4. Switch on. 5. Close outlet. The only regular attention your new pressure system requires is to check the pressure tank’s air charge every 6 months. This can be checked at the air valve with a tyre gauge. Do not charge tank to a higher pressure than 168kPa (XJ Ultra) or 196kPa (XJ70P & XJ90P). Maintenance To check air pressure in tank: 1. Switch off pump. 3. Remove air valve cap from top of Supercell tank and charge tank to 168kPa (XJ Ultra) or 196kPa (XJ70P & XJ90P) using air pump and check with tyre gauge. 6.If no flow is evident from tap, switch off at power point and repeat from step 1 ensuring there is an adequate supply of water available to the pump. Never operate your Davey Dynajet® pump for more than a few seconds without discharge flow. During servicing, use only approved, non-petrochemical based oring and gasket lubrication. If unsure, consult your Davey Dealer for advice. WARNING: Do not use hydrocarbon based or hydrocarbon propelled sprays around the electrical components of this pump. In accordance with AS 3350.2.41 we are obliged to inform you that this pump is not to be used by children or infirm persons and must not be used as a toy by children. 2.

When full, fit Supercell Pressure Tank or Priming Plug as applicable. Davey® Repair or Replacement Guarantee Priming and Operation Prior to using this pump you must ensure that: • The pump is installed in a safe and dry environment • The pump enclosure has adequate drainage in the event of leakage • Any transport plugs are removed • The pipe-work is correctly sealed and supported • The pump is primed correctly • The power supply is correctly connected • All steps have been taken for safe operation Appropriate details for all of these items are contained in the following Installation and Operating Instructions. Read these in their entirety before switching on this pump. If you are uncertain as to any of these Installation and Operating Instructions please contact your Davey dealer or the appropriate Davey office as listed on the back of this document. Power Connection Connect lead to power supply designated on pump label, do not use long extension leads as they cause substantial voltage drop, poor pump performance and may cause motor overload. Pipe Connections For best performance use P.V.C. or polythene pipes at least the same diameter as the pump’s inlet and delivery outlet openings. Larger diameter pipe may be used to minimise resistance to flow when pumping longer distances. Congratulations on your purchase of a high quality, Australian built Davey pressure pump. All components have been designed and manufactured to give trouble free, reliable operation. Before installing your new pump, please read all instructions carefully as failures caused by incorrect installation or operation are not covered by the guarantee. Your Dynajet® XJ pump is designed to handle clean water. It should not be used for any other purpose without specific referral to Davey. The use of the pump to handle flammable, corrosive and other materials of a hazardous nature is specifically excluded. XJ 1. 2. 3. 4. 5. 6. Ultra / XJ70P / XJ90P Pressure tank (supplied separately) Pressure switch Delivery outlet (1”F) Suction inlet (XJ Ultra = 1”F) (XJ70P & XJ90P = 11/4”F) Pump body Motor XJ50 / XJ70 / XJ90 Are the same as above less items 1 & 2. Note: Your XJ Ultra, XJ70P & XJ90P pump is designed to operate as an automatic pressure system when used in conjunction with a pressure tank such as a Davey “Supercell 18C” tank (illustrated). The tank, supplied separately, needs to be fitted to the delivery outlet prior to operating. Assembly Attach pressure switch (2) to the delivery outlet tee (3) by hand tightening the pressure switch union nut (ensure sealing oring is in place). Screw pressure tank (1) onto delivery outlet. Do not use this pump to pump flammable fluids, such as petrol or diesel fuels. Choosing a Site Choose a site with a firm base and as close to the water source as possible with correct power supply. Make sure your pressure system is always connected to an adequate, reliable source of clean water. Do not use pipe thread sealing compounds on any part of this pump. ONLY use Teflon sealing tape. Use unions at pipe connections to enable easy removal and servicing. Use sufficient tape to ensure airtight seal and hand tighten only. To prevent strain on pump threads always support heavy inlet and outlet pipes. If there is a likelihood the water supply may contain solid particles such as pieces of plant or vegetable matter, a suction strainer should be installed before the pump to avoid blocking of the pump. Lay suction pipe at a constant gradient to avoid air pockets which may reduce pump efficiency. NOTE: Suction leaks are the largest cause of poor pump performance and are difficult to detect. Ensure all connections are completely sealed using thread tape only. Installations with a suction lift over 1m require a good quality foot valve to avoid loss of prime. In this case, the poppet valve inside the pump should be removed. Installations with flooded suction require a gate valve so water supply can be turned off for pump removal and servicing. To protect your pressure system from the weather, make sure the pump house is both water proof, frost free and has adequate ventilation. The pump should be horizontally mounted on a firm base allowing for drainage, to avoid damage to flooring etc., that over time may occur from leaking pipe joints or pump seals. Do not mount the pump vertically. WARNING: Some insects, such as small ants, find electrical devices attractive for various reasons. If your pump enclosure is susceptible to insect infestation you should implement a suitable pest control plan. For Automatic Pressure Pumps Installed with a Mains Pressure Hot Water System. A good quality non-return valve must be installed in the pressure pump outlet pipework before the hot water service. Failure to install this non-return valve may result in pump damage. Such damage is not covered by guarantee. Connection of Mains Scheme or Town Water Supply to either Suction or Discharge of Pumps & Pressure Systems Most Water Supply Authorities have strict regulations regarding direct connection of pumps to mains water supplies. In most cases an isolating tank is required between mains supply and pump. Davey also recommend this method. Directly applied mains pressure can exceed pump operating pressure and damage pump. Davey Water Products Pty Ltd can not accept responsibility for loss or damage resulting from incorrect or unauthorised installations. Connection to your Water Source BELOW GROUND WATER SOURCES Whenever the installation position of the pump is higher than 1m (3.3ft) above the lowest water level, a foot valve must be used on the end of the suction pipe as illustrated in (C) below. Ensure that the foot valve is at least 1/2 metre below minimum water level. Where to use Check Valves and Foot Valves Housing your Davey Pressure System IMPORTANT SPEAR POINT INSTALLATIONS When a Dynajet® is installed on a spear or well point, a check valve must be fitted immediately on top of the spear point itself, as shown in (D) above. DO NOT INSTALL THE CHECK VALVE AT THE PUMP OR AT THE TOP OF THE WELL. DO NOT RUN THE PUMP WITHOUT WATER. NOTE:Be certain to select the spear point to suit the well conditions and regulate the flow rate from the pump accordingly. SPEAR SIZE POINT 11/4” (32mm) 11/2” (38mm) 2” (50mm) Abrasive Materials The pumping of abrasive materials will cause damage to the pressure system which will then not be covered by the guarantee. MESH 60 60 60 APPROX. MAX. CAPACITY OF SPEAR 15 - 23 1/min or 200 - 300 gal/hr 23 - 38 1/min or 300 - 500 gal/hr 38 - 75 1/min or 500 - 1000 gal/hr Spear point flow capacities vary considerably. Check with the supplier to ensure the pump and spear point are correctly matched. ">
