- WARNING – Risk of Electrical Shock – Do not permit any electrical appliances (such as a light, telephone, radio, or television) within five feet of the bathtub.
- DANGER – To reduce the risk of injury, do not remove the suction cover from the bathtub.
- To Reduce the Risk of Injury:
- A. The water in your bathtub should not exceed 104°Fahrenheit. Lower water temperatures are recommended for extended bathing (exceeding 10-15 minutes) and are definitely recommended for young children.
- B. Pregnant or possibly pregnant women should consult a physician before using the hydro massage bathtub. Water temperatures in excess of 100º Fahrenheit are not recommended.
- C. The use of alcohol, drugs or medication before or during the use of the hydro massage bathtub may lead to unconsciousness with the possibility of drowning. Consult your physician before using the bathtub if you are using medication.
- D. Persons sufering from obesity or with a medical history of heart disease, low or high blood pressure, circulatory system problems or diabetes should consult a physician before using the hydro massage bathtub.
- WARNING – Risk of Child Drowning – To reduce the risk of accidental drowning, do not permit children to use the hydro massage bathtub unless closely supervised.
- WARNING – RISK OF ELECTRICAL SHOCK -All electrical connections must be accomplished by a qualified electrician in accordance with Article 680 of the National Electric Code and any local codes. In addition, a GFCI MUST protect all branch circuits to the bathtub and every electrical component MUST be grounded.
INSTALLATION
Warning: When using electrical products, basic precautions should always be followed, including the following:
- DANGER – RISK OF ELECTRICAL SHOCK -Connect only to a circuit protected by a Ground-Fault-Circuit-Interrupter.
- Grounding is required. The heater should be installed by a qualified technician and grounded.
- Install to permit access for servicing.
ELECTRICAL CONNECTION
Install a separate 120 VoIt 15/20 Amp dedicated circuit with GFCI (Ground
¬Fault-Circuit-Interruptor) protection. With a No.8 solid copper wire, bond
the heater and hydro massage bathtub pump to the homes electrical panel or
approved local bonding point. A bonding lug has been provided on the heater.
First you must locate the pump and Heater Ready fitting supplied with your
hydro massage bathtub.
Note: Photos are for illustration purposes only. The Heater Ready fitting
in your particular application may be located anywhere in the plumbing
mentioned.
- Route two separate branch circuits (see illustration below) to the junction box near the bathtub. *Each branch circuit MUST BE GFCI PROTECTED.
- Use solid copper conductors only.
- Insure the heater and pump are properly GROUND-ED and BONDED as required. A bonding lug suitable for No.8 AWG wire has been provided on the heater (most pumps provided with the hydro massage bathtub will also include a bonding lug). A Heater Ready fitting has been supplied by the bathtub manufacturer to allow for ease of heater installation. (Photo #1)
SEPARATE GFCI PROTECTED CIRCUITS
- Carefully loosen Heater Ready fitting nuts and remove the Heater Ready fitting ensuring that ridged gaskets stay in place as shown in Photo #2.
- Making sure that gaskets remain installed on the existing threaded tailpiece fittings, insert the heater into place as shown in Photo #3. (Heater may be positioned in any direction, i.e. up/down)
- Once the heater is in place, inspect heater and gaskets for proper alignment. Tighten heater union nuts to insure a proper seal. Photo #4 shows a typical completed heater installation.

- WATER LEAKS FROM CONTROL BOX
- Defective Component
- Replace Heater
- GFCI TRIPS OCCASIONALLY Lightning or Electrical Storm, Power Surge, Extremely Humid Conditions or Radio Frequency
- Interference – Reset GFCI Note: Assure Heater is properly Grounded and Bonded Inspect Heater for Leaks or Moisture – Correct or Replace as Required
- GFCI TRIPS REPEATEDLY Defective Component – Replace Heater
- CIRCUIT BREAKER TRIPS
- Breaker Size Improper
- Contact a qualified service technician. Heater Requires a DEDICATED Circuit -Assure No Other Appliances are on this Circuit
- Now that the heater installation is complete, fill the bathtub with water (preferably cold so the heater can be properly tested below lOOº F).
- Inspect all plumbing connections for leaks.
- Activate the hydromassage pump to circulate water throughout the plumbing of the system and check again for leaks at all plumbing connections.
- Turn off the pump and plug the heaters power cord into the 20Amp GFCI-protected outlet.
- Activate the pump and verify that the Heater ON indicator light is illuminated on the heater. When illuminated, the heater is operating properly and will continue to do so as long as there is water flowing through the plumbing to maintain and prolong your bathing enjoyment.
OPERATION
Once the Whirlpool Bath Heater has been installed, the operation is totally automatic. The Heater will help maintain the temperature of the water in the bathtub or increase the temperature of the water in the bathtub at about two to four degrees Fahrenheit per hour. The heater includes the following components:
- THERMOSTAT: The Smart Thermostat requires no adjustment and will automatically maintain the water temperature at lO2º F-lO4º F. If the bathtub water is too warm, simply adjust by adding cold water. See important Safety Instructions.
- HIGH-LIMIT: The heater includes an exclusive intelligent High-Limit circuit that constantly monitors the water temperature and assures that any overheat condition turns off the heater until the condition has been corrected. This safety circuit will not trip from hot tap water. It will only turn off if the thermostat fails. To manually reset the circuit in the event that the High-Limit switch has been activated, simply (I) Turn off the whirlpool Pump (2) Drain water from the tub (3) Remove power from heater by unplugging at receptacle or turning off circuit breaker (4) The heater circuit will automatically reset in less than 15 minutes (5) Restore power to heater (6) Whirlpool Bath is now ready for use. lf the high-limit trips frequently, contact your local dealer or service company.
INDICATOR LIGHT
The light turns on when the heater is operating.
PRESSURE/VACUUM SWITCH: The heater is equipped with a preset pressure or vacuum switch. The pump must be running with water flowing in the whirlpool to allow the heater to turn on. Note: Smaller fractional horsepower pumps may not activate the heater. Contact your dealer for a troubleshooting procedure.
- The heater must be connected only to a supply circuit that is protected by a ground-fault-circuit-in-terrupter (GFCI). The GFCI should be tested on a routine basis. To test the GFCI, push the test button. Power to the bathtub should be turned off. Push 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 bathtub without the test button being pushed; a ground current is flowing, indicating the possibility of an electrical shock. Do not use the bathtub. Disconnect the hydro massage bathtub and have the problem corrected by a qualified service technician before using.
- WARNING – Prolonged immersion in hotter water may induce hyperthermia. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body temperature of 98.6°F. The symptoms of hyperthermia include an increase in the internal temperature of the body, dizziness, lethargy, drowsiness and fainting. The effects of hyperthermia include:
- A. Failure to perceive heat
- B. Failure to recognize the need to exit the bathtub
- C. Unawareness of impending hazard
- D. Fetal damage in pregnant women
- E. Physical inability to exit the bathtub
