8. Make the Electrical Connections
NOTE: The product model number is printed on a label on the pump side of the unit. This label also
identifies the electrical rating of the product.
WARNING: Risk of electrical shock.Make sure the power has been disconnected before performing
the following procedures. Refer to IMPORTANT INFORMATION section.
CAUTION: Risk of electrical shock. All services must have a Class A Ground-Fault Circuit-Interrupter
(GFCI) which will provide additional protection against line-to-ground shock hazard. A dedicated
service is required for the overflowing bath.
The overflowing bath control and system have been prewired at the factory using 220V hardwire. A
licensed electrician should make a routine service connection to the junction box located on the control
box.
Connect service to the junction box. The junction box contains black and green wires. The grounding
conductor must not be connected to any current-carrying conductor.
Follow local electrical codes.
9. Test Run the Bath
Check the Connections and Fill the Unit
NOTE: The system will purge air at start-up. This is normal.
Check all electrical connections, and make sure the electrical power to the unit is turned on.
Make sure union connections to the pump and in-line heater are securely handtightened.
Make sure the bathing well and overflow channel are clean and free of debris.
Fill the bath as you would a normal bath, 4” (10.2cm) – 6” (15.2cm) from the top, to allow for water
displacement when you enter the bathing well. Water entering the overflow channel will flow into the
drain.
Test the Control Switch
Press the ″On/Off″ control switch to start the pump/motor and begin the hydro-therapy cycle. A green
light in the ″On/Off″ control switch will turn on to indicate the start of the operating mode. As the
pump/motor turns on and water begins to circulate, the light remain green while the unit is running.
With the unit running, check all harness (piping) connections for leaks.
Visually observe the effervescence rising to the surface of the water.
