INSTALLATION
The drumfilter must be placed on a firm, flat (level!) surface. The drumfilter is suited for gravity- and pump fed applications.
Default position of the level switch is for gravity application (level switch in drum chamber).
For gravity application the installing height (above the water level of the pond ) is minimum 10 cm from the top of the waste gutter (see
drawing). The top of the waste gutter is the physical limit for the water level (when the pump is not running). Installing below this level
will cause water loss over the edge of the waste gutter! A safe limit is 1-2 cm below the edge of the waste gutter. Keep in mind that there
will be moving water in the pipe system when you stop the pump that causes some “wave” effect in the water level. These small water level
fluctuations can cause some water loss over the edge of the waste outlet.
The drumfilter is fitted with 3 Ø110 mm inlets. If
you do not use all 3 of them we recommend to
keep the middle inlet closed. The left and right
inlets will not enter the drum directly but first hit
the walls of the inlet chamber which allows a more
quite flow into the drum. When you use all 3 inlets
we recommend to use the middle inlet for the pipe
with the least flow (like the skimmer or the bottom
drain that is installed the farthest from the
drumfilter). We strongly recommend the use of a
slide valve for every incoming pipe to regulate the
flow individually.
TIP
: It is also advisable to have a direct slide valve
to waste on every incoming pipe. This way you can
flush the bottom drains direct to waste without
burdening the rest of the filter system (see
example gravity application).
