Appendices
One last thing...
APPENDIX A
It is recommended that the buyer supply complete information
about the operating conditions of the ventilation system prior to
installation of any HEPA side-access filter housing.
Location-specific conditions may prevent the system from
operating satisfactorily in certain applications.
Any non-factory alterations to the product may result in a
compromised installation.
Please contact the manufacturer for any questions not addressed
in this manual.
APPENDIX B – LOCKING TRAY CHANGE OUT
It is advised that any locking-tray mechanism replacement or
change out be done in a decontaminated environment. One of the
advantages of the Tri-Lock FS/GS housings is the ability to change
out locking trays in the field.
Change out is a simple task. The same concept that applies to
filters applies to locking mechanisms—refer back to the Start-Up
Procedures.
First, remove all filters from the contamination unit following the
aforementioned Start-Up Procedures.
Fluid Seal Method
1.
Using the ratchet with a ½” socket, remove the two hex nuts and
washers for both the top and bottom locking trays.
2.
Then switch to a ⅜” socket, and remove the hex nut and washers
from the linkage to the door swing arm.
3.
Remove both the top and bottom parts to each pair of locking
trays.
4.
Treat the locking mechanism as a dirty filter and continue the
appropriate steps.
Gasket Seal Method
1.
Using a ratchet with a ½” socket, remove the two hex nuts and
washers for both the top and bottom locking trays.
2.
Lift the top half of each locking tray off the studs and into the bag.
3.
Remove the pipe bearings from the locking mechanism and
back off the drive bolts to release the bottom locking trays.
4.
Remove the bottom-locking tray.
5.
Treat the locking mechanism as a dirty filter and continue the
appropriate steps.
