SECTION 1.
General Information
1.1 Introduction
This manual provides installation and operation
instructions for the LX and LT Low NOx pool and
spa heaters. 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 LX and LT Low NOx heaters get their
electrical power from an external 115VAC or
230VAC source and provide a dual electronic thermo-
stat control system for pool/spa combinations or
preheat convenience.
The LX and LT Low NOx heaters are specifi-
cally 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 applications.
In the LX and LT heaters, low NOx operation is
achieved through use of a special “premix” combustion
system. The operation of this type of system is af-
fected by fuel gas properties. As noted in the trouble-
shooting and maintenance sections of this manual,
adjustments may be necessary if the local gas supply is
of especially high or low heat content.
1.2 Consumer Information and Safety
The LX and LT Low NOx heaters are 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.
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.
