bath operation. The steam bath function is controlled with a safety device (indicated by a faucet with a water drop
symbol on the display). This safety device operates in the event that water has been turned off before the steam timer
reaches 00. If the steam water level drops below the minimum level, the red light (13, Figure 1) above the faucet symbol
will come on and an audible signal will sound warning that the water flow from mixer Y has stopped. This occurs
approximately 5 minutes after the flow has ceased. If water is not restored to the steamer unit at this time, the steam
bath function will be cancelled.
The electronic device has a self test program which checks all functions when the power is turned on. All the lights
on the display turn on in a programmed test sequence lasting 8 seconds and testing 14 events. The end of the test
sequence leaves the steam digital time display (Figure 1) reading (--).
In case of power failure while the J-Dream is operating, any function will be completely cancelled. When power is
restored, the self test will activate and any function can be reset at this time.
The electronic unit is equipped with an internal safety program which automatically cancels any function if a program
has not been completed within 60 minutes.
Before changing from the hydromassage to the steam bath function, or vice versa, the water in the holding tank will
be automatically exchanged, which requires approximately a 60 second waiting period. This feature is incorporated
to decrease deposit buildups in the steam generator.
Use the hand shower while steam is operating
Follow the steps below to operate the hand shower during steam operation without turning off the steam function. This
procedure avoids the drain/fill/heat-up cycle that occurs when the steam control is turned off and back on again at the
control panel.
1. During normal steam operation, the transfer valve is in the middle position as shown in Figure 2 and the mixer valve
is open, or “ON”.
2. Without changing the electronic control panel settings, turn the transfer valve handle to the “handshower”
position. Water will flow from the handshower, and the mixer handle may be used to adjust the water temperature.
The steam mode will continue to function.
3. When you have finished cooling down or rinsing off with the handshower, turn the transfer valve handle back to the
middle position leaving the mixer handle “ON”.
The water flow will stop at the hand shower, and the mixer valve will then continue to provide water to the steam
generator as required.
Maintenance
Routine Maintenance
The shower head is equipped with a filter which must be occasionally cleaned of limestone and other deposits. The
filter is placed between the flexible hose and the shower head. If limestone deposits are on the jet nozzles, the shape
of the water jets may be altered. Remove and clean the nozzles occasionally. Forcefully turn the nozzle counterclock-
wise until a click is felt. Then remove the nozzle and clean it by soaking it in a moderate vinegar and water solution.
Do not use metal tools (such as scissors or screwdrivers, etc.) to clean the nozzle. For routine cleaning of plastic
surfaces, such as the side panel, the shower wall panel, etc., use a mild liquid detergent only. Do not use abrasive
cleaners, alcohol, or other solvents. Any normal polish can be used to keep acrylic surfaces shiny. The glass panels
can be cleaned with any glass-cleaning product available on the market. Do not use abrasives, solvents, or acetone
on any part of the J-Dream.
Special Maintenance Operations, Hard Water Areas
If the steam bath is used frequently in a hard water area, particles of limestone may be deposited in the steam generator
and reduce its performance. Jacuzzi Whirlpool Bath recommends the installation of a water softener unit, in order to
eliminate or reduce limestone deposits. Jacuzzi Whirlpool Bath also recommends the installation of a particle filter
because the solenoid valve can be obstructed by large particles in the water, thus causing malfunctions.
To be sure that water conditions in your area will not require the installation of a water softener unit or a particle filter,
consult a professional plumber. In a hard water area, filter screens in the solenoid valves may become obstructed over
time or with heavy use. If the procedures under " Routine Maintenance Operations" do not correct a flow problem,
call a qualified service technician to inspect and clean the solenoid valve filter screens, located in the equipment area
of the shower unit. The valves are accessed through the vertical fixed panel adjacent to the sliding shower doors. The
valves can also be accessed by removing 3 screws located between the glass and the edge of the seatwall and pivoting
the seatwall inward.
IMPORTANT:When installing the shower unit, be sure to leave adequate clearance to allow the removal of the
vertical panel for service access.
