Hydraulic Connection - SFA Sanicubic GR Manual De Instalación De Uso

• Wastewater other than those mentioned above, for example, of ar-
tisanal or industrial origin, must not be discharged into the pipes wit-
hout prior treatment.
• The floor of the room must be able to support the load of the entire
installation.
• In underground rooms or rooms where there is a risk of water in-
filtration, it is recommended to place a drainage pump in a manhole.
4.2 FITTING
• A hook in the ceiling above the set-up site of the lifting unit faci-
litates assembly and potential maintenance and repair work on the
pump.
• Prior to assembly, all construction and connection measurements
should be checked and compared with the dimensions of the sys-
tem. Here you should pay special attention that the constantly
downward-inclining supply connection never lies lower than the in-
flow height of the collecting tank.
• Fit the pumping station on the bare ground and level it with a spirit
level.
• To avoid any risk of the pumping station floating, attach it to the
ground using the mounting kit provided.

4.3 HYDRAULIC CONNECTION

NOTICE
 The pumping station must not be used as a control
point for piping.
 Prop up the pipes upstream from the pumping station.
Make connections without constraints.
 Use suitable means to compensate for thermal expan-
sion of the piping.
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.
1. Choose the connection openings to use.
Maintain a minimum slope of 3% on the inlet pipes to ensure proper
flow to the plant.
2. To connect the inlet pipes, saw the opening of the inlet pipe to be
used. The rear inlet of the double lift system must be opened with a
hole saw or a blade; do not use a hammer!
3. Then insert the inlet pipe into the opening.
IMPORTANT
Preferably use the upper inlet.
If it is not possible to use the upper inlet, use the rear inlet located
250 mm from the floor.
As a last resort, the case of connection to the side inlets located 180
mm from the floor is possible under the strict condition that the fol-
lowing measures are observed:
1. Raise the axis of the pipe to 250 mm above the floor of the lifting
station, either by lowering the floor under the station (fig. A) or by
raising the floor under the connected sanitary installation (fig. B).
Fig. A :
Fig. B :
2. Change the axis of the pipe as close as possible to the station.
NOTE
It is imperative that the level sensor is set correctly so that the pump
casing is completely filled for immediate pumping. See 5.2.
NOTICE
Insufficiently filled pump housing.
Danger of de-priming!
 Preferably use the upper inlet.
NOTE
Using inlets lower than the 250 mm inlet can lead to dirt deposits in
the inlet lines and in extreme cases to blockage of the line. Therefore,
the higher inlet should be used whenever possible.
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
discharge pipe in a «loop» so that its base, at the highest point, is
located above the back-flow level.
Fit a shutoff valve behind the check valve.
A bend DN 50, 90° is mounted as standard on the horizontal pressure
discharge of the pump, which ends in a vertical direction drilled with
1"/ internal thread.
The installation of the non-return ball valve(s) included in the scope of
delivery in the pressure line of the lifting unit is mandatory
It is recommended to install a shut-off valve behind the non-return
ball valve in order to facilitate maintenance and possible replacement
of the non-return ball valve.
For double lifting units, a Y-pipe with a DN50 pressure outlet (flange)
is included in the scope of delivery.
The pressure pipe must be laid steadily rising and without unnecessa-
ry 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
pressure. The ventilation must be completely free and air must
flow in both directions (no diaphragm valve fitted).
• Connect the station's ventilation pipe Ø75 mm, 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 ope-
ning using the flexible sleeve.
• 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 venti-
lator
 Ventilation must remain free
 Do not block the vent outlet
250 mm
 Do not install an air intake valve (diaphragm valve).
