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: Do hot tubs with Ozonators require less chemicals?
A: Yes. If your hot tub includes an Ozonator, you can reduce your use of both sanitizer and activator by
approximately 50%. For example, hot tubs with Ozonators require a bromine reading of only 1 to 3 ppm.
Each week, add only 2 oz. of Bromide Salts (sanitizer) and 1 oz. of Spa Activator (activator) after each use.
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.
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: (Flashing 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. (Solid FLO) You need to make an adjustment on the
pressure switch itself with power to spa, turn to calibration wheel ? clockwise to full turn. Switch is very
sensitive and sometimes needs slight adjustment.
Q: How do I get LOC off my control panel? It’s flashing (LOC) 1900D.
A: To remove LOC off panel for 1900D, first press up temperature arrow immediately followed by the
light button.
Q: How do I get LOC off my control panel? It’s flashing (LOC) 2000D.
A: To remove LOC off panel for 2000D, first press temp arrow and then mode.
Q: What is dr?
A: dr means there is in adequate water detected in the heater and on 3rd occurrence of this control panel
will display dr4 or dry. RESOLVE: Prime pump and make sure all t valves are up before contacting service
for further trouble shooting.
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 (please refer to owners manual).
Q: What does O3 mean on the control panel?
A: O3 simply means if you have an ozonator in your spa it is on if you do not have one this is an option please
call the service department if you wish to order one or to have one installed.
NOTE: If O3 doesn’t show up on your control panel this doesn’t mean your ozonator isn’t working O3 shows up
periodically and ozonator works even when light isn’t on.
Q: I am going away on vacation, should I winterize?
A: Winterizing your spa while your on vacation is not only smart but it could save you operation cost. You won’t
have to have someone check it every 24hrs. Also if the power goes out or spa freezes this will eliminate any
freeze damage which isn’t covered under any warranty. NOTE: It is the customers responsibility to keep the spa
from freezing.
Q: Why is my pump always running?
A: a. If your spa has a circulation pump it is set to run 24/7, unless the spa temperature goes 3 degrees above
the set temperature. b. Heater malfunction, please contact the service department.

Q: How do I troubleshoot an instant tripping breaker?
A: The proper way to troubleshoot is first turn GFCI breaker off. Access spa pac and unplug all components
except for light. All water pumps, blowers, and ozonator if spa has one. Then turn GFCI breaker back on. If
breaker does not hold the only components that are still connected is the heater since heater wires are
inside spa pac. If breaker does hold one at a time replug in components and which ever one is failing will trip
breaker when you plug it in. At this point second, third, forth pump can be left unplugged. Also if blower
or ozonator is causing the problem, they can be left unplugged. Only spas heater and primary pump are
necessary to maintain heat and filter cycle.
Q: I have no pressure to one of my seats, what is the problem?
A: a. Try your whirlpool jet or top side diverter valve. b. Your jets may be in the closed position. Most of the
jets in your spa have an outer ring that turns to the left and right. This will open or close the jets.
Q: My pump isn’t working properly and it doesn’t seem to be pushing any water at all, what can I do?
A: a. Open your panel and find your pump. Chances are a gate valve might be closed, which will shut the
pump off. Open the valve by lifting the handle. b. Your pump may need to be primed. Open the hose spigot
(if applicable) or open the union connection slightly to bleed the air out of the line.
Q: I need a service appointment, but I’m only available after 5PM. Is there any way that you can come later?
A: If your spa and circuit breaker are outdoors, you don’t need to be home. We can easily set up an appoint-
ment and you will not need to lose time at work. Our technicians work to be sure that all of their scheduled
stops are completed to satisfaction every day, and that includes scheduling time of their stops.
Q: I have a brand new hot tub and it is leaking. I need a service man right away.
A: Firstly, there are a few things we will ask you to do. Describe that area of the spa where the leak seems to
be coming from. Open one of the panels in that area and check your pumps union connections. If you have a
loose union, simply tighten the connection and the leak should stop. This is a part of your spa start up and
is the responsibility of all of our customers to make sure that this is done.
