TEST RUN

Before test operation
• Before turning on the power supply, carry out the following items.
1) Using 500V-megger, check there is 1MΩ or more between the
terminal block of the power supply and the earth. If 1MΩ or less
is detected, do not run the unit.
2) Check that all the valves of the outdoor unit are fully opened.
• Never push the electromagnetic contactor to carry out a forced test operation.
(It is very dangerous because a protective device does not work.)
How to execute test operation
• To carry out a fan operation in a single indoor unit, turn off the power once, short CN72 on P.C. board, and then
turn on the power again. (Start the unit in FAN mode.) In this case, do not forget to clear short-circuit of CN72 after
test operation.
• Using the remote controller, check the operation in the usual operation. For the operation procedure, refer to the
attached Owner's Manual.
A forced test operation can be executed in the following procedure under condition of thermo-OFF of room
temperature.
In order to prevent a serial operation, the forced test operation is released after 60 minutes and returns to the
usual operation.
NOTE
Do not use a forced operation in cases other
than test operation because it applies an
excessive load to the air conditioner.
In case of wired remote controller
