3D-3. Spring Start-up

To restart the heater in the Spring, have a profes- sional service technician reassemble the heater as follows:

1.Attach the copper tubing to the pressure switch and fill the loop with SAE 50, non-detergent oil (see Figure 21).

2.Tighten the drain plugs.

3.Turn on the main gas supply valve to the heater, outside the heater jacket.

4.Turn on the heater following the lighting instruc- tions found on the inside of the heater.

3E. Water Chemistry

Proper chemical balances are necessary for sanitary bathing conditions as well as ensuring your heater's long life. Be sure to keep your chemical levels within the values indicated in Table 7. Teledyne Laars does not warrant heat exchangers damaged by corro- sive chemical levels or excess dissolved solids in pool or spa water.

For spas, it is also necessary to perform water changes in addition to chemical treatment. It is recom- mended to change the spa water every 60 days for light usage and every 30 days if usage is heavy.

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.

Figure 21. Heater drain locations.

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 4°F (-16°C).

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
