Installing Sample Line Particulate Filters - Honeywell CM4 Technical Handbook

CM4 Four-Point Continuous Monitor

3.7 Installing Sample Line Particulate Filters

See Appendix A to determine if you can use sample line filters with
your target gas.
Attach a sample line filter to the sampling end of the line only if you
have determined that environmental dust or moisture is a concern at
the sampling location.
CAUTION
When attempting to use a sample line particulate filter, keep in
mind that excess amounts of dirt in the filters reduce the sample
flow and may affect concentration readings of the analyzer.
See Appendix A to determine which filter to use with your target
gas.
3.8 Installing Pump Exhaust Line
This section describes exhaust connections and installation.
3.8.1 Exhaust Line Installation Guidelines
Properly ventilate the exhaust line, which should not exceed 50 feet
(15 m) in length. If longer distances are required, contact Honeywell
Analytics.
• If multiple CM4s are installed in the same location, use a
separate line for each exhaust outlet
• Do not crimp exhaust lines, or place them in an area where
weight could collapse the tubing, or bend them to less than a
5-inch (12 cm) radius
• Leave as many bends as possible exposed for periodic visual
inspection of the line for kinked or damaged tubing
• Varying exhaust pressure can induce pump failure
CM4 Technical Manual
3.8.2 Exhaust Tubing Specifications
The instrument includes 50 feet (15 m) of 3/16 inch (4.7 mm) I.D. x
1/4 inch (6.35 mm) O.D. polypropylene tubing.
3.9 Connecting AC Power Cord
The CM4 requires a dedicated AC power line. Configurations
include:
• 120 volt ± 10%; 60 Hertz; 3 amp
• 100 volt ± 10%; 50 or 60 Hertz; 3 amp
• 220/240 volts ± 10%; 50 or 60 Hertz; 2 amp
The CM4-P requires:
• 100-120 volt ± 10%; 60 Hertz; 5 amp
• 220/240 volts ± 10%; 50 or 60 Hertz; 4 amp
Plug the line into a dedicated outlet having sufficient amperage
capacity.
Line voltage should fluctuate no more than ± 10%.
