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
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:
DPump: See your separate pump instruction manual.
DSurge 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.
DAir and fluid hoses: Use only grounded hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity.
DAir compressor: Follow the manufacturer’s recommendations.
DAll 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.
DFluid supply container: Follow the local code.
