1. Tray slide assemblies are easily
removed without tools for cleaning.
Simply lift up and pull out. The tray
slides may be hand washed or run
through an automatic washer.
2. If applicable, vinyl trim or laminate should be washed with a chlorine-free
detergent and water. Rinse thoroughly with clear water and allow to dry.
Never use abrasive cleaners, waxes, car polish or substances containing
strong aromatic solvents or alcohol. Caution: When using solvents, it is
essential that proper precautionary measures be observed. Refer to
solvent manufacturer's instructions. Use of direct steam/hot water
cleaning at temperatures above 190°F may result in "bubbling" or
loosening of vinyl adhesive.
3. To clean stainless steel surfaces use only cleansers, detergents,
degreasers, or sanitizers that are certified to be "chloride-free" and
"phosphate-free," and cleansers, degreasers, or sanitizers only in the
recommended concentrations. DO NOT exceed recommended
concentrations or mixing ratios. After cleaning and sanitizing, rinse all
exposed surfaces thoroughly with large amounts of clear water. Wipe off
any standing liquid or residue from all horizontal surfaces in corners, or
near edges.

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 wall.
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 restabilize 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.
[A] 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.
[B] 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. Place thermometer in geometric center of the cabinet. Turn power on and close the door.
Allow cabinet to operate for 45 minutes. After this time check to see if the digital display
temperature matches the thermometer you placed in the center of the cabinet. If not,
calibration is necessary. If the temperature matches, calibration check is complete.
WARNING Turn off power before removing control panel.
2. 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.
3. Locate the digital thermometer on the inside panel you just removed. The adjustment
potentiometer is located in the lower back area of the digital thermometer.
4. Turn power back on making sure no wires are pinched.
5. Re-calibrate the digital thermometer using a small jeweler's screwdriver to adjust the
potentiometer. Turn counter-clockwise to adjust the digital temperature down (cooler)
and clockwise to adjust the digital 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.
WARNING Turn off power before reinstalling control panel.
6. Replace the back cover plate and be sure to run the sensor wire through the notch in
back plate. Turn power off before replacing the control panel.

Operations

[A] CASTERS
Some casters are equipped with zerk grease fitting so that they may be
easily lubricated with a grease gun. Recommended lubrication is at least
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.
[B] 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.
[C] PERIMETER BUMPERS
If applicable, vinyl which has been dislodged from the channel due to
severe bumping or scraping can be pried back into place with a common
screwdriver.
