FIRST COMMISSIONING
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 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 supply system, power grid and the safety valve tested (accordingly with the manual
attached to the valve), 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 tank must
be completely filled with water and the system properly flushed and vented. First heating
of the tank 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
sensors. The sensors must be inserted all the way in the thermowell; first the service thermostats
Te2, Te1 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 hot water tank 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 supply
lead or the fuse cut
-
outs have to be shut off.
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.
