Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTION! In orre t operations may result in injuries or ma hine damages; in some ases may
ause serious onsequen es.
In orre t operations may result in severe onsequen es of death or serious injuries.
INSTRUCTIONS: These information an ensure the orre t operation of the ma hine.
Be sure to onform with the following important Safety Cautions.
The S fety C utions should be t h nd so th t they c n be checked t ny time when needed.
If the onditioner is transferred to the new user, this manual should be as well transferred to the
new user.
S fety C utions
C refully re d the following inform tion in order to oper te the irconditioner
correctly.
WARNING!
If ny bnorm l phenomen is found
(e. g.smell of firing), ple se cut off the
power supply immedi tely, nd cont ct
the de ler to find out the h ndling
method.
Don't dism ntle the outlet of the
outdoor unit.
The exposure of fan is very dangerous
whi hmay harm human beings.

In su h ase, to ontinue using the
onditioner will damage the onditioner,
and may ause ele tri al sho k or fire
hazard.
In orre t maintenan e and repairment
may ause water leak, ele tri al sho k
and fire hazard.
When need m inten nce nd rep irment,
c ll de ler to h ndle it.
After long time use of ir-conditioner
the b se should be checked for ny
d m ges.
If the damaged base is not repaired, the
unit may fall down and ause a idents.

If onditioner is installed in a small
room be sure to take every measure in
order to prevent suffo ation a ident
even in ase of refrigerant leakage.
When conditioner is deinst lled or
reinst lledde ler should be respon-
sible for them.
In orre t installation may ause water
leaking, ele tri al sho k and fire hazard.
No goods or nobody is permitted to
pl ced on or st nd on outdoor unit.
The falling of goods and people may
ause a idents.
Don't oper te the ir-conditioner with
d mp h nds.
Otherwise will be sho ked.
Only use correctly-typed fuse.
May not use wire or any other materials
repla ing fuse, other-wise may ause
faults or fire a idents.

Note :
(1). Fix the parts with s rews
(2).Don't intake the strong wind dire tly to the
outlet air-flow hole.
(3).A one meter distan e should be kept from the
unit top
(4).Don't blo k the surroundings of the unit with
sundries
Inst ll tion Procedure
2. Selection of the pl ce of inst ll tion
1. Accessories
"Edging" for prote tion of ele tri wires from an
opening edge.
Sele t the pla e of installation satisfying the following onditions and, at the
same time, obtain a onsent from the lient or user.
Edging
Pla e where air ir ulates.
Pla e free from heat radiation from other heat sour es.
Pla e where drain water may be dis harged.
Pla e where noise and hot air may not disturb the neighborhood.
Pla e where there is not heavy snowfall in the winter time.
Pla e where obsta les do not exist near the air inlet and air outlet .
Pla e where the air outlet may not be exposed to a strong wind.
Pla e surrounded at four sides are not suitable for installation. A 1m or more
of overhead spa e is needed for the unit.
Mount guide-louvers to pla e where short- ir uit is a possibility.
When installing several units, se ure suffi ient su tion spa e to avoid short
ir uiting.
Wind dire tion
NO
(2) Inst ll tion where the re with strong winds.
Install the unit so that the air outlet se tion of the unit must NOT be fa ed
toward wind dire tion.
(1) Open sp ce requirement round the unit

(2) Piping size
Install the removed flare nuts to
the pipes to be onne ted, then
flare the pipes.
(3) Limit tions for one w y piping length nd vertic l height difference.
Pre autions for refrigerant piping
Do not twist or rush 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.
Che k flare- onne ted area for gas leakage.
Conne ting 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 rush
the pipe.
When onne ting pipe, hold the pipe entre to entre then
s rew nut on by hand, refer to Fig.
Be areful not to let foreign matters, su h as sands enter
the pipe.
(4) Piping connection
For ed fastening without entering
may damage the threads and ause a
gas leakage.

In the first to third test steps, if the pressure drops, he k the leakage in ea h joint
use sense of hearing, feeling and soap water, et . methods to find the leaking point.
After onfirming the leaking point, welding it again or tighten the nut tightly again.
Che king the leaking point
First step: 0.3MPa (3.

over 3 minutes.
Se ond step: 1.5Mpa
(15kg/ m

g) pressurize
over 3 minutes. Large
leakage will be found.
Third step: 3.0 MPa
(30kg/ m
2
g) pressurize
about 24 hours. Little
leakage will be found.
After finishing onne tion of refrigerant pipe, it shall perform air tightness test.
The air tightness test adopts nitrogen tank to give pressure a ording to the pipe onne tion
mode as the following figure shown.
The gas and liquid valve are all in lose state. In order to prevent the nitrogen entering the
ir ulation system of outdoor unit, tighten the valve rod before giving pressure (both gas
and liquid valve rods).
