Installation
Installing legs – required
1.Remove legs from plastic bag packed inside refrigerator.
2.Tip refrigerator back and screw legs in all the way to stop (they will extend 1/8" below base of REF).
3.Adjust legs as needed to level REF in both directions. To access legs, remove the lower front panel. Turn legs clockwise to extend legs.
Installing shelves – required
1.Remove shelves and shelf brackets packed inside refrigerator. (If ordered, find cut-out upper shelf accessory in separate box.)
2.Install shelf brackets in pilasters (insert top tab, squeeze and push in lower tab).
3.If ordered, position cut-out upper shelf accessory below evaporator with cut-out around drain.
Installing controller faceplate – required
1.Remove °F and °C faceplates from plastic bag packed inside refrigerator.
2.Snap appropriate faceplate in place over controller face.
3.If °C display is desired, resetting of temperature controller is required. See below.

Follett’s temperature controller is pre-programmed with a 34°F set point and °F display. The 34° set point delivers a temperature range of 34°F
– 38°F that may not meet the needs of your specific application. Follett’s controller set point can be changed to deliver the required range in either °F or °C. Refer to page 6 for instructions on changing set point and/or display to °C.

Reversing the door swing – optional
1.Remove screws and latch from refrigerator cabinet. (Fig. 5.1).
2.Use flat screwdriver to carefully remove (do not scratch) hinge covers (Fig. 6.1).
3.Support door and remove screws attaching hinge to refrigerator cabinet (Fig. 6.2).
4.Cover hinge screw holes with screw hole plugs removed from opposite side.
5.Reverse door and reinstall hinge screws.
6.Reinstall latch on opposite side.
7.Remove screws and handle from door (Fig. 7.1).
8.Rotate handle (Fig. 7.2).

Controller operation |
Fig. 8 |
In normal operation the controller displays cabinet temperatures in °F (default) or user-selected °C. °C temperatures are displayed to 1 decimal point.
An LED located below the snowflake icon flashes when the compressor is running.
Rocker buttons to the right of the temperature display control all programming functions.

The controller is pre-programmed with a 34°F set point which provides a compressor cut-in at 38°F and cut-out at 34°F. This may not meet your specific application needs. For example, many pharmaceutical manufacturers
recommend that their refrigerated medications be stored between 36°F and 46°F. Instructions for changing the set point are found below.
Refer to the chart below for the set point for your application’s required temperature range:

All set points have a 4°F differential (HY setting on the controller). The 4°F differential means that with a 34°F set point, for example, the compressor will turn off at 34°F and turn on when it reaches 38°F.
Caution: Do NOT change the differential (HY setting) except as indicated below in instructions for changing the °C or °F display. Changes to the HY setting can cause short-cycling and failure of the compressor.
Because there is still refrigerant in the evaporator, there can be an additional 1° - 1.5°F of downward “drift” in temperature after the compressor turns off. The temperature may momentarily display as low as 32°F (32.9°F and below rounds down to 32°F) before beginning to rise again.
