Introduction
The Hydrocontrol is an electronic manometric
switch with integrated dry run protection and a
return flow inhibitor. It serves to convert a sur-
face pump in an automatic domestic water sys-
tem.
Prior to starting up the Hydrocontrol (hereafter
referred to as manometric switch), please read
these operating instructions and those for the
pump, which is used together with the Hydrocon-
trol, very carefully. This is the prerequisite for
safe work and fault-free handling.
Always keep operating instructions readily at
hand and also pass these onto subsequent
users.
The symbols used in these operating instructions
are explained below:

For fuse protection, a line safety switch 10
A and an earth leakage circuit breaker with
nominal residual current of 10/30 mA must
be installed.
The specifications for power supply voltage
and voltage type on the rating plate must
correspond with the data of your power
network.
Only use a 3 x 1.5 mm
2
extension cord, of

ited.
The manometric switch does not work, if
the extraction point is higher than 15 m
above the manometric switch.
The allocated pump must not take up more
than 10 A and must not fall below pressure
of 1.8 bar and must not exceed 8 bar.
