1. gt ouupric ACCUM INSTALLATION MANUAL The SHURflo Accumulator tank is a bladder type pressure storage vessel and or pulsation dampening device designed to hold water under pressure The accumulator tank provides additional water storage to assist the pump in meeting the total demands of the system It extends pressure switch controlled pump life by reducing pump on off pulsation NOTE This product is not recommended for use with a 4900 or 5900 Series Smart Sensor Pump e See Product label and Specifications section on page 2 for factory pre charge pressure Do not exceed 40 psi 2 7 bar pressure for long term storage shipping or during system non use e It is recommended the pre charge be checked seasonally or any time the accumulator does not appear to be functioning properly Temperature extremes and changes in altitude can affect accumulator pressure and performance Use a standard tire pressure gauge to check the pressure The valve stem cap MUST be tight to prevent air leakage e The accumulator may be placed anywhere in the pressurized side of the plumbing It should be installed after the pump and before any filters or check valves that can add backpressure to the pump or system The ports are non directional in flow and do not have to be plumbed in line one side can be capped e The accumulator can be mounted in any position However for complete sanitizing winterizing the recommended mounting position is with pre charge valve stem2. ation information es wa V Typical Accumulator Installations LLL Accumulator installed next to pump Accumulator installed with tee fitting In line installation Screw included fittings on tank and cut flex line on outlet side of pump Use hose clamps to tighten hose to fittings Tee installation Water does not need to go through accumulator Cap one end of tank and install as shown Tank still adds pressurized volume to system Accumulator installed in line G m Bia Tank Pump Accumulator Hot Water Tank Fixture Dual swivel included in retail pack 182 Accumulator 911 731 C 08 06 ECN 12681 Page 1 of 2
3. up Do not freeze or mount near a high heat source e Threaded fittings plastic nylon only should be torqued approximately 1 2 to 1 turn after hand tightened Never exceed 6 ft ibs 88 Nm of torque on the ports Plumb the system using high pressure 2x pump rating braided flexible tubing to minimize vibration noise RV MARINE APPLICATIONS WITH PRESSURE SWITCH CONTROLLED PUMPS The accumulator contributes to longer pump life less noise less amperage draw and reduced water pulsation The most efficient use of the accumulator occurs with the pre charge set at the SAME pressure as the pump s pressure switch turn on setting Typically a 45 psi 3 bar pump will turn on around 30 psi 2 07 bar Therefore the pre charge should also be 30 psi 2 07 bar The pre charge MUST be set in a static condition pump off and at least one water fixture opened Depending on pre charge pressure to the accumulator in relation to the pump turn on off pressures stored liquid is about 2 to 4 oz 60 120 ml If accumulator tank pre charge exceeds pump turn on pressure the liquid volume is reduced PLICATIONS oea gq devic water hammer or noise suppressor th pre charge should be set at the operating a gauge in the offending plumbing where the accumulator can be mounted Adjust the valve so read the pressure Set the pre charge to the Observed pressure remove the gauge and install URflo Service Bulletin 1024 for more applic
