Electrical Tests
Electrical grounding tests should be made to assure that all exposed metal surfaces
of the cabinet are grounded.
Equipment
0-1 ohm full scale ohmmeter
Testing
1. Disconnect the cabinet from the power source.
2. Connect one lead of the ohmmeter to the ground pin on the power cord plug.
3. Touch the other lead to the ground pin on the convenience outlet, stainless
steel work deck, viewscreen frame, and several of the exposed screw
fasteners on the front of the cabinet.
4. The ground resistance should be less than 0.15 ohms at any test location.
XIV. SUGGESTED WORKING PROCEDURES
Cabinet Operation
After the cabinet has been properly installed and certified, it is ready for use. The
three switches on the control panel operate the cabinet blower system, fluorescent
lights, and convenience outlet separately.
Surface Decontamination
To disinfect the work area before use, turn the blower system "ON," raise the
viewscreen and secure it with the bead chain holder, wipe the stainless steel and all
work area components, including the inside of the viewscreen, with a fast-drying,
non-corrosive disinfectant. Remove the two screws located at the two front corners
of the perforated diffuser grille above the work area. Carefully remove the grille and
clean it on both sides. Do not attempt to clean the bottom of the HEPA filter since
any contact with the filter surface may cause damage and contamination leakage.
After the cabinet is turned “OFF,” the work surfaces should be cleaned with a
disinfectant. The work tray, front air grille, and work tray support/rear air grille can
be removed to facilitate the clean up of any spillage.
An optional UV light accessory (#22557) can be used for interior work surface
decontamination. The UV light accessory fits into the face opening and the power
and switching function is supplied from the convenience outlet within the cabinet.
