Although this was a direct replacement for my existing heater when I connected the pressure switch cable it would not work. Possible a pressure switch problem.

Do Hot Tubs Need Chemicals

Hot Tub Water: Why Does it Need “Chemical Treatment?”

In the case of a bath tub, you just fill it with water to the warmth you want, take your bath and then let the water drain out. Typically, you don’t bother to treat the water in any way. In the case of hot tubs, however, you have to take the trouble of treating the water with different chemicals. Why this difference?

A hot tub typically accommodates more than one person at a time. It is more a place to relax for longer periods rather than just take a quick bath. Often, it is used for therapeutic purposes, to get relief from aches and pains through a hot soak and a therapeutic massage provided by the jets built into the hot tub.
