6.1 Setting the 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 protected against weather influences. Protect
against frost - see section 8.3.
For operation in garden ponds
and swimming pools, the device
must be installed in a flood-proof
location and secured against fall-
ing in. Additional statutory require-
ments must be taken into consid-
eration.
6.3 Connecting the 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! A check valve is absolutely neces-
sary 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 (12)
of the pump. Depending on the model, a check
valve may already be integrated (see section 13.
Technical Specifications).
Seal all screw-couplings 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,
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 the 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 (13) including
gasket.
- Slowly pour in clean water until the pump is filled.
- Screw in water filling screw (13) 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.
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 Explanation of operating elements
Devices with ON/OFF switch (see
illustration A)
Use the switch (1) to turn the device on/off.
Devices with control panel (see illustration B)
For HWA..., HWW...:
Insert mains plug. The pump is ready for operation:
The LED (3) lights up in blue (STANDBY).
Switching on:
To switch on, press the ON/OFF button (4) briefly.
The pump motor starts to run and the LED (3) lights
up in green.
Dry-running protection:
If the pump is unable to convey water after 20
seconds, the LED (3) starts to flash slowly in
green.
If the pump is unable to convey water after a further
100 seconds, the pump motor stops for 5 seconds
(the LED (3) starts to flash quickly in green), and
tries to convey water for a further 2 cycles.
If the pump cannot still convey water, it stops and
the LED (2) lights up in red (dry-running protec-
tion). Check that the end of the suction line is under
water. Check if leaks are causing air intake and
thus preventing water intake. Proceed as
described below to put the pump into operation
once again:
HWA..., HWW...: Press the button (4) and keep it
pressed for 3 seconds (RESET).
P 6000 Inox: Disconnect the mains plug and insert
once again.
When the pump is able to convey water, the LED
(3) lights up in green and remains lit.
Switching off:
To switch off, press the ON/OFF button (4) briefly.
Pump shut-down when the discharge line is
closed:
If the discharge line is closed when the pump is
running, (close water tap or spray nozzle), the
pump must switch off automatically. Otherwise,
overheating or damage can occur or there may be
a risk of scalding due to the heated water. The
electronics check at regular intervals whether
water is flowing through the pump.
HWW..., HWA...: If there is no water flow detected,
the LED (3) flashes in green for 40/70 seconds.
The pump motor then switches off and the LED (3)
lights up in blue (STANDBY).
P 6000 Inox: If there is no water flow detected, the
LED (3) flashes in green slowly for 20 seconds and
then quickly for a further 5 seconds. The pump
motor then switches off and the LED (3) lights up in
red. To put the pump into operation once again:
Disconnect the mains plug and insert once again.
Safety mechanism for insufficient flow volume:
If the flow volume is insufficient (less than approx.
60 l/h, e.g. in the case of leaks), the pump switches
on and off frequently. This can cause the pump to
overheat or get damaged or the heated water may
pose a scalding risk. If the pump tries to switch on/
off more than 6 times in 100 seconds, it is switched
off for safety reasons and the LED (2) lights up in
red. Eliminate the reason for this! To put the pump
into operation once again: Disconnect the mains
plug and insert once again.
7.2 Using the device
Pump
(device designation P...)
Functional principle: The device operates while it
is switched on.
Danger! P 4500 Inox: 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. Fill pump if necessary - see section 6.7.
3. Switch on the device - see section 7.1).
4. Open the discharge line (open water tap or
spray nozzle).
5. Check that water emerges!
6. When work is complete, turn off the device -
see section 7.1.
Only for P 6000 Inox
: A switch to "Mode A" is
necessary if the pump is to be activated via an
attachment unit (e.g. Hydromat (order no.
0903063238), timer). To do this, insert the mains
plug and press the button (4) for more than 3
seconds. The LED (3) changes from green to blue.
The pump can now be unplugged and connected
to the attachment unit.
To return to "normal mode", insert the mains plug
and press the button (4) for more than 3 seconds.
The LED (3) changes from blue to green.
