RECOMMENDED ELEVATED INSTALLATION

3.6 UNIT MOUNTING

If elevating the heat pump, either on a flat roof or on a slab, observe the
following guidelines.
• The base pan provided elevates the heat pump 2" above the base pad.
• If elevating a unit on a flat roof, use 4" x 4" (or equivalent) stringers positioned
to distribute unit weight evenly and prevent noise and vibration (see Figure 2).
NOTE: Do not block drain openings shown in Figure 1.
• If unit must be elevated because of anticipated snow fall, secure unit and ele-
vating stand such that unit and/or stand will not tip over or fall off. Keep in mind
that someone may try to climb on unit.
3.7 FACTORY-PREFERRED TIE-DOWN METHOD
INSTRUCTIONS:
IMPORTANT: These instructions are intended as a guide to securing equipment for wind-
load ratings of "120 MPH sustained wind load" and "3-second, 150 MPH gust." While this
procedure is not mandatory, the Manufacturer does recommend that equipment be prop-
erly secured in areas where high wind damage may occur.
STEP 1: Before installing, clear pad of any dirt or debris.
IMPORTANT: The pad must be constructed of industry-approved materials, and
must be thick enough to accommodate the concrete fastener.
STEP 2: Center basepan on pad, ensuring it is level.
STEP 3: Using metal straps as guides, mark spots on concrete where 4 holes will be
drilled (see Figure 1).
