IMPORTANT: This product has been designed and
manufactured to meet ENERGY STAR criteria for energy
efficiency when matched with appropriate coil components.
However, proper refrigerant charge and proper air flow
are critical to achieve rated capacity and efficiency.
Installation of this product should follow the manufacturer's
refrigerant charging and air flow instructions. Failure to
confirm proper charge and airflow may reduce energy
efficiency and shorten equipment life.
When servicing or repairing HVAC components, ensure
the fasteners are appropriately tightened. Table 1 shows
torque values for fasteners.

Inspection of Shipment
Upon receipt of equipment, carefully inspect it for possible
shipping damage. If damage is found, it should be noted
on the carrier's freight bill. Take special care to examine
the unit inside the carton if the carton is damaged. Any

last carrier immediately, preferably in writing, and should
include a request for inspection by the carrier's agent.
If any damages are discovered and reported to the carrier
DO NOT INSTALL THE UNIT, as claim may be denied.
Check the unit rating plate to confirm specifications are as
ordered.

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.
•
Install the unit high enough above the ground or roof to
allow adequate drainage of defrost water and prevent
ice buildup.
•
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
temperatures exist, locate unit so winter prevailing
winds do not blow directly into outdoor coil.
•
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 1.
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.
