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

When problems occur?
Before as k for s ervices , pleas e firs t check your unit agains t following.
Air conditioner won't s tart.
Is city power supply normal?
Is leakage current breaker
activated?
Is power supply switch
turned on?
This is very dangerous, please
disconnect power supply
immediately and contact your
dealer.
Power
failure?
Power supply
switch is not
set at ON.
Poor cooling or heating
Are there any obstacles at inlet
or outlet grill?
Are operation controlls
adjusted correctly
as specified?
Is air filter too dirty?
Proper
temp
Are horizontal louvers
at up position (in
heating mode)?
Any doors or windows left
open?
Poor cooling
If there are unexpected heat
sources in the room?
Too many people in the room?
Is there any direct sunlight
in the room?
If your unit still can't work properly after above mentioned
checks, or following problems occur, please stop it immediately
and contact your dealer.
Fuses or circuit breakers often blow out.
Water comes out in cooling/dry operation.
Operation is abnormal or sound is heard.
If the fuse on PC board is broken please change it with the type
of 50F.3.15A/250V.

Ins tallation procedures
Display of whole unit
Try to bring the packed unit to the installation place.
When it is inevitable to unpack the unit, be careful not to damage the unit. Wrap it with
nylon etc.
After unpacking, be sure to put it with the front side of the unit facing up.
Delivery
Facing up
Note: When delivering, don't hold plastic
parts like inlet and outlet grill etc.
Installation of outdoor unit
Selection of installation place
over 30cm
Place strong enough to support the unit and will
not cause vibration and noise.
Place where discharged wind and noise doesn't
cause a nuisance to the neighbors.
Place where is less affected by rain or direct sunlight
and is sufficiently ventilated, or to install a shield.
Place with enough space for smooth air flow.

Fixing of the unit
Fix outdoor unit using M10 bolt to concrete floor horizontally.
If installed on the wall or on top of a roof, bracket should be fixed securely to resist
earthquake or storms.
Use rubber pad during installation against unit vibration.

Ins tallation procedures
Installation of fall-prevention fitting metal:
Fix the fitting metal to the wall by screws so that there is no clearance between them.
With the unit set up vertically, fix the fitting metal to the unit with screws while making
an adjustment at the long portion of the hole so that there is no clearance between the
upper surface and the fitting metal.
Installation of L-shaped metal
Fix to the unit by screws so that there is no clearance between the fitting metal and
the unit.
After confirming that the unit has been set up vertically to the floor, fix it to the floor
by bolt.
Piping connection
1. Connecting method
Apply refrigerant oil at half union and flare nut.
To bend a pipe, give the roundness as large as possible not to crash the pipe.
When connecting pipe, hold the pipe centre to centre then screw nut on by hand,
refer to Fig.
Be careful not to let foreign matters, such as sands enter the pipe.
Forced fastening without centering may
damage the threads and cause a gas leakage.

Arrangement of piping and drainage pipe
After opening inlet grill, you will see a control
box as shown in the Fig.
Remove the cover before working.
Cut away, with a hammer or a saw, the lid for piping according to piping direction.
Insulation material
Drain hose
Connecting electric cable
for indoor and outdoor unit
Copper tube
According to the piping method, connect the piping on indoor unit with union of
connecting pipe.
Arrange the piping as per the wall hole and bind drain hose connecting electric cable and
piping together with polyethylene tape.
Insert the bound piping connecting electric cable and drain hose through wall hole to
connect with outdoor unit.
Arrangement of drain hose
Drain hose shall be placed in under place.
There should be a slope when arrange drain hose. Avoid up and down waves in drain hose.

Ins tallation procedures
3. Piping connection of outdoor unit.
Connect the connecting pipe and inlet and outlet liquid pipe according to the piping
method.
4.Purging method
Discharge the air out of the indoor unit and the refrigerant pipe by vacuumizing
(1) Fasten all the nuts of the indoor and outdoor pipes to make these parts out of leakage.
(2) Under the condition of the complete close of the indoor and outdoor valve center (both
liquid and gas side),dismount the repair valve cap.Vacuumizing through the charge
mouth of the repair valve.
(3) After vacuumizing fasten the repair valve,and dismount the cap of the big and small
stop valve,then loosen the stop valve center completely and fasten the big and small
stop valve.
5.Extra charging amount of the refrigerant
When piping is longer than 5 m, charge additional refrigerant specified in this list.

Others
1. Power supply
Air conditioner must use an exclusive line (over 30A)
When installation air conditioner in a wet place, try to use a circuit breaker against
Current leakage.
For installation in other places, use circuit breaker as far as possible.
The breaker of the air conditioner should be all-pole switch ; and the distance between
its two contacts should be no less 3 mm.
Such means for disconnection must be incorporation in the fixed wiring
2. Pipe cutting and flaring
Be sure to carry out deburring after pipe cutting with a pipe cutter.
Insert flaring tool to make a flare.
