WATER SUPPLY CONNECTION
Connect the water heater intake and outlet with pipes or accessories that are able to withstand temperatures
over 100ºC at a pressure that exceeds working pressure (8 bar). Therefore, we strongly recommend that no
materials should be used that cannot withstand high temperatures.
When fitting the water pipes follow the basic rules to prevent corrosion: “Do not use copper before iron or steel
in the direction of the water flow”. To prevent galvanic pairs and their destructive effect, use Teflon tape to
thread the insulating hoses supplied with the heater to its two pipes.
Thread the cold-water intake pipe (blue) to the electrolytic hose and from this to the hydraulic safety sub-
assembly with the draining device supplied with the heater. Fit a cut-off valve to the cold-water supply pipe.
IMPORTANT: the cut-off valve must always be in the open position whenever the heater is switched on,
Some countries require alternative safety devices to be used and there may other requirements under local
regulations: the installer must check the suitability of the safety device that he or she tends to use. Do not fit
cut-off device (valve, tap, etc.) between the safety unit and the heater itself.
Connect the hot water distribution pipe to the hot water outlet pipe insulating hose (red) from the heater.
The hydraulic safety valve or assembly supplied with the water heater is fitted with a retention and overpres-
sure valve. The latter opens to a maximum of 8 bars. If the pressure in the water installation exceeds 5 bars,
fit a pressure reducer, as per regulations.
