Trouble shooting
Before asking for service, check the following first.
Normal
Performance
inspection
Phenomenon
The system does not restart
immediately.
Noise is heard
s are generated.
Smell
Mist or steam are blown out.
Cause or check points
When unit is stopped, it won't restart
immediately until 3 minutes have elapsed
to protect the system.
When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
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
noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may
be heard. This noise is generated by the
casing expanding or shrinking because of
temperature changes
Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
This is because the system circulates smells
from the interior air such as the smell of
furniture, cigarettes.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Multiple
check
Does not work at all.
Poor cooling
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
Is the air filter dirty? Normally it should be
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Is there any direct sunlight through the
window during the cooling operation?(Use
curtain)
Are there too much heat sources or too many
people in the room during cooling operation?

3. Piping connection
Connecting method
To bent a pipe, give the roundness as large as possible not to crash the pipe.
When connecting pipe, hold the pipe center to center then screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands enter the pipe.
Piping connection of the indoor unit
1. 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, w ith hammer or a saw, the lid for piping according to piping direction.
Drain hose
Copper tube
Insulation material
According to the piping method, connect the piping on indoor unit with union of connection 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 hoes through wall hole to connect
with outdoor unit.
2. Arrangement 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.
If humidity is high, drain pipe(especially in room and indoor unit) must be covered with
installation material.

1. Piping connection of the outdoor unit
Connecting the connecting pipe and inlet and
outlet liqued pipe
according to the piping method.
2.The connecting method of U-model terminal block:
Release the screws, put the connecting wire's U-model terminal block between the screw and
terminal-block Base, then tighten the screws. Draw the wire lightly to make sure the block have
been compacted.
Purging Method:
Push the air out of the indoor unit
and piping as followes:
(1) Remove the valve cap on 2-way
valve in outdoor unit.
(2) Loosen by 1/2 turn the flare nut of
gas pipe, which is conneted to
3-way valve.
o
(3) Loosen 2-way valve by 90
using
hexagon wrench, and after approx.
6 sec tighten it up. Gas comes out
through flare nut on wide pipe. If no
gas is discharged, tighten flare nut
with specified torque.
(4) Open 2-way and 3-way valves
using specified torque.
(5) Tighten the caps on the valves
with specified torque.

Note: When extending piping, air inside piping shall be removed by using external refrigerant gas,
charge according to the following list.
Brand new outdoor unit is charged 50g or 80g(24k) more refrigerant than regulated weight. Only for
first installation, this extra 50g or 80g(24k) can be used to purge airin pipes.
During this procedure, 50g or 80g(24k) refrigerant will be discharged in piping.(This must be
strictly controlled within 90

Note: When additional refrigerant is necessary, first purge air out of connecting pipe by external gas,
then drive out the excessive rerigerant by purging method.
Brand new unit is charged 80g more refrigerant than spec. This is only for first instaltion to purge air
in the indoor unit and connecting pipe.
When piping is longer than 5m, charge additional refrigerant specified in this list.
