11. 2 PERFORM A TEST RUN ACCORDING TO THE
OUTDOOR UNIT’S INSTALLATION MANUAL
(1) Make sure the control box of the unit is closed before
turning on power.
(2) Make a test run following the operation manual of the
outdoor unit.
• The operation lamp of the remote controller will flash
when an malfunction occurs. Check the malfunction code
on the liquid crystal display to identify the point of trouble.
An explanation of malfunction codes and the correspond-
ing trouble is provided in “CAUTION FOR SERVICING” of
the outdoor unit.
If the display shows any of the following, there is a possi-
bility that the wiring was done incorrectly or that the
power is not on, so check again.
11. 3 RUN THE HUMIDIFIER
<VKM-GBMV1 SERIES ONLY>
(1) Check that the water supply piping is connected securely.
(2) Open the water supply shut-off valve. (No water will be
supplied at this time.)
(3) Run the Heat Reclaim Ventilator unit in heating mode.
(See the operating manual included with the indoor unit
for details on how to run the unit in heating mode.)
The water supply will start and the humidifier will begin
operation.
(4) After starting heating (humidifying), the sound of the
water supply solenoid valve will be heard every
3 or 4 minutes (a clicking sound), so listening for that
clicking sound let the unit run for 30 minutes to make
sure that humidifying operation is normal.
CAUTION
• If carpentry work is not completed when a test run is fin-
ished, tell the customer not to run the humidifier for the pro-
tection of indoor unit and Heat Reclaim Ventilator until it is
completed.
• If the humidifier is run, paint, particles generated from
adhesive and other materials used for carpentry work may
cause Heat Reclaim Ventilator to get dirty, causing splash
or leakage of water.
