before operation.

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, firstly turn off the power supply to the unit. Then short CN72 found on the P.C. board. Once completed turn the power to the unit back on and start the unit in FAN only mode. Upon completion of the test do not forget to remove the short circuit on CN72.

•Using the remote controller, check the unit is in normal operation. For the operation procedure, refer to the supplied Owner’s Manual. A forced test operation can be executed in the following procedure under the condition of thermo.-OFF of room temperature.

In order to prevent the test operation from running continuously, the operation will cease after a period of 60 minutes. The unit will then return back to its original operation.

Procedure

Description

 

 

1

Remove a small screw which fixes the nameplate of the receiver unit.

Remove the nameplate of the sensor section by inserting a minus screwdriver, etc into the notch at the bottom

 

of the plate, and set the Dip switch to [TEST RUN ON].

Execute a test operation with button on the wireless remote controller.

, , and

LED flash during test operation.

 

• Under status of [TEST RUN ON], the temperature adjustment from the wireless remote controller is invalid.

 

Do not use this method in the operation other than test operation because the equipment is damaged.

 

 

3

Use either COOL or HEAT operation mode for a test operation.

* The outdoor unit does not operate approx. 3 minutes after power-ON and operation stop.

 

 

4

After the test operation finished, stop the air conditioner from the wireless remote controller, and return Dip

switch of the receiver section as before.

(A 60-minutes timer clearing function is attached to the receiver section in order to prevent a continuous test

 

operation.)

NOTE

Do not use a forced operation in cases other than test operation because it applies an excessive load onto the air conditioner.
