1GENERAL INFORMATION
1.1 USES
The Pro2 circulating pumps are used for the transfer of liquid medium within systems for hot-water heating,
air-conditioning and ventilation. They are designed as single or twin variable-speed pumping aggregates where
the speed is regulated by electronic device. The pump constantly measures pressure and flow and adjusts the
speed according to the set pump mode.
The pumps have the option of remote control and monitoring using Ethernet, Modbus, analog inputs and
outputs, and relay control. See communication installation for more information.
The main purpose of the twin pump is uninterrupted operation if one of the pumps fails. Common hydraulic
housing is equipped with a change-over flap and two pump heads, separately connected to the electrical grid.

4PUMP INSTALLATION
4.1 INSTALLATION INTO PIPE LINES
Pump is protected with a double box during transport. It can be lifted from the box with internal handles or by
lifting it by the heat sink.
Pumps are designed to be built in connecting flanges, using all screws. The connecting combined flanges are
designed so the pump can be installed in PN6 or PN10 nominal pressure pipelines. Because of the combined
flange design, washers must be used on the pump side, when installing the pump.
For a pump to operate with minimal vibrations and noise it should be installed into pipe lines with its 1-1 axis in
horizontal position, as showed in figure 1. Pipes should be without curves for at least 5-10 D (D = rated pipe
diameter) from the flanges.
Desired head orientation can be achieved by rotating the pump head (allowed positions shown in figure 2 and
3). Pump head is mounted to hydraulic casting with four screws. By unscrewing those, the pump head can then
be turned (figure 4).
Ambient around the pump should be dry and illuminated as appropriate and the pump should not be in direct
contact with any objects. Pump seals prevents dust and particles from entering as prescribed by IP class. Make
sure that the distribution box cover is mounted and that the cable glands are tightened and are sealing.
Pump will provide the longest lifetime with ambient at room temperature and moderate medium temperature.
Prolonged operation at elevated temperatures could increase wear. Aging is accelerated by high power and high
temperatures.
Misconnection or overload could cause pump shutdown or even permanent damage.
Pumps might be heavy. Provide yourself help if needed,
Pump must not be used in the safety pipelines,
Pump should not be used as a holder during welding!
When reassembling, care should be taken to ensure seal fit. Failing that, water could
cause damage to pumps internal parts,
Drains between pump motor housing and hydraulic housing must be left free (should
not be thermally insulated), as it could interfere with cooling and condense drainage,
Hot medium can cause burns! The motor can also reach temperatures that could cause
injury.

4.2 ELECTRICAL INSTALLATION
The pump has a built-in over current fuse and protection, temperature protection and basic overvoltage
protection. It doesn’t need an additional thermal protection switch. Connection leads should be capable of
carrying rated power and should be properly fused. Ground lead connection is essential for safety. It should be
connected first. Grounding is only meant for pump safety. Pipes should be grounded separately.

Connection of the pump must be carried out by qualified personnel,
Connection of the connecting cable must be done in a manner that ensures it is never in
contact with the casing of the device, due to the high temperatures of the casing,
This appliance can be used by children aged from 8 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge if they
have been given supervision or instruction concerning use of the appliance in a safe way
and understand the hazards involved,
Children shall not play with the appliance,
Cleaning and user maintenance shall not be made by children without supervision.
