MAINTENANCE & CLEANING
For permanent installations to the mains supply, it is necessary to conform to the regulations of the local
electricity authority and this would include the use of a metal or plastic conduit to protect the cable.
Attention has been drawn to the fact that special rules may exist concerning the installation of your
pond UVC (i.e. local building regulations).
This UVC must not be used in swimming pools, or areas where people are in contact with the water.
Always disconnect the mains electricity supply whilst the equipment is being installed, repaired, maintained
or handled. Consult a qualified electrician if in any doubt about wiring this product to the mains supply.
Electrical/Safety
UVC Warning: Caution: Dangerous Ultra Violet Radiation. The rays from the UVC lamp are
harmful to eyes and skin.
Always turn off UVC electrical supply before any maintenance.
To protect unit from flooding, leave a minimum 5cm showing above ground level to protect UVC electrics.
Never immerse unit in water.
Locate unit 1m minimum from pond edge to ensure the filter cannot fall in.
Your Midipond filter has been designed to need
a minimum of maintenance.
When the filter system is first installed filter
cleaning may be increased for a period until
the back log of accumulated pond waste is
removed.
Routine maintenance
Hydroscreen chamber
When the hydroscreen chamber fills with water and overflows into the foam chamber, remove and wash
out under a tap. It is not necessary to remove the metal screen from its carrier for routine cleaning.
Graded foams
The filter foams only need cleaning when the foam chamber is full with water and the water layer above
the foams starts to significantly overflow the partition into the cartridge chamber.
25% of the pumps input may be allowed to overflow the partition into the cartridge chamber, prior to cleaning.
Cleaning the foams before the foam chamber overflows will result in decreased filter efficiency as the
foams work most effectively when partially blocked.
Foams may be cleaned vigorously under a running tap or hose.
Adding Interpet 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.
Professional ceramic bio media
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 maintain a healthy pond.
