4 Commissioning
1. Check the leak tightness of the system
2. Flush, fill and bleed the pipework
Warning!
Once the boiler or tank has been filled and has undergone a pressure and leak-tightness test,
the heating/cooling circuit may only be operated by opening the ball valve in the supply
line, because the overpressure (test pressure) in the boiler/tank could damage the backflow
preventer in the backflow ball valve.
3. Select the appropriate recirculation pump setting
4. Check the functions
5 Maintenance
We recommend performing regular leak-tightness tests.
Bimetallic thermometer
The thermometers are simply inserted and can
be removed easily. It should be ensured that any
thermometer that is removed is replaced with
a similar one. Please observe the colour coding.
(Red lettering = FL;
The thermometers are in measurement accuracy class 2 in
accordance with DIN EN 13190. The display can be adjusted
by rotating the groove on the measurement element.
The ball valve handle pieces are torsion-resistant and can only be reinstalled in one direction.
The position of the ball valve, i.e. open or closed, can be identified from the position of the
handle piece.
Pumps
Pumps can be exchanged without having to drain the entire heating/cooling system. Close the
pump ball valve and mixer. In the case of the mixer, the bypass must be closed and the shaft
rotated so that the flat face points in the direction of the closed side.
Note
When changing the pumps in an MC group, some of the system water may leak out through the
mixer. Any drops can be caught by an absorbent cloth or in a bucket.
In the UC version there is an additional shut-off ball valve below the pump.
