•Condensation may form on the air outlet if the unit operates continuously in the COOL or DRY mode when humidity is over 80 percent.
WHEN POWER FAILURE OCCURS
This air conditioner has a memory function to store settings when a power failure occurs.
After power recovery, the unit will automatically re- start in the same settings which were active before the power failure, except for timer settings.
If the timers were set before a power failure, they will need to be
PREHEATING FUNCTION
In the HEAT operation, the indoor fan may not start for two to five minutes after the unit is turned on to prevent cold air from blowing out of the unit.
DE-ICING FUNCTION
•When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic
•After
HEATING EFFICIENCY
•The unit employs a heat pump that draws heat from the outside air and releases it into the room. The outside air temperature therefore greatly affects the heating efficiency.
•If the heating efficiency is reduced due to low outside temperatures, use an additional heater.
•It takes time to warm up and heat the entire room because of the forced air circulation system.
BEFORE CALLING FOR
SERVICE
The following conditions do not denote equip- ment 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
ODORS
Carpet and furniture odors that entered into the unit may be sent out from the unit.
BEFORE CALLING FOR
SERVICE
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.
SWISHING NOISE
The soft, swishing noise is the sound of the refrigerant 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 temperature and the air discharged by the unit.
•In the HEAT operation, water vapour may flow out of the outdoor unit during
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.
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.
•Check the outdoor unit to make sure nothing is blocking the air inlet or outlet.
•Check the thermostat is proper setting.
•Make sure windows and doors are closed tightly.
•A large number of people in the room can prevent the unit from achieving the desired temperature.
•Check whether any
IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
•Check whether the remote control batteries have become old and weak.
•Try to send the signal again with the remote control pointed properly towards the unit’s signal receiver window.
•Check whether the remote control batteries are installed with the polarities properly aligned.
Please call for service when OPERATION lamp, TIMER lamp and/or PLASMACLUSTER lamp on the unit blink.
