PRODUCT DESIGN 25 This section gives a basic description of cooling unit opera- tion, 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.
PRODUCT DESIGN 26 The ASX [16 & 18], ASZ [16 & 18], DSX16 and DSZ16 series split system units use a two-stage scroll compressor. The two-step modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll.
PRODUCT DESIGN 27 CAPACITY CONTROL During the compression process, there are several pockets within the scroll that are compressing gas. Modulation is achieved by venting a portion of the gas in the first suction pocket back to the low side of the compressor thereby reducing the effective displacement of the compressor.
SYSTEM OPERA TION 28 COOLING The refrigerant used in the system is R-410A. It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125.
SYSTEM OPERA TION 29 DEFROST CYCLE The defrosting of the outdoor coil is jointly controlled by the defrost control board and the defrost thermostat. Solid State Defrost Control During operation the power to the circuit board is controlled by a temperature sensor, which is clamped to a feeder tube entering the outdoor coil.

SYSTEM OPERA TION 31 RESTRICTOR ORIFICE ASSEMBLY IN COOLING OPERATION RESTRICTOR ORIFICE ASSEMBLY IN HEATING OPERATION 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 OPERA TION 32 AFE18-60A CONTROL BOARD DESCRIPTION The AFE18 control is designed for use in heat pump applica- tions 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.

Using a voltmeter, measure the voltage across terminals L1 and L2 of the contactor for the condensing unit or at the field connections for the air handler or heaters.
SERVICING 36 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. 2. With voltmeter, check for 24 volts at each heater relay.

SERVICING 41 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.
SERVICING 42 The discharge check valve closes off high side pressure to the compressor after shut down allowing equalization through the scroll flanks. Equalization requires only about ½ second. To prevent the compressor from short cycling, a Time Delay Relay (Cycle Protector) has been added to the low voltage circuit.
SERVICING 43 S-16A CHECKING FAN AND BLOWER MOTOR WINDINGS (PSC MOTORS) The auto reset fan motor overload is designed to protect the motor against high temperature and high amperage condi- tions by breaking the common circuit within the motor, similar to the compressor internal overload.

SERVICING 50 Do not use a low voltage output instrument such as a volt- ohmmeter. HI-POT COMPRESSOR GROUND TEST 3. If a ground is indicated, then carefully remove the com- pressor terminal protective cover and inspect for loose leads or insulation breaks in the lead wires.
SERVICING 51 3. Connect good capacitors of the right MFD and voltage rating into the circuit as shown. 4. With power ON, close the switch. WA RN I NG Li ne Volt ag e now pres ent. A . If the compressor starts and continues to run, the cause for failure is somewhere else in the system.
SERVICING 52 3. Check the temperature at which the control opens its contacts by raising the temperature of the control. Part # 0130M00009P which is used on 2 and 2.5 ton units should open at 60°F ± 5°F. Part # 0130M00001P which is used on 3 thru 5 ton units should open at 75°F ± 6°F.
SERVICING 53 1.4 The compressor and condenser fan are turned off and after a 65 second delay off, the relay on the EBTDR board is de-energized and the blower is turned off. 2.0 Heating Operation 2.1 On a demand for heat, the room thermostat energizes “W1” and 24Vac is supplied to heat sequencer, HR1, on the heater assembly.
SERVICING 54 4.5 When the first stage heat demand “Y” is satisfied, the room thermostat will remove the 24Vac from “G” and “Y”. The heat pump is turned off and the blower motor turns off after a 65 second off delay.
SERVICING 55 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.
SERVICING 56 5.0 DEFROST OPERA TION 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.
SERVICING 57 For the 3 rd and 4 th heater elements to operate on a second stage heat demand, the PJ4 jumper on the VSTB inside the MBE/AEPF must be cut. With the PJ4 jumper cut, the VSTB will run the blower motor on low speed on a “W1” only demand.
SERVICING 58 The outdoor fan will change to high speed operation. If the “Y2” demand is present and becomes satisfied, the thermostat will remove the “Y2” demand and the VSTB will remove the 24Vac from “Y/Y2” at the heat pump. The blower will drop to 60% of the programmed cfm and the outdoor fan will change to low speed.
SERVICING 59 Alternately, the system CFM can be determined by operating the electric heaters and indoor blower WITHOUT having the compressor in operation. Measure the temperature rise as close to the blower inlet and outlet as possible. If other than a 240V power supply is used, refer to the BTUH CAPACITY CORRECTION FACTOR chart below.
SERVICING 60 2. Using an ohmmeter, test across the fuse link for continu- ity - no reading indicates the link is open. Replace as necessary. NOTE: The link is designed to open at approximately 333°F. DO NOT WIRE AROUND - determine reason for failure.
SERVICING 61 IMPORTANT NOTE: Because of the potential damage to compressors, do not allow suction pressure at service valve to drop below 20 PSIG when pumping unit system down for repair. Outdoor section, depending on line set length and amount of charge in system, may not be able to hold the entire system charge.

SERVICING 66 S-106 OVERFEEDING Overfeeding by the expansion valve results in high suction pressure, cold suction line, and possible liquid slugging of the compressor. If these symptoms are observed: 1. Check for an overcharged unit by referring to the cooling performance charts in the servicing section.
SERVICING 67 4. Review the technical information manual or specification sheet for the model being serviced to obtain the design subcooling. 5. Compare the hi-pressure reading to the "Required Liquid Line Temperature" chart (page 43). Find the hi-pressure value on the left column.
SERVICING 68 2. Remove the orifice or tube strainer assembly and re- place. 3. Replace liquid line drier, evacuate and recharge. CHECKING EQUALIZATION TIME During the "OFF" cycle, the high side pressure bleeds to the low side through the fixed orifice restriction device.
SERVICING 69 NOTE: At least twelve (12) inches of the suction line immediately out of the compressor stub must be discarded due to burned residue and contaminates. 1. Remove compressor discharge line strainer. 2. Remove the liquid line drier and expansion valve.
SERVICING 70 4. Two-Stage Condensing Unit: The maximum length of tubing must not exceed 80 feet where indoor coil is located above the outdoor unit. NOTE: When the outdoor unit is located above the indoor coil, the maximum vertical rise must not exceed 25 feet.
