6 Description of the Pump
In an average household, around 10 to 20% of the energy consumpti-
on is caused by common standard pumps. The TacoFlow2 PURE PLUS
pump can reduce energy consumption by up to 80% compared to
a standard circulation pump, whilst maintaining the same level of
hydraulic power.

8 Installation
The circulating pump is installed in the pipeline and as a rule,
directly upstream of the service water reservoir in such a way that
the water from the last tap is pumped back to the reservoir through
the circulating pipeline. A check valve must be installed on the
pump’s discharge side (primary side) to prevent pump backflow
when the tap is opened. Assemble the pump with the horizontally
positioned pump motor when the power is shut off (the arrow on the
pump housing shows the direction of flow). Ensure when performing
the heat insulation work that the pump motor and the electronic
housing are not insulated.
Install the device with the power supply disconnected and with
the pump motor lying horizontally (the arrow on the pump housing
shows the direction of flow) (Fig. 1).
When performing insulation work, ensure that the pump motor and
the electronics housing are not covered in insulation.
Observe the permissible
mounting positions:

9 Electrical connection
Warning: Risk of death!
Improper installation and improper electrical connection
can present a fatal hazard.
Hazards posed by electrical power must be eliminated.
• Only have installation and electrical connection performed by a
specialist and in line with the valid regulations (e.g. IEC, VDE, etc.)!
• The current type and voltage must correspond with the
information on the type plate.
• Observe the specifications of local energy supplier!
• Observe accident prevention regulations!
• Never pull on the power cable
• Do not bend the cable
• Do not place any objects on the cable
• When using the pump in systems at temperatures over 90 °C,
use a connection line that is suitably heat resistant.
• Hazards such as sharp edges and burrs arise during installation.
• When transporting the pump, never hold it by the power cable.
• The pump could cause an injury if it falls.

Note
10 Filling and Venting the System
The system must be thoroughly flushed
before the pump is started up to prevent
contaminants or foreign bodies from
remaining in the system.
Fill and vent the system correctly.
Incomplete venting can lead to noises
in the pump and system.
Warning! Risk of burns!
The entire pump can be very hot,
depending on the operating state
of the system.
Tighten the union nut with 30 Nm
torque. Use filter wrench.
11 Service and Maintenance
The pump is nearly free of maintenance. If the pump was not wor-
king for a longer time or the system is heavily contaminated could
the rotor be blocked. It will shown by flashing of the upper LED light.
By removing of he motor head ( loosening the union nut and remove
the motor head ) the impeller is accessible and can be also remo-
ved. By doing this the blockade can be solved and / or the pump can
be cleaned. Tighten the union nut with 30 Nm torque.
Switch off the power to the system before performing maintenance,
cleaning or repair work, and secure it against unauthorised reacti-
vation.Allow the pump to cool down in the event of high temperatu-
res and system pressures.
There is a risk of scalds!
