Operating Instructions
A door interlock feature prevents cross contamination by allowing only one door
to be opened at a time. Doors can be opened one at a time when green light is
on.
Load end control will energize load end doors only. Unload end control will
energize unload end doors only.
NOTE: It is possible to bypass the interlock system in Service Mode (see
Section 4 of Maintenance Manual P764330-842), if opening of both doors at the
same time is more practical for operator.
NOTE: If operator chooses to deactivate interlock feature, pressing
DOOR
CLOSE
or
DOOR OPEN
touch pads on either side of washer will automatically
open or close doors on both the load and unload side.
1. Lock building electrical supply disconnect switch on
OFF
position and close
unit air supply valve before opening doors manually. If not, when the power
returns, doors could close automatically.
2. Wearing gloves, slide fingers between doors and slowly push the doors
apart.
NOTE: If operator is inside wash chamber during a power failure, it is possible
to exit through the Emergency Exit Safety Doors or by opening the doors
manually.
