10.3 Clean Jacket
Steam Strainers
The strainers should be opened for cleaning after initial start-up and
at least twice a year thereafter (refer to Table 8-1. Preventive
Maintenance Schedule). Accumulation of sediment and rust will
reduce pressure and flow. In extreme conditions, complete blockage
may occur.
Shut off supply and then vent pressure in line by running a short
sterilizer cycle. Abort the cycle when no pressure is present in steam
or water lines.
Disassembly
1. Assure water and steam lines are still shut off.
2. Remove hex plug and gasket.
3. Pull out strainer screen from body.
4. Scrape and polish all rust and residue from strainer screen and
body. Use a wire brush or steel wool. Be sure that all perforations
are clear. Replace screen if damaged, rusted or corroded.
Reassembly
1. Insert screen into strainer body. Ensure that no dirt or other
particles remain in strainer body.
2. Replace and tighten hex plug. Use a new gasket if necessary.
3. Make certain that all pipe connections are tight after assembly.
10.4 Door Seal
Replacement
Procedure
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 non-serrated table
knife) to pry and twist one section of the seal partially from the
groove. Refer to Figure 10-1 for 660 x 660 mm (26 x 26”)
sterilizers, or Figure 10-2 for 660 x 950 mm (26 x 37.5”)
sterilizers.
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 10-1 or Figure 10-2) 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.
