To AdMInISTEr SpA WATEr CHEMICAlS:

1. Fold back the spa cover. 

2. Push the JET button twice to activate the jet pump’s high speed mode.

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 siding.

4. After ten minutes, shut off the jet pump and close and lock the cover to complete the procedure. 

Risk of Drowning:

 Never leave an open 

spa unattended!

WaRNING: 

High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the 

recommended range before using the spa.

Note: 

After administering a super chlorination treatment or non-chlorine shock to your spa, leave the cover open for a minimum of twenty 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’s 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 Manufacturing corporation recommends using the 

CleaN SCReeN

pre-filter when 

filling the spa with water. Always fill the spa through the filter compartment.

B. The 

CleaN SCReeN

 pre-filter is designed to remove unwanted contaminants such as rust, dirt, detergents and algae as well as iron, copper 

and magnesium from the fill water. dissolved minerals and metals such as lead and calcium are not removed.

c.  Instructions are included with the 

CleaN SCReeN

 pre-filter. When the spa is filled, proceed to the start-up and Refill Procedures on page 15.

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 FReSHWateR  pH/alkalinity Up or 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 

FReSHWateR pH/alkalinity Down or 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 50-150 ppm.

B.  CH 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 

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 using the Vanishing act 

®

 calcium remover available from your Hot Spot  dealer. 

[Additionally, a stain and scale inhibitor, 

such as 

FReSHWateR

 stain and scale defense, should be added to the spa water, according to label instructions.]

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 cH is within the recommended range, proceed to the next step.
