Terms and Definitions Agitation – Mechanical or manual movement to dislodge filter aid and dirt from the filter element. Bump – The process which removes the filter aid. See Agitation. Diatomite-type Filter – A pressure or vacuum type device designed to filter water through a thin layer of filter aid. -
Page 8: Safety Notices
All personnel should be thoroughly familiar with the procedures contained in this manual. It is the responsibility of the owner to ensure that the equipment is used properly and safely, strictly following the instructions contained in the manual. Safety Notices Safety notices are located throughout this manual at the point where the risk is encountered. -

Installation The filter contains internal parts that are vertically deployed. Always transport and handle the filter in an upright position. Connect air to valve. Open to pressurize. Do Not Close after Remove Plug pressurized Lifting Lugs Figure 1: Positioning and Erection of Tanks If the filter needs to be positioned horizontally for access reasons, the bump mechanism must be pressurized to a minimum of 75 PSI prior to tilting the tank. -
Page 19: Tank Leg Anchor Installation
Grounding lug mounting locations are available on each leg of the filter, each location is indicated by a sticker. Proper grounding is essential to help slow corrosion that can be caused by stray current. Refer to the Vacuum Transfer System Diagram for more information on the grounding lug locations. -
Page 20: Auxiliary Equipment Installation
With the filter tank in its installed location, use a 1/2 inch carbide drill bit and drill a 6 inch- deep hole in the floor. There should be a total of 6 1/2 inches depth from the top of leg plate. -

Page 25: Valve Installation
Valve Installation Butterfly Valves Dominion™ Butterfly Valves have nylon-coated cast aluminum bodies and nylon-coated ductile iron discs with stainless steel stems. The valves have bushings around the handle shaft to keep the water from leaking out of the shaft. As the valve ages, these bushings tend to dry out. The dryness, combined with dust and dirt, inhibits valve operation which increases the force required to turn the valve handle. -
