2.5 PUTTING THE HEATER INTO OPERATION

Before opening the power supply, the tank must be filled with water. The process of first
heating must be executed by licensed professional who has to check it. Both the hot water
outlet pipe and safety armature parts may be hot.
During the heating process the pressurised connection water that increases its volume due
to heating must drip off the safety valve. In non-pressurised connection water drips off the
overflow combination faucet. When heating is finished, the set temperature and the actual
temperature of consumed water should be roughly equal. After connecting the heater to the
water main and electrical power system, and after checking the safety valve (following the
instructions attached to the valve), the heater can be put into operation.
Before fist putting into service or after a longer shutdown the appliance has to be rinsed out
and flushed yet before heating is activated. Before heating starts, the tank must be
completely filled with water and the system properly flushed and vented. First heating of the
tank has to be watched.
