Owner's Record
Jacuzzi Whirlpool Bath does not recommend prolonged periods of use of the steamer. Prolonged use of the steam
system can raise the internal human body temperature excessively and impair the body's ability to regulate its internal
temperature (resulting in hyperthermia). Consult your physician about your safety and comfort before using the steam
system; limit your use of steam to 10-15 minutes until you are certain of your body's reaction. A cooling shower spray
can be used simultaneously with the steam to assist in regulating your body temperature.
Alcohol, certain drugs or medications such as tranquilizers affect a person's ability to withstand high temperatures and
may produce dangerous side effects. Do not use alcohol or drugs when using the J-Dream II.
The elderly, the infirm, and children should not use the J-Dream II unattended. Pregnant women and people with heart
conditions should consult their physicians before using the steamer.
The wet surface of the J-Dream II can be slippery. Use care when entering and exiting.
When using the J-Dream II, basic safety precautions should always be followed:
This unit is to be connected to a Ground Fault Circuit Interrupter (GFCI). This is also known as an Earth Leakage Circuit
Breaker (ELCB). Check at least once a month to be sure this is operational. With the unit operating, push in the test
button. The unit should stop operating and the trip indicator should appear. Restore the power; push to OFF, then
turn ON. The unit should now operate normally. If the interrupter fails to operate in this manner, there is a fault in the
electrical system or the GFCI and you may not be protected from an electrical shock. Turn off the power and have
a qualified electrician check the circuit before using it again.
Do not use electrically connected devices such as television, radio, or stereo speakers, lights, hair dryers, or
telephones within 1.5 m (5 feet) of the J-Dream II while in use.
Read manufacturer's safety information with all optional equipment.

J-Dream II Owner's Manual
When Jacuzzi introduced the first whirlpool bath in 1968,
it changed the bathtub forever. Now Jacuzzi is
revolutionizing yet another form of bathing - the shower.
The J-Dream II™, a fully-adjustable system massages,
soothes, steams and invigorates you into a state of
complete well-being.
A cascading waterfall, 32 hydrotherapeutic jets, a powerful
steam nozzle and two adjustable showerheads create a
personal bathing experience like no other. An easy-to-use
control panel lets you adjust the intensity and duration of
each function.
The J-Dream II's 32 hydrotherapy jets provide high power
hydromassage to invigorate and relax the body. Preset
the jets to pulsate in variuos configurations, adjusting both
the spray pattern for each jet and the rate at which you
want the jets to pulsate. Fast and invigorating or slow and
luxurious - the choice is yours.
Step into the J-Dream II and see how Jacuzzi has created
the ultimate shower experience. Because the J-Dream II
is made by Jacuzzi, everything about it - from innovative
design and technology to quality manufacturing - is simply
the best.
Rest on the specially molded seats and relax as a soothing,
cascading waterfall caresses your neck and shoulders.
The cascade shower is specially designed to release
tension from the entire upper spine area, and create a
feeling of well-being throughout your body.
The touch of a finger activates the electronically controlled
steam system to fill the J-Dream II with full-bodied steam.
In just minutes, you can enjoy all the cleansing benefits of
steam heat - without stepping outside the shower.
The hand-held shower heads offer a range of sprays from
fine mist to full-flood. Even the water temperature can be
preset, so you won’t have to adjust it each time. The hand-
held shower can also be adjusted vertically so even the
tallest adult and the smallest child can shower in complete
comfort.

J-Dream II Owner's Manual
Read all instructions before beginning assembly and installation.
General Assembly Information
The J-Dream II shower unit is installed into a niche with the drain towards the left hand side of the unit as you face the shower door.
This manual details the assembly, installation and operation. After the drain, water supply stub-out, and electrical supply are provided,
the shower unit should be assembled freestanding away from the walls of the room. Next connect and static test the water supply
lines. The electrical connections should then be completed before the unit is moved into final position, drain fit is rechecked, and
assembly is completed before final testing.
Room Construction: Important
The room where the shower unit is to be located must be constructed of materials that can withstand excessive amounts of moisture
and condensation. Large amounts of steam can be released into the room when the shower door is opened. Providing natural or
forced ventilation of the room will help maintain comfort and minimize moisture damage to the building. Jacuzzi Whirlpool Bath is
not responsible for damages resulting from excess moisture or water spillage. Consult an architect or engineer for aid in designing
your interior structure. Do not install heat lamps directly above the shower unit. The clear top will deform from excess heat.
Water Supply Required
The water supply must be capable of delivering 6 gallons per minute minimum to the unit within a pressure range of 30-65 PSI (2.1-
4.6 BAR). Pressures in excess of 65 PSI (4.6 BAR) must be reduced with a regulator in the supply line. This is the amount of water
and pressure required to ensure adequate performance of the J-Dream II, it is not the water consumption rate.
NOTE: DO NOTprovide less than minimum flow specified. Negative pressure under certain conditions could cause a health hazard by
fouling of the house potable water supply.
Electrical Power Required
See Specifications for power required. Power supplied to the unit must be through a *GFCI protected, dedicated circuit with proper
bonding and grounding. The GFCI must be located in an area that will allow access for frequent testing.
* GFCI ( Ground Fault Circuit Interrupter) is also known as an ELCB ( Earth Leakage Circuit Breaker.) This device must be a type
approved by electrical codes and standards to protect users from potential electrical hazards.

Electrical requirements
Your J-Dream II, as it comes from the factory, requires a GFCI protected 220/240 VAC 15 AMP 3-wire circuit (2 conductor with ground)
for single (1) phase electrical service, and must be in a separate circuit having no other appliance connected in that circuit. If you
do not have this kind of circuit, a qualified electrician should be called in to install the necessary wiring. Inadequately sized wiring or
locating the unit too far from the main service panel may cause a voltage drop. A drop in voltage can cause the unit to malfunction
and bring about permanent damage to the shower's electrical system. The circuit ground wire must be provided to take advantage
of the designed-in safety features of the J-Dream II. Bond according to procedure described on page 23. Caution: Without proper
grounding and bonding, a system malfunction may cause fatal shock.
Electrical precautions
Lighting and electrical receptacles must be located at least 5 ft (1.5m) from the J-Dream II. Lighting located between 5 ft and 10
ft (1.5m and 3m) from the J-Dream II must be on a circuit protected by a GFCI. Do not use electrically connected devices, such as
television, radio, telephones, stereo speakers, lights or cooking devices within 5 feet of the J-Dream II while it is in use.
Ventilation
Water which drips on the floor during exit from the J-Dream II may cause a walking hazard and/or structural damage unless proper
waterproof building materials are used in the area surrounding the unit. Take into consideration, also, the high room humidity which
will exist due to use of the steamer. Providing natural or forced ventilation of the room will help maintain comfort and minimize moisture
damage to the building. Jacuzzi Whirlpool Bath is not responsible for damages resulting from excess moisture or water spillage.
Consult an architect or engineer for aid in designing your installation.
Maintenance
Cleaning the J-Dream II
To clean your J-Dream II, simply use a mild non-abrasive liquid detergent or commercially prepared bathtub cleaners. Do not use
abrasive cleaners. You can protect and restore the gloss to a dulled surface by applying a plastic polish specifically designed for
use on acrylic finishes (methylmethacrylate). If an acrylic polish is not available, an automotive paste wax will do.
Repairs to the surface
Minor scratches which do not penetrate the color finish (acrylic) can be removed with 600-grit wet/dry sandpaper. Restore the glossy
finish with an acrylic polish or a comparable automotive paste wax.
Major scratches or gouges which penetrate the acrylic surface will require refinishing. Ask your dealer for special instructions.

IMPORTANT: This is the installed position of
the waste stub-out when connected to the
shower drain. If the stub-out is installed before
the shower unit, leave enough flex in the waste
line to allow the end of the stub-out to be
blocked temporarily (see page 10) in a position
under flush to the floor surface. This will allow
the shower unit to slide across the floor into
position without having to lift it.
IMPORTANT: The shower drain is designed
to connect to a 2 inch (50mm) ABS or PVC (as
approved by local codes/standards) waste
stubout.
End of 2 inch (50 mm) waste stubout must be
located to these dimensions within 1/4 inch

Locate Base to provide assembly access to all sides
Remove Base from carton labeled Base/Top. Place Clear Top in carton to prevent damage.
(The Clear Top will not be installed until the unit has been fully assembled and plumbed).
Position the J-Dream base on the floor so that you have work access to all four sides of the
unit during assembly. (Allow a minimum of 24" (600 mm) of access on each side of base.)
Before starting assembly, position the base pointing in the same direction as it will be in the
final installation position so no unnecessary turning of the unit is required.

Drain Fitting (provided with unit)
Leave enough flexibility in the waste line to allow the end of the stub-out to
be blocked temporarily in a position under flush with the floor surface. This
will allow the shower unit to slide across the floor into position without
having to lift the shower unit.
Remove the block and pull the drain assembly up to insert the stub into the drain.
The drain fitting is a non-caulk type (compression fitting) drain. Make certain that the
locking ring is loose to allow the drain stub to insert easily inside the rubber compression
sleeve. If necessary, lubricate the sleeve with a mild soap solution. The drain stub must
extend well into the rubber sleeve before the locking ring is tightened. Use a screwdriver
and the assembly tool provided to tighten the locking ring.
