HD- SYSTEM OPERATING MANUAL Revision: 1/26/2018
N. This unit must be connected to a circuit that is protected by a Ground Fault Circuit Interrupter
(GFCI). The GFCI should be provided and installed by a licensed electrician and tested on a
regular basis (at least monthly). To test the GFCI push the TEST button. The GFCI should
interrupt the power. Push the RESET button and the power should be restored.
If the GFCI fails to operate in this manner there is a possibility of an electric shock. DO NOT
OPERATE THIS UNIT. Disconnect the unit and have the problem corrected by a licensed
electrician before using.
If you become nauseous, dizzy or develop a headache you may be
experiencing Hyperthermia, an unsafe increase in your core body temperature.
Get out at once and cool down. Get medical attention if symptoms persist.
Check with a physician before using the bathtub again.
L. A thermostatic mixing valve is required, and must be provided by the installer. Section 414.5
o f the 2009 Uniform Plumbing Codes require that the maximum hot water temperature discharging
from the bathtub and/or whirlpool bathtub shall be limited to 120°F (49°C) by a device that
conforms to ASSE 1070 or CSA B125.3. The water heater thermostat shall not be considered a
control for meeting this provision.
LI. The water in a walk-in tub should never exceed 40°C (104°F). Water temperatures between 38°C
(100°F) and 40°C (104°F) are considered safe for a healthy adult. Use time should be limited to
approximately 15 minutes, followed by a shower to cool down. Lower water temperatures are
recommended for extended use (exceeding 10-15 minutes) and are recommended for younger
children, the elderly and frail.
