SECTION 1.
General Information

1.1 Introduction

This manual provides installation and operation

instructions for the Jandy Lite2 Model LD pool and
spa heater. Read these installation and operation
instructions completely before proceeding with the
installation. Consult the Jandy factory, or local factory
representative, with any questions regarding this
equipment.

Certain sections of this manual are specific to

either United States or Canadian installations, and are
labeled as such.

The Lite2 LD heater gets electrical power from

an external 120VAC or 240VAC source and provides
a dual thermostat Flex-Temp control system for pool/
spa combinations or preheat convenience. The Lite2
LD heater also meets the California, New York,
Hawaii, and Oregon state energy requirements for
intermittent ignition gas appliances.

The Lite2 heater is specifically designed for

heating fresh water swimming pools and spas, and
with proper installation and care, they will provide
years of reliable service. Do not use the heater to
maintain pool or spa water temperature below 70°F.
Do not use it as a heating boiler or general service
water heater or to heat salt water. Consult your dealer
for the appropriate Jandy products for these applica-
tions.

1.2 Consumer Information and Safety

The Lite2 Pool/Spa heater is designed and

manufactured to provide many years of safe and
reliable service when installed, operated and main-
tained according to the information in this manual and
the installation codes referred to in later sections.
Throughout the manual safety warnings and cautions
are identified by the "

" symbol. Be sure to read and

comply with all of the warnings and cautions.

1.2.1 Spa/Hot Tub Safety Rules

WARNING

The following “Safety Rules for Hot Tubs,”
recommended by the U.S. Consumer Product Safety
Commission, should be observed when using the
spa.

AVERTISSEMENT

Les Règlements suivants pour Cuves Thermales, tel
que recommandés par la Commission U.S. de
Sécurité des Produits pour les Consommateurs,
devraient être respectés lors de l’utilisation du spa.

WARNING

The U.S. Consumer Product Safety Commission
warns that elevated water temperature can be
hazardous. Consult heater operation and installation
instructions for water temperature guidelines before
setting temperature.

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 tube 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 4°F (2°C).

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:
