1.5.2 Steady cabinet indoor unit
Powerfull running & long distance air sending
The unit can run powerfully and supply large volume of cooled air to the room. Long distance and
large angle air sending ensures average temperature distribution, bring you much more comfortable
indoor environment in the shortest time.
Newly designed display panel, more simple
On the display panel there are power, operation, timer, and electric heating indicator, from which
you can find the operation state directly, and the indicator flash times can show the failure.
Malfunction Auto-checking
Failure codes displayed by LED or controllers are so detailed for us to find the fail place more
quickly, and can judge the failure content easily.
Powerfull/Soft function
Special button on remoto controller is used to set powerful working or soft working.
Single fan outdoor, more compact
Central control function, if connected with a detector and a central
controller
1.5 Product features
1.5.1 Outdoor unit .
Flexible and easy installation
The outdoor can meet the higher request of installation. From the specifications, you will find for
each unit, how long and how high the piping will be, which will be convenient for design and installation.
Optional safety devices and much more precision control device
a. Ambient temperature sensor,coil temperature sensor and compressor temperature sensor
make the temperature control and defrosting control more precise.
b. High/low pressure switch can feel the discharging pipe pressure and suction pipe pressure on
time and precisely. If the pressure is too low or too high, it will stop the compressor to prevent it
being damaged for the sake of pressure.
c. 3 minutes delay protection for the compressor, the device can protect the compressor from
some damages and make the compressor have a long life.

3. Safety precaution of indoor and outdoor
Carefully read the following information in order to operate the airconditioner correctly.
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.
IN TRUCTION : These information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The afety 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.
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.

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
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 responsible
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.

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.

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

It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air
discharging (over 40l/min).
The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours.
When vacuumizing, it shall be confirmed both gas and liquid side valves are closed.
If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can be
vacuumized for other 1 hour.
If after hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check
if there is any leaking point and repair the them.
First step: 0. MPa ( .0kg/cm2g) pressurize over minutes.
Second step: 1.5Mpa (15kg/cm2g) pressurize over minutes. Large leakage will
be found.
Third step: .0 MPa ( 0kg/cm2g) pressurize about 24 hours. Little leakage will be
found.
From the first to third steps, if the pressure drops, check the leakage in each joint
by the sense of hearing, feeling or soap water, etc. to find the leaking point.
After confirming the leaking point, welding it again or tighten the nut tightly again.
Checking the leaking point
After pressurizing for 24 hours, each 1 C difference of ambient temperature
will result in 0.01MPa(0.1kg/cm2g) pressure change. It shall be corrected during test.
Check if the pressure drops
If the pressure does not drop, the unit is passed
If the pressure drops, please check the leaking point.
Use vacuum pump to perform vacuumizing. It is strictly forbidden to use the
refrigerant to remove the air inside the system.
After air tightness test and discharging all the nitrogen, connect the vacuum pump
as the following figure shown.

If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the VL and VH on the
meter separator and stop vacuumizing. 1 hour later to confirm if the vacuum degree changes. If changes,
it indicates there is leaking point in the system. Check the leaking point and
repair.
After finishing the above vacuumizing, change the vacuum pump into refrigerant pump to charge the
refrigerant.
When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is unnecessary to
charge additional refrigerant.
If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter.
That is: Refrigerant charging amount = (L-5) x M (g)
For the unit with liquid pipe 6. 5mm, M= 0
For the unit with liquid pipe 9.52mm, M=65
Only in COOLING operation can charge the additional refrigerant.
When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle.
Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the additional
refrigerant in liquid condition.
