(A) Soft vinyl chloride pipe 22mm nominal pipe size.
(B) Hard vinyl chloride (PVC) coupling 22mm nominal pipe size.
(3) Connect the soft hard vinyl chloride pipe to the coupling, see fig.4
(4) The indoor unit uses gravity to drain; therefore the piping outside the unit should slope downward.

High-pressure switch, located on the discharge line, protects against high discharge pressure caused by such
as overcharge, condenser fan motor failure, system restriction, ect. it opens at a preset pressure rise. If
the system pressures go above the setting during abnormal conditions, the switch opens.
Service valve The service valves in the condensing unit come from the factory closed. This means the
refrigerant charge is isolated from the line side of the connection ports.
The service valves must be open (turned counter clockwise until seated) before the service port caps can be
removed and the hoses of the gauge manifold connected. in this position, the refrigerant has access from and
through the outdoor and indoor unit. The service valve can not be field repaired, there fore only a completed
valve or valve system and service caps are available for replacement Defrost control The control consists of a
defrost thermostat (and optional control board, depending on the type of remote control supplied). It Interrupts
the normal system heating operation to defrost the outdoor coil if the coil saturated suction temperature indicates
freezing temperatures
Defrost control simultaneously stops the outdoor and indoor fans and energizes the reversing valve solenoid to
return the system to the cooling cycle (outdoor unit as a condenser, indoor unit as evaporator). The defrost timer
(optional) limits defrosting. Normally the frost is removed and the defrost thermostat contacts open to terminate
defrosting before the maximum allowable time has elapsed. When defrosting is terminated, the outdoor and
indoor fan motors are energized, and the reversing valve solenoid is de-energized returning the unit to the
heating cycle.
Reversing valve in heat pumps, the change-over between heating and cooling modes is accomplished with a
valve that reverses the flow of refrigerant in the system. The reversing valve solenoid can be checked when the
power is off with an ohm-meter. Check for continuity and shorting to ground. With the control circuit (220-240V)
power on, check for the correct voltage at the solenoid coil. Check for a burned or overheated solenoid. With the
unit operating, other items can be checked, such as frost or condensate water on the refrigerant lines. Using a
remote measuring device. check the inlet and outlet line temperatures. Do not touch the line. If the reversing
valve is operating normally, the inlet and outlet temperatures on the appropriate lines should be close Any
difference would be due to heat loss or gain across the valve body. Temperatures are best checked with a
remote reading electronic-type thermometer with multiple probes. Figures 14 and 15 show test points (tp) on the
reversing valve for recording temperatures. insulate points for a more accurate reading. It the valve is defective;
shut-off all power to the unit and remove all charge from system. Remove the valve using a tubing cutter.
Wrap the new valve with a wet rag to prevent overheating while brazing.

Cleaning coils The coil should be washed-out with water, or blown-out with compressed air. Clean the coil
annually, or as required by the location or outdoor air conditions. Inspect the coil monthly and clean as required.
