Re-connect the replacement catalyst module by reversing the removal procedure. Hand tighten
nuts on to ferrules and finish tightening with a wrench 1-1/2 turns for a tight seal. Prior to turning
the zero air generator on, check for leaks by opening the compressed air supply to the unit. Use
a soap or leak detecting solution to check the integrity of the piping and fittings.

Replace cover, without capturing any electrical wiring, and commence operation as detailed in
the Start-Up section of this manual. The
“Check System” indicator light on the front of the
generator will flash for 2 to 3 minutes after start-up, until the circuit board and the catalyst
module have been initialized. After the initialization period, the generator will commence
operation from the warm-up stage. (
Note:
if the
“Check System” indicator light continues to blink
after 5 to 10 minutes, please contact the factory.)
Occasionally, one or both of the fuses in the Zero Air Generator may burn out. The fuses are located
in the power receptacle on the left-hand side of the generator.
Before servicing the fuses, turn the generator off and disconnect the power cord from both
the power supply and the generator power receptacle.
To access the fuses, use a small screwdriver to remove the fuse holder located in the power
receptacle of the generator. In the Zero Air Generator, both the phase and neutral are fused
separately. As a result of this configuration, both fuses should be checked any time fuse
replacement is warranted. Replace either one or both fuses as necessary and re-assemble.
To
maintain the safety and performance integrity of the product, use only fuses of the size and
type detailed in the specifications section of this bulletin.
