Placement Of The Vertex M System; Exposure To Dust And Humidity; Sample Transport Time; Monitor Dimensions - Honeywell Vertex M User Manual

3.2.1 Placement of the Vertex M system

Install the Vertex M system in an environmentally- protected setting remote from the
manufacturing or storage locations that it monitors.
Note: Refer to "Installation Drawings" on page 157 on lifting/mounting.
The Vertex M system can be placed at maximum 400 ft. See "Sample Transport Time" below for
more information.

3.2.2 Exposure to Dust and Humidity

Exposure to corrosive gases or materials, excess moisture, dust and other unusual
environmental conditions could seriously hamper the Vertex M's monitoring ability and could
damage the monitor. Allow room around the Vertex M system for ventilation and servicing.

3.2.3 Sample Transport Time

Install the Vertex M system central to all 24 sample locations to achieve equal sample transport
times during monitoring. If monitoring a critical location, it may be desirable to place the
monitor near that critical area to achieve minimum sample transport times for that location.
See "Specifications" on page 165 for more information on transport times.

3.2.4 Monitor Dimensions

Monitor dimensions are important factors in monitor placement. The Vertex M system is 24. in.
(61 cm) wide, 36 in. (91.4 cm) deep and 57 in. (144.8 cm) in height. The system with 3 analyzers
weighs about 550 pounds (249 kg). Allow for 24 in. (61 cm) door swing; 5 in. (12.3 cm) at rear
and 5 in. (12.3 cm) on sides. Allow clearance above monitor for installing sample lines.

3.2.5 Sample Locations

Before installing the Vertex M system, evaluate the sampling locations to determine if excessive
dust or moisture are present. An external filter must be used in all locations. Make sure the
correct filter is used. Dust may be a result of construction as well as manufacturing activities.
Moisture may occur from rain entering a line at an outdoor sampling location or from
condensation caused by temperature fluctuations. Water condensation in the sample lines
could cause false alarms.
Note: Variables such as airflow, the molecular weight and temperature of the sample gas, and
the physical conditions of the areas being monitored influence the placement of the sampling
locations. Consult of the company's industrial hygienist or safety officer may be needed before
installing sample lines to determine the company's policy related to sampling locations and
monitoring of the desired sample gas.
