WARNING
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.
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
having jurisdiction 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
Part Recommended Torque
Service valve cap 8 ft.- lb. 11 NM
Sheet metal screws 16 in.- lb. 2 NM
Machine screws #8 16 in.- lb. 2 NM
Compressor bolts 90 in.- lb. 10 NM
Gauge port seal cap 8 ft.- lb. 11 NM
CAUTION
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
for installation clearances.
1. Place a sound-absorbing material, such as Isomode,
under the unit if it will be installed in a location or
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.
NOTES:
Service clearance of 30 in, (762 mm) must be maintained on
one of the sides adjacent to the control box.
Clearance to one of the other three sides must be 36 in. (914
mm)
Clearance to one of the remaining two sides may be 12 in. (305
mm) and the final side may be 6 in. (152 mm),
A clearance of 24 in, (610 mm) must be maintained between
two units.
48 in. (1219 mm) clearance required on top of unit,
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 on page
4.
INSTALL UNIT LEVEL OR, IF ON A SLOPE, MAINTAIN SLOPE
TOLERANCE OF 2 DEGREES (OR 2 INCHES PER 5 FEET
[50 MM PER 1.5 M]) AWAY FROM BUILDING STRUCTURE.
