Warning
- Respect the working parameters shown in the label affixed to the filter housing.
- If pressure exceeds the working conditions, protect the product with a pressure reducer.
- Protect from excessive cold or heat: do not expose to temperature below 39°F (4°C)
or above 113°F (45°C).
- Protect from back-flows of hot water with a non-return valve.
- Protect from hammering with an anti-hammering device. In case of installation on
systems powered by a pump and especially on those equipped with a pressure and
flow controller, an additional expansion vessel must be installed upstream the filter
to protect it from possible repeated pressure peaks.
- Should the filter (h cartridge) be left not in use for more than 1 week replace
cartridge/s with new one/s prior to use.
Operations for the replacement of a filter cartridge
See figures and follow step-by-step instructions below to replace a filter cartridge.

The values of the maximum working temperature and the maximum
working pressure shown in the label affixed to the filter housing are
intended as maximum working parameters and must not be exceeded. Use
of the filter under higher pressure conditions could cause ruptures.
