If the mixer flow rate decreases, carry out the following; turn off the main water sup-
ply and using a 14mm hexagonal wrench remove the screws -20- from the bottom of
the mixer. Pull and remove the mixer from its seat. Using a 15mm wremch, tighten the
s-connector 49 enough to lock it in position; using a 30mm wrench, unscrew the filter
seat 47. Slide off the filters 48 (fig.A) and clean them. Reassemble by following the
instructions in reverse order, making sure the s-connector 49 doesn’t move while
reassembling the seat 47.
If there’s a difference between the temperature of the indicator and the mixer’s, carry
out the following: turn off the main water supply, remove the handle cap -1- loosen the
screw -2- slide off the handle -3- and the temperature blocking system -8- unscrew
the lock nut -9- using a 34mm wrench, remove the cartridge -10- insert the new car-
tridge pressing firmly -10- and apply a thin layer of lubricating grease on the o-rings.
To reassemble, proceed in reverse order making sure index -D- is aligned with point
-C- tighten the cartridge with lock nut -9-. Now, adjust the temperature and complete
the assembly by carrying out the same procedures in reverse order. The indicator -E-
of the temperature blocking system -8- must be aligned with point -C-.
Remove the handle cap -1- loosen the screw -2- slide off the handle -16- loosen the
lock nut -15- using a 27mm wrench, remove the cartridge -14- and insert the new car-
