The Parker Zero Air Generator is designed to operate continuously, 24 hours per day as long as the 
compressed air or power supply is not interrupted. The LED indicator lights on the front panel of the 
Parker Zero Air Generator give the operator instantaneous feedback regarding system function. The 
“Start-Up” (yellow) and “THC” (yellow and green) LEDs show system operational status; the “Overflow” 
(yellow) and 

“Check System” (red) LEDs show the need for operator attention or system maintenance. 

 

During normal operation, the display on the Parker Zero Air Generator will have the 

green “THC” LED 

illuminated.  If the 

“Overflow” LED, “Start-Up” LED, “Check System” LED, or yellow “THC” LEDs illuminate 

during routine operation, please consult the Troubleshooting Guide at the end of this bulletin. 

 

The 

“Check System” LED will blink occasionally during normal operation. The blink rate will increase as 

the system approaches 3 years of operation. At that time, the catalyst module should be replaced. 

 

If the 

“Check System” LED is solid red, please consult troubleshooting guide. 

 
The equipment shall not be placed too close to the wall so that it does not hinder the removal of the power 
cord. Do not use a power cord below the specifications of the provided power cord. 
 
To prevent excess demand on the Parker Zero Air Generator, use a flow control device downstream from 
the unit. If the flow capacity of the generator is exceeded, the 

“Overflow” LED and yellow “THC” LED will 

illuminate, indicating that hydrocarbon content exceeds 0.1ppm. 

 

Note:  To ensure hydrocarbon content of less than 0.05 ppm (Models HPZA-3500,

 

HPZA-7000, and HPZA-18000), a flow control device must be installed downstream from the 
generator to prevent downstream demand in excess of the 

generator’s maximum flow rate.

 

 

To shut down the Parker Zero Air Generator, simply turn the power switch to the off position and turn off 
the compressed air supply to the generator. 
 
 

Maintenance 

All maintenance procedures for Parker Zero Air Generators should be performed by suitable 
personnel using reasonable care.

 

Prior to servicing the Parker Zero Air Generator, turn off the compressed air and power 
supplies to the generator, and ensure that the system is depressurized.

 

To ensure consistent product performance and reliability use only genuine Parker replacement 
parts and filter cartridges. 

The primary maintenance tasks required by the Parker Zero Air Generator are changing the prefilter 
cartridges (annually), replacing the final membrane filter cartridge (annually), and replacing the catalyst 
module (when the 

“Check System” LED illuminates or blinks). A summary of the replacement part 

numbers and recommended service frequency is shown at the end of this Maintenance section. See 
Figure 6 for the locations of the various maintenance items.

 

Replacement prefilter cartridges, final filter replacement cartridges, and catalyst modules may be 
ordered through a local representative. For convenience, a one-year supply of these replacement 
cartridges has been assembled into a maintenance kit (P/N MK7840). The kit contains one first stage 
coalescing prefilter cartridge (P/N 100-12-DX), one second stage coalescing filter cartridge (P/N 100-
12-BX), and one Grade GS final membrane filter (P/N GS-050-05-95).

 

If  necessary,  the  Zero  Air  Generator  may  be  wiped  clean  with  a  dry  cloth  on  an  as  needed 
basis.  Do  not  use  water,  aerosols, or  other  cleaning  agents  to  clean  the  units.  Use  of  any 
liquid detergent to clean the generator could present an electrical hazard.
