GSXH5 Installation Manual

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.
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
The specied dimensions meet
requirements for air circulation only. Consult all appropriate
regulatory codes prior to determining nal 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 oor level or on at
roofs. At ground oor 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 sucient to
support the unit. A concrete slab raised above ground level
provides a suitable base.
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.
While these items will not cover every conceivable
situation, they should serve as a useful guide.
