CONNECTION OF THE CABLES
1. Turn off the main power supply.
2. The cover of the electric resistance is on the right hand side of the storage tank. Unscrew the two screws and remove the cover.
3. The thermostat is adjusted from the factory at 60°C. You can adjust it at the temperature you wish, by using the temperature control (34). In that case we advise that the temperature you will fix not to exceed 75°C.
4. Check the safety thermal switch (indication "F" or "S") on the thermostat. The safety switch is in operation when it is pushed in.
5. Connect the lug 2 of the thermostat to the lug "N" of the power line connector (blue cable). Connect the lug 3 of the thermostat to the lug "L" of the power line connector (black cable) - see diagram.
6. The grounding lug is connected from the manufacturer, as shown in the diagram. Ensure that it is well screwed.
7. Pass the wire through the hole of the cover (21) and connect the wires on the power line connector. Screw the cover (21) on the storage tank.
Attention:
The grounding lug ( ) on the power line connector, must be connected with the grounding wire of the building.
The power cable must be connected to a switchboard, of which the separating distance of the contacts is more than 3mm.
The standard power of the electric resistance is 4000W for 230V. Upon a special order, the electric resistance can be offered with power from 800W to 4000W. For power of 110V, the electric resistance is available (upon a special order) with power from 800W to 2000W.
Note:
A certified electrician must make all the electric connections.
Ensure that all the electric connections comply with the electric regulations applicable in your area and your building.
Do not turn on the electric resistance, when the storage tank is empty. |

ELECTRIC RESISTANCE WITH A BUILT-IN TUBE HEAT EXCHANGER |
  |
All models 120, 160, 200, 260 and 300 can be delivered, upon a special order, with a tube heat exchanger built-in to the electric resistance.
The tube heat exchanger can be connected with the central heating system for more energy saving.
The instructions of the electric connections are same to the ones of the electric resistance without a tube heat exchanger.
