purchased as a single bottle unit only, the wires for multiple bottle operation are not run. If multiple bottle
operation is desired, a conversion o f t he unit t o multiple bottle o peration will need to be done at t he factory.
To connect them follow the instructions listed below:
A) Locate the cable comming out of the bulk head fitting on the left front of the electronics
enclosure. It runs down through the top of the refrigerator. For single bottle units, there are two
female contacts on the end. For multi-bottle units, there is a black connector.
