INSTALLATION INSTRUCTIONS (cont.)
INSTALLATION
Each bath is provided with a cardboard bath well
protector that should be kept in the unit during the
installation and throughout the bathroom construction
process. Overflow drains, fill spouts, and valves must be
installed according to the instructions herein.
See the USER MAINTENANCE INSTRUCTIONS section
of this owner’s manual, prior to Installation, for humidity
and mold prevention suggestions.
Finish Frame1. Afinishframeundertheshellrimshouldalso
always be constructed to support the bath deck and insure
proper drainage toward the bath well. This frame is not
intended to support the full bath weight (s e e Fi g u r e s 1 & 2) .
Jason offers a removable lateral skirt for most baths.
The skirts are available in matching acrylic colors and
provide convenient access to bath equipment as well
as an excellent finished appearance. However, if Ja-
son’s lateral skirt is not used, an access panel MUST
be provided to enable final electrical connections and
service. Please refer to the minimum recommended
access panel size in Table 1 - Specifications.
If a Jason lateral skirt is to be used, the bath deck must
be leveled at 20.5” (52cm) from the support floor or the
skirt will not fit properly.
100% Silicone with mildew resistant properties should2.
be applied between the water resistant backer board and
the deck of the bath. NOTE: If you use a tile flange kit,
modify the framing to support the bath lip as shown
in Figure 1.
A minimum ventilation opening of 2” x 4” (5 x 10 cm) for3.
the blower is required, and should be designed to draw in
indoor ambient air at a minimum of 22°C (72°F).

level; when additional sound insulation is desired; or when
the bath is installed in a drop-in application. In alcove
installations, a bed of mortar may also be recommended
to aid in leveling the bath. NOTE: Do not use a sand bed
to install or level the bath.
Secure the bottom of all equipment mounts so that it9.
is level with the bottom of the bath. Position the bath
in the area of intended installation and cut the equipment
support strap(s) to allow the equipment to rest firmly on the
floor. We recommend securing the equipment mounts to
the floor with removable fasteners for ease of servicing.
Protect the acrylic bath surface from damage during10.
installation with a suitable material, i.e., cardboard
and/or plastic film. The acrylic surface of this bath has
been providedwith a protectivefilmwhichhelpsprotectthe
bathduringshipmentandinstallation. Additionalprotection
may also be required to protect the acrylic surface during
installation. If the bath is tiled in, remove the necessary
portion of the film when installing the tile.
REMOTE MOUNTING OF AIR BLOWER
The Jason AirMasseur system has been factory installed
following E.T.L. Guidelines. During installation, if remote
mounting of the blower is desired or required, the following
procedures should be followed.
NOTE: Do not remote mount the blower more than 15
feet (457cm) away from the air inlet of the bath. Choose
a location as close as possible to the bath to assure
maximum efficiency.
The installer must determine the layout of the piping;1.
exact remote mount location; and service access before
beginning any work. Use 1.5” (38mm) ABS or PVC
plastic tubing. Locate the blower in an area accessible
for servicing. NOTE: A 15 foot extension replace-
ment cable set can be purchased from your Jason
supplier, if needed. To insure proper functioning
of the system, avoid remote mounting in a location
which requires more than six (6) piping direction
changes. A 90° direction change should be made
up of two 45° elbows for maximum efficiency.
If the blower has been factory installed, disconnect the2.
blower from the air bath plumbing by removing the two
(2) screws on the check valve outlet and disconnect the
short piece of flex pipe between the check valve and
the elbow by removing the two (2) screws in the elbow.
(Omit this step on baths where the blower is not factory
installed and remote mounting is required.)
Install the blower in the remote location. The remote3.
mount locations’ ambient air temperature should remain
at approximately 22°C (72°F) for optimum air heating.
Make sure the blower is well ventilated. The blower4.
mount should be attached firmly to the floor. Piping
between the remote blower location and the bath can
be insulated using a minimum of 1/2” (13mm) thick
insulation. Attach new piping to the elbow of the existing
piping.

INSTALLATION INSTRUCTIONS (cont.)
CLEANING
Remove all loose debris.1. Construction plaster or
excess grout can be removed with the use of a wood
(edge) trowel.
Paint or tar stains2. may need to be removed with a
cleaner such as paint thinner, turpentine, or isopropyl
alcohol (rubbing alcohol). Never allow the cleaner to
soak against the acrylic surface for long periods of time.
Always rinse the surface immediately following the use
of cleaners.
Follow the manufacturer’s instructions for safe use of3.
cleaning products. If the surface becomes scratched
or dulled, it may be restored by using a quality plastic
polish, like Novus Plastic Polish No. 2 (available from
the Jason Dealer). It is always preferable to protect
the acrylic surface during installation to minimize
cleanup and prevent surface damage.
WATER TESTING
Before finishing the installation, it is recommended that the
bath be water tested and the plumbing tested for leaks.
Before water testing the bath,1. make sure any pump
unions are hand tight. Do not over tighten or use a pipe
wrench. This will damage the unions and cause leaking.
If the unit leaks with the unions hand tight, then loosen
the unions(s) and check the O-ring seal to ensure it is
properly seated.
Fill and operate the bath.2. Close the drain and fill the
bath with water to at least 10 inches [25 cm] below the
bath deck. The inlet temperature should not exceed 104°F
(40°C) as this could damage the acrylic surface. Refer
to the FILLING AND DRAINING section of this owner’s
manual for more information.
Inspect the plumbing for leaks.3.
Turn the equipment Off and then drain the water.4.
The bath unit and its plumbing are designed to drain
after each use whether used as a hydrotherapy bath,
soaking bath, or when taking a shower.

the Instruction Manual provided with the remote control for
detailed instructions.
Jets
Strategically placed MicroSilk jets are provided for complete
enjoyment of your bath.
Pumps
Pumps provided on Jason baths are factory tested when

AIR HEATER AND AIR TEMPERATURE
The air heater incorporated into the air blower is designed
to preheat the incoming air to body temperature, not to heat
the bath water. The air heater automatically comes on when
the air blower is activated. Even though all air baths provide
preheated air, occasionally some people with sensitive skin
m i g h t e x p er i e n c e a c o l d a i r s e n s a t i o n. T h i s s e n s a ti o n i s c au s e d
by the swiftly moving heated air bubbles blowing on the wet
skin. This phenomenon can be related to the use of a fan for
cooling on a hot day. While the ambient temperature does
not change, the moving air makes you feel cooler. Avoiding
this cold air sensation is among the reasons Jason avoids
placing air jets directly beneath the body. If you experience
a cool air sensation, which is most noticeable during the first
few minutes of an air bath, simply move your body slightly
away from the closest jets.
FLUSHING / SANITIZING
Upon start-up and not to exceed 90 days, your bath and
plumbing system should be flushed. To do so, close the drain
and fill the bath with warm water to at least two (2) inches [5.1
cm] above the highest jet. Pour in Jason Bath System Cleaner
and follow the directions on the bottle. DO NOT use bleach or
other chlorinated cleansers directly on the metal trim.
SUCTION FITTING CLEANING
The cloth suction EZ Clean Pre-Filter is designed to allow for
easy cleaning. If the EZ Clean Pre-Filter becomes soiled or
dirty, it should be removed and cleaned with soap and water.
Once clean, the pre-filter can be fitted around the suction
cover (See Figure 15). Replacement pre-filters are available
from your Jason dealer or from www.jasoninternational.com.
Periodically the internal screen filter should be removed
and cleaned with soap and water. The suction cover can
be removed by unscrewing the single Philips head screw in
the center of the suction cover. Remove the internal screen
filter and clean with soap and water. Replace the screen into
suction cover as shown and reassemble the cover to the fitting
(See Figure 16).
REPAIR
Refer all plumbing or electrical repair to a qualified service
technician.DONOTATTEMPTTORESOLVETHEPROBLEM.
This can result in danger of electrical shock or damage to
the unit and will VOID THE WARRANTY. Remember, when
contacting your dealer or service representative, always have
your serial number, proof of purchase, and model number.
This will insure a quick response on warranty items. The serial
number can be found on the front page of this manual or on
the small card adhered to the back of the bath just above the
equipment.
HUMIDITY
WARNING: AVOID HIGH HUMIDITY LEVELS IN YOUR
HOME. MOLD, MILDEW, FUNGI AND BACTERIA WHICH
MAY BE HARMFUL TO HEALTH THRIVE IN AREAS WITH
CONTINUED HIGH HUMIDITY LEVELS; THEREFORE,
EVERY PRECAUTION SHOULD BE TAKEN TO MAKE
SURE YOUR PLUMBING FIXTURES INCLUDING
BATHTUBS, THERAPY BATHS, OR SHOWERS DO
NOT BECOME A SOURCE OF HIGH HUMIDITY DUE TO
IMPROPER INSTALLATIONS OR LEAKS.
To avoid having your plumbing fixtures become a source of
unwanted humidity, please make sure the following steps
are taken prior to installation.
1. Make sure the area where the bathtub or shower is
installed is well vented and allows enough ventilation and
air circulation to dry the bathroom environment within a
short time after taking a bath or shower.
2. If your bath or shower unit is tiled-in, use units with an
integral tile flange or make sure a tile flange kit or a similar
mechanical barrier is installed to prevent shower spray,
splash, or overflow to leak behind the bathtub.
3. Make sure the plumber properly tests your therapy bath
before it is roughed in to make sure there are no leaks and
it is installed with proper access to bath equipment.
4. Make sure that all the plumbing and fixtures in the bathroom
are in good working order and have no leaks.
5. Do not use carpeting or other materials or furniture, which
can hold moisture in your bathroom.
6. Use disinfectant to clean any bathroom surfaces which
are regularly exposed to moisture.
7. Clean and disinfect humidifier and dehumidifiers as
recommended by the manufacturer. Replace the air filter
on the HVAC unit once a month.
8.Cleanmoldysurfaces as soonasanymoldappearsbyusing
a detergent/soapy solution and appropriate household
cleaner. Always use gloves during cleaning. Dispose of
any sponges or rags used to clean mold.
CLEANING
With minimum care, your acrylic-surfaced bath will retain its
high-luster finish for many years. For regular cleaning use
JasonBath Cleaner or amildNONABRASIVEliquid detergent
solution (i.e. glass cleaner) and a soft, wet cloth or sponge.
Do not run the hydrotherapy system with foaming cleaners
or soaps. Rinse the bath thoroughly after cleaning.
SURFACE MAINTENANCE
Areas with minor scratches or dull surfaces can be
restored by applying commercially available plastic
polish (i.e. Novus Plastic Polish No. 2, available at your
Jason dealer), followed by an application of acrylic paste
wax. Buff the surface with a clean soft cloth. Do not use
sandpaper, steel wool, or abrasive rubbing compounds.

IMPORTANT SAFETY INSTRUCTIONS
INSTRUCTIONS PERTAINING TO THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PER-
SONS.
This manual contains information and instructions for proper operation and maintenance of your therapy bath. Failure to follow these
instructions could result in personal injury, electrical shock, or fire.
WARNING: When using this unit, basic precautions should always be followed, including the following:
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
DANGER: TO REDUCE THE RISK OF INJURY FOLLOW THESE PRECAUTIONS:
A. Do not permit children to use this product unless they are closely supervised at all times.
B. Use this unit only for its intended use as described in this manual. Do not use attachments not recommended by the manufac-
turer.
C. The water in a therapy bath should never exceed 40°C (104°F). Water temperatures between 38°C (100°F) and 40°C (104°F) are
considered safe for a healthy adult. Use time should be limited to approximately 30 minutes, followed by a shower to cool down.
Longer exposures may result in hyperthermia. The symptoms of this condition are nausea, dizziness and fainting, and it can be
fatal. Lower water temperatures are recommended for extended use (exceeding 10 -15 minutes) and for young children.
D. Since excessive water temperatures have a high potential for causing fetal damage during the early months of pregnancy,
pregnant or possibly pregnant women should limit therapy bath water temperatures to 38°C (100°F).
E. The use of drugs or alcoholic beverages before or during therapy bath use may lead to unconsciousness with the
possibility of drowning. Never use the therapy bath while under the influence of alcohol, anticoagulants, stimulants,
antihistamines, vasoconstrictors, vasodilators, hypnotics, narcotics, or tranquilizers.
F. Persons with a medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should
consult a physician before using a therapy bath.
G. Persons using medication should consult a physician before using a therapy bath since some medication may induce drowsiness
while other medication may affect heart rate, blood pressure, and circulation.
DANGER: To reduce the risk of injury, enter and exit the bath slowly. Do not operate this unit unless the suction cover is attached over
the suction inlet fitting and the jet assemblies are installed. There should be at least two (2) inches of water above the highest jet
location during therapy bath operation. NEVER RUN UNIT DRY.
WARNING: Never operate electrically connected devices in or near the bath. Never drop or insert any object into any opening.
This unit must be connected to a supply circuit that is protected by a GFCI. Such a device should be installed by a licensed electrician
and should be tested on a regular basis (at least monthly). To test the GFCI push the TEST button. The GFCI should interrupt the
power. Push the RESET button and the power should be restored. If the GFCI fails to operate in this manner, there is the possibility
of an electric shock. DO NOT USE. Disconnect the unit and have the problem corrected by a qualified service technician.
To avoid the possibility of personal injury and discoloration of the acrylic surface, the inlet water temperature should not exceed
40°C (104°F). The bath should be drained after each use. Each bather should start their bath with fresh water. Do not use oil base
additives in your therapy bath.
CAUTION: Do not use harsh abrasives or solvents for cleaning this unit.
INSTALLER/OWNER BEARS ALL RESPONSIBILITY TO COMPLY WITH ALL STATE
