TEMPERATURE CONTROL
PRODUCT TEMPERATURE CHECK: (Reference only)
Allow vendor to run 24 hours. Vend product, insert test device (thermometer) into beverage.
TEMPERATURE CONTROL SETTING:
The temperature inside the cabinet is regulated by the Temperature Control, located on the left
side of the Evaporator (see Figure 10 ). Before adjusting control, make sure the refrigeration
system is working properly. Check that all fans run freely and do not make excessive noise.
Check that the vanes of the Evaporator are free of obstructions. Air flow over the vanes is
important for proper operation of the refrigeration unit. Check the door for a tight seal.
When the air temperature at the Capillary tube reaches 39 degrees Fahrenheit, the refrigeration
system will cycle on (see Figure 11). To decrease the temperature, turn the Temperature
Control Screw clockwise (see Figure 10). To increase the temperature, turn the screw counter-
clockwise. The temperature will change approximately 6 degrees with every 1/4 turn of the
control screw.
The Capillary tube is positioned in the air flow of the evaporator (see Figure 11). It must not
touch the rear of the cabinet wall or the evaporator shield (except at the clip). It is possible to
distort the position of the tube upon replacement and installation. If the refrigeration system is
replaced, check the Capillary tube’s position.
