Another important consideration in selecting a location for the
unit(s) is the angle to obstructions.  Either side adjacent the valves
can be placed toward the structure provided the side away from
the structure maintains minimum service clearance.  Corner in-
stallations 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 foun-
dation 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 consider-
ation 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 absorb-
ing pads or springs can be installed between the condensing unit
legs or frame and the roof mounting assembly to reduce noise
vibration.

NOTE: These units require special location consideration in areas
of heavy snow accumulation and/or areas with prolonged
continuous subfreezing temperatures. Heat pump unit bases have
cutouts under the outdoor coil that permit drainage of frost
accumulation. Situate the unit to permit free unobstructed drainage
of the defrost water and ice.

In more severe weather locations, it is recommended that the unit
be elevated to allow unobstructed drainage and air flow. The
following elevation minimums are recommended:

Safe Refrigerant Handling

While these items will not cover every conceivable situation, they
should serve as a useful guide.

To avoid possible injury, explosion or death, practice safe
handling of refrigerants.

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.

•  

•   

To avoid possible explosion, use only returnable (not disposable)

service cylinders when removing refrigerant from a system.

 •  Ensure the cylinder is free of damage which could lead to a

     leak or explosion.

•   Ensure the hydrostatic test date does not exceed 5 years.

•   Ensure the pressure rating meets or exceeds 400 lbs.

When in doubt, do not use cylinder.
