Installation and operating instructions Liftson M-2V-208
CAUTION! Risk of damage!
The use of other valves than those from the Salmson accessories can lead to malfunc-
tions on or damage to the product.
Afterwards, connect the pressure pipeline directly to the gate valve (flange piece, flexible
hose section, flat gasket and connection elements included).

7.3.2 Inlet ports
Install the inlet pipes so that they can run empty by themselves.
Main inlet DN 100/DN 150
Only insert the main inlet pipe (DN 100 or DN 150) in the tank at the marked surfaces.
• Measure position. Pay attention to the minimum connection height for the inlet in the tank
and the perpendicular entry into the tank (90° ± 5°). The horizontal notch lines in the tank
provide orientation for the connection heights 180 mm and 250 mm (pipe centre). Other
infinitely variable connection heights are possible.
NOTE: Inlet ports below 180 mm are possible, but can cause a corresponding backflow in
the inlet pipe. In this case, when the pump run-time is set low, there is the danger that the
pipe no longer empties completely due to the low water level drop in the tank, which can
cause deposits to form inside it (see 8.2.2 Setting the pump run-time).
• Select the position and pipe installation so that surge-like water entry and strong air entry
are avoided as much as possible.
To avoid the transfer of forces and vibrations bet-
ween the unit and the pressure pipeline, the con-
nection should be flexible. Also, keep a distance
between the flange piece and the pressure pipe
(Fig. 5).

The hole sawed with the keyhole saw must lie within the
surfaces here (Fig. 6).
CAUTION! Risk of damage!
Connecting the inlet pipe outside of the
marked surfaces can lead to leakage, malfunc-
tions and damage to the product.
