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 IBCL). 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. Ensure 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

NOTE: Floorloading sterilizers are designed with a seal configuration
different from the 26 x 26" (660 x 660 mm) and 26 x 37.5"
(660 x 953 mm) sterilizers. Refer to SECTION 10.5,

knife) to pry and twist one section of the seal partially from the
groove. Refer to Figure 10-1 for 26 x 26” (660 x 660 mm)
sterilizers, or Figure 10-2 for 26 x 37.5” (660 x 953 mm)
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.
