Pure Air® Auto-Dri™ Air Channels
J2 Auto-Dri™ Air Channels
The blower will operate for 20 minutes and then automatically shut off, unless power is manually turned off. In either
case, 20 minutes after the blower has shut off, it will turn ON for a one-minute drying cycle to blow out any water remain-
ing in the air system.
If the bath is used without the blower operating (showering or bathing without using the Pure Air
®
system), initiate the one-
minute drying cycle manually by use of the ON/OFF switch. Turn the switch ON and OFF again as you exit the bath and
the drying cycle will occur in 20 minutes.
J2 Daily Auto-Dri™ Cycle
To Activate: Holding the button for ve-seconds when the blower is off activates the daily Auto-Dri™ cycle. The blower
will start every day at the same time for one-minute. Once the daily Auto-Dri™ cycle is activated, the blower will come on
for one-second, turn off for two-seconds, come on for one-second and then turn off.
To Deactivate: Holding the button for ve-seconds when the blower is off deactivates the daily Auto-Dri™ cycle. When
the daily Auto-Dri™ cycle is deactivated, the blower will come on for one-second and then turn off.
J4 Auto-Dri™ Air Channels
The Auto-Dri™cycle is automatic and will reduce excessive accumulation of residual water in the air channels.
There are two Auto-Dri™ cycles: drain assisted Auto-Dri™ cycle and daily Auto-Dri™ cycle.
J4 Drain Assist
The Auto-Dri™ cycle is sensor assisted – two sensors (metal dials) are located near the drain of the bathtub. The sensors
detect the presence and absence of water in the bathtub.
To ensure effective and correct operation of the water sensors, it is important to keep them clean and free from block-
age or objects.
After bathing and following the emptying of the bathing well, the sensors detect a “no water” condition. A ve minute wait
time elapses and then the blower is activated. The blower will cycle through a range of speeds for 2 ½ minutes, during
which either 2 or 3 indicator lights will ash at various speeds.
• The Auto-Dri™ cycle will engage even if the blower is not used during bathing.
• The cycle may initiate more than once if the sensors become wet during any part of the Auto-Dri™ operation or during
routine cleaning of the bathtub. This is normal and does not require attention.

J4 Daily Auto-Dri™ Cycle
Each day, the blower will automatically activate a daily Auto-Dri™ cycle. The blower will operate for one minute on high
power, followed by 15 seconds at ½ power.
To set Auto-Dri™ cycle time: Wait until the time that you desire the daily Auto-Dri™ cycle to activate. With the blower off,
press and hold the plus button for ve seconds. To conrm that you have set the time, the blower will cycle between on
and off two times in a 4 second span.
To cancel daily Auto-Dri™ cycle: With the blower off, press and hold the plus button for ve seconds. To conrm that you
have cancelled the Auto-Dri™ cycle , the blower will come on for 1 second and then stop.
You must set the daily Auto-Dri™ cycle upon installation; the default is no pre-set daily Auto-Dri™ cycle.
If a power failure occurs, the system will default to no daily Auto-Dri™ cycle.
