Cleaning

Inspection and Maintenance

The boilers can be cleaned with a commercially available
domestic cleaning agent (non-scouring).
Clean the surface of the operating unit with a microfiber
cloth.
Regular maintenance ensures trouble-free, energy
efficient, environmentally responsible and safe heating.
Your heating system must be serviced by an authorised
contractor at least every 2 years. For this, it is best to
arrange an inspection and maintenance contract with
your local heating contractor.
Boiler
Increased contamination raises the flue gas temperature
and thereby increases energy losses. We recommend
the boiler be cleaned annually.
DHW tank
Maintenance or cleaning should be carried out no later
than 2 years after commissioning and thereafter as
required.
Only a qualified contractor should clean the inside of
the DHW tank and the DHW connections.
If any water treatment equipment (e.g. a sluice or
injection system) is installed in the cold water supply
of the DHW tank, ensure this is refilled in good time.
For this, observe the manufacturer's instructions.
Safety valve (DHW tank)
The function of the safety valve must be checked
every six months by the user or a contractor through
venting (see valve manufacturer's instructions).
The valve seat may become soiled.
Water may drip from the safety valve during a heat-up
process. The outlet is open to the atmosphere.
CAUTION
Overpressure can cause damage.
Do not close the safety valve.
Potable water filter (if installed)
To maintain high hygienic standards, proceed as follows:
Replace filter element on non-back flushing filters
every six months (visual inspection every two months).
On back flushing filters, back flush every two months.
