Each float cable is composed of three leads: BLACK-BROWN-GREY. The GREY lead is not used and its
insulation is to be provided by the user.
5.6 Connecting the pipes:
5.6.1 Input:
connect the tank input pipe, identified by the special adhesive label, to the waste connection
pipe with a PVC coupling DN 110; ensure that the couplings are sealed with glue for pressurised
PVC pipes.
For 200-280
l
tanks it is possible to have a second input using part 119a (Coupling DN 50).
5.6.2 Delivery:
connect the delivery pipe (two for FEKAFOS 550
l
– FEKAFOS 280
l
DOUBLE) to the
sewage network with the 2” threaded gas fitting (and/or Sleeve 63x2” – 118 –), ensuring that the
couplings are sealed.
For ease of maintenance and to prevent backup, when the tank is situated below the level of the
sewage network, it is advisable to use a no return valve and an interception valve, as in the example
of installation on page 26, both supplied on request; it is recommended to install a siphon, especially
if a no return valve is not being used.
5.6.3 Ventilation: tank ventilation must always be ensured.
Connect the ventilation mouth (coupling DN 50) to a ventilation duct leading outside the premises.
Avoid horizontal lengths in the ventilation duct.
5.7
Before replacing the cover on the tank, make a test connection with clean water, after having
connected the pump to the mains.
5.8
In systems provided with a reflux kit, before starting the electropump, vent the kit, momentarily
lifting the pump out of its seat.
6. ALARM SYSTEM
For the parts references, see the diagrams on pages 23-24-25.
Either of two alternative alarm systems may be installed.
-
Pre-set system; connected to the pump control panel, without reserve charge, inefficient in the event of
black-out of the power supply.
- AS1 system; independent and with a reserve charge of 10 hours (supplied only on request).
