Cartridge Change Maintenance Checklist Items
• Cartridge plume: Use a high-intensity flashlight or your headlamp to confirm that a
plume is streaming from the output port. If there is no plume:
• Check that the other output port is plugged. It should be.
• Check that the power is on and the appliance is running.
• Check that the o-rings on the air stem are in place and not cracked or broken.
Replace if necessary.
• If the dial is set to Program, switch it to 24/7 and check for a plume.
• If no plume, set the dial back to Program and change the cartridge.
• If still no plume, try another cartridge just to make sure. If no plume, replace the
appliance. (See
Changing an Appliance
below).
• Wipe the unit clean inside and out.

plume after following the procedure outlined above or there is any excessive noise
level, then the appliance must be replaced with a new one.

2. Using a Phillips screwdriver, unscrew the two bottom screws on the lower left
and right corners.
