7.3 Replacing water and air filter/regulator assemblies
CAUTION Ensure that the water and air supply lines are turned off.
a) Decompress the water and air pressures as described in section 7.1 “Decompressing water
and air pressures” on page G-36.
b) Loosen the two screws attaching the magnetic valve assembly to the cuspidor plate and lift off
the magnetic valve/pressure regulator assembly.
c) If necessary for easier access, disconnect the control cable from the main valve you are
working on.
d) Detach the water (N108-DS02) or air (N108-DS01) filter/regulator by unscrewing the two bolts
which hold it in position.
If necessary, detach the water or air filter by unscrewing it from the water or air regulator.
e) Install the new filter/regulator into position in reverse order.
NOTE Be careful not to overtighten the bolts. (Max. Torque 7 Nm)
f) Adjust the pressure regulator as described in section 3.1 “Adjusting internal water & air
pressures” on page F-26:
• water 280 kPa (2.8 bar) (41 psi)
• air 550 kPa (5.5 bar) (80 psi)
g) Apply pressure to test that there are no air or water leaks.
