2. INSTALLATION

 In case of hard water (with high lime-scale content = hardness in French degrees higher

than 25 – 30, or 250 ÷ 300ppm) it is necessary to employ an ion exchange water softener.
This unit must be calibrated so as to maintain a residual hardness rangin g between 5 and 10
French degrees (50 ÷ 100ppm). The use of electronic water softeners is not advised, since
their efficacy has not been proved yet.

 Fix the doser-mixer on the wall at a height from the floor of 1350 ÷ 1550mm, usi ng the four

wall plugs supplied. The90° wall plug hook is supplied to provide support for the water
delivery outlet elbow.

Do not place other machines below the DOSER – MIXER.

 Arrange the water inlet tubing as shown in the lay-out diagrams, figures 2 – 3 – 4 – 5,

mounting the ball gate valves (1) at the end of the pipes (black lever = cold on the right
and red lever = warm on the left).

 With reference to the figure 4, it is advisable to use the pre-assembled group: Three way

connection kit, code 3801205.

 With reference to the fig. 5, the use of Automatic kit is foreseen, code 3801231 (230V).
 Connect ball gate valves to the doser-mixer by means of the "O" ring gasket type unions (2).
 Insert the delivery hose (12) into its housing.
 Connect the by-pass (13) to a drain by means of a copper pipe with 16mm external

diameter.

 Connect to the proper power supply (see equipment rating plate near the plug 7),

monophase 50 or 60Hz, using the supplied flying socket, fitted with a three core cable min.
section 3x1mm². An external switch is helpful.

 For the eventual pump remote control, use the supplied flying socket to connect the

remote control switch of the pump(s). The use of such a pump is necessary when one of the
two inlet pressures is less than 1 bar, for example when usi ng unpressurized water heaters or
refrigerators.
The plug on the device has the following wiring diagram (clean contact):
