Safety
2Safety
About these instructions • Read through these instructions completely before attempt-
ing installation. Non-observance of the safety instructions
can result in risk of injury to persons and damage to pump/
unit.
• When the installation work is complete, pass on the instruc-
tions to the end user.
• Keep the instructions near the pump. They can be used as a
reference if problems occur later.
• We accept no liability for damage resulting from failure to
follow these instructions.
Safety information Important safety information is identified in the instructions as
follows:
Qualification The pump must only be installed by qualified personnel. The
power may only be connected by qualified personnel.
Regulations The current version of the following regulations must be
observed when installing the equipment:
• Accident prevention regulations
• DVGW worksheet W551 (in Germany)
• VDE 0370/Part 1
• Other local regulations (e.g. IEC, VDE, etc.)
Conversion, spares The pump must not be technically modified or converted. Only
use original spares.
Transport Unpack and check the pump and all accessories upon receipt.
Report any damage that has occurred in transit immediately.
Despatch the pump in the original packing only.
Danger: Indicates a danger to life due to electrical voltage.
Warning: Indicates possible danger to life or risk of injury.
Caution: Indicates possible risks to the pump or other
items.
Note: Highlights tips and information.

Technical data
Electricity There is a danger of an electric shock when dealing with
electricity. Therefore,
• switch off the power before working on the pump and make
sure that it cannot be switched on again accidentally.
• Do not kink or nip the power cable or let it come into contact
with heat sources.
• The pump must be protected against drips with IP 42 protec-
tion. Protect the pump against water spray. Do not immerse in
water or other fluids.

4.1 Application
This circulator is suitable for drinking water only.
4.2 Functions
Timer function Up to 3 switch-on/switch-off times can be programmed with the
timer function.
Works setting: 24 hours continuous operation
Temperature control system The temperature control system keeps the water in the return
circuit at the set temperature. To achieve this, the pump is
switched on and off automatically.
This function ensures that
• from a set temperature of more than 55 °C, the danger of
germs forming in the circulation system is reduced
(DVGW requirement),
• lime deposits are reduced,
• the power consumption is reduced.
Works setting: temperature control system switched off.
Thermal disinfection The boiler heats up periodically to approximately 70 °C for ther-
mal disinfection purposes. If the thermal disinfection function is
activated, the pump recognises this from an increase in temper-
ature to more than 68 °C. Irrespective of the timer function, it
then runs continuously for approximately 2 hours and then
switches off again.

Note: The timer function and temperature control system
can be operated together. The timer takes priority. If both func-
tions are activated, there is no temperature control during the
switch-off period.

How it works
Works setting: Thermal disinfection switched off.
Protection in the event of
power failure
If there is a power failure, the pump settings will be retained for
up to 3 hours.
When first installed, this is only guaranteed after an operating
time of 24 hours.
Valves The pump is equipped with a non-return valve (1) on the dis-
charge side and with a stop valve (2) on the intake side.
To replace the motor head (3), simply close the stop valve at the
rotating slot (4). The motor head can then simply be unscrewed
Page 10.
Blocking protection If the pump is switched off via the timer function, it switches on
automatically for 10 seconds every 60 minutes. This automatic
function cannot be switched on or off.
4.3 The menu
The red button All menu settings are made using the red button:
Note: A learning phase starts after the thermal disinfection
function is activated.
In this case, the pump switches itself on for 10 minutes every
20 minutes. If the temperature increases, the time is stored and
the pump continues running until the next increase in tempera-
ture. The interval between these two temperature increases is
stored as the frequency for the thermal disinfection process.
Changes in the times are recognised automatically.

Installation
1. Prepare the installation site so that the pump can be installed
without being exposed to mechanical stresses.
2. Choose the right installation position - only as illustrated in
(Fig. A).
The arrow on the back of the housing indicates the direction
of flow.
Turn the motor head or
remove it.
3. Undo the cap nut - unscrew it completely if necessary.
4. Turn the motor head so that the cable screw connection
points downwards.
5. Tighten the cap nut again.
Open the stop valve 6. Turn the slot (1) with a screwdriver so that it is parallel to the
direction of flow.
7. Fit the thermal insulation shell.
Connect 8. Connect the pipework.
Note: The stop valve and non-return valve are already
installed. No other stop valves are necessary.
A
B
Caution: Do not damage the housing and seal. Replace
damaged seal.
Caution: If the cable screw connection is in the wrong
position, water can penetrate into the pump and destroy the
motor or the electronics.
1
Note: To close the slot, position it so that it lies across the
direction of flow.
Caution: In the case of the versions with check valve and
non-return valve, these are already pre-assembled with a tight-
ening torque of 15 Nm (hand-tight). If the tightening torque is
too high, this will destroy the valve screw connection and the
O-ring.
When installing the valve, use a wrench to prevent it from turn-
ing!

5.2 Electrical connection
The pump is fitted with a cable and shock-proof power plug so
that it is ready to connect. Proceed as follows if the connecting
cable has to be changed:
1. Install a permanent connecting cable with an o.d. of 5-8 mm,
complete with plug device or all-pole switch (with a contact
opening width of at least 3 mm).
2. Open the terminal box.
3. Guide the connecting cable through the cable connection and
strip approximately 5 mm.
4. Secure the cores with the cable clips.
L phase, N neutral conductor, earth
5. Firmly tighten the cable connection.
6. Close the terminal box.
7. Set parameters Page 11.
5.3 Filling and ventilation
1. Fill the system.
2. The pump vents automatically. Thepumpwill not be damaged
if it runs dry briefly.

6.1 To set the current time
Danger: Only a qualified electrician may work on the elec-
trical connection. Before connecting, make sure that the con-
necting cable is dead.
Note: So that the pump functions can be fully used, the
pump needs a permanent power supply. Do not connect the
pump to a boiler control system.
