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.
The product is attached with a safety valve, 2 spiral dives 6x70 and 2 plastic wall plugs 12x60.
The above parts are packed and placed in the packaging together with the heater. It is in
your own interest to check the completeness of the accessories.
Procedure of putting the heater into operation:
1. Check the wiring and water supply; check correct position of the thermostat sensors, they have to
be inserted all the way. 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 heater.
4. As soon as the water starts running through the hot water valve, the heater is filled and the valve can
be closed.
5. Prior to putting the heater into operation, screw on the front heater guard which closes the access
to the electric compartment of the heater.
6. In case of a leakage (flange lid), we recommend fastening the flange lid bolts.
7. Screw down the electric installation guard.
8. When hot service water heating by electric energy, switch on the power supply.
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.
2.6 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.
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 water heater 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.
