WARNING
• Securely install the indoor unit on a structure
that can sustain its weight. If the structure is
too weak the unit may fall causing personal
injury, unit and property damage or death.
• DO NOT install the indoor unit in the
bathroom or laundry room as excessive
moisture can short the unit and corrode the
wiring.
CAUTION
• Install the indoor and outdoor units, cables
and wires at least 1m (3.2’) from televisions
or radios to prevent static or image
distortion. Depending on the appliances, a
1m (3.2’) distance may not be sufficient.
• If the indoor unit is installed on a metal
part of the building, it must be electrically
grounded.
Indoor Unit Installation Instructions

CAUTION
The unit body should align perfectly with the
hole. Ensure that the unit and the hole are the
same size before moving on.
2. Carry out the pipe and line operation in the
ceiling after finishing the installation of the
main body. While choosing where to start the
operation, determine the direction of the pipes
to be drawn out. Especially in case there is a
ceiling, position the refrigerant pipes, drain
pipes,indoor & outdoor lines to the connection
places before hanging up the machine.
3. The installation of hanging screw bolts.
4. After the selection of installation location,
position the refrigerant pipes, drain pipes,
indoor & outdoor wires to the connection
places before hanging up the machine.
5. Drill 4 holes 10cm (4”) deep at the ceiling
hook positions in the internal ceiling. Be sure
to hold the drill at a 90° angle to the ceiling.
6. Secure the bolt using the included washers
and nuts.
7. Install the four suspension bolts.
8. Mount the indoor unit. You will need two
people to lift and secure it. Insert suspension
bolts into the unit’s hanging holes. Fasten
them using the included washers and nuts
(See Fig. 4.8).
9. Overhang the indoor unit onto the hanging
screw bolts with block. Position the indoor
unit in a flat level by using the level indicator,
unless it may cause leakage. (See Fig. 4.9).

Step 3: Duct and accessories installation
NOTE: 1.Do not put the connecting duct weight
on the indoor unit.
2.When connecting duct, use inflammable
canvas tie-in to prevent vibrating.
3.Insulation foam should be wrapped outside the
duct to avoid condensate and internal duct
underlayer shall be added to reduce the noise
for special requirement.
1. Install the filter(optional) according to air inlet
size.
5. Please refer to the following static pressure to
install.
Change the fan motor static pressure
corresponding to external duct static pressure.
2. Install the canvas tie-in between the body and
duct.
3. Air inlet and air outlet duct should be apart far
enough to avoid air passage short-circuit.
