Section 7
Maintenance
The Model 282A is constructed and finished with materials that provide
long maintenance-free service. All that is normally required is a routine
cleaning of the exterior surfaces, oven shelf, and oven floor. Use a mild
detergent for this purpose. Additionally, all external line connections for
inert atmospheres should be checked for tightness on a weekly basis. The
oven door seal should also be visually checked for deterioration such as
cracks or loss of flexibility. A good seal is necessary to ensure proper
operation of the instrument.
Warning Secured access panels, covers, etc., should never be removed from
this equipment by anyone other than experienced service personnel.
Hazardous line voltages are present at various internally exposed points.
A separate manual section is included for qualified service personnel.
s
To replace the oven seal, remove the old seal and perform the following:
1. Clean the edge of the chamber with Xylene or similar.
2. Apply a thin bead of Dow Corning RTV-736 red silicone rubber
adhesive to the edge of the chamber.
3. Install gasket and close door.
4. Keep door closed for a minimum of 16 hours with 1-2 inches of
vacuum before using.
