6- INSTALLATION
Fundamental operations relating to lifting, transportation, installation, start-up,
maintenance and repair work must be carried out only by qualified personnel.
Disconnect the electrical power supply when carrying out any of the above.
A further 2 fuses, specifically for the pump and logic board, are also fitted inside the
machine and can also be replaced when needed.
The installation must be carried out by skilled personnel under the supervision o a quali ied
person. All electrical connections must comply with the local requirements at the place o
installation. The machine must be earthed and protected against short circuits and
overloads.
In case o hard water (with high lime scale content = hardness in French degrees higher
than 25 ÷ 30, or 250 ÷ 300 ppm) it is necessary to employ an ion exchange water so tener.
This unit must be calibrated so as to maintain a residual hardness ranging between 5 and
10 French degrees (50 ÷ 100 ppm). The use o electronic water so teners is not advised,
since their e icacy has not been proved yet.
Fix the doser-mixer on the wall at a height rom the loor o 1350 ÷ 1550 mm, using the our
wall plugs supplied. The 90° wall plug hook is supplied to provide support or the water
delivery outlet elbow.
Do not place other machines below the device.
Arrange the water inlet tubing as shown in the lay-out diagrams, Fig. 2, mounting the ball
taps (1) at the end o the pipes (black lever = cold on the right and red lever = warm on
the le t). Provide to insulate thermically the inlet pipes to obtain the best per ormances.
It is recommended to perform links as short as possible from the chiller / boiler to the
DOMIX, avoiding going through the pipes near sources of heat such as the ovens.
Per orm a purge o all pipes to eliminate waste processing, which could damage the
equipment.
Connect the ball taps to the doser-mixer by means o the "O" ring gasket type unions (2).
Insert the delivery hose (13) into its housing.
Connect the by-pass (14) to a drain by means o the supplied tube.
Absolutely forbidden to enter directly into the bypass (14) a fixed pipe to ensure the
possibility of disassembly for maintenance.

Manual Code 2600201
DOMIX45 – Rev.06 - 02.09.2014 13/32
Check that the voltage and frequency correspond to those shown on the unit data
tag. Make sure that the electrical installation complies with the local electrical
connection and safety regulations.
Connect to the proper power supply using the supplied lying socket, itted with a three
core cable min. section 3x1,5mm². An external switch is help ul.
For the eventual pump remote control, use the supplied lying socket to connect the
remote control switch o the pump(s). The use o such a pump is necessary when one o
the two inlet pressures is less than 1 bar, or example when using unpressurized water
heaters or re rigerators.
NOTICE: in the case of water chiller equipped with a surge tank with pressure switch, this
must be by-passed and the pump must be controlled directly by the Doser, through a
power relay.
The pump command plug on the device has the ollowing wiring diagram (clean contact,
digital output, no tension output):
Fig. 5 (pump control wiring diagram)
This is a normally open (NO) clean contact that closes when the unit requires chilled
water. So it doesn’t supply any tension.
It is recommended to use it to cut phases with current not higher than the amperage
indicated in the igure.
The equipment is itted with an auxiliary precision electronic thermometer with a mobile
probe (5), usable at distances up to 5 metres.

thermometer (9). In case o correction, wait a ew seconds be ore intervening, so as to
allow the temperature to stabilize.
To ensure optimum operation the warm water temperature must be at least 18°F higher
than the required delivery water temperature and the cold water should be at least 9°F
lower. Low temperatures (under 50 ÷ 60°F) may be obtained only using a re rigerator.
ATTENTION: the graduated scales are indicative. They suffer from the temperature of the
water input. The scale "red" indicates the temperature of the mixed output when you use
NETWORK+HOT. The scale "blue" indicates the temperature of the mixed output when you
use CHILLED+NETWORK. They have been obtained with temperatures of 3°C (refrigerated),
18°C (net) and 65°C (warm).
To manually stop water delivery at any time press the [STOP/C] key. In the display (8) the
