There is a specially designed model of Lite2 for
heating salt water pools. Consult your dealer for the
appropriate Jandy products for these applications.

AVERTISSEMENT
La U.S. Consumer Product Safety Commission
indique que des températures de l'eau élevées
peuvent être dangereuses. Voir la notice
d'installation et de fonctionnement pour le
réglage de la température.
1.
Spa or hot tub water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for
a healthy adult. Special caution is recommended
for young children.
2.
The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and
subsequently result in drowning.
3.
Pregnant women take note!
Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the first three months of pregnancy (which
could result in the birth of a brain-damaged or
deformed child). If pregnant women are going to
use a spa or hot tub, they should make sure the
water temperature is below 100°F (38°C)
maximum.
4.
The water temperature should always be
checked with an accurate thermometer before
entering a spa or hot tub. Temperature controls
may vary by as much as 1F° (1C°).
5.
Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.
6.
Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.
7.
Prolonged immersion in hot water can induce
hyperthermia.
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and an
increase in the internal body temperature. The effects
of hyperthermia include:
Lack of awareness of impending hazard
Failure to perceive heat
Failure to recognize need to leave spa
Physical inability to leave spa
Fetal damage in pregnant women
Unconsciousness resulting in a danger of
drowning
