2. CHARACTERISTICS OF THE DEVICE
2.1. RECOMMENDED USE
OSMO-MAXI is equipment designed for dish/glass wash machine water treatment. It is able to modify
organoleptic and chemical characteristics of potable water, reducing saline content, for supplying water
with a low salt content to dishwashers and glass washers equipped with an atmospheric pressure boiler. In
case of use with a dishwasher with pressure boiler, it is necessary to provide, between the machine and
the dishwasher, an expansion vessel of at least 18litres, with a preload of approximately 2.5bar.
ATTENZIONE
OSMO-MAXI is not a water purifier. Using OSMO-MAXI to condition water that is not
drinkable is ABSOLUTELY PROHIBITED.
You cannot treat waste water, seawater or other water in chemical, physical and
bacteriological conditions that aren't in the practical possibilities of reverse osmosis
treatment (industrial or chemical processing waste water).
The device is not intended to be used by people (including children) whose physical,
sensory or mental abilities are reduced, or lack of experience or knowledge, without
supervision of a person responsible for their safety. Children should be supervised to
ensure they do not play with the appliance.
2.2 DESCRIPTION
The machine has on the rear three hydraulic connections, respectively, for the inlet water to be treated,
the permeate output and the concentrate output, there is also a power supply cable and a manual by-pass
valve. On the front side there is an electronic control board with display. Before water entering, you must
install an external carbon block pre-filter Profine® BLUE small.
The manual by-pass valve allows, in case of malfunctions, to exclude the osmosis system, supplying raw
water to the dishwasher downstream. The device has a conductivity probe for measuring the water
quality.
For the control of start / stop, the machine is equipped with a high pressure switch on the permeate.

5 FUNCTIONING
5.1 NORMAL USE
WARNING

The first start of the device must be performed by the installer that checks its proper
operation.
For normal use of the equipment you need to keep it always on, with by-pass valve in the rear in "OPEN"
position.
The machine starts up automatically at every dishwasher rinsing, controlled by the inner maximum
pressure switch.
WARNING

Avoid absolutely membrane dehydration, because this would irreparably compromise the
operation.

The equipment does not require continuous monitoring, but check every day the
conductivity and the remaining hours to filter changing (see § 5.9).
WARNING
!
At the end of the day, close the inlet water valve and disconnect the power plug.
5.1.1 Automatic Flushing
In order to reduce bacteria proliferation on the membrane surface, the machine automatically performs
the " flushing" every 6 hours. This operation consists in opening the inlet solenoid valve for two minutes,
discharging stagnant water in the membranes.
It’s possible to start the flushing from menu manually (see § 5.9).
5.2 USE OF REAR BY-PASS VALVE
The equipment is supplied on the rear with a manual by-pass valve that allows you
to exclude osmosis system and provides raw water downstream in case of
malfunction.
The valve can be rotated into position:
-OPEN ( ) open osmosis system
-CLOSE ( ) water closing position
-BY-PASS ( ) by-pass position.
WARNING

When the valve is in CLOSE or in BY- PASS position, unplug
the power supply.

5.3 BEHAVIOR IN THE EVENT OF FAILURE
WARNING
!
In the event of water leak, disconnect the power plug and close the inlet water valve,
then contact the service centre.
!
In case of electrical or mechanical failure that causes failed starting of the equipment
or insufficient production of water, turn the valve back to " BY-PASS" and disconnect
the power plug.

5.4 INACTIVITY
WARNING
!
At the end of the day, close the inlet water valve and disconnect the power plug.

If the machine remains idle for a period longer than a week, fill and empty the washing
tank.

Perform the sanitation of the equipment during extraordinary maintenance operations, or
in the event of inactivity longer than a month.

If extended inactivity (more than one month), and/or storage at temperatures below 0 °
C will be considered, contact assistance service to perform the procedure of flushing with
antibacterial solution with antifreeze.
5.5 HIGH CONDUCTIVITY ALARM
If after 50 seconds, from the start, the conductivity of the water produced is
higher than 70 µS/cm, the display will show "Hi cond. Alarm" Check the
conductivity of the water produced by pressing the key when the machine is in
operation. If it’s continually higher than 70 µS/cm with inlet water < 1.200 µS/cm,
contact the assistance service to change the membranes. The high conductivity
alarm does not block the equipment.
5.6 REPLACEMENT FILTERS ALARM
Change the filter after 140 hours of operation. After replacement, reset the time
(see § 5.9). Filter replacement alarm does not cause the blocking of the
equipment.
5.7 MINIMUM PRESSURE ALARM
In case of insufficient inlet pressure, the equipment stops and gives three BEEPs
off, displaying the alarm on the display. The low pressure switch is ignored for 20
seconds from the start.
After a minute, the equipment will automatically turn on. In the case of
consecutive pressure alarms, the delay of automatic restart automatically
increases.
5.8 LEAKAGE ALARM
The machine has two leakage probes inside. When the water makes the probes
wet, the board gives a long BEEP off and stops, displaying the alarm.
WARNING
!
In the event of a water leakage, disconnect the power plug and close the inlet water
valve, then contact the service centre.
In case of high environmental humidity, it is possible that leakage alarm intervenes even
in the absence of water leakage.

In this case, unplug, keep the key down and connect the plug.
The board performs three BEEPs and resets the alarm.
If the alarm is repeated, contact the service centre.
