Use field-supplied spreader bars when lifting the unit to mini-
mize the possibility of lifting cable/straps damage. To protect
the cabinet louvers, use protective material such as plywood
behind the cable/straps. Arrange the straps to form a central
suspension point. NOTE: When raising and setting the unit,
observe all safety rules. Remove shipping skid and all protec-
tion and lifting material after the unit is in place.
Safe Refrigerant Handling
While these items will not cover every conceivable situation,
they should serve as a useful guide.
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, throughly 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 refrig-
erant, 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 re-
frigerant.
• Never add anything other than R-22 to an R-22 cy-
linder. 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.

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.

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. The foundation
slab should be a minimum of 6” wider than the unit in all direc-
tions. Ensure the foundation is sufficient to support the unit. A
concrete slab raised above ground level provides a suitable
base.
The selected site should be no greater than 50’ below or 70’
above the evaporator section. For optimum performance, the
minimum length interconnecting tubing is preferred. When pos-
sible minimize the amount of bends and turns.
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.
Rigging
To avoid possible injury or death, all panels must be
in position and secured before lifting this equipment
