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.
PRODUCT DESIGN The MBR/MBE blower cabinets with proper coil matches can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units are constructed with R-4.2 insulation. In areas of extreme humidity (greater than 80% consistently), insulate the exterior of the blower with insulation having a vapor barrier equivalent to ductwork insulation, providing local codes permit.
SYSTEM OPERATION COOLING HEATING 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 heating portion of the refrigeration cycle is similar to the cooling cycle. By energizing the reversing valve solenoid coil, the flow of the refrigerant is reversed.
SYSTEM OPERATION DEFROST CYCLE HEATING CYCLE The defrosting of the outdoor coil is jointly controlled by the defrost timing board, defrost (30/60) control, and compressor run time. The reversing valve on the heat pump models is energized in the cooling cycle through the "O" terminal on the room thermostat. Solid State Defrost Control These models have a 24 volt reversing valve coil.

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.

COPELAND COMPRESSOR 03 A 12345 L If voltage is registered at the coil, tap the valve body lightly while switching the system from HEATING to COOLING, etc. If this fails to cause the valve to switch positions, remove the coil connector cap and test the continuity of the reversing valve solenoid coil.
SERVICING S-40 AR*F & MBR ELECTRONIC BLOWERS TIME DELAY RELAY The MBR contains an Electronic Blower Time Delay Relay board, PCBFM103. This board provides on/off time delays for the blower motor in cooling and heat pump heating demands when “G” is energized. During a cooling or heat pump heating demand, 24Vac is supplied to terminal “G” of the EBTDR to turn on the blower motor. The EBTDR initiates a 7 second delay on and then energizes it’s onboard relay.
SERVICING 4.4 In order to make sure the blower is running when heat is on, the normally closed contacts on the EBTDR will power the blower motor if no G signal is received. 4.5 There may be delay on activation or deactivating heater elements. 5.0 Defrost Operation On heat pump units, when the room thermostat is set to the heating mode, the reversing valve is not energized.
SERVICING 24Vac from “W2” and the VSTB will remove the 24Vac from HR2. The contacts on HR2 will open between 30 to 70 seconds and heater elements #3 and #4 will be turned off and the blower motor will change to low speed. On most digital/electronic thermostats, “W2” will remain energized until the first stage demand “W1” is satisfied and then the “W1” and “W2” demands will be removed. 2.
SERVICING 5.0 Defrost Operation On heat pump units, when the room thermostat is set to the heating mode, the reversing valve is not energized. As long as the thermostat is set for heating, the reversing valve will be in the de-energized position for heating except during a defrost cycle. 5.1 The heat pump will be on and operating in the heating mode as described the Heating Operation in section 4. 5.

SERVICING S-111 FIXED ORIFICE RESTRICTOR DEVICES The fixed orifice restrictor device (flowrator) used in conjunction with the indoor coil is a predetermined bore (I.D.). It is designed to control the rate of liquid refrigerant flow into an evaporator coil. The amount of refrigerant that flows through the fixed orifice restrictor device is regulated by the pressure difference between the high and low sides of the system.
SERVICING Now determine if a burn out has actually occurred. Confirm by analyzing an oil sample using a Sporlan Acid Test Kit, AK3 or its equivalent. Remove the compressor and obtain an oil sample from the suction stub. If the oil is not acidic, either a burnout has not occurred or the burnout is so mild that a complete clean-up is not necessary. If acid level is unacceptable, the system must be cleaned by using the clean-up drier method. CAUTION Do not allow the sludge or oil to contact the skin.
SERVICING • The distance between the condenser and evaporator in a completely horizontal installation in which the indoor and outdoor unit do not differ more than 10 feet in vertical distance from each other can approach 150 feet, as long as the equivalent length does not exceed 150 feet. 4. Two-Stage Condensing Unit: The maximum length of tubing must not exceed 75 feet here indoor coil is located above the outdoor unit.
SERVICING 3. An oil trap is required at the evaporator only if the condenser is above the evaporator. Preformed oil traps are available at most HVAC supply houses, or oil traps may be created by brazing tubing elbows together (see diagram below). Remember to add the equivalent length from oil traps to the equivalent length calculation of the suction line.
SERVICING 3. Add the two readings together. 3. Consult proper table for quantity of air. TOTAL EXTERNAL STATIC NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired. 4. Consult proper table for quantity of air.
