Installation & Operation Manual
3.4.2.3 Water Changing
Zodiac Pool Systems, Inc. recommends changing of
spa water every 60 days if usage is light and every 30
days during heavy usage. Be sure to stabilize the water
chemistry after every water change.
3.4.2.4 Corrosion
The corrosive action of pool/spa water is increased by the
following:
• Low pH - acidity
• Low Total Alkalinity - bicarbonates
• Low Calcium hardness - soft water
3.4.2.5 Testing
Zodiac recommends that spa owners purchase a test kit
and use it regularly. A minimum kit is one which will
measure chlorine and pH levels.
The pool/spa owner will nd it helpful to have a qualied
professional technician perform more extensive chemical
testing and water changing on a regular basis.
3.5 Spa/Hot Tub Safety Rules
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 tub water temperature should never
exceed 104°F (40°C). A temperature of 100°F
(38°C) is considered safe for a healthy adult.
Special caution is suggested for young children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
3. Pregnant women beware! Soaking in water above
102°F (39°C) can cause fetal damage during the
rst three (3) months of pregnancy (resulting in
the birth of a brain-damaged or deformed child).
Pregnant women should stick to the 100°F (38°C)
maximum rule.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err
in regulating water temperatures by as much as
4°F (2°C).
5. Persons with medical history of heart disease,
circulatory problems, diabetes or blood pressure
problems should obtain their physician's advice
before using a spas or hot tubs.
6. Persons taking medications which induce
drowsiness, such as tranquilizers, antihistamines,
or anticoagulants should not use spas or hot tubs.
3.4.2.2 Saturation Index
PH, Total Alkalinity (TA), temperature, Calcium Hardness
and Total Dissolved Solids (TDS) play a role in whether
the water is either corrosive or scale forming. These
factors are combined in the Langelier Saturation Index,
which is a method for determining whether or not water is
properly balanced.
Saturation Index = pH + AF + CF + TF -12.1*
A-Factor=(AF), C-Factor=(CF), T-Factor=(TF)

5 = 0.7 5 = 0.9 32 = 0.0
25 = 1.4 25 = 1.0 37 = 0.1
50 = 1.7 50 = 1.3 46 = 0.2
75 = 1.9 75 = 1.5 53 = 0.3
100 = 2.0 100 = 1.6 60 = 0.4
150 = 2.2 150 = 1.8 66 = 0.5
200 = 2.3 200 = 1.9 76 = 0.6
300 = 2.5 300 = 2.1 84 = 0.7
400 = 2.6 400 = 2.2 94 = 0.8
800 = 2.9 800 = 2.5 105 = 0.9
A saturation index of 0 is perfectly balanced
A negative saturation index has corrosive tendencies
A positive saturation index has scaling tendencies
A saturation index of +0.3 or -0.3 is ideal
*-12.1 should be changed to -12.2 if Total Dissolved Solids (TDS)
measure at 1,000 ppm or greater
Table 8. Water Saturation Index
The practice of putting tablet-based sanitizer in the
skimmer basket can produce heavily chlorinated water
with very low pH. If this comes in contact with metal
parts of the heater it can cause serious damage. Practices
like this should be discontinued.
If acidic conditions are present, there could be signs of
metal in the pool water that could cause staining on the
oor of your pool. This might manifest itself in the form
of brown stains on the nish of your pool bottom or pool
water discoloration. Your local pool dealer can test for
metals in your water or can provide you with a test kit.
Every effort should be made to maintain the water balance
of your pool or spa in the proper range. Ignoring this very
important component of your pool’s water chemistry can
make the water less enjoyable to bathe in and result in
permanent damage to your heater and/or complete failure
of individual components.
Zodiac Pool Systems does not warrant heat exchangers
damaged by corrosive water issues or from the build-up
of calcium in the heater’s heat exchanger. Any questions
regarding proper water balance can be directed to our
product support line at Zodiac® or to your local pool dealer.
