Remove the silencer hood.
For inspection and maintenance, it is necessary to remove the silencer hood placed on the storage tank.
Cleaning silencer hood and storage tank
• Clean the easy-to-maintain plastic only with soft cloth and a mild cleaning solution.
• Do not use any cleaners with aggressive solvents, it may damage the plastic surface.
5.2.1 Checking the connections and conduits
• Check all (flue) gas and water-conducting components and connections for leakage and intactness. Have damage corrected
by a specialised agency.
• Check all components of the flue gas system for leakage and damage. Have the damaged parts reconditioned or replaced.
• Check all electrical components, connections and conduits. Have the damaged parts reconditioned or replaced.
5.2.2 Checking and cleaning the condensate drain.
The connection and leakage line of the condensate drain must be free from impurities.
1
Remove the fixing screws.
2
Tilt the silencer hood.
3
Lift the silencer hood off to the front.
Figure 5-1 Remove the silencer hood.
WARNING!
Improperly carried out work on power or gas-conducting components can endanger human life and health and
adversely affect the operation of the GasSolarUnit.
• Only heating engineers authorised and recognised by the gas or energy supply company should replace
damaged power or gas-conducting components in the ROTEX GSU.
• If a Solaris system is connected and is in operation, switch
it off and empty the collectors.
• Open the condensate drain (connection and drain conduit).
• Check that the condensate drain is free from blockages and
clean if necessary.
• Unscrew the overflow hose.
• Visual inspection of container filling level (water level at the
overflow rim).
• Correct the filling level if necessary and determine the
cause for the shortfall in filling level and rectify it.
• Check overflow hose connection and drain section for
leakage, free flow and slope.
Figure 5-2 Check condensate drain
The condensate is a weak acid. It is conducted to the pressureless area of the storage tank. This ensures that,
in normal system operation, the storage tank is always completely full. A long-term neutraliser in the container
ensures that the fluid leaving the container has a neutral pH. Any precipitation remains in the pressureless area
of the container.
