N-Series pump cable connection (R1071)


N-Series pump cable connection (R1071)

The N-Series water heaters have the ability to control a circulation pump, in a ring main application, with the use of the pump cable connector (UV resistant and rated for outdoor installation). This allows hot water to cycle through the ring main, ensuring hot water is quickly available when a tap is opened.

Suitable for
N56 water heaters in the following applications:

  • Single unit N56 domestic installations*
  • Commercial / showerblock installations with multiple N56 units, as specified by Rinnai commercial

Please note
Rinnai INFINITY digital controllers are not compatible with the N-Series pump cable and ring main applications.


* When multiple N56 units are connected together small but noticeable water temperature fluctuations may occur as the load increases and additional units ignite. This is normal operation and not a system fault (warranty). For this reason care should be taken when specifying multiple N56 units in ring main applications where discerning customers may be dissatisfied with minor temperature fluctuations. In these applications please refer to Rinnai commercial for alternative hydraulic arrangements that will be manage these fluctuations—DO NOT use the pump cable.
