Caleffi Pressure Reducer with Gauge

This product is to be used with our Elgena NC6-E 12 Volt water boiler. This allows you to adjust the pressure coming from the water pump and into the water boiler. You just have to dial the gauge down to 2 bars (it comes with instructions). IF you choose to use a pump that outputs more water than 2 bar (limited to 6 bar) it's mandatory to use the Pressure Reducer to not void warranty.

Made in Italy.



Elgena Nautic Boilers are designed to withstand max. 3 bar (43.5 psi) of water pressure. 
Most water pumps in North America generate a lot more! Therefore it is VERY important
To install a pressure reducer. 
We recommend a pressure below 2 bar (29 psi).
  • WITHOUT heating the water, turn on the tap. Follow the arrow on the adjuster knob and dial down to 2 bar (29 psi). 
  • Best if the tap is turned on and off several times during this process. Adjust till the system reaches 2 bar (29 psi) MAX!
Failing to follow these instructions could cause serious burns and water damage to yourself and vehicle.
