a. When using an air sensor, the wine
bottle temperature
controlled
temperature. If the set-point is 55F
with the differential 4F, the cooling
unit turns
temperature and turns off at 55F of
air temperature. The average air
temperature is 57F, and then the
wine temperature is around 57+/-
0.5F. The air is light enough to
change so quickly that it maintains
relatively
temperature that would prevent wine
bottle temperature from varying.
a. Check for gasket and door opening
b. Lower setting
c. Check for excessive size
d. Check for installation location
e. Leave 4~6 "clearance between the
exhaust side and the wall or ceiling;
leave 2~4" clearance for the fresh-
air supply side; leave 1~2" for the
other sides
f. Check for both evaporator and
condenser fans
g. Check for air restrictions
