!
CAUTION
Be sure that the drain
hose is not loosely
connected or bent.
Bending
Upwards
You are free to choose the side (left or right) for the installation of drain hose. Please ensure the
!
smooth flow of condensed water of the indoor unit during installation. (Carelessness may result in water
CAUTION
leakage.)
Please mount the Outdoor unit on stable ground to prevent vibration and increase of noise level.
G
Decide the location for piping after sorting out the different types of pipe available.
G
Please Remove The Cover For Wire Connection
Procedure to remove the cover of wiring terminals
Remove the screw (1 piece).
G
Hold the projected part at the lower left of the cover and push the cover
G
upwards to remove it.
To close the cover, insert the upper part of the cover into the body of outdoor
G
unit, then be sure that the hook below the cover is plugged in before screwing.

Removal Of Air From The Pipe And Gas Leakage
Procedures of using Vacuum Pump for Air Removal
As shown in figure on the right, remove
the cap of valve head and valve core
1
and then connect them to the vacuum
pump and sub-division valve.
Fully tighten the "Hi" shuttle of the sub-
division valve and completely unscrew
the "Lo" shuttle. Run the vacuum pump
2
for about 10–15 minutes, then completely
tighten the "Lo" shuttle and switch off
the vacuum pump.
Completely unscrew the spindle of the
service valve (at 2 places) in anti-
3
clockwise direction to allow the flow of
coolant (using Allen key).
Remove the connection pipe and tighten
4
the cap of valve head. The task is then
completed.
Gas Leakage Inspection
Please use gas leakage detector to check if leakage occurs at the
connection of Hexagon screw nut as shown on the right.
If gas leakage occurs, further tighten the connection to stop leakage.

WARNING
!
Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could not reach the
specified capacity.
Procedures of Wiring
Green & Yellow
The naked part of the wire core should be 14 mm and the insulated part of the wire must be push into
G
the terminal for 3 – 4 mm. Then try to pull the individual wire to check if the contact is tight. Improper
insertion may burn the terminal.
Be sure to use only wire specified for the use of air-conditioner.
G
Please refer to the installation manual for wire connection and the wiring technique should meet the
G
standards of electrical installation.
There is a AC voltage drop between the A, B terminals if the power is on. Therefore, be sure to remove
G
the plug from its socket.
