● A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
The external switch shall be incorporated to completely disconnect from power supply. It should disconnect all
poles, and a contact separation of at least 3mm must be present.
● Do not install the unit near a location where there is fl ammable gas. The outdoor unit may catch
fi re if fl ammable gas leaks around it.
●
Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist fl ows to the indoor
unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance and may deform
and in the worst case, break the plastic parts of the indoor unit.
● Please ensure smooth fl ow of water when installing the drain hose.
● Piping shall be suitable supported with a maximum spacing of 1m between the supports.

This unit is chargeless up 30m pipe length.
●
Installation of pipe length less than minimum pipe length
requirement (3 meters) may generate an abnormal sound.
CAUTION
● The difference in height
between the indoor and
outdoor unit should be
kept max 20m.
● The connecting pipe,
no matter big or small,
should all be insulated
with insulation pipe and
then wrapped with vinyl
tape. (The insulator will
deteriorate if it is not
wrapped with tape).

drain hose.
Please use insulated drain
hose for the indoor piping
(commercial product).
The indoor piping should be
insulated with the enclosed
insulation pipe. (If the
insulator is insufficient,
please use commercial
products).

BURST HAZARD
Do not allow air, etc. to get
into refrigerant cycle (piping)
RISK OF EXPLOSION
Compressor must be stopped
before removing refrigerant
pipes.
All service valve must be fully
closed after pumping down
operation.
WARNING
● Do not use means to accelerate the defrosting process or to clean, other than those recommended by the
manufacturer. Any unfi t method or using incompatible material may cause product damage, burst and serious
injury.
● The appliance/pipe-work shall be stored in a well ventilated room with indoor fl oor area larger than A
min
[refer
to Table 1] and without any continuously operating ignition source. Keep away from open fl ames, any operating
gas appliances or any operating electric heater. Else, it may explode and cause injury or death.
● The appliance/pipe-work shall be installed, and/or operated in a room with fl oor area larger than A
min
[refer to
Table 1] and keep away from ignition sources, such as heat/spark/open fl ame or hazardous areas such as gas
appliances, gas cooking, reticulated gas supply systems or electric cooking appliances, etc.
● Do not pierce or burn as the appliance/pipe-work is pressurized. Do not expose the appliance/pipe-work to heat,
fl ame, sparks, or other sources of ignition. Else, it may explode and cause injury or death.
WARNING
Refrigerant piping
must be protected
from physical
damage. Install a
plastic cover or
equivalent.

WARNING
!
● The Outdoor unit must be mounted at a location which can support
heavy weight. Otherwise, noise and vibration will increase.
CAUTION
!
● Do not expose the unit under direct sunshine or rain. Besides,
ventilation must be good and clear of obstruction.
● The air blown out of the unit should not point directly to animals
or plants.
● The clearances of the unit from top, left, right and front are
specifi ed in fi gure below. At least 3 of the above sides must be
open air.
● Be sure that the hot air blown out of the unit and noise do not
disturb the neighbourhood.
● Do not install at a location where there is fl ammable gas, steam,
oil and smoke.
● The location must be convenient for water drainage.
● Place the Outdoor unit and its connecting cord at least 1m away
from the antenna or signal line of television, radio or telephone.
This is to avoid noise interference.
● Do not install outdoor unit facing strong wind direction. It may
damage the fan motor.
●
Do not install the outdoor unit in a place where small animals
may build their nests. If small animal goes inside the unit and
touches the electrical parts, failure of the unit, smoke or fi re may
be caused. Request your customer to keep the surrounding of
the unit is clean.

●
Flare nut must use a torque wrench without fail. Tighten with the specifi ed tightening
torque. If the fl are nut is tightened too much, after a long period of time, the fl are nut
breaks, Gas leakage, stagnation, touching fi re, rarely cause ignition.
●
Sharp bending of the pipe use the polyethylene rod, bend not crushed the pipe. Gas
leakage from the crushed part, stagnation, touching fi re, rarely cause ignition.
●
Please request your sales agent or qualifi ed technician to install your unit. Water
leakage, short circuit or fi re may occur if you do the installation work yourself.
●
Please observe the instructions stated in the installation manual during the process of
installation. Improper installation may cause water leakage, electric shock and fi re.
●
A brazed, welded, or mechanical connection shall be made before opening the valves to
permit refrigerant to fl ow between the refrigerating system parts. A vacuum valve shall
be provided to evacuate the interconnecting pipe and/or any uncharged refrigerating
system part.
●
Mechanical connectors used indoors shall comply with ISO 14903. When mechanical
connectors are reused indoors, sealing parts shall be renewed. When fl ared joints are
reused indoors, the fl are part shall be re-fabricated.
●
Refrigerant tubing shall be protected or enclosed to avoid damage.
●
Make sure that the units are mounted at locations which are able to provide full support
to the weight of the units. If not, the units may collapse and impose danger.
●
Observe the rules and regulations of the electrical installation and the methods described
in the installation manual when dealing with the electrical work. Use power cables
approved by the authorities of your country.
●
Be sure to use the specifi ed wire for connecting the indoor and outdoor units. Please
ensure that the connections are tight after the conductors of the wire are inserted into
the terminals. Improper insertion and loose contact may cause over-heating and fi re.
●
Please use the specifi ed components for installation work. Otherwise, the units may
collapse or water leakage, electric shock and fi re may occur.
●
Be sure to use the specifi ed piping set for R32. Otherwise, this may result in broken
copper pipes or faults.
●
When installing or removing an air conditioner, only specifi ed refrigerant (R32) shall be
allowed, do not allow air or moisture to remain in the refrigeration cycle. Otherwise,
pressure in the refrigeration cycle may become abnormally high so that a rupture may
be caused.
●
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas
comes into contact with fi re, a poisonous gas may occur. Be aware that refrigerants
may not contain an odour.
●
After completion of installation work, check to make sure that there is no refrigeration
gas leakage. If the refrigerant gas leaks into the room, coming into contact with fi re
in the fan-driven heater, space heater, etc., a poisonous gas may occur.
●
Unauthorized modifi cations to the air conditioner may be dangerous. If a breakdown
occurs please call a qualifi ed air conditioner technician or electrician. Improper repairs
may result in water leakage, electric shock and fi re, etc.
