Hi-E2
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
3F. Swimming Pool Energy Savings Tips
Jandy suggests the following to help conserve
fuel and minimize the cost of operating your pool
heater without sacrifi cing 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) is. Be certain you
are using an accurate pool thermometer, because
a variance of 4 degrees, 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 fi 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 3A. 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 fi lter systems.
3G. Seasonal Care
3G-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 3C-2, Shutdown, or the lighting
and shutdown instructions posted inside the heater.
3G-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 qualifi ed 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 fi 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 fi tting (see Figure 28).
6.
Cover the vent grille so that snow will not
accumulate in the combustion blower, where it
may freeze.
To reactivate the heater in the spring, have a
qualifi ed professional technician reassemble the heater
as follows:
1.
Attach the pressure switch fi tting to the copper
tubing (see Figure 28).
2.
Tighten the drain plugs in the headers.
3.
Clean the condensate drainage system and
condensate trap.
4.
Replace the combustion air fi lter.
5.
Uncover the vent grille.
6.
Turn on the main supply gas cock outside the
heater jacket.
7.
Turn on the heater according to the lighting and
shutdown instructions inside the top cover.
