Kelvinator Air Conditioning
Normal function of the air conditioner
The following symptoms do not indicate air conditioner
malfunction.
Problem
Cause
After pressing the
start key, the unit is
not started by the
microprocessor for
3 minutes.
It is for the protection of the
compressor, please wait .
Low noise can
be heard
The crackling noises are caused by
the contraction and expansion of the
front panel in response to temperature
differences.
The clicking noise may be caused
by the fan or the compressor when
switching on or off.
You may hear moving water. This is
not a fault. The refrigerant in the air
conditioner may have expanded.
Odd smell in the room
The air conditioner also circulates the
transpiration from the walls, carpets,
smoke, furniture and clothing in the air.
Water drops from the
indoor unit
Dripping water may generate on
the surface of the indoor unit when
cooling in a high relative humidity
(RH more than 80%). Adjust the
horizontal louver to the maximum air
outlet position and select HIGH
fan speed.
Air is not blown out
immediately in
heat mode.
The unit 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 started.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan stop
running when defrosting (Cooling
and heating models only).
The unit turns to
Fan mode from
cool or heat mode
automatically
When the room temperature reaches
the temperature setting on air
conditioner, the compressor will stop
automatically, and the air conditioner
turns to FAN only mode.
The compressor will start again
when the room temperature rises on
COOL mode or falls on HEAT mode
(For cooling & heating models only)
to the set point.
• You can 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 unit when the temperature
is changing.
• A noise may be heard due to louver restoring to its
original position when power is first turned on.
4 Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner
has not been used for a long time or during first use
of the unit.
5 A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit circulating smells
permeated from building material, from furniture,
or smoke.
6 The air conditioner turns to FAN only mode from
COOL or HEAT mode.
When indoor temperature reaches the temperature
setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to FAN
only mode.
The compressor will start again when the indoor
temperature rises on COOL mode or falls on HEAT
mode to the set point.
7
Dripping water may generate on the surface of the
indoor unit when cooling in a high relative humidity
(relative humidity higher than 80%). Adjust the horizontal
louvre to the maximum air outlet position and select
HIGH fan speed.
8 Heating mode
The air conditioner draws in heat from the outdoor
unit and releases it via the indoor unit during heating
operation. When the outdoor temperature falls, heat
drawn in by the air conditioner decreases accordingly.
At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and
outdoor temperature.
If a comfortable temperature can't be achieved by the
air conditioner, we suggest you use a supplementary
heating device.
9 Auto-restart function
Power failure during operation will stop the unit
completely.
For the unit without Auto-restart feature, when the
power restores, the OPERATION indicator on the indoor
unit starts flashing. To restart the operation, push the
ON/OFF button on the remote control. For the unit with
Auto-restart feature, when the power restores, after a
delay of 3 minutes to protect the compressor the unit
restarts automatically with all the previous settings
preserved by the memory function.
10
Lightning or a car wireless telephone operating nearby
may cause the unit to malfunction. Disconnect the unit
from power and then re-connect the unit with power
again. Push the ON/OFF button on the remote control
to restart operation.
