• If not using the discharge shutoff valve, attach the
appropriate multi-hose adapter to the backwash port.
Then, attach a section of tubing that can discharge the
water to your yard or garden before rotating the backwash
valve 90 degrees to the “CLEAN” position (Ex. 19).
NOTE: The valve can be a little stiff to turn if it hasn’t been
moved in a while. Do not use tools which might crack
the handle.The valve assembly can be removed from the
lid for cleaning and lubrication with silicone grease. We
recommend doing this if the valve becomes very stiff to
turn.
• Plug in or restore power to pump.
• Backwash approximately 1-3 minutes depending on how
dirty the filter is or until the water begins to come out clear.
• Unplug or turn off power to pump. If using the discharge
shutoff valve, fully close the valve. If using the backflush
cap, remove the multi-hose fitting and replace the
backflush cap.
• Turn the valve 90 degrees clockwise to the “RUN”
position.
• Plug in or restore power to pump. Press the “RESET-
CLEAN” button once you have completed the cleaning
operation.
UV Operation
• The UltraKlean Pond Filter with UV prevents/eliminates
single-celled algae commonly referred to as green water.
The UltraKlean Pond Filter includes a bulb saver timer
feature that extends the life of the UV bulb by allowing you
to set the operating time for the bulb based on the water
quality conditions in the pond.
• Setting the UV Timer – If the pond water has a planktonic
algae bloom (green water) then use the “Select UV Time”
button to set the UV timer to the 24-hour setting (always
on). In general the cleaner and clearer the pond water,
the less the UV light needs to be operated. Once the
green water is cleared you can reduce the UV timer to
the 12-hour setting (on for 12 hours/off for 12 hours) or
the 6-hour setting (on for 6 hours/off for 18 hours). If you
notice the green water beginning to reappear, you can
increase the UV light operation time until the green water
clears.
• Bulb Life – For effective clarification, the UV bulb
should be replaced after 12 months of continuous use
when operated on the 24-hour setting. The bulb saver
feature can extend the life of the bulb up to 2 years
when operating on the 12-hour setting or 4 years when
operating on the 6-hour setting.
NOTE: even though the UV bulb still emits light, it may
have lost its effectiveness at clarifying if the recommended
operating duration has been exceeded.
• Cleaning/Replacing the Quartz Sleeve – A dirty quartz
sleeve will reduce the effectiveness of the UV bulb. Debris
and mineral deposits can be cleaned using a mild acid
like white vinegar or a non-abrasive calcium, lime, or rust
remover with a soft bristled brush or sponge.
To access the quartz sleeve:
1. Unplug both the pump and the UltraKlean Pond Filter.
2. Once the clips are released (Ex. 20), use the lid and
tank tabs to gently lift the lid assembly free from the
canister (Ex. 21). The lid may be difficult to lift due to
the pressure inside the filter. Loosening one of the
plumbing fittings will reduce the pressure, making it
easier to remove the lid.
3. Remove the set screw holding the UV light tube in
place under the UV ballast (Ex. 22).
NOTE: use a properly-sized Phillips screwdriver small
enough to grip the set screw.
4. Twist counterclockwise and lift to remove it and expose
the quartz sleeve (Ex. 23).
5. The quartz sleeve can now be accessed for cleaning or
replacement.
6. If replacing or removing the quartz sleeve, remove the
threaded plastic collar that locks the quartz sleeve over
the water-tight seal and remove the quartz sleeve
(Ex. 24).
