Heat Pump Installation and User’s Guide
5
Clearances
All criteria given in the following sections refl ect minimum clearances. However, each installation must
also be evaluated, taking into account the prevailing local conditions such as proximity and height of
walls, and proximity to public access areas.
The heat pump must be placed to provide clearances on all sides for maintenance and inspection.
1. At least 24 in. [610 mm] access must be available in the front and 12 in. [30.5 mm] on all the other
sides of the heat pump for service and proper air fl ow, see
Figure 2
.
2. If the heat pump is to be installed under a cover or under a vertical overhang, the unit must have a
minimum of fi ve (5) feet [1520 mm] clearance from the top of the heat pump.
3. Install a minimum of fi ve (5) feet [1.52 m] from the inside wall of the pool or spa unless the heat
pump is separated from the pool or spa by a fi ve (5) foot high solid fence or other permanent barrier.
Canadian installations require a minimum of three (3) meters from pool water.
Roof Run-off
Make sure the heat pump is not located where large amounts of water may run-off from a roof into
the unit. Sharp sloping roofs without gutters will allow massive amounts of rain water, mixed with
debris from the roof to be forced through the unit, see
Figure 2
. A gutter or down spout may be
needed to protect the heat pump.
Equipment Pad
Place the heat pump on a fl at slightly pitched surface, such as a concrete or fabricated slab (pad). This
allows proper drainage of condensation and rain water from the base of the unit. If possible, the pad
should be placed at the same level or slightly higher than the fi lter system equipment pad.
NOTE: Ensure that the pad is pitched not more than 1/4 in. per foot toward the compressor end
(front) of the heat pump. Pitch slab from back to front 1/4 in. per foot maximum and level from
side to side.
