Important Points of Safety

!
Attention
l Ensure ventilation of the room
if the machine is used with
burning facilities. Deficient
ventilation can cause oxygen
shortage.
l Check whether installation
bench of the machine is
damaged after a long period
of use. Machine on damaged
bench may fall down and cause
human injury or other damage.
l In place where winds produced
by the machine can reach, donít
lay any animals or plants which
may be hurt otherwise.
l Donít put vases containing water
or other else on the unit assembly.
Otherwise, the machine may be
immersed internally and result in
bad electric insulation causing
electric shock.
The is machine CANNOT be
l
used for the purpose of prese-
rving food, animals, plants,
precision instruments and
artwork etc., which may be
destroyed otherwise.
l DONíT replace fuse with ma-
terial other than fuse of proper
capacity. Replacing fuse with
metal wire or copper etc. can
cause fire hazard or other faults.

l DONíT lay any burning facilities
in place where winds produced by
the machine can reach. Incomplete
combustion of burning facility may
be caused otherwise.
DONíT clean the machine with
l
water. Electric shock may occur
otherwise.
l DONíT put flammable spray
articles nearby or spray them to
the machine. Fire hazard may
occur otherwise.
DONíT operate switch with wet
l
hand. Electric shock may occur
otherwise.
l Stop operation and shut down
manual power switch before
cleaning and maintenance.
l The power supply MUST be of
rated voltage and connected with
special electrical supply circuit.

3. Air duct insulation
Insulation layer is needed for air supply and return duct. First, paste a glue nail to the
air duct, and then attach the insulation cotton that has a tinfoil layer and use the glue
nail cover to fix. Finally, seal the air duct interface with tinfoil adhesive tape closely.

Installing the suspension screw:
Use M8 or M10 suspension screws (4, prepared in the field) (when the suspension screw
height exceeds 0.9 m, M10 size is the only choice). These screws shall be installed as
follows with space adapting to air conditioner overall dimensions according to the original
building structures.
Wooden structure
A square wood shall be supported by the
beams and then set the suspension screws.
