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-407c and HFC-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 HFC-410A.

 WARNING! 

WARNING! To avoid the release of refrigerant into the

atmosphere, the refrigerant circuit of this unit must be serviced only by technicians who meet local, state, and federal proﬁ ciency requirements.

 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.

Dimensions ar e inch es ( m m ).

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

 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.

 CAUTION! 

CAUTION! To avoid equipment damage, DO NOT use

these units as a source of heating or cooling during the construction process. The mechanical components and ﬁ lters will quickly become clogged with construction dirt and debris, which may cause system damage.

 WARNING! 

WARNING! 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.

Inspection -

check the shipment against the bill of lading. See ﬁ gure 1 for components. Make sure all units have been received. Inspect the packaging of each unit, and inspect each unit for damage. Ensure 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.

Upon receipt of the equipment, carefully

Pre-Installation Information

Storage -

packaging in a clean, dry area. Store chassis in an upright position at all times. Stack units at a maximum of 2 units high.

Store cabinets how they were shipped - vertical, keeping them on their pallets for protection. Do not stack multipacks. Store risers in secure area. ClimateMaster will not replace missing risers.

Unit Protection -

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. All openings in cabinet must be covered during all stages of construction. Physical damage and contamination may prevent proper start-up and may result in costly equipment clean-up.

Examine all pipes, ﬁ ttings, and valves before installing any of the system components. Remove any dirt or debris found in or on these components.

Prior to ﬂ ushing risers with water, be sure that the temperature in building will always be above freezing.

Pre-Installation -

Maintenance instructions are provided with each unit. The installation site chosen should include adequate service clearance around the unit. Before unit installation and start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check the system before operation.

Your installation may require additional, different sequence, or modiﬁ cation to steps in this IOM.

Equipment should be stored in its original

Cover units on the job site with either

7. A base vibration dampening pad is recommended to help eliminate transfer of vibration to the structure. If isolation pad was not ordered, obtain of 0.070” to

0.125” (1.5 to 3) thick pad and apply to the bottom of the cabinet.

8. For chassis shipped inside cabinet remove and discard 4 shipping bolts.

9. Remove inner panel (8 screws) and save for reinstallation after chassis is installed.

10. For standard cabinets remove and discard condensate pan shipping wire ties.

Prepare chassis for installation as follows:

1. Verify refrigerant tubing is free of kinks or dents and that it does not touch other tubes or unit parts as it passes over or through. Adjust if needed and separate with closed cell insulation.

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

3. If chassis is not installed in cabinet, store in original carton in a clean and dry location.

 WARNING! 

WARNING! To avoid damage from clogged coil surfaces,

clogged motor ventilation openings, seized fan blades and potential unit failure, DO NOT OPERATE UNIT without complete enclosure, supply grille, return air panel and ﬁ lter in place.

 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.

Prepare cabinet 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. Each cabinet has a tag to indicate the location to be installed.

3. Keep the cabinet openings and exposed sheet metal covered until installation is complete and all plastering, painting, etc. is ﬁ nished and cleaned.

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

5. Remove correct riser knockouts, slit insulation vertical down center (do not remove).

6. Repair any torn insulation with foil tape.

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.

Risers will have tag with ﬂ oor, riser number (if ﬁ lled out on EZ Order). Entire riser stacks can be assembled, pressure tested, ﬂ ushed, and ﬁ lled before setting cabinets. Use caution if ﬁ lled risers are in unconditioned space, prevent freezing. Do not construct walls until cabinets are set.

Description - Supply and return risers can be straight, transition up, transition down, bottom capped, or top capped. Drain risers can be straight, transition up, or top capped. All drain risers and extended range (operation below 60 ºF entering water temperature) supply and return risers need insulation. Repair or replace any damaged or missing insulation.

Type M has red identiﬁ cation marking (stripe running down the tube) and Type L (thicker wall) has blue identiﬁ cation marking. If tube is insulated pull back carefully to check color.

Shutoff and hose size for cabinet/chassis- ½” for D1 (09) and D2 (12); ¾” for D3 (15) and D4 (18); 1” for D5 (24), D6 (30), and D7 (36).

Supply riser is always closest to back corner of cabinet, return riser next, and drain riser in approx. middle of the cabinet. Risers are 9.25” (235) apart on centerline. See Figure 5.

 CAUTION! 

CAUTION! To ensure correct riser positioning and to

compensate for variations in ﬂ oor-to-ﬂ oor dimensions, do not allow the unit to unit riser joint to bottom out.

7. Insert expansion devices if required by plans.

8. Continue until complete riser stack is assembled.

9. Check all risers are correct diameter , type, valve size; correctly positioned; centered in slot; plumb from top to bottom; depth into swedge correct; runouts at correct height, and shutoff valve handles are parallel with the side of cabinet. (see Figure 2)

10. Braze all joints with high temperature alloy like Phoscopper or Silfos. (DO NOT use soft solder 50-50, 60-40 or 85-15; low temperature alloys are not acceptable for this application).

11. Must securely anchor riser stacks to building structure at least on one ﬂ oor. Typically at middle ﬂ oor and additional ﬂ oors as needed. Example: 40 ﬂ oors, anchor at 10, 20, and 30. Use expansion devices between anchors.

12. Remove temporary supports.

13. Check that risers did not drop. If stack dropped, jack up and add additional anchor support.

Secure Riser Stack to building structure so stack does not drop over time. Cabinet slots allow for 1.50” (38mm) maximum expansion and 1.50” (38mm) maximum contraction, use expansion devices if you exceed these values.

To facilitate cleaning and ﬂ ushing, install the hose kit at the end farthest from the pump and connect the ends of the hoses with the riser ﬂ ush adapter (Kit - AFL5751). Then open both valves before pumping fresh water through the system, close the valves when the system is clean. Remove the ﬂ ush adapter before installing the chassis.

Note: Refer to System Flushing Section of this manual for more information.

Install air vents in piping loop at highest accessible point as required to bleed the system of air accumulated

Misalignment found anytime including when cabinets are set, not using expansion devices if speciﬁ ed, or stack was not supported correctly is the sole responsibility of the installing contractor.

Cabinet Installation

1. Check plans that cabinet is correct for location, cabinet will have tag and data plate with information, including unit size, diameters of risers, and electrical data.

2. Remove riser KO’s (3) for your cabinet conﬁ guration (see ﬁ gure 2).

3. Cover supply and return openings with 4 pads. Slit with knife (see ﬁ gure 7).

4. Slide cabinet up to riser allow 1/4” to 1” (6 to 25mm) clearance.

5. Attach the cabinet assembly to the ﬂ oor on at least two sides using sheet metal angles. Additional anchorage may be provided by installing brackets at the top of the cabinet. a. Anchor built-in risers to the building structure

with at least one contact point. To accommodate vertical expansion and contraction DO NOT fasten risers rigidly within the unit.

b. Verify that unit shut-off valves are closed. DO NOT

OPEN VALVES until the system has been cleaned and ﬂ ushed.

For cabinets with chassis inside - remove 4 shipping screws, discard.

7. Remove inner panel (8 screws), save both.

Remove condensate pan shipping wire ties.

9. P-Trap Hose must be connected, lift drain pan, and clamp to riser stub and pan. If condensate hose must be rotated, loosen clamp on pan, rotate, and reclamp. Check condensate drain - clean pan if needed. Slowly pour 1 to 2 quarts (1 to 2 liters) of water into pan. Water should drain freely. Check for water in cabinet and on ﬂ oor. Repair if needed, Retest.

10.

Sheet metal ductwork should not be attached to the cabinet. A canvas-type ﬂ exible connection is recommended between the cabinet and the ductwork.

11. Optional Electric Heater – Single point power to unit.

cabinet) Position studs in front of cabinet and install frame in opening. Seal the gap between the cabinet and the frame. If fresh air motorized damper assembly is used, ﬁ eld fabricate and install duct from outside to frame opening. Assembly is installed later. See instructions with assembly. NOTICE! Allow for drywall thickness under frame front ﬂ ange. Must use damper motor assembly if fresh air is needed.

Optional Field Supplied Return Air Duct Installation

When return air is required to enter the unit through openings in a stud wall, supply and ﬁ eld install an optional duct. Seal duct against the return air opening with foam. Ensure that all air entering the unit passes through the

ﬁ lter and refrigerant-to-air coil. Note: Chassis must be removable for service.

Drywall Installation

For best sound attenuation, it is recommended not to attach drywall to cabinet. Install studs and drywall using conventional construction methods. Secure drywall to studs with low proﬁ le, pan-head sheet metal screws. Drywall can be attached directly to cabinet (except in places indicated in Fig 1), front of cabinet requires double thickness. Must not be fastened to drain pan edges or control box enclosure. Do not attach studs to cabinet. Do not install drywall using adhesive alone.

See typical construction ﬁ gures to determine stud layouts and dimension from cabinet to ﬁ nished wall. Vacuum all drywall dust and construction debris from cabinet insulation, drain pans and blower discharge plenum after cutting out supply. Insulation should be placed between the drywall and the cabinet for sound attenuation.

When drywall installation is complete, cover all cabinet openings and exposed sheet metal. (Cardboard from unit shipping cartons can be used). Do not allow paint or wall texture over-spray to contact insulation, sheet metal, coil, fan or other unit components. Warranties are void if paint or other foreign debris is allowed to contaminate internal unit components.

Water-Loop Heat Pump Applications

Commercial Water Loop Applications - Commercial

systems typically include a number of units connected to a common piping system with a cooling tower and boiler. 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.

Teﬂ on tape thread sealant is recommended to minimize internal fouling of the heat exchanger. Do not over tighten connections and route piping so as not to interfere with service or maintenance access. Hose kits are available from ClimateMaster. 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.

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.

Water loop heat pump (cooling tower/boiler) systems typically utilize a common loop, maintained between 60 and 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.

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 inground 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.

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.

Antifreeze - If any liquid ﬂ uid or piping is exposed to unconditioned ambient below 42°F (5.5 C), antifreeze must be added. If the liquid ﬂ uid entering the heat pump is 50°F (10°C) or below, calculate the leaving heat pump temperature (shown in submittal on performance data selection notes section). Using the lowest temperature leaving the heat pump, must protect system 15°F (8°C) lower. IE: if temperature leaving the heat pump is 35°F subtract 15°F = 20°F protection required, if Methanol is used the system would require 16% mix by volume. Antifreeze is available in alcohol and glycols, contact local sales ofﬁ ce for the best type for your system and area. Following must be considered safety, thermal performance, corrosiveness, local codes, stability, convenience, and cost.

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.

Low Water Temperature Cutout Setting - CXM Control

When antifreeze is selected, the LT1 jumper (JW3) should be clipped to select the low temperature (antifreeze

10.0°F [-12.2°C]) setpoint and avoid nuisance faults (see “Low Water Temperature Cutout Selection” in this manual). Note: Low water temperature operation

requires extended range equipment. Table 2: Antifreeze Percentages by Volume

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 of f 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 temperatur e 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 4 for water quality guidelines. The unit can be ordered with either a copper or cupro-nickel water heat exchanger. Consult T able 4 for r ecommendations. 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.

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 return line to prevent mineral precipitation during the of fcycle. Pilot operated slow closing valves are recommended to reduce water hammer. If water hammer persists, a miniexpansion tank can be mounted on the piping to help absorb the excess hammer shock. Ensure that the total ‘V A’ 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 15V A.

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 return line. Measure the pressur e dr op thr ough the unit heat exchanger, and determine ﬂ ow rate from. Since the pr essur e 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 fr om the ball valve located on the discharge line. Slightly closing the valve will spread the pressure dr op 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, CXM/DXM JW3 Jumper (LT1) should never be clipped to avoid freeze damage to the unit, and voiding your warranty. See “Low Water Temperature Cutout Selection” in this manual for details on the low limit setting.

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 fr equency of heat pump maintenance and may shorten life expectancy.

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

Blower Speed Selection – Units with PSC or ECM-CT Motor

PSC (Permanent Split Capacitor) blower fan speed can be changed by moving the speed tap wires on the fan motor terminal block. See Figure 12. Note: Check blower table 5a-5g, must maintain minimum CFM for your external static.

Blower Speed Selection – Units with ECM-CV Motor

CFM can be changed from default settings by using ATC32U03C Thermostat or ACDU03C service tool with 11B0100N27 Harness. Use information in Table 5 to set CFM for your static.

Special Note for AHRI Testing: To achieve rated airﬂ ow for AHRI testing purposes on all PSC products - TSL09 and 12 use high speed tap for heating and medium tap for cooling. All other models use high speed tap for both. When the heat pump has experienced less than 100 operational hours and the coil has not had sufﬁ cient time to be “seasoned”, it is necessary to clean the coil with a mild surfactant such as Calgon to remove the oils left by manufacturing processes and enable the condensate to properly “sheet” off of the coil.

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.

208 Volt Operation - All commercial 208-230 Volt units are factory wired for 208 Volt operation. If supply voltage is 230V, then the transformer must be rewired to the 230V tap as illustrated on the wiring diagram by switching the red (208V) and the orange (230V) wires at the contactor terminal.

Electrical Wiring - Low Voltage

Thermostat Connections - The thermostat can be

spliced or wired directly to the CXM or DXM2 board. See Unit Wire Diagram. Review the appropriate thermostat AOM (Application, Operation and Maintenance) manual.

Wall Sensors (ASW) for MPC or LON - Connections are made to DDC controller, see Unit Wire Diagram.

Cabinets with MPC or LON (model digit 5 is C,D,L,M or U) requires ﬁ eld to clip JW1 jumper on CXM or DXM2 board in chassis.

Low Water Temperature Cutout Selection - The CXM/

DXM2 control allows the ﬁ eld selection of low water (or water-antifreeze solution) temperature limit by clipping jumper JW3, which changes the sensing temperature associated with thermistor LT1. Note that the LT1 thermistor is located on the refrigerant line between the coaxial heat exchanger and expansion device (TXV). Therefore, LT1 is sensing refrigerant temperature, not water temperature, which is a better indication of how water ﬂ ow rate and temperature is affecting the refrigeration circuit.

The factory setting for LT1 is for systems using water no lower than 50ºF (10ºC), boiler tower or open loop. Water temperature below 50ºF (10ºC) (extended range) applications must use antifreeze (most ground loops), jumper JW3 must be clipped as shown in Figure 8. Lowest refrigerant temperature, LT1 can sense without faulting off is, with LT1 unclipped - 30ºF (-1ºC) and clipped - 10ºF (-12ºC). All ClimateMaster units operating with entering water temperatures below 59°F [15°C] must include the optional water/refrigerant circuit insulation package to prevent internal condensation.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Installation of Optional Wall-Mounted Thermostat - The unit can be furnished with a 24-volt surface mounted ACO or MCO control circuit or a remote 24-volt ACO or MCO thermostat. A typical ﬁ eld connection diagram is shown in Figure 14. Refer to instructions provided with remote thermostat for wiring instructions.

Thermostat Installation

 WARNING! 

WARNING! 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. Use of eight wire, colorcoded, low-voltage cable is recommended.

Note: Your thermostat may require fewer than 8 connections, 8 wires allow future upgrading thermostat. Tape off unused wires.

Table 6 below lists recommended wire sizes and lengths to install the thermostat. The total resistance of lowvoltage wiring must not exceed 1 ohm. Any resistance in excess of 1 ohm may cause the control to malfunction because of high voltage drop.

A91558 Series Thermostats have 6” (152) pigtail ending with 9-pin Molex. This allows an easy connection to either surface mount or remote with factory whip option.

AT Series Thermostats have to be wired to screw terminals under the cover.

 WARNING! 

WARNING! Under no circumstances should any part of the

hose itself be gripped or twisted by hand, pliers, channel locks or any other tool. Leakage or bursting may occur! Always use a back-up wrench when tightening the hose.

Step 4: Chassis Installation - Check condensate pan is free and on 4 rubber grommets.

Install the Chassis as follows:

Washers

Step 3: Attach AHH or AHU hoses to the Chassis. Check the swivel ends of the hoses (Figure 22). Washers must be in the hose for water tight connection. Slide the chassis part way into the cabinet. Match the WATER IN (supply) hose to the WATER IN tube on the chassis and the WATER OUT (Return) hose to the WATER OUT tube. Position hose toward chassis, use gentle loop- see bend radii Table 7. Hand tighten hose.

Table 7: Metal Hose Minimum Bend Radii

Hose Diameter Minimum Bend Radii

1/2" (12.7) 2-1/2" (64) 3/4" (19.1) 4" (102)

1" (25.4) 5-1/2" (140)

1-1/4" (31.8) 6-3/4" (170)

1. Slide Chassis fully into cabinet. Check hose for kinks, do not allow less than minimum bend radius (see table 7), pull chassis partway out, loosen hose and reposition hose if needed, retighten.

2. Verify that both the shut-off valves are closed. See Fig. 21. (handle horizontal)

3. Verify riser stack has been pressure tested, and all leaks have been repaired.

 WARNING! 

WARNING! Do Not open valves to chassis until system has

ﬂ ushed and purged of air!

 IMPORTANT! 

IMPORTANT! After the system has been ﬁ lled and system

pump is started, all connections should be rechecked for water leaks. ClimateMaster WILL NOT be responsible or liable for damage caused by water leaks at any ﬁ eld water connections!

Do not bend hoses at less than the minimum bend radius for the hose selected. Less than 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.

 CAUTION! 

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

 CAUTION! 

CAUTION! Piping must comply with all applicable codes.

 CAUTION! 

CAUTION! Corrosive system water requires corrosion

resistant ﬁ ttings and hoses, and may require water treatment.

4. Flush system following the procedure in Preparation for Start-up Section of this manual.

5. When the system is clean and ﬂ ushed, open both water shut off valves and check piping for leaks. Repair all leaks before continuing.

6. Complete electrical connections between cabinet and chassis. Connect wire harnesses hanging down from under side of control box to chassis connections. (See Figure 23). Check that Molex connectors are snapped together, pull gently on connector - do not pull on wires.

Start-Up Preparation

System Cleaning and Flushing - Cleaning and ﬂ ushing the unit is the single most important step to ensure proper start-up and continued efﬁ cient operation of the system. Follow the instructions below to properly clean and ﬂ ush the system: Do not ﬂ ush through the chassis. Coax can get plugged and water ﬂ ow will be

reduced, causing poor performance and may cause LT1 sensor to trip.

 WARNING! 

WARNING! To prevent injury or death due to electrical shock

or contact with moving part, open unit disconnect before servicing unit.

1. Verify that electrical power to the unit is disconnected.

2. Verify that supply and return riser service valves are closed at each unit.

3. Fill the system with water. Bleed all air from the system but do not allow the system to over ﬂ ow. Check the system for leaks and make any required repairs.

4. Adjust the water and air level in the expansion tank.

5. With strainers in place, (ClimateMaster recommends a strainer with a #20 stainless steel wire mesh) start the pumps. Systematically check that all of the air is bled from the system.

6. Verify that make-up water is available and adjusted to properly replace any space remaining when all air is evacuated. Check the system for leaks and make any additional repairs required.

7. Set the boiler to raise the loop temperature to approximately 85°F [29.4°C]. Open the drain at the lowest point in the system. Verify that make-up water replacement rate equals rate of bleed. Continue to bleed the system until the water appears clean or for at least three hours whichever is longer.

8. Completely drain the system.

6. Repeat ﬂ ushing procedure for each set of risers in the building.

7. Reﬁ ll the system and add in a proportion of trisodium phosphate approximately one pound per 150 gallons [0.4kg per 500 liters] of water. Reset the boiler to raise the loop temperature to about 100°F [37.8°C].

8. Circulate the solution for between 8 to 24 hours. At the end of this period, shut off the circulating pump and drain the solution. Repeat system cleaning if desired.

9. Open the supply and return riser service valves at each unit. Reﬁ ll the system and bleed off all air.

10. Test the system pH with litmus paper. The system water should have a pH of 6 to 8.5. Add chemicals as appropriate to maintain pH levels.

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

Figure 25: Typical piping arrangement for ﬂ ushing risers.

Flush risers as follows: (Refer to Figure 25).

1. Remove cabinet ﬁ lter and front inner panel. Save these for reinstallation after the chassis is installed.

2. Close shut-off valves at each cabinet on the riser except the shut-off valve on the top ﬂ oor.

3. At the top ﬂ oor, install the hose kit and connect the ends of the hoses with the factory riser ﬂ ush adapter from AFL5751. For sweat shutoffs, one AHU hose can be used.

4. Flush solution through supply riser. Note: The solution passes through the top ﬂ oor connection down the return riser.

5. When the building has more than 10 ﬂ oors, connect the supply and return runouts on the top two ﬂ oors to divide the water ﬂ ow and reduce pressure drop at the pump.

 CAUTION! 

CAUTION! Do Not use "Stop-Leak" or any similar chemical

agent in this system. Addition of these chemicals to the loop water can foul the system and can inhibit unit operation.

 CAUTION! 

CAUTION! To avoid possible damage to piping systems

constructed of plastic piping, DO NOT allow loop temperature to exceed 110°F [43.3°C].

CXM Control

CXM Control - For detailed control information, see

CXM Application, Operation and Maintenance (AOM) manual (part # 97B0003N12).

Field Selectable Inputs - Test mode: Test mode allows the service technician to check the operation of the control in a timely manner. At board, momentarily shorting the test terminals or externally, momentarily push test button (See Fig 10), 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 or holding button 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.

Water coil low temperature limit setting: Jumper 3 (JW3LT1 Low Temp) provides ﬁ eld selection of temperature limit setting for LT1 of 30°F or 10°F [-1°F or -12°C] (refrigerant temperature).

Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].

Air coil low temperature limit setting: Jumper 2 (JW2LT2 Low Temp) provides ﬁ eld selection of temperature limit setting for LT2 of 30°F or 10°F [-1°F or -12°C] (refrigerant temperature). Note: This jumper should

only be clipped under extenuating circumstances, as recommended by the factory.

Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].

Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides ﬁ eld selection of the alarm relay terminal AL2 to be jumpered to 24VAC or to be a dry contact (no connection).

Not Clipped = AL2 connected to R. Clipped = AL2 dry contact (no connection).

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

provides ﬁ eld selection to disable the UPS feature.

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.

1.1 - Unit Performance Sentinel (UPS) disable: DIP Switch

1.1 provides ﬁ eld selection to disable the UPS feature. On = Enabled. Off = Disabled.

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

1.3 - Thermostat type (heat pump or heat/cool): DIP 1.3 provides selection of thermostat type. Heat pump or heat/cool thermostats can be selected. When in heat/ cool mode, Y1 is the input call for cooling stage 1; Y2 is the input call for cooling stage 2; W1 is the input call for heating stage 1; and O/W2 is the input call for heating stage 2. In heat pump mode, Y1 is the 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 LT1 is above the temperature speciﬁ ed by the setting of DIP 1.8. Below DIP 1.8 setting, the compressor is not used and the control goes into emergency heat mode, staging on EH1 and EH2 to provide heating. On = normal. Off = Boilerless operation.

1.8 - Boilerless changeover temperature: DIP 1.8 provides selection of boilerless changeover temperature setpoint.

Note that the LT1 thermistor is sensing refrigerant temperature between the coaxial heat exchanger and the expansion device (TXV). 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].

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

2.1 - Accessory1 relay personality: DIP 2.1 provides selection of ACC1 relay personality (relay operation/ characteristics). See table 9 for description of functionality.

2.2 - Accessory1 relay personality: DIP 2.2 provides selection of ACC 1 relay personality (relay operation/ characteristics). See table 9 for description of functionality.

2.3 - Accessory1 relay personality: DIP 2.3 provides selection of ACC 1 relay options. See table 11 for description of functionality.

2.4 - Accessory2 relay personality: DIP 2.4 provides selection of ACC 2 relay personality (relay operation/ characteristics). See table9 for description of functionality.

Safety Features - CXM/DXM2 Controls

Safety Features – CXM/DXM 2 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 featur es 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 (DXM2 board) or by going into test mode (CXM board). Note: LT1/LT2 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 2 is conﬁ gured for heat pump thermostat type (DIP 1.3), emergency heat will become active if O/ W2 is energized.

For LED fault codes and alarm relay output for CXM see table 9 and DXM 2 see table 10. High pressure switch: When the high pressur e switch

opens due to high refrigerant pressures, the compr essor relay is de-energized immediately since the high pressur e 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). Note: For units with motorized water valve, one high pressure water switch is in series with refrigerant high pressure switch and will cause fault if pressur e is 300 PSI (reset at 240 PSI). Low pressure switch: The low pressur e 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 pressur e (loss of charge) fault. The low pressure switch input is

bypassed for the initial 120 seconds of a compressor run cycle. Water coil low temperature (LT1): The LT1 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 LT1 fault. The LT1 input is bypassed for the initial 120 seconds of a compressor run cycle. LT1 is set at the factory for one try. Therefore, the control will go into lockout mode once the LT1 fault has occurred. Air coil low temperature (LT2): The LT2 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 LT2 fault. The LT2 input is bypassed for the initial 60 seconds of a compressor run cycle. LT2 is set at the factory for one try. Therefore, the control will go into lockout mode once the LT2 fault has occurred. 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. 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/DXM2 is in over/under voltage shutdown for 15 minutes, the alarm relay will close. 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, LT2

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

b. In cooling mode with compressor energized, LT1

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

c. In cooling mode with compressor energized, LT2 is

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

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

Swapped LT1/LT2 thermistors: During test mode, the control monitors to see if the LT1 and LT2 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

LT1 sensor is colder than the LT2 sensor, or:

b. The compressor is on in the heating mode and the

LT2 sensor is colder than the LT1 sensor. ESD (DXM2 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.

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).

 CAUTION! 

CAUTION! Do not restart units without inspection and

remedy of faulting condition. Equipment damage may occur.

The green status LED and red fault LED on the DXM 2 board advise the technician of the current status of the DXM 2 control. The status LED will indicate the current mode that the DXM 2 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.

CXM/DXM 2 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.

Unit and System Checkout

 CAUTION! 

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

system, do not allow temperatures to exceed 1 10ºF (43ºC).

Note: The manufacturer strongly recommends all piping connections, both internal and external to the unit, be pressure tested by an appropriate method prior to any ﬁ nishing of the interior space or before access to all connections is limited. Test pressure may not exceed the maximum allowable pressure for the unit and all components within the water system. The manufacturer will not be responsible or liable for damages from water leaks due to inadequate or lack of a pressurized leak test, or damages caused by exceeding the maximum pressure rating during installation.

BEFORE POWERING SYSTEM, please check the following:

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 T able 3).

 System ﬂ ushing: Verify that all hoses ar e connected end

to end when ﬂ ushing to ensure that debris bypasses the unit heat exchanger, water valves and other components. Water used in the system must be potable quality initially and clean of dirt, piping slag, and strong chemical cleaning agents. Verify that all air is pur ged fr om the system. Air in the system can cause poor operation or system corrosion.

 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.

UNIT CHECKOUT

 Balancing/shutoff valves: Ensure 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: Ensure that transformer has

the properly selected voltage tap. Commercial 208230V units are factory wired for 208V operation unless speciﬁ ed otherwise.

 Entering water and air: Ensure that entering water and

air temperatures are within operating limits of Tables 12 & 13.

 Low water temperature cutout: Verify that low water

temperature cut-out on the CXM/DXM2 control is properly set.

 Unit fan: Manually rotate fan to verify free rotation

and ensure that blower wheel is secured to the motor shaft. Be sure to remove any shipping supports if needed. DO NOT oil motors upon start-up. 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: Ensure that ﬁ lter is clean and

accessible. Clean air coil of all manufacturing oils.

 Unit controls: Verify that CXM or DXM2 ﬁ eld selection

options are properly set.

Unit Start-Up Procedures

Unit Start-up Procedure

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

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

3. Balance air ﬂ ow at registers.

4. Room temperature should be within the minimummaximum ranges of Tables 12 & 13. During start-up checks, loop water temperature entering the heat pump should be between 60°F [16°C] and 95°F [35°C].

5. Two factors determine the operating limits of ClimateMaster heat pumps, (a) return air temperature, and (b) water temperature. When any one of these factors is at a minimum or maximum level, the other factor must be at normal level to ensure 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 are eliminated in the test mode.

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.

d. Refer to Tables 12 & 13. 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.

e. 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.

d. Check the temperature difference between

entering and leaving water, see table 14. If

temperature is within range, proceed with the test. If temperature is outside of the operating range, check refrigerant pressures, see table 15A

- D.

e. 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. Inner panel and ﬁ lter must be on chassis to block air from bypassing air coil. Bypass air will cause unit to fault off.

8. 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 ensure proper diagnosis and repair of the equipment.

9. When testing is complete,

a. Set thermostat to owners b. Re-assemble all parts.

10. Save start up log sheet for future reference.

11. 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 and DXM2 sections 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.
