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.
PRODUCT DESIGN Air for condensing (cooling) is drawn through the outdoor coil by a propeller fan, and is discharged vertically out the top of the unit. The outdoor coil is designed for .0 static. No additional restriction (ductwork) shall be applied. Conditioned air is drawn through the filter(s), field installed, across the evaporator coil and back into the conditioned space by the indoor blower.
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.
SYSTEM OPERATION *PC/*PH14[24-60]M41* When auxiliary electric heaters are used, a two stage heating single stage cooling thermostat would be installed. frost cycle is not terminated due to the sensor temperature, a twelve minute override interrupts the unit’s defrost period. Should the second stage heating contacts in the room thermostat close, which would be wired to W1 at the unit low voltage connections, this would energize the coil(s) of the electric heat contactor(s)/sequencer(s) .

SERVICING S-1 CHECKING VOLTAGE WARNING Three phase units require a balanced 3 phase power supply to operate. If the percentage of voltage imbalance exceeds 3% the unit must not be operated until the voltage condition is corrected. Max. Voltage Deviation From Average Voltage X 100 Average Voltage % Voltage = Imbalance To find the percentage of imbalance, measure the incoming power supply. L1 - L2 = 240V Avg. V = 710 = 236.7 L1 - L3 = 232V 1. Remove doors, control panel cover, etc.
SERVICING S-2 CHECKING WIRING WARNING 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. This prevents the room temperature from rising too high before the system is restarted.
SERVICING S-4 CHECKING TRANSFORMER AND CONTROL CIRCUIT A step-down transformer (208/240 volt primary to 24 volt secondary) is provided with each package unit. This allows ample capacity for use with resistance heaters. S-8 CHECKING CONTACTOR CONTACTS WARNING DISCONNECT POWER SUPPLY BEFORE SERVICING. SINGLE PHASE WARNING 1. Disconnect the wire leads from the terminal (T) side of the contactor. 2. With power ON, energize the contactor. WARNING LINE VOLTAGE NOW PRESENT. 1.
SERVICING T3 T2 T1 4. Start the system and place a piece of cardboard in front of the condenser coil, raising the condensing pressure. 5. Check pressure at which the high pressure control cutsout.
SERVICING These capacitors have a 15,000 ohm, 2 watt resistor wired across its terminals. The object of the resistor is to discharge the capacitor under certain operating conditions, rather than having it discharge across the closing of the contacts within the switching device such as the Start Relay, and to reduce the chance of shock to the servicer. See the Servicing Section for specific information concerning capacitors.
SERVICING S-16D CHECKING EEM (ENERGY EFFICIENT MOTOR) MOTORS The EEM Motor is a one piece, fully encapsulated, 3 phase brushless DC (single phase AC input) motor with ball bearing construction. The EEM features an integral control module. Note: The GE TECMate will not operate the currently used EEM motor. 1. Using a voltmeter, check for 230 volts to the motor connections L and N. If 230 volts is present, proceed to step 2. If 230 volts is not present, check the line voltage circuit to the motor. 2.
SERVICING S-17A RESISTANCE TEST S-17B GROUND TEST Each compressor is equipped with an internal overload. If fuse, circuit breaker, ground fault protective device, etc., has tripped, this is a strong indication that an electrical problem exists and must be found and corrected. The circuit protective device rating must be checked and its maximum rating should coincide with that marked on the equipment nameplate. The line break internal overload senses both motor amperage and winding temperature.
SERVICING S-17D OPERATION TEST S-18 TESTING CRANKCASE HEATER If the voltage, capacitor, overload and motor winding test fail to show the cause for failure: Note: Not all compressors use crankcase heaters. The crankcase heater must be energized a minimum of twentyfour (24) hours before the compressor is operated. WARNING Crankcase heaters are used to prevent migration or accumulation of refrigerant in the compressor crankcase during the off cycles and prevents liquid slugging or oil pumping on start up.
SERVICING S-21 CHECKING REVERSING VALVE AND SOLENOID 7. Using VOM check for voltage across "W" & "C" terminals on the board. You should read 24 volts. Occasionally the reversing valve may stick in the heating or cooling position or in the mid-position. 8. If not as above, replace control board. 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.
SERVICING S-52 CHECKING HEATER ELEMENTS Optional electric heaters may be added, in the quantities shown in the spec sheet for each model unit, to provide electric resistance heating. Under no condition shall more heaters than the quantity shown be installed. 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.
SERVICING S-102 EVACUATION WARNING REFRIGERANT UNDER PRESSURE! FAILURE TO FOLLOW PROPER PROCEDURES MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH. LOW SIDE GAUGE AND VALVE 800 PSI RATED HOSES CHARGING CYLINDER AND SCALE This is the most important part of the entire service procedure. The life and efficiency of the equipment is dependent upon the thoroughness exercised by the serviceman when evacuating air (non-condensable) and moisture from the system.
SERVICING S-103 CHARGING WARNING Final Charge Adjustment The outdoor temperature must be 60°F or higher. Set the room thermostat to COOL, fan switch to AUTO, and set the temperature control well below room temperature. After system has stabilized per startup instructions, compare the operating pressures and outdoor unit amp draw to the numbers listed in the technical manual. If pressures and amp draw are too low, add charge. If pressures and amp draw are too high, remove charge.
SERVICING S-105 THERMOSTATIC EXPANSION VALVE S-107 UNDERFEEDING The expansion valve is designed to control the rate of liquid refrigerant flow into an evaporator coil in exact proportion to the rate of evaporation of the refrigerant in the coil. The amount of refrigerant entering the coil is regulated since the valve responds to temperature of the refrigerant gas leaving the coil (feeler bulb contact) and the pressure of the refrigerant in the coil.

SERVICING NOTE: To adjust superheat, turn the valve stem clockwise to increase and counter clockwise to decrease. b. If subcooling is low and superheat is high, add charge to raise subcooling to 5 to 7 ºF then check superheat. c. If subcooling and superheat are high, adjust TXV valve to 15 to 18ºF superheat, then check subcooling. d. If subcooling is high and superheat is low, adjust TXV valve to 15 to 18ºF superheat and remove charge to lower the subcooling to 5 to 7 ºF.
SERVICING S-114 NON-CONDENSABLES Check for non-condensables. 1. Shut down the system and allow the pressures to equalize for a minimum of 15 minutes. 2. Take a pressure reading. 3. Compare this pressure to the temperature of the coldest coil since this is where most of the refrigerant will be. If the pressure indicates a higher temperature than that of the coil temperature, non-condensables are present. To remove the non-condensables. 1. Remove the refrigerant charge. 2.
SERVICING S-200 CHECKING EXTERNAL STATIC PRESSURE Temperature rise is related to the BTUH output of the unit and the amount of air (CFM) circulated over the indoor coil. The minimum and maximum allowable duct static pressure is found in the Technical Information Manual. All units are designed for a given range of temperature increase. This is the temperature of the air leaving the unit minus the temperature of the air entering the unit.
