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.
24/7 OPERATION
The cabinet is designed to operate for a minimum of 2 hours with the door
open in normal ambient conditions, but is capable of operating 24 hours a
day, 7 days a week with the door closed. There are a few items to note for
this extended operation:
1. If the cabinet is used for an extended period of time with the door closed,
it may be necessary to raise the set temperature to avoid freezing the
food product.
2. If the cabinet is used for an extended period of time with the door closed,
it may be necessary to manually drain the condensate drain pan. See
section regarding drain pan instructions. For reference, active evapora-
tion in the condensate drain pan only occurs while the condenser is oper-
ating. When the door is closed for extended periods of time, the conden-
ser operates infrequently.
3. Depending on environmental and operating conditions, manually draining
the condensate drain pan may be necessary. See
DRAINING CONDEN-
SATE PAN
section in the
GENERAL MAINTENANCE INSTRUCTIONS
portion of this manual for more details.
