General
NOTE Select or set a contact water meter in such a way that,
at max. installation output, the control pulses are not
< 5 pulses/sec. Calculation of the contacts, see Section
on "Mode/Contact input"
The control for the Oxiperm installation may process at
a max. rate of 50 pulses/sec. If a value greater than
50 pulses/sec. is calculated, use a different contact
water meter!
NOTE If the pressure at the injection unit is < 1 bar, a
pressure retention valve must be installed (pos. 16). A
pressure retention valve may not, however, be used in
system installations with an internal rotary pump, as
this pump only generates an increase in pressure of
approx. 5mWS.
NOTE For the dosing pumps DMI with Plus3 system, ensure
that the container is always underneath the dosing
pump and the suction line is positioned in a downwards
direction, so that the chemicals can easily flow back via
the return pipe into the container (recommended L =
min. 200mm, see diagram).
