GENERAL INSTALLATION GUIDELINES
Mounting of Indoor Unit
Detaching Front Panel from Indoor Unit
Before you can mount the indoor unit to the wall, you must remove
the front cover. Removal will allow you to knock out any side holes
for the drain hose, as well as allow you to mount the unit without
damaging the front cover.
It is recommended that the front panel not be re-attached to the indoor
unit until the final test has been run which will ensure that all electrical and
piping connections are working properly.
Procedure
1. Lay the indoor unit on a flat surface, and then pull the upper part
of the front panel away from the body.
2. Lift up the front panel so that the bottom part of the unit is visible.

3. Detach the front cover, by removing the two screws.
4. Remove the front cover away from the body, and be sure to
disconnect the front panel connector as shown below.
Removing Side Bottom Covers and Piping Hole Knockout
Before mounting the indoor unit, you may need to remove either the
right or left bottom side covers and the piping hole knockout, in order
to pass the drain hose and piping through. This procedure should be
done after removal of the front panel of the indoor unit.
Procedure
1. Using a phillips head screwdriver, remove the center bottom
screw from the L-bracket tube holder (Figure 8).
2. Detach one of the side covers (either right or left depending on
how you want to place the piping and drain hose).
3. Knockout the piping hole from the detached side cover.
After knocking out the piping hole from the side cover, be sure to smooth
or cut any burrs around the hole. Burrs left on can lead to physical cuts
and scrapes.
If you are planning to create a piping hole directly through the rear wall
you might not need to knockout the piping hole from the side cover.
