Manual Part No. – 80002-046

1.0 Introduction

The ProAir 2200 is a compressed air monitoring instrument that measures and detects certain hazards in compressed air supply

systems. The instrument is available with up to 4 internal sensors. Available sensors include, but are not, limited to carbon monoxide

(CO), carbon dioxide (CO2), Hydrocarbons (HC), for variations in the oxygen (O2) content and for dew point. The sensors can be

used alone or up to four sensors can be used together. In the instrument, a sample of the compressed air is passed over each sensor

and the resulting electrical outputs are used to evaluate the air for the target gases.

The ProAir 2200 is a highly adaptable instrument. Some adaptations require an addendum be added to the manual to facilitate use of

the instruments with these adaptations. If addendum is needed, see page(s) between sections replacement part numbers and warranty.

Some features of the instruments are as follows:

continuous monitoring of the sample air

continuous LCD display of gas and vapor concentrations

menu driven operational and maintenance controls

menu driven calibration procedure

audio and visual alarms indicate unsafe conditions

alarm relay contacts available on terminals

a fault relay and visual fault alarm

low air flow fault indication and display

alarm acknowledgement capability including audio defeat

mA outputs for each target gas

Hydrocarbons (HC) are limited to gases with an ionization potential of 10.6 eV or less. See Appendix B for a list of gases and IPs.

NOTE:All specifications stated in this manual may change without notice.

3.0 Installation

3.1 Mounting of Instrument

The ProAir 2200 should be located near the pipe or tank containing the air to be monitored, and upstream from where the air is

being used. The ProAir 2200 must be installed such that it samples the compressed air before it reaches the users.

Mount the instrument on an appropriate vertical surface using the mounting flanges provided. Avoid areas with excessive

vibration or temperature extremes. The holes in the flanges are 0.31 inch in diameter and form a 6 x 10.75-inch rectangle. See

Figure 3.

It is recommended to use #8 drywall anchors and screws for mounting the ProAir 2200 to a drywall/sheetrock surface.

Dimensions are in inches. Figure 3: ProAir 2200 Mounting Dimensions

Manual Part No. – 80002-046

3.2 Sample Air Supply

Tap the pipe or tank containing the breathing air and use appropriate fittings to connect the sample input hose. The instrument is

designed to operate from an air supply pressure 55 PSIG.

The sample air exits through the luer fitting(s) located on the bottom of the enclosure. See Figure 1. Take care not to obstruct this

exit port.

3.3 Power Supply

The input power can vary from 100 to 240VAC, 50/60 Hz. Mains power should be connected to the Power Input Terminal J23 and

the ground screw J21. See Figure 2 for location.

WARNING:Continuous gas detection and alarm systems become inoperative upon loss of primary power.

Upon supplying air and power to the instrument:

The green power on LED is lit.

The display backlight is lit, and instrument will step through a start-up sequence: unit serial number, software revision and

gases monitored may be shown on the display.

The instrument may go into alarm briefly, but the sensors stabilize quickly. If the instrument persists in alarm, acknowledge the

alarm by pressing the AUDIO DEFEAT / ALARM ACKNOWLEDGE switch. If alarm persists longer than 30 minutes, call ENMET

customer service personnel.

3.4 Outputs

Two types of alarm outputs are available, relay contacts and 4-20mA outputs.
