Hanging the Indoor Unit Frame
1. Remove the installation guide and hang the indoor unit on the top two (2) screws. Verify
the indoor unit is hanging securely on the screws.
2. Align the holes at the bottom of the indoor unit to the mounting holes. Tighten first the top
screws, then tighten the bottom screws.
3. Verify that the indoor unit is completely secured to the wall by gently shaking it up and
down.

Preparing the Refrigerant and Drain Piping Connections
1. Depending on the installation requirements, route the indoor unit refrigerant piping and the
drain hose to the left, right (see guidelines below), or rear of the frame.
2. Bundle the piping and drain hose with tape where they meet near the indoor unit frame. Po-
sition the drain hose at the bottom of the bundle (positioning the drain hose at the top of the
bundle may cause the drain pan to overflow inside the indoor unit).

Figure 53:Preparing the Refrigerant /
Drain Connections.
1. Press on the top of the clamp, and then
slowly guide the piping downward.
2. Bend the piping to the right side of the
indoor unit frame.
Do not bend the piping / drain hose from side to side, it may damage the components.
