Upon connecting the water heater to the water supply
system, take care of the indicative color markings /rings/
of the pipes:
BLUE - for cold /in-flowing/ water,
RED - for hot /out-flowig/ water.
The mounting of the safety return-valve supplied with
the water heater is obligatory. The safety return-valve
must be installed on the cold water supply pipe,
according to the arrow stamped on its body that
indicates the supplied water direction. Additional
stopcocks must not be mounted between the safety
return-valve and the water heater.
ATTENTION! Any other /old/ safety return-valves
may lead to a failure of your appliance, therefore
they must be removed.
ATTENTION! Fixing the safety return-valve to
threads longer than 10 mm is not allowed, as it
could damaged the valve and could make the use of
your appliance dangerous.

cold water supply system and the tap on the hot water
mixing faucet. After the filling process is complete, a
constant stream of water should flow from the water-
mixing faucet. Now you can shut the hot water tap on
the mixing faucet.
When you must empty the water heater, you should first
cut it off the power supply.
