Adding Blagdon Bio Start after filter maintenance will help replenish these
beneficial bacterial populations and is highly recommended during the first
two months of operation when the filter is slowly being colonised.

These will only need very occasional cleaning (once per year), but must be
rinsed in pond water to prevent damaging the beneficial bacteria which help

UVC INSTALLATION
UVC LAMPS & QUARTZ SLEEVE MAINTENANCE
The UVC lamp must be replaced every six months / once a season. It is
recommended that the lamp is replaced and reconnected in the spring.
The Quartz sleeve can become coated in lime scale build up in hard water
areas. This should be carefully removed from the quartz sleeve and cleaned
with a soft cloth.
A wet test must be carried out after maintenance to ensure there are no leaks
before the UVC is reconnected.
WET TESTING THE UVC
IMPORTANT: A wet test of the UVC under operating conditions must be
carried out before the UVC or electrical supply is installed.
Connect the UVC to the Inpond following all installation instructions.
After running for 24 hours check for leaks.
TESTING/REPLACING THE UVC LAMP
1. Unscrew the UVC electronics cover cap.
2. Inspect the UVC cap and Quartz sleeve for water leaks.
3. If there are no signs of leakage reverse the procedure ensuring that the
Cover O-ring is in place.
4. This unit is protected by a micro switch that prevents the UVC light from
illuminating when the cover is removed even if the power is on.
5. In order to check that the UVC lamp is operating see page 19 section 2 on
how to view you UVC lamp.
IMPORTANT: Ensure that the mains supply is switched off and the power
isolated before removing the UVC cover.
