Safety Principles for Installing Air Conditioner

Requirements For Installation Position

•  Fire prevention device shall be prepared before installation.
•  Keep installing site ventilated.(open the door and window)
•  Ignition source,smoking and calling is not allowed to exist in area where R32 refrigerant rocated.
•  Anti-static precautions in necessary for installing air conditioner, e.g. wear pure cotton clothes and gloves.
•  Keep leak detector in working state during the installation.
•  If R32 refrigerant leakage occurs during tfle installation, you shall immediately detect the concentration in indoor

environment until it reaches a safe level. If refrigerant leakage affects the performance of the air conditioner,
please immediately stop the operation, and the air conditioner must be vacuumed firstly and be returned to the
maintenance station for processing.

• Keep electric appliance, power switch, plug, socket, high temperature heat source and high static away from the

area underneath sidelines of the indoor unit.

• The air conditioner shall be installed in an accessible location to installation and maintenance, without obstacles

that may block air inlets or outlets of indoor/outdoor units, and shall keep away from heat source inflammable or
explosive conditions.

• When installing or repairing the air conditioner and the connecting line is not long enough, the entire

connecting line shall be replaced with the connecting line of the original specification; extension is not allowed.

• Use new connection pipe, unless re-flaring the pipe.

•  Avoid places of inflammable or explosive gas leakage or where there are strongly aggressive gases.
•  Avoid places subject to strong artificial electric/magnetic fields.
•  Avoid places subject to noise and resonance.
•  Avoid severe natural conditions (e.g. heavy lampblack, strong sandy wind, direct sunshine or h1gli temperature

heat sources).

•  Avoid places within the reach of cnildren.
•  Shorten the connection between the indoor and outdoor units.
•  Select where it is easy to perform service and repair and where the ventilation good.
•  The outdoor unit shalrnot be installed in any way that could occupy an aisle, stairway, exit, fire escape, catwalk or

any other public area.

• The outdoor unit shall be installed as far as possible from the doors and windows of the neighbors as well as the

green plants.

Installation environment inspection

• Check nameRlate of outdoor unit to make sure whether the refrigerant is R32.
• Check the floor space of the room. The space shall not be less than usable space(sm2 ) in the specification.The

outdoor unit shall be installed at a well-ventilated place.

• Check the surrounding environment of installation site: R32 shall not be installed in the enclosed reserved space

of a building.

• When using electric drill to make holes in the wall, check first whether there is pre-buried pipeline for water,

electricity and gas.

• It is suggested to use the reserved hole in the roof of tfle walr

Requirements of the mounting structure

• The mounting rack must meet the relevant national or industrial standards in terms of strength with welding and

connection areas rustproofed.

• The mounting rack and its load carry surface shall be able to withstand 4 times or above the weight of the unit,

or 200kg, whichever is heavier.

• The mounting rack of the outdoor unit shall be fastened with expansion bolt.
• Ensure the secure installation regardless of what type of wall on which it is installed, to prevent potential

dropping that could hurt people.
