4. Prep Water: Maintaining Correct Water Chemistry & Safety

Improper use of spa chemicals may be dangerous and could damage your hot tub and its cover. Since this damage

is not covered by your warranty; it is extremely important to take precautions when using these products. Only

use chemicals and cleaning agents designed for spas. Damage resulting from the use of non-recommended chemi-

cals and/or cleaning agents is not covered under the warranty. Following the procedures in this guide will make the

maintenance and care of your spa simple and economical.

Avoid using any biguanide or copper-based algaecides with your spa. Use of these products is not recommended by

ThermoSpas and may void your warranty.

Proper Handling of Chemicals

1. Keep all chemicals out of reach of children.

2. Always keep lids on chemicals when not in use and store them in a cool, dry location away from

direct sunlight

3. Do not store chemicals within the interior of the spa’s cabinet.

4. Do not interchange caps or measuring scoops for different types of chemicals.

5. Do not smoke around chemicals. Some can emit highly flammable fumes.

6. In case of contact or if a chemical is swallowed, call a doctor or local Poison Control Center. If a doctor

is required, bring the chemical container with you so the doctor can determine the appropriate treatment.

7. Never use swimming pool chemicals in your spa. They may void your warranty.

8. Never mix chemicals or chemical solutions directly with each other.

9. Always add chemicals to water when mixing them. Never add water to chemicals.

10. When in doubt, call Customer Care.

Proper Procedure for Adding Chemicals

Proper water chemistry is essential to the safety of the user as well to the life of the spa components.

Improper water chemistry may cause skin irritation or facilitate the transmittal of disease. Proper water

chemistry is the sole responsibility of the spa owner. The costs incurred from injury or damage resulting from

improper water chemistry are not covered under the Thermospas, Inc. warranty.

1. Turn on all water pumps. This will insure the added chemical(s) will be rapidly dispersed throughout the tub.

Unless otherwise specified, all water pumps should run at least 10 minutes after a chemical treatment.

2. Remove a gallon or more of water from the spa and pre-dissolve the chemical. Pour the bucket with the dis

solved chemicals back into the spa. This procedure insures complete solubility.

3. Only add one chemical at a time. Unless otherwise specified always wait at least 10 minutes after adding

chemicals to your spa before adding more chemicals.

Note: Depending on the metals or mineral content of your tap water, one of the chemicals in the treatment may react to cause a dis-

coloration or formation of a precipitate. In this event you should not have to drain your hot tub. There are treatments to solve this prob-

lem. If you have any questions contact Customer Care.

Chemical Start-Up

Your Thermospa has been delivered with a chemical starter kit. This kit allows you to choose between two

different sanitizing systems, ThermoClear or Chlorine. The start-up procedure is the same for all spas

including those with Ozonators or ThermOzone.

Wait until water is heated to 80° F minimum

Adjust Alkalinity & pH:

Setting up your water is just as important as sanitizing. Maintaining a proper pH level is essential for proper

operation of a Hot Tub. Regardless of the sanitizing method used, improper pH can cause your sanitizer to dis-

sipate rapidly, increasing the risk of contamination. Two specific problems with pH are low pH and high pH. The

low pH condition can cause pipes, motors, and seals to corrode, heaters to fail and skin discomfort. High pH can

cause a condition called scaling, cloudy water and eye discomfort.

Step 1: Use Test Strips in Starter Kit

Installing Your Spa

Step 2: Check Alkalinity (Alkalinity should be between 80ppm and 120ppm)

If alkalinity is too low, premix 1oz. Ph/Alk Up with spa water and add back to the spa. Never add

more than 1oz at a time. Wait 20 minutes and retest if still too low, repeat until the proper range

is achieved.

If alkalinity is too high, premix 1 oz. Ph/Alk Down with spa water and add back to the spa. Never add

more than 1oz at a time. Wait 20 minutes and retest if still too low, repeat until the proper range

is achieved.

Step 3: Below 80 Add Alk/pH UP Premix 1 Ounce to 1 Gallon of Water From The Spa

Above 120 Add Alk/Alk Down Premix 1 Ounce to 1 Gallon of Water From The Spa

Step 4: Check pH 7.2 - 7.8

If pH is too low, premix

oz. Ph/Alk Up with spa water and add back to the spa. Never add more than

1oz at a time. Wait 20 minutes and retest if still too low, repeat until the proper range is achieved.

If pH is too high, premix

oz. Ph/Alk Down with spa water and add back to the spa. Never add

more than 1oz at a time. Wait 20 minutes and retest if still too low, repeat until the proper

range is achieved.

Step 5: Below 7.2 Premix 1/2 Ounces to 1 Gallon of Water From the Spa

Above 7.8 Premix 1/2 Ounce to 1 Gallon of Water From the Spa

When adjusting pH and Alkalinity, do not exceed 4 oz. per day.

Choose

ThermoClear Start-Up

ThermoClear is a mineral-bed technology, based on breakthrough advances that recreate nature’s own

process of purifying water. The ThermoClear Cartridge works in conjunction with the spa activator to

create a great alternative system to Chlorine or Bromine.

Step 1: Add 3 oz. Stain & Scale to the spa.

Step 2: Add

oz. Natural & Clear to spa water

Step 3: Install ThermoClear Cartridge into center of filter media. For filters w/handles, place in basket.

Step 4: Add 2 oz. of Spa Activator to the spa water

Chlorine Start-Up

Chlorine Sodium Dichlor is considered the most effective chemical sanitizer you can use in a spa. Features include,

less chance of staining because it is such a good oxidizer, pH neutral so it does not throw off your pH reading, and

it is highly soluble and fast acting. Use the ThermoClear cartridge for extra sanitation and less chemical use.

Step 1: Add 3 oz. Stain & Scale to the spa.

Step 2: Add

oz. Natural & Clear to spa water

Step 3: Install ThermoClear Cartridge into center of filter media

Step 4: Add 2 teaspoons of Chlorinating Granules to the spa water

Step 5: Wait 15 minutes and test chlorine level. Level should be between 1-3ppm, if not, add 1 teaspoon more.

Adjusting Hardness

Many areas of the country, especially those that have a municipal water source, tend to have soft water. Soft

water may cause instant foaming and staining. Staining occurs because water has a natural demand for min-

erals and it attempts to satisfy this demand through the most readily available sources: heating elements,

plumbing, etc. This corrosion is not only damaging to your equipment, but it also can stain your water and shell

surface. All hot tub water should be tested for hardness levels.

Adjusting the water’s hardness if required. If you have any questions or concerns please contact ThermoSpas

Customer Care prior to filling your spa.

Step 1: Get Hardness Strips

Step 2: Check Hardness According to Directions on Strip (100 - 200 Best, 200 - 400 Acceptable)

If Below 100

Step 3: Add 4 Ounces/100 Gallons of Liquid Calcium. Wait 30 minutes. Continue to Adjust Hardness.

If Above 400

Step 4: Drain

of the spa’s water and replace with distilled water. Distilled water may be purchased

at a pool water supplier. Continue to Adjust pH
