Installation Clearances

Special consideration must be given to location of the con-
densing 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 unob-
structed; however, if vertical conditions require placement be-
neath 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 deter-
mining final clearances.

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 installations are strongly discouraged.

Minimum Airflow  C learance

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 con-
sideration is given to the weather-tight integrity of the roof. Since

the unit can vibrate during operation, sound vibration transmis-
sion should be considered when installing the unit. Vibration
absorbing pads or springs can be installed between the con-
densing 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.

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.

•  

•  

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 re-

    frigerant.
•   Never add anything other than R-22 to an R-22 cy-
    linder 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 cy-
    linder as a platform or a roller.
