Putting into service:
Before connect hydraulically the water heater to water network lets the water flow some to time to remove
all dirty which could damage the safety valve and block the diffuser.
To fill the water heater properly leave a hot water tap open to drain the water heater tank and only close it
when water comes out fluently. When water become hot after the necessary time tight again all connections to
assure a correct water sealing.
If the water network pressure is higher than the nominal pressure of the water heater, it is compulsory to
install special valve to reduce the water inlet pressure between 2 and 3 bar.
4.- CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK.
The connection of water heater to the electric network must be performed according to standards for
electric installation and made by authorized installers.
These models must be connected to electrical network using a plug supplied assembled to the water
heater. According to this the sole necessary operation from electrical point of view is to plug the water heater to a
socked. If the flexible cord is damaged, it must be substituted by an especial plug cord APARICI reference 91027.
Because the water heater has no components which would permanently separate it from the electric
network, upon the cable connection between it and permanent installation a switch must be installed which
breaks both power supply poles having between the open contacts a gap at least 3 mm wide.
