WARNING
Prolonged immersion in hot water may induce hyperthermia.
Hyperthermia occurs when the internal temperature of the body reaches a level
several degrees above the normal body temperature of 98.6°F (37 °C). The
symptoms of hyperthermia include dizziness, fainting, drowsiness, lethargy, and
an increase in the internal temperature of the body.
The effects of hyperthermia include:
• Unawareness of impending danger
• Failure to perceive heat
• Failure to recognize the need to exit spa
• Physical inability to exit spa
• Fetal damage in pregnant women
• Unconsciousness resulting in a danger of drowning
To Reduce the Risk of Injury -
• The water in a spa should never exceed 104°F (40°C). Water
temperatures between 100°F (38°C) and 104°F (40°C) are
considered safe for a healthy adult. Lower water temperatures are
recommended for young children and when spa use exceeds 10
minutes.
• 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 spa water
temperatures to 100°F (38°C).
• Before entering a spa or hot tub, the user should measure the water
temperature with an accurate thermometer since the tolerance of
water temperature-regulating devices varies.
• The use of alcohol, drugs, or medication before or during spa or
hot tub use may lead to unconsciousness with the possibility of
drowning.
• Obese persons and persons with a history of heart disease, low
or high blood pressure, circulatory system problems, or diabetes
should consult a physician before using a spa.
• Persons using medication should consult a physician before using
a spa or hot tub since some medication may induce drowsiness
while other medication may affect heart rate, blood pressure, and
circulation.

WARNING
• People with infectious diseases should not use a spa or hot tub.
• To avoid injury, exercise care when entering or exiting the spa or
hot tub.
• Do not use drugs or alcohol before or during the use of a spa or
hot tub to avoid unconsciousness and possible drowning.
• Pregnant or possibly pregnant women should consult a physician
before using a spa or hot tub.
• Water temperature in excess of 100°F (38°C) may be injurious to
your health.
• Before entering a spa or hot tub measure the water temperature
with an accurate thermometer.
• Do not use a spa or hot tub immediately following strenuous
exercise.
• Prolonged immersion in a spa or hot tub may be injurious to your
health.
• Do not permit any electric appliance (such as a light, telephone,
radio, or television) within 5 ft. (1.5 m) of a spa or hot tub.
• The use of alcohol, drugs or medication can greatly increase the
risk of fatal hyperthermia in hot tubs and spas.
CAUTION
It is important to note that certain materials used in and around
swimming pools and spas may not be compatible with chemicals
commonly used to purify pool and spa water (e.g. acids, chlorine, salt,
stabilizers, etc.).

Page 6 ENGLISH Jandy®TruSense Water Chemistry Analyzer | Owner’s Manual
DRAFT
WARNING
When mixing acid or other chemicals with water, ALWAYS ADD THE
ACID OR CHEMICALS TO WATER. NEVER ADD WATER TO THE
ACID OR CHEMICALS.
Some helpful considerations may include:
• Choosing plants that can withstand splash out of pool water containing
chlorine and/or salt and other water purication chemicals.
• All metal components used in and around a pool should be of a high
grade, quality stainless steel.
• Careful selection of masonry products. The porosity and hardness of
natural stones varies greatly. Therefore we recommend you consult with
your builder or stone contractor on the best choice for stone materials
around your pool or spa.
• Sealing all masonry products. Professionals in the stone industry specify
that even natural stone, especially when used outdoors, be sealed to
prevent weathering, staining, and premature degradation. Consult with
your stone or deck contractor for the proper sealer for the masonry
products you have selected to use around your pool or spa.
• For the optimal results, sealers should be reapplied on a regular basis.
Reapply the protective sealer on a schedule per the manufacturer’s
instructions.
• Use of chemicals other than those recommended may be hazardous.
Follow the chemical manufacturers instructions.
CAUTION
In order to avoid premature failure or damage to the equipment, protect
the equipment from direct water exposure from sprinklers, water runoff
from rooftops and drainage, etc. Failure to comply may cause equipment
failure, and may also void warranty.

SAVE THESE INSTRUCTIONS
WARNING/SHOCK HAZARD
Follow all applicable electrical codes. Prior to installation or performing
any service, turn off all switches and the main breaker in the pool/spa
pump electrical circuit. Failure to comply may cause a shock or hazard
resulting in severe personal injury or death. While disconnecting and/or
connecting any electrical wiring, be careful not to damage or abrade any
of the wiring.
WARNING
Do not connect the system to an unregulated city water system or other
external source of pressurized water producing pressures greater than 35
PSI.
To minimize risk of severe injury or death, filter, pump, and pH and ORP
Sensors should not be subjected to the piping system pressurization test.
Local codes may require the pool piping system to be subjected to a
pressure test. These requirements are generally not intended to apply to
the pool equipment, such as filters, pumps, water chemistry analyzers, or
chlorinators.
If, however, the WARNING cannot be followed and pressure testing of the
piping system must include the filter, pump, water chemistry analyzers
and/or chlorinator, BE SURE TO COMPLY WITH THE FOLLOWING
SAFETY INSTRUCTIONS:
• Check all clamps, bolts, lids, lock rings, and system accessories to
ensure they are properly installed and secured before testing.
• Remove the pH and ORP sensors from Jandy TruSense Water
Chemistry Analyzer and use the provided plugs.
• RELEASE ALL AIR in the system before testing. AIR PRESSURE must
NOT be used for pressure testing.
• Water pressure for test must NOT EXCEED 35 PSI.
• Water temperature for test must NOT EXCEED 100°F (38°C)
• Limit test to 24 hours. After test, visually check system to be sure it is
ready for operation.

Section 2. General Overview
2.1 Product Overview
This manual provides instructions for installing the Jandy TruSense Water
Chemistry Analyzer.
NOTE: Installation of the Jandy AquaLink®RS Revision X or later is
required prior to the installation of the Jandy TruSense Water Chemistry
Analyzer.
Sensors measure the following:
• pH (hydrogen potential): this value measures the acidic or basic
character of a medium. pH contributes to the eectiveness of the
disinfectant.
• ORP/REDOX (measurement of active sanitizer in mV): The ORP
measurement is reected in millivolts (mV). The measurement taken by
the ORP probe is a voltage expressed in millivolts (mV), which repre-
sents the more or less oxidizing nature of the water. Only available on
TRUSENSE model.
• Bonding lug helps reduce stray current.
