HOW TO ADD CHEMICALS TO THE WATER
IMPORTANT: All spa water chemicals, including granulated dichlor, MPS, granulated pH increaser or decreaser, granulated total
alkalinity increaser, liquid stain and scale inhibitor, and liquid defoamer must always be added directly into the filter compartment while
the jet pump is running in its high speed mode, and it must run for a minimum of ten minutes.
To Administer Spa Water Chemicals:
1. Fold back the cover. Carefully remove and set aside the filter compartment cover.
2. Push the CLEAN soft button (on home screen) to turn on the jet pump.
3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on
your hands, in your eyes, on the spa shell surface, or on the spa cabinet.
4. Replace the filter compartment cover. After ten minutes, the jet pump will automatically shut off to complete the procedure. Close and secure
the cover. Risk of Drowning: Never leave an open spa unattended!
IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT” NOTE: After administering a super chlorination
treatment or non-chlorine shock to your spa, leave the cover open for a minimum of 20 minutes to allow the oxidizer gas to vent. A high
concentration of trapped oxidizer gas which may exist as a result of the shock treatment (not daily sanitation) may eventually cause
discoloration or vinyl degradation to the bottom of the cover. This type of damage is considered chemical abuse and is not covered under the
terms of the limited warranty.

SPA WATER MAINTENANCE PROGRAM
Each step in your water maintenance program is dependent on the completion of the previous steps. Omitting a step, or failing to reach
the recommended range may cause an imbalance in your water chemistry. Unbalanced water chemistry can damage the spa, and its
components, as well as cause discomfort for the user.
FILLING THE SPA WITH WATER
A. To prevent contaminants from entering the spa, Watkins recommends using the FreshStart
®
10,000
pre-filter when filling the spa with water. Always
fill the spa through the filter compartment.
B. The FreshStart
10,000
pre-filter is designed to remove unwanted contaminants such as rust, dirt, detergents, and algae from the fill water.
Dissolved minerals and metals such as lead, calcium, copper, and iron are not removed.
C. Instructions are included with the FreshStart
10,000
pre-filter. When the spa is filled, proceed to the Start-Up and Refill Procedures section.
BALANCING THE TOTAL ALKALINITY (TA)
A. The recommended Total Alkalinity (TA) for your spa water is 40-120 ppm.
B. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA is
referred to as the water’s “pH buffer”. In other words, it’s a measure of the ability of the water to resist changes in pH level.
C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or scaling of the spa components.
Low TA can be corrected by adding Hot Spring FreshWater
®
pH/Alkalinity Up (sodium hydrogen carbonate).
D. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult to bring down. It can be lowered by adding Hot Spring
FreshWater pH/Alkalinity Down (sodium bisulfate).
E. Once the TA is balanced, it normally remains stable, although the addition of more water with a high or low alkalinity will raise or lower the TA
reading of the water.
F. When the Total Alkalinity is within the recommended range, proceed to the next step.
BALANCING THE CALCIUM HARDNESS (CH)
A. The recommended Calcium Hardness (CH) level for your spa is 100-150 ppm.
B. Calcium Hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the corrosive nature of the spa’s
water. That’s why calcium-low water (commonly known as “soft” water) is not recommended. It is very corrosive to the equipment, and can
cause staining of the spa shell. If the calcium level is too low, we recommend using Hot Spring FreshWater Calcium Increaser to bring the
calcium hardness level to within the recommended range.
C. If the CH is too high (commonly known as “hard” water), formation of scale on the spa’s shell surface and equipment can result. CH can be
decreased by dilution – a mixture of 75% hard and 25% soft water will be a good starting point. If soft water is not available, or practical
for you, a stain and scale control such as Hot Spring
®
FreshWater
®
Stain and Scale Defense should be added to the spa water, according to
instructions on its label.
D. Once the CH is balanced, it normally remains stable, although the addition of more water with a high or low calcium content will raise or lower
the CH reading of the water.
E. When the Calcium Hardness is within the recommended range, proceed to the next step.
