FIRST COMMISSIONING
Once the tank is connected to water supply system and power supply, and safety valve tested (accordingly
with the manual attached to the valve), the heater can be put in operation.
Procedure:
a)
check the water main and wiring;
Check proper placement of thermostat sensors.
The sensors in
the well must be inserted all the way in; first the operating and then the safety thermostat.
b)
open the hot water valve on the combination faucet;
c)
open the cold water inlet valve to the tank;
d)
once water starts draining through the hot water valve, filling of the tank is completed and the
valve must be closed;
e)
if a flange lid leak is discovered, the flange lid bolts need to be tightened;
f)
fasten the electric installation cover;
g)
when hot sanitary water is heated by
electric energy
, switch on the power supply (the valve on the
heating water inlet to the heating insert must be closed in combined tanks).
h)
when sanitary water is heated with
electric energy
from hot water heating system, turn off
electricity an open the valves on the heating water inlet and outlet, possibly de
-
aerate the
exchanger.
i)
once the operation restarts, keep flushing the tank until the cloud disappears;
j)
make sure to fill in properly the warranty certificate.

CLEANING OF TANK AND
EXCHANG
E OF ANODE ROD
Repetitive water heating causes limestone sediment on both the enamelled tank walls and chiefly the
flange lid.
Lime scale settling depends on hardness of heated water, its temperature and on the volume of
hot water used.
We recommend checking and cleaning the tank from scale and eventual replacement of
the anode rod after two years of operation.
The anode life is theoretically calculated for two years of operation; however, it changes with water
hardness and chemical composition in the place of use.
Based on such an inspection, the next term of
anode rod exchange may be determined.
Have a company in charge of service affairs deal with the cleaning
and exchanging of the anode.
When draining water from the tank, the combination faucet valve
for hot
water must be open, preventing the occurrence of under
-
pressure in the tank receptacle which would stop
water from draining.
