Bottom 11/4” 81.3 For correct operation pressure tanks should be pre-charged as follows: • Pressure switch controlled pumps with differential pressure set at 140 kPa (20 psi), pre-charge the tank to 15kPa (2 psi) below the cut in pressure. • For pumps controlled by pressure switches with higher differential pressures, electronic controls or variable speed controls, pre-charge the tank to 65% of the maximum system pressure. • Pressure tanks installed on main pressure, pre-charge should be set at the mains pressure. • For hot water expansion, pre-charge should be set at the mains pressure. For your convenience, this pressure tank has been factory set at 140 kPa (20 psi). 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. 71.8 95.0 67.1 860 Supercell 250F 250 88.1 99.7 103.1 546 1303 Bottom 11/4” 65.0 57.4 76.0 53.7 860 Supercell 200F 200 70.5 79.8 82.5 546 1098 Bottom 1” 37.3 49.4 34.9 860 Supercell 130F 170 45.8 51.8 53.6 42.3 421 1211 Bottom 1” 28.3 37.3 26.3 860 Supercell 100F 100 34.5 39.3 41.3 44.3 421 980 Bottom 1” 23.0 30.4 21.5 860 Supercell 80F 80 28.2 31.9 28.7 35.5 421 865 Bottom 1” 17.2 22.8 16.1 860 Supercell 60F Tank Model 60 21.2 23.9 24.8 26.6 421 649 Position Inlet Size (BSP male) Height (mm) 250-400 (36-58) 200-400 (29-58) 150-250 (22-36) Tank Capacity (litres) 150-300 (22-44) 250-500 (36-73) 300-600 (44-88) 500-800 (73-116) Diameter (mm) Dimensions Pressure Switch Range kPa (psi) Nominal Draw Off Capacity in Litres Max Pressure Rating (kPa) -6- Tank Pre-Charge 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. -3-
