Hyperthermia occurs when the internalbody temperature reaches a level several degrees abovethe normal body temperature of 98.6°F (37°C). Symptomsinclude dizziness, fainting, drowsiness, lethargy, and anincrease 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 drowning3.6 Swimming Pool Energy Savings TipsZodiac® suggests the following to help conserve fuel andminimize the cost of operating your pool heater withoutsacrificing comfort.1. Set the heater temperature control no higherthan 78°F (26°C). The American Red Crossmaintains that the healthiest water temperaturefor swimming is 78°F (26°C). Be certain you areusing an accurate pool thermometer because avariance of 4°, from 78 to 82°F (26 to 28°C), willuse as much as 40% more gas.2. Carefully monitor the water temperature of yourpool in the summer time, because heater usagecan be reduced due to warmer air temperatures.3. Find the proper setting on the pool heatertemperature control and use the TEMP-LOK todiscourage further adjustments.4. Set the filter time clock to start the pump noearlier than 6:00 AM during the pool heatingseason. This is the time when nightly heat lossstabilizes.5. If the pool is only going to be used on weekends,reduce the heater temperature control setting by 8or 10 degrees during the week. It should be resetto the 78°F (26°C) level before expected usage,keeping in mind to allow enough lead time for thewater to reach the desired temperature.6. During the winter shut down the heater byfollowing the lighting and shutdown instructionsin Section 3.1. When on vacation for longer thana week, make sure the heater is shut off at thetemperature control panel.7. Where possible, shelter the pool from prevailingwinds with well-trimmed hedges or otherlandscaping, cabanas, or fencing.8. Always use a pool cover when practical. Besidesproviding a valuable safety feature, a pool coverwill reduce heat loss, conserve chemicals, andreduce the load on filter systems.3.7 Seasonal Care3.7.1 Spring and Fall OperationDuring periods when the pool is only going to be usedonce 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 waterback up to swimming temperature.If the heater is not going to be used for a long period oftime, shut it down completely, following the instructionsin Section 3.3.2, Shutdown, or the lighting and shutdowninstructions posted inside the heater.3.7.2 WinterizingIf you don't plan to use the pool or spa over the winterand your area is subject to freezing temperatures, have aqualified professional technician perform the followingsteps to protect the heater:1. Shut off the heater's gas valve according to thelighting and shutdown instructions.2. Shut off the main supply gas cock outside theheater jacket.3. Completely drain the heater before the first frost.To drain the heater, remove the side panel, andremove the drain plug. See Figure 28.4. Grease the threads of the drain plug and return itto the manifold, but do not tighten.5. Disconnect the copper tubing from the pressureswitch fitting. See Figure 28.6. Cover the vent grille so that snow will notaccumulate in the combustion blower, where itmay freeze.
