Safety Cautions
Please carefully read this "Safety Cautions" before
installing air conditioner so as to ensure correct
installation.
The following cautions are divided into two categories,
related to safety and of great importance, please
carefully read.
Warning
…Inattention will lead to death or
serious injury.
Caution
…Inattention will lead to injury or
machine damage, and may also cause serious injury
according to different conditions.
Installation operation must be conducted by
professional personnel. Do not conduct without
approval.
Please install the air conditioner in a solid place
sufficient to bear the weight.
Instable base may lead to air conditioner falling
and cause damage.
Please use separate circuit for power supply. The
operation of all the electric parts must be in
accordance with the local laws and specifications
as well as this instruction.
The operation shall be conducted by the
electrician with professional qualification.
Insufficient
capacity
or
improper
electric
operation may cause electric shock or fire hazard.
Use the specification designated wires; all the
wires shall be connected well to make connecting
terminal and wire free from external force
drawing.
Poor connection and improper installation may
cause fire hazard.
Straighten out and lay flat when connecting power
line, remote controller and wire controller line so
as to make electric parts and wire slot box cover
fastened down.
If any refrigerant gas leakage in installation,
immediately open
door and window for
ventilation.
The refrigerant gas will generate toxic gas when
meeting combustion sources such as air heater,
furnace and stove.
Please power off first before touching electronic
parts.
Do not touch the switch with wet hand.
Touching switch with wet hand may cause electric
shock.
Air conditioner must be earthed.
Earthing wire shall not be connected to gas pipe,
tap water pipe, lightening rod and telephone line.
Poor earthing may lead to electric shock accident.
Leakage earthing leakage breaker must be
installed.
If leakage earthing breaker is not installed, there
will be electric shock hazard or fire hazard.
Please arrange drainage piping according to this
instruction to guarantee smooth drainage, and
insulate the piping in case of condensed water
accumulation.
Improper piping may lead to water leakage and
soak household items.
Air conditioner, power line and connecting line
shall be far away from more than 1m at least from
such electrical equipment as television set and
radio
to
prevent
from
interference
of
electromagnetic wave and noise.
In the room equipped with fluorescent lamp
(inverter or quick start type), the signal
transmission distance of the remote controller may
not reach the preset value.
The indoor machine shall be away from
fluorescent lamp as far as possible.
Installation should not be conducted in the
following places:
(a)
Place where mineral oil smoke or mist or steam
is diffused, for example, kitchen.
Plastic parts may be deteriorated and damaged.
(b)
Place where there is corrosive gas such as sulfur
dioxide.
Copper pipe or welding part may be corroded to
cause refrigerant leakage.
(c)
Place which is close to the machine generating
electromagnetic wave.
Electromagnetic wave may influence the control
system to make the air conditioner incapable of
normally operating.
(d)
Place where there is combustible gas leakage,
carbon fiber or combustible dust floating, or
volatile combustible placing such as gasoline or
diluent.
The use of air conditioner in such places may
cause fire hazard.
Please do not touch the fin of the heat exchanger.
Improper touch may cause machine damage and
personal injury.
Please pay special attention to product handling.
Do not handle by lifting PP strap in case of PP
strap rupture to damage unit and harm person.
2.
Before Installation
Air conditioner shall not be unsealed before
moved to the installation site. If it is necessary to
unseal, measures shall be taken after unsealing to
avoid damaging or scratching air conditioner.
When moving the air conditioner during or after
unsealing, do not apply force to refrigerant piping,
drainage pipe or other plastic parts in order to
avoid damaging air conditioner.
Before air conditioner installation, please confirm
whether the refrigerant used for the unit is R22 or
