SHARP EDGES
RISK OF SERIOUS INJURY
Sharp edges are present inside the Wine Guardian system.
Pre-installation Test
Test the system before installing it to check for non-visible shipping damage.
To test the system:
 Set the system on the floor or a sturdy level surface. 
 Plug in the system. 
 Press the on/off switch, control illuminates. This indicates the system has power. 
 The built in timer prevents short cycling and keeps the system from turning
on right away. The system comes on and runs as long as the temperature of the
space is above the thermostat set point. After several minutes, cold air comes out
of the system from the evaporator section side and hot air comes from the
condenser section. Listen for any unusual noise or vibration.
