7) Cleaning of Exterior Panels
Protect the exterior panels from attachment of dust and dirt. In general, dust attached to the exterior panels can be
removed only by wiping with a clean cloth wrung tightly after moistened with water.
To clean the front surface of the monitor screen, wipe with 10% diluted ethanol solution and then let the surface dry
naturally.
Wipe the reagent bottle rack door using glass cleaner and a soft cloth. If paraffin is attached, wipe it off with a cloth
moistened with Tissue Clear (or xylene).
Unless otherwise specified in this manual, never use solvent of any kind for cleaning, etc.

The paraffin oven and paraffin may be hot, so be careful not to burn yourself.
1. Open the door for the paraffin oven and remove the paraffin container to be cleaned.

9) Cleaning of the Retort
Clean the retort as necessary.
If buffered formalin is used, white precipitates may deposit in the retort. In this case, clean the interior walls
of the retort using a cloth moistened with cold or warm water. Thereafter, wipe dry the walls with alcohol and
let them dry.

2. Wear gloves and wipe the interior surface of the retort, lid gasket and gasket-contacting surface using a cloth
moistened with Tissue Clear (or a small amount of xylene).

To remove the strainer, turn the screw counterclockwise.
Clean the strainer using a brush or toothbrush.
Prevent foreign matters from getting in the strainer when
removing from the retort.
