INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRICAL SHOCK OR INJURY TO
PERSON
WARNING - When using this unit, basic precautions should always be followed, including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS
2. The heater 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, push the test button. The GFCI should interupt power. Push the reset button.
The Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the
GFCI interrupts power to the heater without the test button being pushed, a ground current is flowing,
indicating the possibility of an electrical shock. Do not use this hydromassage bathtub. Disconnect this
hydromassage bathtub and have the problem corrected by a qualified service representative before
using.
3. SAVE THESE INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
Prolonged immersion in hot water may induce hyperthermia. Causes, symptoms, and effects of
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, and
F) Unconsciousness resulting in the danger of drowning.
WARNING - The use of alcohol, drugs, or medication can greatly increase the risk of fatal
hyperthermia.

If your hydromassage bathtub has been equipped at the factory with a Heater Ready fitting, installing
your Whirlpool heater is a snap. (See figures 2 & 3 below for common heater location.) Note: these

CLEARANCE:
Your Whirlpool heater has been specifically designed
to be compact and easy to install. In most cases
there will be no interference installing your
hydromassage bathtub with the addition of a Pure
Heat heater. Prior to installing your heater, consult
manufacturers instructions regarding bathtub
installation clearance requirements.
If your hydromassage bathtub did not come equipped with a Heater Ready fitting you will need to install
your Whirlpool heater onto the bathtubs jet pump, cutting away excess plumbing and installing the
tailpieces included. Be sure the location will be accessible if a need for service should arise. (See figure 4
below for common heater location.)

2 - Loosen nuts (3) and remove Heater Ready fitting and existing gaskets.
3 - Remove two (2) heater gaskets included with your Whirlpool heater and install them onto the
plumbing tailpieces, making sure the gasket ridge is seated in the tailpiece groove (see Fig. 7).
Remove one (1) union gasket and install at pump discharge.

4 - You are now ready to install the heater in the open space where the Heater Ready fitting was located
(ensure that the gaskets remain in place). Slide heater nuts inward toward the center of the heater to
expose the mating surfaces of the heater housing. Slide the heater carefully into place between the
tailpieces and gaskets, pump and union gasket and hand-tighten heater nuts. If you use a wrench be
careful not to over-tighten, the nuts can crack.

1 - Power to the hydromassage bathtub must be turned OFF and all water must be drained
from the bathtub before proceeding.
2 - Locate the hydromassage jet pump in the plumbing in the system.
3 - For convenience, a template has been provided on the back page of this instruction booklet. Simply
detach, position against plumbing and mark according to plumbing size.
4 - Using a hacksaw, PVC cutter or a cable saw, cut the pipe at the marks made. If using a cable saw,
carefully line the saw blade up with the marks that were made in the previous step and begin cutting
using an alternating pulling/releasing motion (see Fig. 10). Once both cuts have been successfully
made, loosen and discard PVC “T” fitting and detached portion of plumbing.

5 - De-burr the plumbing, clean outer surface of plumbing and prepare the surfaces for gluing.
6 - Your Whirlpool heater includes three (3) sets of tailpieces to adapt the heater to virtually any
hydromassage bathtubs plumbing system. Dry fit the tail pieces to determine which tailpieces adapt
properly to your plumbing and discard the tailpieces that do not fit.
Note: Let the saw blade do the
work, do not put excess pressure
on the plumbing. Have someone
else stabilize the plumbing while
you cut if needed.

7 - You are now ready to install the tailpieces onto the bathtub plumbing. Apply PVC glue to one end
of the plumbing. Spread glue evenly over a 1-1/4” area from the end of the cut. Quickly apply
glue to the inside socket of the tailpiece. Before the glue dries, slide the tailpiece onto the
plumbing with a slight twisting motion assuring it has reached the stop built into the tailpiece and
hold for 15-seconds to allow the glue to setup. Wipe away any excess glue and repeat the gluing
process on the second tailpiece. Once the glue has set, you should have approximately 7”
opening for part numbers SG100-15UP & SG202-20UP (see Fig. 11) in order to install your
Whirlpool heater.

ELECTRICAL REQUIREMENTS
DEDICATED CIRCUIT INSTALLATION
A qualified and licensed electrician in accordance with the National Electric Code (NEC) Article 680,
Canadian Electric Code, and with any local codes must accomplish the electrical installation.
All connections must be made according to the electrical installation label on the outside of the control
box. Follow the instructions from the label if they are different than the instructions in this manual. If your
electrician is not absolutely sure how to connect your system correctly, call your local dealer. Any mistake
may be costly and void your equipment warranty.
The GFCI (Ground Fault Circuit Interrupter) is a mandatory electrical safety device required for all
hydromassage bathtubs as specified in the National Electrical Code Article 680-70.
Your bath equipment may require a DEDICATED CIRCUIT. This means no other appliances or lights
can be on this circuit. Refer to equipment data label for power supply requirements of your bath
heater.
Use copper conductors ONLY. The ground must be sized following the National Electric Code, Table
250-122.
For Power conductor size, refer to the National Electric Code Table 310-16.

1 - Prior to testing your installation for leaks, you must properly bond the Whirlpool Bath Heater to the
bonding system of your hydromassage bathtub. All Whirlpool Bath Heaters come equipped with a
bonding lug and 8AWG bonding wire specifically for this purpose. Refer to bathtub manufacturers
instructions to locate the bonding system. All electrical wiring and bonding must be done as specified
in Article 680, National Electric Code and your local Building Code.

SINGLE CIRCUIT INSTALLATION**
In certain cases you may be able to plug the heater and the pump into the same single circuit outlet.
This generally requires that one or both of the components have a very low amperage rating. See the

8 - After allowing the glue joints to dry, a STATIC leak test must be accomplished. You can
accomplish this by SLOWLY filling the tub with COLD WATER until the water level is at least 2”
above the highest jet.
IMPROPER INSTALLATION OF THE PURE HEAT HEATER CAN RESULT IN WATER
LEAKING FROM THE PLUMBING SYSTEM! WATER DAMAGE CAN OCCUR TO SPACES
BELOW OR ADJACENT TO THE HYDROMASSAGE BATHTUB.
Do not leave the tub unattended during the testing process and only fill the tub with enough
water to exceed the level of the hydromassage jets.
FILL THE TUB SLOWLY SO FILLING CAN BE STOPPED IF A LEAK IS DETECTED. DRAIN
THE TUB IMMEDIATELY IF A LEAK IS DETECTED AND CORRECT THE PROBLEM
BEFORE RETESTING.
9 - If there were no leaks detected, a PRESSURE leak test must be accomplished. Perform this final
REQUIRED leak test by activating the hydromassage jet pump. Allow the system to run for 15-
20 minutes minimum. The cold water will allow you to verify that the “Heater On” indicator is
illuminated on your Whirlpool heater. If the light does not illuminate or if you encounter any other
problems, refer to the Troubleshooting section of these instructions.
IF NO LEAKS WERE DETECTED AND YOU HAVE VERIFIED THAT
YOUR PURE HEAT HEATER IS FUNCTIONING PROPERLY,
CONGRATULATIONS, THE INSTALLATION OF YOUR PURE HEAT
HEATER IS COMPLETE. YOU CAN NOW RELAX AND ENJOY THE
COMFORT YOU WILL EXPERIENCE IN YOUR HEATED
HYDROMASSAGE BATHTUB.
