3F. Spa/Hot Tub Safety Rules

WARNING

The following “Safety Rules for Hot Tubs,” recommended by the U.S. Consumer Product Safety Commission, should be observed when using the spa.

1.Spa or hot tube 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 subse- quently 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) maxi- mum.

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 4F° (2C°).

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.

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 drown- ing

3G. Swimming Pool Energy Saving Tips

Waterpik Laars offers the following recommen- dations to help conserve fuel and minimize the cost of operating your pool heater without sacrificing com- fort.

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° (3C°) , between 78°F and 82°F (25°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 tem- perature control and use the TEMP-LOK to discourage further adjustments.

4.Set the filter 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.
