7 .5 .2 Tank inspection
Inspect the tank, check for possible deposits, the presence of grease and
foreign bodies. Thoroughly clean the tank and remove foreign bodies.
7 .5 .3 Disassembling and inspection of the compression chambers
1. Unscrew (1 screw), unlock and lift the pressure switch from the cover.
2. Check that the funnels are not obstructed (grease, faecal matter etc.).
Clogged compression chambers indicate that the device has not been
properly maintained. It is recommended to clean the device at least every
6 months.
3. If necessary unclog the compression chambers.
7 .5 .4 Reassembly
During reassembly, observe the following points:
To reassemble the pump, observe the rules applicable to engineering goods.
Do not over-tighten the screws on plastic parts (risk of breaking the plastic)
and clamps.
Clean all disassembled parts and check their wear.
Replace damaged or worn parts with original spare parts.
Ensure that the sealing surfaces are clean and the O-rings are properly
installed.

7 .5 .5 Tightening torque

The tightening torque for screws and clamps is 2 ± 0.1 N.m
NOTE
After every flood, the pumping station should be inspected.
NOTE
After an incident, subject the pumping station to functional test
and visual inspection.

8 . Incidents: causes and solutions

Table 7: Messages and faults:
ANOMALY DETECTED CAUSES PROBLEMS
• Water level detection
Flashing red alarm LED
system faulty
• Clogged vent pipe
Steady red alarm LED
• Clogged drain line
• Blocked or out of order
pump
• Discharge too high or
excessive inflow
• Mains failure
LED off (SANICUBIC ®1)
• Faulty electronic board
Flashing LED for mains
power (Others)
NOTE: If both switches are
lowered (off position), abnor-
mal situation, the card will be
in alarm mode when power is
restored
SOLUTIONS
• Consult SFA after-sales
service
• Check that air flows freely
in both directions in the
vent pipe
• Go over the installation
again
• Consult SFA after-sales
service
• Check the electrical system
• Consult SFA after-sales

Solutions
The size of the pumping station
is insufficient for these operating
conditions.
Open the valve to the maximum.
Check the pumping station's vent
pipes
Remove deposits in the pump and/
or piping.
Check if the wheel turns freely without
blocking. If necessary, clean the pump.
Check the electrical installation (and
fuses).
The engine automatically restarts
after cooling.
Clean the sump tank. In case of grease
deposits, make sure there is a grease
trap.
Clean the check valve.
Check the flexible pipe connections.
Check the level sensor. Clean or replace
it, if necessary.
Replace the capacitor
With the connection, inverse 2 power
cable phases (5 wires).
