Temperature verification with the bottle locating base
Should there be a need to verify the temperature readings dis-
played by the control panel, it is important to read the temper-
ature as close as possible to the sensor inside the refrigerator.
To verify the temperature without a 24-bottle rack or locating
base, place the refrigerator thermometer in the back-right corner
of the refrigerator. The thermometer should sit in front of the
return air opening to the refrigeration system, but not obstruct
the air flow.
To verify the temperature with the 24-bottle rack, place the
refrigerator thermometer on the rack near bottles 20 and 21
(Figure 5-4). For samplers with the bottle locating base, place the
refrigerator thermometer between bottles three and four
(Figure 5-5).
The refrigerator thermometer can be read after 30 minutes and
compared with the displayed refrigerator temperature (section
5.2.8).
