6.5.7 Connecting the power supply
Earth cable should be about 10mm longer
than the other two, so that it will not be
disconnected accidentally if pulled.
The power supply cable must be covered
by the silicone sheath (01) supplied. The
silicone sheath must be fastened with the
corresponding cable tie (02).
All the conductors relating to the MAIN-IN,
HH-PUMP and WIPER terminals must be
separated from the other safety very low
voltage circuits (ES1 circuits).
The disconnection of a wire must not
compromise the protection against
electric shocks.

Connect the power supply terminal (J1, 6.4 Board
description, page 8). Connection must be carried out
using a cable of adequate section.
Nominal section of the cables used: from
0.2mm² (24AWG) up to 2.5mm² (13AWG).

6.6 Pump installation
Be very careful not to start the pump when
the tank is empty.
We recommend filling the tank with water
at ambient temperature. If using the pump
at temperatures below 3°C (37.4°F) add
some glass cleaner antifreeze liquid to the
water.
The antifreeze liquid will cause irreparable
damage to the germanium windows. In
this case, do not use anti-freeze liquid, but
add ethanol in a 20% solution.
If present, the level switch enables
automatic stoppage of the pump.
6.6.1 Adjustment of the level switch
position
In the equipped versions, the position of the level
switch (01) and the counterweight (02) must be
adjusted.
