ELECTRICAL CONNECTION

Before the electrical connection is made, the storage tank must be completely filled

with water!

CAUTION: You must disconnect the power before any intervention in the water

heater!

The electrical connection must be made according to the valid provisions and standards.

The water heater is connected to the mains via the connection cable.

In some cases, it is necessary to replace the installed connection cable with a new cable.

To do this, the plastic casing of the water heater must be removed. In order to remove this,

first remove the plate on the front of the casing by carefully inserting a spanner in the slot

between the plate and protective cover, first at the thermostat knob and then opposite from

the knob. If the plate is loosened on both sides, it can be removed by hand. Then remove

the thermostat knob and remove the fastening screw below the knob. Last unscrew all four

fastening screws and the casing can be removed. Now the installed connecting cable can

be removed from the connecting terminal and replaced with a new cable.

It should be noted that in case of failure (body circuit / leakage) it can trigger the RDC

(Residual Current Device) come. This means that all electrical equipment is energized in

this circuit.

Therefore, a separate RCD must be provided for the operation of the small memory should

other electrical equipment to be used, in which an uninterruptible power supply must be

guaranteed, as Freezers, refrigerators for medicines, emergency lighting, etc.
