SAFETY
4.1
INTENDED USE
Both installation and use of the heating circuit filling station are subject to the applicable national regula-
tions. Alongside the operating instructions and the legal regulations applicable in the country and place of
use in respect of accident prevention, the recognised technical regulations for safe and professional work
must be observed.
The heating circuit filling station is suitable for use in cold drinking water up to a maximum ambient tem-
perature of 30 °C. The manufacturer/supplier must be consulted before using water of a different quality
or water with additional additives!
The heating circuit filling station is manufactured according to the state of the art and recognised German
safety regulations.
The heating circuit filling station may only be used as described in the operating instructions. Any other use
or use beyond the specified use is considered to represent incorrect use.
Additional dangers exist in the event of incorrect use and if the danger symbols and safety instructions are
ignored. The manufacturer/supplier shall not be responsible for any resulting damage. All risks are borne
solely by the user.
Intended use includes observance of the operating instructions.
The manufacturer/supplier must be consulted before using the heating filling block outside the limits of
use described in these operating instructions. The heating circuit filling station must only be used as in-
tended in a technically fault-free state, while maintaining safety and hazard awareness, and in compliance
with the operating instructions.
The specifications of the boiler manufacturer regarding the quality of the heating water must be observed.
Ensure that malfunctions are rectified immediately!
4.2
WATER PRESSURE AND BACKFLOW PREVENTER
The water pressure must be between 0 bar and 6 bar.
Where the water pressure is greater than 6 bar, a pressure reducer must be in-
stalled upstream of the heating circuit filling station. If the operating pressure is
greater than 6 bar, malfunctions can occur.
To prevent the heating water from returning to the drinking water supply in ac-
cordance with DIN EN 1717, a Type BA system separator must be installed up-
stream of the heating circuit filling station.
