Outdoor unit wiring connection
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 outdoor units.
5. Insulate unused cords (conductors)
with PVC-tape. Process them so they
do not touch any electrical or metal
parts.

Air purging and test operation
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.
Air purging
The indoor unit and tubing between
the indoor and outdoor unit must be
leak tested and evacuated to remove
any noncondensables 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.
When the connecting pipe length is
longer than 5m, additional refrigerant
should be added into the unit
accordingly to the table below:
