Thanks
Lamber thanks you for the confidence you have shown by buying one of its products.
Your water purifier is conceived to have a long life.
You will find into this manual all necessary information concerning installation, start, functioning, maintenance and repair
of the appliance.
Technical impossibilities
ØYou have to connect the appliance to cold water from 2 to 25°C max.
ØWater hardness : 20° TH max. –Above 20° TH it is necessary to install a water softener.
Regulate water outlet at 0° TH
ØWater purifier’s feed water pressure with a capacity of 600 l/h minimum :
2 dynamic bars minimum
10 static bars maximum
ØMaximum conductivity of the water that you want to treat: 2000 µS/cm.
ØAmbient temperature of the room: 43°C maximum.
ØDo not make the distribution line where the purified water exits by copper or galvanized steel, but only by PVC or
stainless steel.
Application limits in glass washing
ØChampagne flûtes , beer glasses :
The absence of mineral deposits on the glasses prevents bubbles formation and foam stabilisation (possible solution:
use of pre-scored glasses or use of a diamond-point pencil, code SPDCTA, to score the glasses).
ØParticular drying case:
Rinsing with demineralized water (so with almost complete absence of surface-active product) produces a less good
drying result than with a non-treated water. So it is recommendable to think about a place and a time for baskets
storage. This place for storage of glass baskets should be well ventilated, so to have a good drying for evaporation
ØDetergents and surface-active products:
Manual dosing is not compatible.
Only a proportional dosing with products suited for purified water is effective.
Tests for dosing should be carried out whatsoever is possible together with the supplier of detergents and rinse aid
additives.

Storage tank connection
The explanation is here provided with a 20L stainless steel storage tank.
The assembly is the same for all models.
1. Screw the T with teflon on the outlet hose
2. Connect the flexible machine feed hose on the T.
ØPressure tanks create a purified water stock always available and assure an optimal preservation
of the purified water quality, safe from ambient air.
ØThe internal membrane ( pre-charged at 2,5 Bar) allows to return the under pressure stocked
water directly, without booster pump
ØThey allow the RO400C to function on longer and less frequent cycles, so to have a water and
energy economy, a longer life of the parts that wear down and a better quality water.

Manuel Technique OsmsoeurRO400C Version 3 Page 9/ 26
Installation
Attention :
-Do not connect to electrical supply,
-Make sure the ¼ turn valve is closed,
-Do not carry out any connection on the appliance’s inlet or
on the storage tank.
1. Open the feed water supply, the water purifier
is under hydraulic pressure.
2. Connect it to electrical supply.
3.The water purifier, after a LED test, will flush
(about 30 sec.).
FLUSHING
The flushing operation should be carried out in the following cases:
•the first time RO400C is used ;
•put back on working after storage ;
•after a descaling ;
•after replacing the membrane;
4. When the flushing finishes, disconnect and then
connect the water purifier to electrical supply.
RO400C flushes again for 30 sec.
5. Repeat twice the previous operation to carry out
3 flushing cycles in all.
The water purifier stands-by when green ON/OFF led is lighted up.
CALIBRATION
Calibration of water purifier should only be carried out :
•the first time the RO400C is used;
•if the appliance is moved to a different place (so different inlet water);
•After the membrane has been replaced.
6.Direct the purified water hose to a drain.
Open the purified water valve and within 10 seconds press
“Calibration”button and keep it pressed till “Purification Level”
lights I and II light up and then go out.
After having released the button, the water purifier products
water without any indication of the purification level; this is the
calibration.
7.Let the water flow till when the green «purification level III » light
lights up.
This takes about 10 minutes.
8.When the green «level III » light lights up, close the purified water valve, a
flushing operation will start.

goes under 3 Bar.
The end. The water purifier is ready to start working.

Manuel Technique OsmsoeurRO400C Version 3 Page 11 / 26
Maintenance
Even if everything has been conceived so that to be forgotten, your water purifier requires a minimal care.
Here is the regular maintenance that RO400C requires so to produce a high quality water:
Information below concern a water purifier that is fed with softened water.
ØTo clean the grid : At every filter replacing (1 or 2).
ØTo replace filter 1 : At least every 6 months or when the water purifier requires it (see “Trouble-
shooting table”).
ØTo replace filter 2 : At least every 6 months, or every 2000 functioning hours, or when the water
purifier requires it (see “Trouble-shooting table”).
ØPreventive descaling : Every time you replace filter 2.
ØCurative descaling : If the purified water’s capacity decreases till being half of the original
capacity, even if the preventive descaling has been regularly carried out.
ØTo replace the membrane : If the purified water’s capacity decreases till being half of the original
capacity, even if the curative descaling has been regularly carried out.
Qualified technician only.
ØPreparation to storage and protection against freezing:If the water purifier will not be used for a long time
(for ex. annual closing). To repeat it every 9 months in case of long non-use.
To clean the grid
The grid ( a coarse filter) is conceived to intercept large particles; it’s located inside the union where you connect the
RO400C’s feed water hose. If the LEDs on the control panel show that the intake pressure is too low, the reason may be
that the grid is clogged.
1. Disconect the appliance from the electrical supply.
2. Unscrew the flexible feed water hose, on the back of the
appliance.
3. Use suitable pliers to grip and remove the grid (picture A).
4. Clean the grid. Then put it back inside the connector.
5. Reconnect the feed water hose to the appliance.
6. Connect the RO400C to the electrical supply.
The water purifier will flush automatically.

Manuel Technique OsmsoeurRO400C Version 3 Page 12 / 26
Replacing the filters
Replace the filters when the water purifier requires it (see diagnostic section) and at least once
every 6 months.
1. Disconnect the electrical plug.
2. Pull the filters containers support outwards as far as they will come.
3. Use the filter spanner to unscrew the container of the filter to replace. Bear in mind the container will be full
of water, so hold with the other hand the group to avoid some water to spill.
4. Dry the base under the filters to avoid the flow-stop.
5. Clean the filter container and replace the filter, with label I or II pointing upwards.
6. Make sure the sealing ring is in place in the grooves of the filter container.
7. Refit and tighten the container by hand ; the dot should be between the 2 white lines.
8. Slide the filter containers back into the appliance.
9. Close the front cover and reconnect the electrical plug. Flushing will take place.
Attention : After filter II replacing, you have to reset the water purifier.
The water purifier should be under hydraulic pressure and connected to the electrical
supply and it should not be producing purified water or flushing.
Then press « Calibration » button and keep it pressed until the indicator light for filter
II has gone out (about 5 seconds).

Descaling
In time, the substances which RO400C removes from the water tend to clog the membrane and so to reduce the flow of
pure water.
To prolong the life of the membrane, it has to be descaled (preventive
descaling)periodically. The frequency of preventive descalings depends mainly
on feed water’s hardness.
If a preventive descaling is not enough to restore the original flow of purified
water, it would be better to do a curative descaling.
The correct descaling product for RO400C can be ordered from your dealer. Item : OSMONET
Preventive descaling (about 30 min.)
1. Disconnect the electrical plug. Remove the filters and refit the empty containers.
2. In a bucket mix 200gr of OSMONET with 2,5 litres of lukewarm water. Stir until the powder has dissolved.
3. Disconnect the flexible feed hose, the drain hose and the purified water hose and insert them in the bucket.
4. Connect again the electrical plug. The appliance will flush.
5. Disconnect the electrical plug after 30 seconds or after putting under safety of the water purifier (luck of
pressure)
6. Wait for 2 minutes. The descaling product operate.
7. Repeat 3 times points 4, 5 and 6.
8. Refit the filters and wash the nuts of the flexible feed hose. Reconnect flexible feed hose and drain hose.
9. Repeat 2 times operations 4 and 5 to rinse the water purifier.
10. Wash and reconnect the purified water hose and then reconnect the electrical plug. The water purifier is
ready again to work.

Curative descaling (about 10 hours)
If a preventive descaling is not enough to restore the original flow of purified water, it’s necessary to do a curative
descaling.
This operation is the last way you have before having to replace the membrane.
Depending on the membrane’s state, the nominal flow won’t be systematically restored (clogged membrane) or (worn
membrane).
1. Shut off the tap for purified water.
2. Disconnect the hose for purified water from the appliance (disconnect before the non-return valve if a storage
tank is installed).
3. Disconnect the electrical plug and then plug it back again to make the appliance switch to flushing mode.
4. Let the water purifier flush.
5. Unscrew the container of filter II as described under “Replacing the filters”.
6. Put 200gr of OSMONET (the descaling agent) into the container. Fill the container almost to the top with
lukewarm water ( 20° to 40°C). Stir until the powder has dissolved (picture A).
7. Screw the container (filled with the descaling solution)into place with the aid of the filters spanner.
8. Open the tap for purified water and let RO400C operate for 45 seconds.
9. While the tap is still open, disconnect the electrical plug. Then close the tap. Don’t touch the water purifier for
10 hours ( for example during the night).
10. At the end of the 10, unscrew the container. Discards its content and rinse it with water.
11. Put a filter II in the container; refit and tighten the container by hand.
12. Connect the electrical plug and let the water purifier finish the flushing operation.
13. Open the tap for purified water and let the water flow for 10 minutes. Then close the tap. The water purifier
flushes for some minutes.
14. Connect the hose for purified water to the appliance ( or the non-return valve if a storage tank is installed).

Manuel Technique OsmsoeurRO400C Version 3 Page 15 / 26
Preparing the water purifier for storage and protecting it against
freezing
If you should not use the water purifier for a period longer than 4 months or if it has to be disconnected from water and
electrical supplies for many days, it should be filled with a special product that will keep it in good state.
1. Make sure that the tap is closed and the water purifier is
not flushing.
2. Close the cock on the water supply pipe. Disconnect the
electrical plug, the flexible feed water hose and the
drain hose.
3. Unscrew both filter containers. Remove the 2 filters and
discard them ( they should not be kept for re-use!).
Empty the water from the containers.
4. Reinstall the empty filter containers back in their places.
Make sure that each sealing ring is in place in the groove
on the top edge of each container.
5. In a bucket, mix 2 litres of Preservative Liquid (Code
LCRO400C) with 2 litres water.
6. Put the end of the 2 hoses (feed and drain) into the bucket.Make sure that the end of the feed water hose
remains beneath the surface throughout the operation (picture C).
7. Connect the electrical plug again. RO400C will now automatically pump the mixture inside the appliance. Let the
water purifier suck for 40 seconds, then disconnect the electrical plug. Repeat twice this step.
8. If some mixture remains in the bucket, you can throw it in the wash basin.
RO400C is now ready for storage, for up to nine months.
When the water purifier is to be brought back into use, you must:
•work through all the steps of the full « Flushing » procedure, to remove the preservativeliquid.
•install new filters (filter I and filter II).

•Use of pre-scored glasses
•Use of a diamond-
point pencil, code SPDCTA,
to score the glasses.
Bad drying
Rinsing with demineralized water (so
with almost complete absence of
surface-active product) produces a
less good drying result than with a
non-treated water.
•Think about a place and a time for baskets
storage
•The place for storage of glass baskets
should be well ventilated,so to have a good
drying for evaporation
Spots on glasses
Not correct dosing of detergents
and/or rinse aid additives.
Purified water needs less products
for the same action.
•Manual dosing is not compatible.
•Only a proportional dosing with products
