Water Chemistry
(Corrosive water voids all warranties)
For your health and the protection of your pool equipment, it is essential that your water be chemically
balanced. The following levels must be used as a guide for balanced water.

** CR Superalloy can tolerate higher salt levels, and is even seawater resistant, but salt levels above 6000
PPM may cause damage to other components of the pool system, pool equipment or hardware.
• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing
• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water.

CAUTION
Elevated water temperature can be hazardous. The
U.S. Consumer Product Safety Commission has these
guidelines:
1. Spa water temperatures should never exceed
04°F (40°C). A temperature of 100°F (38°C) is
1
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.
Pregnant Women Beware!
3.
102°F (39°C) can cause fetal damage during the
first three 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.
Soaking in water over
CAUTION: Operating control and high limit are
NOT part of the Indirect Pool Heater. These items
must be supplied separately.
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
(2.2°C).
5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure
problems should seek a physician's advice before
using pools or hot tubs.
6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or
anticoagulants, should not use spas or hot tubs.
