Installation
Fig. B Determine the location of the filter. Provide a dry sheltered place (not in direct sunlight) and a stable flat surface
with sufficient space around for maintenance.
• NOTICE! A gravity filter must be installed at pond level or above. Recommendation is to build a base for the gravity
filter system to sit upon, using the correct materials, connectors, pipes etc Ask for advice from your pond specialist
or engage an installation company.
• The height of the minimum/maximum water level of the filter is marked on the partition panel of the filter (i).
Place the filter at such a height that the maximum water level in the pond never exceeds the maximum water
level in the filter.
• Place a pump suitable for dry installation (max. pump capacity 17,500 L/h) "behind" the filter.
• Connect the pump to one of the filter outlets (b) (ø 110 mm) using a flexible socket. Close the other inlet with the
cap provided.
• NOTICE! The pipe connections (ø 110 mm) on the filter can NOT be glued, use flexible rubber sockets.
• Connect both inlets (a) (ø 110 mm) to the pipes to the bottom drains and skimmer in the pond using flexible
sockets.
• Connect the drain channel (c) (ø 110 mm) to a drain (e.g. sewer) using a flexible socket.
Fig. C Unscrew the plastic coupling from the bottom of the intake pipe (l) of the spray system.
• Remove the rinse pump (k) from its packaging and screw the plastic connector into the top of the rinse pump by
hand.
• Place the hole under the intake pipe (l) of the spray system and tighten the lock nut firmly.
• Place the capacitor box of the rinse pump in a safe and dry place near the filter.
• NOTICE! The rinse pump on/off switch is located on the side of the capacitor box, make sure it is switched on when
you put the system into operation.
Fig. D Connect an air pump (min. 1200 L/h, not supplied) to the quick-connection (q) of the filter using a ø 12 mm
reinforced air tube (not supplied).
• Remove the protective cap from the air stone inlet (e) and connect the transparent air tube (p).
• Install the immersion UVC (u) (check the separate user manual of the UVC for correct installation).
• Check that the floater is pushed all the way down, this is the factory default setting. The floater is easily adjusted
in height by pulling it up or pushing it down.
• Fill the pond with water, the water runs through the bottom drains to the filter. Due to the law of communicating
vessels, the water level in the filter will be as high as in the pond. Stop filling as soon as the maximum water level
(i) in the filter is reached.
• In the meantime, check all connections, pipes, etc. for any leaks.
Fig. E Place the control box (h) in a safe and dry place near the filter.
• Connect the cable (f) of the floater (s) with the cable (g) of the control box. This DMX connection is watertight and
therefore sometimes difficult to fit (if required, squeeze the outside of the mating plug (f) while inserting the
other plug). Tighten the union nut hand-tight.
• Insert the plugs of the rinse pump (k), immersion UVC (u), electro motor (m) and pond pump (d) into the
appropriate sockets on the control box. See markings on the control box. Provide the cables with drip loops so
that no water can run along the cables into the control box.
• Plug the control box into the socket, making sure there is a drip loop here as well.
