RECOMMENDED ELEVATED INSTALLATION
• Do not obstruct the bottom drain opening in the heat pump base pan. It is
essential to provide defrost condensate drainage to prevent possible refreezing
of the condensation. Provide a base pad for mounting the unit, which is slightly
pitched away from the structure. Route condensate off the base pad to an area
which will not become slippery and result in personal injury.
• Where snowfall is anticipated, the heat pump must be elevated above the base
pad to prevent ice buildup that may crush the tubing of the heat pump coil or
cause fin damage. Heat pump units should be mounted above the average
expected accumulated snowfall for the area.

3.5 CUSTOMER SATISFACTION ISSUES

• The heat pump should be located away from the living, sleeping and recre-
ational spaces of the owner and those spaces on adjoining property.
• To prevent noise transmission, the mounting pad for the outdoor unit should
not be connected to the structure, and should be located sufficient distance
above grade to prevent ground water from entering the unit.

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" [50.8 mm] above the base
pad.
• If elevating a unit on a flat roof, use 4" x 4" [101.6 mm x 101.6 mm] (or equiva-
lent) 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.
