Outdoor units are approved for operation above 55°F in
cooling mode. Operation below 55°F requires the use of an
approved low ambient kit. Note: LAKT01 Low ambient kit
cannot be used with outdoor units containing ECM motors.
Damage to the unit caused by operating the unit in a
structure that is not complete (either as part of new
construction or renovation) is not covered under the
warranty.
INSTALLATION CLEARANCES
Special consideration must be given to location of the
condensing unit(s) in regard to structures, obstructions,
other units, and any/all other factors that may interfere with
air circulation. Where possible, the top of the unit should
be completely unobstructed; however, if vertical conditions
require placement beneath an obstruction
there should
be a minimum of 60 inches between the top of the unit
and the obstruction(s).
The specified dimensions meet
requirements for air circulation only. Consult all appropriate
regulatory codes prior to determining final clearances.
Another important consideration in selecting a location for
the unit(s) is the angle to obstructions. Either side adjacent
the valves be placed toward the structure provided the
side away from the structure maintains minimum service
clearance. Corner installations are strongly discouraged.

Minimum Airflow Clearance
This unit can be located at ground floor level or on flat
roofs. At ground floor level, the unit must be on a solid,
level foundation that will not shift or settle. To reduce the
possibility of sound transmission, the foundation slab
should not be in contact with or be an integral part of the
building foundation. Ensure the foundation is sufficient to
support the unit. A concrete slab raised above ground level
provides a suitable base.
ROOFTOP INSTALLATIONS
If it is necessary to install this unit on a roof structure,
ensure the roof structure can support the weight and that
proper consideration is given to the weather-tight integrity
of the roof. Since the unit can vibrate during operation,
sound vibration transmission should be considered when
installing the unit. Vibration absorbing pads or springs can
be installed between the condensing unit legs or frame and
the roof mounting assembly to reduce noise vibration.
WARNING
To avoid possible injury, explosion or death, practice safe
handling of refrigerants.
SAFE REFRIGERANT HANDLING
While these items will not cover every conceivable
situation, they should serve as a useful guide.
WARNING
Refrigerants are heavier than air. They can “push out” the
oxygen in your lungs or in any enclosed space. To avoid
possible difficulty in breathing or death:
•
Never purge refrigerant into an enclosed room or
space. By law, all refrigerants must be reclaimed.
•
If an indoor leak is suspected, thoroughly ventilate the
area before beginning work.
•
Liquid refrigerant can be very cold. To avoid possible
frostbite or blindness, avoid contact and wear gloves
and goggles. If liquid refrigerant does contact your
skin or eyes, seek medical help immediately.
•
Always follow EPA regulations. Never burn refrigerant,
as poisonous gas will be produced.
WARNING
To avoid possible explosion:
•
Never apply flame or steam to a refrigerant cylinder. If
you must heat a cylinder for faster charging, partially
immerse it in warm water.
•
Never fill a cylinder more than 80% full of liquid
refrigerant.
•
Never add anything other than R-22 to an R-22 cylinder
or R-410A to an R-410A cylinder. The service equipment
used must be listed or certified for the type of
refrigerant used.
•
Store cylinders in a cool, dry place. Never use a
cylinder as a platform or a roller.
