The following safety precautions must be taken when using your air
conditioner.
SAFETY PRECAUTIONS
1. Warning: Prior to repair, disconnect thepower cord.
2. Use properparts: use onlyexact replacement parts.(Also, we recommend replacing parts rather
than repairing them.)
3. Use theproper tools: use the proper toolsand test equipment, and know howto use them. Using
defective tools ortest equipment may cause problems later-intermittentcontact, for example.
4. Power cord:prior to repair, check the power cord andreplace it if necessary.
5. Avoid using anextension cord, and avoid tapping intoa power cord. This practice may result in
malfunction or fire.
6. Aftercompleting repairs and reassembly, check the insulation resistance.
Procedure: prior toapplying power, measure the resistancebetween the power cord and theground
terminal. The resistance must be greater than 30megohms.
7. Make surethat the grounds are adequate.
8. Make surethat the installation conditions are satisfactory. Relocate the unit if necessary.
9. Keep childrenaway from the unit while itis being repaired.
10. Be sureto clean the unit and itssurrounding area.

Location of indoor unit
A place solid enough to bear the weight of the unit and not cause any shake.
Good ventilation, less dust, far from direct rain and sunshine.
Avoid places close to inflammable gas leakage.
Keep the air inlet and outlet at a far distance from the blockage.
Keep the height distance between the indoor and outdoor unit at most 5m.
Mount on the wall solid enough to bear the weight of the unit and not cause any shake.
Avoid direct sunshine.
A place easy for condensate drain and easy for connecting with the outdoor unit.
Keep a far distance away from the fluorescent lamp, it may influence the operation of remote controller.
Location of outdoor unit
Keep at least 1m away from the TV radio and other home appliances.
A place where the air discharged out of the outdoor unit or the operation noise will not annoy your
neighbours.
No blockage near the outdoor unit.
Avoid places close to inflammable gas leakage.
Selecting area for installation
INSTALLATION
Select an area for installation that is suitable to the customer’s needs.
It is harmful to the air conditioner if it is used in the following environments: greasy areas (including area
near machines). Salty area such as coastal areas, areas where sulfuric gas is present such as hot spring
areas. Contact your dealer for advice.

the wall and the pipeline, or wrap
up the pipeline with 7-8 layers of
insulating plastic tape.

INSTALLATION
The drain hose must be arranged beneath the copper pipe.
The drain hose must not be hunched or twisted.
While wrapping up the drain hose, do not pull it.
The drain hose through the room must be wrapped up by the
thermal insulation materials.
The copper pipe and the drain hose must be wrapped up by felt
strip. Adiabatic pad should be used at where the pipe contacts
the wall.

ROUTE OF PIPE
If pipe comes out of the right side of the indoor unit, cut part
1 of the unit;
If pipe comes out of the lower-right side of the indoor unit, cut
part 2 of the unit;
If pipe comes out of the left side of the indoor unit, cut part 3
of the unit.

If pipe comes out of the left side of the indoor unit, the drain hose
must be refitted, otherwise water leakage may occur.
Refit methods: Interchange the position of drain hose and drain
rubber plug.
Clearance is not allowed after refit, it would lead to water leakage.

Do not exhaust the inside air just by loosing the nut since there is the air of certain pressure
inside the tube of indoor unit. Please do not make extra effort for fear of damaging the flare.
Attention:
Please break the evaporator craft tube with pincers before connecting. After exhausting the inside air,
use the wrench to twist down the nut of connecting tube of the evaporator.

Special cable must be used to connect indoor unit and outdoor unit. It should be ensured
that the terminals are not influenced by external force. Poor connection may cause fire.
The electric box cover must be mounted and secured in position, otherwise fire or electrical
shock may occur because of dust or moisture.
The connecting cables must be clipped together.
Please take the electric circuit diagram attached to the indoor/outdoor units as major
reference while installing.
The power wire and signal wire between the indoor/outdoor units must be connected
one by one as per corresponding number on the wiring terminal board.
All the models shall be connected with the mains which has system impedance limitations.
While installing the unit, please see the following table for impedance information or
