Installation
System Pressure
The maximum fluid working pressure of this surge
suppressor is 100 psi (0.7 MPa, 7 bar) at 100 psi
(0.7 MPa, 7 bar) incoming air pressure. Never exceed
100 psi (0.7 MPa, 7 bar) fluid or air pressure to the
surge suppressor. Do not exceed the maximum
working pressure of any component or accessory used
in the system.
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of serious bodily injury, including
splashing fluid or solvent in the eyes or on the skin,
always follow this procedure before you check,
adjust, clean, or repair any part of the system.
1. Close the air regulator by turning counterclockwise
as far as possible.
2. Disconnect the air supply line to the surge
suppressor.
3. Open the dispensing valve, if used.
4. Open the fluid drain valve to relieve all fluid
pressure; have a container ready to catch the
drainage.
Fluid Compatibility
Be sure all fluids and solvents used are chemically
compatible with the wetted parts and non-wetted parts
shown in the Technical Data section on page 16.
Failure of the diaphragm may cause non-wetted parts
to be exposed to fluid. Always read the fluid and
solvent manufacturer’s literature before using them
with this equipment.
Grounding
WARNING
This equipment must be grounded. Read and
carefully follow the text of FIRE AND EXPLOSION
HAZARD on page 3 before operating the surge
suppressor.
Static electricity is created by the fluid flowing through
the pump and hose. If the equipment is not properly
grounded, sparking may occur, and the system may
become hazardous. Sparks can ignite fumes from
solvents and the fluid being pumped, dust particles,
and other flammable substances, whether you are
pumping indoors or outdoors, and can cause a fire or
explosion and serious bodily injury and property
damage.
If you experience any static sparking or even a slight
shock while using this equipment, stop pumping
immediately. Do not use the system again until the
problem has been identified and corrected.
To reduce the risk of static sparking, ground the pump,
surge suppressor, and all other equipment used or
located in the pumping area. Check your local
electrical code for detailed grounding instructions for
your area and type of equipment. Ground all of this
equipment:
D Pump: See your separate pump instruction
manual.
D Surge suppressor: Secure a ground wire (Y) to the
surge suppressor with the grounding screw (Z)
located on the side of the housing. See Fig. 1.
Connect the clamp end of the ground wire to a true
earth ground. To order a ground wire and clamp,
order Part No. 208950.
D Air and fluid hoses: Use only grounded hoses with
a maximum of 500 ft (150 m) combined hose length
to ensure grounding continuity.
D Air compressor: Follow the manufacturer’s
recommendations.
D All solvent pails used when flushing: Follow the
local code. Use only metal pails, which are
conductive. Do not place the pail on a
nonconductive surface, such as paper or
cardboard, which interrupts the grounding
continuity.
D Fluid supply container: Follow the local code.
