DANGER
The refrigeration circuits are high pressure systems.
Hazards exist that could result in personal injury or death. It
is therefore required that the removal and installation of this
scroll compressor be performed by a technician qualified in
R-410A refrigerant. See Hazard Levels, page 2.
DANGER
Never use oxygen to pressurize a refrigeration system. Oxygen
can explode on contact with oil and could result in personal injury
or death. When using high pressure gas such as nitrogen for
this purpose, ALWAYS USE A PRESSURE REGULATOR that can
control the pressure down to 1 or 2 psig. Failure to use a regulator
will result in extremely high pressure which could exceed the
burst pressure of the compressor or other system components
and result in personal injury or death. See Hazard Levels, page 2.
