CAUTION!
Material damage possible due to power
surges
Should the pump be connected to the
mains power supply in parallel to inductive
consumers (such as solenoid valves,
motors), inductive power surges can
damage the control when it is switched off.
– Provide the pump with its own con‐
tacts (Phase) and supply with voltage
via a contactor relay or relay.
–
Should this not be possible, then
switch a varistor (part no. 710912) or
an RC gate (0.22 µF/220 Ω, part no.
710802) in parallel.
CAUTION!
Warning against illegal operation
Observe the regulations that apply where
the unit is installed.
Capacity too low
The liquid end valves can be disturbed by
vibrations.
–
Secure the metering pump so that no
vibrations can occur.

Installing the hose line
Fig. 3
1. Assemble the metering pump on a
storage tank or a bracket using screws
and U-washers (Ø 6 mm).
2. Cut the pressure hose to the required
length.
3. Pull the union nut (5) and clamping ring
(4) over the hose line (6).
4. Push the shortened hose end up to the
