The following four important points of safety and suggestions should be paid great attention:
Comply with the following important points of safety.
Put these important points of attention and suggestions nearby and convenient for reference in need.
Hand over this instruction manual to new user if you resell this machine.
Entrusted Installation
Installation of the machine should be
entrusted to certified person of after
service. Unauthorized installation may
cause water leakage, electric shock or
fire hazard for improper operation.
To prevent leakage of refrigerant, let
certified person of after service do it.
Leakage of refrigerant over certain
consistence may result in shortage of
oxygen. Enough precautions MUST be
done to avoid oxygen shortage in case
of refrigerant leaking if the room where
the air-conditioner is installed is small.
The power supply must be fitted with
earth line to ensure valid earthing of
the air-conditioner. No or incomplete
earthing connection may cause the risk
of electric shock.
Warning
Warning for installation

Warning for use Warning for move and repair
Avoid your body being blown directly by
cold wind for long period, otherwise your
health may be affected.
When you have to disassemble and reinstall
the machine, entrust it to after service.
Improper installation may cause fire hazard,
electric shock or damage of machine.
If something abnormal (e.g.: burnt smell
etc.) occurs, stop running the machine, shut
down the manual power switch and contact
after service. Continuous operation in
disorder may cause fire hazard or electric
shock etc.
Unauthorized alteration or repair work is
strictly forbidden. Improper alteration or
maintenance may cause fire hazard, electric
shock or water leakage. Repair work should
be entrusted to certified person of after
service.
Attention points for installation
Ensure the drainage hose work normally
during installation.
Improper installation of drainage can cause
water leakage and damp articles.
Ensure electric leakage breaker being
installed. Electric leakage breaker MUST
be installed, otherwise electric shock may
be caused.
DO NOT install the machine in place where
flammable gas releases easily to avoid fire
hazard.
If the power supply cord is damaged, call
a certified electrician of the manufacturer
or other maintenance department to replace
it.

Attention points for use
DON'T lay any burning facilities in place
where winds produced by the machine can
reach. Incomplete combustion of burning
facility may be caused otherwise.
Ensure ventilation of the room if the
machine is used with burning facilities.
Deficient ventilation can cause oxygen
shortage.
DON'T clean the machine with water.
Electric shock may occur otherwise.
Check whether installation bench of the
machine is damaged after a long period
of use. Machine on damaged bench may
fall down and cause human injury or
other damage.

Electric shock may occur otherwise.
Stop operation and shut down manual
power switch before cleaning and
maintenance.
The machine CANNOT be used for the
purpose of preserving food, animals,
plants, precision instruments and artwork
etc., which may be destroyed otherwise.
The power supply MUST be of rated
voltage and connected with special
electrical supply circuit.
DON'T replace fuse with material other
than fuse of proper capacity. Replacing
fuse with metal wire or copper etc. can
cause fire hazard or other faults.
DON'T put flammable spray articles nearby
or spray them to the machine. Fire hazard
may occur otherwise.

Attention

Check whether earthing wire is broken or falls off.
Check whether air filter was omitted.
Switch on power supply of the outdoor unit 12 hours in priority to entrust.
During heating program, the machine adopts heat pump mode to release heat indoors with that absorbed from outdoors.
Therefore its heating ability reduces when outdoor temperature descends.
Heat ability
During heat operation, if the outdoor unit is adhered with frosts, the machine will automatically turn to frost-
removing operation which lasts about 2~10 minutes.
During frost-removing operation, fan of indoor unit runs at low speed or stops while outdoor unit stops.
To protect the machine, for immediate restart after a stop, the compressor does not run until after a interval of 3 minutes.
All operations will stop when there is a power failure during the machineís running.
Running indicator on remote controller flashes when the system is reenergized after power failure.
Before restart, press on/off button of the remote controller.
Note: If you have set power down memory function, the machine will get back to the status before power failure when it is
reenergized.
Confirmation before running
Removal of frost in heat operation
3 minutes protection
Power failure
Protection setting (High pressure switch)
If something abnormal happens with the machine, the protection setting will act to stop running automatically. Press
ì checkî button on the remote controller to see failure code shown.
Protection setting acts in the following case.
During cool operation
Inlet or outlet of outdoor unit is blocked.
Strong wind continuously blows into the outlet of outdoor unit.
During heat operation
Large amount of dust adheres on air filter screen of indoor unit.
Outlet of indoor unit is blocked.
Air filer of cassette type
Air filter screen must be installed near the inlet when installing air-conditioner of flush type.After trial run
of the machine, verify the following items:
Position where air filter screen is installed How to disassemble the filter How to clean the filter
Operation of fans of units that stop
To protect units that stop during running of other indoor unit, run their fans for 2~8
minutes at an interval of 30 or 60 minutes.
Note:
Confirm failure code shown on the remote controller, shut down power switch and find out reasons after
protection setting works. (check method as seen from " check" on page 21). Continuous operation without
solving problems can cause faults of the machine.
Ensure air filter is installed. Without the filter, dust may accumulate on heat exchanger and cause water
leakage.
Each indoor unit can run individually or many indoor unit run in meantime. However, heat and cool operation
cannot be run at the same time.

Donít
disconnect!
Turn on power supply of the outdoor
unit 12 hours in priority to running.
Switch on in priority
to running
Air quarding plate MUST be used
distinctively
In cool operation, wind outlet or surface of air
guarding plate may have moisture condensation
if the air-conditioner always drafts air downward
for a long period.(for cassette type)
Cool and heat operation cannot run at
the same time
For protection of outdoor unit, after long period
of shutdown, power of outdoor unit MUST be
switched on 12 hours in priority to running.
Donít disconnect the manual power switch during
usage of remote controller, operate with on/off
button on the controller.
All indoor subassembly cannot run heat and cool
operation at the same time and should be operated
with the same mode. (fan mode is an exception)
In heat operation, heat air may gather below the
ceiling and reduce heating effect if the air-
conditioner always drafts air upward for a long
period.
Apart from TV and radio receiver
Keep air-conditioner and its remote controller at
least 1 meter away from TV and radio receiver to
avoid unstable image on TV or noise in radio.
