Hello, I have a 1998 Grandee Hot Sprints 8-person hot tub. I am looking to replace my heater. The heater I purchased nearly 2 years ago developed a crack in the plastic recently. I'm currently using a Watkins No-Fault 73790 6kw 240V PDR unit. It does not have a manual reset on it. I'm not sure if this hot tub could use a heater with a manual reset on it. Will this one work or should I order something else? And what's the warranty on something like this? Brian
Best Answer: I replaced a heater without a manual reset on it. The new one had one on it all the manual reset is, is a failsafe device in case the elements overheat or short out. If the elements never do either than you should never have to bother resetting it.
