UNDERSTANDING THE REFRIGERATION CYCLE:
The Refrigeration Controller unit that manages all the refrigerator operations and performance is a rugged and highly
sophisticated commercial grade Sporlan Electronic Controller.
Like all refrigerators, as the unit cools and maintains the desired product temperature, it’s internal temperature will fluctu-
ate between ON and OFF periods depending upon ambient temperature, how many times the door is open and for how
long it’s held open.
To minimize ON (running) times and save energy, it is recommended to open the door for the smallest amount of time
and frequency.
The ARFG-42 unit is factory preset with a set point of 35°F and with a 3°F differential cycle.
This means that the ARFG-42 unit will refrigerate until it reaches 35°F internal air temperature. At that point, the unit will
turn OFF and will remain off until it reaches 38°F
(Due to the 3°F differential temperature cycle).
It is important to understand that your product will not actually reach 38°F.
The “average” product temperature will settle somewhere midway between the ON and OFF set points (approximately ~
37°F) depending on the product type.
Please refer to the following graph for a representation of the refrigeration cycle:
The 3°F differential is used to provide you with the best possible energy savings. A smaller differential would cause the
unit to start and stop several times per hour wasting energy.
The Electronic Temperature Controller in the ARFG-42 allows the user to change and adjust the default set point (35°F)
between 25°F and 45°F, consequently the product temperature will average lower or higher temperatures as desired.
Please refer to “CONTROLLER SETTINGS”
Always remember:
When the door is opened on the ARFG-42, the display will read the cabinet temperature at that very moment. That is not
your product temperature.
