We recommend that the hot water distribution from the heater was as short as possible
to minimise heat losses.
Heaters TO/E UP must be provided with a discharge valve mounted on the cold service water
inlet to the heater for potential disassembly or repair.
When assembling the security equipment, follow the standard.
8 ELECTRIC INSTALLATION
The wiring diagram is attached in the manual to the water heater (Figure 4). The heater must be connected
via a separate supply with a front-end main switch. The heater is connected to 230V/50Hz electric network
by a wire with a plug into the socket. The electric installation must comply with the applicable electrical
standards. The connection of the heater to the electric network must be made after the water heater
is installed and the heater is filled with water.
Follow the rules of protection against electric shock in accordance with the ČSN 33 2000-4-41 standard.
The degree of protection of electric parts of the heater is IP X5.
