REDHEAD®
UL LISTED HYDROMASSAGE BATHTUB WATER
TEMPERATURE MAINTENANCE HEATER INSTALLATION INSTRUCTIONS - HEATER REDDY FITTING
PRESENT
INSTALLATION
OVERVIEW
Your
bathtub manufacturer has provided a simple method of installing a UL Listed
Redhead bathtub water temperature
maintenance heater into the piping system of your jetted hydrotherapy tub by
factory installation of a UL Recognized component Heater Reddy™
fitting in your hydrotherapy bathtub’s plumbing system. The Heater
Reddy fitting ensures that you will
be able to correctly install your Redhead heater in the field so that it will be
leak-free after the installation is complete and is installed without
compromising the hydraulics engineered into your hydrotherapy bath by your
manufacturer.
To
install the Redhead heater in the plumbing system of the hydrotherapy bath, the
installer will first be required to perform a simple task of making two cuts
through the plastic `Heater Reddy fitting with a wire saw provided with your
Redhead heater. Once you have successfully cut through the Heater Reddy
fitting, you will be able to install your Redhead heater by following
these instructions and by doing so, you can be assured that a proper
installation will be achieved (even by folks that do not consider themselves to
be “handy”). A wire saw provided with the Redhead heater will be the only
special tool you will need to install your Redhead heater. Follow the
instructions below EXACTLY and IN
THE ORDER LISTED. Once installed, your Redhead heater will provide
years of successful operation in maintaining the water temperature of your
hydrotherapy bath as you wish.
STEP-BY-STEP
INSTALLATION
Step
1 -
Disconnect
all electrical power connected to the bathtub hydrotherapy system and drain
all water from the bathtub and hydrotherapy jet system piping before
starting the heater installation.
Step
2 -
Locate
the red plastic Heater Reddy fitting
in the plumbing system of the hydrotherapy tub. The name “Heater Reddy”
appears on the fitting and the fitting is bright red. Two styles of Heater Reddy
fittings are used by manufacturers. The first is a straight flow-through
style, and the second is a tee style that connects direct to the discharge port
of the pump. If the Heater Reddy fitting
is not connected directly to the discharge port of the pump, it is a
flow-through style fitting. (See Fig. 2)
Step
3
- Before
starting installation, you will need to verify that your Redhead heater is the
correct model for your model hydrotherapy bathtub. This is accomplished by
locating the white sticker that has been affixed to the Heater Reddy
fitting. This white sticker will normally be located on the top of the
Heater Reddy fitting. Compare
the number located on the white sticker with the numbers listed on the
Compatibility Sheet that is packed with your Redhead heater. You cannot install
a tee style heater on a flow-through style Heater Reddy
fitting or vice versa. In addition, your manufacturer may have special
requirements for your heater, so it is important that you confirm that the
number shown on the white label affixed to the Heater Reddy
fitting matches one of the numbers on the Compatibility Sheet packed with
your heater.
IMPORTANT!
If your Redhead heater style does not
match the Heater Reddy fitting style
and one of the model numbers shown on the Compatibility Sheet, return the
Redhead heater to the place where it was purchased and exchange it for the
proper model Redhead heater before proceeding further.
Step
4 -
If
the Heater Reddy fitting
is attached directly to the hydrotherapy jet pump (a tee style fitting), do not
remove the Heater Reddy fitting from
the jet pump until you have successful cut through the red plastic Heater Reddy
fitting in the two cutting grooves provided. Tee style Heater Reddy
fittings will be supported by the pump while the Heater Reddy
fitting is being cut. If the Heater Reddy fitting is not a tee style,
carefully support the piping on each side of the Heater Reddy
fitting when cutting through the fitting as described below.
Step
5 - Using
the wire saw provided with the Redhead heater, place the wire portion of the saw
into one of the two cutting grooves that are visible in the horizontal
portion of the Heater Reddy fitting. You will find the two cutting grooves
located to the left and right of the center of the fitting, just inside the
large male threaded portion of the Heater Reddy fitting. These cutting grooves
ensure that you will make a proper cut in the proper location. (See Fig. 3)
Step
6
-
Once you have properly placed the wire saw into the first cutting groove
(parallel with the cutting groove), cutting can begin by holding the wire saw
with one hand on each of its two handles and sawing back and forth by slowly
pulling first on one handle of the wire saw and then on the other handle of the
wire saw. DO NOT CUT
QUICKLY! While
it takes only a few seconds to cut through the plastic body of the Heater Reddy
fitting, moving the wire saw back and forth too rapidly can develop heat
in the cut and the cut-out and stationary parts of the Heater Reddy
fitting may fuse together slightly from the heat generated by the wire
saw. Fusing will not leave the cut as smooth upon completion of the cut as it
will if you saw slowly. CUT
SLOWLY AND BE PATIENT!
Step
7
- When you have successfully
completed the first cut, repeat Steps 4 and 5 on the Heater Reddy
fitting at the opposite end of the fitting in the similar cutting groove
provided.
Step
8 - Once
you have successfully cut through both ends of the Heater Reddy
fitting in the cutting grooves, the unused portion of the fitting (not
attached to the piping system) can be removed from the piping system. If the
Heater Reddy fitting is a tee style,
remove the unused portion of the fitting by unscrewing the large union nut that
attaches the Heater Reddy fitting to
the pump. If the Heater Reddy fitting
is a flow-through type, completing the second cut will allow the unused portion
of the Heater Reddy fitting to be
removed from the piping system. Discard the unused portion of the Heater Reddy
fitting. (See Fig. 4)
Step
9—
Check the cuts on the remaining portion of the Heater Reddy
fitting and remove any loose plastic burrs left on the fittings to ensure
a proper installation of the Redhead heater.
Step
10 - Packed
with your Redhead heater you will find two (2) white round flat rubber donut
shaped gaskets. (See Fig 1) Remove them from the package and install one against
the Heater Reddy fitting surface
adjacent to the cut you made with the wire saw and up against the red large
thread’s vertical flat surface. The gaskets will be held in place by that
portion of the Heater Reddy fitting that protrudes through the center of the
white gasket after they-are installed on the Heater Reddy fitting. Continue the
installation by the placement of the second white gasket on the opposite Heater
Reddy fitting in the same manner.
Step
11 -
Remove
the Redhead heater from its carton. You will note that there are two large
silver colored Ring Nut™ union nuts on opposite ends of the heater. Tee style
heaters will have a third large non-removable nut to attach the heater to the
pump. The two silver Ring Nuts need to be removed from the Redhead heater for
use later in the installation, as they are installed on the Redhead heater
initially for shipping purposes only. (See Fig. 5)
Step
12 - To
remove the silver Ring Nuts from the
Redhead heater, hold the Redhead heater firmly with one hand and with your free
hand, slide the one-piece Ring Nut’s outer retaining ring outwardly from the
center of the heater until it disengages from the heater and leaves two threaded
Ring Nut pieces on the heater body.
Remove the two threaded pieces by pulling them apart. Set the Ring Nut’s
outer retaining ring and the two threaded pieces-aside for later use in
the installation. Repeat the removal of the second silver Ring Nuts retaining
ring and two threaded pieces located on the opposite end of the heater. (See
Fig. 5)
Step
13 - The
silver Ring Nut’s
outer
retaining rings have one opening larger-tharrthe other. Verify the small
and large openings. With the small opening facing the large red threads on the
Heater ReddyT fitting,
slide one of the silver Ring Nut’s outer
retaining rings over and past the
large
red threads of the
Heater Reddy fitting
until it
goes past the red
Heater Reddy fitting
and
rests on the piping. Repeat this on the opposite end of the Heater Reddy
fitting. The
Redhead heater is now ready to be installed and secured onto the piping of the
hydrotherapy tub. (See Fig 5)
Step
14 -
You
will note that the distances left between the two white gaskets on the Heater
Reddy fitting
nearly exactly matches the length of the Redhead heater. Slide the Redhead
heater into the space left between the white gaskets. If the Redhead heater is a
tee style, secure the heater to the pump by the pump union nut located on the
tee portion of the Redhead heater, being careful to first place the sealing
gasket provided onto the pump-outlet where it mates up against the silver tee on
the Redhead heater. Tighten the pump union nut by hand until it is secure.
Step
15 - To
attach the Redhead heater to the hydrotherapy system’s piping by taking the
two thread halves of the silver Ring Nut and
place them around the Redhead heater body and over the red threads of the
Heater Reddy fitting. The metal
flange on each end of the Redhead heater is to be located in front of the
retaining portion of the two Ring Nut threaded halves and is to come to rest
against the white gasket on each end of the Heater Reddy
fitting. Make sure that you have aligned the threads of the two Ring Nut
threaded halves with the threads on the Heater Reddy fitting before you secure
them in place with the Ring Nuts one-piece retainer ring. (See Fig. 6)
Step
16 - Once
proper alignment of the flange and threads is established, slide the Ring Nut’s
one-piece
retainer ring towards the Redhead heater until it stops and cannot go further.
You will know that you have gone far enough and have correctly accomplished the
installation of the Ring Nut’s outer retaining ring when the front and back
surfaces of the Ring Nut’s one-piece retainer ring are flush with the front
and back surfaces of the thread halves of the Ring Nut.
Repeat this procedure on the opposite end of the Redhead heater until you have
successfully completed installation on that end as well. The heater installation
in the piping system is nearly complete. (See Fig. 6)
Step
17 - Verify
that all of the Redhead heater’s threaded components are properly aligned with
the threaded surfaces that they mate to. Firmly hand tighten all large nuts so
they are firm and secure up against the mating sealing surfaces and they cannot
be tightened further using hands. If a wrench is used to tighten the plastic
nuts, they can be cracked, so use a wrench very carefully and do not
over-tighten.
Step
18 - Prior
to testing your installation for leaks, you must complete the electrical bonding
of your Redhead heater to the bonding system of your hydrotherapy tub. Your
manufacturer has provided an unused bonding lug to electrically bond the Redhead
heater to the electrical system of your tub. Read the manufacturers instructions
to locate the bonding lug provided for electrical bonding of the Redhead heater.
Packed with your Redhead heater is a 36 inch long #8 bare copper wire. This wire
is provided for your use to complete the electrical bonding of the Redhead
heater to the manufactures bonding lug that is provided. (See Fig 7)
Step
19
- Secure one end of the #8 copper wire to the bonding lug provided on the Redhead
heater and the other end of the #8 copper wire to the manufacturers’ bonding
lug. Securing of the bonding wire is accomplished by placing the #8 copper wire
into the pressure connector on the bonding lug, and then by tightening the
pressure connector screw on the bonding lug with a screwdriver. All electrical
wiring and bonding must be done as specified in Article 680,-National Electrical
Code and your local Building Code. If you are unsure of how to wire or
electrically bond your Redhead heater, contact a Licensed Electrician to perform
the electrical installation and bonding of your Redhead heater for you. DANGER
-
RISK
OF ELECTRICAL SHOCK —
RISK
OF INJURY OR DEATH IF ELECTRICAL INSTALLATION AND BONDING ARE NOT DONE
PROPELY.
If you are in doubt, have this important work done by a Licensed Electrician!
Step
20 - Your
Redhead heater is provided with a 36 inch long 18/3 grounded power cord. Some
models of the Redhead heater have a NEMA male plug on the end of the power cord,
while others have a Ground Detector located in a small black box on the end of
the power cord. The purpose of the
Ground Detector on the end of the power cord is to ensure that your electrical
receptacle has a proper ground and has proper polarity.
Plug the power cord’s NEMA plug or Ground Detector plug into a GECI
protected 120V power source.
GROUND
DETECTOR INSTRUCTIONS:
- (Note: ONLY
PLUG THE GROUND DETECTOR INTO A 120V ELECTRICAL RECEPTICAL)
If your unit is equipped with a
Ground Detector on the plug end of the electrical power cord, and if after you
plug it into your electrical supply receptacle,
it shows the Red indicator light ON, YOU
HAVE AN UNSAFE CONDITION DUE TO NO GROUND BEING PRESENT IN YOUR ELECTRICAL
RECEPTICAL. When this
happens, the Redhead heater will not receive power to operate until the Red
indicator light is OFF (which will happen either if you have a proper ground
initially, or after you have established a proper ground if one was not
previously present) Once you have
established a proper ground, the Ground Detector checks next for proper polarity
of the electrical receptacle. Polarity
checking verifies that the Hot and Neutral wires are wired correctly to the
receptacle and are not reversed. If
you find both the Red light ON and the second Yellow light ON, then your
polarity is reversed and YOU HAVE AN UNSAFE
CONDITION. Unplug the
Ground Detector and correct the polarity at the electrical receptacle.
When the condition is corrected, plug the heater Ground Detector back in
to the electrical receptacle. If
the Ground Detector verifies both proper
ground and proper polarity, all lights will be OFF and power will be transferred
to your Redhead heater which will operate automatically thereafter.
Consult the Owners Manual for troubleshooting your heater after proper
electrical installation is completed.
REMEMBER:
Red Light ON
= Open ground. Red
Light and Yellow Light ON = Reversed Polarity
Red Light and
Yellow Light OFF = Ground and Polarity are correct and power is
available to operate the heater.
The
hydrotherapy system pump and your Redhead heater may possibly be powered from a
single 20 Amp 120V GFCI protected 3-wire power source equipped with a duplex
receptacle if your installation meets the following criteria.
To use a single duplex receptacle for both the hydrotherapy jet pump and
the Redhead heater, you must first verify that the combined electrical ratings
of both components does not exceed 15 Amps (The Redhead heater draws 5.3 Amps ).
Therefore, to utilize a single electrical circuit, the pump must be rated
at 120V and 9.7Amps maximum. If
the pump is rated at any other voltage or at 120V but 9.8 Amps or more,
then two individual electrical circuits must be provided for your installation
to power both the heater and the pump. No
electrical interlocking of the pump and heater is required as this function is
contained within the safety design of the Redhead heater.
Consult the hydrotherapy bath manufacturers Installation Manual for 240V
pump electrical installation instructions. (See Fig 7)
Step
21 -
Your
installation must be hydrostatically tested for leaks before your installation
is complete to make sure you have successfully installed your Redhead heater.
This is accomplished by first filling the tub SLOWLY
with water until the water is above
the elevation of the Redhead heater. IMPROPER
INSTALLATION OF THE REDHEAD HEATER CAN RESULT IN WATER LEAKING FROM THE PIPING
SYSTEM! WATER DAMAGE CAN
OCCUR TO SPACES BELOW OR ADJACENT TO THE HYDROTHERAPY BATH. Do not
leave the tub unattended during the testing process and only fill the tub with
enough water to raise the level of water in the tub to above the Redhead heater.
FILL THE TUB SLOWELY SO FILLING CAN BE
STOPPED IF A LEAK IS DETECTED. DRAIN
THE TUB IMMEDIATELY IF A LEAK IS DETECTED AND CORRECT THE LEAKING PROBLEM BEFORE
RE -TESTING THE SYSTEM. (See Fig. 8)
Step
22 - If
the above hydrostatic test of the piping system verifies that no leaks are
present, you can perform the final REQUIRED
hydrostatic leakage test by first filling the tub with water above the elevation
of the heater, checking visually for leaks and if none are present, turn the
hydrotherapy pump ON. It is suggested that the system run for 30 minutes
minimum. The tub should be filled with cold water so you can check to make sure
the heater ON light is ON. It is visible on the cover of the Redhead heater. If
the light is not ON, check the troubleshooting section of the Owner’s Manual
packed with your Redhead heater.
