2. Compare the values with those of the rating plate.
3. Check the connection of the power supply to the earth.
4. Check the connection of the power supply to a ground fault circuit
interrupter (GFCI).
5. Check the connection of the power supply to a circuit breaker with
adapted current rating.
6. Check the proper operation of the motor by pressing the forced
activation button. If abnormal, make sure the pump is not clogged.
7. Perform a functional test over several cycles.
8. Check the correct installation and state of wear of the exible cou-
plings.
9. Check the proper operation and eectiveness of the alarm device.
10. Check the proper operation and seal of the shut-o valves and non-
return valves.
11. Shut down the sewage pumping station properly and secure it
against unintentional operation.
12. Close the inlet valves.
13. Close the discharge valve.
14. Let the sewage pumping station cool down to room temperature.
15. Inspect the hydraulic parts and the cutting blade. Clean them if
necessary. See 8.4.1 Checking the hydraulic.
16. Check the inside of the collecting basin: see 8.4.3 Checking the
collecting basin.
WARNING
Presence of cutting blades.
Risk of pinching, cutting or amputating ngers or other
body parts.
ÖEven when switched off, take care when handling a
pump.
ÖKeep away from moving parts.
17. Advise and/or train operating personnel.
8.4 CONTROL OPERATIONS
Follow the instructions in order.
1. Empty the basin by pressing the Manual activation button on the
control box. If the pump does not work, empty the basin manually.
2. Close the inlet and discharge valves.
IMPORTANT
The incoming feed for inlets must be minimized while performing
maintenance.
3. Turn o the power supply.
4. Unscrew the cover (3 screws).
WARNING
Fall of the sewage pumping station.
Risk of injury from crushing.
Risk of damage to the station.
ÖDo not lift the station by the pressure switch handle.
ÖTo work on the unit, it is possible to lift the Sanipit by
the motor handle and the discharge/vent columns.
8.4.1 Checking the hydraulic
1. Unscrew the motor from the support (10 screws).
2. Use the handle to carefully lift the motor out of the outlet elbow
slide.
3. Check that the blade and its plate are not blocked or damaged.
4. Check that the rotation of the impeller is free.
5. Check that the hydraulic parts are clean. Clean them if necessary.
8.4.2 Disassembling and inspection of the compression
chambers
1. Unscrew the pressure switch (6 screws).
2. Use the handle to carefully lift the pressure switch.
3. 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.
4. If necessary unclog the compression chambers.
8.4.3 Checking the collecting basin
1. Unscrew the support (16 screws) and remove it.
2. Check the inside of the basin regularly and clean the switch.
3. Hose down the basin to loosen deposits from the basin walls and
remove any foreign matter.
8.4.4 Reassembly
During reassembly, observe the following points:
• Respect the rules applicable to mechanical constructions.
• 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 prop-
erly installed.
In particular, when reassembling the pump:
1. Check that the outlet elbow ring (red part) is properly seated in the
slide.
2. Lower the pump and orient it so that the pump bottom engages
correctly in the slide rail.
