Installation

General

1 PRE-INSTALLATION CHECK-POINTS

Before attempting any installation, the following points
should be carefully considered:
a Structural strength of supporting members.
(rooftop installation)
b Clearances and provision for servicing.
c Power supply and wiring.
d Air duct connections.
e Drain facilities and connections.
f Location for minimum noise.

2 LOCATION

These units are designed for outdoor installations. They
can be mounted on a slab or rooftop. They are not to be
installed within any part of a structure such as an attic,
crawl space, closet, or any other place where condenser
air flow is restricted or other than outdoor ambient condi-
tions prevail. Since the application of the units is of the
outdoor type, it is important to consult your local code
authorities at the time the first installation is made.

Outside Slab Installation

(Typical outdoor slab installations are shown in Figures 5 and 6.)
1 Select a location where external water drainage cannot
collect around the unit.
2 Provide a level concrete slab extending 3" beyond all four
sides of the unit. The slab should be sufficient above
grade to prevent ground water from entering the unit.
IMPORTANT: To prevent transmission of noise or vibration,
slab should not be connected to building structure.
3 The location of the unit should be such as to provide
proper access for inspection and servicing.
4 Locate unit where operating sounds will not disturb owner
or neighbors.
5 Locate unit so roof runoff water does not pour directly on
the unit. Provide gutter or other shielding at roof level. Do
not locate unit in an area where excessive snow drifting
may occur or accumulate.

Clearances

The following minimum clearances must be observed for
proper unit performance and serviceability.
1 Provide 12" minimum clearance at the front of the unit.
Provide 36" minimum clearance at the left and 18" on the
right side of the unit for service access.
2 Provide 60" minimum clearance between top of unit and
maximum 3 foot overhang.
3 Unit is design certified for application on combustible
flooring with 0" minimum clearance.
4 See Figure 5 for illustration of minimum installation-ser-
vice clearances.
*5 When used with economizer, 12" minimum dimension at
unit front becomes 57".
