Unit Installation
Mounting of the Unit
If the unit is to be installed on a roof surface or on a concrete base, observe the following guidelines:
1. The provided base pan rises the heating pump 2” above the installation base.
2. If the unit is to be raised over the roof surface, use 4” x 4” boards (or equivalent) placed in a
manner that may allow weight to be evenly distributed and to prevent the transmission of noise
and vibrations. See Figure 3.
Note: Avoid the blockage of drain openings as shown in Figure 3.
3. If the unit is to be raised to avoid seasonal snow/ice buildup, make sure the elevation support
is sturdy enough to avoid unit’s falling or tilting.
Note: See Figure 4 for proper unit setting guidelines.

Factory Recommendation for Mounting the Unit
1. Before installation, clean the mounting surface. Important = The cement base must comply
with local codes and be thick enough to sustain the installation of fasteners.
2. Center and level the unit over the base or mounting surface.
3. Using the provided L-shaped bracket, mark the boring holes over the concrete and bore holes
of at least 1/4” additional depth as compared to the bracket to be used. Important = Drill
screws should not exceed 3/8” in length to avoid harming the coil.
4. Tighten brackets and drill screws following conventional practices for the installation of these
supports. See Figure 4.
Note: Use one bracket at each side. For further stability, use 2 brackets at each side.
Note: Do not over-tighten brackets in order to avoid weakening the concrete material.
