1. Highlights of electrical wiring installation
•
All field wiring construction should be finished by
qualified electrician.
•
Air conditioning equipment should be grounded ac-
cording to the local electrical regulations.
•
Current leakage protection switch should be in-
stalled.
•
Do not connect the power wire to the terminal of
signal wire.
•
When power wire is parallel with signal wire, put
wires to their own wire tube and remain at least
300mm gap.
•
According to table in indoor part named “the speci-
fication of the power” to choose the wiring, make
sure the selected wiring not small than the date
showing in the table.
•
Select different colors for different wire according to
relevant regulations.
•
Do not use metal wire tube at the place with acid or
alkali corrosion, adopt plastic wire tube to replace it.
•
There must be not wire connect joint in the wire
tube If joint is a must, set a connection box at the
place.
•
The wiring with different voltage should not be in
one wire tube.
•
Ensure that the color of the wires of outdoor and
the terminal No. are same as those of indoor unit
respectively.

11. Test Operation
1. The test operation must be carried
out after the entire installation has been
completed.
2. Please confirm the following points
before the test operation.
•
The indoor unit and outdoor unit are installed prop-
erly.
•
Piping and wiring are properly connected.
•
Ensure that there are no obstacles near the inlet and
outlet of the unit that might cause poor perfor-
mance or product malfunction.
•
The refrigeration system does not leak.
•
The drainage system is unimpeded and draining to a
safe location.
•
The heating insulation is properly installed.
•
The grounding wires are properly connected
•
The length of the piping and the added refrigerant
stow capacity have been recorded.
•
The power voltage is the correct voltage for the air
conditioner.
CAUTION: Failure to perform the test run may result in unit
damage, property damage or personal injury.
3. Test Run Instructions
1. Open both the liquid and gas stop valves.
2. Turn on the main power switch and allow the unit to
warm up.
3. Set the air conditioner to COOL mode, and check the
following points.
Indoor unit
•
Whether the switch on the remote controller works
well.
•
Whether the buttons on the remote controller
works well.
•
Whether the air flow louver moves normally.
•
Whether the room temperature is adjusted well.
•
Whether the indicator lights normally.
•
Whether the temporary buttons works well.
•
Whether the drainage is normal.
•
Whether there is vibration or abnormal noise during
operation.
Outdoor unit
•
Whether there is vibration or abnormal noise during
operation.
•
Whether the generated wind, noise, or condensed
of by the air conditioner have influenced your neigh-
borhood.
•
Whether any of the refrigerant is leaked.
