Maintenance (contd.)

ENERGY SAVING TIPS

1. If possible, keep pool or spa covered when not in use.
This will not only cut heating costs, but also keep dirt
and debris from settling in the pool and conserve
chemicals.
2. Reduce the pool thermostat setting to 78° F. or lower.
This is accepted as being the most healthy temperature
for swimming by the American Red Cross.
3. Use an accurate thermometer.
4. When the proper maximum thermostat settings have been
determined, tighten the thermostat knob stopper.
5. Set time clock to start circulation system no earlier than
daybreak. The swimming pool loses less heat at this time.
6. For pools that are only used on the weekends, it is not
necessary to leave the thermostat set at 78° F. Lower
the temperature to a range that can be achieved easily in
one day. Generally, this would be 10° F. to 15° F., if pool
heater is sized properly.
7. During the winter or while on vacation, turn the heater
off.
8. Set up a regular program of preventative maintenance
for the heater each new swimming season. Check heat
exchanger, controls, burners, operation, etc.

SPRING AND FALL OPERATION

If the pool is being used occasionally, do not turn the
heater completely off. Set the thermostat down to 65° F.
This will keep the pool and the surrounding ground warm
enough to bring the pool up to a comfortable swimming
temperature in a shorter period of time.

WINTER OPERATION

WARNING
OPERATING THIS HEATER CONTINUOUSLY AT
WATER TEMPERATURE BELOW 68° F. WILL CAUSE
HARMFUL CONDENSATION AND WILL DESTROY THE
HEATER AND WILL VOID THE WARRANTY.
If the pool won't be used for a month or more, turn the
heater off at the main gas valve. For areas where there is no
danger of water freezing, water should circulate through the
heater all year long, even though you are not heating your
swimming pool. This heater should not be operated out doors
at temperatures below 0° F. for propane and -20° F. for
natural gas. Where freezing is possible, it is necessary to
drain the water from the heater. This may be done by opening
the drain valve located at the inlet/outlet header allowing all
water to drain out of the heater. It would be a good practice
to use compressed air to blow the water out of the heat
exchanger.

CHEMICAL BALANCE

POOL AND SPA WATER
Your MiniMax pool heater was designed specifically for
your spa or pool and will give you many years of trouble
free service provided you keep your water chemistry in
proper condition.
Three major items that can cause problems with your pool
heater are improper pH, disinfectant residual, and total
alkalinity. These items, if not kept properly balanced, can
shorten the life of the heater and cause permanent damage.
CAUTION
Heat exchanger damage resulting from chemical
imbalance is not covered by the warranty.
WHAT A DISINFECTANT DOES
Two pool guests you do not want are algae and bacteria.
To get rid of them and make pool water sanitary for
swimming - as well as to improve the water's taste, odor
and clarity - some sort of disinfectant must be used.
Chlorine and bromine are universally approved by health
authorities and are accepted disinfecting agents for bacteria
control.
WHAT IS A DISINFECTANT
RESIDUAL?
When you add chlorine or bromine to the pool water, a
portion of the disinfectant will be consumed in the process
of destroying bacteria, algae and other oxidizable materials.
The disinfectant remaining is called chlorine residual or
bromine residual. You can determine the disinfectant
residual of your pool water with a reliable test kit, available
from your local pool supply store.
You must maintain a disinfectant residual level adequate
enough to assure a continuous kill of bacteria or virus
introduced into pool water by swimmers, through the air,
from dust, rain or other sources.
It is wise to test pool water regularly. Never allow chlorine
residual to drop below 0.6 ppm (parts per million).
The minimum level for effective chlorine or bromine
residual is 1.4 ppm.
