2.6 FIRST COMMISSIONING

After connecting the heater to the water supply, the hot water heating system, the electric

network, and after testing its safety valve (based on the valve manual attached), the heater

may be put 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.
