MAINTENANCE

7.1 General information / Safety instructions

Work performed on the pumping station by unqualified staff. Risk
of injury!
w Repairs and maintenance must be performed by specially
trained staff
w Observe the safety and basic instructions.
Pumped fluids and secondary consumable materials that are har-
mful to health. Dangerous for people and the environment!
w Pumping stations used to discharge fluids that may be harmful
to health must be decontaminated.
If necessary, wear a mask and protective clothing.
w Observe current legal provisions for the discharge of fluids
harmful to health.

7.2 Maintenance and inspection operations

Work on the pumping station without adequate preparation.
Risk of injury!
w Properly stop the pumping station and secure it against inad-
vertent operation.
w Close the inlet and discharge valves.
w Drain the pumping station.
w Close any auxiliary connections.
w Allow the pumping station to cool to room temperature.
Pumping stations must be maintained and repaired to ensure the proper
disposal of wastewater and to detect and eliminate malfunctions at an early
stage.
The proper functioning of pumping stations must be checked by the user
once a month by observing at least two operating cycles.
The inside of the tank should be checked from time to time and deposits,
especially around the level sensor, should be removed, if necessary
Maintenance of the pumping station must be performed by qualified staff.
The following intervals should not be exceeded:
• 3 months for pumping stations for industrial use
• 6 months for pumping stations for small communities
• 1 year for domestic pumping stations

7.3 Maintenance contract

As with any technical, high-performance equipment, SANICUBIC® pumping
stations must be maintained to ensure a sustainable level of performance. We
recommend you take out a maintenance contract with a qualified company
to carry out regular inspection and maintenance work. For more information,
please contact us.

7.4 Emergency service with a single pump

NOTE
If emergency service must be ensured during maintenance and
inspection work, perform the following steps.
1. Close the valves on the inlet and discharge sides.
Warning: The incoming feed for inlets must be minimised while performing
maintenance
2. Turn off the power supply.

7.5 Checking the hydraulics of each motor

• Make sure its blade and plate are not blocked or damaged.
• Make sure the turbine rotates freely
• Make sure the hydraulic parts are clean. Clean them if necessary.
In case an motor is not working properly, it is possible to "disable" the use of
this motor by switching the corresponding "switch" on the main card to in-
dicate the absence of the corresponding motor. The card will only work with
the valid motor - SW1: switch 1 and 2 for motor 1 (left) and 2 (right).
7.5.1 General information
Inspect the tank, check for possible deposits, the presence of grease and
foreign bodies. Thoroughly clean the tank and remove foreign bodies.
7.5.2 Disassembling the motor
1. Unscrew the motor hatch from the tank cover (10 screws).
2. Use the handle to gently lift the motor. If the defective motor is to be
returned to the manufacturer, the pumping station can provide a minimum
service with one single motor.
3. Unscrew the screws of the faulty motor from the hatch.
4. Put the hatch back in position.
7.5.3 Disassembling and inspection of the compression chambers and
level sensors:
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 of the level sensors
Warning: Do not grease the level sensors' O-rings before reassembly.
1. Fully insert the level sensor in the compression chamber.
2. Screw the level sensor onto the cover.
7.5.5 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.

NOTE: If both switches are
lowered (off position), abnor-
mal situation, the card will be
in alarm mode when power is
restored
