Orientation of wet end.

Pump wet end can be oriented in 90 Degree increments, up, left or right as shown in illustration on the right. Pump will ship with discharge directed up. To change the discharge orientation, 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.  

Determine the pump plumbing size by measuring the outside diameter of the wet end male threads. Plumbing sizes for hot tubs are nominal, and not actual outside diameter (O.D.) of the the threaded intake or discharge. Once you have removed the pump,use a tape measure to check your old pump thread size and compare to the sizes below.
If your pump thread O.D. is (aprox.) 2 3/8",  Then you'll need a pump with union size 1 1/2".
If your pump thread O.D. is (aprox.) 3.0",     Then you'll need a Pump with union size 2.0".
If your pump thread O.D. is (aprox.) 3 5/8",  Then you'll need a Pump with union size 2 1/2".
Please note!
Some brands of hot tub spa pumps have non-standard threads and use fitting sizes with different dimensions. These brands are: Hayward, Jacuzzi and sta-rite.
