The refrigerants used for air conditioners are environmentally friendly hydrocarbons R32. This kind of erant is
combustible and odorless. Moreover, it can burn and explode under certain condition. However, there will be no
risk of burning and explosion if you comply with the following table to install your air conditioner in a room with
an appropriate area and use it correctly.
Compared with ordinary refrigerants, Refrigerant R32 is environmentally friendly and do not destroy the ozone
sphere and that its value of greenhouse effect is also very low.

A storm window frame will not allow the air conditioner to tilt properly which in turn will keep it from draining
properly. To adjust for this, attach a board or piece of wood to the sill. The board or wood piece should have
a depth of at least 1/2”. Make sure the board or piece of wood is approximately 1/2” higher than the storm
window frame. This will allow the air conditioner to tilt enough for proper drainage.

THROUGH-THE-WALL INSTALLATION INSTRUCTIONS - OPTIONAL
The case may be installed through-the-walll as optional.
Read completely, then follow step-by-step.
NOTE: Obtain all materials locally for mounting the air
conditioner through-the-wall.
Through-the-wall installation is not appropriate, if any of
the side or top louvers of case is obstructed by the wall.
All side and top louvers in the case must project on the
outdoor side of the wall.
The room side of the case must project into the room far
enough to maximize the balance of the unit.
The case must be installed level from side to side and
with a slight tilt from front to rear. Use a level, no more
than a 1/2 bubble will be correct slant to the outside.
Lintel angle is required to support bricks or blocks
above opening.
Flashing is required and should extend the length of the
opening to ensure no inside cavity leakage occurs.
Building a wooden frame is required when install the case
through-the-wall. The opening and dimension of wooden
frame is required as below.

INSTALLATION & ASSEMBLY INSTRUCTIONS
Important Considerations
12
Before installing the appliance, you must read the manual carefully to get the safety
information and notes.
A leak test must be done after the installation is completed.
It is a must to do the safety inspection before maintaining or repairing an air
conditioner using combustible refrigerant in order to ensure that the fire risk is
reduced to minimum.
It is necessary to operate the machine under a controlled procedure in order to
ensure that any risk arising from the combustible gas or vapor during the operation
is reduced to minimum.
Unit refrigerant charge amount: refer to unit name plate marking.

2. Operation Safety
Open Flames Prohibited Ventilation Necessary
Open Flames Prohibited
Mind Static Electricity Must Wear Protective Clothing and anti-static gloves Don't use mobile phone
3. Installation Safety
Refrigerant Leak Detector
Appropriate Installation Location
The left picture is the schematic diagram of a refrigerant leak detector.
Please note that:
1. The installation site should be in a well-ventilated condition.
2. The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open fire
or welding, smoking, drying oven or any other heat source higher than 548 which easily produces open fire.
3. When installing an air conditioner, it is necessary to take appropriate anti-static measures such as wear
anti-static clothing and/or gloves.
4. It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets of
the indoor and outdoor units should be not surrounded by obstacles or close to any heat source or combustible
and/or explosive environment.
5. If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the refrigerant
leaks completely for 15 minutes. If the product is damaged, it is a must to carry such damaged product back to
the maintenance station and it is prohibited to weld the refrigerant pipe or conduct other operations on the user's
site.
6. It is necessary to choose the place where the inlet and outlet air of the indoor unit is even.
7. It is necessary to avoid the places where there are other electrical products, power switch plugs and sockets,
kitchen cabinet, bed, sofa and other valuables right under the lines on two sides of the indoor unit, and also
prevent mechanical damage from occurring.
