Safety
WARNING
• This manual should always be accessible and close to this air condition equipment.
• There are two types of indications, " WARNING" and " CAUTION". The indication preventing
from death or heavy injury is listed as " WARNING". Even the indication listed as
" CAUTION" may also cause serious accident. Both of them are related to safety, and should
be strictly followed.
• After installation and start-up commissioning, please handover the manual to the user. The
manual should be well kept in safe place and close to the unit.
• The installation or the maintenance should be performed by an authorized agency. The wrong
operation of this air condition equipment may cause water leakage, electric shock or fire.
• Please install the unit on the top of a solid foundation or structure which is strong enough to
support the unit.
• The installation of this air condition equipment should follow local construction codes.
• Use the right cable size, secure the terminal firmly, organize the cables well and make sure no
tension is added on cables. Cable insulation should not be damaged. The incorrect installation
may lead to overheat or fire.
• When installing or moving the unit, the refrigerant system should be vacuumed and recharged
with R-410A refrigerant. If any other gas enters the system, it may lead to abnormal high
pressure which may cause damage or injury.
• Please use the proper manifolds or branches during the system installation. The wrong parts
may cause refrigerant leakage.
• Keep the drain pipe away from toxic gas vents to prevent possible pollution of indoor
environment.
• During or after the installation, please check whether there is refrigerant leakage. If any
leakage, please take any measures for ventilation. The refrigerant may be toxic at some
concentration levels.
• The unit is not explosion-proof. Please keep it away from flammable gases.
• The drain pipe should be installed per this manual to ensure proper drainage. The pipe should
be well insulated to avoid condensation. Wrong installation may lead to water leakage.
• Both liquid pipe and the gas pipe should be also well insulated. Not enough insulation may
lead to system performance deterioration or humidity formation.
• This air condition equipment is not intended to be operated by persons with lack of experience
and training, unless they have supervision or instruction concerning use of this air condition
equipment.
• Please keep children away from this air condition equipment.

• Grounding wire should be connected with the grounding bar. The grounding wire can not
be connected to the gas pipe, water pipe, lightening rod or the telephone grounding wire.
Improper grounding may cause electric shock.
• Units installed on roof should have appropriate access and handrail.
• Use the wrench to fasten the nut and flare at proper torque. Excessive torque may cause
flared section to broke leading to refrigerant leakage.
• After refrigerant pipe installation, please take nitrogen leakage test to avoid refrigerant
leakage.
• R-410A is the only permitted refrigerant.
• To avoid mischarging wrong refrigerant, the check valve diameter is changed for R-410A. To
strengthen the pipe, the flared pipe dimension is also changed. Please use R-410A specified
tools as shown below.
• When charging refrigerant, the refrigerant must be in liquid state from the tank.
• To prevent EMC interference on other appliances, please keep indoor unit, outdoor unit, power
cable and connecting wire at least 1m away from those appliances .
• Fluorescent lamp (reverse phase or rapid start type) may interfere the remote controller's
signal. Please install indoor unit away from fluorescent lamp. The farther the better.

Installation instruction
For installation, please review the items below:
• Is the connected units quantity and the total capacity in the allowable range?
• Is the refrigerant pipe length in the limited range?
• Is the pipe size proper? And if the pipe installed horizontally?
• Is the branch pipe installed horizontally or vertically?
• Is the additional refrigerant counted correctly and weighed by the standard balance?
• Is there refrigerant leakage?
• Is all the indoor power supplies can be on/off simultaneously?
• Is the power voltage in compliance with the data marked on the rating label?
• Is the address of indoors has been set?
(1) Before installation
1) Before installation, check if the model, power supply, pipe, wires and parts purchased
respectively are correct.
2) Check if the indoors and outdoors can be combined as the following.

(2) Installation place selection
Air-conditioner can't be
installed in the place with
inflammable gas. Or it will
cause fire hazard.
The unit should be installed
at the place with good
ventilation. No obstacle at
the air inlet/outlet. And no
strong wind blows the unit.
The installation space refers
to the latter info.
The unit should be installed at
the strong enough place. Or it will
cause vibration and noise.
• The unit is better not be
installed at the below places, or
it will cause damage.
• The place where there is
corrosive gas (spa area etc).
• The place blowing salty air
(seaside etc).
•Exsits the strong coal smoke.
• The place with high humidity.
• The place where there is device
emitting Hertzian waves.
• The place where voltage
changes greatly.
• The place where the water
can flow fluently.
• The place where no other
heat source will affect the
unit.
• Pay attention to the snow
against clogging the
outdoor.
• In installation, install
the anti-vibration rubber
between the unit and the
bracket.
The unit should be
