4.2 Choosing a Location

4.2.1 Allowable Clearances

12" to side intake louvers
24" to service access panels
60" vertical for fan discharge
If space limitations exist, the following clearances
will have minimal impact to capacity and efficiency
and are permitted:
Single-Unit Applications: Minimum of 6" to side
intake louvers. Do not reduce the 60" [152.4 cm]
for fan discharge or the 24" [61.0 cm] service
clearances.
Multiple-Unit Applications: For units positioned
next to each other, a minimum of 6" [15.2 cm]
clearance between units is recommended for 2 ton
models and 9" [22.9 cm] for 3 ton to 5 ton models.
Do not reduce the 60" [152.4 cm] for fan discharge
or the 24" [61.0 cm] service clearances.
IMPORTANT:
national building codes and ordinances for special
installation requirements. Following location
information will provide longer life and simplified
servicing of the outdoor heat pump.
NOTICE:
These units must be installed
outdoors. No ductwork can be attached, or
other modifications made, to the discharge grille.
Modifications will affect performance or operation.

4.2.2 Operational Issues
IMPORTANT:
in a manner that will not prevent, impair, or
compromise the performance of other equipment
installed in proximity to the unit. Maintain all
required minimum distances to gas and electric
meters, dryer vents, and exhaust and inlet
openings. In the absence of national codes or
manufacturers' recommendations, local code
recommendations and requirements will take
precedence.
• Refrigerant piping and wiring should be properly
sized and kept as short as possible to avoid
capacity losses and increased operating costs.
• Locate the unit where water runoff will not create
a problem with the equipment. Position the unit
away from the drip edge of the roof whenever
possible. Units are weatherized, but can be
affected by the following:
• Water pouring into the unit from the junction
of rooflines, without protective guttering. Large
volumes of water entering the heat pump while
in operation can impact fan blade or motor life,
and coil damage may occur to a heat pump
if moisture cannot drain from the unit under
freezing conditions.
• Freezing moisture or sleeting conditions can
cause the cabinet to ice-over prematurely and
prevent heat pump operation, requiring backup
heat, which generally results in less economical
operation It is highly recommended to switch
the EcoNet™ Control Center or thermostat to
the "Emergency Heat" mode during freezing rain
or sleeting conditions to prevent damage to the
outdoor coil from ice accumulating on the fan
blade.
• Closely follow the clearance recommendations
on page 8.
• 24" [61.0 cm] to the service panel access
• 60" [152.4 cm] above heat pump fan
discharge (unit top) to prevent recirculation
• 6" [15.2 cm] to heat pump coil grille air inlets
with 12" [30.5 cm] minimum recommended
