WaRnIng
Personal injury, property damage,
equipment damage or leakage due to
escaping gas or bursting of pressure-
containing parts may result if this
regulator is overpressured or is installed
where service conditions could exceed
the limits given in Specifications
section, Tables 1 through 3 or where
conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate
code, regulation or standard) to prevent
service conditions from exceeding
those limits.
additionally, physical damage to the
regulator could cause personal injury or
property damage due to escaping gas.
To avoid such injury or damage, install
the regulator in a safe location.
Before installing, inspect the unit for any damage and
any foreign material. The regulator or relief valve may
be mounted in any position, however, ensure that the
flow direction corresponds with the direction of the
arrow on the nameplate. Apply a good grade of pipe
compound to the male threads of the pipeline.
