17) INSTALLATION:
- The installation must be done in accordance with current regulations by a qualified person.
- Installation of 2 filter seals at the inlet of the body (provided) mandatory, helping to keep in place, the non-
return valves in the regulator
- This regulator operates in all positions.
- Connect the feeds by respecting the (C-H) and (F-C) markings and the colour bands.
- Adjust the desired temperature as indicated on the views below, verify it at the closest outlet
using a thermometer.
- It is dangerous to supply mixed water over 45° C.
MAINTENANCE:
- For a optimum working, we recommend a regular cleaning (at least every six months) of the moveable shuttle and
the water mixing chamber
- Verify the accuracy of the temperature displayed for a thermostat every year (+/-2° C).
- In case of an abnormally low flow or other, remove the regulator, and clean the inlet filter seals.
- If the problem persists, replace the regulator.
