Precautions

WARNING

Maintenance must be performed by qualified
professionals. Otherwise, it may cause personal injury

or damage.
Do not repair air conditioner by yourself. It may cause

electric shock or damage. Please contact dealer when
you need to repair air conditioner.

Do not extend fingers or objects into air inlet or air
outlet. It may cause personal injury or damage.

Precautions

WARNING

For the air conditioner with plug, the plug should be reachable after
finishing installation.

For the air conditioner without plug, an circuit break must be
installed in the line.

If you need to relocate the air conditioner to another place, only the
qualified person can perform the work. Otherwise, it may cause
personal injury or damage.
Select a location which is out of reach for children and far away from
animals or plants.If it is unavoidable, please add the fence for safety
purpose.

Installation of outdoor unit

Step six: neaten the pipes

1. The pipes should be placed along the wall,
bent reasonably and hidden possibly. Min.
semidiameter of bending the pipe is 4in(10cm).

2. If the outdoor unit is higher than the wall

hole, you must set a U-shaped curve in the

pipe before pipe goes into the room, in

order to prevent rain from getting into the

room.

Note:

● The through-wal height of drain hose
shouldn't be higher than the outlet
pipe hole of indoor unit.

● The water outlet can't be placed
in water in order to drain smoothly.

● Slant the drain hose slightly dow-

nwards. The drain hose can't be

Vacuum pumping

Use vacuum pump

1. Remove the valve caps on
the liquid valve and gas
valve and the nut of refri­ gerant charging vent.

2. Connect the charging hose

of piezometer to the refri-

gerant charging vent of gas
valve and then connect the
other charging hose to the
vacuum pump.

3. Open the piezometer com-

pletely and operate for
10-15min to check if the

pressure of piezometer re-

mains in -0.1MPa.

4. Close the vacuum pump
and maintain this status for
1-2min to check if the pres-

sure of piezometer remains
in -0.1MPa. If the pressure decreases, there may be leakage.

5. Remove the piezometer, open the valve core of liquid valve and gas valve
completely with inner hexagon spanner.

6. Tighten the screw caps of valves and refrigerant charging vent.

7. Reinstall the handle.

Leakage detection

1. With leakage detector:
Check if there is leakage with leakage detector.

2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more
than 3min. If there are air bubbles coming out of this position, there's a leakage.

Check after installation

● Check according to the following requirement after nishing installation.

Items to be checked Possible malfunction

Has the unit been installed rmly? The unit may drop, shake or emit noise.
Have you done the refrigerant leakage

test?

Is heat insulation of pipeline sufcient?

Is water drained well?

It may cause insufcient cooling

(heating) capacity.
It may cause condensation and water

dripping.
It may cause condensation and water

dripping.

Is the voltage of power supply accord­ing to the voltage marked on the
nameplate?

Is electric wiring and pipeline installed
correctly?

Is the unit grounded securely? It may cause electric leakage.
Does the power cord follow the speci-

cation?

Is there any obstruction in the air inlet
and outlet?

The dust and sundries caused during
installation are removed?

The gas valve and liquid valve of
connection pipe are open completely?

It may cause malfunction or damaging
the parts.

Test operation

1. Preparation of test operation

● The client approves the air conditioner.

● Specify the important notes for air conditioner to the client.

2. Method of test operation

● Put through the power, press ON/OFF button on the remote controller to start

operation.

● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check

whether the operation is normal or not.

● If the ambient temperature is lower than 61°F(16°C), the air conditioner can’t
start cooling.

Conguration of connection pipe

1. Standard length of connection pipe

● 16,5ft (5m), 25ft (7.5m), 26,5ft (8m).

2. Min. length of connection pipe is 9,8ft (3m).

3. Max. length of connection pipe and max. high difference.

4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe

● After the length of connection pipe is prolonged for 33,3ft (10m) at the basis of

standard length, you should add 5ml of refrigerant oil for each additional

16,5ft (5m) of connection pipe.

● The calculation method of additional refrigerant charging amount (on the basis

of liquid pipe):
Additional refrigerant charging amount = prolonged length of liquid pipe ×
additional refrigerant charging amount per meter

● When the length of connection pipe is above 16,5ft (5m), add refrigerant

according to the prolonged length of liquid pipe. The additional refrigerant

charging amount per meter is different according to the diameter of liquid
pipe. See the following sheet.
