DOMIX 35 – Rev.7 - 02.09.2014 12/30
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.
2 fuses, for the pump and logic board, are also fitted on the logic board and can
also be replaced when needed only by qualified personnel.
The installation must be carried out by skilled personnel under the supervision of a qualified
person. All electrical connections must comply with the local requirements at the place of
installation. The machine must be earthed and protected against short circuits and
overloads.
In case of 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 softener.
This unit must be calibrated so as to maintain a residual hardness ranging between 5 and
10 French degrees (50 ÷ 100 ppm). The use of electronic water softeners is not advised,
since their efficacy has not been proved yet.
Fix the doser mixer to the wall at 1350 ÷ 1550 mm height from the floor, using the two wall
plugs supplied. The 90° wall plug hook is supplied to provide support for the water delivery
outlet elbow.
Do not place other machines below the device.
Arrange the water inlet tubings, mounting the ball taps (1) at their ends.
Provide to insulate thermically the inlet pipes to obtain the best performances.
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.
Perform a purge of all pipes to eliminate waste processing, which could damage the
equipment.
Connect the doser to the ball taps using connectors (2).
Connect the delivery tube (10) to the machine.

Manual Code 2600103
DOMIX 35 – Rev.7 - 02.09.2014 13/30
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
connections and safety regulations.
Connect to the proper power supply using the supplied flying socket, fitted with a three
core cable min. section 3x1,5mm². 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 in less than 1 bar, for example when using unpressurized water
heaters or refrigerators.
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 Domix, through a
power relay.
The pump command plug on the device has the following 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 figure.

DOMIX 35 – Rev.7 - 02.09.2014 14/30
- UNIT OPERATION
Switch on the doser mixer using the external switch (or by plugging in the flying socket).
The first displays appearing at the switching on refer to the self test. The displays show the
model and the microprocessor software version.
At the end of the self test the display show:
−he quantity of the last discharge.
−Internal temperature.
Set desired water quantity using [+] and [-] keys. Setting appears on display (13).
Increases/decreases may be obtained in three different ways:
step by step: pressing once [+] and [-] keys
continuous: keeping constant pressure on [+] and [-] keys
fast: 3 seconds after keeping constant pressure on [+] and [-] keys.
Press [START] key to execute the batch.
Water delivery may be stopped at any time by pressing [STOP/C] key. Quantity of water
delivered will then flash on display (13).
To resume delivery of remaining water press [START] key.
Press [STOP/C] key and the original litre setting will reappears on display. Press [STOP/C] key
again to clear memory.
Quantity in memory is retained at the end of each dosing. Simply press [START] key if
identical successive dosing is desired. Memory is protected against power failure; pre set
dosing can be resumed pressing [START] key when power is restored. In this case the
display shows the message “TensFAI”. At the first pressure of the [STOP/C] key the machine
shows the discharged quantity till it was stopped, the operator may now cancel the
discharge by pressing again the [STOP/C] key, or to resume by pressing [START].
Water temperature is selected by turning the temperature regulation knob: the
temperature is shown on the electronic thermometer display. When regulating the water
temperature wait a few seconds between adjustments so as to allow the temperature to
stabilize.
To ensure optimum operation the warm water temperature must be at least 10° C higher
than the required delivery water temperature and the cold water should be at least 5°C
lower.
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.
Low temperatures (below 10 ÷ 15°C) may be obtained only when using a refrigerator.
The scales have been obtained with temperatures of 3° C (refrigerated), 18° C (net) and
65° C (warm).
7.1. Free batch special function
It is possible to perform a special recipe controlling only the temperature (press [STOP] and
[-] together to enter).
On the left display appears [FrEE], the right display shows the water temperature.
With the [START] and [STOP/C] keys the solenoid valve opens and closes.
To exit, press [STOP] and [-] together.
This function may be useful also in case of a liter counter failure.

8- ERRORS
All error messages are shown by flashing messages and an intermittent led signalling in the
litres display. The last one can be stopped with the [STOP/C] key. Using the [START] key the
error message is cancelled and the delivery starts again. On the contrary, the double
[STOP/C] command cancels the delivery. The possible error messages are listed here
below.
8.1. Litres-counter error
