FIRST COMMISSIONING
To connect the tank to water supply system, hot water heating system, power supply and,
after testing the safety valve (accordingly with the manual attached to the valve), the tank
can be put in 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 must be more
-
or
-
less the same.
Once the tank is connected
to water supply system and power supply, and the safety valve tested (accordingly with the
manual attached to the valve), the tank can be put in operation.
Putting the tank in operation:
1.
Check both water and electric installation; for combined tanks, check also the installation to
the hot water heating system.
Check proper placement of thermostat sensors.
The sensors in
the thermowell have to be inserted all the way.
2.
Open the hot water valve on the combination faucet.
3.
Open the cold water inlet valve to the tank.
4.
Once water starts draining through the hot water valve, filling of the tank is completed 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.
When heating utility water with heat energy from the hot water heating system, open the heating
water inlet and outlet valves, or de
-
aerate the exchanger.
8.
Once the operation restarts, keep flushing the tank until the cloud disappears.
9.
Make sure to fill in properly the warranty certificate.

PUTTING OUT OF SERVICE
, DISCHARGE
If the hot water tank is put out of service or is not used for longer time, it has to be emptied
and disconnected from power supply at 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 cold season, if the appliance is not used for several days, and if power
supply is disconnected.
Drainage of utility 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, be aware that not only the water in the hot
water tank and the water in the hot water piping may freeze, 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
.
