DAVEY PHP16 Supercell Pressure Tanks

DAVEY-PHP16-Supercell-Pressure-Tanks - product

WHAKATŪPATO: MAXIMUM WORKING PRESSURE RATING FOR :-

  • SUPERCELL Suffix ‘P’ is 1000kPa (145 psi)
  • SUPERCELL Suffix ‘PHP16’ is 1600kPa (232 psi)
  • SUPERCELL Suffix ‘HP25’ is 2500kPa (363 psi)

WHAKATŪPATO: Wherever it is possible that the pump system pressure may reach or exceed the tank pressure rating under any circumstance (e.g. pressure switch incorrectly set), it is strongly recommended that the system is protected by a suitable pressure relief valve set at or below the maximum tank pressure rating. Failure to install a pressure relief valve may result in tank failure causing property damage or serious personal injury.

TUpato: To prevent personal injury, ensure all water pressure is released from the pressure system prior to work being performed. Ensure pumps are disconnected and/or electrically isolated.

READ ALL INSTRUCTIONS BEFORE INSTALLING YOUR NEW SUPERCELL TANK
These instructions have been prepared to acquaint you with the correct method of installing and operating your Supercell Tank. We urge you to study this publication carefully and follow its recommendations. In the event of installation difficulties or the need for further advice, you should contact the Dealer from whom you purchased the system or your nearest Davey Water Products Sales Office.

FAKATOKANGA:

  • All models (Supercell Suffix ‘P’, ‘PHP16’ and ‘HP25’) will accept water up to 90ºC maximum.
  • Be sure to protect the Supercell tank and all associated pumps and piping from freezing temperatures.

INSTALLATION MUST BE IN ACCORDANCE WITH LOCAL PLUMBING CODES WHERE APPLICABLE.

Tank Tuhinga o mua

For correct operation pressure tanks should be pre-charged as follows:

  •  For pressure switch controlled pumps with cut-in pressure set at 140 kPa (20 psi), pre-charge the tank to 15kPa (2 psi) below the cut in pressure.
  • For tanks installed with a pressure switch controlled pump with a differential pressure set up to 200 kPa (30 psi), the pre-charge should be set to 15 kPa (2 psi) below the cut-in pressure.
  • For tanks installed with a pump controlled by a pressure switch with a pressure differential greater than 200 kPa (30 psi), electronic controls or variable speed controls, the pre-charge should be set to 65% of the cut-out or maximum system pressure.
  • For tanks installed on mains’ pressure, the tank pre-charge should be set equal to the mains’ pressure. For mains’ pressure exceeding 6 bar (88 psi), a suitable pressure regulator should be installed.
  • For hot water expansion, pre-charge should be set as per the mains pressure details above.

For your convenience, all suffix ‘P’ pressure tanks have been factory set at 200kPa (29 psi) and suffix ‘PHP16’ and ‘HP25’ models which have 400kPa (58psi).

CAUTION: Never over-charge the tank and use air at ambient temperature only!

Tāutatanga

NOTE: To avoid possible water damage to property from ruptured pipes, leaking connections, worn/leaking pump seals, etc., pumps and associated equipment (including this Supercell Pressure Tank) must be installed on a well drained site or in a properly constructed water proof enclosure with drain tray.

Bottom Entry Models
Connect the tank vertically in the outlet piping of the water pump being used. Thread seal tape is necessary.
Kaua e whakakaha rawa!

Base Mounted Models
These units have the inlet positioned on the bottom of the tank. Ensure that any fittings used firmly retain the pipe or hose connected. Thread tape should be used on all threads.
The tank should be placed on a firm base. If vibration is likely to occur in the vicinity the tank should be mounted on a resilient mount.
In order to ensure your tank provides its maximum service life it should always be installed in a covered, dry position. The tank should not be allowed to rub against any surrounding hard surfaces, such as walls, etc.

  • Installation Inside Buildings: To cater for possible plumbing or tank failure, the installation must include an enclosure that will capture any water spraying from the tank and direct it into a properly constructed drain tray.
  • Note: When installing a Supercell Tank and/or associated pump system inside a building, allowance for possible high pressure leakage MUST be made.
  • Note: In order to carry out routine maintenance the Supercell Pressure Tank MUST be easily accessible to the end user or home owner.

Te Tirohanga me te Whakaki i te Utu Rererangi Tank

Supercell ‘P’, ‘PHP16’ and ‘HP25’ Pressure Tanks do not require regular checks under normal operating conditions. However, if air charge adjustment is required then follow the following procedures:

  1. Remove the pressure tank completely from pump installation, ensuring to isolate the pressure tank and release the water pressure from the tank beforehand. OR
    Release all water pressure from the pressure tank by switching off the pump at the power point, and opening the closet tap. For above ground supply tanks it is necessary to close the gate valve between the supply tank and the pump.
    CAUTION: To prevent personal injury, ensure all water pressure is released from the pressure system prior to work being performed.
    Waiho te tap kia tuwhera i te wa e whakakii ana te hau.
  2. When all water pressure has been released from the system, check air pressure at air valve on top of pressure tank. The pre-charge pressure reading should be as detailed on page 3 of this document.
  3. If necessary, replenish air charge to the correct pressure indicated. Ensure that a tap in outlet piping of pump is open during replenishment of air pre-charge.

Nga Tirohanga o ia wa
Flushing: Depending on the quality of the pumped water, from time to time your tank may require flushing to remove settled fines such as mud or sand. If sand or mud is allowed to stay in the tank it will accelerate wear on the internal lining and shorten your tanks life. Safely disconnect the tank from the water supply, discharge all air from the tank and flush the tank several times with clean water. Once the flushing water is clean, reconnect the tank and recharge the air as per above.
External Inspection: A tank in good order will not leak, but over time due to damage through rough handling, impacts or grit and/or impurities in the water the tank shell may fail and/or leak. Should the tank leak or show signs of possible failure the tank should be immediately disconnected and replaced.

WHAKATŪPATO: Do not use tank if it leaks or shows signs of corrosion or damage.

Operational Difficulties & Trouble Shooting

NOTE: Loss of air charge is the most overwhelming cause of difficulties with Supercell Pressure Tanks. Partial or complete loss of air charge will cause any of the following problems:-

  • Rapid pump cycling (i.e. pump stops and starts frequently during operation).
  •  Decreased draw-off capacity.

Alternatively, the same problems could be caused by a punctured or leaking diaphragm as indicated by water leaking from the air valve when the valve core is depressed (typically when checking tank pre-charge).
Supercell Suffix ‘P’, ‘PHP16’ and ‘HP25’ models have a diaphragm which is captive and is non-serviceable. In the event of diaphragm failure the whole tank must be replaced.

Tohutohu Nga take Nga rongoa
Pump Cycling

(Pump stops and starts frequently while operating)
  1.  Punctured diaphragm (check that water escapes from air valve when depressed)
  2.   Incorrectly set pressure switch
  3. Incorrect pressure tank pre-charge
  1.     Whakakapia Tank.
  2.   Reset pressure switch to manufacturers recommendations
  3. Adjust tank pre-charge to 15kPa (2psi) below cut-in
Pump stops and starts when all taps are closed
  1.  Leaking tap or pipework on suction and/or discharge side
  1.   Isolate suction pipework, if pump continues to stop and start, check for leaks on discharge. If pump stops and does not restart, problem is likely to be leaking check valve on suction side of pump system.
Water flow from open tap stops then starts when first opened
  1.    Tank pre-charge set too high or too low
  2.   Pressure switch cut-in set too low
  1. Adjust tank pre-charge to 15kPa (2psi) below cut-in
  2.  Adjust pressure switch cut-in
Tank will not hold air pre-charge
  1. Faulty air valve
  2. Diaphragm kua werohia
  1. Replace air valve core

Note: Where a pressure switch differential range exceeds the above, the Acceptance Factor must be calculated and must be less than 0.5. If the AF value exceeds 0.5 then the differential must be reduced by either increasing the cut-in and pre-charge pressures or by reducing the cut-out pressure.
AF = (cut-out kPa – pre-charge kPa)
(cut-out kPa + 100)
