CAUTION
The unit body must be completely aligned with
the hole. Ensure that the unit and the hole are
the same size before moving on.
2. Install and fit pipes and wires after you have
finished installing the main body.When
choosing where to start, determine the
direction of the pipes to be drawn out.
Especially in cases where there is a ceiling
involved, align the refrigerant pipes, drain
pipes, and indoor and outdoor lines with their
connection points before mounting the unit.
3.
Install hanging screw bolts.
4. After you select an installation location,align
the refrigerant pipes, drain pipes, as well as
indoor and outdoor wires with their
connection points before mounting the unit.
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 washers and nuts
provided.
7. Install the four suspension bolts.
8. Mount the indoor unit with at least two
people to lift and secure it. Insert suspension
bolts into the unit’s hanging holes. Fasten
them using the washers and nuts provided.
(See Fig. 4.11).
9. Mount the indoor unit onto the hanging
screw bolts with a block. Position the

Step 4: Duct and accessories installation
NOTE: 1. Do not put the connecting duct
weight on the indoor unit.
2. When connecting the duct, use an
nonflammable canvas tie-in to prevent
vibrating.
3. When connecting duct, install in place prone
to takedown for maintenance.
4. Change the fan motor static pressure
corresponding to external duct static pressure.
5. If installed in place like meeting room where
noise is easy to be perceived, design isolation
booth and internal duct underlayer to muffle
the duct system and weaken the air
encounter noise in the duct.
1. The air inlet and air outlet duct should be far
enough apart enough to prevent air outlet
entering Air Inlet.
Step 3: Diagrammatic sketch for installing
the main body
Installing the dust proof net and canvas air
passage
2. There is dust filter on the indoor unit.
3. Please attach the outside air duct to the indoor
air outlet/inlet flange by using the type
ST3.9 x 10 screw.
