SERVICE PROCEDURES
4
The material in this section of the manual is provided to allow for servicing
components of the sterilizer most likely to need attention. These procedures
are more advance than cleaning and replacing expendables (such as printer
paper and door seals). These procedures should always be performed by an
experienced, trained service technician.
WARNING - BURN HAZARD:
Before performing any clean-
ing or maintenance proce-
dures, allow sterilizer, gen-
erator (if applicable) and ac-
cessories to cool to room
temperature.
CAUTION - POSSIBLE
EQUIPMENT DAMAGE:
Sterilization of chloride-
containing solutions (e.g.,
saline) can cause chamber
corrosion and is not rec-
ommended by the manu-
facturer. If, however, chlo-
ride-containing solutions
must be processed, clean
the chamber after each use.
WARNING - BURN HAZ-
ARD: Failure to shut off
the steam supply when
cleaning or replacing
strainers can result in se-
rious injury.
4.1 Air Filter
Replacement
Refer to Figure 4-1 for location.
The purpose of the bacterial air filter is to filter incoming air. The system is
exposed to contamination whenever the filter or the air lines below the filter are
opened. Keep these components as clean as possible when servicing. The
bacterial air filter contains a replaceable filter cartridge, refer to Section 3.1,
Periodic Maintenance Schedule for frequency.
1. Remove the bowl from the filter body by loosening the retaining nut.
2. Remove the old filter element and discard.
3. Insert the new filter element (P129360-802) into the bowl.
4. Replace the bowl and tighten the retaining nut.
Refer to Figure 4-1 for location of strainers.
The strainers should be opened for cleaning after initial start-up and at least
twice a year thereafter (refer to Section 3.1,
Periodic Maintenance Schedule).
Accumulation of sediment and rust will reduce pressure and flow. In extreme
conditions, blockage may occur.
•
Disassembly
Shut off supply and vent pressure in line by running a short sterilizer cycle.
Abort the cycle when no pressure is present in the steam or water lines.
1.
Shut off water and steam supplies.
2.
Remove the hex plug and gasket.
3.
Pull strainer and screen from body.
4.
Scrape and polish all rust and residue from the strainer screen and
body. Use a wire brush or steel wool. Ensure all perforations are clear
by poking open with a wire. Replace screen if damaged, rusted or
corroded.
