CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
• Wait until hot surfaces have cooled down or wear protective safety gloves.
• The operating authority is required to place appropriate warning signs in the vicinity of the device.
CAUTION
Function restrictions due to magnetic field
The device contains permanent magnets generating a static magnetic field. Magnets can affect the functioning of pacemakers and
implanted defibrillators.
• If you are fitted with such a medical device or other metal implants you must maintain a safe distance relative to the permanent
magnets.
• Provide warnings for people fitted with such devices or metal implants to prevent them from approaching the permanent
magnets.
The time intervals for maintenance work depend on the specific operating conditions.
5.1

Pressure test

• During a hydraulic pressure test, the pressure must not exceed 1½ times the maximum working pressure.
5.2

Cleaning

• The cleaning interval depends on the accumulated dirt within the system.
• The manufacturer recommends an initial check after 4 weeks and at least six-monthly documented maintenance.
• Before commencing cleaning work ensure that the component has cooled and is drained and depressurised.
• Provide a catching container and a pressure and temperature-resistant drain hose, if required.
• After cleaning, use a suitable flange gasket to seal the immersion sleeve.
– Use thread sealant for sizes DN 50 – 100.
• Dependent on the type of medium, ensure any collected dirt content is correctly disposed of.
• Clean the immersion sleeve with magnet insert.
• Check the sacrificial anode.
– If the sacrificial anode is spent by more than ⅔ , it must be replaced with a new anode.
• When filling ensure adequate venting.
• Check the system pressure.
Note!
• Instructions for cleaning the immersion sleeve with magnet insert are located at the end of the complete document.
