(B) Use the test run procedure
The purpose of the test run function is to let you control the operation of the unit directly without turning the
unit on or off by thermostat. As indicated in the following procedure, be sure to stop test run operation when
you finish the procedure, or the air conditioner may be damaged.
To protect the air conditioner from overloading, the outdoor unit will not start running for 3 minutes after power
is applied or the unit is turned OFF.
a) Press the TEST / CHK button at the
bottom right on the remote controller.
b Press the ON / OFF operation button to
start the test run.
c) Press the MODE button to select either
COOLING or HEATING mode.
d) When the test run starts, “TEST” shows
on the remote controller’s display.
e) During the test run, the air conditioner
runs continuously and the thermostat does
not control the system.
f) After the test run, be sure to press the
TEST / CHK button once again to finish this
mode and make sure “TEST” is not shown
on the display.
CAUTION
The TEST RUN button is used only for servicing the air conditioner. Do not press this button in normal
operation, or the system may be damaged.
