ELECTRICAL CONNECTION

Before performing any operations, disconnect the appliance from the electricity mains using the external

switch.

1. Electrical installation must comply with SANS 10142 – Electrical code for wiring of premises and should be tested

by the local electricity authority. The fixed wiring must incorporate a means of disconnecting from the main supply

having a separation of at least3 mm in all poles.

2. Check the circuit breaker on the distribution board is the correct amperage for the unit.

3. Check that all electrical connections are secure.

WARNING! THIS APPLIANCE MUST BE EARTHED.

4. Replace electrical cover and ensure geyser is full of water before switching on electricity, even for testing purposes.

5. Fixed wiring must incorporate a means of disconnecting from the main supply, having a separation of at least 3 mm

in a pole.

NOTE: Elements burn through commissioning without water and burnouts due to loose connections are not covered

by the guarantee.

For greater safety, have qualified personnel carry out a careful inspection of the electrical system, ensuring it complies

with the applicable norms in force, because the appliance manufacturer will not be held responsible for any damage

caused by the lack of earthing of the system or for faults in the electricity supply.

Check that the system is suitable for the maximum power absorbed by the water heater (please refer to the data plate)

and that the cross-section of the electrical connection cables is suitable and complies with current laws. The use of

multiplugs, extensions or adaptors is strictly prohibited. It is strictly forbidden to use the piping from the plumbing,

heating and gas systems for the appliance earthing connection.

If the appliance is supplied with a power supply cable and the latter should need replacing, use a cable featuring the

same characteristics (type H05VV-F 3x1.5 mm

it until it reaches terminal of the thermostat, then lock single cables by mean of the insulation base. To disconnect the

unit from the electrical supply use a bipolar, switch conforming to local (contact opening at least 3 mm, better if equipped

with fuses). The appliance must be earthed and the earth cable (which must be yellow-green and longer than that of

the phases it is fixed to the terminal marked by the symbol

the special wire clamp provided. Before usage, make sure that the supply voltage is in compliance with the rated

values of the appliance. If the appliance is not supplied with a power supply cable, use a flexible cable (type H05VV-

F 3X1.5mm

, 8.5 mm) in diameter compliant with the applicable norms in force, if the applianche is supplied with a

cable clamp.

Startup and commissioning

Before powering up the appliance, fill the heater with mains water.

To do so, open the mains cock and the hot water tap until all the air has been vented from the boiler. Check for leaks

from the flanges, tighten down the fittings (not too much!) if necessary (A fig. 4).

Power up using the switch and in models with no switch, power up by turning the adjustment knob clockwise

MAINTENANCE REGULATIONS (for competent person)

CAUTION Observe all general warnings and safety standards listed at the

beginning of this text in full; all such instructions are obligatory.

Maintenance work may only be done by qualified technicians (in possession of the regulatory requisites).

Before requesting for the Technical Assistance to intervene for a suspected fault, check that this is not caused by a

temporary lack of water supply or power failure.

Draining the appliance

Make sure to drain the appliance when it is out of service or in an area subject to subzero temperatures.

To drain the appliance, proceed as follows:

- permanently disconnect it from its power supply;

- open the hot water tap (sink or bath tub).
