it to the slave unit.
(5) Turn on the main power supply switch again, and as in (1),
change the SECOND CODE No. to "02", individual setting
for the slave unit.
(6) Perform field setting (Refer to 10-1 to 10-6) for the slave

11. TEST OPERATION
Complete all the 1. Items to be checked after the
installation work is completed on page 3. Please also refer
to the installation manual attached to outdoor unit.
(1) The settings of BRC1 E model remote controller should be
performed while referring to the manual attached to the
remote controller.
(2) The settings of the wireless remote controller should be
switched in accordance with the following procedure.
• Make sure that the installation work for the indoor and
outdoor units are 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 attached to 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.)
• In test operation, make sure that fan speed can be
obtained according to the settings.
• 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 indoor 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 air conditioner cannot
operate, refer to 11-1 HOW TO DIAGNOSE FOR
PROBLEMS.
• After completing the test operation, press the INSPEC­
TION/TEST OPERATION button once to put the indoor
unit in inspection mode, and make sure the malfunction
code is "00" (= normal).
If the code reads anything other than "00", refer to
11-1
HOW TO DIAGNOSE FOR PROBLEMS.
• Press the INSPECTION/TEST OPERATION button four
times to return to normal operation mode.
