when installing inside a building. Ensure easy accessibility for
routine maintenance.
Checking and Replenishing Tank Air Charge:
Under normal operating conditions, Supercell Pressure Tanks do
not require regular checks. If air charge adjustment is needed,
follow these steps:
- Remove the pressure tank from the pump installation and release
water pressure. - If above ground supply tanks, close the gate valve between the
supply tank and the pump.
FAQ:
Q: Do I need to regularly check the air charge of the
tank?
A: Under normal conditions, regular checks are not required.
However, adjustments may be needed occasionally.

Installation and Operating Instructions
SUPERCELL Suffix `P’, `PHP16′ and `HP25′
PRESSURE TANKS
WARNING: 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)
WARNING: 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. CAUTION: 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.
Please pass these instructions on to the operator of this equipment.
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.
NOTE: * 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 Pre-Charge
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!

Installation
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.
Do not overtighten!
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.
I
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.

Checking and Replenishing Tank Air Charge
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.
Leave tap open during air replenishment.
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.
NOTE: During air replenishment the tank should be externally inspected. Any signs of leakage from the tank may indicate a need for immediate replacement.
Periodic Checks
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.
WARNING: 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:-
a) Rapid pump cycling (i.e. pump stops and starts frequently during operation).
b) 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.
