•
Sudden and irreversible tissue damage can result from freezing.
Wear gloves and face protector or safety glasses in any situation
where skin or eye contact with refrigerant is possible.
•
Heat may cause the refrigerant to decompose and release irritating,
toxic, and corrosive gases. Prevent contact of refrigerant with flame
or hot surfaces.

caustic. Wear gloves and a face protector or safety glasses in any
situation where skin or eye contact is possible. If oil does contact

a. Installation.
CAUTION
Using excessive force when opening or closing valves can cause
damage to the valve seats.
NOTE
The compressor shut off valves can be adjusted to three positions, fully
closed to block the refrigerant tubes and isolate the compressor and
service port, fully open to allow flow from piping to compressor but not
the service port, and cracked (one turn closed from fully open) to allow
flow from piping to compressor and service port on valve.
(1) Remove two shut off valve caps and turn the shut off valves fully counterclockwise to backseat them.
