Tanks must be provided with discharge valve
mounted on the cold sanitary water inlet to the tank
for potential disassembly or repair.
When assembling the security equipment, follow
the standard.

CONNECTION OF INDIRECT TANK TO HOT WATER SYSTEM
a)
Water heating by electric energy
When the tank
is connected to power supply, the heating element heats 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.
In combined tanks, the stop valve on the
inlet to the exchanger has to be closed at the inlet to the heat exchanger which prevents heating the water
in the hot water heating system.
