troubleshooting
Before calling for service, check the following:
Problem Possible cause and points to check
The system does
not restart imme-
diately.
• After stopping the unit, it won’t restart im-
mediately until 3 minutes have elapsed to
protect the system.
• When the electric plug is pulled out and rein-
serted, the protection circuit will work for 3
minutes to protect the air conditioner.
Noise • During unit operation or at stop, a swishing
or gurgling noise may be heard. At first 2-3
minutes after unit start, this noise is more no-
ticeable. (This noise is generated by refriger-
ant flowing in the system.)
• During unit operation, a cracking noise may
be heard. This noise is generated by the case
expanding or shrinking because of tempera-
ture changes.
• Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
Bad odor • This is because the system circulates odors
from the interior air such as the odor of furni-
ture, paint, cigarettes.
Mist or steam are
blown out
• During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
In dry mode, fan
speed can’t be
changed.
• In DRY mode, when room temperature be-
comes lower than temperature setting +2 °C,
unit will run intermittently at LOW speed re-
gardless of FAN setting.

Page: 70

Unit won't start. • Is power plug inserted?
• Is there a power failure?
• Is fuse blown out?
Poor cooling. • Is the air filter dirty? Normally it should be
cleaned every 15 days.
• Are there any obstacles before inlets and out-
lets?
• Is temperature set correctly?
• Are there some doors or windows left open?
• Is there any direct sunlight through the win-
dow during the cooling operation? (Use cur-
tains).
• Are there too much heat sources or too many
people in the room during cooling operation?

connection
• Use the same method on indoor unit. Loosen the screws on termi-
nal block and insert the plugs fully into terminal block, then
tighten the screws.
• Insert the cable according to terminal number in the same manner
as the indoor unit.
• If wiring is not correct, proper operation can not be carried out
and controller may be damaged.
• Fix the cable with a clamp.
attaching a drain elbow
• If a drain elbow is used, please attach it as fig-
ure. (Note: Only on heat pump units.)
using a vacuum cleaner as purging method
1. Detach the service port's cap of 3-way valve, the valve rod's cap
for 2-way valve and 3-way's, connect the service port into the pro-
jection of charge hose (low) for gauge manifold. Then connect
the projection of charge hose (center) for gauge manifold into
vacuum pump.
2. Open the handle at low in gauge manifold, operate vacuum
pump. If the scale moves of gauge (low) reach vacuum condition
in a moment, check 1 again.
3. Vacuum for over 15 minutes and check the level gauge which
should read -0,1 MPa (76 cm Hg) at low pressure side. After the
completion of vacuum, close the handle "LO" in gauge manifold
and stop the operation of the vacuum pump. Check condition of
the scale and hold it for 1-2 min. If the scale moves back in spite
of tightening, make flaring work again, the return to the begin-
ning of 3.
4. Open the valve rod for the 2-way valve to an angle of
anticlockwise 90 degrees. After 6 seconds, close the 2-way valve
and make the inspection of gas leakage.
5. No gas leakage?
In case-of gas leakage, tighten parts of pipe. If leakage stops,
then proceed to step 6.
If it does not stop, discharge whole refrigerants from the service
port. After flaring work again and vacuum, fill up prescribed re-
frigerant from the gas cylinder.
6. Detach the charge hose from the service port, open 2-way valve
and 3-way. Turn the valve rod anticlockwise until hitting lightly.

7. To prevent gas leakage, turn the service port's cap. The valve rod's
cap for 2-way valve and 3 way's a little more than the point
where the torque increases suddenly.
8. After attaching each cap, check for gas leakage around the caps.

CAUTION
• If the refrigerant of the air con-
ditioner leaks, it is necessary to
discharge all the refrigerant.
Vacuum first, then charge the
liquid refrigerant into air condi-
tioner according to the amount
marked on the name plate.
• Please do not let other cooling
medium except the specified
one (R410A) or air enter into
the cooling circulation system.
Otherwise there will be abnor-
mal high pressure in the system
to make it crack and lead to
personal injuries.
