Convenience Outlet
(Chromatography Refrigerators Only)
The Chromatography Refrigerators come equipped with a
convenience outlet located in the center of the back wall.
Models 140,141 (three doors) have two convenience out-
lets. The power to the outlets is protected by a circuit
breaker. The breaker is located just below and to the
right of the outlet. Pressing the breaker button resets the
breaker after a fault.
