4.2.5 Installing a diaphragm pump
Make sure that the weight from the inlet,
outlet and vent pipes does not rest on the
tank. Long pipe sections and valves must
be supported.
You can use the optional, manually operated
diaphragm pump for draining the tank before service
or maintenance. To enable service or maintenance,
we recommend that you fit an isolating valve. The
tank has two outlets for 1 1/4" and 1 1/2" pipes. The
flexible connecting piece for 1 1/2" is supplied with
the lifting station.
1. Drill the outlet port with a 20 mm drill.
It is necessary to drill the outlet as it may have
been filled with tank material during the moulding
process.
2. Connect the outlet to the pipe for the diaphragm
pump by means of the flexible connecting piece
and hose clamps.
3. Connect the diaphragm pump to the collecting
line.
The outlet pipe of the diaphragm pump must have
a bend above the backflow level which is often the
street level. Ask your local authorities.
