Determine that capacitor is serviceable. 2.
COMPONENTS TESTING (Continued) HEATING ELEMENT (See Figure 25) All heat pumps and electric heat models are equipped with a heating element with the exception of models starting with YS09. The “YS” and “ES” models are equipped with a 3.3 KW element. The “YM” and “EM” models are equipped with a 4.0 KW element. The “YL” and “EL” models are equipped with a 5.2 KW element. The EQ08 has a 1.15 KW element.
ELECTRONIC CONTROL SEQUENCE OF OPERATION QME PROGRAMMABLE AND XQ MODELS Mode Control The mode control pad(s) allow the selection of the operating modes of the unit. There is a two second delay before the mode activates its appropriate relay. OPERATING SEQUENCE / CHARACTERISTICS AND FEATURES Compressor Operation The run state of the compressor is determined by the difference between the indoor ambient temperature and the set temperature. See specific mode of operation for details.
REFRIGERATION SEQUENCE OF OPERATION A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more difficult and time consuming, if not (in some cases) entirely impossible. The refrigeration system uses four basic principles (laws) in its operation they are as follows: 1. “Heat always flows from a warmer body to a cooler body.” 2.
SEALED REFRIGERATION SYSTEM REPAIRS IMPORTANT ANY SEALED SYSTEM REPAIRS TO COOL-ONLY MODELS REQUIRE THE INSTALLATION OF A LIQUID LINE DRIER. ALSO, ANY SEALED SYSTEM REPAIRS TO HEAT PUMP MODELS REQUIRE THE INSTALLATION OF A SUCTION LINE DRIER. EQUIPMENT REQUIRED: 1. Voltmeter 9. 2. Ammeter 10. Low Pressure Gauge - (30 - 150 lbs.) 3. Ohmmeter 11. Vacuum Gauge - (0 - 1000 microns) 4. E.P.A. Approved Refrigerant Recovery System EQUIPMENT MUST BE CAPABLE OF: 5.
Method Of Charging / Repairs The acceptable method for charging the RAC system is the Weighed in Charge Method. The weighed in charge method is applicable to all units. It is the preferred method to use, as it is the most accurate. The weighed in method should always be used whenever a charge is removed from a unit such as for a leak repair, compressor replacement, or when there is no refrigerant charge left in the unit. To charge by this method, requires the following steps: 1.
WARNING WARNING ELECTRIC SHOCK HAZARD Turn off electric power before service or installation. HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Extreme care must be used, if it becomes necessary to work on equipment with power applied. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants. Failure to do so could result in serious injury or death.
Restricted Refrigerant System Troubleshooting a restricted refrigerant system can be difficult. 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. A partial restriction allows some of the refrigerant to circulate through the system. With a complete restriction there is no circulation of refrigerant in the system.
HERMETIC COMPONENTS CHECK WARNING WARNING BURN HAZARD Proper safety procedures must be followed, and proper protective clothing must be worn when working with a torch. CUT/SEVER HAZARD Be careful with the sharp edges and corners. Wear protective clothing and gloves, etc. Failure to follow these procedures could result in moderate or serious injury. Failure to do so could result in serious injury. METERING DEVICE Capillary Tube Systems All units are equipped with capillary tube metering devices. 3.
REVERSING VALVE DESCRIPTION/OPERATION WARNING ELECTRIC SHOCK HAZARD Disconnect power to the unit before servicing. Failure to follow this warning could result in serious injury or death. The Reversing Valve controls the direction of refrigerant flow to the indoor and outdoor coils. It consists of a pressure-operated, main valve and a pilot valve actuated by a solenoid plunger. The solenoid is energized during the heating cycle only. The reversing valves used in the RAC system is a 2-position, 4-way valve.
TESTING THE COIL WARNING ELECTRIC SHOCK HAZARD Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. The solenoid coil is an electromagnetic type coil mounted on the reversing valve and is energized during the operation of the compressor in the heating cycle. 1. Turn off high voltage electrical power to unit. 2. Unplug line voltage lead from reversing valve coil. 3.
Touch Test in Heating/Cooling Cycle WARNING BURN HAZARD Certain unit components operate at temperatures hot enough to cause burns. 6. Protect new valve body from heat while brazing with plastic heat sink (Thermo Trap) or wrap valve body with wet rag. 7. Fit all lines into new valve and braze lines into new valve. Proper safety procedures must be followed, and proper protective clothing must be worn. WARNING EXPLOSION HAZARD The use of nitrogen requires a pressure regulator.
COMPRESSOR CHECKS WARNING ELECTRIC SHOCK HAZARD Turn off electric power before service or installation. Extreme care must be used, if it becomes necessary to work on equipment with power applied. Failure to do so could result in serious injury or death. Locked Rotor Voltage (L.R.V.) Test 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.
Single Phase Resistance Test WARNING 1. Improper air flow over the evaporator. 2. Overcharged refrigerant system causing liquid to be returned to the compressor. 3. Restricted refrigerant system. 4. Lack of lubrication. Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). 5. Liquid refrigerant returning to compressor causing oil to be washed out of bearings. Touch the leads of the ohmmeter from terminals common to start (“C” to “S”).
COMPRESSOR REPLACEMENT Recommended procedure for compressor replacement WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing. WARNING 3.
SPECIAL PROCEDURE IN THE CASE OF MOTOR COMPRESSOR BURNOUT WARNING ELECTRIC SHOCK HAZARD Turn off electric power before service or installation. Failure to do so may result in personal injury, or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure. Proper safety procedures must be followed, and proper protective clothing must be worn when working with refrigerants. Failure to follow these procedures could result in serious injury or death.
ROUTINE MAINTENANCE WARNING ELECTRIC SHOCK HAZARD Turn off electric power before inspections, maintenances, or service. Extreme care must be used, if it becomes necessary to work on equipment with power applied. NOTICE Units are to be inspected and serviced by qualified service personnel only. Use proper protection on surrounding property. Failure to follow this notice could result in moderate or serious property damage. Failure to do so could result in serious injury or death.
