INSTALLATION
Before proceeding with the installation and the starting of the RE-START & GO, it is
essential to prime the pump correctly. The controller should be installed always in
a vertical position (fig. 1 and 2). Avoid outlet non-return valves and not install
taps between pump and device.
The following accessories are recommended:
flexible with a disassembling link for network connection, protecting the set from
possible flexion charges and vibrations. Ball valve which permits the isolation of
the pump from installation.
WARNING!
Install always pumps which develop a maximum pressure higher of at least 2,5
bar than the minimum start-up pressure set.
Water column height Start-up pressure adjustment
20 m
25 m
For increase the minimum start-up pressure execute the following operations:
Make the pressure inside the plant let down till to reach the start-up pressure de-
sired
Turn on the right the adjustment screw housed on the rear (fig.3) until the pump
starts. At this point the device is ready for working.
ATTENTION!
If the adjustment screw is too heavy to turn, it is necessary let the pressure in the
plant down and proceed for attempts in minimum start-up pressure regulation.
ELECTRIC CONNECTION
RE-START & GO can control directly single-phase pumps up to 1,1 kW and absorp-
tion up to 20(8)A - 220/240V.
For single-phase pump of upper power or three-phase, it is necessary the use of
an auxiliary contact as indicated in fig.4.
WARNING!
Bad connections may spoil the electronic circuit. The installation must be done by
a reliable electrician, and in plants with IAn=30mA emergency cut-out.
