METHOD 1:
CAUTION
Do not close off all discharge vents. Doing so can
damage the refrigeration unit.
The air discharge and return vents are located in the right front and rear side wall. The vents are ad-
justed by loosening the screw and sliding the air duct shutter up or down as required. With the shutter
all the way up, the vent is fully open. The vent is closed when the shutter is all the way down. Ideally,
the temperature at the top tray should be the same as that
at the bottom tray. Using a thermometer to monitor tem-
perature, adjust the air discharge and return vents until the
temperatures are as close together as possible.
