OPERATION
Maintenance Tips
**Check before operating**
If you plan to idle the heat pump mini-
split for a long time, perform the
following:
(1) Operate the fan for about half a
day to dry the inside of the heat
pump mini-split.
(2) Stop the air heat pump mini-split
and disconnect power. Remove the
batteries from the remote
controller.
(3) The outdoor condenser requires
periodic maintenance and cleaning.
Do not attempt to do this yourself.
Contact your dealer or service
provider:
Check that the wiring is not
broken or disconnected.
Check that the air filter is
installed.
Check if the air outlet or inlet is
blocked after the air heat pump
mini-split has not been used for
a long time.
CAUTION
Do not touch the metal parts of the
heat pump mini-split when
removing the filter. Injuries can
occur when handling sharp metal
edges.
Do not use water to clean inside the
heat pump mini-split. Exposure to
water can destroy the insulation,
leading to possible electric shock.
When cleaning the heat pump mini-
split, first make sure that the power
and circuit breaker are turned off.
Operating Tips
The following events may occur during
normal operation:
1. Compressor protection.
The compressor can't restart for 3
minutes after it stops. The heat
pump mini-split is designed not to
blow cold air on HEAT mode when
the indoor heat exchanger is in one
of the following three situations and
the set temperature has not been
reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan will stop
running when defrosting. Frost may
be generated on the outdoor
condenser during heat cycle when
outdoor temperature is low and
humidity is high resulting in lower
heating efficiency of the heat pump
mini-split.
During this condition heat pump
mini-split will stop heating operation
and start defrosting automatically.
The time to defrost may vary from 4
to 10 minutes according to the
outdoor temperature and the amount
of frost build-up on the outdoor
condenser.
2. A white mist coming out from the
indoor air handler. A white mist
may generate due to a large
temperature difference between air
inlet and air outlet on COOL mode in
an indoor environment that has a
high relative humidity. A white mist
may generate due to moisture
generated from defrosting process
