7. Test run

7.1. Before test run

sAfter completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply.

sUse a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is at least 1.0 MΩ.

sDo not carry out this test on the control wiring (low voltage circuit) termi- nals.

Warning:

Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.

7.2.1.Using wired remote controller (Fig. 7-1)

1 Turn on the power at least 12 hours before the test run.

2 Press the [TEST] button twice. ➡ “TEST RUN” liquid crystal display

3 Press the [Mode selection] button. ➡ Make sure that wind is blown out.

4 Press the [Mode selection] button and switch to the cooling (or heating) mode. ➡ Make sure that cold (or warm) wind is blown out.

5 Press the [Fan speed] button. ➡ Make sure that the wind speed is switched.

6 Check operation of the outdoor unit fan.

7 Release test run by pressing the [ON/OFF] button. ➡ Stop 8 Register a telephone number.

The telephone number of the repair shop, sales office, etc., to contact if an error occurs can be registered in the remote controller. The telephone number will be displayed when an error occurs. For registration procedures, refer to the operation manual for the indoor unit.

7.2.2.Using wireless remote controller (Fig. 7-2)

1Turn on the power to the unit at least 12 hours before the test run.

2Press the TEST RUN button twice continuously.

(Start this operation from the status of remote controller display turned off.)

A TEST RUN and current operation mode are displayed.

3Press the MODE button to activate COOL mode, then check whether cool air is blown out from the unit.
