ELECTRICAL INSTALLATION
2.4.1
GENERAL INFORMATION FOR ELECTRICAL INSTALLATION
Execute the connection as indicated in the wiring diagram. Factory connection must not be changed!
The degree of protection of electric parts of the heater is IP 44. Power input of electric element is 2200 W.
Figure 5
It is necessary to observe the below requirements during the electric wiring.
•
Heater
is connected to 230V/50Hz power supply via a fixed movable cable (depending
on the method of wiring)
•
The circuit must contain a breaker disconnecting all poles of the network, and a circuit
breaker (protector).
•
Installations in bathrooms, lavatories and showers must comply with the standards
that require that the heater is fitted with a safety terminal for connecting via protective
conductor of yellow

Access to
the power section of the heater is only possible once the heater is disconnected
from the power supply and the cover of the heater unscrewed.
•
Adhere to the protection against electric shock injury according to standard.

OPERATION
After the heater is connected to electric network, the heating element starts heating water. The element
is turned on and off by a thermostat. After reaching the temperature set, the thermostat switches off the
electric circuit and thus discontinues water heating. The control light signals if the element is in operation
(light is on) or if it is off (the light goes out). In case of longer operation without using the heated volume,
the thermostat has to be set to position 5°C to 8°C (set the “snowflake” symbol on the thermostat selector)
to avoid its freezing, or electricity supply to the heater has to be switched off. Setting the thermostat
to the 0 symbol doesn't mean that the appliance has been turned off.
