PHB refrigerators are capable of cooling to a temperature of 32

°

F (O

°

C). Pre-

cooling time to 40

°

F (4

°

C) is approximately 40 minutes. Only product that has 

been pre-chilled should be placed into the cabinet. Placing warm product will 
elevate the cabinet air temperature above 40

°

F (4

°

C) . This will have a direct 

effect on optimum serving temperatures. 

 

Due to various conditions such as extremely high kitchen temperatures and/
or humidity, high frequency of tray activity and excessively long operations, 
the door may need to be closed so the unit can recover to proper operating 
temperature. 

 

1.  Pre-chill empty cabinet with the door closed for approximately 40 

minutes. Always keep the door closed, except when actually loading or 
unloading the cabinet. Do not load the cabinet until the proper operating 
temperature has been reached (34

°

-40

°

F for refrigerators. Power switch 

will illuminate when cabinet is “ON”. 

2. 

Load the cabinet from the bottom to the top. 

After loading, close the 

door and allow the inside air temperature to recover. 

3.  If necessary, unplug and move cabinet to serving area. Plug cabinet 

back in immediately upon arrival. 

4.  Unload the cabinet from the top down. 

5.  Close the door during slow periods to extend the effective temperature 

maintenance time. 

 

Remember: the refrigerator must be at proper  

 

temperature before the door is opened.

 

 

 

The cabinet will not lower food temperatures with the door open. 

 

The cabinet is equipped with an automatic condensate evaporator. To pre-
vent water spills, leave the unit plugged in, with the door closed for at least 90 
minutes after use.
