10.4 Door Seal
Replacement
Procedure
Refer to Figures 10-2 and 10-3.
This procedure should be performed by a qualified service
technician. If door seal requires replacement, perform the following:
1. Allow sterilizer chamber and end frame to cool to room
temperature.
2. Open sterilizer door.
3. Use flat tool with rounded edges (such as a tongue depressor or
non-serrated table knife) to pry and twist one section of the seal
partially from the groove. Refer to Figure 10-2.
4. Grasp the raised section of the seal and pull the remainder from
the end frame groove.
5. Examine the end frame groove for debris or residue. Clean if
necessary.
6. Install new seal as follows:
NOTE: Ensure that lot data molded into rear of seal (refer to
Figure 10-3) is at the bottom of the groove.
• Do not use a sharp instrument to install the seal.
• Do not stretch the seal.
a. Align right and left reference indicators with drill point
reference marks in seal groove, align top and bottom
indicators with the drill point reference marks in seal groove.
NOTE: Reference indicators are located inside the rear groove of
door seal, at the middle of each side (refer to Figure 10-4).
b. Press seal in at each reference point with fingertips.
c. Press seal in at each corner with fingertips.
d. Press remainder of the seal into end frame groove.
7. Test installation.
a. Attempt to close the door. If the door sticks or will not fully
close at any point in its travel, check to make sure 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 frame 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.
At the end of the cycle, ensure seal has retracted fully into
the groove.
WARNING – BURN HAZARD:
Allow sterilizer and
accessories to cool to room
temperature before
performing any cleaning or
maintenance procedures.
