10.1.3 Lifetime of safety-relevant components
Safety-relevant components (e.g. gas valves) have a limited lifetime that
mainly depends on the operating years and the operating cycles. The
remaining lifetime of individual safety-relevant components can be
determined as part of maintenance work carried out by an approved
installer. If the lifetime Potterton Commercial in accordance with the
following table is exceeded, recommends replacing the relevant
components.

10.1.4 Protection against contact
Danger of electric shock
Danger to life due by missing shock-proof protection.
To ensure shock-proof protection, all parts of the boiler to be
screwed on – the casing parts in particular – must be screwed on
correctly after work has been completed.
10.1.5 Approved detergents
Cleaned heat exchangers improve heat transfer and save energy. The
following detergents have been tested and approved by Potterton
Commercial for cleaning heat exchangers:
Sanit Care aluminium-silicum heat exchanger special cleaner
Sotin 240 boiler cleaner
Danger
Cleaning agents for aluminium heat exchangers are irritants
and/or corrosive.
Before starting work the corresponding security and safety
measures of the manufacturer must be observed. In addition the
instructions for use and transport printed on the packaging and
container must be observed.
See
The Potterton Commercial maintenance instructions must be
observed.
Important
The safety data sheets for the detergents listed are included with
the product or are available from the respective manufacturers.
Caution
During application of the detergent only the heat exchanger on the
flue gas side may be treated. No detergent residue may remain on
the boiler components, the cable plugs or casing, since this can
otherwise lead to corrosion and appliance malfunction. Residues
sprayed by mistake must be cleaned off immediately using a
damp cloth.
