FIRST COMMISSIONING
Before connecting to the electricity, the heater 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 up process the water that
increases its volume during the heating must visibly
drip off the safety valve. When heating is finished, the set temperature and the actual
temperature of consumed water should be roughly equal. When the heater is connected
to a water piping, power grid and the safety valve has been tested, the heater can be put in
operation.
Before the first putting into service or after a longer shutdown, the appliance has to be rinsed
out and flushed yet before the heating is activated. Before the heating starts, the heater must
be completely filled with water and the system properly flushed and vented. First heating
of the heater has to be watched.
Procedure of putting the heater into operation:
1.
Check the water main and wiring. Check proper placement of the operating
and safety thermostat
(thermal fuse) 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 mixing faucet.
3.
Open the cold water inlet valve to the tank.
4.
As soon as the water
starts running through the hot water valve, the heater is filled and the valve
can be closed.
5.
In case of leakage (of flange lid), we recommend that the flange lid bolts are fastened.
6.
Screw down the electric installation guard.
7.
Turn on the power supply.
8.
When commencing operation, flush the heater until the cloudiness in the water is gone.
9.
Make sure to fill in properly the warranty certificate.

PUTTING OUT OF SERVI
CE, EMPTYING
If the heater is put out of service for longer period, or is not going to be used for some time, we
recommend it is disconnected from the power grid on all poles. The switch for the power cord
or fuse machines must be shut down.
In locations that are permanently exposed to frost, hot water tank shall be emptied prior
to the beginning of the cold season, if the appliance is not used for several days, and if the power
supply is disconnected.
