Test run

Before test run

• Before turning on the power supply, carry out the

following procedure.

1) By using 500 V-megger, check that resistance

of 1 MΩ or more exists between the terminal

block L

to L

and the earth (grounding).

If resistance of less than 1 MΩ is detected, do

not run the unit.

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 before operating.

• Do not press the electromagnetic contactor to

forcibly perform a test run. (This is very dangerous

because the protective device does not work.)

• Before starting a test run, set addresses by following

the Installation Manual supplied with the outdoor

unit.

Execute a test run

Operate the unit with the wired remote control as usual.

For the procedure of the operation, refer to the

attached Owner's Manual to the outdoor unit.

A forced test run can be executed in the following

procedure even if the operation stops by thermostat-

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

Do not use the forced test run for cases other than the

test run because it applies an excessive load to the

devices.
