REPAIR OR REPLACEMENT

NOTE

Prior to removal of old gasket material or insulation, cut the new replacement material to

size using the old item as a sample.

Remove as much old gasket or insulation material as possible by pulling or scraping it away

from the metal surface.

WARNING

Dry Cleaning Solvent is flammable, and its vapors can be explosive. Repeated or

prolonged skin contact or inhalation of vapors can be toxic. Use a well-ventilated area,

and keep away from sparks or flame. Use goggles, gloves, and apron when appropriate.

Soften and remove old adhesive and gasket residue, using dry cleaning solvent and a stiff brush.

To replace danger plate, use a drill bit slightly smaller than the diameter of the rivet being

removed.

Drill the rivets out and remove the old plate.

Align holes in replacement part and cover and install new rivets.

Minor dents and bent edges can be straightened using common sheet metal repair procedures.

Panels that are badly dented, bent, or punctured should be replaced.

Should touch up or refinishing be necessary, see WP0016.

Use only approved replacement material as specified in Chapter 8.

EMI gasket material specified for this unit is supplied with adhesive backing.

material.

Remove backing material from adhesive side and immediately press gasket in place. Be sure

that good edge-to-edge contact is made on the EMI gaskets.
