1. INTRODUCTION
This manual explains the installation and operation of equipment made by HI-
DRO-WATER, S.L. for water treatment by ultrafiltration for household use. The equip-
ment has been designed to be connected to the housing facility.
It is easy installation and operation as it has already been semi-assembled. It
requires very little assembly as it is only necessary to connect the hydraulics and install
the faucet as indicated in point 4 of this manual.
In the absence of installation and maintenance as described in this manu-
al by technically qualified personnel to ensure the quality of water produced and
proper installation, the warranty is void.
2. PRECAUTIONS AND WARNINGS
Please read this manual carefully following the warnings listed below before going
ahead with the installation and use of the NELVA ultrafiltration system. If you have any
doubts, please contact an official HIDRO-WATER S.L distributer.
•For the correct operation of osmosis systems with a pump, the pressure should
be between 2.5 and 4 bars.
•The temperature of the water to be treated should not be below 4ºC nor above
40ºC to avoid damaging the system.
•The ultrafiltration system is designed to treat tap water with a maximum salinity
of 1500 ppm. Do not use in places where the water is not microbiologically safe
or has an unknown quality. For water with a greater salinity level, please con-
tact an official HIDRO-WATER S.L distributer.
•It is advisable that the water to be treated has been softened or with a maxi-
mum hardness of 15ºHF for optimum performance.
•If the water has a high concentration of iron or magnesium, nitrate concentration
greater than 100 ppm, sulphate concentrations greater than 250 ppm, more
than 3 NTU turbidity and/or prolonged use of high chlorine levels, please con-
tact an official HIDRO-WATER S.L distributer to suggest an appropriate pre-
treatment system to ensure the correct operation of the system.
•If the osmosis system is not going to be used for a long period of time, close the
water passage.
•Install the system on a flat surface.
•Do not expose the system to direct sunlight or install it outdoors.
•The installation should be done by professionally qualified personnel and should
not be installed close to a heat source.
•Do not repair or take the system apart on your own. If the system is not working
correctly, please contact an official HIDRO-WATER S.L distributer. Any tamper-

3
ing of the equipment by unauthorized personnel will result in the warranty being
void.
•Make sure the water passage is closed when a repair or maintenance is being
carried out.
•Do not bend the tubes to prevent flow and pressure blockages.
•Use original spare parts to assure the correct performance of the system.
•For installation, maintenance and cartridge change, please follow this manual;
otherwise the warranty will be void.

4. INSTALLATION
The system can be installed anywhere in the residence where there is a water
input, a drain for water waste and sufficient space to be located. The most common
place is under the kitchen sink. The installation should be carried out by qualified per-
sonnel.
4.1. Faucet installation (Figure 2)
a. Choose the location on the counter where you
want to install the faucet.
b. Use a drill with a 12mm bit to make a neces-
sary sized hole to put the faucet.
c. Fit the tap in the hole as indicated in the figure
using a spanner (our reference: OI-0207-128 not
supplied with system) to adjust it tightening the
nut.

4.2. Water inlet installation (Figure 13 & Figure 14)
a. The water supply input consists of two parts; a brass ball valve (Figure 5) and an
adaptor (Figure 4). The brass ball valve must be screwed to the adaptor using
sufficient Teflon on its thread, as shown in the figure below.
b. Turn off the water supply at the point where you are installing the ultrafiltration
system.
c. The water supply input is designed to be used with hoses with a ⅜” connection.
Insert the water feed adapter with the brass ball valve between the cold water
supply and the hose. (Never install a hot water connection as the ultrafiltration
system will be damaged). Make sure that the brass ball valve is closed.
4.3. Ultrafiltration system installation
The hydraulic connections should follow the contour of the surface cho-
sen for installation so that the tubes do not get mixed up or tangled. Leave a
sufficient length of tube to ease moving the system during future maintenance.
Here are the steps to follow to make the hydraulic connection:
a. Connect the ⅜” tube (Figure 3) to the water supply inlet (Figure 5).
b. The other end of the ⅜” tube should be connected to the pressure re-
ducer inlet (figure 10); to do so, you must remove the blue security clip
which is on the inlet of the pressure reducer and insert the tube fully.
Once you have introduced the ⅜” tube, replace the ⅜” plastic clip. (The
pressure reducer has a sticker with an arrow that indicates the way the
water should flow, then the pressure reducer inlet will be the way the ar-
row is pointing)

6
c. Connect the ⅜” tube (Figure 3) to the pressure reducer outlet (Figure
10); to do so, you must remove the blue security clip which is on the out-
let of the pressure reducer and insert the tube fully. Once you have in-
troduced the ⅜” tube, replace the ⅜” plastic clip.
d. You must connect the other end of the ⅜” tube to the inlet of the WA-
TER STOP Antileak system (Figure 8) where it’s marked “IN”, inserting it
fully. Once inserted, place the ⅜” security clip on it (figure 9).
e. The WATER STOP Antileak system (Figure 8)
must be fixed to the base of the place where
you’ve decided to put the ultrafiltration system.
To do so, you must use the double-sided tape
that is supplied inside the WATER STOP An-
tileak system box.
f. Once the WATER STOP Antileak system have been fixed to the chosen
place, you must connect the ⅜” tube to the WATER STOP Antileak out-
let (Figure 8) where it’s marked “OUT” fully. Once inserted, place the ⅜”
security clip on it (figure 9).
g. You must connect the other end of the ⅜” tube to
the ultrafiltration system (Figure 1) where it’s
marked “ENTRADA” (Inlet). To do so, you must
unscrew the straight nut on the system’s inlet.
Then insert the ⅜” tube through the nut and place
a plastic insert (Figure 6) in it. Screw the nut back
on the straight on the ultrafiltration system’s inlet.
h. Screw the faucet adapter (figure 7) to the faucet placing the
supplied O-Ring between the adapter and the stud. Insert ⅜”
tube through this adapter’s nut and ⅜” sleeve then insert a
⅜” plastic insert (Figure 6) in that end on the tube. Then you
must insert that end in the faucet’s adapter and tighten the
nut with the help of a wrench (Our reference: OI-0207-128,
not supplied with the system) or a spanner.

7
i. The other end of the ⅜” tube must be connected to
the ultrafiltration system’s outlet, which is marked
“GRIFO” (Faucet). To do so, you must unscrew the
straight nut on the system’s outlet. Then insert the
⅜” tube through the nut and place a plastic insert
(Figure 6) in it. Screw the nut back on the straight
on the ultrafiltration system’s outlet.
Here is a diagram of how the ultrafiltration system should be installed.
5. U LTRAFILTRATION SYSTEM START - UP
a. Make sure that all the connections are connected properly
and tightened.
b. Make sure that the arm of the WATER STOP Antileak sys-
tem is down like shown in the figure so that the water can
enter the ultrafiltration system.
c. Open the water supply and then the ball valve (fig-
ure 5) as shown. Make sure there is no water leak.
If there is, close the valve and fix it.
d. Open the faucet (Figure 2) and let all of the air out
from inside the ultrafiltration system. Once a contin-
ual water flow comes out of the faucet, let it run for 30 seconds and then close the
faucet. If in the beginning, the water runs black, don’t worry, this is normal, it’s
caused by the residue that the granulated carbon filter lets off. Drain this water. The
water will run clear not long after this.

8
e. Raise the arm on the WATER STOP Antileak system and
place one of the pieces of the absorbent material sup-
plied with the WATER STOP Antileak system. Keep the
other one safe as a spare part. Lower the arm of the sys-
tem so that water can enter the ultrafiltration system.
6. INSTALLATION & MAINTENANCE
The installer should inform the family members of the following points of the ul-
trafiltration System:
a. Location of the water inlet, pressure reducer, faucet and the WATER STOP Antileak
system.
b. Maintaining the osmosis system. The recommended maintenance of the ultrafiltra-
tion system is in the table below. By not following the maintenance as described
in this manual, using original HIDRO-WATER S.L cartridges and by authorized
personnel that guarantees the quality of the water produced and the correct
operation of the osmosis system, the warranty will be void.

Sanitation
Every time you change a cartridge, the membrane or a compo-
nent in contact with water or if you haven’t consumed water in
over a month, you must sanitise the system using the Sanitis-
ing kit (OI-0207-131). Not supplied with the system.
*The life of the filters and membranes will vary depending on the quality of the water
supply, the usage and the amount of impurities it has.
Replace the cartridges in the given period to ensure the life of the membrane and the
quality of the water obtained.

6.1. PROCEDURE FOR REPLACING CARTRIDGES AND THE MEMBRANE
a.Close the water supply brass ball valve (figure 5).
b.Open the faucet (figure 2) to relieve the pressure from inside the osmosis sys-
tem.
c.To change any of the cartridges and/or membrane they must be turned clock-
wise and pulled downwards to remove it from its cap as indicated in the follow-
ing figure. This process must be carried out for each of the cartridges that you
want to replace.
d. Remove the cartridges/membrane from their original packaging. Each cartridge
and/or membrane must be placed in the corresponding position maintaining
the correct order. To do so, you must insert each cartridge in its cap and turn it
anti-clockwise. This process must be carried out for each of the cartridges that
you want to replace.

10
e. Once you have replaced one of the cartridges/membrane – with the faucet
(Figure 2) open – open the brass ball valve (Figure 5) at the water supply. Let
all of the air out from inside the ultrafiltration system. Once a continual water
flow comes out of the faucet, let it run for 30 seconds and then close the fau-
cet. If in the beginning, the water runs black, don’t worry, this is normal, it’s
caused by the residue that the granulated carbon filter lets off. Drain this wa-
ter. The water will run clear not long after this. Check for leaks, if there are
any, close the valves and fix them.
Precaution 1: If there is any water leak in any area of the tube connections,
remove it and cut off 0.5cm. Then reconnect it. If the leak s
produced on any thread, unscrew the piece, apply more Teflon
and screw it back on.
6.2. PROCEDURE FOR REPLACING THE WATERSTOP ANTILEAK ABSOR-
BENT MATERIAL
In the case of having to change the WATER STOP Antileak absorbent
material; you must do as follows:
a. Raise the arm on the WATER STOP Antileak system, to cut off the water
supply (if there is a leak the arm will already be raised).
b. Throw away the current absorbent material.
c. Replace it with a new absorbent material.
d. Lower the arm on the WATER STOP Antileak system and it’s ready for use.
