Before Calling For Service - Sharp AY-XP7FR Mode D'emploi

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 BUZZING NOISE EMITTED
This is a sound emitted when the unit is generating
Plasmacluster ions.
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.
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 con-
trol batteries have become old
and weak.
Please call for service when TEMPERATURE INDICATOR on the indicator panel blink.
SWISHING NOISE
The soft, swishing noise is the sound of the refrig-
erant flowing inside the unit.
WATER VAPOUR
• In the COOL and DRY operation, water vapour
can sometimes be seen at the air outlet due to
the difference between the room air tempera-
ture and the air discharged by the unit.
• In the HEAT operation, water vapour may flow
out of the outdoor unit during de-icing.
THE OUTDOOR UNIT DOES NOT
STOP
After stopping the operation, the outdoor unit will
rotate its' fan for about a minute to cool down the
unit.
ODOR EMITTED FROM THE
PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated from the
Plasmacluster Ion generator. The ozone
concentration is very small, posing no adverse
effect on your health. The ozone discharged into
the air rapidly decomposes, and its density in the
room will not increase.
Check the outdoor unit to make
sure nothing is blocking the air in-
let or outlet.
A large number of people in the
room can prevent the unit from
achieving the desired tempera-
ture.
Try to send the signal again with
the remote control pointed prop-
erly towards the unit's signal re-
ceiver window.
E-19
Check the thermostat is proper
setting.
Check whether any heat-gen-
erating appliances are operat-
ing in the room.
Check whether the remote con-
trol batteries are installed with
the polarities properly aligned.
