This heater unit replaces the Watkins no-fault heater units on spas produced After 2002. The sensors have the correct connectors for the newer IQ 20/20 Spa Pack.
We highly recommend having this heater installed by a hot tub engineer, if you skill set is not up to making alterations to plumbing.
A minor plumbing change will need to done in order to use this replacement system to re-route the 0.75" feed and return pipe work from the old heater to the new.
Supplied with unions.
