helpful for a better air circulation.
As warm air flows upward in HEA

T mode, adjusting air flow downward will be much more
helpful for a better air circulation.
Be careful not to catch a cold when cold air blows downward.
It is harmful to your health in summer to go frequently in and out of places where temp.difference
is above 7 C . Temp. difference of 3-5 C will remove your fatigue.
More than this, unit's load can be reduced and power consumption cut down as well. So, you'd
better set a temp. diff of 3-5 C between indoor and outdoor temp. in COOL mode.

Water flowing
sound is heard.

When the air conditioner is started, when the compressor starts or
stops during operation or when the air conditioner is stopped, it
sometimes sounds "shuru shuru "or" gobo gobo". It is the flowing
sound of the refrigerant, and it is not a trouble.

Cracking sound is heard.

It smells.

This is caused by heat expansion or contraction of plastics.
Air which blows out from the indoor unit sometimes smells.

The smell results from residents of tobacco smoke or cosmetics stuck
inside of unit.

During operation,
white fog comes
out of indoor
unit.

It is switched into the FAN
mode during cooling.

The air condi­tioner can not

When the air conditioner is used at restaurant etc. where dense edible
oil fume is always exists, white fog sometimes blows out of air outlet
during operation.
In this case consult sales dealer for cleaning the heat exchange

r.

To prevent frost from being accumulated on the indoor unit heat ex­changer

, it is sometimes automatically switched to the FAN mode

but it will soon return to the cooling mode.

Even if the operation switch is turned on, cooling*
dehumidifying or heating is not operable for three
minutes after the air conditioner is stopped. Because
the protecting circuit is activated.
(During this time air conditioner operates in fan mode.)

When it is excessively cold during dehumidifying, the blower auto­matically repeats reducing and lowering the fan speed.

This results when frost accumulated on the outdoor unit is removed
(during defrosting operation).

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 accu­mulated frost reduces the effect of warming, it is necessary to automatically switch the op­eration to the defrosting mode. During the defrosting operation heating operation is inter­rupted.

Atmospheric temperature and warming capacity
Warming capacity of heat pump type air conditioner decrease along with the drop of out­door temperature.
When the warming capacity is not sufficient, it is recommended to use another heating im­plement.

Period of warm-up
Since the heat pump type air conditioner employs a method to circu­late warm winds to warm the entire space of a room, it takes time be­fore the room temperature rises.
It is recommendable to start the operation a little earlier in a very
cold morning.

IS THE UNIT INSTALLED CORRECTLY?

Confirm the following items for safe and comfortable use of air conditioner.
The installation work is to be burden on the sales dealer, and do not conduct it by yourself.

Installation place

Avoid installing the air conditioner
near the place where possibility of in­flammable gas leakage exists.

Install the unit at well ventilated
place.

Install the air conditioner firmly
