INTRODUCTION
Osmosis is a natural phenomenon for which a solution poor in mineral salts passes through a semi-permeable membrane then it is diluted
in another one that has a greater saline concentration.
By counter pressure, the process is inverted and is called reverse osmosis: in fact, by pushing a solution with a high concentration of
mineral salts against a special membrane, processed water is obtained.
Due to its structure and properties, the membrane almost completely retains dissolved salts, heavy metals, pollutant elements, bacteria
and viruses letting the water pass in all its genuine purity.
Reverse osmosis is therefore the safest and most widespread purification system around the world; the advantages, other than the basic
reliability of the system, are:
•simple assembly;
•very low operating costs;
•total absence of chemical products.
The Osmo can eliminate from water all impurities and harmful pollutants.
Treated water is the ideal solution for professional use and delivery since the exclusive filtration system forms a safety barrier against
different pollutants in groundwater.
The reverse osmosis purification system Osmo is made with the highest quality components and was designed and configured for professional
use.
All W&H equipment are totally reliable and every component has been designed and manufactured to ensure top performances at all times.
This instruction manual is an essential part of the W&H equipment. It contains important information about installation and operation
security, maintenance and use. This instruction manual should always accompany the W&H equipment, an erroneous installation or use
may cause damage to people, animals or property.
W&H may not be considered responsible for damage caused by improper use, maintenance or installation.
1. General information and Safety advice
5

Note:if the Osmo demineralizer is used to supply sterilizers with demineralized water, it is imperative to monitor the water quality. If the supplied
sterilizers do not feature a water conductivity sensor to monitor the water quality, we recommend using the manual water conductivity
meter Primo 5.
Electrical connection
Before plugging in the unit to the power socket, check that the voltage shown on the rating plate, corresponds to the one of your work
place.
Earthing of the equipment is compulsory by law. Any deliberate cutting of the earth wire inside or outside the unit or removal of
the earth terminal from the plug is forbidden in that the unit becomes hazardous.
The manufacturer declines all responsibility in respect to persons or things arising from failure to observe this rule. The electrical safety of
this unit is only guaranteed when it is correctly connected to an effective earthing system, as provided by current electrical safety laws.
If you do not have an electrical system with proper earthing, do not connect the unit to the socket and consult a specialist electrician as
soon as possible.
General information and Safety advice

This equipment requires earthing.
BEFORE STARTING U THE EQUI MENT
Check that the equipment has not been damaged. Do not use products which have been damaged during transport; if in
doubt consult the retailer or the manufacturer directly.
Use of the Osmo, as with any other equipment connected to an electrical system, involves compliance with certain fundamental safety rules:
•do not touch the reverse osmosis purifying system with wet or damp hands or feet;
•do not (dis)connect the plug to/from the socket with wet hands;
•do not pull the power cord to disconnect the plug from the power outlet;
•do not leave the reverse osmosis purifying system exposed to atmospheric agents;
•do not allow the reverse osmosis purifying system to be used by children without supervision;
•before carrying out any cleaning or maintenance operation, disconnect the reverse osmosis purifying system from the electricity mains
by taking out the plug from the power socket;
•in the event of a fault or poor operation, switch off the Osmo and do not tamper with it. Contact an authorized technician for any intervention;
if parts of the reverse osmosis purifying system are replaced, for maintenance or due to a fault, by an unauthorized technician, make sure
the parts comply with the legislation in force.

•The equipment should be used in compliance with the procedures described in the manual and never for purposes other than
those detailed in the manual;
•The user is responsible for installing, operating and servicing the equipment in accordance with the instructions listed in this
manual;
•Only use genuine manufacturer spare parts dedicated for this product;
•Do not drink the water produced by Osmo;
•Do not block or crush the inlet or outlet pipes of the equipment or the sterilizer;
•If the water dispenser is not used (manual filling) we recommend closing the spiral tube’s connecting tap;
•If the equipment is not operated according to the instructions in this manual or is not properly maintained, the manufacturer
cannot be held responsible for any fault, damage or malfunctioning of the equipment;
•If the tap water shows high quantities of turbidity, chlorine, iron and manganese, silicon, or a level of TD (Total Dissolved
olids) above 2,000 ppm, the effectiveness and above all the life-span of the osmotic membrane will be significantly affected;
•Do not use the device with water over 20 °C;
•If the device is not used continuously it may emanate unpleasant smells.
This manual is an integral part of the product and must be kept close to the equipment for easy and quick reference. The
equipment is to be used only for the purpose for which it is designed.
Osmo: equipment designed for the demineralization of tap water.

RELIMINARY INSTALLATION INSTRUCTIONS
Wall-mounted installation
The water demineralizer should be fitted in a vertical position either beneath a sink or in a cabinet.
For mounting, use the supplied dowels and screws.
Install on the wall leaving a space of at least 10 cm from the floor or the bottom surface so that the filter cartridge can be dismantled.
Overall dimensions
ower supply
The equipment is supplied with 230 V ac or 115 V ac and the maximum power absorbed is 138 W.
Hydraulic installation
Drain
Install a drain nearby to dispose the waste water discarded by the osmotic membrane (max 1.5 m).
W Valve
The safety valve (Water Block®) prevents a water flow greater than the set value, which is the flow requested by the appliance connected.
This prevents big leaks in case a vessel or a tube gets broken. The Water Block is also fitted with a special check, preventing the return of
water into the hydraulic system and possible consequent contamination.
For this purpose, the WB valve must be installed in a vertical position (refer to section 9).
Charge
The installation of the product with inlet water pressure above 5 bars, can drastically reduce the lifespan of the equipment.
In case the inlet water pressure is more than 5 bars, install a suitable pressure reducer.
