12. One minute after the power is turned on, the spa will automatically begin its first one-hour filtration cycle (this
cycle may be interrupted if the Jet pumps are being turned on and off at the time). On two-pump models, Pump
2 will operate on high speed for the first minute of each filter cycle. If there is no jet action during the filter
cycle, repeat the pump priming steps described in Step 11 above. Once the Jets are working properly, turn the
power off and on again at the GFCI to reset the Start Time of the filtration cycle, which will begin one minute
after the power is turned on.
13. The spa will automatically filter itself twice each day. At the beginning of each filter cycle, the pump will run
on high speed for 5 minutes and then on low-speed for the remainder of the filter cycle. The second filter cycle
will begin twelve hours after the start of the first. The Filter Cycle light on the control panel will glow when a
filter cycle is running. To set a different start time for the cycles, you can turn the power to the spa off then back
on using the GFCI breaker at the time of day you want to cycle to start (the filter cycle always starts one minute
after the spa power is turned on
14. Now set the water temperature by pushing the UP/DOWN Buttons until the desired water temperature (called
the “Set Temperature”) appears in the Display Window. The spa will not allow the temperature to be set above
104°F (40° C). After a few seconds, the screen will revert to showing the current spa water temperature. The
spa will heat at the rate of 1° F (≅0.5°C) to 8° F (≅4° C) per hour. Whenever the temperature falls below the Set
Temperature, the spa will turn on the heater and run the pump at low speed to bring it back up to the Set
Temperature.
To confirm that the heater is on by checking that the Heat Indicator light on the control panel is
glowing.
15. Once the spa has begun heating, reinstall the equipment compartment panel removed in Step 2.
16. After completing the above steps, see the Water Care Guide (provided separately) to ensure proper water
chemistry.
17. Place the thermal cover on the spa to conserve energy and to keep it ready for use.
