Start-Up Procedure

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 8. During start-up checks, loop water temperature entering the heat pump should be between 60°F [16°C] and 95°F [35°C].

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 8. See controls description for details.

c. 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.

Refer to Table 9. 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.

Check air temperature drop across the air coil when compressor is operating. Air temperature drop should be between 15°F and 25°F [8°C and 14°C].

f. 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.

Refer to Table 9. 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.

Check air temperature rise across the air coil when

compressor is operating. Air temperature rise should be between 20°F and 30°F [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.

 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! 

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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

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, 1.5 gpm per ton [2.0 l/m per kW] is recommended as a minimum ﬂ ow. Minimum ﬂ ow rate for entering water temperatures below 50°F [10°C] is 2.0 gpm per ton [2.6 l/m per kW].

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 gpm per ton (3.9 l/m per kW) can produce water (or debris) velocities that can erode the heat exchanger wall and ultimately produce leaks.

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.

Condensate Drain

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 overﬂ ow.

Compressor

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

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.

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 ﬁ ns 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. 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 charts for pressures and temperatures. Verify that air and water ﬂ ow rates are at proper levels before servicing the refrigerant circuit.
