J-DREAM II
Shower System
IMPORTANT SAFETY INFORMATION
READ ALL INSTALLATION INSTRUCTIONS
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.
Note: This is a professional grade product. A good knowledge of construction techniques, plumbing and
electrical installation according to codes are required for proper installation and user satisfaction. We
recommend that a licensed contractor perform the installation of all Jacuzzi Whirlpool Bath products. Our
warranty does not cover improper installation related problems.

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 NOT provide 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.

J-Dream II Owner's Manual
Electrical requirements
Your J-Dream II, as it comes from the factory, requires a GFCI protected 240 VAC 3- wire 20 AMP 50-60 Hz 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 feet (1.5 meters) from the J-Dream II. Lighting located between
5 feet and 10 feet (1.5 meters and 3 meters) 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 JDream 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 nonabrasive 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
