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.

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 and regular gasketing specified for this unit are supplied with adhesive

backing.

Cut gasket to size. Be sure that EMI gasket corners are mitered so that good continuous edge

contact is made.

Be sure that surface to which gasket is to be applied is clean and free of paint and old adhesive

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.

INSTALLATION

Using a screwdriver, socket and ratchet, attach each EMI screen to the frame with four screws

and locknuts. Be sure that hardware is tightened evenly, and that there are no gaps between the

EMI screen and frame.

Using screwdriver, install the assembled EMI screens and frame to the housing with twenty

screws.
