Example with a vertical wall-mounted water heater

EN It prevents the safety unit’s valve from opening erratically when the water heater is not operational. To determine the water pressure in your house. You can find out more from your water supplier

The pressure reducer is an additional accessory which should be installed at your water meter’s outlet if the water pressure in your house is greater than 5 bar (0.5 MPa).

Warning: the pressure limiter must never be positioned between the safety unit and the cold water inlet

Waste water drainage (drains)

Safety unit The safety unit is a mandatory accessory. Its role is to maintain an interior water pressure of 7 bar (0.7 MPa) to prevent explosion (it fulfils the same role as a valve on a pressure cooker). The safety unit therefore lets water escape when the water heater is operational. This flow may represent up to 3% of the volume of the water heater cycle. Caution: the safety unit must always be directly connected to the tank’s cold water tank. Nothing should be fitted between the safety unit and the water heater. (no valve, no pressure limiter, etc.).

EN Installation Manual: Connecting the water heater to the electricity

5. Connecting the water heater to the electricity SWITCH OFF THE ELECTRICITY!

Check the compatibility of the water heater with the electrical installation.

If the water heater is pre-wired, connect the water heater’s power supply cable to a cable outlet (the water heater should not be connected to a socket).

NO If the water heater is not pre-wired, the use of a rigid cable connection with a minimum cross-section of 3 x 2.5 mm2 in single-phase (phase, neutral, earth) or 4 x 2.5 mm2 in three phase (3 phases + earth) is essential (refer to the «wiring diagram» section).

Check that the water heater is full by turning on a HOT water tap. COLD water should flow out. If the water heater is switched on when it is empty, there is a risk of damage (not covered by the warranty).

Switch the electricity back on.

A direct connection to the resistors (without passing through the thermostat) is strictly forbidden as it is extremely dangerous, the water temperature would not be limited.

6. Commissioning the water heater

If your electrical distribution board is equipped with a day/ night switch (reduced night tariff), move it to 1 (forced operation).

There may be some light smoke when heating starts (NORMAL operation). 8

After a while, water should flow drop by drop through the safety unit (connected to a waste water drain pipe). During heating, and depending on the water quality, the water heater can emit a sound similar to that made by a kettle. This sound is normal and does not mean there is a fault.

Wait for heating to finish before using your water heater fully (see specifications table to determine the estimated time depending on your model). 42
