Maintaining the PCS2 Equipment

P/N 85266-30, Manual revision: A
Pumps
The pump rotors should be removed from the well with the hexagonal head
wrench. Debris should be removed from the rotors and the pump wells on a
routine basis, as well as after any spills to contribute to efficient PCS2 operation.
For routine cleaning, the operator should:
Î
Remove the pump rotor from the housing, using the hexagonal head
wrench to remove the pump screw.
Î
Wipe the rotor and remove all debris from the rollers, using warm water
and lint-free cloth or gauze.
Î
Dry with lint free cloth (or compressed air, if available).
Î
Clean and dry the pump well using the same method.
Î
Ensure that all of the rollers spin freely and replace the pump rotor in the
well, aligning the cross pin in the rotor with the pump shaft.
Î
Replace and tighten the hexagonal head screw.
In the case of a fluid spill, the same cleaning method should be followed;
however, disinfectant cleaning solution should be used, followed by a clear water
rinse. The pump head should not be immersed in water.
Filter screens
The PCS2 device is equipped with filter screens on the bottom of the cabinet,
which eliminate dust from incoming cool air. The filters should be cleaned
routinely, especially if dust becomes visible on the screens.
To clean the filters, the operator should:
Î
Remove the retainer plates using a Phillips-head screwdriver.
Î
Remove the filter screens from the panel.
Î
Rinse the screens under running water - DO NOT use any cleaning
agents.
Î
Gently squeeze the screens to remove excess water.
Î
Place the screens on a clean, dry cloth and allow to dry completely.
Î
Reinsert the screens into the panel, ensuring that all openings are com-
pletely covered by the filter.
Î
Replace the retainer plates and tighten the screws.
Warning: To avoid electrical shock, the filter screen should be completely dry
before it is reinstalled on the PCS2 cabinet.
Barcode reader
The barcode reader window should be wiped using a lint-free cloth or gauze and
water, then dried. It should be cleaned whenever there is an accumulation of dust
or spilled fluid. For optimal cleaning, the operator should remove the protector
around the window and replace it once the window has been cleaned.
