•
Locate unit away from overhanging roof lines which
would allow water or ice to drop on, or in front of, coil
or into unit.
When outdoor unit is connected to factory-approved indoor
unit, outdoor unit contains system refrigerant charge for
operation with matching indoor unit when connected by 15
ft. of field-supplied tubing. For proper unit operation, check
refrigerant charge using charging information located on
control box cover.
Outdoor Section
Zoning ordinances may govern the minimum distance the
condensing unit can be installed from the property line.
Install on a Solid, Level Mounting Pad
The outdoor section is to be installed on a solid foundation.
This foundation should extend a minimum of 2” (inches)
beyond the sides of the outdoor section. To reduce the
possibility of noise transmission, the foundation slab
should NOT be in contact with or be an integral part of the
building foundation. See Figure 2.
If conditions or local codes require the unit be attached to
pad or mounting frame, tie down bolts should be used and
secured to unit base pan.

Table 1.
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
who have jurisdiction before installation.
Installation
NOTE:
In some cases, noise in the living area has been
traced to gas pulsations from improper installation of
equipment.
•
Locate unit away from windows, patios, decks, etc.
where unit operation sounds may disturb customer.
•
Leave some slack between structure and unit to
absorb vibration.
•
Place a sound-absorbing material, such as Isomode,
under the unit if it will be installed in a location or
position that will transmit sound or vibration to the
living area or adjacent buildings.
•
In heavy snow areas, do not locate the unit where
drifting snow will occur. The unit base should be
elevated above the depth of average snows.
NOTE:
Elevation of the unit may be accomplished
by constructing a frame using suitable materials. If a
support frame is constructed, it must not block drain
holes in unit base.
•
When installed in areas where low ambient
temperatures exist, locate unit so winter prevailing
winds do not blow directly into outdoor coil.
