Assembly of the MOT-7
MOT-7 consists primarily of two main components: the filter unit and the pump unit.
The pump
unit’s task is to supply the untreated water from available water sources, to transport it
to
the filter unit, and to produce the needed system pressure for filtration.
Choose the
location for the set up where the filter unit cannot be submersed in untreated water
and the surface is
dry and stable.
Maximum static suction lift of 5 meters may not be exceeded.
The water quantity that can be expected is represented on the graph on the
next page. The
quantities noted are based on new, or newly cleaned, filter elements. As the filter
elements
become dirtier, the flow rate also decreases accordingly.
Intervals between cleanings can be influenced positively with the appropriate placement of
the
suction hose. Placing the hose directly under the surface of the water. Placing the hose on
the bottom of the water
source should be avoided.

Water bacteria concentration
•
Nutrients
In muddy ground, bacteria can multiply quickly, thanks to an outstanding supply
of
nutrients. Thus, if at all possible, do not place the intake filter in the mud or slime.
•
Varying water temperatures
Higher temperatures promote the grown of bacteria. Standing and slowly moving
water is warmer at the surface. Deeper water has lower bacteria concentrations.
•
Bacteria concentration
More rapidly flowing water has lower levels because the water churns and becomes
diluted. Be aware that churned-up sand can clog the filter.
