18. Confirm Proper Airjet Operation
All Installations
NOTICE: Ensure that the area around the blower motor is free of sawdust, insulation, dirt, or other small
loose debris. Such material could clog the blower motor air ducts and reduce the air flow through the
blower motor.
NOTE: Please read these steps carefully before you operate your bath with airjets. Troubleshoot any
problems using the "Troubleshooting Procedures" section.
Keypad Operation
On/Off - Turns the blower motor on and off. Pressing the switch once starts the blower motor at a
midrange speed. Pressing the button again stops the blower motor. The blower motor automatically
stops after about 20 minutes of operation. The blower motor can be restarted by pressing the
On/Off button.
Purge Mode - Initiates the purge cycle manually. The purge cycle blows any residual water out of
the air channels after the bath has been drained. Pressing the button once starts the blower motor at
low speed. The blower motor stops automatically after about 2 minutes. Pressing the button again
before the cycle ends will stop the blower motor. Note that this product also has an automatic purge
cycle, which initiates about 30 minutes after the blower has stopped.
Increases Flow - Increases the air flow.
Decreases Flow - Decreases the air flow.
Preliminary Checks
Verify the water level is at least 2" (5.1 cm) above the top of the highest airjet, but at least 4" (10.2
cm) below the overflow. (This will help minimize water turbulence when testing the blower motor.)
Verify that the union connection at the check valve is securely hand tightened.
Verify that the screws are installed in the PVC air piping at the blower motor and at the check
valve.
Verify that cable ties support the air piping.
Verify that the blower motor is secure.
Verify that the keypad cable is securely connected at the user keypad and at the blower motor.
Confirm Air System Operation
Press the On/Off on the user keypad.
