Cabinet
Operations
The Air Screen Refrigerator is designed for use with the door open when unloading
during meal or tray assembly operations lasting up to 45 minutes. Only product that has
been pre -chilled should be placed into the cabinet. Placing warm product into the cabinet
will elevate the cabinet air temperature above 40°F. This will have a direct affect on
optimum product serving temperatures.
Due to various conditions such as extremely high kitchen temperature, high frequency of
tray activity breaking the air curtain 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 door closed for approximately 40 minutes. Always keep the door
closed except when actually unloading the refrigerator. Do not load the cabinet until the proper
operating temperature has been reached. (34°F-40°F)
2. Load the cabinet from the bottom up. Make sure the trays are pushed to the rear
wait. Optimum Air Screen operation requires that all trays be pushed all the way in
during unloading. Do not leave trays protruding into the air screen at the front of the
cabinet. After loading, close the door and allow inside air temperature to restabi lize to
(34°F-40°F).
3. Unload the cabinet from the top down.
4. Close the door during slow periods to extend the effective temperature maintenance
time.
Remember: The Air Screen Refrigerator must be at proper temperature
(34°F -40°F) before the door is opened.
The Air Screen Refrigerator will not lower food temperatures with the door
open.
This unit is equipped with an automatic condensate evaporator. To prevent water
spills, leave the unit plugged in with the door closed for a minimum of 90 minutes
after use.
THERMOSTAT CALIBRATION
The Air Screen Refrigerator has been calibrated at the factory and should not need any further
calibrations. If the Thermostat needs calibration, a qualified refrigeration technician should be
called into service.
DIGITAL THERMOMETER CALIBRATION _________________
The Digital Thermometer Calibration procedure is only to calibrate the thermometer to the actual
air temperature of the cabinet. This thermometer does not control the actual air temperature.
PROCEDURE:
1. Remove the screws that hold the upper control panel in place. Carefully pull out the
panel from the right side. Carefully let the panel hang.
2. Locate the thermometer on the inside panel you just removed. With a 3/8" wrench remove the two
10/32 nuts on the back of the unit and carefully remove the back plate . The adjustment
potentiometer is located in the upper right area of the thermometer.
3. Open the door and remove the inside right hand baffle and set aside. Behind this panel
you will locate the Digital Thermometer Sensor.
4. Immerse the sensor in a mixture of water and crushed ice to obtain 32°F.
5. With the sensor immersed in the water re -calibrate the thermometer using a small
Phillips head screwdriver to adjust the potentiometer. Turn clockwise to adjust the
temperature down (cooler) and counter-clockwise to adjust the temperature higher
(warmer). Wait 10 seconds for the adjustment to take place. Once adjusted re-seal the
potentiometer with clear nail polish to prevent calibration shift. Replace the back cover
plate and be sure to run the sensor wire through the notch in back plate.

Maintenance
Some casters are equipped with zerk grease fitting so that they may be
easily lubricated with a grease gun. Recommended lubrication is at least
Instructions
once every six months. Lubrication will be required every two weeks if
carts are cleaned with a hot water or steam cleaning system. Casters
with special bearings are recommended for frequent cart wash or steam
cleaning situations.
LATCHES
Check frequently to insure that all door latches are secure. Latches may
become "sticky" due to residue buildup from daily use and cleaning.
Lubricate latches regularly with WD-40, silicone spray, graphite or other
commercial lubricants for stainless steel products. Do not use oil.
PERIMETER BUMPERS
Vinyl which has been dislodged from the channel due to severe bumping
or scraping can be pried back into place with a common screwdriver.
