If the unit is exposed to prevailing winds:
Install the unit so that air outlet is at a 90° angle to
the direction of the wind. If needed, obtain wind
baffles from your distributor to protect the unit from
extremely heavy winds. See 4.2 and Fig. 4.3.

The outdoor unit can be anchored to the ground or to a wall-

For cooling only units, if the unit is installed on the
ground or on a concrete mounting platform, do the
following:
1. Mark the positions for 4 expansion bolts required.
2. Pre-drill holes for expansion bolts.
3. Clean concrete dust away from holes.
4. Place a nut on the end of each expansion bolt.
5. Hammer expansion bolts into the pre-drilled holes.
6. Remove the nuts from the expansion bolts, and place
outdoor unit on bolts.
7. Put washer on each expansion bolt, then
replace the nuts.
8. Using a wrench, tighten each unit until snug.
9. Heat pumps must be elevated off grade / roof
minimum 18” to ensure proper winter operation
during defrost cycle.
Caution: Heat pumps must be installed on a
properly designed stand and have minimum
18” clearance from normal snow levels
in the
area.
Systems being installed in close proximity to
salt water or other corrosive substances must
be specially coated to prevent corrosion.
