4.3.1 Inlet
IMPORTANT
It is recommended that you mount check valves and stop valves on
the inlet pipes. These must be mounted so that they do not hinder
disassembly of the pumping station.
NOTE
All piping connections must prevent the propagation of noise and be
flexible.
The piping is supported.
Maintain a minimum slope of 3% on the inlet pipes to ensure proper
flow to the plant.
Insert the inlet pipe into the opening.
4.3.2 Discharge
NOTICE
Improper fitting of the discharge pipe.
Leaks and flooding of the installation room!
The pumping station must not be used as a control
point for piping.
Do not connect other drain pipes to the discharge pipe.
To prevent the risk of back-flow of water from the sewer, install the dis-
charge pipe in a «loop» so that its base, at the highest point, is located
above the back-flow level.
A bend 90° is mounted as standard on the horizontal pressure dis-
charge of the pump, which ends in a vertical direction.
The installation of non-return ball valve(s) in the pressure line of the
lifting unit is mandatory.
It is recommended to install a shut-off valve behind the non-return
valve in order to facilitate maintenance and possible replacement of
the non-return ball valve.
The pressure pipe must be laid steadily rising and without unnecessary
jumps in a bend above the backflow level and then steadily falling to
the sewer connection. Pipe and fittings must be supported with pipe
clamps or brackets, if necessary.
4.3.3 Ventilation
IMPORTANT
According to the recommendations of EN 12050-1, it must be
equipped with a vent above the roof. The pumping station must
always be ventilated so that the tank is always at atmospheric pres-
sure. The ventilation must be completely free and air must flow in
both directions (no diaphragm valve fitted).
• Connect the station's ventilation pipe, either directly to the building's
ventilation pipe or installed separately and directed above the roof.
• The connection should be made vertically to the ventilation opening
DN100.
• The connection must be smell-proof.
• The vent pipe must not be connected to the vent pipe on the inlet
side of a grease trap.
NOTICE
Insufficient ventilation.
Risk that the pumping station will not work!
Do not connect to a mechanically controlled ventilator.
Ventilation must remain free.
Do not block the vent outlet.
Do not install an air intake valve (diaphragm valve).
4.4 ELECTRICAL CONNECTION
DANGER
Disconnect electrical power before working
on the unit!
DANGER
Electrical connection work performed by an unquali-
fied individual.
Risk of death by electric shock!
The electrical connection must be performed by a qual-
ified and licensed electrician.
The electrical installation must meet the current stand-
ards in the country.
• All electrical installations used must comply with IEC 60364/
NF C 15-100, which means that sockets must, for example, be equipped
with earth terminals.
• The electrical power supply must be protected with a high sensitivity
circuit breaker set to 30 mA upstream of the control unit, or to prevent
a failure of the control unit when the residual current circuit breaker re-
sponds, one residual current circuit breaker per pump must be installed
between the control box and the lifting station.
This connection must be used exclusively for the Sanicubic SC power
supply.
• Please observe the regulations of EN 12056-4.
• The external protection must generally be 3-pole mechanically inter-
locked with automatic circuit breakers. This ensures complete discon-
nection from the mains and prevents 2-phase operation.
• All electrical devices such as control system, alarm transmitter
and socket must be installed in dry rooms so that they are protected
against flooding.
• The motor can overheat due to overload. In case of overheating, nev-
er touch the hot surfaces on the motor.
WARNING
Hot surface.
Burn Hazards!
Never touch the surface of the motor housing without
protective equipment.
The wiring diagram of the lifting station is available in the instructions
manual fo the control box and should be kept there to facilitate the
work of the maintenance and service personnel.
5. COMMISSIONING
5.1 PREPARATION
• Before commissioning, all connections have to be checked again for
correct installation. It must have been made sure that the safety regu-
lations have been complied with.
• Install and connect the control box: refer to the installation instruc-
tions supplied with the control box.
• The control must be installed in such a way that the blue pneumatic
hose for the level control can be laid rising steadily from the lifting unit
to the connection at the switch box.
NOTICE
Pneumatic hose with downward slope, low points.
Control line kinked or squeezed.
Control line extended.
Risk of condensation !
Risk of signal disruption !
Follow the installation rules above and in the control
box manual.
