Maintenance
Caution
The quality of the circuit water must be checked and documented
as part of annual system maintenance. Depending on the
measurement result, the necessary measures must be taken in
order to re-establish the required values for the circuit water.
Furthermore, the cause of the changes must be established and
permanently corrected in the event of severe deviations. Warranty
claims are excluded if the specified values are not adhered to or if
documentation is missing.

The total water volume in the heating system is calculated using the
system volume (= fill water volume) plus the top-up water volume. In the
Potterton Commercial boiler-specific diagrams only the system volume is
given to make them easier to read. Over the entire service life of the
boiler, a maximum top-up volume of twice the system volume is assumed.
5.2.6 Practical information for qualified heating specialists
If an appliance is replaced in an existing system, we recommend
installing a sludge separator, e.g. WAM C SMART (accessory) in the
system return, upstream of the heat generator. Potterton Commercial
recommends using the AguaClean filtration module to achieve an
optimum cleaning result, including magnetite deposits.
Document the filling (VDI directive 2035 Sheet 2 Section 4 "Principles").
The Potterton Commercial service book must be used for this.
To prevent gas pockets and gas bubbles, it is essential to fully vent the
heat generator at maximum operating temperature.
Offer maintenance contracts for all the equipment in the system.
Check proper operation with regard to pressure maintenance on an
annual basis.
Potterton Commercial recommends using of approved systems for initial
filling, for replacing water and for top-ups.
5.2.7 Use of antifreeze agents with Potterton Commercial heat
generators
Important
The use of antifreeze agents with Potterton Commercial gas-fired
condensing boilers with aluminium heat exchangers.
