3. Positioning and installation
THE APPLIANCE MUST BE CONSIDERED AND HANDLED AS FRAGILE MATERIAL.
THE CIRCUIT DOWNSTREAM OF THE UNIT MUST BE CONSTRUCTED IN PLASTIC AND
STAINLESS STEEL TO PREVENT CORROSION.
IF THE WATER SUPPLY CONTAINS PARTICLES IN SUSPENSION, AN EXTERNAL FILTER
MUST BE INSTALLED TO PROVIDE SUFFICIENT DOWNSTREAM FLOW AND PRESSURE ;
THIS FILTER MUST BE KEPT IN PERFECT CONDITION AT ALL TIMES .
Positioning:
Before installing the appliance, check that there is sufficient clearance for easy extraction of consumables and for servicing the unit. Check that there is a power socket in the vicinity of the unit. The appliance is designed for installation in clean area, protected from freezing temperatures.
Before installation, check:
- that there is sufficient space for the plumbing
- that there is good access for equipment, inspections and maintenance
Electrical hookup:
Make sure the power supply is adequate to the unit’s draw.
Caution: the power voltage rating is given on the unit’s dataplate.
WARNING: Do not open the unit’s electrical panel ; only qualified persons may do this.
Plumbing hookup:
Hook the machine up as indicated on the unit itself, “IN” indicates the water supply inlet, “OUT” indicates the osmosi-treated water outlet, RJ indicates the discharge outlet. Remove the red cap “T” from the RJ fitting and insert the water drain pipe supplied with the unit.
Apply the supplied pipe to the OUT fitting and equip its free end with a corrosion-proof cock if it is not hooked up directly to the service.
The water supply pressure may not exceed 6 bar nor be less than 1.5 bar.
WHEN FIRST RUNNING THE UNIT AND AFTER ANY SERVICE, RUN THE WATER DELIVERY
TO A DRAIN FOR AT LEAST 20 MINUTES SO AS TO ELIMINATE ANY IMPURITIES
RESULTING FROM THE WORK JUST DONE
All quick fittings are of the type

Pressurizing and starting up the unit:
After all pipes have been connected, pressurise the system gradually and check for leaks.
Turn the “Osmosis pump” switch to “I”. Check that the following message displays:
In normal operation the value Rj varies during osmosis-treated water production.
Wait 5-10 minutes, then continue by starting up the delivery pump.
I M P O R T A N T !!!
Delivery pump startup (first startup)
Remove the red bleeder cap P (“Sfiato innesco”) on the front (close to the pressure gauge, labelled as such) .
To remove the cap, press the John Guest clip and allow a bit of water to run into a container; refit the cap P, and actuate the “Delivery pump” switch.
FAILURE TO FOLLOW THIS PROCEDURE TO

DAMAGE TO THE DELIVERY PUMP.

4. Maintenance
The osmosis treatment unit runs completely automatically and maintenance is minimal. The only essential operation is periodic replacement of the filter cartridges.
IMPORTANT
Replace the pre-filter every 3000 hours of operation and AT LEAST 1 time a year.
Pre-filter Membrane
Replacing the pre-filter:
Filter cartridge replacement procedure
- Shut off power;
- Close the side cocks (RL);
- Vent the circuit from the top cap (S);
- Unscrew the filter housing (use the special wrench supplied in the accessories bag). Place a container to drain the water in the filter into;
- Fit the new cartridge and check it is correctly seated;
- Check for leaks and water in the bottom of the appliance;
- Dry it off thoroughly.
Replacing the membranes:
Cartridge replacement procedure.
- Shut off power;
- Disconnect all hoses from the membrane housings, unscrew the base, and place a container to catch the water contained in the cartridges;
- Refit the membrane, check the seating of the o-ring and screw the housing fully in; reconnect the hoses and make sure they are correctly seated;
- Do not apply excessive force;
- Fit the new cartridge and check it is correctly seated;
- Start the unit up and check for leaks.
Special adjustments:
RECIRCULATION
Recirculation retreats the waste water to reduce the amount of water rejected. Turn the needle valve “Recirculation” to retreat the waste water, thus reducing overall water consumption.
Important!
Make sure, when making adjustments, that the pressure gauge reading never exceeds 10-11 bar.
BYPASS
Turn the “Bypass” needle valve to adjust the conductivity of the osmosis-treated water, at the expense of the hourly water production and the amount of water rejected.
NOTE:
In both cases, before setting the needle valves you must slacken off their collars and tighten them down after the adjustment has been made.
Recirculation Bypass
Collar
Inactivity:
There are no special warnings regarding maintaining the appliance’s operability when kept inactive for short periods of time.
For long periods of inactivity contact your local Authorised Reseller so that he can remove and store the inverse osmosis membranes and also restart the unit after recommissioning as for the first installation.

In stand by: hold down UP/DOWN together to enter programming mode:
(in all the following procedures: UP/DOWN changes the value, ENTER saves and continues, F1 continues without saving).
Programming procedures: >>>>>>>>>>>>>>>>>>>>>>>>
X.X indicates the software version (e.g. 2.1)
Display: Program filtration hours
Press ENTER or F1:
Flussaggio auto (auto flush):
This is an auto flush cycle run by the system to prevent stagnation in the circuit. After the set number of hours, the solenoid valves open to flush/refresh the water in the circuit.
Press ENTER or F1:
Stop motore se in moto per … (Stop motor after …)
The following two messages concern the osmosis pump motor condition. Set = 0 to exclude this mode; if the value is not 0, the motor stops running after having run continuously for the set period, then starts again.
After two seconds, the system displays:>>>>>>>>>>>>>>
Press ENTER or F1:
If the conductivity value remains below set value, no alarm trips, otherwise an alarm displays.>>>>>>>>>>>>>>>>>>>
Press ENTER or F1:
Set number of pulses per litre for the product flow meter.>>>>>>>>>>>>>>>>>>>>>>>>>>
Press ENTER or F1:
Set number of pulses per litre for the waste flow meter.>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Press ENTER or F1:
Set minimum production below which a fault is reported.>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Press ENTER or F1; the system returns to standby.
The switch at the top of the display, if pressed to the right, switches from the waste water flow display to the osmosis-treated water flow display. When it is released, the display returns to waste water flow mode.
