2. Installation

Flush the installation thoroughly installing the FlexBalance (Plus).
Install the FlexBalance (Plus) in a dry location not suscreptible to frost and which is easily
accessible for maintenance purposes.
The FlexBalance (Plus) should be connected vertically to the fl ow and return circuit as close to the
boiler as possible (fi g. 1).
Note: the sensor connection must be located at the outlet side to the installation (the second
circuit) (fi g. 1).
For maximum effi ciency the fl ow rate in the fl ow pipe should be approx. 1 m/s (maximum 2 m/s).
The valve end of the air vent has an external measurement of 22 mm allowing it to be easily
attached to the air venting pipe which should slope downwards (fi g. 2).
For ease of maintenance there must be a clearance (fi g. 3) of at least 100 mm above the air vent.
Before using the temperature sensor, remove the plug from the sensor connection and install an
immersion pipe with a G½" connection. See the table for the correct immersion pipe length (X)
(fi g. 5, 6).

3. Inspection and maintenance

Perform regular inspections.
To remove the silt that collects inside the FlexBalance Plus use the drain tap
(only for FlexBalance Plus).
To fl ush the FlexBalance (Plus) properly it is recommended to place the product between stop
valves. In the unlikely event of contamination or leakage from the air vent this valve can be closed
by turning the integrated screw (fi g. 4).
