WARNING
Personal injury or equipment damage,
due to bursting of pressure-containing
parts may result if this regulator is
overpressured or is installed where
service conditions could exceed the limits
given in the characteristics section and
on the appropriate nameplate or where
conditions exceed any rating of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits. Also, be sure
that installation is in compliance with all
applicable code and regulations.
Physical damage to the regulator can
break the pilot off the main valve, causing
personal injury and property damage due
to bursting of pressure-containing parts.
To avoid such injury and damage, install
the regulator in a safe location.
