Sean,
I have been running a WaterMaid system on my 40,000 IG VL pool for 6 years with little to no trouble other then being a bit undersized. It is now time to start looking for a new cell or upgrade to a unit that will handle a pool of this size. I have three questions for you.

1. I found a ST-220 Autopilot Pool Pilot Soft Touch Power Supply that was factory refurbished. S/N#A402068R. Is there any way to tell if there is any warranty left on this unit and if not are there any concerns from buying a factory refurb unit?

2. If I run this unit with the DIG-60 (I would rather be a little big then border line again) at 3000 - 3500 ppm salt what kind of power consumption do you feel I will see. I normally run a 6 hr on 6 hr off cycle.

3. Do you think that a DIG-48 will be enough cell or should I stick to my first thought on the 60??
