CAUTION & SUGGESTIONS TO FOLLOW PRIOR TO INSTALLATION
* Either the indoor unit or the outdoor unit can be
higher, but the height difference must comply the

* 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.
* Make P-trap if elevation drop difference is more
than 25", as illustrated below.

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 unit to make sure the installation location is firm enough to hold the weight of the whole unit and is
convenient to install, maintain, and service.
* 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 drill 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.
