Before connecting the thermal module the protection
plugs must be removed from the delivery, return and
condensate drain pipes.

Before connecting the thermal module, it is neces-
sary to clean the system. This step is absolutely re-
quired when the appliance replaces another one on
pre-existing systems.
In order to carry out this cleaning activity, if the old genera-
tor is still installed on the system, it is advisable to:
- add a de-scaling additive.
- Operate the system with the generator on for around
7 days.
- Discharge dirty system water and flush the system
one or more times with clean water.

If the system is very dirty, repeat the last procedure one
more time.
If the old generator is not present or available, use a pump
to circulate the water + additive through the system for
about 10 days and perform a final washing as described in
the previous paragraph.
Once the cleaning has been completed, it is recommend-
ed to add a suitable protective fluid to the system's water
before installing the thermal module.
In order to clean the heat exchanger's built-in water sys-
tem, please contact Technical Assistance Centre
a
Do not use incompatible liquid detergents, including
acids (for instance, chloridric acid and similar) in any
concentration.
a
Do not subject the heat exchanger to cyclical pres-
sure changes because fatigue stress is very danger-
ous for the integrity of system components.
