CAUTION: Do not over-lubricate air supply —
excess lubrication will reduce performance.
CAUTION: Do not exceed 8.6 bar (125 psig) air
supply pressure.
CAUTION: When choosing dampener materials,
be sure to check the temperature limits for
all wetted components. Example: Viton®
has a maximum limit of 177°C (350°F) but
polypropylene has a maximum limit of only 79°C
(175°F).
CAUTION: Maximum temperature limits are
based upon mechanical stress only. Certain
chemicals will significantly reduce maximum
safe operating temperatures. Consult Chemical
Resistance Guide (E4) for chemical compatibility
and temperature limits.

NOTE: Not all materials are available for all
models. Refer to Section 2 for material options
for your pump.
WARNING: Prevent static sparking. If static
sparking occurs, fire or explosion could result.
Dampener, pump, valves and containers must
be grounded to a proper grounding point
when handling flammable fluids and whenever
discharge of static electricity is a hazard.
CAUTION: The process fluid and cleaning fluids
must be chemically compatible with all wetted
dampener components. Consult Chemical
Resistance Guide (E4).
CAUTION: Dampener(s) should be thoroughly
flushed before installing into process lines.
FDA- and USDA- approved dampeners should be
cleaned and/ or sanitized before being used.
CAUTION: Always wear safety glasses when
operating dampener. If diaphragm rupture
occurs, process fluid may be forced out air
exhaust.
CAUTION: Before any maintenance or repair
is attempted, the compressed air line to the
dampener and pump should be disconnected
and all air pressure allowed to bleed from the
system. Disconnect all intake, discharge and air
lines. Drain the dampener by allowing any fluid
to flow into a suitable container.
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to dampener to make sure all
pipeline debris is clear. Use an in-line air filter.
A 5μ (micron) air filter is recommended.
CAUTION: Dampeners cannot be used in
submersible applications.
CAUTION: Tighten all hardware prior to
installation.
CAUTION: ATEX products have been assessed
for use in potentially explosive atmospheres in
accordance with the European Directive 94/9/
EC (ATEX 95). Users of ATEX products must be
familiar with ATEX requirements and follow
all safety guidelines. (Refer to Wilden Safety
Supplement WIL-18510-E).
