Automatic Purge Cycle Operations
NOTE: The automatic purge cycle occurs after the bath is drained. It operates at low speed for about two
minutes to remove any residual water from the air channels.
If required, fill the bath to a level at least 2" (5 cm) above the top of the highest airjet.
Drain the bath.
When the water level drops below the level sensor probes, verify that the blower motor starts at low
speed.
After about two minutes, verify that the blower motor stops.
Manual Purge Cycle Operation
With the bath drained, rotate the ring on the user keypad to the purge cycle icon.
Press the "OK" button.
Observe that the blower motor starts in purge cycle to blow any residual water from the air
channels.
After the blower motor has operated for about two minutes, observe that the blower motor stops.
NOTE: If the bath is provided with chromatherapy, go to "Chromatherapy Operation (If Equipped)" to test
the lights. If not, the installation is complete.
