2.7 Design of pump and motor
The submersible pump is based on multi-stage and centrifugal design.
A mechanical seal protects the motor against the hydraulic part of the pump.
The SE type model are fi tted with a lateral suction support to allow the
connection of fl oating or fi xed suction fi lters.
The other models contain a suction strainer on the pump base.
The motor is equipped with an overheating protection which automatically
switches the motor off if it overheats. After suffi cient cooling, unplug the
mains plug and plug it in again - the pump restarts.
The pump reacts to a lowering of the water level and switches on and off
automatically.
The integrated electronics protect the pump from running dry.
If there is no withdrawal within 24 hours, the pump switches on automatically
for 2-3 minutes. This is to prevent the pump from blocking.
3 Application/use
CAUTION! Possible damage of the pump.This pumps are intended for use
with water only.
3.1 Intended use
Series Extract FIRST submersible pumps are suitable for the application areas
following:
• For not very deep wells, tank, cistern.
• Pumping and water distribution for:
• agricultural use (watering, irrigation),
• Pumped fl uids: non polluted, potable, cold, rain waters.
3.2 Improper use
The pump is not suitable for continuous use, e.g. for the operation of foun-
tains. (Continuous operation > 2 hrs reduces the lifetime of the pump).
The pump must not be used for emptying swimming pools.
The pump must not be used in drinking water applications.
4 Transport and storage
When receiving the material, check immediately that there has been no dama-
ge during the transport. If any defect has been stated, take the required steps
with the carrier within the allowed time.
CAUTION! If the delivered material is to be installed later on, store it in a
dry place and protect it from impacts and any outside influences (humidi-
ty, frost etc...).
Handle the pump carefully so as not to damage the unit prior to installa-
tion.

DANGER! Bodily injury!
Installation and electrical work in compliance with any local codes and by
qualifi ed personnel only
WARNING! Bodily injury!
Existing regulations for the prevention of accidents must be observed.
WARNING! Electrical shock hazard!
Dangers caused by electrical energy must be excluded.
National Electrical Codes, local codes and regulations must be followed.
5.1 Installation
CAUTION! Possible damage of the pump
Do not transport, hang or suspend the pump by the cable.
• The pump must be installed in frost-free place.
• Fix the safety rope in the middle of the handle in the superior part of the
pump.
• Connect the delivery pipe work.
• Use rigid metal pipes to hang the pump.
In a well
• Secure the pipes with brackets at the top of the well.
In a tank
CAUTION! Possible damage of the pump!
Only operate the pump in a vertical position!
• Fix the supply cable without constraint to the delivery pipe with the appropri-
ate bindings.
• Lower the pump and level it so that it is always immersed in water, maximum
depth: 5 m and freely suspended.
CAUTION! Possible damage of the pump!
Only operate the pump in a vertical position!
• Ensure that the well diameter is always constant and allows a free lowering of
the unit.
• Centre the pump in the middle of the well, tank or cistern.
• Ensure that the pump, the electric cable and the safety rope, in operation,
could not rub against the well sides or any other obstacle.
NOTE: Make sure that the pump is not in direct contact with the ground! It
could otherwise cause noise.
12 WILO SE 2022-10 DIN A5
English

• In their fi nal operating position, the suction strainer or the suction fi lter (SE
version) must have a minimum distance of 200 mm to the well bottom/tank
bottom.
• Ensure that the minimum water submersion is always 150mm over the suction
suction strainer of the pump when the pump is running (Fig. 2, 3, 4).
• The SE-type model can be installed out of water, because the motor is cooled
by the fl uid (Fig. 4).
NOTE: The pump has a valve for automatic venting in the upper part of the
housing (Fig. 6, Pos. A). This valve allows the pump to prime in a very short
time.
In the case of dry well installation of the SE version and generally when the
upper casing is not completely covered by water, a small amount of water
will leak out at this point. This is not a malfunction!
Because of the way the automatic venting works, dry installation is only
recommended outdoors (Fig. 4)!

A Automatic venting
B Pressure setting; factory preset - DO NOT CHANGE!
• For outdoor installation, protect the delivery pipe work, the electric box, val-
ves, fl ap, electric controls from frost.
• If a fl oating tapping device (suction fi lter with hose connection) is used take
care to ensure that the length of the hose is adapted to the structural condi-
tions of the cistern (see Fig. 5). To prevent air from entering, the fi lter basket
must not reach the surface of the water.
5.2 Hydraulic connection
CAUTION! Possible damage of the pump
During the use of SE pump, fill the section hose with water before starting
the pump.
The Extract FIRST pumps are not self-priming.
• The pipework diameter cannot be inferior to the pump’s one on rigid threaded
steel pipework or a semi rigid polyethylene high density pipework.
• In the case of a semi rigid pipework the pump must be supported by a safety
rope fi xed to the carrying handle situated on the pump top.

5.3 Electrical connections
WARNING! Electrical shock hazard
The electrical connections and the inspections have to be done by a quali-
fi ed electrician and comply with the applicable local standards.
The power supply of the pump must include a circuit having a residual
current difference device (earth fault breaker) acting at no more than
30mA.
In case of cord damaged, make it replace by a qualifi ed electrician.
• Control the kind of current and the network voltage.
• Observe the specifi cations of the pump nameplate.
WARNING! Do not forget to connect the earth.
NOTE: The single-phase pumps have an integrated overcurrent protection.
• The pump with single-phase motor is cabled and has an integrated thermic
protection.
Do not connect the pump if:
• The connection cable is damaged.
Have the connection cable replaced by a qualifi ed electrician or the customer
service.
• A standalone inverter is in use.
Stand-alone inverters are used in autonomous power supplies, e.g. solar power
supply, and can generate overvoltages. Overvoltages can destroy the pump.
• A multiple plug socket or power strip is in use.
• An energy-saving plug is in use.
This reduces the energy supply to the pump and the pump may heat up too
much.
• Operation on start-up controls.
The pump is not suitable for operation on a frequency converter or a soft start
control.

Inadequate voltage or volta-
ge drop
Check voltage on start-up, an
insuffi cient cable cross-sec-
tion can cause a voltage drop
that prevents the motor from
operating normally.
Motor power cable break Measure the resistance
between phases. Re-assem-
ble the pump if required and
check the cable.
Motor protection ON Check the current set on
thermal relay and compare it
to the mentioned value
Important: if it trips repeti-
tively, do not insist (look at
the cause). Forcing the unit
to operation can damage the
motor (by overheating) in a
very short time limit.
