Start-Up Procedures
Getting Started
BEFORE YOU START
The system must be shutdown prior to any filter installation or
removal. Air flow should be stopped or a bypass of the air system
must be made.
Consult with the safety officer and perform a job safety
analysis prior to installing or removing any filter(s). Make sure
all personnel are wearing the required personal protective
equipment (PPE).
START-UP PROCEDURE
1.
Clean outside the door, work area and all metal surfaces.
2.
Provide filter: Provide a new HEPA filter(s) and or prefilter for
each tier.
3.
Remove door: Loosen all doorknobs on the section where the
filter(s) are to be removed. Lift the door off the door studs and
swing open on the hinge.
*Option - lift the door off the hinge and place in a safe location.
4.
Unseal the filter: Pull the arm all the way outward to the open
position. The mechanism will pull the filters from the gel track
via extractor clips on the filters. This allows the filter to release
from the knife-edge.
For a gasket seal housing, unlock the filter by turning both bolt-
locking mechanisms counterclockwise with a ratchet. This will
release the filter from the flat edge.
*If there are multiple filters per tier, steps 2-4 should be repeated
until all filters are removed.
5.
Remove the dirty filter(s) and dispose in accordance with all
applicable state and federal laws.
6.
Slide the new filter(s) into the housing and engage the locking
mechanism to seal off the filter(s) on the knife edge(s).
7.
Close the swing bar and latch for a gel-seal filter, or screw down
the drive bolts clockwise on a gasket-seal filter.
8.
Replace the door and tighten all the door latches.
