CAUTIONS FOR INSTALLATION
The system should be applied to places as
office, restaurant, residence and the like.
The system should be installed by your
dealer or a professional installer.
When you need some optional devices such as a humidifier, electric heater, etc., be sure to use the products
which are recommended by us. These devices should
be attached by a professional installer.
Application to inferior environment such as an engineering shop, could cause equipment malfunction and
serious injury or death.
Installation by yourself is not encouraged because
it could cause such problems as water leakage,
electrical shock or fire accident by some improper
handing.
Installation by yourself is not encouraged because it
could cause such problems as water leakage, electrical
shock or fire accident by some improper handing.
Do not install nearby the place where may
have leakage of flammable gas.
Depending on the place of installation, a
circuit breaker may be necessary.
Drain pipe should be arranged to provide a
positive draining.
If the gas leakes and gathers around, it may cause the
fire.
Unless the circuit breaker is installed, it could
cause elecrical shocks.
Where strong winds may prevail, the
system should be fixed securely to prevent
a collapse.
Install on the place where can endure
the weight of air conditioner.
Make sure the system is grounded.

When the air conditioner does not operate properly after you have checked the above mentioned
items or when the following phenomenon is observed, stop the operation of the air conditioner
and contact your sales dealer.
The fuse or breaker often shuts down.
Water drops off during cooling operation.
There is a irregularity in operation or abnormal sound is audible.
When the CHECK lamp (red) flickers, an irregularity has occurred in the air conditioner.
Note:
This unit has a function of automatic restart system after recovering power stoppage. Please contact the sales
dealer if it is not required.

MALFUNCTION
The followings are not malfunction
Shuru
Shuru
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.
Water flowing
sound is heard.
This is caused by heat expansion or contraction of plastics.
Cracking sound is heard.
It smells.
Air which blows out from the indoor unit sometimes smells.
The smell results from residents of tobacco smoke or cosmetics
stuck inside of unit.
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 exchanger.
During operation,
white fog comes
out of indoor unit.
Unit does
not start
Wait for
three
minutes
It is switched into the FAN mode
during cooling.
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 conditioner is
stopped. Because the protecting circuit is activated.
(During this time air conditioner operates in fan
mode.)
The air conditioner can not be
restarted soon after it stops.
Air does not blow or the fan
speed can not be changed during
dehumidifying
During operation, operation mode
has changed over automatically.
Water or steam generates from
the outdoor unit during heating.
When it is excessively cooled during dehumidifying, the blower
automatically repeats reducing and lowering the fan speed.
Isn't the AUTO mode selected?
In the case of AUTO mode, operation mode is changed automatically from cooling to heating or vise-versa according to the room
temperature.
This results when frost accumulated on the outdoor unit is removed
(during defrosting operation).
