Safety
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 re.
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 rmly, 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 re.
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 ammable 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.

Safety
CAUTION
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 are at proper torque. Excessive torque may cause ared
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 ared pipe dimension is also changed. Please use R-410A specied
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 uorescent lamp. The farther the better.

Air-conditioner can't be
installed in the place with
inflammable gas. Or it
will cause re hazard.
The unit should be
installed at the place
where the cold/hot air or
noise will not interfere
the neighbours.
Note:
1. In snowy area, install the unit under the bracket or the snow-proof cover against the accumulative
snow on the unit.
2. Do not install the unit at the place where the ammable gas will leak.
3. Install the unit at the strong enough place.

direction vertical. Also x the unit with the screw.
6. When opening the electric box cover for maintenance, please x the cover with screw rmly.
In transportation, please don't dismantle the packaging, and move the unit to the installation
location as closely as possible.
If the packaging must be dismantled, hang up the unit with rope against damage.
Don't hang the unit only at two points. When hanging the unit, don't sit on the unit. The unit should
be upright.
When removing the unit with the forklift, put the fork into the special hole at bottom of the unit.
When being hanged, the rope should be 4 pieces of steel cable with over 6mm diameter.
Put the cushion at the contact section between steel cable and the unit against the distortion or
damage.

at the place with good
ventilation. No obstacle at the
air inlet/outlet. And no strong
wind blows the unit.
The unit should be installed at the
strong enough place. Or it will cause
vibration and noise.
The installation space refers
to the latter info.
The place where the water
can ow uently.
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 is better not be installed
at the below places, or it will
cause damage.

Installation procedure
A. Refrigerant pipe connection
Pipe connection method:
Cautions in piping installation:
Pipe material and specs selection
To ensure the efciency, the pipe should be
as short as possible.
Daub the refrigerant oil on the connector
and the are nut.
When bending the pipe, the bending semi-
diameter should be as large as possible
against the pipe being broken or bent.
When connecting the pipe, aim at the
center to thread the nut by hand and tighten
it with the double spanners.
Don't let the impurity such as sand, water
etc into the pipe.
1. When welding the connector with hard solder, charge nitrogen into the pipe against oxidation.
Or the oxygen lm in the pipe will clog the capillary and the expansion valve, even cause the
death accident.
2. The refrigerant pipe should be clean. If the water and the other impurity enter the pipe, charge
the nitrogen to clean the pipe. The nitrogen should ow under the pressure of about 0.5Mpa
and when charging the nitrogen, stop up the end of the pipe by hand to enhance the pressure
in the pipe, then loose the hand (meanwhile stop up the other end).
3. The piping installation should be executed after the stop valves are closed.
4. Before welding the valve and the pipes, use the wet cloth to cool down the valve and the
pipes.
5. When the connection pipe and the branch pipe need to be cut down, please use the special
shears and cannot use the saw.
1. Please select the refrigerant pipe of the below material.
Material: the phosphoric oxidize seamless copper pipe, model: C1220T-1/2H (diameter is
over 19.05); C1220T-0(diameter is below 15.88).
2. Thickness and specs:
Conrm the pipe thickness and specs according to the pipe selection method(the unit is with
R410A, if the pipe over 19.05 is 0-type, the pressure preservation will be bad, thus it must be
1/2H type and over the min. thickness.
3. The branch pipe must be from JCI.
4. When installing the stop valve, refer to the relative operation instruction.
5. The pipe installation should be in the allowable range.
6. The installation of branch pipe and gather pipe should be performed according to the
relative manual.
When fastening and loosing the
nut, operate with double spanners,
because only one spanner cannot
execute rmly.
If threading the nut as not aiming
at the center, the screw thread will
be damaged, further it will cause
leakage.
