Installing Outdoor Unit
①
Installing Outdoor Unit
1. Selection of Installation Position of Outdoor Unit
z
A place where noise and airflow generated by air exhaust do not affect the neighbors;
z
Choose a place with good ventilation to ensure good ventilation of outdoor unit;
z
No obstacles near the outdoor unit obstructing the air intake and air exhaust of the unit;
z
The installation position shall be able to withstand the weight and vibration of the outdoor unit and ensure safe
installation;
z
A place without the leakage of any flammable gases or corrosive gases;
z
Do not allow strong airflow to blow the air outlet of the outdoor unit; if so, the fan may suffer from insufficient airflow
thus failure may occur.
z
Do not install the unit in a place where there is machine oil, sulphur gas or high noise.
Attention : Enough space must be left above the outdoor unit to allow the unit to produce the best effect.
2. Installing Outdoor Unit
z
If the outdoor unit is installed on steady floor such as concrete, use M10 screws and nuts to secure the unit and
ensure the unit is installed vertically and horizontally (refer to the figure for the positions of bolt holes).
z
Do not install the unit on the roof of a building.
z
In the event of noise owing to vibration, insert rubber cushion between the outdoor unit and the installation base.
z
When the unit is under heating or defrosting operation, the outdoor shall carry out draining operation.
z
If drainage pipe is to be installed, insert the drainage joint (13) (accessory 1) into the drainage hole in the chassis of
the outdoor unit and then connect a drainage pipe to the drainage joint (if a drainage joint is to be used, the
installation height of the outdoor unit must be at least 5cm).

Air Exhaust
1. Remove the nut cover at the shutoff valve.
2. Align with the center of the fitting pipe and manually tighten the conical nut sufficiently.
3. Use spanner to tighten the conical nut.
4. Remove the one way valve caps at the liquid valve and the gas valve.
5. Use inner hexagon spanner to twist off the liquid valve body and at the same time use screwdriver to open the valve
core of the one way valve. Now gas shall flow out.
6. After gas continues flowing out for about 15 second and refrigerant gas begins to flow out, close the one way valve
and tighten the valve cap.
7. Completely open the valve body of the liquid valve and the gas valve (Figure 9).
8. Turn and tighten the valve cap, then use soap water or a leak detector to check if there is gas leakage at the outdoor
and indoor units and the pipeline connections.
9.
If conditions permit, use a vacuum pump to exhaust air in the unit from the one way valve (Figure 10).
