A division of Pentair Flow Control Paci c Pty Ltd 83 000 922 690 These instructions act as a guide only and do not cover every aspect. Owners notfamiliar with pumping equipment should seek advice from their pump dealer orSouthern Cross CBI Series Pressure Systems are designed for pumping non-aggressivewater, and water not containing solid particles.

2 Never install the pump in areas wherethe ambient temperature exceeds 40 C. The temperature of the pumped liquid shouldbe within the range of +4 C to +60 C. Before installing the pump ensure the rotatingparts turn pump should be installed as close as possible to the liquid source, and coveredby a weather-proof housing, well ventilated to allow motor heat to escape. The pumpfoundation should be rigid enough to absorb any vibration from the motor, and the pumpshould be securely bolted to the foundation.

3 It is also recommended that the plumber/installer provides an adequate draining system to avoid damage in case of leakage,particularly when installed suction line should be as short and straight as possible, with aminimum of bends. The internal diameter of the suction pipe mustbe equal to, or greater than the ports of the pump. Theconnection between the suction line and pump must beairtight, and the suction pipe must be positioned so it hasan upward slope to the pump (thus avoiding the formationof air pockets) and must be fitted with a reliable checkvalve(supplied with unit) for correct operation.

4 Whenused on a suction lift a footvalve should be fittedon the suction line, below the liquid level. For longsuction pipes or high suction lifts over four metres,the suction pipe should be of greater diameterthan the suction port. On all installations wherewater is drawn from wells, dams and creeks, anadditional strainer must be fitted to the inlet tothe suction line, to ensure any solids in the waterdo not enter the pump. If hose is used as thesuction line, it must be minimise pressure drop the discharge pipe should be at least the same size as thedischarge port of the pump.

5 All piping should be independently supported and in noway apply any strain to the pump casing with all pipe joints securely tightened andsealed using a jointing : All wiring should be carried out by a fully qualified the mains voltage is the same as the value shown on the motor plate and thatthe pump is safely connected to ground/earth. All single phase (240 V) motors aresupplied with a 3 pin plug and lead and can be connected directly to the mains single phase pumps/motors are fitted with a thermal overload protection which willautomatically reset when the temperature returns to normal.

7 Automatically perform all its normal functions, however if there is an operational breakdown (ie. lack of water, blockage in suctionpipe, etc) the unit will recognise the breakdown, send a stop signal to the pump andsubsequently light the red Failure LED. Once the problem has been rectified, theunit can be restarted by pressing the Reset fault FindingFaultPossible CausePump won t prime/- Footvalve may be liquid delivered- Suction lift too Air leak or blockage in suction Footvalve not installed below lowest water Footvalve/checkvalve installed in the wrong Voltage or wiring of motor Strainer Pump speed too Pump impeller runs at - Suction lift too capacity- Suction or discharge line Pump impeller partly blocked by Footvalve/checkvalve or strainer partly

9 - Suction lift too starting, the pump must be primed. This is done by removing the priming plugand completely filling the pump with clean water. On pumps with suction lift the suctionline should also be filled. Ensure the priming plug is tightened in place once pump hasbeen Installations where the pump inlet is belowthe water supply remove the priming plug andallow the water to flow into the priming chamberuntil all air is expelled. The priming procedureshould be repeated until all air is expelled andthe pump delivers a full stream of water withoutair bubbles.

10 The pump must always be checkedfor prime if not used for a prolonged period. Itis imperative to fill the pump with liquid beforeoperation as dry running causes irreparabledamage to the mechanical pump should be shut down and the troublecorrected if the pump is running at speed andfound to have any of the following problems:- No liquid delivered- Not enough liquid delivered- Excessive vibration- Motor runs hotDo not allow the pump unit to continually start and stop (short-cycle) as this will reducethe motor life.
