Introduction Congratulations on your purchase of a high quality, award winning Aquashield MAX Ultra Violet water treatment system. Aquashield MAX represents advances in safety and convenience of rainwater harvesting technology for commercial and large scale rainwater users. The range offers increased water treatment quality and safety - producing water that is biologically safe to drink, without the use of chemicals.
Preparing Your System Your new Aquashield MAX system incorporates a lamp failure system design feature that enables you to be warned of a lamp failure by :1. A lamp failure LED 2. An audible alarm 3. Remote alarm contacts 4. Pump lock out feature In addition when the alarm “beeps” on and off, the lamp is due to be changed so effective treatment is maintained.
Prior to using this system you must ensure that: • • • • • • • The system is installed in a safe and dry environment The system 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 Choosing a Site Choose a site with a firm mounting position. Allow room for removal of the lamp and sleeve during servicing.
Pipe Connections NOTE: Prior to installation remove the transport plugs from the inlet, outlet and lamp end cap. 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. 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.
PUMP Controllers Torrium ® Your new system incorporates ‘Torrium®’, electronic flow controller – a Davey designed unit that enables the use of a highly efficient pump design and offers the following benefits:– 1. Enables the pump to deliver a constant flow of water particularly at low flow rates – reducing the inconvenience of pressure variation in showers etc. 2.
Only one fault condition will be indicated at once. Both the Red & Green Indicators are shown in the same window. It is possible for the pump to be running (ie. Green indicator) and for a Red flash sequence to happen at the same time. In that case the Red flash will show as a Yellow or Amber flash. Cistern Fill Mode When your new HP or HS pressure system is used to fill toilet cisterns or troughs, a special feature of the Torrium® controller may be activated.
Auto-retry and Water Return Modes Should your Torrium® detect a loss of prime, after stopping the pump, it will wait five minutes before activating Auto-retry and Water Return modes. Auto-retry automatically starts the pump to see if the pump is now primed. It does this after 5 mins, 30 mins, 1 hr, 2 hrs, 8 hrs, 16 hrs and 32 hrs. Water return mode will restart the pump automatically if the Torrium® detects water flow through it.
RainBank® – How it works 1. When there is demand for water from your toilet, washing machine or garden tap RainBank® senses this demand and checks the level of water in the rainwater tank. Note: demand must be greater than 1.5 litres per minute or mains water will be delivered. 2. If there is rainwater in the tank RainBank® switches on the pump.
Work out the correct position for the hole for the float switch. With a corrugated profile tank wall this is on the upper flat section of the profile as shown below. Note: Ensure level sensor is installed with ‘UP’ facing up Centre hole on flat section of profile Diameter of hole must be 22mm. 0 15 Work out the correct location of the float switch relative to the pump outlet. 40 To Pump 0 10 Slab The float switch location should also be: • At least 40mm above the pump inlet.
IMPORTANT: To allow easy connection it is strongly recommended that you have flexible copper pipes that allow some movement so that they can line up exactly with the mains water and rainwater outlet. These pipes must be 3 ⁄4 inch in diameter. IMPORTANT: It is highly recommended that an isolation valve be fitted to where the mains water enters RainBank® and between the pump and the rainwater tank.
Pre-treatment (filtration) Prefiltration is usually required to ensure that particulate matter does not shield micro-organisms from the UV light. Sand filtration or 20 micron cartridge filtration is the usual minimum, this is provided in Stage 1 filtration. In some cases, particularly with surface water, finer filtration may be necessary, or if cysts like Giardia or Cryptosporidium may be present. In this case 1 micron filtration is required, as provided in Stage 2 filtration.
oring into the groove and with two fingers wipe the oring down into the groove. Do not wipe the oring clean of lubricant after it has been properly seated in the groove because the lubricant prevents “crawling” of the oring during the tightening of the lid and thus prevents water leaks. 5. Screw the housing onto the lid and hand tighten. Open the tap downstream of the filter and then open the inlet valve.
The appliance is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure they do not play with the appliance NOTE: The quartz sleeve has been factory fitted, and there is no need to remove these endcaps on first installation. Before removing endcaps, please read the Maintenance section of these instructions completely.
Lamp Installation Once the Steriflo® Treatment Chamber has been connected to the pipework, the installation should be checked for water leaks. Attach the “DO NOT LOOK AT LAMP” sticker in an obvious position on the treatment chamber, check that the chamber is clean to ensure the sticker will adhere correctly. The Quartz Sleeve is pre-installed in the treatment chamber, and provided the endcaps have not been disturbed or undone, is able to withstand well in excess of the maximum operating pressures.
Maintenance Lamp changing (every year of operation) : 1. Shut valve(s) so that water cannot flow through steriliser. 2. Switch off steriliser by unplugging mains. 3. Undo end cover screws. 4. Unplug lamp connector. 5. Remove lamp. Reverse procedure when replacing lamp, ensuring that lamp is centrally located in the chamber. Handle only by the ends. Quartz Sleeve Cleaning : If dirt is allowed to build up on the quartz sleeve it will impair the UV output.
Maintenance continued... Reverse procedure when replacing sleeve. When replacing quartz sleeve after cleaning, the sleeve should stick out about 1cm at each end. Place o-ring over closed nut end and fit closed nut, fastening it hand tight. Hold the other end of the sleeve in position during the tightening with the other hand, then fit open end o-ring and cap. A tiny amount of silicon spray or CRC in the end of aluminium endcap threads will aid easy tightening.
TROUBLESHOOTING Torrium ® a) PUMP HAS STOPPED OR MOTOR RUNS FOR SHORT PERIOD ONLY WHEN SWITCHED ON OR PRIME BUTTON PUSHED, BUT DOES NOT PUMP - STATUS INDICATOR LIGHT ILLUMINATED RED FLASHING ONCE PER SEQUENCE 1. Suction line and pump body not filled with water. 2. Air leaks in suction lines or suction pipe not under water. 3. Air trapped in suction lines (also possible with flooded suction due to uneven rise in piping; eliminate humps and hollows). 4. No water at source or water level too low. 5.
f) PUMP WILL OPERATE NORMALLY INITIALLY BUT WILL NOT RESTART ON WATER DEMAND - STATUS INDICATOR LIGHT NOT ILLUMINATED 1. Power supply problem - see c) 1. g) PUMP WILL OPERATE NORMALLY INITIALLY BUT WILL NOT RESTART ON WATER DEMAND - STATUS INDICATOR LIGHT IS ILLUMINATED RED CONSTANT 1. Suction air leak - pump has partially lost prime. 2. Blocked impellers or suction. 3. Discharge valve closed - open valve. RainBank® a) PUMP WILL NOT SWITCH OFF 1. Pump plugged directly into power outlet.
pump starts plug the pump back into the RainBank® and continue fault finding. If the pump does not start contact your supplier for further advice. 9. Lead from float switch to pump broken or damaged. Replace float and lead assembly. 10.Float switch defective. Contact your supplier for further advice. c) OTHER SYMPTOMS Mains water is still in use when pump is running. Possible cause - pump needs to be primed.
STERIFLO® Principle. A ballast (choke) provides the correct voltage and current for the lamp(s). The circuit board monitors the current to the lamp and if it is not present, illuminates the red alarm light and sounds the alarm buzzer (a “squealing” noise). An orange light indicates the power is on. a) UV LAMP OUT, NO ORANGE “ON” LIGHT, NO ALARM 1. No mains voltage. 2. Internal fuse failed. 3. Check mains power connections inside power supply. b) UV LAMP FLICKERING, ALARM ON 1. Failed lamp. 2.
WARNING ULTRA-VIOLET RADIATION IS HARMFUL TO SKIN AND EYES. EYES Switch off UV system before removing covers. If working within line of sight of UV light, ensure that a suitable full face plastic facemask is worn. SKIN It is recommended that exposed skin is covered to prevent sunburn, possibly severe, if working within line of sight of operating UV system.
