WARNING
ELECTRICAL SHOCK HAZARD
Failure to turn off the main (remote) electrical dis-
connect device could result in personal injury or
death.
Before installing, modifying or servicing system,
turn OFF the main (remote) electrical disconnect
device. There may be more than one disconnect
device.
Check
local codes
for regulations
concerning
zoning,
noise, platforms, and other issues.
Locate
unit
away
from
fresh
air
intakes,
vents,
or
bedroom
windows.
Noise may carry into the openings
and disturb people inside.
Locate unit in a well drained area, or support unit high
enough so that water runoff will not enter the unit.
Locate unit away from areas where heat, lint, or exhaust
fumes will be discharged onto unit (as from dryer vents).
CLEARANCES
Locate unit away from recessed or confined areas where
recirculation
of
discharge
air
may
occur
(refer
to
CLEARANCES section of this document).
Roof-top installation is acceptable providing the roof will
support
the
unit
and
provisions
are
made
for water
drainage and noise/vibration dampening.
NOTE:
Roof mounted units exposed to wind may require
wind
baffles.
Consult
the
manufacturer
for additional
information.
Nominal
minimum
clearances
are
48
inches
(1.2m)
above unit for discharge air and 18 inches (457mm) on
each side of the coil for intake air. Clearance on any one
side of the coil (normally between unit and structure) may
be
reduced
to 6 inches
(152mm).
Nominal
minimum
clearances are based on a solid parallel object such as a
wall or roof overhang.
The clearance may be reduced for a single object with
small surface area, such as the end of a wall, outside
corner of a wall, fence section, post, etc. As a general
rule, the minimum clearance from the unit should equal
the width of the object. For example, a 6 inch (152mm)
fence post should be a minimum
of 6 inches (152mm)
from the unit.
Do not install unit under roof overhangs unless gutters are
present.
A
minimum
vertical
clearance
of 48
inches
(1.2m) is required to the overhang.
Inside corner locations on single story structures require
evaluation.
Large
overhanging
soffits
may
cause
air
recirculation in a corner area even though recommended
minimum clearances are maintained. As a guide, locate
the unit far enough out so that half of the discharge grille is
out from under the soffit.
When placing two or more units side-by-side, provide a
minimum of 18 inches (457mm) between units.
Provide
minimum
service
clearance
of
24
inches
(610mm) from control box corner and side service panel.
Refer to Figure 1.
