Equalizer Field Reset (Original Style)
NOTE: Environment One does not recommend opening the original style
equalizer as it is delivered from the factory.
In the event that the equalizer diaphragm is thought to be collapsed, you should
disconnect the equalizer tube from the equalizer itself. If the problem goes away then
you should inspect the equalizer diaphragm. If the problem persist then the equalizer
diaphragm is more than likely not collapsed. If the equalizer diaphragm is collapsed,
then the following procedure can be used in the field to reset the diaphragm.
1. Using your fingers, carefully pry the equalizer apart at the snaps. Do not use a
screwdriver or any other tool to pry the snaps. If you are unable to pry it apart
with your fingers, then a factory new equalizer needs to be installed.

2. Remove the collapsed diaphragm, clean and dry it, and reshape it to the neutral position.
