VI. INSTALLATION
A. GENERAL
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points should be carefully consid-
ered:
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 conditions prevail. Since the application
of the units is of the outdoor type, it is important to consult your local code authori-
ties at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figure 2.)
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.
C. CLEARANCES
The following minimum clearances must be observed for proper unit performance
and serviceability.
1. Provide 30" minimum clearance at the front and 18" on the right side of the unit
for service access. Provide 12" minimum clearance on the left side of the unit for
air inlet.
2. Provide 60" minimum clearance from top of unit.
3. Unit is design certified for application on combustible flooring with 0" minimum
clearance.
4. See Figure 2 for illustration of minimum installation-service clearances.
D. ROOFTOP INSTALLATION
1. Before locating the unit on the roof, make sure that the strength of the roof and
beams is adequate at that point to support the weight involved. (See specification
sheet for weight of unit.) This is very important and user’s responsibility.
2. The unit should be placed on a solid and level platform of adequate strength.

CAUTION
R-410A systems operate at higher pressures than R-22 systems. Do not use
R-22 service equipment or components on R-410A equipment.
