(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.

Changing temperature controller settings – optional

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.

Controller operation

In normal operation the controller displays cabinet temperatures in
°F (default) or user-selected °C. °C temperatures are displayed to 1
decimal point.

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:

41°/ 5° 45° / 41° 7. 2 °/ 5° 39° - 45°/ 3.9° - 7.2°

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.
