All pumps are not provided with unions, unions sold separately. Unions are identified by plumbing dimensions (like 1.5" or 2.0"), but these numbers ARE NOT the physical outer pipe dimensions. These numbers indicate the waterflow volume going into and out of the pump. Please use part numbers as identified for your application.
All electrical work must be performed by a licensed electrician.
All plumbing work must meet I.A.P.M.O., UL 1563, and all local codes and regulations and must be performed by a licensed plumbing contractor.
Most portable spas and hot tubs are equipped with thru bolt motors, 48-Frame or 56-Frame. When looking for a replacement spa pump motor follow these steps:
(1) Look for the label provided by the original electric motor manufacturer Manufacturers include "Century", "Magnetek", "A.O.Smith", "Regal Beloit", "Emerson", "Franklin Electric", "GE", "Centurion", "SNTech", "Dynatech".
(2) Identify the voltage required (115 volts or 230 volts), "high" and "low" speeds (spa pump motors are typically 3450 RPM high speed and 1725 RPM low speed). Single speed motors are "high" speed (3450 RPM). Circulating pump motors are "low" speed (1750 RPM).
(3) Identify the amperage and ALWAYS choose a replacement motor with the same or higher amperage on high speed.
NOTE: All the motors are identified by original motor manufacturer catalogue number. Catalogue numbers are issued by the motor companies to be used by distributors. Motor manufacturers also assign EMI numbers (also known as part numbers) to pump manufacturers to distinguish between distributors and pump manufacturers, however all motors are the same.
