Carter-Hoffmann PHB15 - Manual (Page 4)

The Air Screen Refrigerator is designed for use with the door open when un-
loading during meal or tray assembly operations lasting up to two hours. Only
product that has been pre-chilled should be placed in the cabinet. Placing
warm product into the cabinet will elevate the cabinet air temperature above
40
°F (4°C). This will have a direct effect on optimum product serving temper-
atures.
Due to various conditions such as extremely high kitchen temperatures, high
frequency of tray activity breaking the air curtain and excessively long opera-
tions, the door may need to be closed so the unit can recover to proper oper-
ating 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).
2. Load the cabinet from the bottom to the top. While the side-to-side air
flow of the Air Screen Refrigerator will function well when trays are partially
pulled out, the best position for the trays is to be pushed all the way in dur-
ing unloading. After loading, close the door and allow the inside air temper-
ature 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 or freezer 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.
