●Select the location where a space is more
than 100 cm. as shown in fig.3 also ensure
that the position does not interfere with
light fitting, sprinkle head, etc.
●Determine the ceiling hole by using the
paper pattern.
●Determine the mounting position on ceiling
by using position in
the paper pattern.

●Hang the four mounting rods to the positions
marked as picture shown (using twelve nuts and
eight washers to support the suspension
brackets). Suspend the unit to the mounting rods.
Lock the nuts, ensure for good drainsage, and
check whether the unit is on horizontal level by
using leveling guage.

●Install the leveling metal plate to adjust the gap
between the unit and a ceiling, fixing the screws
following No. in paper pattern.
●Remove four screws (M8). Fix the front panel
with the units by tighten up four screws (M8).

■WHERE TO INSTALL OUTDOOR UNIT :
●The location is sufficiently isolated so that the running
noise and the hot exhaust air do not disturb the
users or their neighbors.
●Easy access to check and to maintain.
●Ensure the spaces indicated by arrows from the wall,
ceiling, fence, or other obstacles.
●The foundation must be solid enough to bear the
weight and vibration of the unit.
●The space around the unit is adequate for ventilation.
●The location is not close to any flamable gases.
CAUTION
Installation in the following places may cause problems.
If it is unavoidable to use such places, consult with your distributor or dealer.
●A place with machine oil.
●A saline place such as a place very close to a seashore.
●A place with sulphur gas.
●A place where high-frequency waves are generated by radio equipment, welder and medical equipment.

■PIPE & ELECTRICAL WIRE CUTTING
●Use cutting tools easily found in the market.
●Measure precisely both outer & inner pipe.
●Provide a little bit longer pipe than the measurement.
●Wire must be 1.5 m. longer than the refrigerant tube.
■FLARING THE PIPE END
■REAMING
●Clean inside of the inner refrigerant tube.
●While reaming, the tube end must be on the top of the
reamer to prevent any dust going back into the tube.
●Flare both ends of the pipe with flaring kit by fitting the
flare nut on the pipe before flaring. Set the die on the
pipe so that pipe end is 0.5 mm. above top of the die.
Check if the pipe end is even and perfectly round.

4.1Select copper pipes for gas and liquid as informed in specific table (see the pipe table below)
4.2 For dust and moisture protection, before assembly of the pipe and its insulation, both ends of the
pipe must be covered.
4.3 Avoid pipe bending as much as possible. If it is necessary, the bending radius must be more than
3 cm. or 4 cm.
4.4 The connection between an indoor unit and an outdoor unit.
●Unscrew the flare nut for releasing pressure gas in the indoor unit. If there is no high pressure gas
blowing out, it is the signal of a leaking indoor unit.
●Fit the flare nut to the liquid pipe. Flare the pipe's end with flare tool.
●Tighten both flare nuts into gas pipe and liquid pipe at the indoor unit with two holding spanners.

■DRAIN PIPE OUTLET
●A drain pipe and refrigerant pipes must be covered by insulation to prevent condensation.
Caution on drain collecting piping.
Use a larger diameter pipe as it comes near the end.
The size of
pipes marked
with *must be at
least 40 mm (1-5/8),
depending on the number
of indoor units installed.
Install the drain pipe at a lower level immediately
after the unit.
