TWO-STAGE REGULATOR REPAIR KIT INSTRUCTIONS
Important: Any maintenance, service or repair
should be performed by trained and experi-
enced service technicians. Proper tools and
equipment should be used to prevent injury to
the servicing technician, property or system
components. Service repairs should always be
performed in a safe environment and the tech-
nician should always wear protective clothing
to prevent injury.
The IMPCO PPI-16 repair kit instructions will
provide the technician information to success-
fully repair the Model L regulator. Always in-
spect the major casting pieces for damage,
corrosion or cracks before attempting a service
repair. Be sure the repair kit part number you
are using is correct for the regulator being ser-
viced. Diaphragms are color coded and have
different performance characteristics:
BLACK: Hydrin diaphragm material is the
standard material and is well suited for the
most common applications.
YELLOW: Silicone diaphragm material is the
optional upgrade material that provides excel-
lent flexibility in cold weather climates and is
more resistant to chemical contamination.
