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
