Found in these spas: LA Spas, Artesian, Atera, Hydro Quip, Santa Barbara.

PLEASE NOTE: If using this replacement for a C3236-1A in an older Artesian Spa. This new heater will not fit around the spa pack and must be REMOTE MOUNTED.

There will be discrepancies between the new and old unit.   This new heater will have 3 wires, not 2.  Black and White go to the circuit board, and Green goes with the ground wires.

Also, the water connections will not be the same size. Any kind of reducer, such as a small piece of clear pipe set around the smaller connection will correct this.  You would then slip the larger connection over it.
