6.8 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.
6.8.1 Adjustment of the level switch
position
In the equipped versions, the position of the level
switch (01) and the counterweight (02) must be
adjusted.
