IMPORTANT INFORMATION SAFE REFRIGERANT HANDLING While these items will not cover every conceivable situation, they should serve as a useful guide. WARNING Refrigerants are heavier than air. They can "push out" the oxygen in your lungs or in any enclosed space.To avoid possible difficulty in breathing or death: • Never purge refrigerant into an enclosed room or space. By law, all refrigerants must be reclaimed. • If an indoor leak is suspected, thoroughly ventilate the area before beginning work.

PRODUCT DESIGN This section gives a basic description of cooling unit operation, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. CONDENSING UNIT These units are designed for free air discharge. Condensed air is pulled through the condenser coil by a direct drive propeller fan and then discharged from the cabinet top.
SYSTEM OPERATION COOLING The refrigerant used in the system is R-22. It is a clear, colorless, non-toxic, non-irritating, and non-explosive liquid. The chemical formula is CHCLF2. The boiling point, at atmospheric pressure is -41.4°F. The check valve at the indoor coil will open by the flow of refrigerant letting the now condensed liquid refrigerant bypass the indoor expansion device.

SYSTEM OPERATION EXPANSION VALVE/CHECK VALVE ASSEMBLY IN COOLING OPERATION EXPANSION VALVE/CHECK VALVE ASSEMBLY IN HEATING OPERATION Most expansion valves used in current Amana® Brand Heat Pump products use an internally checked expansion valve. This type of expansion valve does not require an external check valve as shown above. However, the principle of operation is the same.
SYSTEM OPERATION COOLING CYCLE - CONDENSING UNIT Indoor Coil Outdoor Coil Thermostatic Expansion Valve 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.
SYSTEM OPERATION AFE18-60A CONTROL BOARD DESCRIPTION The AFE18 control is designed for use in heat pump applications where the indoor coil is located above/downstream of a gas or fossil fuel furnace. It will operate with single and two stage heat pumps and single and two stage furnaces. The AFE18 control will turn the heat pump unit off when the furnace is turned on. An anti-short cycle feature is also incorporated which initiates a 3 minute timed off delay when the compressor goes off.

No reading - indicates open wiring, open fuse(s) no power or etc., from unit to fused disconnect service. Repair as needed. 4.
SERVICING 4. Check the continuity of the thermostat and wiring. Repair or replace as necessary. Resistance Heaters 1. Set room thermostat to a higher setting than room temperature so both stages call for heat. element helping the thermostat call for the next cooling cycle. This prevents the room temperature from rising too high before the system is restarted. A properly sized anticipator should maintain room temperature within 1 1/2 to 2 degree range. 2.
SERVICING S-4 CHECKING TRANSFORMER AND CONTROL CIRCUIT With power ON: WARNING Line Voltage now present. 1. Apply 24 VAC to terminals R1 and R2. 2. Should read 24 VAC at terminals Y1 and Y2. 3. Remove 24 VAC at terminals R1 and R2. 4. Should read 0 VAC at Y1 and Y2. A step-down transformer (208/240 volt primary to 24 volt secondary) is provided with each indoor unit. This allows ample capacity for use with resistance heaters. The outdoor sections do not contain a transformer.
SERVICING S-7 CHECKING CONTACTOR AND/OR RELAYS WARNING HIGH VOLTAGE! Disconnect ALL power before servicing or installing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. The compressor contactor and other relay holding coils are wired into the low or line voltage circuits.

SERVICING S-11 CHECKING LOSS OF CHARGE PROTECTOR (Heat Pump Models) The loss of charge protector senses the pressure in the liquid line and will open its contacts on a drop in pressure. The low pressure control will automatically reset itself with a rise in pressure. The low pressure control is designed to cut-out (open) at approximately 7 PSIG. It will automatically cut-in (close) at approximately 25 PSIG. Test for continuity using a VOM and if not as above, replace the control.
SERVICING relay holding coil is wired parallel with the start winding. As the motor starts and comes up to speed, the increase in voltage across the start winding will energize the start relay holding coil and open the contacts to the start capacitor. Two quick ways to test a capacitor are a resistance and a capacitance check. 2. Set an ohmmeter on its highest ohm scale and connect the leads to the capacitor A. Good Condition - indicator swings to zero and slowly returns to infinity.
SERVICING 6. Check for signal (24 volts) at the transformer. 7. Check for signal (24 volts) from the thermostat to the "G" terminal at the 16-pin connector. 1. Remove the motor leads from its respective connection points and capacitor (if applicable). 2. Check the continuity between each of the motor leads. 8. Using an ohmmeter, check for continuity from the #1 & #3 (common pins) to the transformer neutral or "C" thermostat terminal. If you do not have continuity, the motor may function erratically.

SERVICING S-17 CHECKING COMPRESSOR WARNING Hermetic compressor electrical terminal venting can be dangerous. When insulating material which supports a hermetic compressor or electrical terminal suddenly disintegrates due to physical abuse or as a result of an electrical short between the terminal and the compressor housing, the terminal may be expelled, venting the vapor and liquid contents of the compressor housing and system.
SERVICING WARNING Line Voltage now present. HI-POT A. If the compressor starts and continues to run, the cause for failure is somewhere else in the system. B. If the compressor fails to start - replace. COMPRESSOR GROUND TEST 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.
SERVICING If the valve fails to change its position, test the voltage (24V) at the valve coil terminals, while the system is on the COOLING cycle. If no voltage is registered at the coil terminals, check the operation of the thermostat an the continuity of the connecting wiring from the "O" terminal of the thermostat to the unit. If voltage is registered at the coil, tap the valve body lightly while switching the system from HEATING to COOLING, etc.
SERVICING AR*F & MBR WITH SINGLE STAGE HEAT PUMPS 3.0 Cooling Operation On heat pump units, when the room thermostat set to the cooling mode, 24Vac is supplied to “O” which energizes the reversing valve. As long as the thermostat is set for cooling, the reversing valve will be in the energized position for cooling. 3.1 On a demand for cooling, the room thermostat energizes “G” and “Y” and 24Vac is supplied to “Y” at the heat pump and the “G” terminal on the EBTDR board. 3.
SERVICING 5.5 When the temperature of the outdoor coil rises high enough to causes the defrost thermostat to open, the defrost cycle will be terminated. If at the end of the programmed 10 minute override time the defrost thermostat is still closed, the defrost board will automatically terminate the defrost cycle. 5.
SERVICING On heat pump units, when the room thermostat is set to the cooling mode, 24Vac is supplied to terminal “O” of the VSTB inside the MBE unit. The VSTB will supply 24Vac to “O” at the heat pump to energize the reversing valve. As long as the thermostat is set for cooling, the reversing valve will be in the energized position for cooling. 3.1 On a demand for cooling, the room thermostat energizes “G” and “Y” and 24Vac is supplied to terminals “G” and “Y/Y2” of the MBE unit.
SERVICING 5.4 When a defrost cycle is initiated, the contacts of the HVDR relay on the defrost board open and turns off the outdoor fan. The contacts of the LVDR relay on the defrost board closes and supplies 24Vac to “O” and “W2”. The reversing valve is energized and the contacts on HR1 close and turns on the electric heater(s). The unit will continue to run in this mode until the defrost cycle is completed. 5.
SERVICING S-61A CHECKING HEATER LIMIT CONTROL(S) Each individual heater element is protected with a limit control device connected in series with each element to prevent overheating of components in case of low airflow. This limit control will open its circuit at approximately 150°F. S-100 REFRIGERATION REPAIR PRACTICE DANGER Always remove the refrigerant charge in a proper manner before applying heat to the system. When repairing the refrigeration system: WARNING Disconnect ALL power before servicing.
SERVICING Pressure test the system using dry nitrogen and soapy water to locate leaks. If you wish to use a leak detector, charge the system to 10 psi using the appropriate refrigerant then use nitrogen to finish charging the system to working pressure, then apply the detector to suspect areas. If leaks are found, repair them. After repair, repeat the pressure test. If no leaks exist, proceed to system evacuation.
SERVICING S-103 CHARGING WARNING REFRIGERANT UNDER PRESSURE! * Do not overcharge system with refrigerant. * Do not operate unit in a vacuum or at negative pressure. Failure to follow proper procedures may cause property damage, personal injury or death. NOTE: This charging procedure can only be done in the cooling mode of operation. (Early production "a" models only.) All models with compressor process tube access valve can be processed in heating cycle if this valve is used.
SERVICING If the test shows: a. Below normal high side pressure. b. Above normal low side pressure. c. Low temperature difference across coil. d. Low amp draw at compressor. and the charge is correct. The compressor is faulty - replace the compressor. NOTE: THIS TEST CANNOT BE DONE IN THE HEATING MODE Verification of proper rotation of Scroll Compressors is made as follows. NOTE: The compressor may run backwards (noisy operation) for 1 or 2 seconds at shutdown.
SERVICING CHECKING SUPERHEAT Refrigerant gas is considered superheated when its temperature is higher than the saturation temperature corresponding to its pressure. The degree of superheat equals the degrees of temperature increase above the saturation temperature at existing pressure. See Temperature - Pressure Chart Table 7. 1. Attach an accurate thermometer or preferably a thermocouple type temperature tester to the suction line at a point at least 6" from the compressor. 2.
SERVICING S-109 CHECKING SUBCOOLING Refrigerant liquid is considered subcooled when its temperature is lower than the saturation temperature corresponding to its pressure. The degree of subcooling equals the degrees of temperature decrease below the saturation temperature at the existing pressure. 1. Attach an accurate thermometer or preferably a thermocouple type temperature tester to the liquid line as it leaves the condensing unit. 2.
SERVICING S-113 OVERCHARGE OF REFRIGERANT An overcharge of refrigerant is normally indicated by an excessively high head pressure. An evaporator coil, using an expansion valve metering device, will basically modulate and control a flooded evaporator and prevent liquid return to the compressor. An evaporator coil, using a capillary tube metering device, could allow refrigerant to return to the compressor under extreme overcharge conditions.
SERVICING S-120 REFRIGERANT PIPING The piping of a refrigeration system is very important in relation to system capacity, proper oil return to compressor, pumping rate of compressor and cooling performance of the evaporator. This long line set application guideline applies to all ARI listed R22 air conditioner and heat pump split system matches of nominal capacity 18,000 to 60,000 Btuh.
