FNS Plus Vertical Grid D.E. Filter Owner's Manual ...

1 Rev. H 4-2-081P/N 190033 FNS Plus Vertical Grid Filter Owner's ManualSECTION INSTALLATIONA. GENERAL Filter should be mounted on a level concrete slab. Positionthe Filter so that instructions, warnings and the pressure gaugeare visible to the operator. It also should be positioned so thatthe piping connections, control valve and drain port areconvenient and accessible for servicing and electrical controls ( , on/off switches, timers, controlsystems, etc.) at least five (5) feet from the Filter . This willallow you enough room to stand clear of the Filter duringsystem start sufficient clearance around the Filter to permit visualverification that the clamp is properly installed around the tankflanges, see Figure the clamp with a mallet or similar tool to ensure uniformloading during clamp SAFETY INSTRUCTIONSREAD AND FOLLOW ALL INSTRUCTIONSSAVE THESE INSTRUCTIONST able of ContentsSECTION 1 SECTION II.

H sufficient space above the Filter to remove the Filter lid for cleaning and servicing. This distance will vary with the model offilter you are using. See Table 1 for the required Vertical the Filter to safely direct water drainage. Rotate the High Flow Manual air relief valve to safely direct purged air orwater. Water discharged from an improperly positioned Filter or valve can create an electrical hazard as well as Filter requires one of the following Pentair Water Pooland Spa accessories which must be purchased union all plumbing connections in accordance with localplumbing and building codes.

4 Filter plumbing connectionsare provided with an O-ring seal. To avoid damage to theO-rings, use only a silicone base lubricant on the O-rings. Do not use pipe joint compound, glue or solvent on the the plug from the top of the Filter lid and install the pressure gauge before maximum working pressure of this Filter is 50 psi. Never subject this Filter to pressure in excess of this amount - even whenconducting hydrostatic pressure tests. Pressures above 50 psi can cause the lid to be blown off, which can result in severe injury,death or property performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and plumbingsystem, ensure that the maximum pressure that the filtration system will be subjected to DOES NOT EXCEED THEMAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM.

5 In mostcases, the maximum working pressure will be stated on each component of the doubt exists as to the pressure to which the system will be subjected, install an ASME approved automatic Pressure Reliefor Pressure Regulator in the circulation system for the lowest working pressure of any of the components in the OPERATIONA. GENERAL Filter operates under pressure. When clamped properly and operated without air in the water system, this Filter willoperate in a safe maximum working pressure of this Filter is 50 psi.

6 Never subject this Filter to pressure in excess of this amount - even whenconducting hydrostatic pressure tests. Pressures above 50 psi can cause the lid to be blown off, which can result in severeinjury, death or property performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and plumbingsystem, ensure that the Maximum Pressure that the filtration system will be subjected to DOES NOT EXCEED THEMAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM.

7 In mostcases, the maximum working pressure will be stated on each component of the doubt exists as to the pressure to which the system will be subjected, install an ASME approved automatic PressureRelief or Pressure Regulator in the circulation system for the lowest working pressure of any of the components in pressure gauge is the primary indicator of how the Filter is operating. Maintain your pressure gauge in good working operate Filter in excess of three (3) minutes without use of diatomaceous earth. Diatomaceous earth is the substancethat filters the water, the Filter cloth merely supports the diatomaceous earth.

Position the Filter and High Flow Manual air relief valve to safely direct water drainageand purged air or water. Water discharged from an improperly positioned Filter or valve can create an electrical hazard that cancause severe personal injury as well as damage H 4-2-083P/N 190033B. CLAMP INSTALLATION instructions MUST BE FOLLOWED EXACTLY to prevent the lid from blowing off during system restart or the following steps before working on any part of the circulating system, , clamp, pump, Filter , valve(s), the pump off and shut off any automatic controls to ensure that the system is not inadvertently started the High Flow Manual air relief valve until it snaps into the full open position (this only requires a quarter turncounter clockwise).

9 Until all pressure is relieved. Never attempt to assemble, disassemble or adjust the Filter clamp while there isany pressure in the certain the O-ring is in position in the lower tank half. Press the Filter lid over the lower tank half sandwiching the O-ringin the ends of the Filter clamp apart, position the center segment of the Filter clamp over both upper and lower tankflanges. Bring the ends of the Filter clamp together, while inserting the T-Bolt into the trunnion; see Figure Figure 2 as a guide - place washer (large ) and the tension-indicating spring on the barrel nut.

10 Place the secondwasher (small ) on the T-Bolt. Hand-tighten nut. Recheck filterclamp for proper seating on tank to tighten nut using a 7/8 in. wrench. Then tap around theoutside of the Filter clamp with a mallet (or similar tool) to ensureuniform loading and proper seating of the clamp. Continue tappingand tightening until the spring coils touch each other. Do nottighten beyond this the instructions in Section C, SYSTEM RESTARTINSTRUCTIONS, which spring coils should be checked at least once per month toensure that they continue to touch each other, indicating that theclamp is under sufficient tension.
