IV. INTENDED USE (continued) V. PRODUCT FEATURES (cont’d)
V. f - TRAY SLIDES:
Ten (10) pairs of removable tray slides are provided
standard at 4-1/2” spacing. Additional tray slides may
also be purchased for a total of no more than 15 pairs
at 3” spacing. Each tray slide can accommodate ei-
ther one (1) 18”x 26” or one (1) 12” x 20” pan. The
tray slides allow for individual pans to be pulled out
3/4 of their length without tipping. In addition, the side
wall air ducts are designed with two (2) tabs, which
act as a backstop, providing better air flow, which is
important to maintaining proper temperatures through-
out the cabinet.
V. g - WRAP-AROUND PERIMETER BUMPERS:
As the Air-Curtain refrigerator was designed to be mo-
bile, a full perimeter rubber bumper guard is included
to protect walls and doors during movement.
VI. ELECTRONIC CONTROLLER
VI. a - CONTROL OVERVIEW:
The Traulsen Air Curtain models are supplied standard
with an easy to use microprocessor control. It fea-
tures several important user functions, greatly enhanc-
ing the overall utility of the cabinet.
VI. b - CONTROL FEATURE - TEMP RECALL:
This feature allows the operator to display either the
actual internal cabinet air temperature (default), or the
desired “Set-Point” temperature (alternate).
ACTUAL: The factory default setting shows the actual
internal cabinet temperature and acts as a digital ther-
mometer. A momentary touch of the TEMP RECALL
button will recall the original dial setting. The display
will then automatically return the displaying the ac-
tual internal cabinet temperature.
SET-POINT: To display the set-point temperature in-
stead of the actual internal cabinet temperature, press
and hold the TEMP RECALL button for five (5) sec-
onds. The fourth digit on the display will flash either
“S” (SET) or “A” (ACTUAL) to indicate which mode is
active. To switch back again, repeat this step holding
the TEMP RECALL button for five (5) seconds.
VI. c - CONTROL FEATURE - ON/OFF:
This button has two uses, the first is to turn the unit
ON and OFF. The second allows for the temperature
display to be changed to indicate either degrees Fahr-
enheit or degrees Celsius.
To change between temperature scales, press and hold
the ON/OFF button for five (5) seconds. The display
will then switch from “dgF” to “dgC”. Repeat this
step to change the temperature scale again.

SUGGESTED PAN SIZING:
Traulsen has designed this unit to operate with either
18” x 26” or 12” x 20” pans. Generally, 12” x 20”
pans block air flow which leads to reduced unit per-
formance. While we strongly recommend the use of
18” x 26” rather than 12” x 20” pans, the latter may
still be used. However, when using 12” x 20” pans
these should be placed towards the top and bottom of
the unit to reduce the total blockage of air flow.

PRODUCT UNLOADING:
When unloading product from the Air Curtain
refrogerator, we recommend that this be done from
the top down.
V. PRODUCT FEATURES
V. a - CASTERS:
6” high casters are supplied standard for Air-Curtain
models. They are attached to 10-gauge stainless steel
corner plate reinforcements/stress pads. These are
shipped already installed on the unit for immediate use.
V. b - GRIPS & HANDLES:
For easy mobility, stainless steel recessed hand grips
are provided on the left and right sides. In addition, a
1” welded tubular push/pull handle is attached to the
rear of the cabinet.
V. c - ELECTRONIC CONTROLLER:
All Traulsen Air Curtain units manufactured after Janu-
ary 2003 include a 2-Stage electronic controller. Units
manufactured prior to that date were provided with
manual electromechanical controls
V. d - ON DEMAND DEFROST:
Traulsen Air-Curtain models are supplied with a mo-
mentary defrost cycle. It is located on the front con-
trol (see page 4), and by depressing the switch, the
unit will momentarily disable the compressor, the coil
and the fans. This “On-Demand Defrost” feature al-
lows proper defrosting of the accumulated condensa-
tion. Condensate is removed through use of an elec-
tric condensate evaporator drain pan.
V. e - CONDENSATE EVAPORATOR:
During the “On-Demand Defrost” cycle or the “Off
Cycle” of the compressor, the evaporator coil will de-
frost. The condensate from the evaporator coil flows
from the top of the unit down a drain in the back to a
condensate pan. Vapor escapes through the back grill.
The vapor can sometimes be visible and should be
considered a normal operating condition.
Proper attention should be given to defrosting your
unit. Every “event” or time the unit is used with the
door open, the coil will build-up ice. This reduces the
effectiveness of the overall operation of the unit.
