12 A good underst anding 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) i[...]

14 The overload is wired in series with the common motor terminal. The overload senses both major amperage and compressor temperature. High motor temperature or amperage heats the disc causing it to open and break the circuit to the common motor terminal. COMPONENTS: OPERA TION & TESTING W ARNING DISCONNECT ELECTRICAL POWER TO UNIT BEFORE SER V[...]

15 1. With no power to unit, remove the leads from the com- pressor terminals. 2. Using an ohmmeter , test continuity between terminals C-S and C-R. If no continuity , the compressor overload is open and the compressor must be replaced. F AN MOTOR A single phase permanent split cap acitor motor is used to drive the evaporator blower and condenser f[...]

16 MONEYSA VER ® SWITCH (Rocker Switch- See Figure 8) This rocker switch can be depressed to either YES or NO . In the YES position you will get the most economical operation. Both the fan and the compressor will cycle on and of f together , maintaining the selected temperature at a more const ant level and reducing the humidity more efficiently .[...]

17 SYSTEM CONTROL P ANEL ("KQ" Models Only- See Figure 1 0) The KQ Model unit uses a five position control switch to regu- late the operation of the unit. Function of each position (clock- wise rotation) is as follows: SYSTEM CONTROL SWITCH - TEST (See Figure 1 1 ) T urn knob to phase of switch to be tested. There must be continuity as fo[...]

20 SYSTEM CONTROL P ANEL (See Figure 24) A six-position control switch is used to regulate the operation of the fan motor and compressor . The compressor can be operated with the fan operating at low , medium or high speed. The fan motor can also be operated independently on medium speed. See switch section as indicated on decorative control panel.[...]

21 SYSTEM CONTROL SWITCH (See Figure 26) (Heat Pump & Electric Heat Models) An eight position control switch is used to regulate the operation of the fan motor and compressor . The compressor can be operated with the fan operating at low , medium or high speed in the cooling or heating mode. The fan motor can also be operated independently on m[...]

24 THERMOST A T - Models ES, YS, EM, YM, EL, YL (See Figure 32) A cross ambient thermost at is used on all heat pump and electric heat units. In addition to cycling the unit in a heating or cooling operation, the thermostat will terminate the cooling cycle in the event ice forms on the evaporator coil, in this case the thermostat functions as a de-[...]

25 DEFROST THERMOST A T (Heat Pump Models Only) (See Figure 35) This thermostat is single pole - double throw with contact s between terminals "2" and "3" closing on temperature rise and contact s between terminals "2" and "1" closing on temperature fall. When the contact s between terminals "2" and[...]

26 CAP ACITOR, RUN (See Figure 38) A run capacitor is wired across the auxiliary and main winding of a single phase permanent split capacitor motor such as the compressor and fan motor . A single capacitor can be used for each motor or a dual rated capacitor can be used for both. The capacitor's primary function is to reduce the line current w[...]

27 CHECK V AL VE (See Figure 39) A unique two-way check valve is used on the reverse cycle heat pumps. It is pressure operated and used to direct the flow of refrigerant through a single filter drier and to the proper capillary tube during either the heating or cooling cycle NOTE: The slide (check) inside the valve is made of teflon. Should it beco[...]

28 TESTING REVERSING V AL VE 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. Check the operation of the valve by starting the syst[...]

29 HEA TING ELEMENT (See Figure 44) All heat pumps and electric heat models are equipped with a heating element with the exception of the YS09J10. The "YS", "ES" and "EK12" models are equipped with a 3.3 KW element. The "YM", "EM" and "EK18" models are equipped with a 4.0 KW element. The &[...]

30 HERMETIC COMPONENT REPLACEMENT The following procedure applies when replacing components in the sealed refrigeration circuit or repairing refrigerant leaks. (Compressor , condenser , evaporator , capillary tube, refrigerant leaks, etc.) 1. Recover the refrigerant from the system at the process tube located on the high side of the system by insta[...]

31 NOTE: In order to access the sealed system it will be necessary to install Schrader type fittings to the process tubes on the discharge and suction of the compressor . Proper recovery refrigerant procedures need to be adhered to as outlined in EP A Regulations. THIS SHOULD ONL Y BE A TTEMPTED BY QUALIFIED SER VICE PERSONNEL. An undercharged syst[...]

32 Overcharged Refrigerant Systems Compressor amps will be near normal or higher . Noncondensables can also cause these symptoms. T o confirm, remove some of the charge, if conditions improve, system may be overcharged. If conditions don’t improve, Noncondensables are indicated. Whenever an overcharged system is indicated, always make sure that t[...]

33 A quick check for either condition begins at the evaporator . With a partial restriction, there may be gurgling sounds at the metering device entrance to the evaporator . The evaporator in a partial restriction could be p artially frosted or have an ice ball close to the entrance of the metering device. Frost may continue on the suction line bac[...]

34 Routine Maintenance 1. Clean the unit air intake filter at least every 250 to 300 fan hours of operation or when the unit's indicator light is on if so equipped. Clean the filters with a mild detergent in warm water and allow to dry thoroughly before reinstalling. 2. The indoor coil (evaporator coil), the outdoor coil (condenser coil) and b[...]
