÷ If the unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to
prevent fuse blowouts.
÷ Whenever the Power is disconnected and then reconnected to
a power outlet, the protection circuit will operate for about 3
minutes, preventing unit operation during that period.
÷ During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioner’s piping may be
heard. Also, noise may be particularly noticeable for about 2
to 3 minutes after starting operation (sound of coolant flowing).
÷ During operation, a slight squeaking sound may be heard. This
is the result of minute expansion and contraction of the front
cover due to temperature changes.
÷ During Heating operation, a sizzling sound may be heard
occasional. This sound is produced by the Automatic Defrosting
operation.
÷ Some smell may be emitted from the indoor unit. This smell is
the result of room smells (furniture, tobacco, etc.) which have
been taken into the air conditioner.
÷ During Cooling or Dry operation, a thin mist may be seen
emitted from the indoor unit. This results from the sudden
Cooling of room air by the air emitted from the air conditioner,
resulting in condensation and misting.
÷ During Heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to
Automatic Defrosting operation.
÷ When Heating operation is started, fan speed is temporarily
very low, to allow internal parts to warm up.
÷ During Heating operation, the unit will temporarily stop
operation (between 7 and 15 minutes) as the Automatic
Defrosting mode operates. During Automatic Defrosting
operation, the OPERATION Indicator Lamp will flash.
÷ The fan may operate at very low speed during Dry operation
or when the unit is monitoring the room’s temperature.
÷ During SUPER QUIET operation, the fan will operate at very
low speed.
÷ In the monitor AUTO operation, the fan will operate at very
low speed.
÷ During Heating operation, water may be produced from the
outdoor unit due to Automatic Defrosting operation.
÷ When there is frost on the outdoor unit when heating operation
is stopped, defrosting will be performed automatically.
At this time, OPERATION Indicator Lamp will flash, and
operation will stop after the outdoor unit has run for several
minutes.
