＂Important Safety Information＂ affords very important points about how to
operate the unit safely.To prevent injury to the user or other people and property
damage, the following instructions must be followed. Incorrect operation due to
ignoring of instructions may cause harm or damage.
The safety precautions listed here are divided into two categories. In either
case, important safety information is listed which must be read carefully.
1. Never install the unit by yourself and call the professionals from distributor
or maintenance center for installation, or it may lead to accidents and affect
the performance of usage .
2. Be sure to install leakage protection switch.
If not installation leakage protection switch, may cause the accident of getting
an electric shock etc .
3.The outdoor unit should be installed on the firm level reliably.
4. Must keep the noncongestion that drain off water, otherwise the condensate
will be damaged your furniture, electric devices,etc.
5.Make sure that the air conditioner is grounded unfailingly,or it may cause
an electric shock .

13.Do not touch the rotary air vents with your hands or other objects to avoid of
accidents or damage.
14. It is forbidden placing goods above the machine set, so as not to result in the
danger of the fall off when they are running.
15.
the equipment contains fluorinated greenhouse gas R410A ,the value of
Global Warming Potential(GWP) is 2087.5.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
16.Children should be supervised to ensure that they do not play with the
appliance.
17.If the appliance is fixed wiring, the appliance must be fitted with means for
disconnection from the supply mains having a contact separation in all poles
that provide full disconnection under over voltage category III conditions, and
these means must be incorporated in the fixed wiring in accordance with the

1.2 Use notices
1. The unit must be installed in outdoor field where there is sunlitproof and
rainproof establishments , or else our company is not responsible for the
problems caused because of wrong installation.
2. All the operation parameters of the unit set , the set values of the protective
device have been set before the delivery , the consumers are not allowed to
change the set values at random , and also are not allowed to make the line of
the protective devices of the machine set , short-circuit or the unit may be
damaged as result of improper protection.
3. When the unit is running, the unprofessional personnel do not touch any
electrical element and buttons, or it will result in serious accident.
4. If the unit goes wrong , don't repair it by yourself , please consult the service
center of the company ( the consultation telephone number can refer to the
back over ). If the machine set is repaired by unprofessional personnel , it may
result in the machine breakdown or the casualty of personnel.
5. During cleaning the unit, never clean the operational panel with benzene,
diluent agent , or chemical cloth and so on , or it will result into fade or the fault
function of the buttons ; It is not allowed to directly sprinkle the unit with
water or cleaning agent, when it is necessary, please clean them with a cloth
that is stained with water or neutral cleaning agent.
6. In order to prolong the service time of the air- condition, please do not start the
compressor frequently. (It should not be more than five times in an hour).
7. The refrigerant used in the machine set is noncombustible and innoxious , as
for the specific gravity of which is greater than air , so when it leaks, it will
diffuse on the ground. As a consequence, if the unit is installed in a room, it
must make sure that the ventilation condition is good , or it way result in serious
asphyxia when the refrigerant leaks.
8. If the refrigerant leaks, stop the unit as soon as possible, and get in touch with
the maintenance and repairmen in time, the flame on the field is forbidden,
because if the refrigerant contacts with the flame, it will decompose into
harmful gas
9. Please service the machine set termly according to the requirements of the
specification , in order to make sure that the operation condition of the machine
set is good.

4.2 Preparation before installation
According to the position and installed dimension to made the base.(Fig 3)
4.2.1 Outdoor unit
4.2.1.1 Install the unit on the ground:
■ Concrete foundation
This foundation is cast with the design mark concrete, which has great anti-
vibration effect, the following factors shall be emphasized:
1) The surface of concrete foundation is massy, firm and flat. The bearing of the
support surface is more than 2 times of the unit weight.
2) When the cement foundation platform is made , the following measures are
adopted: put the whorl reinforcing steel bar ( Dia > 9.5 mm )into the concrete
foundation, the whorl reinforcing steel bar must be enlaced as top and bottom
layers, and the space between bars is 10cm.
3) When making the cement foundation on the concrete floor board, please keep
the surface coarse, and then clean and wet it, after all of these works, make
the concrete foundation seat.
4) The mix ratio of the concrete is 1:2:4, if necessary, embed some proper
anchor bolts. Finally, keep the surface of the basic platform smooth.
5) The surface of the concrete foundation platform should have the waterproof
disposal and around of it we should have a drip through and the gradient is
more than 30 ℃, pointing to outfall.
6) Until the concrete foundation is fully dry, you can install the unit.
10

7) In order to run the unit quietly and avoid the noise and vibration interference to
the surroundings, there should keep a separate layer for vibration-proof
between the base of the unit and foundation. And then keep the unit level
when installing.
8) To avoid units distortion and even rupture, which is caused in displacement of
the unit run for a long time, you should take some measures to fix the unit at the
restrict position.(Fig3)

5 2 Install and connect refrigerant pipes
After installing the indoor and outdoor unit, you can connect the pipes.
5.2.1 Inspection of pipes
Before connecting pipes, inspect pipes so that the following requirement is met;
■ The inside of the pipe is clean, no dust, air or water gathers in the pipe;
■ Flares and nuts at both ends of the pipe are in good condition.
Bend the refrigerant pipe following the scheduled routine. During bending
pipes, avoid the pipe broken or out of shape and keep the bent radius of the
copper pipe as big as possible (400mm at least) and the bent number no more
than 3 times.
5.2.2 Connection of pipes
As connecting the refrigerant pipes for indoor units, the operation must be
rapid to make sure that the time for connecting two pipes is not too long at site.
5.2.2.1 When connecting the flared connector ,keep two pipes aligned with the
same center and then put on the screw nut and revolved them in. Finally , tighten
the screws with wrenches ,refer to the figure below:
Please fix the copper with wrenches in proper torque force according to
Table 4 Torque Force Table.
