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.

WARNING

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.

Installation instruction

(3) Installation place selection

(4) Transportation

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.

4. Install the unit at the at place.

5. When being installed at the place with strong wind, set the air outlet of the unit and the wind

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.

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 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.
