Flange valves on mix-block
Figure M 19. The mix-block is removed from the machine for clarity. Shown here are brass flange
valves, these can be exchanged with stainless steel flange valves although these need other screws
(6mm thread). The cold water valve is already removed from the mix-block to show bottom of flange.
Note the position of the off-centre hole in the dismounted cold water valve (off-centre hole in the hot
water valve is to the left) and make sure that the two Viton O-rings are in place before (re-) mounting.
Electric pins on coils are covered with protective cap.
1. Remove electrical plug from coil.
2. Remove flat nut retaining coil to valve with spanner 14 mm, remove coil.
3. Remove 4 screws that hold the flange valves to the mix-block with Phillips screw driver no. 2.
4. Replace flange valve. When mounting, make sure that the new valve has both Viton sealing O-
rings and that you position the openings in the flange over the openings in the manifold (see
Figure M 19). Use new locking washers (M4) on flange screws.
5. (While at it, check the 0.7 mm restrictor underneath the cold water valve.)
6. Mount new coil with correct side up and electrical connectors in the proper position. When
mounting, tighten the flat nut on top just enough to flatten spring nut. Too much strain on the coil-
tube will separate it from the valve.
7. Mount electrical plug on coil with rubber seal and screw.
