wired either 110-130vac or 220-240vac. So observe the label on the motor to wire
correctly. The sequence of wiring is the same for either an Emerson or an
AOSmith/Magnatek motor. White will be neutral and black hot.
Extra Help:
If you strip the bolts that hold the pump face (volute) to the pump housing
(bracket), you can easily buy a long bolt and nut locally and insert that through the
hole and tighten. You must tighten all four bolts to snug. If not, the pump will
eventually leak.
On some models the pump/motor is either behind another pump or even behind
the control box. There is no simple way to remove if you can do have access on
the side of the spa. In these cases, removing the pump/motor in front or in worst
case, the control box is easier.
See Specific Model suggestions found in later Chapters.
Circulation Pump:
On early Pinnacle you have either a smaller 110-130vac circulating pump or a
larger 220-240vac circulation pump. Replacement is easy for both. Usually you
will drain the spa. There isn't a shut off valve to replace the circ pump with water
still in the spa so you will have to drain it.
For the smaller pump, it's a 110-115vac Might Mite. Jacuzzi switched over to a
larger 220vac Aquaflo circulation pump for a short period. During this time many
Pinnacles were retrofitted with the Aquaflo pump. You may have to visually see
which brand pump you have. Also remember to check voltage.
Final productions used a black circulation pump that's located right in front when
you open the wood access.
Some supply houses sell the smaller replacement pump parts and motors.
Because of the constant service demands on this pump, it usually is wise to
replace the pump/motor complete. With the smaller circ pump, the replacement
