Maintenance
•
At least once a day wipe down interior surfaces and knobs. Contaminate can get into the pass
thru while the dirty side door is open. Particles can float into the pass thru and settle on the
interior. If left uncleaned this contamination can then be transferred into the cleanroom.
•
If the pass thru doors feature polycarbonate or acrylic windows wipe them down lightly with
soft cleanroom wipes to avoid scratching. Verify that any cleaning chemicals used are
compatible the with window material before cleaning.
•
Once a year check that the pass thru is securely mounted. All hardware, including perimeter
mounting screws should be securely fastened.
•
Verify that any cleaning chemicals used are compatible with cabinet materials.
