removed during the first flush. After each system flush, allow the recovery machine to pull a vacuum on the system at the end of the procedure. 9. Close the valve on the inverted R22 cylinder and the gauge set valves. Pump the remaining refrigeraant out of the recovery machine and turn the machine off.

Open the valve on the R410A cylinder (vapor only). 3. Open the high pressure side of the manifold to allow R410A into the line set and indoor unit.
ST ART -UP 1. Rotate fan to check for frozen bearings or binding. 2. Inspect all factory and field-installed wiring for loose connections. 3. After evacuation is complete, open liquid line and suction line service valves to release refrigerant charge (contained in outdoor unit) into system.
506 468 -01 Issue 1 0 04 Pag e 13 Cooling Cycle Use gauge ports on suction line valve and liquid line valve for evacuating refrigerant lines and indoor coil.
5. Compare the subcooling value with those shown in T able 6. If subcooling is greater than shown, recover some refrigerant. If subcooling is less than shown, add some refrigerant. 506468-01 Page 14 T able 5 R410A T emperature/Pressure Chart Temp. E F Pressure Psig Temp.

5. Subtract the outdoor ambient temperature from the liquid line temperture to determine the approach temperature. 506468-01 Page 16 Check Charge Using Normal Operating Pressures Use T able 7 to perform maintenance checks. T able 7 is not a procedure for charging the system.
OPERA TION Outdoor unit and indoor blower cycle on demand from the room thermostat. When the thermostat blower switch is moved to the ON position, the indoor blower operates continuously . Filter Drier The unit is equipped with a large capacity bi-flow filter which keeps the system clean and dry .
DEFROST BOARD PRESSURE SWITCH CONNECTIONS The unit’s automatic reset pressure switches (LO PS - S87 and HI PS - S4) are factory-wired into the defrost board on the LO-PS and HI-PS terminals, respectively .
Defrost T emperature T ermination Shunt (Jumper) Pins —The defrost board selections are: 50, 70, 90, and 100°F (10, 21, 32 and 38°C). The shunt termination pin is factory set at 50°F (10°C). If the temperature shunt is not installed, the default termination temperature is 90°F (32°C).
