in case the cable length exceeds 20m)
• For power supply cable, securely clamp a round terminal to each end of the stripped cable.
• Use a cable which is not lighter than polychloroprene sheathed flexible cord (code designa
-
tion 60245 IEC 57).
(2) Remove the control box cover and cable cover.
(3)
Remove the cable holder and connect the cables.
Be sure that the terminal connections are as specified.
(4) Fix the cable sheaths with the cable holder and the screw.
(5) Double-check that the cables are securely in place.
(6) Place the control box cover back in the reverse order.
*If the cable sheaths are not firmly secured with the cable holder, put the
SHEET on the cable holder base.
Caution:
• Be sure to put the cable leads deep into the terminal
board and tighten up the screws. Poor contact can
cause overheating or fire, or malfunction.

PUMP DOWN
(Pump down is adopted in the case of unit removal for re-installation, abandonment, repair etc.)
Pump down is to collect the refrigerant into the outdoor unit by control of the 2 and 3-way valves and the compressor.
(1) Stop the air conditioner operation.
(2) Remove both valve shaft caps of the 2 and 3-way valves.
(3) Run the air conditioner at cooling test run mode (Refer to 11 TEST RUN). If pump down is performed at normal
cooling operation, the protection system may engage and stop the operation.
(4) After 5~10 minutes, fully close the 2-way valve by turning the hexagon socket screw key clockwise.
(5) After 2~3 minutes, immediately close the 3-way valve fully.
(6) Stop the test run operation.
(7) Replace both valve shaft caps tightly.
(8) Disconnect both refrigerant pipes.
Caution:
Make sure that the compressor is turned off before removing the refrigerant pipes.
Otherwise, it will cause burst and injury

(1) Start the operation with the remote control.
(2) To start test run in cooling, hold down the AUX button on the unit for over 5 seconds until a beep sound is heard
and an operation lamp flashes.
(3) To put the system in the heating test run mode, select heat mode on the remote control while the unit is in cool
-
ing test run mode.
(4) Make sure the system runs well. To stop the operation, press the AUX button again.
Is the specified power supply voltage used?
Is the connecting cable fixed to terminal board firmly?
Is the earth wire connected properly arranged?
Is the drainage properly?
Is the indoor unit hooked to the mounting plate firmly?
Is there any gas leakage at the pipe connection?
• Fit a disconnect switch, having a contact separation of at least 3mm in all poles,
to the electricity power line.
Explanation to customer
• Explain to the customer how to use and maintain the system, referring to the
operation manual.
• Ask the customer to carefully read the operation manual.
• When the system has been set up, hand the installation manual to the customer.
