GENERAL INFORMATION ON DUSTUBES
INSTALLATION AND REMOVAL:
When an inside shaker device is used, the tubes next to the shaker device should be turned at a 45 angle to secure
proper operative clearance. Care should be used to keep the vertical seams of the tubes straight and not twisted.
A tube improperly installed makes the entire installation ineffective; defeats the purpose of the collector. It is not enough to
"stuff" the tube into a cell hole in a haphazard manner, or try to pull the expanded spring upward into a cell hole. (This
is permissible only to straighten a tube after being installed).
