* Either the indoor unit or the outdoor unit can be higher, but the height difference must follow with the stated
requirements.
* Try to reduce the bending of the piping line as much as possible so as to avoid possible negative impacts upon
the performances of the units.

Install Mounting Plate and Drill Hole for Combination of Copper Line/Wire Cable/Drain Hose
NOTES:
Anchors must be put into the holes, where the solid
arrows are pointing, as shown above, to secure the
mounting plate firmly and to hold the weight of indoor
unit. If more screws/anchors are to be used, make
sure to keep the two holes close to each other, at
least 2 inches apart.
Mounting plate should be attached to the structural
part of the wall. Minimum clearance, as shown below,
is required in order to ensure proper airflow and
enough service room.
INSTALL WALL MOUNT PLATE
* Check unit to make sure the unit is in good shape and ready to install.
* Check to make sure the installation location is firm enough to hold the weight of the whole unit and is
convenient to install, maintain, service and close to the indoor unit but not causing noise or airflow issues to
neighbors.
* Install Indoor unit. Enough anchor bolts/nuts shall be used to secure mounting plates for indoor units.
Brackets should be at level position.
*
Mark drill positions. At least 4 anchor holes, one at each perimeter corner of the plate are needed to secure the
plate, where the bold arrows are pointing, as shown in the picture above. Refer to the specification sheet for
unit weight so that enough anchors are installed at proper positions.
* Pre-drill guiding holes where are marked for anchors or screws on the wall
* Confirm the position of the holes and finish drilling to the depth needed for anchors (NOT for screws)
* Align mounting plate holes with those holes drilled on the wall and put anchors or screws into the holes to
secure mounting plate.

Locate the center where the hole will need to be
drilled.
Drill the holes of 2.5-3Inch diameter. A down pitch
about 1/4" per foot, as illustrated below, is needed
for the hole, in order to drain the condensate
properly.

INSTALL DRAIN PIPE AT INDOOR
The drain hose must be placed beneath the copper
pipes and MUST NOT be hunched or bended
sharply.
Do not pull the drain hose too hard, otherwise it
may break.
Before passing drain hose through the hold, wrap
with insulation to keep from possible damage.
The copper pipe and the drain hose must be
wrapped by piping wrap.
Insulation pad (underlay) should be used where
the pipe contacts the wall.
Slice the
insulation
before
bending.
Hold the 90
degree bend
root, bend one
tube one time,
slowly, no
quicker than
10 seconds/
90 degree
bend.
* If pipes need to come out of the rear side (facing
the front of indoor unit) of the indoor unit, no need
to snap off anything.
* If pipes need to be rerouted to a different direction
from the one preset at factory (towards left side, if
facing the front cover of indoor unit), lay down the
indoor unit on soft cushion or foam. Don't rub the
plastic casing.
* In order to keep from damaging the pipes, need to
bend the copper tubing set gently and slowly (finish
bending no less than 10 seconds/90 degree), by
holding at the root of the original 90 degree bend
nicely and firmly. Don't rub two copper lines during
bending. Better to cut off the insulation and bend
the two pipes one by one, not two together.
