General Safety
DO NOT misuse dampener, including but not limited
to over-pressurization, modification of parts, using
incompatible chemicals, or operating with worn or
damaged parts. DO NOT use any gases other than
compressed air or clean dry Nitrogen to charge
dampener. DO NOT USE OXYGEN. Any misuse
could result in serious bodily injury, death, fire,
explosion or property damage.
Over-Pressurization
Never exceed the maximum pressure rating for the
dampener model being used.
working pressure (MAWP) is specified on dampener
serial tag or marked on dampener.
allowable working pressure (MAWP) is rated at 70°F
(21°C).
Temperature Limits
DO NOT exceed the operating temperature limits for
the body and/or elastomer materials being used.
Excessive temperature will result in dampener
failure.
For temperature limits, refer to the
"Temperature
Limits"
Temperature limits are stated at zero psi/bar.
Installation and Start-Up Hazards
Install dampener before charging or pressurizing.
DO NOT start system or assembly without first
charging or pressurizing dampener.
charge may result in damage to the elastomeric
bladder or PTFE bellows.
GENERAL I
NFORMATION
For safe and satisfactory operation of dampener, read all safety warnings and caution statements, and
this complete Manual before installation, startup, operation or maintenance.
DO NOT use Oxygen to charge dampener.
Use compressed air or clean dry Nitrogen
only.
DO NOT exceed maximum allowable working
pressure (MAWP) specified on dampener serial
tag or marked on dampener.
Turn pump off and remove all pressure from
system prior to dampener installation.
Always
wear
appropriate safety equipment when installing,
charging or repairing dampener.

Temperature & Pressure Hazard
Temperature and pressure reduce the strength and

PTFE.
Charging / Pressurization
Charge or pressurize dampener with compressed air
or clean dry Nitrogen only. DO NOT USE OXYGEN.

NSTALLATION
Danger of static spark! Grounding precautions
must be considered when dampener is used in
flammable or explosive environments.
ATEX Models must be grounded (earthed)
before operation.
DO NOT operate a dampener that is leaking,
damaged, corroded or otherwise unable to
contain internal fluid, air or gas pressure.
