Maintenance
After season maintenance
Before season maintenance
Trouble shooting
Followings are not problems
Let the unit run in Fan mode for half a day in a
fine weather to dry completely the unit inside.
Clean air filter and indoor unit,
cover outdoor unit after
cleaning.
Turn off the unit and pull out
power plug.
There might be certain power
consumption even if unit is stopped.
Check if there are obstacles at inlet and outlet of indoor and outdoor unit,
whick will reduce unit ef
ficiency.
Don't fail to attach air filter after making sure it is cleaned.
Dust will enter into unit causing damages or faults if it is
running without air filter
.
To protect compressor at start, please connect external
power supply to the unit 12 hrs prior to starting.
Also
please keep the power supply switch ON during the whole season.
Sound of water flowings are not
problems.
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 cracking is heard.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperatuer changes.
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.
In cooling operation, unit switches to fan
operation.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to fan operation for a
while then resume cooling operation.

Followings are not problems
Unit will not restart after stop.
Won't start?
No outlet air or fan speed can't be changed
in dry mode.
In heating operation, water or steam are blown
out of indoor unit.
In heating operation, indoor fan won't stop even
if unit is stopped.
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.
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 stops, indoor fan will go on running until indoor
unit cools down.
Please wait 3 minutes

When problems occur?
Air conditioner won't start.
Before ask for services, please first check your unit against following.
Is power supply switch
turned on?
Power supply switch is not
set at ON.
Are operation controlls
adjusted correctly
as specified?
Are horizontal louvers
at up position (in
heating mode)?
Is there any direct sunlight
in the room?
Poor cooling or heating
Poor cooling
Is city power supply normal?
Is air filter too dirty?
Any doors or windows left
open?
If there are unexpected heat
sources in the room?
Are there any obstacles at inlet
or outlet grill?
Too many people in the room?
Is leakage current breaker
activated?
This is very dangerous, please
disconnect power supply
immediately and contact your
dealer
.
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.
Power
failure?
If the fuse on PC board is broken please change it with the type of T.3.15A/250V.

Energy saving
Keep proper room temp.
Too cold or too warm is no good to
your health, and power consumption
will be increased as well.
Air filter should be periodically cleaned
If air filter is clogged:
It will cause poor cooling and
heating ef
ficiency, higher power
consumption and even problem may
occur. In cooling operation,water will
flow out.
Use Timer effectively
You may use Timer mode to keep a
comfortable room temp.when you
wake up or come home from outside.
Avoid direct sunlight
and air flow
Adjust air flow
properly
proper room
temp.

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.
Delivery
Facing up
Do not install the air conditioner on the non-special metal bracket (e.g. theft
guarding net).
If outdoor unit is street installed, it cannot be lower than 2.5m
Use expansion bolt (M10) to fix the outdoor unit installation bracket on the wall.

4.Purging method
Discharge the air out of the indoor unit and the refrigerant pipe by vacuumizing
5.Extra charging amount of the refrigerant
o
(1) Remove the valve cap of 2-way valve of outdoor unit.
(2) Loosen the flare nut connecting to 3-way valve thick pipe 1~1.5 circuit.
(3) Use spanner (hexagon spanner) to loosen 2-way valve core 90
. About 15 seconds later, tighten
2-way valve. The air will discharge out from the flare of thick pipe. When there is no air
discharge, tighten the flare nut according to the specified torque.
(4) Open 2-way valve and 3-way valve.
(5) Tighten the valve cap of the two valves.
(6) Use leakage detector or soap water to check whether there is leakage.
According to the Figure shown method, remove the air in indoor unit and connecting pipe.
Note:
When lengthen the connecting pipe, firstly use non-system Freon R22 to remove the air in the
connecting pipe, then use the above air dischar
ging method to remove the excessive refrigerant.
The newly released air conditioner has been charged extra 80g R22 on the base of the
previously specified refrigerant amount.
This method is only for the first-time installation to remove the air in connecting pipe and
indoor unit.

Electric wiring
2.The wiring method of straight terminal
For those connection wires whose end are not orbicular terminals, their
wiring method is:
Loosen the connecting screw, insert the end of the wire directly into the terminal
block, and then tighten screw. Pull the wire outwards slightly to confirm it is held
tightly.
3.Pressing method of connection wire:
After wiring, the connection wire must be
pressed with wire holding clamp. The wire
holding clamp should press on the out co ver of the connection wire. As the right fi gure shown:
Wiring method
1.The wiring method of orbicular terminal
For the connection wire which end is orbicular
terminal, its wiring method is as the right figure
shown. Dismantle the screw and put it through
the ring at the end of the connection wire, then
connect it to the terminal block and tighten the
screw.

Other instruction and test run
Other instruction
1.Power supply
The air conditioner must use a special power circuit and special air switch.
The air switch should be all-pole switch,and the distance between its two
contacts should be no less 3mm.
The users should provide special switch, grounding wire by themselves.
The wiring should be done by a qualified electrician according to the wir ing rules specified by national standard
An creepage breaker should be installed.
The grounding wire and null wire of receptacle should be strictly separated.
It is incorrect to connect the null wire with grounding wire.
The connection method of power cord is Y connection. If the power cable
is damaged,in order to avoid danger, it must be replaced by the manufacturer
or its specified repair center of the same qualified worker.
All the wires should be copper core wires.
2. Cut and flaring method
Use pipe cutter to cut the pipe,
the burrs must be removed.
After inserting the flarer, perform
flared nut.
