Page 4: Introduction
ACS3920. You will only be able to generate down to around a -70 °C frost point when using the ACS3920. It is also important to adjust the internal Model 3920 or Model 3900 regulator to 80 to 90 psiG to assure proper pressure control. -
Page 5: Safety Guidelines
If possible, save shipping container for future use. Location Locate the ACS3920 on the floor with the outlet within five feet of the generator’s gas inlet and at least 12 inches away from the wall or other obstructions that would restrict the flow of air to or from the ventilation openings. -
