1.2 Product Trays

There are 3 product tray sizes. See Appendices A and C for specific product volumes and recommended holding sizes and times. Use the tray that is designed for the specific product described below:

A.1/3-size plastic tray – Holds meat and egg products that are grilled (hamburger patties, bacon, eggs, sausage, etc.) There are two important procedures to remember when storing grilled products:

•The product should not be drained when picked up from the grill.

•The product is stacked when placed in the proper tray. 10-1 and sausage patties can be stacked up to six high. Eggs (except scrambled), grilled chicken and 4-1 patties can be stacked up to three high.

B.1/2-size wire tray – holds fried products (McNuggets, McChicken, Filet-O-Fish, etc.) Remember this important procedure when storing fried products:

•Fried products are to be placed on the wire rack. The rack should be placed on a crumb tray. No tray liners are required for these trays.

C.Full-size plastic tray – holds baked products (biscuits, muffins, etc.) Follow these procedures for baked products:

•After the biscuits have been removed from the biscuit oven, remove the wrapper and open the cardboard box.

•Put a tray liner in the tray and slide the biscuits onto the liner. The biscuit trays can hold up to 30 frozen biscuits, 20 scratch biscuits or 20 muffins.

Important Operational Tips

When placing a tray into the cabinet, make sure the slot line on the tray handle lines up with the edge of the slot.

Discard cracked or damaged trays.

When removing portions from a tray, slide the tray only as far as needed, then quickly return the tray to the slot line.

1-3

1.3 Install Grill Clip

The grill clip is shipped in the accessory package and is designed to hold the 1/3-size grill tray. It attaches to the grill to make transfer from the grill to the UHC faster and safer.

•Position the front of the grill clip under the lip of the grill.

•Lower the back of the clip until the grooves rest over the grill bar. The grill clip should firmly seat on the front of the grill. If the clip doesn’t fit snuggly, simply loosen the four nuts under the clip and slide it in or out as needed to tighten against the bar. Tighten the nuts after the clip is properly adjusted.

The grill clip attaches to the grill and holds grilled product in a UHC tray, making transfer to the holding cabinet easier.

1.4 Installation of 4” Legs

CAUTION

Use caution when handling the cabinet or tilting the unit to/from the floor to install the legs. Maneuvering the cabinet should be accomplished by at least two people.

A.Carefully place the Universal Holding Cabinet on its right side (direction is determined with you facing the front of the unit), exposing the base of the cabinet.

B.Mount the leg pads to the bottom of the base using the 16-¼"-20 x ½" long screws and lockwashers provided.

C.Screw the leg into the mounted leg pad until fully tight.

D.Carefully turn the UHC upright until the unit stands on its legs. Perform Step 2, Power Up.

IF THE UHC IS INSTALLED WITH THE COUNTERTOP OPTION, ENSURE THE AREA WHERE THE UHC BASE AND COUNTERTOP MEET IS PROPERLY SEALED WITH A FOOD GRADE TYPE SEALANT.

3 Operational Overview

The Universal Holding Cabinet (UHC) has either four slots that can hold up to three trays of product per slot or two slots, which hold up to three trays. Each slot has a controller that indicates the holding time and product selection for each tray position.

Universal Holding Cabinet (UHC)

The operator enters information into the controller via the display and keypad shown below. Each product selection has a temperature setpoint and product holding time. All product timers run independently. The

slot temperature is controlled by the temperature setpoint of the leftmost product entry in each slot as viewed from the front of the cabinet. Product selections that have a holding temperature different that the leftmost product selection will not be available for entry into that slot’s configuration.

Most UHC’s have a front and rear display for each slot. All operator mode selections can be made from either display. Program changes can only be made from the front display. A Special Point of Distribution (SPOD) cabinet has only a front controller for each slot.

UHC Controller (Front Display and Keypad)

Timer keys (Left, Center, and Right) start and stop the timer associated with each tray position. The timer keys also turn off audible alarms.

Displays (Left, Center, and Right) show product selection and holding time for each tray position. The displays also provide programming information in program mode.

4 Operator Mode

Operator Mode is the normal operating mode of the controller when all slots are at the proper temperature and no alarm conditions exist. Product information and holding time is displayed.

4.1 Display of Product Information

In Operator Mode the slot display indicates the following:

1.The product selection for a tray location.

2.The holding time remaining (in minutes) for active timers.

An active timer alternately displays the product selection and the time remaining. Inactive timers display only product selection.

4.2 Product Information and the Use First Display

The Operator Mode indicates product selection and holding time status by changing the display intensity.

The “Use First Display” indicates the product with the least amount of holding time remaining. There are two levels of display intensity used to indicate product status.

1.Brighter level of display intensity and running dots indicate the “use first” product selection.

2.Lower level of display intensity indicates:

a.An active timer that is not the product selection with the least holding time remaining.

b.An inactive timer where only the product selection is displayed.

5.4 Buffer Timer (cont.)

When the "Use First" tray of a product is placed in the cabinet, the product timer is activated by pressing the corresponding timer key. The display immediately indicates the maximum holding time for the product and changes to Display Intensity three (brightest). If the timer key is pressed within 3 seconds of activating the timer, the product holding time will decrease by 5 minutes for each key press. If no timer key press occurs within 3 seconds, the display then alternately displays the remaining holding time and product mnemonic.

The Timer Display Time (TIMR TIME) and Product Display Time (PROD TIME) values determine how long (in seconds) that each message is displayed. Default settings for these values are 5 seconds and 1 second respectively.

To decrease the preset time, the holding time for each product, press the timer key and the displayed time will decrease in 5-minute increments each time the key is pressed. The timer key must be pressed within 3 seconds. If you wait longer than three seconds, the timer will reset. Preset times are the established holding times for each product. The Buffer Timer Feature is extremely useful when transferring product from another holding cabinet.
