Convenience Outlet
(Chromatography Refrigerators Only)
Chromatography Refrigerators come equipped with a con-
venience outlet located in the center of the back wall.
Model 172G’s (three doors) have two convenience out-
lets. The total power that can be supplied by the outlet
(or outlets in 3-door models) is 5A @ 120VAC (4A @
120VAC for the 3-door models). The outlet(s) is protected
by a circuit breaker located just below and to the right of
the outlet(s). Pressing the breaker button resets the
breaker after a fault.
Manual/Automatic Condenser
Fan
A rocker switch located on the left side of the top of the
inside of the chamber is used to operate the condenser
fan automatically or manually. With the switch in the
automatic position, the condenser fan operates with the
compressor. In the manual position, the condenser fan
operates continuously.
During times of high ambient relative humidity conditions,
more water is condensed on the evaporator and directed
to the condensate pan. The condenser fan will run con-
tinuously in the manual setting to better dispose of this
water. At times of low relative humidity, the switch can be
set to automatic.

Warning
The convenience outlet is LIVE at any
time the unit is connected to an elec-
trical power source, regardless of the
position of the key switch.
