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 lters. If dirty, clean them.

• Check the outdoor unit to make sure nothing is blocking the air inlet or outlet.

• Check the thermostat is properly set.

• 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 heat-generating appliances are operating in the room.

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.

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 restart 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 re-set after power recovery.

PREHEATING FUNCTION

In the HEAT operation, the indoor fan may not start

for two to ve 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 out d oor unit du r ing the HEAT ope r atio n , a n automatic de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the inside and outside fans stop operating.

• After de-icing is completed, the unit automatically resumes operation in the HEAT mode.

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 efciency.

• 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.
