Always observe the chapter “Intended use”!
5.1 Commissioning
Before starting up (initial putting into service
or startup after maintenance work),
fill the
filter with water and vent !
– To this end, after installation the filter is
filled with water by opening the upstream
shut-off valve.
– The filter is now at the same pressure as
the water system.
– The enclosed air must then be imme-
diately removed from the filter in order to
avoid damage to the installation caused
by pressure surges. The filter is vented
by means of backwashing (see chapter
“Discharging the backwashing water”).
– After backwashing and venting the filter
is ready for use.
5.2 Functional description
Water flows through the built-in rotary flange
into the filter. A coarse filter (JSY-LF
1½" –
2") prevents large dirt particles from getting
into the fine filter. These large dirt particles
cannot be removed by the backwashing
equipment. The water flows through the fine
filter from the outside inwards. The filtered
dirt is retained by the fine filter screen. The
adhering dirt is visible through the transpar-
ent filter bell. The filtered water then leaves
the filter via the built-in rotary flange.
JSY-LF ¾" - 1¼":
The filter contains a silver-plated suction
pipe unit located at the sieve insert of the
protective filter for an optimum prophylactic
germ protection. If the prophylactic germ
protection shall remain durably, the suction
pipe unit has to be replaced after one year
by trained personal. The function of the filter,
however, is unlimited.
