PRODUCT DESIGN LOCATION & CLEARANCES NOTE: To ensure proper condensate drainage, unit must be installed in a level position. In installations where the unit is installed above ground level and not serviceable from the ground (Example: Roof Top installations) the installer must provide a service platform for the service person with rails or guards in accordance with local codes or ordinances. 48” MIN.
PRODUCT DESIGN The outdoor fan motor and the indoor blower motor are single phase capacitor type motors, except the 5 ton models which use a EEM indoor blower motor. • These scroll compressors use POE or polyolester oil which is NOT compatiable with mineral oil based lubricants like 3GS. POE oil must be used if additional oil is required. Air for condensing (cooling) is drawn through the outdoor coil by a propeller fan, and is discharged vertically out the top of the unit.
PRODUCT DESIGN WARNING TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY OR FIRE, USE ONLY COPPER CONDUCTORS. LINE VOLTAGE WIRING Power supply to the unit must be N.E.C. Class 1, and must comply with all applicable codes. The unit must be electrically grounded in accordance with the local codes or, in their absence, with the latest edition of the National Electrical Code, ANSI/NFPA No. 70, or in Canada, Canadian Electrical Code, C22.1, Part 1.
SYSTEM OPERATION COOLING The refrigerant used in the system is R-410A. It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125. The boiling point at atmospheric pressure is -62.9°F. A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warmer to a cooler body. Under lower pressure, a refrigerant will absorb heat and vaporize at a low temperature.
SYSTEM OPERATION Heat Pump Units On a call for first stage heat, the contacts of the room thermostat close. This energizes terminals R to Y and R to G, the low voltage circuit to the contactor is completed starting the compressor and outdoor fan motor. This also energizes the indoor blower through the normally open contacts of the EBTDR after a 7 second on delay on models equipped with PSC type blower motors, and instantly on models equipped with EEM blower motors.
SYSTEM OPERATION Typical Package Cooling Indoor Coil Outdoor Coil Chatleff Orifice Assy Restrictor Orifice Assembly in Cooling Operation In the cooling mode the orifice is pushed into its seat forcing refrigerant to flow through the metered hole in the center of the orifice.

SERVICING S-1 CHECKING VOLTAGE WARNING 1. Remove doors, control panel cover, etc. from unit being tested. With power ON: WARNING LINE VOLTAGE NOW PRESENT. 2. Using a voltmeter, measure the voltage across terminals L1 and L2 of the contactor for single phase units, and L3, for 3 phase units. 3. No reading - indicates open wiring, open fuse(s) no power or etc. from unit to fused disconnect service. Repair as needed. 4. With ample voltage at line voltage connectors, energize the unit. 5.
SERVICING 3. Set fan selector switch at thermostat to "ON" position. WARNING 4. With voltmeter, check for 24 volts at wires C and G. 5. No voltage, indicates the trouble is in the thermostat or wiring. 6. Check the continuity of the thermostat and wiring. Repair or replace as necessary. S-3B COOLING ANTICIPATOR The cooling anticipator is a small heater (resistor) in the thermostat. During the "off" cycle it heats the bimetal element helping the thermostat call for the next cooling cycle.
SERVICING SINGLE PHASE 3. If not as in steps 1 and 2, replace EBTDR. 1. Disconnect the wire leads from the terminal (T) side of the contactor. Checking EBTDR Contact Operation With power on: 2. With power ON, energize the contactor. WARNING LINE VOLTAGE NOW PRESENT. WARNING 1. Set the thermostat to the fan "on" position. LINE VOLTAGE NOW PRESENT. 2. Check for 24 volts at the C and G terminals of the EBTDR. 3. If no voltage present, check fan circuit from thermostat.
SERVICING With power ON: WARNING LINE VOLTAGE NOW PRESENT. 3. Apply 240 volts to coil terminals 1 and 3. 4. Using a VOM, check for 240 volts from terminals 3 and 1 of relay. Should read 240 volts. In no voltage, check wiring from heater kit to relay. If voltage present, proceed to step 5. WARNING LINE VOLTAGE NOW PRESENT. 3. Start the system and place a piece of cardboard in front of the condenser coil, raising the condensing pressure. 4. Check pressure at which the high pressure control cutsout. 5.
SERVICING A switching device must be wired in series with the capacitor to remove it from the electrical circuit after the compressor starts to run. Not removing the start capacitor will overheat the capacitor and burn out the compressor windings. These capacitors have a 15,000 ohm, 2 watt resistor wired across its terminals.
SERVICING S-16 CHECKING MOTORS S-16A CHECKING FAN AND BLOWER MOTOR WINDINGS (PSC MOTORS) Applies only to units with PSC Motors The auto reset fan motor overload is designed to protect the motor against high temperature and high amperage conditions by breaking the common circuit within the motor, similar to the compressor internal overload. However, heat generated within the motor is faster to dissipate than the compressor, allow at least 45 minutes for the overload to reset, then retest.
SERVICING Ignition of the discharge can also occur at the venting terminal or inside the compressor, if there is sufficient contaminant air present in the system and an electrical arc occurs as the terminal vents. Ignition cannot occur at the venting terminal without the presence of contaminant air, and cannot occur externally from the venting terminal without the presence of an external ignition source.
SERVICING 3. If a ground is indicated, then carefully remove the compressor terminal protective cover and inspect for loose leads or insulation breaks in the lead wires. 4. If no visual problems indicated, carefully remove the leads at the compressor terminals. Carefully retest for ground, directly between compressor terminals and ground. 5. If ground is indicated, replace the compressor.
SERVICING S-21 CHECKING REVERSING VALVE AND SOLENOID Occasionally the reversing valve may stick in the heating or cooling position or in the mid-position. When stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. An increase in the suction line temperature through the reversing valve can also be measured.
SERVICING WARNING 4. Clean the inside of all new tubing to remove oils and pipe chips. 5. When brazing, sweep the tubing with dry nitrogen to prevent the formation of oxides on the inside surfaces. 6. Complete any repair by replacing the liquid line drier in the system, evacuate and charge. At any time the system has been open for repair, the factory installed liquid line filter drier must be replaced. 2. Visually inspect the heater assembly for any breaks in the wire or broken insulators.
SERVICING NOTE: Refrigerant hoses must be equipped with dill valve depressors or special adaptor used. Open the valve on the cylinder and manifold and allow the pressure to build up within the system. Check for and handle leaks, as described above. After the test has been completed, remove and capture the leak test refrigerant. LOW SIDE GAUGE AND VALVE HIGH SIDE GAUGE AND VALVE S-102 EVACUATION WARNING This is the most important part of the entire service procedure.
SERVICING S-103 CHARGING WARNING 1. Using a quality set of charging scales, weigh the proper amount of refrigerant for the system. Allow liquid refrigerant only to enter the high side. 2. After the system will take all it will take, close the valve on the high side of the charging manifold. 3. Start the system and charge the balance of the refrigerant through the low side.
SERVICING The condition of the valves or scroll flanks is checked in the following manner. 1. Attach gauges to the high and low side of the system. 2. Start the system and run a Cooling Performance Test. If the test shows⇒ Below normal high side pressure. ⇒ Above normal low side pressure. ⇒ Low temperature difference across coil. ⇒ Low amp draw at compressor. -and the charge is correct. The compressor is faulty - replace the compressor.
SERVICING 5. The difference between the thermometer reading and pressure to temperature conversion is the amount of subcooling. Subcooling Formula = Sat. Liquid Temp. - Liquid Line Temp. EXAMPLE: a. Liquid Line Pressure = 417 b. Corresponding Temp. °F. = 120° c. Thermometer on Liquid line = 109°F. To obtain the amount of subcooling, subtract 109°F from 120°F. The difference is 11° subcooling. See the specification sheet or technical information manual for the design subcooling range for your unit.

SERVICING S-115 COMPRESSOR BURNOUT 4. Braze all joints, leak test, evacuate, and recharge system. When a compressor burns out, high temperature develops causing the refrigerant, oil and motor insulation to decompose forming acids and sludge. 5. Start up the unit and record the pressure drop across the drier. If a compressor is suspected of being burned-out, attach a refrigerant hose to the liquid line dill valve and properly remove and dispose of the refrigerant.
SERVICING S-200 CHECKING EXTERNAL STATIC PRESSURE The minimum and maximum allowable duct static pressure is found in the Technical Information Manual. Too great of an external static pressure will result in insufficient air that can cause icing of the coil, whereas too much air can cause poor humidity control, and condensate to be pulled off the evaporator coil causing condensate leakage. Too much air can cause motor overloading and in many cases this constitutes a poorly designed system.
