Step 2: Unfastening the operation panel and
detaching the filter
1.
Open the packaging and take out the indoor
unit. Remove the protective tape and any
components.
2.
Please take off the lower front panel before
connecting the pipes/wires.
Pull down the two knobs on the grille, take
off the two screws, then the air-inlet grille
goes free.
3.
Remove all of the accessories placed inside
the bottom cavity of the indoor unit.
Step 3. Remove the fasteners from the roller
(only found on selected models)
1.
Check to see whether the roller on the indoor
unit has any fasteners holding it in place and
tear off the notice sticker.
2.
Remove the fasteners from the roller
according to the directions on the sticker.
1.
Measure the position of the holes for
installation.
2.
Insert the M8 bolts into the unit while it is on
the floor (the amount of bolts used depends
on the number of holes on the unit's chassis).
3.
Lift up the indoor unit so that the installation
holes cover the bolts, then fasten the nuts
onto the bolts and tighten them.
4.
Check that all of the accessories match those
found on the “Installation Diagrams and
Accessories” as shown on the previous page.
Step 4. Fastening the indoor unit (to prevent
it from falling down)
•
Take out the protective wedge and
measure the correct size.
•
Use the self-tapping screws to fasten the
protective wedge to the top cover of the
indoor unit.
•
Fasten the other end of the wedge tightly
to the wall using the self-tapping screws.
If further support is needed to prevent the
unit from falling down, a protective wedge
can be installed. The installation procedure
for this wedge is as follows:
Lower front
panel
1.
Lay the connecting piping flat on the ground.
Place the drainage hose, refrigerant pipe, and
all electrical wiring (making sure that both
ends are arranged correctly) next to the piping.
2.
Using the drainage hose as a guide, measure
and adjust the length of the low voltage
wiring, high voltage wiring, any other
electrical wiring, and refrigerant pipe. Use
cable ties to initially fasten them in place.
Step 6. Piping and binding
1.
Remove the metal rodent-proof mesh from
the piping found on the unit by gently
tapping on it.
Step 5. Installing the rodent-proof mesh
2.
Insert the ratproof board into the unit and
hold it in place tightly.
3.
Use a knife to cut a small hole by following the
markings on the ratproof board.
First remove the metal
Then attach the ratproof
board into the hole

Step 8: Drill wall hole for connective piping
1.
Determine the location of the wall hole
based on the location of the outdoor unit.
2.
Step 7: Applying the sealant putty and
installing the wall hole cover
1. Tidy up the already bound piping.
2. Evenly apply the sealant putty to the gaps
between the piping and the wall, then press
on the putty firmly.
3. Pull the wall hole cover apart to open it.
After fastening tightly to the piping, push it
into the hole in the wall to securely fasten it
to the wall and complete the installation.
•
Only models with a ventilation function
contain ventilation ducting.
•
The amount and type of electrical wiring
used may vary according to the specific
model.
•
The ends of the ventilation ducting and
electrical wiring are different, please check
carefully before starting to bind.
Using a 65-mm (2.5”) core drill, drill a hole in
the wall. Make sure that the hole is drilled at a
slight downward angle, so that the outdoor
end of the hole is lower than the indoor end
by about 1cm (0.4”). This will ensure proper
water drainage . Place the protective wall cuff
in the hole. This protects the edges of the hole
and will help seal it when you finish the
installation process.
4.
Use adhesive vinyl tape to begin binding the
piping together. Start binding the tape at the
bottom end of the drainage hose, and make
sure that the connectors are secured tightly.
3.
Arrange the piping so that the drainage hose
is on the bottom, the connecting piping is in
the middle, and the electrical wiring is at the
top.

The electrical wiring, drainage hose, and
refrigerant pipe must exit the binding in a
suitable place. All binding must be mutually
connected, evenly applied, and aesthetically
pleasing.
