ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Imperatively 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!
– 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 immedi-
ately 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.
– Note electronics only JPM ¾" – 1¼":
Memory electronics are found under the
lid of the handwheel. It uses an acoustic
alarm as a reminder, that every two
months the filter needs to be back-
washed, maximum backwash intervals.
Activation:
• Lift the lid of the handwheel.
• Insert the two batteries in the battery
compartment. Use 1.5 V (AAA) batteries
supplied.
• Replace the handwheel lid.
• You can test the functionality by
pressing the
RESET
-key in the lid of the
handwheel.
5.2 Pressure Setting
To change the factory-set pressure of 4 psi.
– Loosen countersunk screw on the hand-
wheel of the pressure reducer.
– Turn the hand-wheel in a clockwise
direction = pressure increase
– Turn the hand-wheel counter-clockwise
= pressure reduction
– The pressure setting-range is recom-
mended between 2 psi and 6 psi.
– Open a tap downstream of the PROMI
as a pressure relief and the set pressure
can be read.
– As soon as the desired setting-range is
reached, re-tighten the countersunk
screw on the hand-wheel of the pressure
reducer.
– The fixing of the countersunk screw on
the handwheel of the pressure reducer is
recommended to lock in the setting.
