  • Page 4 ™ This guide provides installation and operation instructions for the Stark Series Filters. Consult Pentair Commercial Aquatics with any questions regarding this equipment. Attention Installer: This guide contains important information about the installation, operation and safe usage of this product. This information should be given to the owner and/or operator of this equipment after installation or left on or near the filter.
  • Page 5 IMPORTANT WARNING AND SAFETY INSTRUCTIONS This filter must be installed in accordance with the all applicable local codes and ordinances. Improper installation could result in death or serious injury to users, installers, or others and may also cause damage to property. Always disconnect power to the filtration system at the circuit breaker before servicing the filter.

  • Page 6: Basic Principles Of Operation

    We suggest reading this manual through once to familiarize yourself with it before proceeding with installation and operation. Again, thank you for purchasing your high rate sand filter from Pentair Commercial Aquatics. 1 Basic Principles of Operation Your high rate sand filter is designed to operate for years with a minimum amount of maintenance when installed, operated and maintained in accordance with these instructions.

  • Page 7: Backwash

    ™ The pressure in the Stark High Rate Sand Filter will increase and the flow of water through the filter will diminish as dirt accumulates in the filter. Eventually, the filter will become obstructed enough with dirt that it will become necessary to backwash the filter. Please note that a filter removes suspended matter but it does not sanitize the pool.

  • Page 8: Principles Of Operation

    1.3 Principals of Operation This section will familiarize you with how the face piping kit and valves work in order to provide a ™ means of backwashing the Stark High Rate Sand Filter. It will cover how the diaphragm valves operate, the flow of water in a single tank system in normal filtration and backwash modes, a dual tank system in normal filtration and backwash modes, and a multiple tank system in normal filtration and backwash modes.

  • Page 9: Dual Tank - Normal Filtration

    1.3.4 Dual Tank - Normal Filtration During normal filtration in a dual tank system, water is split between the two tanks. It passes through the influent piping and then through the sand beds. It is then passed through the collection laterals at the bottom of the tanks and passed out of the effluent piping and returned to the pool.

  • Page 10: Multiple Tank - Normal Filtration

    1.3.6 Multiple Tank - Normal Filtration During normal filtration in a multiple tank system, water is split between the multiple tanks. It passes through the influent piping and then through the sand beds. It is then passed through the collection laterals at the bottom of the tanks and passed out of the effluent piping and returned to the pool.

    2 Installation and Assembly If you have purchased the vessel(s) with the optional face piping kit, please refer to additional documentation provided with the face piping kit. 2.1 Receiving and Inspecting • ™ Upon receipt of Stark High Rate Sand Filter(s), check the filter pallet(s) and auxiliary cartons for any evidence of damage due to rough handling in shipment.

RS60 RS72 SS48 46 1/4 SS96 SS96 5S30 5S35 5S40 5S45 5S50 • For “S” vessels, ensure that the tank(s) are level, both across each pipe connection and from the influent pipe to the effluent pipe. For two tank systems, make sure the tanks are level to each other.

  • Page 14: Setting Anchor Bolts

    2.3 Setting Anchor Bolts NOTE: Local, county, and state codes may require that the tanks be anchored in a specific way. Please verify before proceeding with anchor installation. • If the tanks are to be anchored to the slab, mark the holes when the tanks are in their desired position on the slab.
  • Page 15 • Flange Make up – once a flange is joined to pipe, the method of joining two flanges is as follows: • Piping runs joined to the flanges must be installed in a straight-line (flanges must be parallel) to avoid stress at the flange due to misalignment. Once installed, all piping must be fully supported with bracing and hangers (by others) to prevent damage to the system from weight and vibration.

  • Page 51: Operation (Semi-Autonomous Controller)

    2.6 Operation (Semi-Automatic Controller) The diaphragm valve style face piping kits are designed for simple operation and maintenance. Backwashing is accomplished by turning a single knob to actuate the diaphragm valves. The automatic controller can be set up to backwash automatically dependant on certain chosen parameters, as well manually if required (refer to automatic controller manual for more information).
  • Page 52 The semi-automatic controller consists of a single gauge panel with gauges to measure influent and effluent pressures, water pressure supplied to the multiport valve, and the multiport valve knob, which is used to actuate the valves. The influent and effluent pressure gauges show the water pressure coming into and out of the filter system.
  • Page 53 STEP 2: Verify that multiport pressure gauge returns to normal pressure. When actuating the valves the pressure to the multiport valve drops. When the valves become actuated the pressure gauge will begin to rise, and should return to its preset value (35 psi minimum).
  • Page 54 Once system piping and proper valve installation is complete. Including hydraulic lines for valve activation. Hydro test system*. This must be done prior to adding media, start pump, allow system to fill with water to (bleed out all air). Run system for several minutes while doing this inspect for leaks and any unnecessary vibrations that can be reduced by additional support.

  • Page 55: Inspection Of Components

    2.7 Inspection of Components Before performing the initial start up of the filter system, inspect the tanks and components to ensure that no damage has occurred during the shipment of the vessel. • Check for loose, damaged, and missing laterals. If they are loose, tighten them to hand tight, making sure that the slots are facing down.

  • Page 56: Pressure Test System

    2.8 Pressure Test System WARNING : Filters should never be tested or subjected to air or gas under pressure. All gases are compressible, and under pressure create a danger. Severe bodily injury or property damage could occur if the filter is subjected to air or gas pressure.

  • Page 57: Start-Up And Operation

    3 Start-up and Operation The following steps should be followed in the order shown for initial start up of the filter system. Each section will be explained in more detail in the following pages. 1. Start system in backwash mode 2.
  • Page 58 4 Maintenance ™ Although a Stark High Rate Sand Filter vessel is designed to operate for many years with little maintenance, there are some items that should be periodically inspected. In certain situations, periodic maintenance may be necessary. The following is a list of items that should be checked periodically, as well as some maintenance items, which may need to be performed.

  • Page 61 • Install yokes, bolts, and washers. Make sure the yokes are in the proper locations. See picture at right. • Snug yoke bolts. Tighten bolts one full turn past hand tight. If manway leaks during refilling of system, tighten bolts in quarter turn increments until leak stops. After filter is at operating pressure, yokes will be loose due to internal pressure.
  • Page 62 • When the water is drained from the system, drain all of the water in the backwash line. • Loosen any flanges in low-lying sections of piping to completely drain the system of water. • Store any plugs/caps removed near the filter and mark all flanges that have been loosened so that they may be reinstalled and tightened at time of start up.
