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.

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.

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 .

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

THE LETTER CAN CAUSE SERIOUS
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.

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;

- Close vent S and open the side cocks RL;

- Check for leaks and water in the bottom of the appliance;

- Dry it off thoroughly.

Pre-filter Membrane

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.

- 36 -

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
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.
