Cover Gasket Replacement Instructions
Remove the reservoir cover. While looking at the top of the unit, reference Figure A and B to determine
which humidifier tank style you have.
Figure A Installation
Fit the gasket around the entire lip of the tank opening. Cut the gasket 1/8” longer than required, this will
ensure proper fit when the cover is clamped back on. Slide the gasket onto lip of tank around the entire
perimeter, and seal the ends together with a small amount of silicone.
Figure B Installation
Fit the gasket around the entire lip of the tank opening. Cut the gasket 1/8” longer than required, this will
ensure proper fit when the cover is clamped back on. Slide the gasket onto lip of tank around the entire
perimeter. Notch only the bottom flap of the gasket (reference Fig. C) in the corners of the tank. Seal the
ends together with a small amount of silicone.
