6.3 Maintenance procedures
6.3.1 General Sampler Component check
• Check power cords for cracks, fraying, wear or brittleness, cuts or other
damage.
• Check tie-downs or attachment to fixed structure for security
• Inspect the filter holder and rubber gaskets*
• Ensure there is no damage to the inside or outside of the housing.
* When an exposed filter is removed from the cassette the particulate matter boundary should be
clearly defined on the filter. If the boundary is diffuse or shows irregularities then the rubber gaskets
may be leaking and require replacement.
6.3.2 Automatic Flow
Check operation of automatic flow compensation device by placing two filters in the
filter cassette
6.3.3 Cassette
Clean the sampler and wipe the cassette and supporting structure with a damp cloth
Note: Do not use solvents to clean plastic or
rubber components, including labels, seals,
electrical components, etc.
6.3.4 Size Selective Inlet
The greased collection shim inside the size selective inlet must be periodically
cleaned and regreased. To re-grease the collection shim, release the four catches that
secure the plate and remove it from the size selective inlet. Wipe off the old grease
before spraying with a thick coating of the correct grease.
Re-greasing of the greased collection shim located inside the size selective inlet
should only be done using Dow Silicone Slipicone Release Spray (#316). Any other
type of grease may effect the particle collection characteristics of the inlet and
therefore should not be used.
When re-assembling the size selective inlet ensure that the hooks are aligned with the
slots in the top section of the inlet.
It may be necessary to adjust the catch length periodically as the rubber seals
compress.
