Proper use
• This filter is intended in stationary use as a prefil-
ter for the suction-side connection to well water,
rainwater and process water.
• It may not be used to provide drinking water or to
convey food items.
• Explosive, combustible, or aggressive materials
or substances which are hazardous to health and
fecal matter may not be conveyed.
• The filter is not suitable for commercial or indus-
trial use.
• Any other use is improper. Unforeseeable dam-
age may result from improper use, alterations or
the use of parts that have not been checked and
approved by the manufacturer!
Connection
Note: All screw connections must be sealed
with screw thread sealing tape (e. g. Teflon
tape); leaks cause air intake and reduce or
prevent water intake.
The filter is installed between the pump and the suc-
tion line.
– Screw the outlet nozzle of the filter to the suction
nozzle of the pump (pipe connection: 33,3 mm
(G 1")). Observe installation direction: the out-
let nozzle of the filter is marked [OUT] on the top.
– Screw the inlet nozzle of the filter to the suction
line of the pump (pipe connection: 33,3 mm
(G 1")).
Commissioning
Before commissioning, the filter must be filled with
water so that the pump can take in.
