3. Care and Maintenance
Cleaning
After each use, wipe the dryer with a damp
cloth. Clean each frame with mild soap and
water, rinse thoroughly with water and distilled
water, and allow to air dry. Never use abrasive
cleansers on any part. Do not expose the frame
to solutions or vapors of aromatic or haloge-
nated hydrocarbons, ketones, esters, alcohols
(over 30%), or concentrated acids (over 25%).
Changing the Gasket
If the gasket on the inner frame becomes inflex-
ible or no longer holds the gel stack tautly,
remove it and install a new gasket, stretching
it slightly around three sides and then rolling it
into place on the fourth.
Note: Never autoclave or heat
any component above 55 °C.
