Installation Guide

8. Make the Electrical Connections
NOTE: The product model number is printed on a label on the pump side of the whirlpool bath. This
label also identifies the electrical rating of the product. All whirlpools come equipped with a wiring
junction box and are designed to operate between 220 V and 240 V 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)*. This will provide additional protection
against line-to-ground shock hazard. A 220-240 V, 20 A, 50/60 Hz dedicated circuit is 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 stripe is the
equipment ground and needs to be connected to the neutral bus in the main circuit breaker box.
The whirlpool bath control and system have been pre-wired at the factory. A qualified electrician
should make a routine service connection to the junction box.
Connect service to the junction box. The junction box contains blue, brown, and green with a 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.
NOTE: Your wiring harness includes an antenna for the optional remote control. Do not alter or damage
this antenna during installation.
Bond in accordance with nation and local codes.
Open bonding lugs are located at the top of the
junction box.
