6. Air Exhaust Ventilation A WARNING Be sure to read TOXIC FLUID HAZARD and FIRE AND EXPLOSION HAZARD on page 3 before operating this equipment 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 A 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 s
