Hey Folks,

I have an older Sundance spa (silverado I think) circa 1980. I am in the process of replacing the heater element. I bought a heater and box from you folks (P/N 157 876570 003) but have a question.

My system is set up for 240V. My previous heater conected by 2 black wires to the control panel (it is a sentry unit, but I forget the model #). The new heater has 3 wires; the ground (green), the hot (black) and the neutral (white). I opened up the box to see if there was more info on hook up, but no real help, although it looked like the neutral could be used either way.

Bottom line is, when I hook it to the sentry control, do I hook the black and neutral to where the 2 black leads went? If so, does it matter to which one it is connected? Normally, I would guess that the 2 black leads might be hot, as most 240V systems have red and black, or black and black wires for hot, so I am a bit concerned. I appreciate any assistance you can give.

Thanks in advance for your help!

Yeah it does not matter which goes to which on that AC circuit. Two current carrying wires coming from the element - connect to two current carrying wires from the controller. The heater manufacturers like to be "compliant" to make folks ask a lotta questions. It actually may be required by some strange gift of industry certification or something to make the wires black and white. But yet, they don't paint the ends of lead-less heater elements black and white do they?

And of course, green is ground.

HELP!,

I recently obtained an old (83) ramco/gerico hot tub and have refurbished it. Lots of time invested framing, wiring, plumbing. Unfortunatly, the wiring to the original control panel was destroyed, and i have replaced it. Now, i know that gerico/ramco made the things in their garage and there are probobly no schematics out there but this is sent in the hope that you may have one or someone/something out there to help me out.

The machine pumps fine (lo and hi), the hi-limit switch and the pressure switch work as advertised (after a rebuild of each), hi-pump works via its switch, and so does the light. the wiring to/from the relays (inside the box) are all in order. The thermostat seems to work (it clicks, and does recognize temp differences), the heater gets 120 v when requested from the control box (no heat, however),
but i am not able to figure out the reason/operation of the green wire from the circuit card to the
contol panel. The unit does not heat but the coil looks good and reads at 10 ohms. I think mebe the green wire makes a secondary contact in the l/h spd pump relays for the heater coil, when the heater is off i see 120v at each terminal, when the ls pump is on, i see it on only 1 side.

I have a 6 pin connector on the circuit card (from left to right top to bottom it reads;
1-red gnd 0v, 2-unused0v, 3-whi light 3v, 4-green 3v dunno, 5 black hs pump3v, 6-blu 3v ls pump/ heater?

I hope that this makes sense to you, if not, I can and will refine it. The heater did work about a year ago, but the wiring to the topside control panel got tore up somehow before i purchased it.

Appreciate your time and effort.

thanks,
