Fix Unit to the wall
¡
1. Fix the Unit onto the wall as the figure
indicates. (field supplied stay)
2. Ensure the foundation so that avoid the
deforming and noise.
3. In case of prevention from vibration
transfer to the building, use rubber Mat.
Suspended unit
¡
1. Suspend the unit as the drawing
indicates.
2. Ensure that wall can resist the Outdoor
unit weight indicated in specification
label plate.
3. It is recommended to select each foot
support to bear the full weight of the
unit (in order to consider stress fatigue
applied when unit is working too).
Installing location where the unit will be exposed to strong wind.
¡
Follow the instructions below to install
on the rooftop or a location without
surrounding buildings, where strong
wind is expected against the product.
1. Choose a location where the outlet
or inlet side of the product will not be
exposed to strong wind.
2. When the outlet is exposed to strong
wind:
Direct strong wind may cause lack
of air flow and adversely affect to the
operation.
11 REFRIGERANT PIPING & REFRIGERANT CHARGE
11.1. PIPING MATERIALS
1. Prepare locally-supplied copper pipes.
2. Select the piping size with the correct thickness and correct
material which can have sufficient pressure strength.
3. Select clean copper pipes. Make sure there is no dust and
moisture inside. Blow the inside of the pipes with oxygen free
nitrogen to remove any dust and foreign materials before
connecting pipes.
NOTE:
A system with no moisture or oil contamination will give maximum
performance and lifecycle compared to that of a poorly prepared
system. Take particular care to ensure all copper piping is clean
and dry internally.
There is no refrigerant in the cycle of the indoor unit.
CAUTION:
Cap the end of the pipe when pipe is to be inserted through a
hole

CAUTION:
Pay attention to the following for
installation:
1. Installation shall ensure that outdoor
unit will not incline, vibrate, make
noise or fall down by a blast of
wind or in an earthquake. Calculate
quake-resistance strength to
ensure that installation is strong
enough against falling. Fix the unit
with wires (field supplied) when
installing in a location without walls
or windbreak and likely exposed to
a blast of wind.
2. To use a vibration-proof mat, fix four
places to the front and back.
CAUTION:
Excessive strong wind against the outdoor
unit outlet may cause inverse rotation and
damage the fan and motor.
Do not put pipes on the ground directly without a cap or vinyl tape
at the end of the pipe
If piping installation is not completed until next day or over a
longer period of time, braze off the ends of the piping and charge
with oxygen free nitrogen through a Schrader valve type access
fitting to prevent moisture and particle contamination.
Do not use insulation material that contains NH3 because it can
damage cooper pipe material and can be a source of future
leakage.
Completely insulate both refrigerant gas piping and liquid piping
between the indoor unit(s) and the outdoor unit.
If not insulated, dew will ocur on the piping surface
