"Thermal Creep"

Cal Spas are designed with energy-efficient components and systems that are meant to sustain heat generated
by the equipment, which is then cycled back into the spa water. In hot weather or in situations where the spa is
set to extended run times, Thermal Creep may occur. Thermal Creep is a condition where the measured water
temperature can be higher than the set temperature. To manage Thermal Creep you may:
Vent your cover. This means placing a folded cloth about ¾" (2cm) thick under all four corners of the cover
before you lock the cover down.
Open your cover. Opening the cover at night will also quickly cool the water down if desired.
Open all air controls. Set your filtration cycles to run during the cooler times of the day or night.
Reduce the length of your filter cycles.
Visit your local dealer for additional guidance.
Since Thermal Creep only occurs in well-insulated hot tubs, it is not indicative of something that is wrong with
your spa or its equipment.

Possible Solutions
Automatic timer may have completed its cycle. Press JETS or JETS 1 button to start the
cycle again.
Pump may have overheated due to the vents on the equipment door being blocked.
Make sure the front of the spa is not blocked to allow air flow.
The pump motor may be defective. Contact your dealer for assistance.
A burning smell may be a sign of damage. Contact your dealer for service.
Pump may have over heated. Let it cool for an hour and try operating the spa for a
shorter time.
Power to the spa may be shut off. Turn on or reset the GFCI circuit breaker. If this does
not solve the problem, contact your dealer or a qualified spa technician.
