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.
