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
1.2.2 Swimming Pool Energy Saving Tips
Waterpik Technologies offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without
sacrificing comfort.
1.
The American Red Cross recommends a maxi-
mum water temperature of 78°F (25°C). Use an
accurate pool thermometer. A difference of 4F°
(2°C) , between 78°F and 82°F (26°C and 28°C),
will use as much as 40% more gas.
2.
Carefully monitor the water temperature of your
pool in the summertime. You can reduce heater
usage due to warmer air temperatures.
3.
Find the proper setting on the pool heater
temperature control and use the locking ring to
discourage further adjustments. (LT only).
4.
Set the pump time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat loss
balances.
5.
If the pool is only going to be used on weekends,
reduce the heater temperature control setting by
8 or 10 degrees during the week. Reset it to the
78°F (25°C) level a day or so before you plan to
use the pool.
6.
During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found on the inside of
the heater.
7.
Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other land-
scaping, cabanas, or fencing.
8.
Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on filter systems.
1.3 Warranty
The LX and LT Low NOx heaters are sold with
a limited factory warranty. Details are specified on the
back cover of this manual.
Make all warranty claims to an authorized Jandy
representative or directly to the factory. Claims must
include the heater serial number and model (this
information can be found on the rating plate), installa-
tion date, and name of the installer. Shipping costs are
not included in the warranty coverage.
The warranty does NOT cover damage caused
by improper assembly, installation, operation or field
modification. Also, damage to the heat exchanger by
corrosive water is NOT covered by the warranty. See
Section 8.1 for maintaining proper pool water chemis-
try.
NOTE: Keep this manual in a safe place for
future reference when inspecting or servicing
the heater.
1.4 Codes and Standards
The LX and LT Low-NOx pool and spa heaters
are design certified by CSA (Canadian Standards
Association) as complying with the latest edition of the
"Standard for Gas Fired Pool Heaters", ANSI Z21.56
in the USA and CAN-4.7 in Canada.
All Jandy heaters must be installed in accordance
with the local building and installation codes as per the
utility or authorities having jurisdiction. All local codes
take precedence over national codes.
In the absence of local codes, refer to the latest
edition of the following national codes for installation:
1.
In the United States, "The National Fuel and Gas
Code", NFPA 54/ANSI Z223.1. Specifically,
refer to Part 7, "Venting of Equipment".
2.
In Canada, "Natural Gas and Propane Installation
Code", CAN/CSA-B149.1.
The LX and LT Low NOx pool and spa heaters
exceed the requirements of energy conservation
regulations such as those in California, Hawaii, New
York, Oregon and other states which require that a
pool heater have intermittent ignition. In addition, the
natural gas models of this heater comply with both the
California South Coast Air Quality Management
District's (SCAQMD) rule 1146.2 and the Title 30,
Texas Administrative Code, Chapter 117, Section
117.465 for Nitrogen Oxide (NOx) emissions.
