Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may
cause serious consequences.
Incorrect operations may result in severe consequences of death or serious injuries.
INSTRUCTIONS: These information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The Safety Cautions should be at hand so that they can be checked at any time when needed.
If the conditioner is transferred to the new user, this manual should be as well transferred to the
new user.
Safety Cautions
Carefully read the following information in order to operate the airconditioner
correctly.
WARNING!
If any abnormal phenomena is found
(e. g.smell of firing), please cut off the
power supply immediately, and contact
the dealer to find out the handling
method.
Don't dismantle the outlet of the
outdoor unit.
The exposure of fan is very dangerous
whichmay harm human beings.
switch
off
In such case, to continue using the
conditioner will damage the conditioner,
and may cause electrical shock or fire
hazard.
Incorrect maintenance and repairment
may cause water leak, electrical shock
and fire hazard.
When need maintenance and repairment,
call dealer to handle it.
After a long time use of air-conditioner
the base should be checked for any
damages.
If the damaged base is not repaired, the
unit may fall down and cause accidents.
2

Air-conditioner can't be installed in
the environment with inflammable
gases because the inflammable gases
near to air-conditioner may cause fire
hazard.
Connect earthing wire.
Use discharge pipe correctly to ensure
efficient discharge.
Earthing wire should not be con-
nected to the gas pipe, water pipe,
lightning rod or phone line, in-
correct earthing may cause shock.
Incorrect pipe use may cause water
leaking.
Earthing
Safety Cautions
WARNING!
Installed electrical-leaking circuit
breaker.
It easily cause electrical shock without
circuit breaker.
Please let the dealer be responsible for
installing the conditioner.
Incorrect installation may cause water
leak, electrical shock and fire hazard.
Call the dealer to take measures to
prevent the refrigerant from leaking.
If conditioner is installed in a small
room be sure to take every measure in
order to prevent suffocation accident
even in case of refrigerant leakage.
When conditioner is deinstalled or
reinstalleddealer should be respon-
sible for them.
Incorrect installation may cause water
leaking, electrical shock and fire hazard.
No goods or nobody is permitted to
placed on or stand on outdoor unit.
The falling of goods and people may
cause accidents.
Don't operate the air-conditioner with
damp hands.
Otherwise will be shocked.
Only use correctly-typed fuse.
May not use wire or any other materials
replacing fuse, other-wise may cause
faults or fire accidents.

Note :
(1). Fix the parts with screws
(2).Don't intake the strong wind directly to the
outlet air-flow hole.
(3).A one meter distance should be kept from the
unit top
(4).Don't block the surroundings of the unit with
sundries
Installation Procedure
2. Selection of the place of installation
1. Accessories
"Edging" for protection of electric wires from an
opening edge.
Select the place of installation satisfying the following conditions and, at the
same time, obtain a consent from the client or user.
Edging
Place where air circulates.
Place free from heat radiation from other heat sources.
Place where drain water may be discharged.
Place where noise and hot air may not disturb the neighborhood.
Place where there is not heavy snowfall in the winter time.
Place where obstacles do not exist near the air inlet and air outlet .
Place where the air outlet may not be exposed to a strong wind.
Place surrounded at four sides are not suitable for installation. A 1m or more
of overhead space is needed for the unit.
Mount guide-louvers to place where short-circuit is a possibility.
When installing several units, secure sufficient suction space to avoid short
circuiting.
Wind direction
NO
(2) Installation where the area with strong winds.
Install the unit so that the air outlet section of the unit must NOT be faced
toward wind direction.

3. Installation of outdoor unit
Fix the unit in a proper way according to the condition of a place where it is
installed by referring to the following .
(1) Installation
Install the unit so that the angle of inclination must be less than 3 degrees.
Note: (1) Give enough room for the concrete
foundation to fix by anchor bolts. Note: (1) Place the concrete foundation deep enough.

Precautions for refrigerant piping
Do not twist or crush piping.
Be sure that no dust is mixed in piping.
Bend piping with as wide angle as possible.
Keep insulating both gas and liquid piping.
Check flare-connected area for gas leakage.
Connecting method (indoor unit)
Apply refrigerant oil at half union as large and flare nut.
To bend a pipe, give the roundness as possible not to crush
the pipe.
When connecting pipe, hold the pipe centre to centre then
screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands enter
the pipe.
(4) Piping connection
Forced fastening without centering
may damage the threads and cause a
gas leakage.

In the first to third test steps, if the pressure drops, check the leakage in each joint
use sense of hearing, feeling and soap water, etc. methods to find the leaking point.
After confirming the leaking point, welding it again or tighten the nut tightly again.
Checking the leaking point
First step: 0.3MPa (3.
0kg/cm2g) pressurize
over 3 minutes.
Second step: 1.5Mpa
(15kg/cm2g) pressurize
over 3 minutes. Large
leakage will be found.
Third step: 3.0 MPa
(30kg/cm2g) pressurize
about 24 hours. Little
leakage will be found.
After finishing connection of refrigerant pipe, it shall perform air tightness test.
The air tightness test adopts nitrogen tank to give pressure according to the pipe connection
mode as the following figure shown.
The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the
circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas
and liquid valve rods).

From pressurizing to 24 hours later, each 1* difference of ambient temperature
will make 0.01MPa(0.1kg/cm2g) pressure change. It shall be corrected during test.
Check if the pressure drops
The pressure does not drop-passed
The pressure drops-check the leaking point.
