NOTE
NOTE: FOR PRODUCT INSTALLATION
: Prior to installation
If there is no fixed refrigerant piping:
While choosing a location, be aware that you should leave ample room for a wall hole (see
Drill wall hole for connective piping step) for the signal cable and refrigerant piping that
connect the indoor and outdoor units. The default position for all piping is the right side of
the indoor unit (while facing the unit). However, the unit can accommodate piping to both
the left and right.
Distance from ceiling is determinded
by the installation method.
If no need the back holder to prop up the unit:
Finishing the pipe and cable connections before mount the
indoor unit on the wall. If the instllation height is limited, 5cm
from the ceiling is allowable, but this can lower product
performance. To ensure enough space to install and remove
the top air filter, keep at least 10cm or more from the ceiling.
Need the back holder to prop up the unit:
If connecting pipe and cable with front panel open, the
minimum distance from ceiling is 22cm or more, if
connecting pipe and cable without front panel(remove it) ,
the minimum distance from ceiling is 11cm or more.

Determine wall hole location
Correct orientation of Mounting Plate
Remove the screw that attaches the
mounting plate to the back of the
indoor unit.
Secure the mounting plate to the wall
with the screws provided. Make sure
that mounting plate is flat against
the wall.

Determine the location of the wall hole based
on the position of the mounting plate. The
dotted rectangular box on the right figure
shows the size of your product.
The size of the wall hole is determined by the connective pipes. When the size of the gas side
connective pipe is 16mm(5/8") or more, the wall hole should be 90mm(3-9/16"). For the size of
connective pipe is less than 16mm(5/8"), the wall hole should be 65mm(2-1/2").

Drill wall hole
Using a 65mm (2.5") or 90mm(3.54")
core drill(depending on models ), 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 5mm to
7mm (3/16-5/16"). This will ensure
proper water drainage.
Place the protective wall cu in the hole.
This protects the edges of the hole and
will help seal it when you finish the
installation process.

Note on Pipe Length
Connection Instructions – Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
Measure the distance between the indoor
and outdoor units.
Using a pipe cutter, cut the pipe a little
longer than the measured distance.
Make sure that the pipe is cut at a perfect
90° angle.
Oblique Rough Warped
90°
Maximum Length and Drop Height of Refrigerant Piping per Unit Model
DO NOT DEFORM PIPE WHILE CUTTING
WARNING
The length of refrigerant piping will aect the performance and energy eciency of the unit. Nominal
eciency is tested on units with a pipe length of 5 meters (16.5ft). ( In North America, the standard pipe
length is 7.5m (25’) For the R290 refrigerant models, no refrigerant can be added and the maximum .
length of refrigerant pipe should not exceed 5 meters(16.5ft).A minimum pipe run of 3 metres is
required to minimise vibration & excessive noise. Connection Instructions – Refrigerant Piping.
Be extra careful not to damage, dent, or deform the pipe while cutting. This will drastically reduce
the heating eciency of the unit.
