Sample Transport Time
The shorter the sample line, the shorter the transport time. If monitoring a critical location, it may be desirable
to place the monitor near that critical area to reduce sample transport time for that location.
Monitor Dimensions
Monitor dimensions are important factor in monitor placement. The the basic tabletop, the dimensions are
approximately 9.187 inches (23.3 cm) high. See Rack Mount part for required clearances and mounting
dimension for the optional rack mount configurations. Monitor dimensions are important factors in instrument
placement. For the basic tabletop configuration. The Vertex™ VC4 is 17 inches (43 cm) wide and 17.9 inches
(45 cm) in depth. Allow clearance above the monitor for installing sample lines.
The Vertex™ VC4 weighs about 51 pounds (23 kg).
Sample Locations
Before installing the Vertex™ VC4 System, evaluate the sampling locations to determine the presence of
excessive dust or moisture. An external filter must be used in all locations. Make sure you use the correct filter.
Dust may be a result of construction as well as manufacturing activities. Moisture may result 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. You may need to
consult your company's industrial hygienist or safety officer before installing sample lines to determine your
company's policy related to sampling locations and monitoring of the desired sample gas.
Sample Line Particulate Filter Use
See Filter Compatibility Specifications, to determine which filter type should be used at the location.
