HEATING

COOL / DRY / HEAT / FAN Models

HEATING PERFORMANCE

A heat pump conditioner heats a room by taking heat from outside

air. The heating efficiency will fall off when the outdoor temperature

is very low. If enough heat is not obtained with this air conditioner,

use another heating appliance in conjunction with it.

For several minutes after the start of heating operation, the indoor

fan will not run until the indoor heat exchanger coil has warmed

up sufficiently. This is because the COLD DRAFT PREVENTION

SYSTEM is operating.

DEFROSTING OF HEAT EXCHANGER

When the outdoor temperature is low, frost or ice may appear on

the heat exchanger coil, reducing the heating performance. When

this happens, a microcomputer defrosting system operates. At

the same time, the fan in the indoor unit stops and the OPERATION

lamp is flashing until defrosting is completed. Heating operation

restarts after several minutes. (This interval will vary slightly

depending on the room and outdoor temperature).
