With regard to an ATEX 95 zone 22 certification, see the special remarks.
Never touch rotating or moving parts of the machines with hands or feet.
Never reach with hands, tools or other parts over the inflow or hopper in the area of the auger while the ma-
chine is running.
In handling slurry, always remember that the gases produced by the slurry are highly toxic and explosive in
combination with oxygen. Open flame, light checks, spark creation and smoking are therefore prohibited!
When using the retention or alternating retention method, special care must be taken in the area of the
opened sliding gates to the pre-pool before the main tank or to cross channels due to the formation of gas-
es. In addition, special care is required at stirring and withdrawal points while the stirring machines or
pumps are active!
Keep the machine clean to decrease the risk of fire!
Always ensure sufficient ventilation when working with slurry!
When working with biologically active materials in connection with the FAN press screw separator or con-
nected components, the decomposition of these materials can lead to the production of life-threatening
gases, especially in enclosed spaces. Always ensure sufficient supply and exhaust ventilation and/or ap-
propriate protective clothing before entering such areas.
DANGER
In addition to the mechanical dangers of moving parts or parts under pressure, the opera-
tion of slurry handling machines also poses risks in connection with gases produced by
liquid manure. These gases (carbon dioxide CO2, ammonia NH3, hydrogen sulfide H2S, me-
thane CH4) can result in poisoning as well as explosions.
Especially when operating mixers, stirring machines, recirculation systems, pipe nozzles
and slurry aeration systems, care must be taken that no gases can flow into the stall from
exterior tanks or containers (install siphons or sliders).
Sufficient forced ventilation of the stall area must be ensured while handling slurry in the
stall area.

3FUNCTION DESCRIPTION
The FAN press screw separator serves for separating solid-liquid-fiber suspension with relatively low
solid matter content and no foreign bodies such as metal parts, stones, wood or rags into solid and
liquid fractions. As a compact device, it combines the functions of two separators, specifically the func-
tions of a screen and a press.
The FAN press screw separator is designed for sustained operation outdoors. It operates unimpaired
in a temperature range of 0-40 °C; in event of freezing temperatures, it must be ensured that the sepa-
rator is cleaned completely each time before being taken out of operation. Conditions of high humidity
(e.g. locations near to the coast) and extreme sunlight as well as installation in areas at risk to explo-
sion (gas: max. zone 2 (G)) require special designs for the gears and motors. Consult the manufactur-
er concerning such designs.
When selecting the feed pump and the overflow line, make certain that the separator is operated under
no pressure.
In the inflow area, the mixture is drained of water via gravity inside the screen. The interior auger
transports the pre-drained material horizontally toward the solid outlet. Along the last section of the
transport path, the auger presses out additional liquid, which escapes the separator through the screen
as effluent. The required contact pressure is applied to the escaping solid by a system consisting of a
cap loaded by a weighted lever.
The separating result depends mainly on the viscosity and on the composition of the media. Users of
the FAN separator have with this machine many options for optimizing the separating result.
The throughput can be increased be selecting a larger screen gap width.
The residual moisture in the separated solid decreases as the contact pressure of the output
regulator is increased.
The solid matter content in the separated liquid can be reduced with a smaller screen gap width.
The degree of solid separation is improved by smaller screen gap widths.
More information about the configuration options can be found in section 7 “Initial Start-up”.

4.1 INSTALLATION DIAGRAM
4.2 CONDITION OF THE FAN PRESS SCREW SEPARATOR UPON DELIVERY
The FAN PSS was developed by the company FAN Separator GmbH. The separator is delivered as a
unit, including installed electric motor, on a pallet. The inflow T-piece and the ventilation pipe are en-
closed separately for easier transport and must be installed before the initial start-up.
You must connect the geared motor and the vibrator (if included) of the separator to the power supply
of the optionally available switch cabinet and connect this to the electricity supply. It is recommended
that the corresponding electrical control for the separator or for the separator and the FAN submersed
motor pump be purchased from FAN since it will be already adapted to the corresponding drive mo-
tors.
Connecting the supplied hoses, if included, to the inflow and discharge connections of the machine
completes the installation of the FAN press screw separator.
DANGER
Work on electrical and electronic components of the system may only be per-
formed by a trained electrician or otherwise appropriately trained personnel under
the guidance and supervision of a trained electrician in accordance with the ap-
plicable electrical and electronic regulations.
4.3 REQUIRED TOOLS
Special tools are not required for setting up the FAN press screw separator.
Standard tools for assembly and electrical tools are required for assembly, setup and disassembly.

Fig. 4-4 illustrates a suggestion for determining the size of the separator setup location.
It is very important that a clearance of at least 1500 mm or more is ensured in front of the mouth piece
of the separator. This clearance is required to remove the auger and the screen for maintenance. It
must be possible to remove the auger and the screen for regular inspections.
Width of the setup area: No less than 2000 mm
Length of the setup area: No less than 4000 mm
The surrounding clearance around the separator should be at least 1 m.
Handrail height of the setup area: No less than 1000 mm
Make sure that the mouth piece and the functioning of the separator can be clearly seen from the
switch cabinet. (It must be possible to watch the solid cake and its discharge speed.)

4.8 COMPLETE SYSTEM
The complete system of the press screw separator also includes the material supply and discharge
handling.
The incoming material can be delivered by pump or from an elevated tank by means of gravity. Be-
cause the pump delivery rate cannot be precisely determined, an overflow is absolutely required in
order to protect the separator from an overload.
The pump should be designed to slightly ex-
ceed the capacity of the separator, but the
pressure on the separator should not exceed
2 m water column [0.2 bar]. A higher pressure
would damage the seal in the separator
In order to obtain a homogeneous mixture of
solid and liquid, a stirring machine is required
when supplying the slurry via a pump or from
an elevated tank.
It is very important that the supply of material to
the separator is always controlled by the switch
cabinet.
The correct selection of the pump, the stirring
machine and the supply and disposal lines is
critically important.
When supplying the press / auger separator
from an elevated tank by means of gravity, a
flow regulator may be required in some circum-
stances to limit the pressure on the separator.
In this case, an overflow is not required.
The effluent should be disposed of via an open
(and thereby ventilated) drain channel or col-
lected in a drainage pit and then pumped out in
order to avoid generating a suction effect on
the separator. The ventilation is required be-
cause otherwise particles are drawn into the
screen gap and remain stuck there, blocking
the open screen surface and impairing the
function of the separator.
The separated solid can be piled up and trans-
ported away as needed, brought away on a
conveyor belt or disposed of by container or
truck.
The supply line available with the FAN press screw separator as an accessory is a reinforced yet flexi-
ble tube. This reinforced tube is resistant to negative pressure. Ventilation openings can be added to
the inflow line through the connection of a breather pipe to the T-piece. The ventilation is required for a
pump with a very high pump capacity since the high flow speed in the overflow line would otherwise
produce a siphon effect that would limit the supply to the separator and impair the separation process.

The separator must be set up so that the solid can be freely
discharged. There must be a corresponding height difference
between the solid discharge point and the ground. The volume
of the cone of discharged material can be determined based on
the setup height.
The overflow line for the raw medium as well as the drainage
line of the separated medium should drain without pressure into
the corresponding storage tanks.
The overflow line should be run without a “siphon” in order to
avoid a lifting effect and to ensure good separator throughput
(see also section 14 “Problems - Troubleshooting”).
Avoid winding, dipping and twisting of the pipeline and use tub-
ing that is resistant to negative pressure.
4.8.1 Standard Setup
With the standard execution of inflow –oscillator with inflow tube –
the inflow tube DN100 is vertically integrated in the inflow flange.
(separator housing on top)
For supply with a pump, see Fig. 4.8, a T-piece available on option
must be connected with the vertical inflow tube. The supply line is
connected to the T-piece on top. To do so, you need a hose di-
mensioned DN100. Coupling pieces for the hose lines as well as
bows are available as accessories.
The overflow line is connected to the T-piece laterally. To do so,
you also need a hose dimensioned DN100.
The ventilation tube is to be mounted to the overflow line at the T-
piece. It avoids an underpressure in the separator when the medi-
um makes a vacuum in the return line.
The ventilation pipe shall project the supply and/or the overflow line
by approx. 1,5 m. Connection: 1 ½” external thread.
It is also possible to mount two T-pieces available on option, see
Fig. 4.9. The supply line is connected to the bottom T-piece lateral-
ly. The overflow line is connected to the top T-piece laterally and
the vertical line is used for ventilation. (To do so, you also need
hoses dimensioned DN100.)
For supply from an elevated tank, see Fig. 4.10, the supply line is
connected directly to the inflow tube with a hose DN100. In this
case, no overflow is needed, however, a ventilation tube must be
mounted in the supply line.
4.8.2 Alternative Setup
Alternatively an oscillator with hopper (Fig. 4-11) or only a big hop-
per (Fig. 4-11) can be mounted on the supply side. These compo-
nents are available on option.
In this case neither an overflow line nor a ventilation line is needed.
4.8.3 Drainage Line
The drainage line is connected to the outlet tube DN100(PSS1.2-
520, PSS1.2-780, PSS5.2-520) DN125(PSS3.2-520,PSS3.2-780,
PSS3.2-1040,3.3-780,PSS5.2-780,PSS5.2-1040) DN125 on the bot-
tom of the separator housing. (see Abb.4-12)

NOTE
If no FAN pump is installed, the pump for supplying the separator should have a pump
rate of at least 35 m³/h for PSS1.2-520/PSS3.2-520/PSS5.2-520 (50 m³/h for PSS1.2-
780/PSS3.2-780/PSS3.3-780/PSS5.2-780 and 70 m³/h for PSS3.2-1040/PSS 5.2-1040 )
since the capacity of the separator otherwise cannot be fully utilized. To keep pressure
losses due to pipe friction low, the pipes should have a diameter of at least 100 mm (4").
5ELECTRICAL CONNECTION
The electric motor is equipped with a terminal strip. Like all electrical connections, the external motor
control must be connected properly by a qualified electrician.
DANGER
Work on electrical and electronic components of the system may only be per-
formed by a trained electrician or otherwise appropriately trained personnel under
the guidance and supervision of a trained electrician in accordance with the ap-
plicable electrical and electronic regulations.
WARNING
Fuses do not protect the motor from overloads; they only protect the electrical
supply lines or switching systems from damage in event of a short-circuit.
The electric motor must always be protected with a motor protection circuit breaker that must be set to
the rated current shown on the type plate depending on the motor wiring. Only motor protection circuit
breakers certified according to the following standards may be used: IEC, UL, CSA.
WARNING
Set the motor protection circuit breaker to the correct value, never above the max.
rated current according to the type plate.
It is recommended that the corresponding electrical control for the separator or for the separator and
the submersed motor pump be purchased from FAN since it will be already adapted to the correspond-
ing drive motors.
WARNING
Ensure the correct rotation direction of the auger shaft when making the electrical
connection!
In forward motion, the auger shaft turns counter-
clockwise
(as viewed from the output regulator toward the geared
motor).
If this is not the case, two of the current-carrying conduc-
tors at the geared motor connection or in the switch cabi-
net must be swapped.

5.1 SETUP AND OPERATION OF THE MOTOR
The motors in the standard design are suitable for operation up to a maximum ambient temperature of
+40 °C (104 °F) as well as an elevation of up to 1000 m above sea level.
Conditions of high humidity (e.g. locations near to the coast) and extreme sunlight as well as installa-
tion in areas at risk to explosion (gas: max. zone 2 (G)) require special designs for the gears and mo-
tors. Consult the manufacturer concerning such designs.
The motors must be set up to allow unimpeded inflow of fresh air and dispersal of warm air. Removal
of the fan blade and the fan housing or enclosing the motor in a housing are prohibited since the sup-
ply of cooling air would be reduced in both cases. This would cause the motor to overheat.
DANGER
Before making changes or inspecting the motor or switch cabinet, the machine
must be disconnected on all sides and all poles and secured against reactivation!
Always keep the switch cabinet closed!
DANGER
It must be noted that a pressed EMERGENCY OFF button does not provide any
protection against unauthorized starting of the machine.
5.2 CONDENSATE HOLE
We recommend a condensate hole on motors that are subjected to high temperature fluctuations or
extreme climatic conditions.
DANGER
A motor protection circuit breaker or a protective device with overload relay must always
be installed to protect the motor winding (for the explosion-protected separator design,
suitable motor protection must be selected). Fuses do not protect the motor from over-
loads; they only protect the electrical supply lines or switching systems from damage in
event of a short-circuit.
5.3 INSTALLATION WITHOUT SWITCH CABINET
If the FAN press screw separator was delivered or ordered without a switch cabinet, a few
basic rules must be followed in controlling the separator; otherwise, the warranty is void:
The motor must be equipped with electrical protection to prevent impermissible current loads
exceeding the rated current on the type plate.
Operating the press screw separator without an inflow of material must be prevented by means
of electrical control since dry running would otherwise result in increased wear on the screen
and auger, which would significantly reduce their service lives. For this reason, the separator
should be started up along with the start of the medium supply and stopped between 1 to 2
minutes after the medium supply is stopped.
