Guidelines
If the machines are operated in an unusually dusty environment, it is
recommended that you periodically inspect the interior of the machines
for any collection of dust. The frequency of this check should be
determined by each individual center based upon their operating
environment.
If dust is present, the easiest methods of removing the dust are the use of a
portable vacuum cleaner or compressed air.
For areas inside the machine that a portable vacuum cleaner cannot reach,
use a small, clean paintbrush or equivalent to gently “sweep” the dust
from these areas to an area where you can use the portable vacuum
cleaner.
The Haemonetics PCS2 is checked for leakage current as part of its final
inspection before release. It will be checked on a yearly basis as part of
the Preventive Maintenance (PM) program.
More frequent current leakage checks should be performed whenever a
major spill occurs on the PCS2. To determine the necessity of a leakage
current check after a major spill, the qualified trained staff should do the
following:
1. Disconnect the donor and remove the machine from service.
2. Thoroughly clean the spill from the machine.
3. Remove the front and back panels of the PCS2 case.
4. Visually inspect for fluid leakage inside the machine.
5. If the inside of the machine is free of fluid, no current leakage check
is necessary and the front and back panels can be replaced.
The PCS2 can then be returned to service.
6. If fluid is found on the inside of the machine, it should be cleaned and
a current leakage check should be performed by a qualified center
personnel or Haemonetics Field Service Engineer before the machine
can be returned to the donor floor.
7. The earth ground leakage must not exceed 100 microamperes at 120
VAC or 500 microamperes at 240 VAC to pass inspection.
