About Frame size

Side vs. Center Discharge

Orientation of Wet End

Pump wet ends can be oriented in 90º increments to meet your installation requirements. Loosen the pump's four through bolts from the back of the motor and pull them back enough to disengage. Then rotate the wet end to the desired position, realign and re-tighten the bolts.  

Wet ends can be rotated

How to Determine Spa Pump Plumbing Size
by measuring O.D. of wet end male threads

Plumbing size

Pump plumbing sizes are nominal, and not actual outside diameter (OD) of the threaded intake or discharge. Use a tape measure and check your old pump thread size against this sizing table for most* spa pump brands:

4 HP Spa Pump: 2" in/out, Side Discharge, 56 Frame-240V
Instalation almost went flawlessly. I wired motor according to the 10 yeear old motor I was replacing. Fuse blew. Rewired according to new motor and replaced fuse. Works like a charm and its whisper quiet.
