SECTION 2 SAFETY
INSTRUCTIONS
2.1
INSTALLATION SAFETY
Before starting or installing the CO2-PG80 Purge Gas
Generator, be sure that all power to the unit is off, valves are
shut, and the air circuit is at atmospheric pressure. DO NOT
remove, repair, or replace any component, control filter, or part,
while the unit is energized or the air circuit is under pressure.
Unplug unit and de-pressurize the unit before starting
installation or maintenance procedures.
The CO2-PG80 is rated NEMA 1.
2.2
OPERATION SAFETY
DO NOT OPERATE THE CO2-PG80 PURGE GAS
GENERATOR AT COMPRESSED AIR PRESSURES ABOVE
150 PSIG
. UNIT FAILURE, INJURY AND EQUIPMENT
DAMAGE COULD RESULT
CAUTION:
EXCEPT as otherwise specified by the manufacturer, this
product is specifically designed for compressed air service and
use with any other gas or liquid is a misapplication.
Manufacturer’s warranties are void in the event of a
misapplication
and
manufacturer
assumes
NO
RESPONSIBILITY for any resulting loss.
Before using equipment with fluids or gases other than air,
consult Altec AIR for written approval.

Note: Outlet flows shown above are maximum capacities and should not be exceeded for best performance. No outlet flow
metering valve or flow meter is installed on the adsorber/dryer and must be provided by the user. Purge flow is metered by
integral fixed purge orifices. Capacities are based on inlet conditions of 70°F, 100%RH, normal ambient CO
2
levels of approx
350-375 ppm. Outlet concentration of CO
2
will be less than 1 ppm and outlet dew point better than -100°F. If your flow,
temperature or pressure are different from above, consult factory for performance.
Unless otherwise specified, a #32 orifice
set has been installed as standard.
