Test run
Before test run
• Before turning on the power supply, carry out the following procedure.
1) Using 500V-megger, check 1MW or more exists between the terminal block 1 to 3 and the earth.
If 1MW or less is detected, do not run the unit. Do not apply to the remote controller circuit.
2) Check the valve of the outdoor unit being opened fully.
• To protect the compressor at activation time, leave power-ON for 12 hours or more be for operating.
How to execute a test run
Using the remote controller, operate the unit as usual.
For the procedure of the operation, refer to the attached Owner’s Manual.
A forced test run can be executed in the following procedure if the operation stops by thermo.-OFF.
In order to prevent a serial operation, the forced test run is released after 60 minutes have passed
and returns to the usual operation.
CAUTION
When the remote controller is used for the first time, it accepts an operation approx. 5 minutes
after the power supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 minute is required to start the operation by the
remote controller.
NOTE
Do not use the forced test run for cases
other than the test run because it applies
an excessive load to the devices.
In case of wireless remote controller
