10. Engineering of Electrical Wiring
10.1 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.
•
You must first choose the right cable size before
preparing it for connection. Be sure to use H07RN-F
cables.

11. Test Operation
11.1 The test operation must be carried out
after the entire installation has been
completed.
11.2 Please confirm the following points
before the test operation.
•
The indoor unit and outdoor unit are installed prop-
erly.
•
Tubing and wiring are correctly completed.
•
The refrigerant pipe system is leakage-checked.
•
The drainage is unimpeded.
•
The ground wiring is connected correctly.
•
The length of the tubing and the added stow capac-
ity of the refrigerant have been recorded.
•
The power voltage fits the rated voltage of the air
conditioner.
•
There is no obstacle at the outlet and inlet of the
outdoor and indoor units.
•
The gas-side and liquid-side stop values are both
opened.
•
The air conditioner is pre-heated by turning on the
power.
11.3 Test operation
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.
