Ceiling Mounting the Convertible Unit

Firmly tighten the nuts and bolts to prevent the unit from
falling.
Note:
Use caution when selecting the mounting location. Determine where
existing wiring and/or piping are routed through the ceiling and avoid
these areas when mounting the unit and drilling access holes.
1. Be sure the mounting location is strong enough to prevent
vibration.
2. Refer to Figure 6. Measure and mark the positions of the hang-
ing bolts and the piping hole.
3. Drill holes in the ceiling for the four ceiling anchor bolts.
4. Insert the nuts and washer onto the hanging bolts to lock the
bolts on the ceiling.
5. Firmly mount the hanging bolts to the anchor nuts.
6. Refer to Figure 7. Secure the unit hangers on the hanging bolts
with nuts, washers and lock washers.
7. Before final tightening of the nuts, determine at what angle the
unit will be positioned. Refer to Figure 8 for examples of correct
and incorrect positioning. The unit must be positioned so that
condensation will flow from the unit through the drain pipe.
8. Adjust the nuts to position the unit as desired. Tighten the nuts to
prevent the unit shifting position.
Prepare Refrigerant Pipes for
Installation
1. Press on the upper side of the pipe clamp.
2. Slowly unfold the pipes downward as shown in Figure 9. Do not
move the pipes outward as shown in Figure 10.
3. Carefully bend the pipes to the left side of the chassis. Refriger-
ant pipes will be connected in a later step.
