Frames" refers to the size of your pump. All main spa pumps have either 48 or 56 frames. 48 frame pumps motors are 5.5" in diameter. 56 frame pump motors are typically 6.5" in diameter. You can also determine the frame size from the bolt spacing- the 48 frame is 3-5/8" and the 56 frame is 4-1/4."

Motor voltage, not the voltage supplied to the spa to determine the correct pump voltage. There will be a plate on the motor the should indicate Horse Power. Also if one or two speed.(3450/1725 rpm) You can wire a two speed to work at one speed.

When removing the power cord from existing pump we recommend you mark your wires for "common", "High speed", "low speed". The connection diagram for the new pump is located on the motor nameplate.

Most wirings of motors are simple.

NOTE: Sometimes the Red wire is used as HIGH. To fix just reverse BLACK and RED on MOTOR.

Be sure of the GROUND and " White " COMMON wire placement. The breaker will POP.

They have a { Top to Bottom/ Left to right } numbering ( G, C, H, L ) ( L1,L2, L3, L4 ), etc.
Green is "G" "L1" Ground -
White is "C " "L2" Common -
Black is "H" "L3" High Speed and RED is "L" "L4" Low speed.

If when you turn it on you get HIGH speed - reverse the Black and Red wires.

If wiring ONE SPEED it would be Green - White and Black.

If you are unsure as to whether the pump will work for you, call us and we can discuss it with you.

Spa pumps come in many different shapes and sizes.Follow these steps to Choosing the Right Spa Pump and you’ll be on your way to becoming a spa pump expert. There are 4 criteria you should take notice of when purchasing a spa pump:

1) Horsepower (motor) – The horsepower on your spa pump motor will determine the action in your jets. The more horsepower you got in your motor, the more force you’ll be feeling when relaxing in your spa. But before buying the spa pump motor with the highest horsepower you should consider if your control and electrical system can handle the new increased amount of power the new spa motor will draw.

When upgrading your motor to a higher horsepower, try not to increase your power by more than 1. It’s a good idea to go from 1 HP to 2 HP, but not a good idea to go from 1 HP to 5 HP.

2) Spa Pump Speed (motor) – Most spa pumps come with 2 speeds, allowing you to adjust the spas amount of water being shot at you. We offer you both 1 speed and 2-speed pump motors for your spas.

3) Voltage (motor) – Take your pick at a 115V or 230V spa pump motor; they only come with these two voltage options. Actually, the determinant of this will be the electrical outlet where you will be hooking up your spa. Determine your outlet voltage and choose the corresponding spa pump motor voltage.

4) Center or Side Discharge (pump) – When choosing spa pumps you must consider whether it is a center discharge or side discharge. Your spa pump that you intend on replacing will look like one of the following. Take notice of the position of the discharge component of the wet end. Purchase your new spa pump accordingly. The left is a side discharge. The right is a center discharge.

5) Frame Size (Motor) – When choosing a spa pump you must consider whether it is 48 or 56 frame. Frames" refers to the size of your Motor. All main spa motors have either 48 or 56 frames. 48 frame motors are 5.5" in diameter. 56 frame pump motors are typically 6.5" in diameter. You can also determine the frame size from the bolt spacing- the 48 frame is 3-5/8" and the 56 frame is 4-1/4." This will make a difference in how easily the pump matches the current spa plumbing connections.
