4. Installation and Assembly
Gaskets should be properly lubricated befo-
re the closure valve is installed. Once the clo-
sure valve has been installed, it should be
connected or reconnected to the pressure pi-
ping – be sure that all gaskets are seated
properly.
In order to better meet on-site requirements,
the closure valve is rotatable in 45 degree in-
crements (Illustration 9)
ATTENTION:
➤
The T-section on twin pump lifting stati-
ons should only be installed in the ver-
tical position (see Illustrations 6 and 8).
Installing the closure valve in a non-ver-
tical position makes it impossible to
firmly secure the fastening bolts which
could result in a non-water tight connec-
tion.
➤
The connection from the closure valve’s
outlet to the on-site pressure drainage
pipe should only be done with the inclu-
ded flexible hose connector (see lifting
station installation and operation ma-
nual)
