| EXTERNAL PUMP POND VACUM INSTRUCTIONS |
| ||||||
| A QUICK EXPLANATION One of the main reasons for the high price of commercial pond vacums is the need to achieve an airtight seal on the vacum container in order to enable sucking the water from the pond edge up to the cannister and through. Manufacturers solve this with expensive seals and heavy duty plastic castings. To solve the airtight problem I simply put the cannister in the pond now the only connection that has to be airtight is the one right at the pump. If for some reason you do not achieve adequate suction you can tape the seam around the lid with plastic duct tape, check bulkhead nuts are tight, wrap teflon tape around pipe connections before slipping on hose and tightening clamps. (the hose can also be glued to fittings) ASSEMBLY INSTRUCTIONS FOR PUMP OPERATED POND VACUM LID Look inside the rim of the lid and you will see a ridge running along the outside flap, this ridge holds the lid on to the bucket. Note where the ridge ends and make small cuts in the lid according to diagram ( pv 1 ). These allow the lid to be removed much more easily. Be carefull to cut only the outer rim of the lid and only to the lip. Drill hole in center of lid to receive bulkhead fitting (pv 2 ) for pump connection. Double check to be sure of hole size by drilling a practice hole in a piece of scrap and checking fit of bulkhead fitting before drilling lid. BUCKET Drill hole in side of bucket to receive bulkhead fitting (pv 3) for vacum hose attachment. Drill about 2 1/2" up the side from bottom of bucket to allow for flange on bulkhead fitting Double check to be sure of hole size by drilling a practice hole in a piece of scrap and checking fit of bulkhead fitting before drilling bucket. Make sure you have the appropriate fitting or adapters for the hose you will be using as a vacum. SCREENS easier to make but not as easy to use as filter blocks To make 1/2" screens (pv 4 ) cut a square of 1/2" hardware mesh just large enough to wedge into the bucket at the appropriate height remembering the debris comes in from the bottom so put the larger mesh in the lower part of the bucket. The 1/4"screens(pv 5) are made the same way as the 1/2" and are positioned higher in the bucket. You may place a layer or two of filter material(pv 6) between the top screens to get the finer materials. Although it is not absolutely needed as long as you screen out the larger debris to prevent plugging the pump and dont return the water to the pond. FILTER BLOCKS Cut a second bucket into two inch wide bands, pick a band (pv 7) that will sit inside the vacum bucket just above the inlet bulkhead fitting. Using either 1/2"hardware screen or 1/2"plastic light diffuser panel cut a piece to fit inside the top and bottom(pv 8) of this band. Using a suitable glue (I use great stuff foam with excelent results) fasten the screens about 1/4" - 1/2" down inside the band(pv 9). As with the above screens you have the option of sandwiching some filter fabric between the screens in your top block. Assemble all parts as depicted on drawing . Dont worry about sealing the connections other than the connection to the pump (pv 11 ) as they will be underwater and a slight leakage is okay. VACUM HEAD AND HOSE Build the vacum head as described in the syphon vacum plans but substitute a 1" line in place of the 1 1/4" line I find a plastic (950 ml. or 1 quart) gatorade bottle fits the 1" hose quite well. OPERATING INSTRUCTIONS DANGER BEFORE OPERATING POWERED POND VACUM BE SURE YOU ARE PLUGGING IN TO A G.F.I.C. PROTECTED ELECTRICAL CIRCUIT EXTREME ELECTRICAL SHOCK HAZARD USE ONLY A SUBMERSIBLE PUMP After completing assembly of all parts and attaching the vacum hose. Take the whole unit to the pond side. I strongly suggest having a helping hand for the first few times until you get the hang of operating this unit. Decide what to do with the removed water and make those arrangments ( I.E. attach a garden hose to pump and run it to the rose bed or whatever) Tie a line to the handle of the bucket and tie this to a stake or peg to keep the bucket in place and hanging below the surface. I have a broken golf shaft about 3' long it has a nice rubber handle and a narrow end that is easy to stick in the ground. set the bucket in the pond and leave the pump outside of pond. Insert garden hose from house in vacumhead and begin filling with water, as the bucket fills it should sink and eventualy water will start coming out of the pump. When this happens put the vacum head underwater with the hose still running in it then turn on the pump and keep the hose running until all the air has left the line and the vacum is running smoothly. Have helper turn off the hose and remove it from vac head . Proceed to vacum pond keeping the vacum head under water at all times or you will have to start it again. If you need to stop for any reason place the pump in pond then turn it off. This stops the pump from losing its prime. If you are vacuming and it sudenly stops sucking usualy it has lost its prime due to an air bubble from lifting the vac head. Check for blockages then insert the garden hose in vac head and try starting the procedure again. The vac bucket can get full or plugged occasionaly so keep that in mind. Also if you find it is plugging to often you may have to change the type size or amount of screens or filtering medium in the bucket. |
