Procedure of putting the appliance into operation:
1. Check both water and electric installation; for storage tanks, 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 the 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 appliance.
4. As soon as the water starts running through the hot water valve, the appliance is filled and the
valve can be closed.
5. In case of a leakage (flange lid), we recommend fastening the flange lid bolts.
6. Fasten the electric installation cover.
7. 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.
8. When commencing operation, flush the appliance until the cloudiness in the water is gone.
9. Make sure to fill in properly the warranty certificate.
2.7 PUTTING OUT OF SERVICE, DISCHARGE
If the hot appliance 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 appliance 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.
Drainage of service water shall be performed after closing the shut-off valve in the cold
water supply piping (through the discharge valve for safety valve combination), and with
simultaneous opening of all hot water valves of connected fittings. Hot water may outflow
during the drainage! If there is a risk of frost it has to be considered that not only the water
in the hot appliance and in the hot water piping may get frozen but also the water in the
entire cold water supply piping. It is therefore advisable to drain all fittings and piping that
carry water, up to the part where the house water meter is installed (connection of the
house to water main) which is not jeopardised by frost. When the tank is to be used again, it
has to be filled with water and one needs to make sure that the water flowing out at the hot
water valves did not contain any bubbles.
