INSTALLATION INSTRUCTIONS
Safe-T-Heater™ Whirlpool Heater
Models: 9075.120
Your Safe-T-Heater whirlpool bathtub heater has been specifically designed to
enhance the enjoyment of your whirlpool bath. Once filled, the temperature of
the whirlpool bath is constantly maintained by a built-in thermostat for as long
as you desire.
Your Safe-T-Heater whirlpool bathtub heater is totally self contained to ensure
trouble free installation and operation. As with all electrical devices, certain
safety precautions should be taken during installation and operation. Please
read and follow all instructions carefully.
IMPORTANT SAFETY INSTRUCTIONS
INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS – READ AND FOLLOW ALL INSTRUCTIONS
You should have received safety instructions with your whirlpool bathtub system. Please read and follow them carefully. Those instructions will
include the following warnings:
1. WARNING – Risk of Electrical Shock – Do not permit any electrical appliances (such as a light, telephone, radio, or television) within five
feet of the whirlpool bathtub.
2. DANGER – To reduce the risk of injury, do not remove the suction cover from the whirlpool bathtub.
3. To Reduce the Risk of Injury:
a. The water in your whirlpool should not exceed 104° Fahrenheit. Lower water temperatures are recommended for extended use
(exceeding 10-15 minutes) and are definitely recommended for younger children.
b. Pregnant or possibly pregnant women should consult a physician before using the whirlpool. Water temperatures in excess of 100°
Fahrenheit are not recommended.
c. The use of alcohol, drugs or medication before or during the use of the whirlpool may lead to unconsciousness with the possibility
of drowning. Consult your physician before using the whirlpool if you are using any medication.
d. Persons suffering 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 whirlpool.
4. WARNING – Risk of Child Drowning – To reduce the risk of accidental drowning, do not permit children to use the whirlpool unless they are
closely supervised.
5. 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
whirlpool, and every electrical component MUST be grounded.
6. The unit must be connected only to a supply circuit that is protected by a ground-fault circuit-interrupter (GFCI). Such as GFCI should be
provided by the installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt power.
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 electric shock. Do not
use this bathtub. Disconnect the hydromassge bathtub and have the problem corrected by a qualified service representative before using.
7. 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 effect 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

OPERATION
WARNING: Prior to operation, review the Important Safety
Instructions listed at the beginning of this instruction manual.
Once the heater is installed and the whirlpool pump is operating, the
heater is totally automatic. The heater will help maintain the temperature
of the water in the bath.
Pressure Switch
The heater is equipped with a preset pressure switch. The pump must be
running with water flowing in the whirlpool to allow the heater to turn on.
Indicator Light
This light turns on whenever the heater is operating (Fig. 1).
High-Limit Switch
To manually reset the circuit in the event that the “High-Limit” switch has been activated, simply (1) 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 the heater (6) Whirlpool bath is now ready to use.

ELECTRICAL CONNECTIONS
Install a separate 120VAC / 15AMP dedicated circuit with GFCI (Ground Fault Circuit Interrupter) protection.
At initial start-up with power ON, push the GFCI test button. The reset button should pop out. Push this button in to reset. If the GFCI fails to
operate in this manner, there is a ground fault or malfunction, indicating the possibility of electrical shock. Turn off the power and do not
use the bath until the source of the problem has been identified and corrected.
1. Route two separate branch circuits to the junction box near the whirlpool as shown in Figure 2. Each branch circuit MUST BE GFCI
PROTECTED and must use copper conductors only.
2. Ensure the heater and pump are properly GROUNDED and BONDED as required. Attach the 8 AWG solid copper conductor supplied with
the heater from the heater bonding lug to the motor frame bonding lug as shown in Figure 3. The conductor is secured to the lugs using set
screws. The motor frame shall have a second 8 AWG solid copper conductor connected from the frame bonding lug to the homes electrical
panel or approved local bonding point as shown in Figure 3.
