Sparky:

From your post:

"Use ground fault circuit interrupters (GFCI) for the power supply circuit for each piece of electrical equipment, including utility pumps to drain the pool water. The GFCI will disconnect the power supply if any electricity leaks are detected."

110.3 (b) follow mfg instructions.....guess there's a 'leak' in the thing somewhere.
Warranty issue with the pool guy? Seriously, it could be a bad unit.
