DEFROSTING OF HEAT EXCHANGER
OUTDOOR UNIT "STANDBY"
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 STANDBY lamp remains lit until defrosting is completed.
Heating operation restarts after several minutes. (This interval
will vary slightly depending on the room and outdoor
temperature).

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.
