Toshiba Test Run Instructions for MMK Air Conditioners

11 TEST RUN

Before test operation WARNING

• 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.

To protect the compressor at starting time, keep power-ON condition before 12 hours or more.

•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

•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.
