The Parker PCO2 range of plant scale Carbon Dioxide Quality Incident Protection Systems comprise of the now obsolete Maxi PCO2 / Mplus PCO2 models and the current PCO2 MKII models. The systems have been designed to incorporate six stages of purification, offering effective quality incident protection against a combination of potential contaminants.

Regular planned maintenance schedules of the PCO2 System's adsorbent cartridges and pre and post filter elements are a major part in ensuring total protection from a quality incident. Complete maintenance should be undertaken every 12 months for PCO2 MKII models and every 6 months for Maxi PCO2 / Mplus PCO2 models, each model has a designated maintenance kit part number. Details of the kit part numbers can be found within the user guides supplied with each system.

For Maxi PCO2 and Mplus PCO2 models the serial number of the unit will determine which maintenance kit is required, if unsure which please refer to this instruction:

• PCO2 Systems with Oil-Xplus filters - Maxi models (up to serial number PC0766) and Mplus (up to serial number MPC0151)

• PCO2 Systems with Oil-X EVOLUTION filters - Maxi models (from serial number PC0766 to date) and Mplus (from serial number MPC0151 to date)

It is advised that the filter elements are changed during the same planned maintenance schedule that the adsorbent cartridges are replaced. Replacing the elements during the same period will reduce downtime and the amount of time that the PCO2 system is exposed to atmosphere and potential contamination.
