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: . Pump: See your separate pump instruction manual. . 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. . Air and fluid hoses: Use only grounded hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. . Air compressor: Follow the manufacturer’s recommendations. . 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. . Fluid supply container: Follow the local code. Z Y Fig. 1 . .

Installation General Information The surge suppressor uses air pressure and a diaphragm to maintain a consistent fluid outlet pressure from a double diaphragm or low-pressure reciprocating pump. During normal flow, the suppressor air pressure and fluid pressure are in equilibrium. A sharp increase in fluid pressure causes the air inlet port to open, increasing air pressure on the diaphragm and returning the system to equilibrium. Conversely, a sharp decrease in fluid pressure causes the air exhaust port to open, decreasing air pressure on the diaphragm and allowing the system to return to equilibrium. Installation 1. Read this entire manual before installing or operating the surge suppressor. 2. The surge suppressor fluid inlet must be connected to the pump’s fluid outlet. If the pump is aluminum or steel, the surge suppressor may be plumbed directly to the outlet, using 3/4 npt fittings. If the pump is acetal or polypropylene, place the surge suppressor on the floor or some other solid, level surface near the pump, and connect the surge suppressor inlet to the pump outlet with a 3/4” ID hose and 3/4 npt fittings. CAUTION Do not plumb the surge suppressor directly onto the fluid outlet of an acetal or polypropylene pump. Those pumps cannot support the weight of the suppressor and will suffer damage or rupture. 3. Connect an air line from the pump’s air regulator to the air inlet of the surge suppressor. In systems using a 1:1 ratio pump, the air pressure supplied to the suppressor will be the same as that supplied to the pump. 4. Use a compatible, liquid thread sealant on all male threads. Tighten all connections firmly to avoid air or fluid leaks. Air Exhaust Ventilation WARNING Be sure to read TOXIC FLUID HAZARD and FIRE AND EXPLOSION HAZARD on page 3, before operating this equipment. Be sure the system is properly ventilated for your type of installation. When pumping flammable or hazardous fluids, you must vent the surge suppressor exhaust air to a safe place, away from people, animals, food handling areas, and all sources of ignition. If the diaphragm ruptures, the fluid will be exhausted along with the air. Place a container at the end of the air exhaust line to catch the fluid. See Detail A on page 5. The minimum size for the air exhaust hose is 3/8 in. (10 mm) ID x 15 ft (4.6 m). If a longer hose is required, use a larger diameter hose. 1. Remove the muffler from the surge suppressor exhaust port. Install an exhaust hose in the exhaust port, and connect the muffler to the other end of the hose. Avoid sharp bends or kinks in the hose. See Detail A on page 5. 2. Place a container at the end of the air exhaust line to catch fluid in case the diaphragm ruptures. WARNING Never operate the surge supp...
