IV. INTENDED USE (continued) V. PRODUCT FEATURES (cont’d)

IV. c - 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.

IV. d - 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.

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.
