Important Information

  • WARNING: Risk of electric shock. Connect only to a properly grounded dedicated circuit protected by a Class A Ground-Fault Circuit-Interrupter (GFCI)*. Use 120 V, 60 Hz, 15 A service.
  • WARNING: Risk of electrical shock. To reduce the risk of electrical shock, route the 120 V power cord of the bath through a conduit separately from the solenoid and valve wiring conduits.
  • WARNING: Risk of electric shock. Disconnect the power before servicing.
  • CAUTION: Risk of personal injury. This bath is extremely heavy. Obtain sufficient help and use lifting straps to lift or move the bath.

NOTICE:
Grounding is required. The unit should be installed and grounded by a qualified service representative.

The bath must be connected only to a supply circuit that is protected by a Ground-Fault circuit interrupter (GFCI)*. Such a GFCI should be provided by the installer and should be tested on a routine basis. To test the GFCI, press the test button. The GFCI should interrupt power. Press the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the bath without the test button being pressed, a ground current is flowing, indicating the possibility of an electric shock. Do not use this bath. Disconnect the bath and have the problem corrected by a qualified service representative before using.

An equipment grounding terminal is provided in the field wiring compartment. To reduce the risk of electrical shock, this terminal must be connected to the grounding means provided in the electrical supply panel with a conductor equivalent in size to the circuit conductors supplying this equipment.

  • Install this unit per the Canadian Electric Code, Part I.
  • Outside North America, this may be known as a Residual Current Device (RCD).
  • Follow all local plumbing, building, and electrical codes.
  • To ensure a successful installation, install the bath on a level finished floor.
  • Provide access to plumbing and electrical connections around the bath for future maintenance.
  • This bath conforms to UL1795, CSA B45.5-171/IAPMO Z124-2017, ASME A112.19.7/ CSA B45.10-2012.
