Test Operation

Note: When power is supplied to the outdoor unit, it will check for and verify communications

with the indoor units.

2. Ensure that the front of the outdoor unit is closed.

3. Press and hold button K1 for 5 seconds to run the test operation (see Table 22, p. 41.)

• During the test operation, the compressor is restricted from operating.

• UP (for “unprepared”) will appear on the digital display. When the test operation has

completed, the display will clear.

• The test operation may continue from 30–50 minutes, depending on the operating status.

• During the test operation, noise may occur due to valve inspection. (Examine the unit if

abnormal noises continue to occur.)

4. When the test operation ends, use VRF Enterprise Management Software or VRF Auto-

Commissioning Tool to issue a test results report. If any items in the report are marked with an

“inspection required” sign, refer to the service manual for information on correcting the items

and run the test operation again.

5. Ensure the following:

• The system has the correct refrigerant amount (see “Refrigerant detection operation” p. 46)

after the unit has been operating in cooling mode for at least 30 minutes

• Cooling/heating operation runs normally.

• There are no abnormal operating noises from indoor or outdoor units.

• During cooling operation, the indoor units drain properly.

their reference.
