Table 7
12. TEST OPERATION
‹Complete all the “1. Items to be checked after completion of work” on page 4. Please also refer to the
installation manual of the outdoor unit.›
< Precaution before test operation >
1. Be sure to fully open the stop valves of outdoor unit.
2. Keep crank case heater energized for 6 hours or more.
3. Be sure to perform the cooling operation during the test operation.
4. Make sure to remove the cushion materials of fun. (Refer to page 8)
The settings of the BRC1E model remote controller should be switched while referring to the manual supplied
with the remote controller.
The settings of the other remote controller should be switched in accordance with the following procedure.
• Make sure that the installation work for the indoor and outdoor units is all completed.
• Make sure that the following items are all closed: the control box lid of the indoor unit and the outer board
and piping cover of the outdoor unit.
• After completing the refrigerant piping, drain piping, and electrical wiring, clean the interior of the indoor unit
and front panel. Next, perform test operation in accordance with the installation manual supplied with the
outdoor unit in order to protect the unit. (It is recommended that the test operation is performed in the
presence of qualified electrical technician or engineer.)
• If interior work is still unfinished when test operation finishes, explain to the customer that the air conditioner
must not be operated until interior work is completed in order to protect the indoor units. (If the unit is
operated under this condition, paint, glue, and other materials used during the interior finishing work will
contaminate the indoor unit. This may cause water splashes or leakage.)
• If a malfunction occurs and the unit cannot operate, refer to “12-1 HOW TO DIAGNOSE FOR
PROBLEMS”.
• After completing the test operation, press the INSPECTION/TEST OPERATION button once to put the unit
into inspection mode, and make sure the malfunction code is “00” (=normal). If the code reads anything
other than “00”, refer to “12-1 HOW TO DIAGNOSE FOR PROBLEMS”.
• After trial operation, when the fan of indoor unit is spinning and the operation light is flashing, there is a risk
of refrigerant leakage, so please ventilate the room, and contact your dealer (only for R32 refrigerant).
• Press the INSPECTION/TEST OPERATION button four times to return to normal operation mode.
