F AN MOTOR SWITCH, ON-OFF Line side SOLID ST A TE RELA Y Load side LED indicates contacts closed when lit F AN MOTOR A 230 volt single phase permanent split capacitor motor is used to drive the evaporator blower and condenser fan. A running capacitor is wired across the start and run terminals of the motor .
RANGE: Thermostat (Part No. 618-225-02) 60 ° F ( ± 2 ° ) to 90 ° F( ± 4 ° ) SENSING BULB LOCA TION THERMOST A T A cross ambient thermostat is used to maintain the desired comfort level. The thermostat reacts only to a change in temperature at the bulb location.
• R-410A pressure is approximately 60% higher than R-22 pressure. • R-410A cylinders must not be allowed to exceed 125 F , they may leak or rupture.
Proper refrigerant charge is essential to proper unit operation. Operating a unit with an improper refrigerant charge will result in reduced performance (capacity) and/or effi ciency . Accordingly , the use of proper charging methods during servicing will insure that the unit is functioning as designed and that its compressor will not be damaged.
3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 200 microns or less. 6. Weigh in refrigerant with the proper quantity of R-410A refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut.
Underchar ged R efrigerant Systems An undercharged system will result in poor performance (low pressures, etc.) in both the heating and cooling cycle. Whenever you service a unit with an undercharge of refrigerant, always suspect a leak. The leak must be repaired before charging the unit.
R estricted R efrigerant System T roubleshooting a restricted refrigerant system can be diffi cult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions.
Lock ed Rotor V oltage (L.R.V .) T est Locked rotor voltage (L.R.V .) is the actual voltage available at the compressor under a stalled condition. Single Phase Connections Disconnect power from unit.
Many compressor failures are caused by the following conditions: 1. Improper air fl ow over the evaporator . 2. Overcharged refrigerant system causing liquid to be returned to the compressor . 3. Restricted refrigerant system. 4. Lack of lubrication.
3. After all refrigerant has been recovered, disconnect suction and discharge lines from the compressor and remove compressor . Be certain to have both suction and discharge process tubes open to atmosphere. 4. Carefully pour a small amount of oil from the suction stub of the defective compressor into a clean container .
R OUTINE MAINTENANCE AIR FIL TER Clean the unit air intake fi lter at least every 300 to 350 hours of operation. Clean the fi lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.
