11.4. THREE-YEAR CATALYST CHAMBER REPLACEMENT
The catalyst chamber used in the GC Zero Air generator should be replaced every three years to maintain
carbon monoxide and hydrocarbon specications. The system should be shut down as described above prior
to replacement. Allow the unit to cool down for a minimum of two hours before replacement.
• If the generator has just been powered off and the catalyst is still hot, DO NOT turn off the air until the
catalyst has been cooled down.
• Remove the outlet connection and allow the outlet air to ow freely for two hours to cool the catalyst.
After two hours of cool-down, disconnect the air supply. Depressurize the system by depressing the pin at
the bottom of the inlet lter housing.
• Open top cover
• Carefully disconnect the two compression air ttings to remove the cooling spiral.
• Remove heater connections from the control board.
• Unscrew the two screws to remove the aluminum plate from the metal heat shield covering the catalyst.
• When the catalyst chamber is cool enough to touch, extract the catalyst chamber from the side.
