Manual of RDF-Rotatory Drum Filter Congratulations with your new drum filter! Please read this manual before installation and use. Thank you for purchasing our Rotating Drum Filter, the first rotating drum filter that s powered by water pressure. The RDF drum filter is not only a whole new design but also a total new concept in drum filtration. The RDF drum filter has a list of advantages you will not find in any other drum filter. Some of these fine features are the total noiseless operation. No electricity is needed for operation. So safe and secure. The most high capacity of the RDF in the most small stainless steel housing, thanks to the waste basket who can operate totally under water. This creates a high water level difference between pond and filter. Also the blanket weed cannot stuck inside, because the drum is totally smooth and all weed is collected on the easy place to remove. The cleaning device of the drum itself is unique and cleaning the drum is not needed anymore forever. So no dangerous acids or whatsoever. Going down to 10 microns is a very fine feature and can even replace a standard sand filter for swimming pools. This filter is made of high quality 316L stainless steel. This filter has broad applications: from koi ponds, salt water aquarium, swimming pools, aquaculture and aquaponics. From its low water consumption and energy savings this filter provides an environment friendly solution to water filtration. We wish you a very successful use of the original RDF. If you still have questions after reading this manual do not hesitate to ask your dealer. He will be happy to help you out. Bert Schuldink President Estrad BV

Content and unpacking After taking off the lid of the wooden crate by removing the screws please take care to have read this manual. Remove the side walls of the crate as this will allow full access to the Drum filter. (The crate is made high grade plywood that you may choose to save for future use in other applications that you may desire.) After the box walls are taken down, remove the tape from the lid all around and open the RDF drum. Remove all of the packing materials from the filter and the float tube. The float tube should then be inserted onto the float tube pin very carefully. The raising and lowering of the float tube triggers the wash cycle. Check to see that the float tube can move up and down the pin in a smoothly fashion. Floating Unit Also check to see that the drum can rotate by pushing it forwards by hand. Take care that you only move the drum in the direction of the arrow located on the filter beside the drum. When rotating the drum by hand a clicking sound will be emitted. This direction ONLY.
Installation Install the filter on a flat area of concrete or other solid surface. Locating the filter closer to the water source is preferred simply because better water flow is achieved by virtue of there being less resistance from the use of less piping. The unit should be installed so that it is horizontal. A level should be used to ensure that the unit and is fully horizontal. If the mounting surface is not level, leveling of the filter can be accomplished by adjusting the feet beneath the filter as they are may be raised and lowered by rotating them. adjust here by spaner The filter should be installed so that the top of the DRUM within the filter is level with standing water line within the pond, pool, tank or other body of water that s being filtered. In other words, the standing water level inside the filter should be between the top of the filter drum and the horizontal plate that holds the float tube. (When your water pump is a turned on and filtration begins there will be a drawing down of the water inside the filter so that the top of the drum will no longer be fully submerged beneath the water.) Top of the Drum Floating Unit Holder The lid The lid can be opened from left or right side by interchanging the hinges.
The lid can be opened from either side to suit your installation requirements. Reversing the lid s configuration can be accomplished by taking the lid off the hinges and remounting them on the pre-drilled openings on the opposite side for the filter. It is important to operate the filter with the lid. The lid has been designed to strengthen the filter and to minimize any noise emanating from the spray nozzles during a wash cycle. A chain connects the lid to the filter to keep the lid within easy reach when the lid is open. In windy areas you have to secure it cannot fall down during maintenance. There is a locking mechanism at the side of the lid. Simply pull the black ball away from the lid when open and closing the lid. The lid locking mechanism is a child safety feature. Safe pin Piping After the drum has been set to the correct height and leveled by the adjusters below, it s time for connecting the water pipes. Begin with the 4 inch water pipe inlets. It s preferable to make the connections as short as
possible and use sweeps as opposed to 90 degree elbows. If a short run is not possible, please consider using a wider diameter pipe and reduce the diameter shortly before the RDF. There are 4 water inlets and using more of them will increase water flow through the filter. Connecting pipes to the RDF may be accomplished with Fernco fittings. Any water inlet not being used should be capped with rubber Fernco fitting. The total capacity of the RDF depends on these water inlets. There are two water outlets. It is preferable to utilize the water outlet that is on the same side as the UV light as this will create better exposure of the water to the light. Both outlets can be used, but it s not necessary to do so. If an outlet is not to be used it should similarly be capped with a Fernco type fitting. It is also recommended that valves, whether it be a knife or ball type, be utilized on the piping going in and out of the RDF. Take care the inner diameter is the same as the inner of the piping Overflow pipe Inside the drum there is a vertical open ended pipe, which functions as an overflow pipe. In the event of a rain storm or some other occurrence causes changes to the outside water level, the overflow pipe will assist in keeping water levels within tolerances. The vertical pipe is not glued so you can adjust very fine or cut into the desired length you wish. Also when working on the drum and a lot of dirt swims out you can remove that pipe easy for cleaning inside before it goes to your bio filtration unit. Tap water supply Overflow Outlet 1 Outlet 2 A tap water coupling is already provided with the system. Do not replace this connector because it transitions with piping inside the filter. The max pressure the drum is designed to handle is 60 psi. The ideal water pressure to operate the drum is 45 psi, with a capacity of 2 gallons
per minute. Approximately 1 quart of tap water is consumed during a cleaning cycle. There must be adequate water pressure for the drum filter to properly operate. Narrow and/or long tube or piping may result in a reduction of water pressure from the water source during action. 1 2 1 Tap water Release part 2 then connect to your water supply Waste basket. A big advance is that the waste basket is also fully operational under water level (patented). This will result that we can make it work with a much higher percentage of the mesh surface than anybody else. This will result in a higher flow Waste Basket At starting it can be even almost 100 percent.
This results in a much smaller filter with the capacity of a bigger one. As soon as the washing of the mesh is starting we have a popup cylinder who is opening the waste outlet in 70 mm diameter. Normally only the spray water is used to remove the dirt but actually that is very few. At the sides of the waste basket you find a lot of 6 mm holes who will help removing the dirt more quick. In the beginning it starts exploding. Those 6 mm holes can easy be opened or closed. So in this way we can also adjust the refreshing rate of the pond water. Blanket weed. For many the biggest problem The waste basket is provided at one side to pick up the blanket weed leaves etc. After a period of time and even in wintertime you will see the water is clear but still we are collecting algae. This algae when not washed out automatically will feel like butter so fine it is but also smelling like hell. This always has to be removed by hand Depending the circumstances maybe once per month in wintertime and with exploding blanket weed in summer every day. But now we really can collect it at this place and not all around the whole drum inside. Waste line Aeration Pipe Waste pipe Take care the waste outlet has to be aerated so the main waste valve cannot stick by suction pressure under it. Depending on the length of your waste line, it may be necessary an opening in the waste line to permit air to enter the waste line. The reason
for installing an aeration opening is that the waste drain within the filter is covered and opens during the cleaning cycle using a valve. A closed waste line may create a vacuum that prevents the valve from opening the waste drain cover. A 6mm or 1/8th tube installed into the waste line in proximity to the filter will prevent a vacuum from developing. UV lamp The 75 watt UV lamp provides two important functions. Function 1 is the eradication of algae. The UV penetration inside the RDF is more effective than inside traditional tubes. The 75 watt UV lamp is capable of servicing a 20000 gallon pond and has a two year use life. Function 2 is the eradication and prevention of bacterial growth on the drum screen. Bacterial growth on an RDF screen can interfere with its normal operation. Utilizing the UV does away with the need to clean the screen with chemicals, like acid.
You ll notice the UV lamp is mounted very close to the screen which helps ensure that screen remains clean from the outside as well the inside You can purchase UV lamp directly from your dealers. Installing UV lamp UV lamp can be installed very easy. Actually the drum filter becomes the UV housing now. At the side of the drum filter you already find the connecting device. Take out the plug and you can install the quartz glass tube from that side. After inserting the quartz glass tube, take out the plastic gloves for handling the UV bulb. Never touch the bulb with your fingers because dirt and oil may be transferred to the bulb causing the bulb to prematurely fail. Insert the bulb into the pin openings of the socket. Screw the base into socket on the RDF and ready you are. NEVER operate the UV light outside the RDF. Radiation emitted from the bulb is dangerous to your eyes and should not be directly viewed. Please take the end of the glass tube will not touch the drum after filled water Cleaning before start It s important to ensure that no dirt in the water line enters the cleaning nozzles as it could potential clog them. Therefore, remove the spray bar by unscrewing it. Turn on the water and install the float tube. Let water run through the water pipe inside in the filter. Reinstall the spray bar. Nozzle Bar Opening and closing the drum There is a removable panel for the drum that permits access to the inside of
the drum and waste tray. By lifting the two handles at the sides of the drum from under the locking pins, the panel can be taken out. To close the drum, insert the top of portion of the panel into the groove and then lower the locking arms onto the pins. Push both handles beneath the pins to secure. Drum Lid Handle Adjusting the drum. The drum is equipped with a valve that permits you to control the rotation speed of the drum. The valve is controlled by a small blue lever that s located on the water piston. A slow rotation speed is to be needed. For optimum results as it also permits more time for the screen to be washed while maximizing filter cake filtration on the drum screen. This permits the removal of finer particles from the water column. A cleaning cycle only takes approx. a quarter of the drum and no more. The rest of the inner drum will clog some more as we need for finer filtrating the smaller parts. So standard it starts at 60 micron and stops at the end about 10 microns. If you speed up the drum this will raise but never make more than half a drum for security reasons. Speed Adjusting Knob At the end it is so fine that 10 micron dirt even will not pass anymore and when you swipe you only see clouds and no debris so in this way the RDF
filter can go down to even ten microns without any extra pump resistance. This makes the RDF filter unique (patented) and also it can be used in swimming pools Swimming pools In a 30.000 gallon swimming pool we can make it work with a regulated rpm BLUE-ECO pump of max 240 watt. In praxis already 150 watt max will do. So less noise, less power, less money, more green. In the wintertime we even go down to 20 watt or lower to have a constant flow of the water. Also by night in the high season. Never switch it of but let it run on 30 percent of your power. This will upraise your quality of the water.
