Condenser Fan
The interior lamp is controlled by a rocker switch on the header panel.
This light may be operated any time the cabinet power is turned on at
the keyed power switch. If the interior lamp fails, replace with the
same size and wattage lamp. DO NOT USE REDUCED WATTAGE
LAMPS. The reduced wattage lamps generally fail to light below 60
°F (15 °C).
Chromatography Refrigerators come equipped with a convenience
outlet located in the center of the back wall. Model 172G’s (three
doors) have two convenience outlets. 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.
WARNING: The convenience outlet is LIVE at any time the
unit is connected to an electrical power source, regardless
of the position of the key switch.
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 continuously in the manual setting to
better dispose of this water. At times of low relative humidity, the
switch can be set to automatic.
