4. Operate the vacuum pump to start evacuating. Perform
evacuating for about 15 minutes if the piping length is 20 meters.
(15 minutes for 20 meters) (assuming a pump capacity of 27 liters
per minute) Then confirm that the compound pressure gauge
reading is –101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold
valve.
6. Open fully the valve stem of the packed valves (both gas and
liquid sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
Packed valve handling precautions
•
Open the valve stem all the way out, but do not try to open it
beyond the stopper.
•
Securely tighten the valve stem cap with torque in the following
table:
Gas Leak Test

Wiring Connection
1. Remove the valve cover from the outdoor unit.
2. Connect the connecting cable to the terminals as identified with
their respective matched numbers on the terminal block of indoor
and outdoor unit.
3. When connecting the connecting cable to the outdoor unit
terminals, make a loop as shown in the installation diagram of
indoor and outdoor unit to prevent water coming in the outdoor unit.
4. Insulate the unused cords (conductors) from any water coming in
the outdoor unit. Proceed them so that they do not touch any
electrical or metal parts.

When two indoor units are installed in the separated rooms, it
is not necessary to change the selector switches.
Remote control selector switch
•
When two indoor units are installed in the same room or
adjacent two rooms, if operating a unit, two units may receive
the remote control signal simultaneously and operate. In this
case, the operation can be preserved by setting either one
indoor unit or remote control to B setting. (Both are set to A
setting in factory shipment.)
•
The remote control signal is not received when the settings of
indoor unit and remote control are different.
•
There is no relation between A setting/B setting and A room/B
room when connecting the piping and cables.
