Installation and operating instructions Wilo-DrainLift M1/8
CAUTION! Risk of damage!
The use of other valves than those from the Wilo accessories can lead to malfunctions
on or damage to the product.
If other valves are used, pay attention to the type approval of the non-return valve
according to EN 12050-4, as well as to sufficient pressure resistance (PN10) of the
valves.
Afterwards, connect the pressure pipeline directly to the gate valve (flange piece, flexible
hose section, flat gasket and connection elements included)

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. 6).
