Setting Outdoor Unit
OUTDOOR UNIT POSITIONING CONSIDERATIONS
(AIR CONDITIONER OR HEAT PUMP)
Consider the following when positioning the unit:
* Some localities are adopting sound ordinances based
on the unit's sound level registered from the adjacent
property, not from the property where the unit is
installed. Install the unit as far as possible from the
property line.
* When possible, do not install the unit directly outside a
window. Glass has a very high level of sound
transmission. For proper placement of unit in relation
to a window see the provided illustration in figure 2.
* 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.
* Install the unit high enough above the ground or roof to
allow adequate drainage of defrost water and prevent
ice or snow build-up (required for heat pumps).
* In heavy snow areas, do not locate the unit where
drifting will occur. The unit base should be elevated
above the depth of average snows.
* When installed in areas where low ambient
temperatures exist, locate unit so winter prevailing
winds do not blow directly onto outdoor unit.
* Locate unit away from overhanging roof lines which
would allow water or ice to drop on, or in front of, coil
or into unit.
CONDENSATE DRAINAGE REQUIREMENT
(HEAT PUMP ONLY)
Condensate formed during the heating and defrost
processes must be drained from heat pump units. Drain
holes are provided in the base of the units to ensure proper
drainage. Heat pumps must be raised when installed on a
concrete pad or the ground to allow drainage to occur. If the
heat pump unit is installed on a wall mounting bracket,
insert the provided drain connector into one of the 1 inch
(25mm) drain holes and attached a field-provided insulated
drain hose to the connector. Use the provided rubber plugs
to cover any unused drain holes (figure 3).

NOTICE
Roof Damage!
This system contains both refrigerant and oil. Some
rubber roofing material may absorb oil. This will cause
the rubber to swell when it comes into contact with oil.
The rubber will then bubble and could cause leaks.
Protect the roof surface to avoid exposure to refrigerant
and oil during service and installation. Failure to follow
this notice could result in damage to roof surface.
SLAB OR ROOF MOUNTING
Install the unit a minimum of 4 inches (102 mm) above the
roof or ground surface to avoid ice build-up around the unit.
Locate the unit above a load bearing wall or area of the roof
that can adequately support the unit. Consult local codes
for rooftop applications (figure 4).

BUILDING STRUCTURE
Install unit level or maintain slope tolerance of 2
degrees (or 2 inches per 5 feet [50 mm per 1.5 m])
away from building structure.

SECURING OUTDOOR UNIT TO SLAB OR FRAME
If the outdoor unit is installed on a field-provided slab or
frame, use lag bolts or equivalent to secure the outdoor unit
to the slab or frame (figure 5).
