Point of installation and fastening
The point of installation on the vehicle must
•
be easy to access,
•
be protected from dirt, the impact of stones and
water splash.
•
leave sufficient space for the connection of operat-
ing water, the suction and pressure lines and the
operating water drain.
•
be accessible for maintenance (for regreasing the
grease barrier).
Fasten the machine at the 4 feet (M16 tapped holes).
The machine can be fastened directly onto a suitable
frame. The minimum depth of thread engagement is
23 mm.
Framework must be of sufficient strength to support
machine in operation and while vehicle is driven.
The four fastening points (machine foot supports) must
be in exact alignment.
For dimensions and weights, see chapter 1. "Technical
data".
The machine must be adequately earthed.
An equipotential earth bonding strap should
be securely fastened between the machine
body and a suitable point on the vehicle
frame.
Ensure that the machine and all ancilliaries
are earthed in accordance with BS5958 Pt1:
1991;
'Control of undesirable Static Electricity'.

Connections and piping
For regular service of the liquid ring pump the suction,
pressure lines, operating water supply, and water drain
line must be connected to the machine
The various possibilities of the suction and pressure
line connections are illustrated in figure 4.5 for ma-
chines of clockwise and counterclockwise rotation.
The suction and pressure line, respectively, can either
be connected on the A side or B side. The same ap-
plies to the operating water supply, the drain line and
the venting line.
As regards piping, the minimum pipe diameters in the
table below are recommended.
