If the door seal requires replacement, perform the following:
1. Use a tongue depressor or similar non-metal tool to pry and twist one section
of the seal from the groove. Refer to Figure 3-4a.
2. Grasp the raised section of the seal and pull the remainder from the end-ring
groove.
3. Examine the end ring groove for debris or residue. Clean if necessary.
4. Install new seal as follows:
NOTE: When replacing the door seal, note the following:
1) Ensure date information molded into rear of seal (refer to Fig. 3-4b) is at the
bottom of the groove.
2) Reference indicators are located inside the rear groove of door seal, at the
middle of each side (refer to Fig. 3-4b).
•
Do not
use a sharp instrument to install the seal.
•
Do not
stretch the seal.
a. Align right and left reference indicators with the screws attaching the end
frame to the support stand, align top and bottom indicators with the ports
in the top and bottom of the end ring frame.
b. Press seal in at each reference point with fingertips.
c. Press remainder of the seal into end-ring groove, starting at the corners.
5. Test installation.
a. Attempt to close the door. If the door jams or sticks at any point in its travel
check to ensure the seal has been fully pressed into the groove.
b. Run a shortened test cycle to determine if the door seals adequately. If
steam leaks from around the door or the seal, abort the cycle and examine
the seal to ensure it has been properly seated in the end-ring groove. Once
re-seated, run another test cycle. If the door fails to seal following the
second test, another problem may exist. Contact your supervisor before
using the sterilizer further.
c. At the end of cycle, ensure seal has retracted fully into the groove.
