22. Line Filter
Follow these instructions only if you have the equipment needed to perform a
dielectric strength test (hi-pot) and a protective bonding impedance test (ground
continuity). If you do not have the required equipment, return the unit to SciCan
for servicing.
It is difficult to determine when a line filter has failed. If the unit blows mains fuses
in the service panel, there may be a short in the line filter. Disconnect all leads
from the mains input and output and test for shorted circuits.
To remove the line filter, perform the following steps:
1. Power
OFF
the unit and remove the cover. See Cover.
2. Disconnect the fan connectors.
3. Disconnect the inlet and outlet tubes on the biological air filter.
4. Remove the rear chassis cover plate by removing the 3 screws across the
top and 3 screws across the bottom, and lifting the cover plate.
5. Disconnect the white wire from
receptacle line filter position N,
the black wire from line filter
position P, and the green wire
from line filter ground position.
