The correct installation is most important to ensure optimum utilities, to improve the
reliability, economic and reduce the frequency of failure. The principle of the manual is to
provide technical instruction on top – installed air conditioner assembly for the technicians
before and after sales services. Read and follow the instruction mentioned in the user
manual carefully. Moreover, it also provides the installation guideline on matching air
conditioner manufacturers.

1. Safety Precaution

1). Wear working suit, working shoes when making operation. Do not wear slippers,
short pants or waistcoat when installing the equipment.

2). Wear goggle or safety glasses preventing the dust or chips falling into the eyes
when looking up.

3). Do not damage van body and the surface of the air conditioner. Clean the carriage
after installation.

4). Pay more attention to the position of oil tank when welding. Do not work near oil
tank.

5). Check the isolation of the cable connection when connecting to 220V power supply.

6). The refrigerant will produce poisonous gases when there is bright fire. The
personnel will suffocate or die when breathing the poisonous gases. The spray of
the refrigerant will hurt the body. The protection is the most important before
installation. Take the following methods if the refrigerant splashing into the eyes or
on the skin: ① Wash eyes or damaged skin with lots of water (do not rub the eyes or
skin); ② Apply the Vaseline on the skin; ③ Go to the hospital immediately for special
treatment;

7). Must not cooling operation when closing the exhaust valve of the compressor,
preventing the damages on personnel and machine because of the higher
pressure.

8). Shut off the power supply when making repair, preventing the fireworks due to short
circuit.

9). Must be carefully, if it’s necessary to drill holes on the van. These holes might
reduce the construction strength. Or result electric shock and fireworks when the
holes drilled on the wire.

10). Keep your hands far away from rotating parts, such as fan when the equipment is
running.

2. Technical preparation before installation

1). Positioning the air conditioner

K36A air conditioner assembly should be installed on the top of the van. The air
return will be absorbed from the bottom to the top and the vented air will be
discharged form the top to the interior of van.

2). Van body isolation

The top van, surrounding, air channel and ventilator must be isolated correctly,
comply with the testing requirement of JT/T216-95 issued by transportation
department. Check the following items: ① the isolation thickness of the surrounding
and top of van body and engine should be higher than ≥30mm; ② The joints between
body, top van and air channel should be isolated, avoiding the loss of refrigeration; ③
Ensure the seal good performance of door and windows of the van; ④ The installation
of all parts should be far from the heat source and ensure to easily repair and
maintenance.

3. Guarantee

The guarantee will be ensured with our guideline and instruction.

We will not take the responsibility about wrong use the unit or
our purchasing pieces such as filters, and general maintenance, control debug trans

portation for the damage is excluded. The warranty is the
only one, other companies or individuals not authorized to provide other warranty. W

arranty is the only beneficiaries of the products purchased, or after the transfer of
property rights of any person or related products and the other people.

1). Warranty period of maintenance must be specified by the
manufacturer to carry out the repairs.

2). Goods sent to the maintenance station is the responsibility of
customers. Manufacturers are not any maintenance of travel or responsible for the t

ransport costs.

The warranty card must be filled out completely and send back to manufacturer for
registration. See the Appendix 1 attached.

4. Assembly Selection

1). Selection:
K36A is suitable installed on trailing car or van. In order to
determine the suitability of the warranty and guarantee consistently effective when in

stalled in commercial vehicles and industrial vehicles, must be approved by the com
pany's technology department approved.

2). Heating (cooling) capacity:

The capability of heating and cooling of the van depends on:

 The dimension of the van
 The thickness of the wall and isolation
 The size of the van windows and types

The recommend length of K36A is 6 meters, with enough wall thickness and isolation
layer no less than 25mm (foam or wool). The windows must have anti-explosion film or
curtain.

Use the best isolation material and double layer windows since the van is

working under high temperature(40ºC), ensure the best refrigeration. The total length

will not be longer than 5 meters.

5. Installation Assembly

1). Roof strength

There must be enough strength since the K36A air conditioner assembly is about
45kg，The top strength of normal car is not enough except the special vehicles with air
conditioning required.

2). Unit positioning

Figure 1

The figure1 describes the installation position of the air conditioner on van roof and
ceiling.

1. Install the unit on the front part of the top van，ensure the unit exhaust in outdoor
un-effect.

2. Do not install the unit at the place where affecting the air return or exhaust. Since it will
affects the uniform of the temperature of inside van.

3. The location should be open to the centerline as the unit base, see
figure 2 and figure 3.
