* To be borne in mind when carrying out anchorage to the wall
1.2. Installation instructions
Installation shall comply with official regulations such as the “Low Voltage Electrotechnical
Regulations”, the Technical Building Code and the local Regulations applicable. In
particular for installation in a bathroom or toilet, the volumes established by the “Low
voltage electrotechnical Regulations” shall be respected.
• No switches, current outlets nor lighting appliances shall be installed in prohibition
volume (fig 1) page 12.
• No switches shall be installed in the protection volume (fig.2), page 19, but safety current
outlets may be installed.
1.3. Product localisation
The thermo should be located as close as possible to the hot water outlets to avoid heat
losses in the piping.
The TNC electrical water heater shall always be installed vertically, with the water
connections below (see fig. 7), page 19, except the models TNC 80 H, TNC 100 H and
TNC 150 H, that will always settle in horizontal, also with the water connections down (to
see fig 8), page 16

To make things easier, the revision and internal cleaning there should be a free space at
least 25 cm between the protection cover (pos.13, figs. 7, page 22) of the electrical water
heater and any fixed obstacle.
1.4. Placement and securing
To anchor the thermo to the wall (see elevations on page 13), use 2 tacks and screws
which are sufficient to bear the weight of the thermo when filled with water (see
“characteristics” table page 3).
1.5. Installation of water system
When installing the water piping, follow the basic rules for preventing corrosion: “Do not
use copper or brass before iron or steel in the water circulation direction”. To avoid
galvanic pairs and their destructive effect, screw two tubes of the thermo (as seen in the
drawings in figure 7, page 22) and deploying Teflon tape, the insulating sleeves (pos.12)
supplied along with the thermo.
Screw the insulating sleeve of the cold water entry direction (blue) of the thermo, the
hydraulic security unit with an emptying device (pos. 8. figs. 7, page 22) supplied with the
thermo. Install a cutting key alongside the water pumping tube as seen in the drawings
(figs. 7 pos. 10, page 22).
Connect the hot water distribution pipe to the insulating sleeve of the hot water conduit of
the site.
The unit or hydraulic safety valve, supplied with the thermo, contains a retention and
overpressure valve. The latter opens as a maximum at 8 bars. If the pressure in the water
installation exceeds 5 bars, install a pressure reducer as indicated in the standard.
The widespread use of anti-return valves in the stipulations of the sanitary water system,
bringing about a strong increase in pressure by dint of the heating process; in these cases
it is vital to conduct the drain of the safety valve to an excavation pipe provided with a
siphon (figs. 7, pos.9, page 22); this tube shall be put in the open air and shall be installed
on a continuous slope until below.
The emptying of the lever can be carried out using the corresponding thermo (1).
Check the watertightness of all connections

1.7. Electrical installation
Ensure that the electrical voltage available is 230 / 50 Hz
The connection cable of the thermo has a Schuko type pin with earth outlet side contacts.
Make sure that the current outlet is a suitable connection base for the pin and that the
three conductors (one being earth) up to the connection base have enough section for the
power to be consumed
Make sure that the electrical installation has the regulatory differential switch (fig.6, page
14).
The power cable is of the type H05 V V F 3 x 1 mm white
1.8. Coming on line
Fill the thermo with water, opening the cold water stopcock and the hot water taps. When
water comes out of the latter, close them, starting with the lowest (bidet) and finishing with
the highest (shower). In this way the air shall be eliminated from the thermo and the piping.
Connect the thermo connecting the pin. The pilot lamp (pos.7, figs. 7, page 22) on means
that the water is being heated up; if off, this means that all the hot water is at the
temperature selected in the regulation thermostat (pos.11, figs 7, pages 22).
1.9. Conservation
It is vital that the Technical Assistance Service (SAT) annually revises its thermo to
eliminate the lime deposited in the heating element (pos.5, figs. 7, page 22) and check the
status of the magnesium anode (pos.5, figs. 7, page 22). If the water in your area is very
hard and corrosive you should ask for more frequent revisions.
If the magnesium anode of your thermo is very worn, the SAT shall replace it with a new
one.
Don’t forget to regularly operate the pressure valve so as to prevent it from blocking using
lever no. 1, a safety valve device for emptying water from the thermo (page 4).
To clean the exterior of the thermo you should use a damp cloth with soapy water. Do not
use abrasive products or those which contain dissolvents (for example, alcohol).
For safety reasons, COINTRA GODESIA, S.A is not responsible for using any other
elements which are not of origin and installed by your Technical Assistance Service.
1.10. Thermostat adjustable from the exterior
The exterior temperature regulating thermostat is situated inside the thermo
To increase the temperature of the accumulated water, turn the control clockwise and
anticlockwise to reduce it.
