AIR pURGING AND TEST OpERATION
1 Remove the electrical control board cover from the outdoor unit by loosening the screw
2 Connect the connective cables to the terminals as identified with their respective matched numbers on the terminal block of
indoor and outdoor units
3 Secure the cable onto the control board with the cord clamp
4 To prevent the ingress of water, form a loop of the connective cable as illustrated in the installation diagram of indoor and out-
door units
5 Insulate unused cords (conductors) with PVC-tape Process them so they do not touch any electrical or metal parts
NOTE:
Connective pipe length will affect the capacity and energy efficiency of the unit. The nominal efficiency is tested basing on the
pipe length of 5 meters.
1. Air purging
The indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any noncon-
densables and moisture from the system
Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have been properly connected
and all wiring for the test run has been completed
Pipe length and refrigerant amount:
For the R410A refrigerant model, make sure the refrigerant added into air conditioner is liquid form in any cases
When relocating the unit to another place, using vacuum pump to perform evacuation
CAUTION
Open the valve stem until it hits against the stopper Do not try to open it further
Securely tighten the valve stem cap with a spanner or the like
