Ammonia Gas Monitor – Multi Zone
12 Instruction 3015-5113
Connecting Air Lines
Overview
Individual sample lines are run from the AGM-MZ to each area of the facility to be monitored. Additionally, a
purge line is installed to provide clean air for resetting the infrared zero baseline. All air line connections,
located on the left side of the enclosure, are displayed below.

Tubing Considerations
Use ¼" outside diameter (0.040" wall) flex tubing for all air lines (P/N 3015-5111) or equivalent. The tubing
should be clean and free of residual moisture or other contaminants. The tubing should be cut cleanly with a
sharp knife and care should be taken not to distort the tubing end.
To connect the air lines to the monitor simply push the tubing firmly onto the connector. To remove a line,
depress the plastic ring on the connector with one hand while withdrawing the tube with your other hand. All
tubing bends should have a radius of no less than 5" to ensure proper airflow. If kinks or obstructions occur in
any of the air lines the instrument may not function properly.
Connecting Purge Line
A purge line is required to draw fresh air into the instrument and should not exceed 300 feet in length. It is
advisable to terminate the purge line outdoors, provided the input is not exposed to rain, snow, ice, exhaust
fumes, or other airborne contaminates. If an outdoor installation is impractical, the line should be run to an
area inside the facility that you are certain is not contaminated with ambient ammonia gas.
Connecting Exhaust Line
An exhaust line can be used when it is required to vent gas samples away from the instrument and should
not exceed 300 feet in length. The exhaust line should terminate in a location that is completely isolated
from the purge line termination point and other areas of the facility that will be monitored. Ideally this line
should terminate outdoors in a location that is not exposed to the elements. This line does not require a
line-end filter. If the exhaust line terminates outside the building, position the tubing so that no water or
moisture can enter it.
Connecting Sample Intake Lines
The AGM-MZ is designed to accommodate up to 16 separate sample intake lines. The standard
configuration of the unit includes one manifold of 4 intake connectors and 1 purge connector. Additional
manifolds can be easily installed to increase monitoring capacity (field installation kit P/N 3015-5171, and 4
zone line end filter kit P/N 3015-3411).
Sample intake lines can be up to 500 feet when no exhaust tubing is used. Otherwise, the combined length
of the sample line and the exhaust line cannot exceed 500 ft. All line terminations should be positioned to
reduce the possibility of mists, aerosols, oil, water, dust, or other contaminates being drawn into the
instrument. A line-end filter (P/N 3015-3420) should be attached to the end of each sample intake line.
