2. Installation and operation
2.3 Commissioning
1. Check the leak tightness of the system
2. Flush, fill and bleed the pipework (with filling water in accordance with VDI 2035).
3. The freshly filled heating water will naturally outgas when the boiler is heated. For this automatic deaeration to occur, the automatic air
vent on the boiler guard must not be closed. This deaeration causes the system pressure to drop so that the heating water must be
replenished after the first couple of hours of operation.
4. With new installations in particular, there will be many foreign parts (sealing material, dirt, welding residues) in the system, which will
accumulate in the boiler guard. The first maintenance check should be performed after a few hours of operation following commissioning.
2.4 Operation
Please note the application limits:
• Permissible media: Heating water (in accordance with VDI 2035, non-corrosive), max. glycol content: 50%
• Permissible pressure rating: PN6 (for special boiler guards PN10 is available)
• Permissible temperature: 0-110°C
• Recommended max. flow rate (if the flow rate is too great, the separation rate will drop)
