4. DECONTAMINATION OF THE MACHINE AND PARTS
4.1 WHEN TO DECONTAMINATE THE WASHER?
Special care must be taken to protect users and maintenance personnel from coming in contact
with the chemicals, temperatures, and hazardous materials that may be used in this machine. This
can occur due to a wash cycle being prematurely interrupted by opening the door, turning off
power, or an alarm condition.
If the door has been inadvertently opened, the machine should be allowed to cool down for one
hour then the door should be shut and the cycle restarted. If the power has been inadvertently
turned off, it should be turned on and the cycle restarted.
If the washer has stopped due to an alarm condition that requires a maintenance technician, the
maintenance technician must decontaminate the machine before performing the repairs.

Remove the Waste Water Flexible emptying hose from the standpipe and place it in a large
containment sump (that can hold 14 liters (3.7 gallons)) with a top edge no more than 100 mm (4
inches) above the floor. This will siphon water from the basin into the containment sump.
Replace the Waste Water Flexible emptying hose into the standpipe.
Remove the 2 basin filters and use an external pump to remove the remainder of the water from
the bottom of the chamber. Replace the 2 basin filters.
Remove the necessary side panel(s) in order to gain access to the components that need to be
repaired or replaced.
Perform the repairs by replacing the parts in the same manner by which they were installed in the

any modification or calibration by maintenance personnel.
