* 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

1.6. Description of safety valve

1. - Appliance for emptying water from the thermo Entered direction

cold water

2. - Outlet of mouth or emptying.

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.
