B is an adjustable sleeve which attaches to the base of the unit and then on to exit pipe work C is the locking fastener This is used to bleed the unit and also to remove the screen for cleaning D is a spigot which allows the Answer to be mounted E is the pump itself backwash pump made and designed especially for the Answer units Answer 410 325 INT UK Manual Rev 1 05 F is the return line from the pump G is the hollow rotor arm which is almost the same length as the BO inside diameter of the unit It is connected to the pump outlet and the water leaves via the two jets at each end of the rotor arm Once the unit is started the rotor arm begins to rotate and the powerful exit jets force water from the inside of the chamber against the inside of the stainless steel screen This constant action prevents any solids from sticking to the screen on the outside of the unit Instead the solids are dislodged from the screen and settle out at the bottom of the chamber which houses the unit H is q locking screw which is used as a security lock so that you can not dismantle the pump when it is running ON OPENING find the following 1 Stainless steel filter 2 Rubber sleeve 3 Backwash pump AN pa 2 Is already connected to the filter 3 needs to be connected and locked with the locking screw H that is already screwed into the pump2. Be prepared for very large amounts of debris to be collected for discharge especially in the first week or two of running The unit will not allow most pond particles to pass Mature systems which appear to be clear before installing this unit are in fact not so mechanically clear as previously believed as the unit will prove RETURN TO POND In view of this do be prepared to make discharges of the prime Unit to waste regularly as the unit is continually clearing all previous debris out of the system Once The Answer has done it s job in clearing the pond of the solids build up from the existing water it will then be able to operate with normal day to day feeding etc Discharges will not be needed so often once the system is under control page 8 A minimum of 250mm is needed below The Answer to allow good settlement otherwise debris will be held in suspension due to the action of the rotor arm if the unit is too close to the bottom of the orime settlement tank MAINTENANCE SECTION Maintenance of The Answer Cleaning of the container which houses the unit depends on the volume of the container in question together with the amount of waste collected this varies dramatically from pond to pond How often you choose to discharge the container itself should be determined by your own experience of your own system Occasionally in cases of high stocking densit

7. such ideas To date none have been even mildly successful The Answer has been designed and developed specifically to Answer 410 325 INT UK Manual Rev 1 05 address this age old problem Like all ingenious ideas The Answer is simplicity itself There are now 2 different models all function the same designed the same but cater for different sized ponds and flow rates The Answer 410 Filter Unit 150 200 micron screen Maximum flow rate 13 000 litres 2 863 gallons per hour Voltage 240 Volts 50 Hz Wattage 270 Watts Diameter 410 mm Depth 400 mm The Answer 325 Filter Unit 150 200 micron screen Maximum flow rate 10 000 litres 2 202 gallons per hour Voltage 240 Volts 50 Hz Wattage 200 Watts Diameter 325 mm Depth 370 mm Actual screen size is 150 micron unless otherwise stated on the Answer box The Answer without its screen page 2 _ a 4 _ ae uu eat leg E aE sheh l ae ua HE EEEE i i i qth ti Hise Hit LX C The Answer Components OPERATION There are several ways The Answer can be installed into the mechanical stages of filtration but it is first best to explain the operation in detail A is a reinforced stainless steel screen which only allows particles of less than the screen size to enter the inside of the unit
8. ING CHAMBER BIGLOGICAL STAGE page 7 Call your dealer for any queries on inlet pipe work conversions c For box type filters either pump or gravity fed This installation is self explanatory as the diagram illustrates again a slide valve is recommended here Fitting the unit to the induction side of the main circulating pump Is less preferable than what we have described If the unit is fitted to a system directly before a pump extra special care must be taken with the cleaning maintenance discussed later This is because a slight blockage of the screen will allow the pump to literally suck in the screen causing the rotor arm to stop spinning Pumping direct from the Answer Important If installing on the induction side of a pump please contact us for an air vent which is essential to use in this application This application will assist in removing all heavy solids before they enter a bead filter In truth there are few applications that will not allow the fitting of The Answer to any pond system However if you are in any doubt as to the best fitting methods for best results in your system please contact us for our advice Another point should be mentioned here to those fitting Answer 410 325 INT UK Manual Rev 1 05 The Answer on a pond for the first time

10. d in the next stages Also it prevents dirty water from entering The Answer from the bio stage when emptying and cleaning the prime tank vortex It Is also vital to have a slide valve prior to the bottom drain line entering the vortex Important It has been discovered during trials of prototypes that the tube entering the prime vortex unit MUST be extended upwards by fitting a 90 degree elbow and a short piece of pipe as shown on previous page This allows the water to enter the page 6 container level with the centre of the screen upright position thus creating extremely efficient settling out of all debris As such the spinning inside the vortex is stopped rendering it q catchment tank If the spinning were allowed to continue fine debris would not be allowed to settle and would remain in suspension potentially causing an overload to the screen and subsequent decrease in performance over an extended period of time This modification should also be done in any prime container whether it is q round square or rectangular tank In this installation the vertical exit pipe from the vortex may have to be reduced in height to ensure the Unit sits completely below water level in normal running We suggest a Z et ea ee ee 2 WATER LEVEL SLIDE VALVE SLIDE VALVE TO WASTE lt the unit is located as near to mid height in the vortex as possible This although n
