2.6 PUTTING THE HEATER INTO OPERATION
After connecting a heater to the water main, 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.
Procedure:
1. Check both water and electric installation; for combined heaters, check the installation to a hot
water heating system. Check proper placement of operating and safety thermostat sensors. The
sensors must be inserted all the way in; first operating and then the safety thermostat.
2. Open the hot water valve on the combination faucet.
3. Open the cold water inlet valve to the heater.
4. As soon as the water starts running through the hot water valve, the heater is filled and the valve
closes.
5. In case of a leakage (flange lid), we recommend fastening the flange lid bolts.
6. Fasten the electric installation cover.
7. In case of service water heating by electric energy, turn on the electricity (for combined heaters,
the heating water valve at the heating water entry to heating insert must be closed).
8. When heating service water with electric energy from the hot water heating system, turn the
electricity off and open the valves of heating water input and output, possibly de-aerate the
exchanger.
9. When commencing operation, flush the heater until the cloudiness in the water is gone.
10. Make sure to fill in properly the warranty certificate.
2.7 PUTTING OUT OF SERVICE, DISCHARGE
If the hot water heater is put out of service for a longer time, or if it is not going to be used it
has to be drained and disconnected from the electric supply network on all poles. The switch
for the supply lead or the fuse cut-outs have to be shut off.
At places with permanent risk of frost the hot water heater must be drained before the cold
season starts if the appliance remains out of service for several days and if the power supply
is disconnected.
