Read the following " PRECAUTIONS" carefully before installation.
The caution items stated here must be followed because these important contents are related
to safety. The meaning of each indication used is as below.
Incorrect installation due to ignoring of the instruction will cause harm or damage, and the
seriousness is classified by the following indications.
!This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to
properties only.
WARNING
!CAUTION
1. Injury means causing harmed, burned, electrical shocked, but not serious for hospitalization.
2. Damage of property means disrepair of property, material.
Carry out test running to confirm that no abnormality occurs after the installation. Then, expl-
ain to user the operation, care and maintenance as stated in instructions. Please remind the
customer to keep the operating instructions for future reference.
Engage dealer or specialist for installation. If installation done by user is defective, it
will cause water leakage, electrical shock or fire.
Install according to this installation instructions strictly. If installation is defective, it will
cause water leakage, electrical shock or fire.
Use the attached accessories parts and specified parts for installation. Otherwise, it will
cause the set to fall, water leakage, fire or electrical shock.
Install at a strong and firm location which is able to withstand the set's weight. If the stren-
gth is not enough or installation is not properly done, the set will drop and cause injury.
For electrical work, follow the local national wiring standard, regulation and this installa-
tion instructions. An independent circuit and single outlet must be used. If electrical circuit
capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
When carrying out piping connection, take care not to let air or other substances other
than the specified refrigerant go into refrigeration cycle. Otherwise, it will cause lower
capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
Grounding is necessary. It may cause electrical shock if grounding is not perfect.
Do not install the unit at place where leakage of flammable gas may occur. In case gas
leaks and accumulates at surrounding of the unit, it may cause fire.

If the air conditioner runs for a long time in
"COOLING" or "DRY" mode at air relative
humidity higher than 80% (doors or windows
opened),dew may generate and drip near air outlet.
The protective device will trip at
following cases.
Stop the appliance and restart it at once
or change other modes during operation,
you have to wait 3 minutes before restarting.
After switching on the power circuit breaker
and then turn on the air conditioner at once,
you have to wait about 20 seconds.
In case all operations have stopped, you need
Press "ON/OFF" button again to restart it.
Set TIMER once again if it has been canceled.
Defrost
After a long time of operation, the air
conditioner should be inspected for
the following items.
Abnormal heating of the power supply
cord and plug or even a burnt smell.
Abnormal operating noise or vibration.
Water leakage from indoor unit.
Metal cabinet electrified .
Stop using the air conditioner if above
problem happened.
It is advisable that the air conditioner
should be given a detail check-up
after using for five years even if none
of the above happen.
Do not place any obstacles in front
of the outlet of the outdoor unit for
fear it affects operation and increases
the noise level.
2-5 minutes are necessary to preheat the indoor heat exchanger at the beginning of
"HEATING" operation, lest cold air be discharged.
In "HEATING" operation the appliance will defrost automatically. This procedure lasts
2 10 minutes, then returns to "HEATING" mode automatically. During defrosting, indoor
fan stop running and return to heating mode operation automatically when
defrosting has finished.

The drain pipe of indoor unit must have the heat insulation , or it will condense dew, as well as the
connections of the indoor unit.
The declivity of the drain pipe downwards should be over 2/100, and no winding and bending.
The total length of the drain pipe when pulled out traversely shall not exceed 20m , when the
pipe is over long, a prop stand must be installed every 1.5 to 2m to prevent winding.
Refer to the following figures about the installation of the pipes.
Do not impose any pressure on the connection part of the drainage pipe.
PANEL INSTALLATION (SOLD SEPARATELY)
Panel installation should be done after piping and wiring.
Be sure that the indoor unit and ceiling hole installation size is right before installation.
Be sure to seal the connection parts between - and the panel - the

Check whether the drain pipe is unhindered before testing.
1) Stow water from sprue to check.
2) Stow 600cc water with pot or hose from sprue slowly , preventing touching the drain pump motor.
3) After the preparation work , disconnect the water level switch ,power 220-240VAC to of terminal
board, and the drain pump start up immediately.
4) After drain pump run 2 min.,reset the water level pin, and the drain pump motor will stop after

well ventilated.
2. Keep the required distance away from the wall as reqiured on
the previous page when carrying on installation.
3. Pipe length and drop height should comply with the
scope required below.
4. When operating at a special place, for example, a place
of greasy dirt, vulcanization gas or high-salty seashore,
make sure to adopt an effective isolation measure.
5. Avoid installing it on the roadside where there is a risk
of muddy water.
6. Install it where your neighbors would not be annoyed by
operating noise or discharged hot air.
7. Install it on a fixed shelf that is not subject to increasing noise.

Please refer to the following figures to install.
The following figure only shows the assembly relationship of the indoor unit ,outdoor
unit and refrigerant pipes.
NOTE
The throttle subassembly has been installed in the outdoor unit..
Use two spanners to connect the pipe with indoor/outdoor pipes to avoid the copper pipe cracking.
Please pay attention to the connection orientation when connecting.
Use a vacuum pump, to vacuum from the gas side refrigerant adding mouth of the outdoor
unit.
Don t use the refrigerant of the outdoor unit to do the vacuum. (A certain volume of refrigerant
had been added into the outdoor unit in factory.)
Air and moisture remains inside the refrigeration system, may has the following bad effects:
Rise of pressure inside the refrigeration system;
Decrease of cooling (or *heating) effect;
Moisture frozen and blocking the refrigeration system;
Rusting of certain parts of the system
After connecting the indoor and outdoor units , it is necessary to exhaust the air inside the
pipes completely as follows:

(1).Loosen the liquid pipe flare nut and remove the
exhaust nut of 3-way valve.
(2). Connect the outlet nut of the additional freon refrigerant
pot to the exhaust mouth .
(9).Loosen the valve spindle and core to Maximum.

Refrigerant Volume to Be Added
Refrigerant volume to be added is calculated according to outdoor unit installation manual.
Be sure to add refrigerant measuring by a scale.
If the added refrigerant volume is inadequate (too much or insufficient), the compressor
malfunction will be caused. Be sure to calculate the refrigerant volume carefully.
The service man should write down the piping length and the added refrigerant volume
in the nameplate, which is on the electric control box cover of outdoor unit, for
diagnosing the compressor and refrigeration circulation malfunction.
CAUTION
The refrigerant refrigerant charge volume for the unit is based on using a 5m connecting
pipe. If the connecting pipe's length is longer than 5m, it is advisable to charge
additional refrigerant for the unit in order to achieve better operation.

Grounding must be properly done.
Improper connection may cause fire.
Electric Wiring must be done by professionals. Use a separate circuit according
to national regulations.
The grounding wire should be away from gas pipes, water pipes, telephone,
lightening rods or other grounding wires. Improper grounding may cause electric
shock.
If the wiring capacity is not enough, electric shock or fire may occur.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent
or a similarly qualified person in order to avoid a hazard
