in swimming pools. Because of this, the chemical make-up of swimming pool chemicals is
usually quite different from that of hot tub chemicals. One example is that swimming pool
chemicals are not buffered so they can create havoc on the pH level of your hot tub water.
Q: Why are my pillows/headrests discolored or bleached out?
A: Headrests that are constantly submerged in spa water that is not properly treated with
chemicals may discolor. However, even if you have been performing your water maintenance
faithfully and correctly, the pillows will still naturally discolor over time. ThermoSpas does not
provide warranty coverage for bleaching or discoloration of spa pillows.
Q: I have done everything I could and my water is still messed up.
A: ThermoSpas offers free computerized testing of your water. If you reach the point of having
no luck with keeping your water in balance, and have tried draining and refilling your tub, you
can send us a sample of your hot tub water for analysis. Please contact our customer care
department 800.876.0158.
Q: What can I do if th pH is my spa is high (over 8.0) and will not come down?
A: Follow the steps below.
1. Turn on all pumps and add 1 ounce of ThermoSpas pH Down. Wait 15 minutes and retest
the pH.
2. If the pH is still out of the acceptable range add 1/2 ounce of pH down and retest after 15
minutes. Pumps should continue to run.
3. If the pH reading is still high, Step 2 may be repeated an additional two times.
4. Upon completion of Step 3, if the pH is still high, contact ThermoSpas Customer Care Dept.
Q: Why do I need any chemicals if Ozonators work so well?
A: Ozone is a powerful oxidizer and is considered to be 25 times more effective and works
100 times faster than traditional sanitizers like Chlorine or Bromine. However, ozone only
lasts about 20 minutes in a hot tub when the filtration pump shuts off. There are many
contaminants (i.e. algae, ammonia, nitrogen laden compounds, and bather wastes) that are
not controlled by ozone. Also, Ozonators have no affect on reducing the use of any other
chemical but sanitizers. Proper chemical use is recommended, take into consideration the
how ofter the hot tub is used and the number of bathers that use it.
Q: How do you prime a pump?
A: The best way to prime a pump is to put pump into high speed and loosen pump union just a
little bit to let the air escape from pump then tighten the union back up.
Q: What do I do if I have FLO on display?
A: (FLO) First make sure filters are clean and seated properly. Make sure water level is to
correct line on filter assay. Prime pump to free air pocket if any.
Q: How come 24-hour circulation pump turns on for 3 minutes then shuts off?
A: With the new addition of the 24-hour circulation pump they are set to turn on for 3 minutes
then shut off once the spa goes over the desired set temperature to eliminate heat gain from
pump.
Q: How do I change my filters if my pump circulation pump runs for 24 hours?
A: On some models of ThermoSpas it is almost impossible to change the filters while the pump
is on so the spa must be put into standby mode or power turned off at the circuit breaker.
