7. Installation of tank
Place the tank in such a position that the cover
can be removed for periodic inspection.
To eliminate the transmission of noise to the
building,
- make sure that there is at least 10 mm
clearance between the tank and a wall
- place the tank on an anti-vibration material.
Even though a non-return valve is fitted in the
pump discharge port, the discharge pipe must be
taken above the backflow level (i.e. main sewer
level). The pipework from this point must be made
with pipe sizes of at least 40 mm nominal
diameter (DN 40).
We recommend that the discharge pipe travels
first vertically and then horizontally in order to
utilize the pump pressure in the vertical part of the
discharge pipe.
In order to use the connection in the tank cover
(d), knock out the disk and use the DN 40 or
DN 50 fitting.
The fasteners supplied with the lifting station are
to be used for wall- or floor-mounting. See "b" in
the figure below.
