During the steam bath treatment, the time can always be varied by pressing the (+) and (-) buttons without interrupting the
functions. Also for your convenience, a buzzer will sound when the steam timer reaches zero (00). There is a 10 second
delay before the steam bath function is cancelled. During this delay the timer can be reset to allow more steam 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 2) 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 2) reading (--).
In case of power failure while the J-Dream 90 is operating, any function will be completely cancelled. When power is restored,
the self test will activate and any desired 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 is to decrease deposit buildups
in the steam generator.
Ordinary Maintenance Operations:
The shower head is equipped with a filter which must be occasionally cleaned due to 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 counterclockwise 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 90.
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 "Ordinary Maintenance Operations" do not correct a flow problem you might experience,
call a qualified service technician to inspect and clean the solenoid valve filter screens which are 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 seat wall and pivoting
the seat wall inward.
IMPORTANT: In the shower unit installation, provide adequate clearance to allow the removal of the vertical panel
in the event that service becomes necessary.
