Unit Operation
Randell has attempted to preset the cold controls to ensure that your unit runs at
an optimum temperature, but due to varying ambient conditions, including
elevation, food product as well as type of operation, you may need to alter this
temperature.
It is strongly recommended that the doors be kept closed when the unit is not in
use and between rush periods. This is especially important in the summer and in
kitchens exceeding 80° F. Do not leave the doors open for prolonged periods of
time. Close after using.
NOTE: Even though your drop-in display case was designed for heavy use,
excessive door openings should be avoided in order to maintain proper
cabinet temperature and eliminate the possibility of coil freeze-up.
Your drop-in display case was equipped with a temperature adjustment control
located within the cabinet on the front face of the evaporator coil.
To adjust the temperature in refrigerated units:
A. To lower the temperature:
1. Turn the dial knob clockwise.
2. There are numbers to indicate settings. Keep the arrow on the
knob pointed within the numbered section of the arc.
3. Turning it clockwise beyond the numbered section can result in
freeze-up.
B. To raise the temperature:
1. Turn the dial knob counterclockwise.
2. There are numbers to indicate settings. Keep the arrow on the
knob pointed within the numbered section of the arc.
3. Turning it counterclockwise beyond the numbered section will
shut the compressor off.
NOTE: It is not recommended to turn the dial above 8 or below 1 on
the temperature control. If the adjustments still do not result
in proper temperature please contact the factory at 1-800-621-
8560.
C. If your temperature control is at the maximum setting and the cabinet
temperature still remains too low or too high, you may need to adjust
the pressure control if your display case is equipped with one.
1. Turn the right adjustment screw clockwise (1/4 turn at a time) to
a lower number for a colder temperature.
2. Turn the right adjustment screw counterclockwise (1/4 turn at a
time) to a higher number for a warmer temperature.
NOTE: Numbers on pressure control are pounds of pressure, not
degrees F.
NOTE: Do not adjust the differential screw.
