Trouble Shooting
Followings are not problems
Sound of water flowing is
not a problem.
Sound of cracking is heard.
Smell are generated.
During operation, white fog or steam
comes out from the indoor unit.
No outlet air or fan speed can't be changed
in dry mode.
In cooling operation, unit switches to
blowing operation.
Won't start?
In heating operation, water or steam are
blown out of outdoor unit.
In heating operation, indoor fan won't stop
even if unit is stopped.
During unit operation or at stop, a swishing or
gurgling noise may be heard. This noise is generated
by refrigerant flowing in the system.
Unit will not restart after stop.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperature changes.
This is because the system circulates smells from the
interior air such as the smell of cigarettes or the
painting on the furniture.
When unit is running at places like restaurant, etc. where
dense edible oil fumes always exist, this will happen.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to blowing operation for a
while then resume cooling operation.
Though ON/OFF button is set
to ON, unit won't resume cooling,
dry or heating operation
in 3 min after it is stopped, this
is because of 3-min-delay
protection circuit. Please wait 3 minutes
Unit will reduce fan speed repeatedly and automatically
if room temp. is too low in dry operation.
This occurs when frost accumulated
on the outdoor unit is removed.
(during defrosting operation)
After unit stop, indoor fan will go on running
until indoor unit cools down.

Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
Heat-pump air conditioners heat your entire room
by recirculating air throughout the room, with the
result that some time may be required after first
starting the air conditioner until the room is heated.
This air conditioner operates on the heat-pump
principle, absorbing heat from outdoor air and
transferring that heat indoors. As a result, the
operating performance is reduced as outdoor air
temperature drops. If you feel that insufficient
heating perfomance is being produced, we
recommend you use this air conditioner in
conjunction with another kind of heating
appliance.
Instructions relating to heating (*) are applicable
only to "HEAT & COOLTYPE".
When using the Heating mode under conditions of
low outdoor air temperature high humidity, frost
may form on the outdoor unit, resulting in reduced
operating performance.
In order to prevent this kind of reduced
performance, this unit is equipped with a
Microcomputer-controlled Automatic Defrosting
function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will
operate briefly (for about 7 to 15 minutes).
During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.
*Trouble alarming performance
During operation, when there is any trouble,
the power indicator lamp will flash.
Operation Tips
Temperature and Humidity Range
If the air conditioner is used under higher temperature condition than those listed, the built-in protection
circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is
used under conditions of lower temperature than those listed above, the heat-exchanger may freeze, leading
to water leakage and other damage.
Do not use this unit for any other purposes except for the Cooling, (*) Heating, Dehumidifying, and air-
circulation of rooms in ordinary dwellings.
The wiring method should be in line with the local wiring standand.
The waste battery should be disposed properly.
If the fuse on PC board is broken, please change it with the type T 3.15A/250VAC.
