en ENGLISH
When using universal swivel cou-
plings (bayonet couplings), only
use versions with an additional
securing ring to ensure safe seal-
ing.

6. Initial Operation

6.1 Setting pilot pressure
Set the pilot pressure before initial operation. See
section 9.4.
6.2 Installation
The device must be positioned on a horizontal, flat
surface that is suitable for the device weight with
water filling.
To avoid vibrations, the device should not be
bolted on but rather should be positioned on a
resilient base.
The place of installation should be well ventilated
and protect against weather influences. Protect
against frost - see section 8.2.
For operation in garden ponds and
swimming pools, the device must
be installed in a flood-proof loca-
tion and secured against falling in.
Additional statutory requirements
must be taken into consideration.
6.3 Connecting suction line
Caution! The suction line must be installed
such that no mechanical or twisting forces
are exerted on the pump.
Caution! Use an intake filter to protect the
pump against sand and contamination.
Caution! The check valve is absolutely
necessary to prevent the water from draining
when the pump is switched off. We recommend
the installation of check valves at the intake
opening of the suction hose and at the suction
connection (4) of the pump. Depending on the
model, a check valve may already be integrated
(see section 13. Technical Specifications).
Seal all screw-coupling with thread sealing tape.
Leaks result in air intake and reduce or prevent the
water intake.
The suction line should have an inside diameter of
at least 1" (25 mm); it must be kink- and vacuum-
resistant.
The suction line should be as short as possible
because the longer the line length, the lower the
conveying capacity.
The suction line should rise uniformly towards the
pump to prevent air inclusions.
A sufficient water supply must be guaranteed and
the end of the suction line should always be under
water.
6.4 Connecting the discharge line
Caution! The discharge line must be installed
such that no mechanical or twisting forces
are exerted on the pump.
Seal all screw-couplings with thread sealing tape
to prevent water discharge.
All components of the discharge line must be pres-
sure-resistant and installed correctly.
Danger! If non-pressure-resistant compo-
nents are installed, or assembly is incorrect,
8
the discharge line can burst during operation. Inju-
ries are possible if highly pressurised fluids are
ejected!
6.5 Connection to a pipe network
To reduce vibration and noises, the device should
be connected with flexible hose lines to the pipe
network.
6.6 Mains connection
Danger! Risk of electric shock!
Never operate the device in a
wet environment and only under
the following conditions:
- Connect only to an earthed outlet
that is properly installed, earthed
and tested.
- Mains voltage, mains frequency
and fuse protection must corre-
spond to those stated in the
'Technical Specifications'.
- The device must be supplied via
a residual-current device (RCD)
with a rated residual current of
max. 30 mA.
- The electrical connections must
not be under water and must be
located in a flood-proof area. The
connections must be splash-
proof for outdoor use.
- Extension cables must have
sufficient conductor cross
sections. Unroll cable reels fully.
- National installation specifica-
tions must be observed.
6.7 Filling pump and suction
Caution! In the case of a new connection,
water loss or air intake, the pump must be
filled with water. Operation of the pump without
water filling will destroy it!
- Unscrew water filling screw (5) including gasket.
- Slowly pour in clean water until the pump is filled.
- Screw in water filling screw (5) with gasket again.
- Open the discharge line (open water tap or spray
nozzle) so that air can escape during suction.
- Switch on the device (see section 7.).
- When water emerges evenly, the device is ready
for operation.
Note: The suction line does not need to be filled
because the pump is self-priming. Depending on
the length and diameter of the line, however, it may
take some time until pressure is built up. To
shorten the suction time: install a check valve at
the intake opening of the suction hose and fill the
suction line too.
7. Operation
Caution! The pump and suction line must be
connected and filled (see section 6.).
Caution! The pump must not be allowed to
run dry. There must always be sufficient
conveying medium (water) available.
If the pump is blocked by foreign bodies or the
motor is overheated, a protective circuit shuts
down the motor.
7.1 Using the device
Pump
(device designation P...)
Functional principle: the device runs as long as the
on/off switch (8) is activated.
Danger! If the discharge line is closed, run the
pump for a maximum of 5 minutes because
otherwise overheating of the water in the pump can
cause damage.
1. Insert mains plug.
2. Turn on at switch (8).
3. Open the discharge line (open water tap or
spray nozzle).
4. Check that water emerges!
5. When work is complete, turn off the device at
the switch (8).
Domestic water system
(device designation HWW...)
Functional principle: the device switches on when
the removal of water causes the water pressure to
fall below the switch-on pressure; it switches off
again when switch-off pressure is reached. The
pressure vessel contains a rubber bellows, which
is under air pressure (pilot pressure) when deliv-
ered; this permits the removal of small volumes of
water without the pump starting up.
1. Insert mains plug.
2. Turn on at switch (8).
3. Open the discharge line (open water tap or
spray nozzle).
4. Check that water emerges!
8. Maintenance
Danger! Prior to all servicing:
- Unplug mains cable.
- Ensure that the device and connected accesso-
ries are depressurised.
- Repair and maintenance work other than
described in this section should only be carried
out by qualified specialists.
8.1 Regular maintenance
- Check device and accessories, in particular,
electrical and pressurised components, for
damage and repair if necessary.
- Check suction and discharge lines for leaks.
- If the conveying capacity decreases, clean intake
filter and filter element (if installed) and replace if
necessary.
- Check the pilot pressure of the pressure vessel
(10) (depending on features) and increase it if
necessary (see section 9.4 Increasing pilot pres-
sure).
8.2 Danger of frost
Caution! Frost (< 4 °C) destroys the pump
and accessories as both always contain
water!
- If there is a danger of frost, disassemble pump
and accessories and store in frost-free condi-
tions (see following section).
8.3 Removing and storing device
- Turn off at switch (8). Unplug mains cable.
- Open the discharge line (open water tap or spray
nozzle), allow water to drain off completely.
- Completely drain the pump (7) and vessel (10)
by:
- unscrewing the water drain screw (1).
- Remove suction and discharge lines from
device.
- Store device in a frost-free room (min. 5 °C).

9. Troubleshooting
Danger!
- Prior to all servicing:
- Unplug mains cable.
- Ensure that the device and connected accesso-
ries are depressurised.
9.1 Pump is not running
• No mains voltage.
- Check on/off switch, cables, plug, socket and
mains fuse.
• Mains voltage too low.
- Use an extension cable with sufficient
conductor diameter.
• Motor overheated; motor protection relay
tripped.
- After cooling the pump will switch on again.
- Guarantee sufficient ventilation, keep air slots
free.
- Observe maximum supply temperature.
• Motor hums, but does not start.
- With the motor switched off, insert a screw-
driver or similar object through the air slots on
the motor and turn the fan impeller.
