FILTER
When backwashing, if the filter does not produce expected results, it is
necessary to clean or replace foam media. This should be performed at
least once a season. However, this is not a rule for pond and outdoor
environments vary thus more frequent cleaning may be required.
• Unplug the Terminator™ UVC Sterilizer.
• Turn the pond pump off.
• Disconnect the barbed fitting from the filter.
• Flip out safety lock and remove lid retainer clamp.
• Remove the lid of the filter. Handle with care. The UVC bulb and quartz
sleeve is made of glass.
• Remove the intake and output flares. (See Part List on page 3).
• Remove and rinse foam pads. Replace them if necessary.
• Remove the bio-chamber and rinse well with pond water only.
Biological media beneficial bacteria will be killed if tap water is used to
rinse.
• Remove and rinse pre-filter foam pads. Replace them if necessary.
• Rinse and clean the filter body.
• Place the filtering media back in their original locations. Replace intake
and output flares.
• Replace o-ring and verify that it is clean. We recommend using a small
amount of silicone lubricant on the o-ring to ensure a proper seal.
• Secure lid with lid retainer clamp. The lid retainer clamp must be
aligned so that the notches in the top of the clamp fit under the intake
and discharge port.
• Filter is ready to use. See installation instructions.
UVC BULB
• Follow all the safeguards and warnings of the manufacture.
• Before doing any maintenance on the UVC sterilizer, the power supply
and water supply must be disconnected.
• Only in rare situations does the quartz sleeve ever have to be
removed. If necessary loosen screws carefully, then remove the quartz
sleeve. If excess force is used the quartz sleeve will break. After
removed, use a soft clean cloth to gently remove any excess grim
and/or debris. Reassemble using a small amount of silicone lubricant
placed on the o-ring prior to sliding it into the main body of the UVC
sterilizer.
