● 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 electrical breaker is turned off then on again, the protection circuit

will operate for about 3 minutes, preventing unit operation during that period.

● When Heating operation is started, indoor unit's fan may temporarily stop, to

allow internal parts to warm up.

● During Heating operation, if the room temperature rises above the thermostat

setting, the outdoor unit will stop, and the indoor unit's fan will stop. If you wish to

warm the room further, set the thermostat for a higher setting.

● During oil recovery operation, the air flow may stop for approximately 10 minutes.

● During Heating operation, the unit will temporarily stop operation (between 4 and

15 minutes) as the Automatic Defrosting mode operates.

● The fan may operate at low speed during Dry operation or when the unit is moni-

toring the room's temperature.

● During operation, a slight squeaking sound may be heard. This is the result of

minute expansion and contraction of the panel due to temperature changes.

● During Heating operation, a sizzling sound may be heard occasionally. 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 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 the Automatic Defrosting operation.

● During Heating operation, water may be produced from the outdoor unit due to

the Automatic Defrosting operation.
