Page 4: Introduction
INTRODUCTION - This manual describes the installation, operating, and maintenance instructions for the Pneumatech PMNG Cabinet Series membrane nitrogen generator. Please read and be familiar with this manual before attempting to operate the unit. Although this unit is very simple to operate, the user will be working with high-pressure gas that must be handled with caution. -
Page 5: 2.0 Safety
2.0 SAFETY GENERAL - This unit has electrical equipment and standard process plant components, which can be hazardous to individuals unfamiliar with such equipment. It is the users’ responsibility to permit only trained and qualified process plant operators familiar with the handling of compressed gases to operate this equipment BREATHING - This unit is designed to produce high purity nitrogen from 95-99.995% purity. -

INSTALLATION INSTRUCTIONS GENERAL - The Pneumatech PMNG Cabinet Series membrane nitrogen generator is designed for ease of installation. Since it is a packaged system, there are few connections to be made before the unit can be placed into operation. A single point air inlet, electrical connection, condensate drain, and a final nitrogen gas, nitrogen tank connection are required for a proper installation. -
Page 7: Nitrogen Piping Connection
NITROGEN PIPING CONNECTION - The final nitrogen connection is made into a ½” NPT (F) bulkhead connection on the utility end (back) of cabinet. No other check valves are required or recommended beyond this point. An isolation ball valve is provided for field installation by others. PERMEATE GAS CONNECTION - A 1”... -
Page 8: Description Of System
DESCRIPTION OF SYSTEM - The PMNG Cabinet Series membrane nitrogen generator is a modular system consisting of pre-filtration, separation, and distribution sections. Controls for the system are included in the nitrogen separation unit. Ambient air enters the feed air compressor, which is typically an oil injected rotary screw air compressor via its inlet filter. - Page 9 The nitrogen membrane module(s) are located in the heated air stream. On low purity multiple module systems 99.5% and below, the membranes connected parallel. On high purity multiple module systems 99.5% or higher, they are connected in series or combination of series and parallel. High purity systems have separate permeate connections.

Critical Adjustments – There are certain settings and adjustments that should not be tampered with. If these are re-adjusted without written consent of Pneumatech, Inc., all or part of the warranty on the unit may become void. These are the as follows: Heater controller is factory adjusted for from 70-105 degrees F and should not be re-adjusted above 110 degrees or membrane performance can decline over time. - Page 12 affect warranty. Instructions are given for adjustment in section 9, if for any reason the controller must be replaced or re-adjusted. On/Off Selector Switch – If the unit is supplied with heater and controls, (but no Operator Interface), the panel will have an On/Off selector switch to start & stop the system. The unit will requires pressure on the system before the heater will run.
- Page 13 ∆ ∆ ∆ ∆ Ρ Ρ Ρ Ρ Gauge & Message – If unit is supplied with this option, the filter elements can be changed whenever the differential pressure exceeds the setting on the switch. This switch is factory adjusted to approximately 10 PSID and should not require adjustment.

Setpoint Temperature A small “blinking” S1 will appear in the upper left of the display. Press the "#keys to advance to the desired setpoint of 120 degrees F.
- Page 15 ROUTINE MAINTENANCE SCHEDULE Daily Check for air and nitrogen leaks. Tighten or re-tape fittings as necessary. Check that the Membrane Inlet pressure is as established upon setup of the equipment Check that the inlet air temperature is less than 105°F and pre-cool if necessary. Check that hour meter (if equipped) is operative.
