    5. Disconnect the bottle. Maintaining Liquid in the Reservoir A full reservoir contains enough butanol for the Model 3760A CPC to run continuously for seven days and the Model 3762 for four days. If you are running the CPC continuously, make sure the working fluid in the reservoir is replenished every seven days for the Model 3760A and every four days for the Model 3762.

  • Page 45: Draining The Reservoir

    Draining the Reservoir Butanol has a tendency to absorb water over time when it is exposed to humid conditions, so you should drain the CPC reservoir on a weekly or as-needed basis. You should also drain the reservoir if you are moving the CPC from one location to another.
