Welcome to our forum.
Well we finally got to fill our new Caldera Niagra today. We had it delivered 3-months ago and have been in the process of building a 3-season room around it. I filled it this morning and turned the breakers on and all seemed well. The pumps went through there start-up sequence per the manual and the temp said 61 degrees (cold well water). Well 5-6 hours later the temp is only up to 68 degrees and the water coming out of the circulation pump is cold, not warm. I pulled off the front panels and felt the pipe coming out of the heater and it was pretty cool. I put my meter across the white & black wires that go to the heater and was reading 120 volts.....shouldn't this be 240 volts??? Should I call my dealer or my electrician? Thanks for any & all advice.
Yup. The dealer gave you the wrong box. That one is for a convertable HotSpring spa.
