WARNING OPERATION
Heat pump type warming
With the heat pump type warming, the mechanism of heat pump that concentrate heat of
outdoor air with the help of refrigerant to warm the indoor space, is utilized.
Defrosting operation
when a room is warmed with a heat pump type air conditioner, frost accumulates on the
heat exchanger of outdoor unit along with the drop of indoor temperature. Since the accu-
mulated frost reduces the effect of warming, it is necessary to automatically switch the op-
eration to the defrosting mode. During the defrosting operation heating operation is inter-
rupted.
Atmospheric temperature and warming capacity
Warming capacity of heat pump type air conditioner decrease along with the drop of out-
door temperature.
When the warming capacity is not sufficient, it is recommended to use another heating im-
plement.
Period of warm-up
Since the heat pump type air conditioner employs a method to circu-
late warm winds to warm the entire space of a room, it takes time be-
fore the room temperature rises.
It is recommendable to start the operation a little earlier in a very
cold morning.
