8. Make the Electrical Connections
NOTE: The product model number is printed on a label on the pump side of the overflowing bath. This
label also identifies the electrical rating of the product. These whirlpools come equipped with two wiring
junction boxes and are designed to operate between 208 VAC and 240 VAC at either 50 Hz or 60 Hz.
WARNING: Risk of electrical shock. Make sure the power has been disconnected before
performing the following procedures. Refer to the “Important Information” section.
WARNING: Risk of electrical shock. To reduce the risk of electrical shock, connect the pump to a
properly grounded Ground-Fault Circuit-Interrupter (GFCI)*. The heater will also need to be
connected to a properly grounded Ground-Fault Circuit-Interrupter (GFCI). This will provide
additional protection against line-to-ground shock hazard. Two 208-240 V, 20 A, 50/60 Hz dedicated
circuits are required.
IMPORTANT! The load neutral is not used. There should be no connection to the load neutral terminal
on the Ground-Fault Circuit-Interrupter (GFCI) breaker. The green wire with the yellow stripes is the
equipment ground and needs to be connected to the neutral bus in the main circuit breaker box.
The control and heater have been pre-wired at the factory. A qualified electrician should make
routine service connections to each of the junction boxes.
Connect service to the junction boxes. Both junction boxes contain blue, brown, and green with
yellow stripe colored wires.
Follow local electrical codes. Bond in accordance with national and local codes.
A wiring harness has been pre-wired at the factory, allowing communication between the keypad,
all features, and the control. No additional wiring is required, but ensure that all wires are securely
fastened.
Bond in accordance with nation and local codes.
Open bonding lugs are located at the top of the
junction box.
