Before Calling For Service - Sharp AY-AP18CJ Operation Manual

BEFORE CALLING FOR SERVICE

The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the internal mechanisms. Wait 3
minutes before operating the unit.
UNIT DOES NOT SEND OUT WARM AIR
The unit is preheating or de-icing.
ODORS
Carpet and furniture odors that entered into the
unit and the air conditioner's inner component
odors at the early stage of installation may be
sent out from the unit.
CRACKING NOISE
The unit may produce a cracking noise. This sound
is generated by the friction of the front panel and
other components expanding or connecting due to
a temperature change.
A LOW BUZZ NOISE EMITTED
This is a sound emitted when the unit is generating
ion clusters.
If the unit appears to be malfunctioning, check the following points before calling
for service.
IF THE UNIT FAILS TO OPERATE
• Check to see if the circuit breaker has tripped or the fuse has blown.
• Check if the louvre unit is properly installed. All lamps on the indicator panel will blink when
the louvre unit is not properly installed.
IF THE UNIT FAILS TO COOL (OR HEAT) THE ROOM EFFECTIVELY
Check the filters. If dirty,
clean them.
Make sure windows and
doors are closed tightly.
IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
Check whether the remote
control batteries have be-
come old and weak.
Please call for service when OPERATION Lamp and TIMER Lamp on the indicator panel blink.
Check the outdoor unit to
make sure nothing is blocking
the air inlet or outlet.
A large number of people in
the room can prevent the unit
from achieving the desired
temperature.
Try to send the signal again
with the remote control
pointed properly towards the
unit's signal receiver window.
16
SWISHING NOISE
The soft, swishing noise is the sound of
the refrigerant flowing inside the unit.
WATER VAPOUR
• In the COOL and DRY operation, wa-
ter vapour can sometimes be seen at
the air outlet due to the difference
between the room air temperature and
the air discharged by the unit.
• In the HEAT operation, water vapour
may flow out of the outdoor unit dur-
ing de-icing.
ODOR EMITTED FROM THE
PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated
from the ionizer. Density of the ozone is
very little, having no adverse effect over
your health. The ozone released into
the air will decompose soon, and its den-
sity in the room will not increase.
Check the thermostat is
proper setting.
Check whether any heat-
generating appliances are
operating in the room.
Check whether the remote
control batteries are in-
stalled with the polarities
properly aligned.
