when the heat pump mini-split
restarts in HEAT mode operation
after defrosting.
3. Hissing sound from the heat
pump mini-split.
You may hear a low hissing sound
when the compressor is running or
has just stopped running. This sound
is from the refrigerant flowing
through the system or coming to a
stop.
You may also hear a low "squeak"
sound when the compressor is
running or has just stopped running.
This is caused by heat expansion
and cold contraction of the plastic
parts in the heat pump mini-split
when the temperature is changing.
When power is first turned on, a
noise may be heard due to louver
restoring to its original position. This
is normal operation.
4. Dust is blown out from the indoor
air handler.
This is a normal condition when the
heat pump mini-split has not been
used for a long time or during first
use of the heat pump mini-split.
5. A peculiar smell comes out from
the indoor air handler.
This is caused by the indoor air
handler giving off smells permeated
from building material, from furniture,
or smoke.
6. Compressor functionality
When the indoor temperature
reaches the set temperature, the
compressor will stop automatically
and the heat pump mini-split turns to
FAN only mode. The compressor will
start again when the indoor
temperature rises on COOL mode or
falls on HEAT mode to reach the set
point.
7. Dripping water may form on the
surface of the indoor air handler
when cooling in a high relative
humidity (relative humidity higher
than 80%). This is due to the angle
of the horizontal louver being set too
small. Adjust the horizontal louver to
the maximum air outlet position and
select HIGH fan speed.
8. Heating Mode
The air heat pump mini-split draws
in heat from the outdoor condenser
and releases it via the indoor air
handler during heating operation.
When the outdoor temperature
falls, heat drawn in by the heat
pump mini-split decreases
accordingly. At the same time, heat
loading of the heat pump mini-split
increases due to larger difference
between indoor and outdoor
temperature. If a comfortable
temperature can't be achieved by
the air heat pump mini-split, we
suggest you use a supplementary
heating device.
9. Auto-restart function.
Power failure during operation will
stop the heat pump mini-split
completely. When the power
restores, the heat pump mini-split
restarts automatically with all the
previous settings preserved by the
memory function.
10. Lightning
Lightning nearby may cause the
heat pump mini-split to malfunction.
Disconnect the power to the heat
pump mini-split and then re-
connect the power to the heat
pump mini-split. Push
the ON/OFF button on the remote
controller to restart operation.
