The cabinet contains (2) Dixell controllers, where only the visible controller is required for user interface. The
set points for each are listed below.
IRAC15 C1 Controller (Face): 34° F
IRAC15 C2 Controller (Inside): 20° F
Note: The Dixell controller settings have been carefully configured to optimize the performance of the
cabinet. See the notes below regarding possible outcomes if any deviation from the factory set points is made.
-Adjusting the set temperature of the cabinet to a lower setting may make the stored food product more sus-
ceptible to freezing when storing the food product for extended periods of time without open door operations.
-Adjusting the set temperature of the cabinet to a higher setting may affect open door performance.
Please contact the service department if there are any questions or if further customization is required.
CONTROLLER SETTINGS

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.

GENERAL MAINTENANCE INSTRUCTIONS
CASTERS
Some casters are equipped with Zerk grease fittings so that they may be
easily lubricated with a grease gun. It is recommended that all caster bear-
ings need to be lubricated with a high quality multi-purpose grease that has
good extreme pressure and anti-wear characteristics, as well as withstands
temperature range that fits the application requirements. Wheel and swivel
bearings last longer if lubricated regularly.
It is recommended to lubricate the bearings at least once every six months.
Lubrication will be required more frequently if carts are cleaned with a hot
water or steam cleaning system.
HINGES
Your cart doors and hinges have been factory aligned to assure positive latching and smooth action. If doors
are removed for cleaning, we recommend that they be put back on the same cart to assure the best possible
alignment and operation. Correct hinge alignment is based on the correct gasket compression of 1/32” to 1/16”.
The hinges also need to be aligned with the door strike to accommodate the locking cylinder. To adjust hinge
alignment, it is recommended to use assistance. It is recommended to loosen the bolts on the cabinet side of
the hinge and apply pressure inward on the door to form the seal on the gasket. Align the door as needed and
while maintaining pressure, tighten the bolts.
LATCHES
Check frequently to insure that all door latches are secure. Latches may become “sticky” due to residue build-
up from daily use and cleaning. Lubricate latches regularly with WD-40, silicone spray, graphite or other com-
mercial lubricants for stainless steel products. Do not use oil. If latches require adjustment, it is recommended
to use assistance. First, loosen the screws on the latch. Next, align the latch to compress the seal of the gasket
by applying pressure to the door while the screws are still loose. Lastly, while maintaining pressure to the door,
tighten the screws on the latch.
PERIMETER BUMPERS
Vinyl which has been dislodged from the channel due to severe bumping or scraping can corrected by carefully
utilizing a screwdriver to guide the rubber bumper back into the bumper channel.
DRAINING CONDENSATE PAN
Depending on environmental and operating conditions, manually draining the condensate pan may be neces-
sary. It is recommended that the condensate levels in the pan be checked regularly to gauge the necessary
frequency, if needed, of manually draining the pan. It is also recommended that the condensate level be
checked prior to transport of the unit to prevent possible spillage.
To manually drain the condensate pan, open the valve located on the underside and towards the rear of the
unit. Rotate the valve lever counter-clockwise until it stops (parallel with tubing). Once condensate pan has
been emptied, turn valve lever clockwise until it stops (perpendicular to tubing).
