STEP 4: REMOVE FRONT PANEL AND FACE PLATE

To facilitate pipe and cable installation remove the front panel and face plate on the unit.

1. Slide the two tabs at the top of the front panel inward until they click.

2. Remove the four screws holding the face plate in place. Open at the bottom 30 and lift off the

face plate.

STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPING

1. Determine the location of the wall hole based on the location of the outdoor unit.

2. Using a 2 1/2" (65mm) core drill for units with a gas side connective pipe less than 5/8" (16mm),

or 3 1/2" (90mm) for units with a gas side pipe greater than or equal to 5/8" (16mm), 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 3/16 - 1/4" (5mm to 7mm). This will ensure

proper water drainage.

3. Place the protective wall hole sleeve (ﬁeld supplied) into the hole. This protects pipes and

cables from sharp edges and will help seal the opening when you ﬁnish the installation process.

After the sleeve is inserted through the wall, connect the wall hole sleeve cover to the wall

sleeve on the outside end. Make sure the cover is ﬂush with the outside wall.

3. Using a screwdriver, remove the string attached to the front panel. Gently let the front panel

fall forward and remove it.
