EC155 Replacement Chemical Bottles: The EC155 has two small bottles

filled with chemicals to remove CO

and water vapor from the inside of the

sensor head. If replacement bottles are needed, two bottles are included with

pn 26511.

Diaphragm Pump: The pump module for the CPEC200 includes a small

double-head diaphragm pump with a brushless DC motor. The pump includes

a speed-control input and a tachometer to measure actual pumping speed. It is

mounted in an insulated, temperature-controlled box inside the CPEC200

system enclosure. If the pump fails, the replacement pump (FIGURE 4-15) is

available as pn 26402. The part includes the connector for easy installation.

See Appendix H, CPEC200 Pump Replacement, for instructions on replacing

the pump.
