Troubleshooting - AquaScape 2000 Mode D'emploi

6. Grip the base of the UV bulb and pull it free from the
four-pronged socket.
7. Replace UV bulb in reverse to the order it was removed.
• Use a clean lint free cloth to wipe off any dirt or smudges
on the bulb prior to reinstalling the control panel into the lid
of the filter. Also, make sure there is no standing water or
moisture inside the quartz sleeve or on the bulb prior
to reassembly.
• Winter Storage – If your pond is subject to freezing, the
UltraKlean Pond Filter should be shut down and stored
indoors or in a frost-free location. If you've buried the
canister body we recommend removing it from the ground
to avoid possible damage. When disconnecting the tubing
from the filter, the threaded fittings should be removed
without the need for any tools (be careful not to lose the
flat rubber washers).

Troubleshooting

Reduced Water Flow
• All pressure filters, even when new and clean, will reduce
water flow from pump by approximately 50%. It is
recommended to use the largest diameter tubing possible
(up to 1½ inch diameter) in order to achieve maximum
water flow rates.
• Make sure to trim off smaller sections of multi-hose
adapter to avoid flow restriction. See page 7 for more
information.
• The UltraKlean BioBalls could be clogged with debris and
require a backwash cleaning.
• Pump or plumbing may be clogged. It may be necessary
to clean the pump cage screen and impeller.
UV Light is Not On
• Cycle timer is not set to the 6-hour, 12-hour, or 24-hour
setting
• Power to the UltraKlean Pond Filter has been lost. Check
to be sure it's plugged in and the ground fault breaker is
not activated.
• UV internal bulb connection may be loose. Disengage the
UltraKlean Pond Filter ballast, and check to make sure the
UV bulb's four-pronged base is seated securely into the
receptacle inside the lid. See page 10 for more information.
Also, when replacing the quartz sleeve, be sure the collar
is snug as tightening the collar activates the safety switch
for the UV light.
• UV bulb could be beyond its life expectancy.
Replace UV light.
