Accessories

It is a good idea to channel the fluids drained by the safety valves with the

aid of a funnel R141 or R141C (to be ordered separately).

Note.

The use of the R141 relief funnels (plus curved couplings R19 and

R189 if necessary) prevents any spray from reaching the electric

components.

Maintenance

The valve must be checked at least once a year, by increasing the system

pressure to induce drainage. If this is not possible, you can rotate the knob

and check the drainage visually. Any impurities that form on the housing

can be removed by means of regular purging.
