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:
• Unawareness 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
3.6 Swimming Pool Energy Savings Tips

suggests the following to help conserve fuel and
minimize the cost of operating your pool heater without
sacricing comfort.
1. Set the heater temperature control no higher
than 78°F (26°C). The American Red Cross
maintains that the healthiest water temperature
for swimming is 78°F (26°C). Be certain you are
using an accurate pool thermometer because a
variance of 4°, from 78 to 82°F (26 to 28°C), will
use as much as 40% more gas.
2. Carefully monitor the water temperature of your
pool in the summer time, because heater usage
can be reduced due to warmer air temperatures.
3. Find the proper setting on the pool heater
temperature control and use the TEMP-LOK to
discourage further adjustments.
4. Set the lter 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
stabilizes.
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. It should be reset
to the 78°F (26°C) level before expected usage,
keeping in mind to allow enough lead time for the
water to reach the desired temperature.
6. During the winter shut down the heater by
following the lighting and shutdown instructions
in Section 3.1. When on vacation for longer than
a week, make sure the heater is shut off at the
temperature control panel.
7. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other
landscaping, 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 lter systems.
3.7 Seasonal Care
3.7.1 Spring and Fall Operation
During periods when the pool is only going to be used
once in a while, turn the temperature control to the "MIN"
setting. This prevents the pool from becoming "chilled,"
yet still requires the least amount of time to raise the water
back up to swimming temperature.
If the heater is not going to be used for a long period of
time, shut it down completely, following the instructions
in Section 3.3.2, Shutdown, or the lighting and shutdown
instructions posted inside the heater.
3.7.2 Winterizing
If you don't plan to use the pool or spa over the winter
and your area is subject to freezing temperatures, have a
qualied professional technician perform the following
steps to protect the heater:
1. Shut off the heater's gas valve according to the
lighting and shutdown instructions.
2. Shut off the main supply gas cock outside the
heater jacket.
3. Completely drain the heater before the rst frost.
To drain the heater, remove the side panel, and
remove the drain plug. See Figure 28.
4. Grease the threads of the drain plug and return it
to the manifold, but do not tighten.
5. Disconnect the copper tubing from the pressure
switch tting. See Figure 28.
6. Cover the vent grille so that snow will not
accumulate in the combustion blower, where it
may freeze.
