WARNING
These instructions are intended as a general guide and do
not supersede national or local codes in any way.
Authorities having jurisdiction should be consulted before
installation+
When servicing or repairing HVAC components, ensure
the fasteners are appropriately tightened. Table 1 shows
torque values for fasteners+
Table 1. Torque Requirements
Parts Recommended Torque
Service valve cap 8 ft.- lb. 11 NM
Sheet metal screws 16 in.- lb. 2 NM

CAUTION
position that will transmit sound or vibration to the
living area or adjacent buildings.
2+ Install the unit high enough above ground or roof to
allow adequate drainage of defrost water and prevent
ice build-up.
3+ In heavy snow areas, do not locate unit the where
snowdrifts will likely build. The unit base should be
elevated above the depth of average snows.
NOTE - Elevation of the unit may be accomplished by
constructing a frame using suitable materials. If a
support frame is constructed, it must not block drain
holes in unit base.
4+ Locate the unit so prevailing winter winds will not blow
into the coil.
5. Locate unit away from overhanging roof lines which
would allow water or ice to drop on, or in front of, coil
or into unit.
NOTES:

Outdoor units operate under a wide range of weather
conditions; therefore, several factors must be considered
when positioning the outdoor unit+
Position the unit to allow adequate airflow and servicing
clearance. Maintain a minimum clearance of 24 inches
(610 mm) between multiple units as illustrated in figure 1+
1+ Place a sound-absorbing material, such as Isomode,
under the unit if it will be installed in a location or
Figure 1. Installation Clearances
SLAB MOUNTING
When installing unit at grade level, the top of the slab
should be high enough above grade so that water from
higher ground will not collect around the unit. The slab
should have a slope tolerance away from the building of 2
degrees or 2 inches per 5 feet (50 mm per 1500 mm) to
prevent ice build-up under the unit during a defrost cycle+
NOTE - If necessary for stability, anchor unit to slab as
described in "Stabilizing unit on uneven surfaces".

ELEVATING THE UNIT (SMALL-BASE UNITS)
If additional elevation is necessary, raise the unit by
extending the length of the unit support feet. This may be
done by cutting four equal true-cut lengths of Schedule
(SCH) 40, 4" (101.6mm) piping to the height required as
illustrated in figure 3.
NOTE - Keep the height of extenders short enough to
ensure a sturdy installation. If it is necessary to extend
further, consider a different type of field-fabricated
framework that is sturdy enough for greater heights.
The inside diameter of the 4" (101.6mm) piping is
approximately 0.25" (6.35mm) greater than the
pre-installed feet on the unit. Devise a shim that will take up
the space and hold the extenders onto the feet during this
procedure. Small strips of 0.125" (3.175mm) thick
adhesive foam may be used. One or two small 1"
(25.4mm) square strips should be adequate to hold the
extender in place.

ELEVATING THE UNIT (LARGER-BASE UNITS)
Unlike the small-base units which use round feet, the
larger-base units are outfitted with elongated feet as
illustrated in figure 4. which uses a similar method for
elevating the unit height.
If additional elevation is necessary, raise the unit by
extending the length of the unit support feet. This may be
done with 2" SCH 40 female threaded adapter. The
specified coupling will fit snuggly into the recess portion of
the feet. Additional couplers can be used to make
additional adjustments to the level of the unit.
NOTE - Keep the height of extenders short enough to
ensure a sturdy installation. If it is necessary to extend
further, consider a different type of field-fabricated
framework that is sturdy enough for greater heights.

To help stabilize an outdoor unit, some installations may
require strapping the unit to the pad using brackets and
anchors commonly available in the marketplace.

Figure 7. Rooftop Application with Wind Barrier
If unit cannot be located away from prevailing winter winds,
construct a wind barrier sized at least the same height and
width as outdoor unit. Position barrier 24" (610 mm) from
the sides of the unit in direction of prevailing winds (fig. 7).
IMPORTANT! Do not allow panels to hang on unit by top tab.
Tab is for alignment and not designed to support weight of panel,
Panel shown slightly rotated to allow top tab to exit (or enter) top
slot for removing (or installing) panel.

ROOF MOUNTING
Install unit 6" (152 mm) above the roof surface to avoid ice
build-up around the unit. Locate the unit above a load
bearing wall or area of the roof that can adequately support
the unit, Consult local codes for rooftop applications.
If unit cannot be located away from prevailing winter winds,
construct a wind barrier sized at least the same height and
width as outdoor unit, Position barrier 24" (610 mm) from
the sides of the unit in direction of prevailing winds as

motion:
• Slightly rotate and guide the lipof top tab inward (figure
8, Details A and C); then upward into the top slot of the
hinge corner post,
• Rotate panel to vertical to fully engage all tabs,
• Holding the panel's hinged side firmly in place, close

In the U.S.A., wiring must conform with current local codes
and the current National Electric Code (NEC). In Canada,
wiring must conform with current local codes and the current
Canadian Electrical Code (CEC).
Refer to the furnace or blower coil installation instructions
for additional wiring application diagrams and refer to unit
nameplate for minimum circuit ampacity and maximum
overcurrent protection size.
