Care and Maintenance

Cleaning

NOTE Never autoclave or heat any component above 55 °C.

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 halogenated hydrocarbons, ketones, esters, alcohols (over 30%), or concentrated acids (over 25%).

Changing the gasket

If the gasket on the inner frame becomes inflexible 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.

Changing fuses

NOTE Fuses protect equipment by disconnecting loads too large for the instrument's circuit design. Replace fuses only with identical fuse values.

115 V~ model: one F 12A 250V 3AG

230 V~ model: two T 6.3A 250V, 5 x 20 mm

1.Caution! Set the power switch to off and unplug the power cord before replacing the fuse.

2.Insert a small flat-blade screwdriver into the slot on the fuse module, depress slightly, and turn it ¼-turn counterclockwise. The spring-loaded module cap will loosen and you can then pull the cap/fuse holder out.

3.Pull the fuse out of its holder and inspect. If the fuse element is burned or broken, replace the fuse with an identical type. If the fuse appears to be intact, check it with a multi-meter. (A reading of 1 Ω or less indicates the fuse is still usable.)

4.Insert the fuse into the holder and then insert this assembly back into the unit. Seat the module by inserting the screwdriver into the slot, pressing gently, and turning the cap ¼-turn clockwise.

5.230 V~ model: Repeat steps 2 to 4 for the second fuse.
