C. Use only your hand to turn the gas control on or off.
Never use tools. If you cannot change the ON/OFF
setting by hand, don’t try to repair it, call a qualified
service technician. Force or attempted repair may
result in fire or explosion.
D. Do not use this heater if any part has been under
water. Immediately call a qualified service technician
to inspect the heater and to replace any part of the
control system and any gas control which has been
under water.
E. Do not operate the pool heater unless the pool or
spa is properly filled with water.
F. Before operating the appliance for the first time or
after it has been off for an extended time, perform
the following checklist:
1. Remove debris or other articles from inside the
heater and the area around the heater and its
exhaust vent. Make sure the ventilation openings
are clear of debris or obstruction. For installations
in an enclosed space, make sure openings for
combustion and ventilation air are unobstructed.
2. Keep heater area clear and free from com-
bustibles, flammable liquids and chemicals.
3. Check that all water connections are tight.
4. Water must be flowing through the heater during
operation. Make sure that pool/spa is filled with
water and have pump operating. Check that water
flow is unobstructed from the appliance. When
operating for the first time or after an extended
shut-down, run filter pump for several minutes to
clear all air from the system.
SPA TEMPERATURE CAUTION
All safety rules recommended by the U.S. Consumer
Product Safety Commission should be observed when
using a spa or hot tub, including:
1. Spa or hot tub water temperatures 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
first three months of pregnancy (resulting in the birth
of a brain-damaged or deformed child). Pregnant
women should follow 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 temperature.
5. Persons with medical history of heart disease, circula-
tory problems, diabetes or blood pressure problems
should obtain their physician’s advice before using
spas or hot tubs.
6. Persons taking medications which induce drowsiness,
such as tranquilizers, antihistamines or
anticoagulants, should not use spas or hot tubs.
