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 ranging 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, using 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 using unpressurized water heaters or refrigerators.

The plug on the device has the following wiring diagram (clean contact):
