- Use of spare parts which have
not been tested and approved by
the manufacturer.
- Use of unsuitable installation
materials (fittings, connection
lines etc.).
Suitable installation materials:
- pressure-resistant (min. 10 bar)
- heat-resistant (min. 100°C).
When using universal swivel
couplings (bayonet couplings),
only use versions with an
additional securing ring to ensure
safe sealing.

6. Commissioning
6.1
Installation
The unit must be set up horizontally at a dry
(humidity max. 80 %), well-ventilated site that is
free of atmospheric influences. Ensure that the unit
is positioned on a secure, level and firm base when
full of water. The air vents must not be covered or
suck in dirt. There should be a clearance of at least
5 cm from walls and other objects. Protecting
against frost - see section 8.3.
The device should not be bolted on but rather
positioned on a resilient base to avoid vibrations.
The device must be installed in a
flood-proof location and secured
against falling in for operation in
garden ponds and swimming
pools. Additional statutory
requirements must be taken into
consideration.
6.2
Connecting the suction line
Caution! The suction line must be installed in
such a way 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
essential 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 (10) of the pump. A check valve may
already be integrated depending on the model
(see section 13. Technical Specifications).
Seal all fittings with thread seal tape (approx. 10-
15 windings in the thread direction). Leaks result in
the intake of air and reduce or prevent the intake of
water.
The suction line should have an internal 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 pockets.
An adequate supply of water must be guaranteed
and the end of the suction line should always be
under water. Ensure that the suction line is not on
the ground so that no sand or dirt is sucked in. It is
possible, for example, to use a floating intake as an
accessory.
6.3
Connecting the discharge line
In order to reduce friction losses, the discharge line
should have an interior diameter of at least 1" (25
mm). If using smaller diameters, such as 1/2" then
application problems may arise due to inadequate
ventilation.
Caution! The discharge line must be installed
in such a way that no mechanical or twisting
forces are exerted on the pump.
Note: HWWI..., HWAI... (Pumps with integrated
filter): fill the pump before connecting it (see
section 6.7).
Seal all fittings with thread seal tape to prevent
water leakage (approx. 10-15 windings in the
thread direction).
All discharge line components must be pressure-
resistant and installed correctly.
Danger! The discharge line can burst during
operation if non-pressure-resistant
components are installed or they are assembled
incorrectly. Injuries are possible if highly
pressurised fluids are ejected!
6.4
Connection to a pipe network
The device should be connected to the pipe
network with flexible hose lines to reduce vibration
and noises.
In the case of fixed pipes, it is recommended that
these are laid only rising in the first 2 metres to
ensure optimal ventilation.
6.5
Power supply connection
Risk of electric shock! Never
operate the device in a wet
environment and only under the
following conditions:
- Connect it only to an earthed
outlet that is properly installed,
earthed and tested.
- The mains voltage, mains
frequency and fuse protection
must correspond to those stated
in the "Technical Specifications".
- The device must be supplied with
a rated residual current of max.
30 mA through a residual-current
device (RCD).
- 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. Cable reels must be
fully unrolled.
- National installation
specifications must be observed.
6.6
Setting the pilot pressure (only HWW...,
HWWI...)
Set the pilot pressure before the initial operation.
See section 9.4.
6.7
Filling the pump and suction
Caution! The pump must be filled with water
with every new connection and in the case of
water loss or air intake. Operating the pump
without filling it with water will destroy it! In order to
ensure trouble-free operation, we recommend
sufficient removal of water so that the system is
fully ventilated before initial use.
Note: HWWI..., HWAI... (Pumps with integrated
filter): to fill the pump, remove the filter and
additionally fill it through the pressure connection
(12).
- Unscrew the water filling screw (11) with gasket.
- Slowly pour in clean water until the pump is filled.
- Screw in the water filling screw (11) with gasket
again.
- Open the discharge line (open the water tap or
spray nozzle) so that air can escape during
suction.
- Switch on the device (see section 7.).
- The device is ready for operation when water
emerges evenly.
Note: the suction line does not need to be filled
because the pump is self-priming. However, it may
take some time until pressure is built up depending
on the length and diameter of the line. 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.
A protective circuit shuts down the motor if the
pump is blocked by foreign bodies or the motor is
overheated.
7.1
Electronic functions
Shutting down the pump when the discharge
line is closed (standby):
HWW..., HWA..., HWWI..., HWAI...: The pump
switches to standby mode after a follow-up time.If
the discharge line is closed when the pump is
running (close the water tap or spray nozzle. The
electronics initially monitor whether water flows
through the pump, and if no flow is recognised then
the LED (2) flashes green for 40 or 70 seconds
(depending on model). The pump motor is then
switched off, the pump is on standby, and the LED
(2) slowly flashes green. The pump starts
automatically after opening the discharge line.
P 6000 Inox: the LED (2) slowly flashes green for
20 seconds and then quickly for a further 5
seconds if no water flow is detected. Then the
pump motor is switched off and the LED (2) lights
up red.
Dry run protection:
The LED (2) starts to slowly flash red if the pump
cannot convey water after 20 seconds. The pump
motor stops for 5 seconds (LED (2) flashes red +
green quickly) and then tries convey water for 3
further cycles if no water can be conveyed after a
further 100 seconds. The pump stops and the LED
(1) lights up red continuously if water can then still
not be conveyed.
Putting the pump back into operation: press the
ON/OFF button (3) briefly.
Restart protection:
The device has a factory preset restart protection
function that prevents it restarting unintentionally in
the event of a fault or power failure.
The device does not start up automatically after a
power failure and must be put back into operation
by pressing the ON/OFF button (3).
Note: it is not possible to use watering control
systems or ballasts (timer, Hydromat) when the
restart protection is activated. The restart
protection can be deactivated in all devices (with
electronics) by changing the operating mode.
Changing the operating mode / using ballasts:
Insert the mains plug and press button (3) for
longer than 3 seconds. The LED (2) switches from
green to blue. The pump can now be repositioned
and connected to the ballast. Returning to "normal
mode": insert the mains plug and press button (3)
for longer than 3 seconds. The LED (2) switches
from blue to green. The pump can also be
switched on/off in "mode A" with button (3). The
dry run protection operates in the same way as in
normal mode.
