REPAIR AND MAINTENANCE
Routine maintenance consists of checking the Hydrophobic Filter for clogging or contamination,
checking the needles for clogs, and cleaning the flow path between the needle and the filter. For
clean samples, such as most plastic resin pellets, this is seldom necessary. For very dusty, high
moisture or high volatile content samples, it may be necessary more often.
CAUTION:
Line voltage is present under the instrument’s cover. To prevent electrical shock, turn off
power, and remove the power cord. Do not re-connect the power cord and turn power on
until after the cover is secured in place.
