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 rememb er 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 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 tw o 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

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.

10 Product Selection For Each Slot
10.1 Program Mode
The following is the correct locations to program the slot controls based on the configuration of trays
and products:
• 1/3-size plastic tray – Since each slot can accommodat e 3 trays, all displays can be p ro grammed
for a product. Remember, the temperature parameters established by the left display product will
be in effect for the entire slot, but the timing and product settings can be different for each
display within a slot.
• 1/2-size plastic tray with wire insert – Since each slot can only accommodate two trays, the left
and right displays will be used for controlling/monitoring the products. The center display
should be voided by selecting NONE; the left and right displays should be active with selected
product. Again, the temperature parameters established by the left display product will be in
effect for the right display but the timing and product settings can be different for each display
within a slot.
• Full-size plastic tray – Since each slot can accommodate one tray, the center display will be
used to establish product parameters. The center display establishes the product parameter for the
slot. The left and right displays should be voided by choosing NONE with only the center
display active with the selected product.
Program Mode is used to select the products for each slot location. All selections are accomplished
through simple PAGE and MENU selections. Each slot position has a page of configuration menus.
The top slot in the cabinet is Slot 1. The PAGE key is used to select slots 1 – 4. The MENU key
selects the configuration menu items (meal and tray location). Th e Up/Down arrow keys are used to
select the available product selections for each meal. To enter the pro gram mode, press and hold the
MENU key for at least 5 seconds. The display will indicate the PROG MODE message.

14 Tests
14.1 Transformer
1. Disconnect power to cabinet. Remove side and top panels, unless stacked. If stacked, see the
service procedures for access instructions.
2. Mark for re-assembly, then remove the two bottom leads. Connect an AC meter across the
outside terminals of the secondary. Apply power and note the voltage. If voltage is
approximately 16 VAC, the transformer is operating normally. If zero or incorrect voltage is
measured, measure the input voltage at the top two terminals (primary). The acceptable input
voltage range is 177 to 264 VAC.
14.2 Master Control Board
Input Power
1. Disconnect power to the cabinet. Remove side and top panels unless stacked. If stacked, see the
service procedures for access instructions.
2. Visually check all terminals and connections for loose or disconnected wires.
3. Apply power and measure AC voltage to board on connector CN1. Correct measurement is 16
volts across the two outside connectors and 8 volts from either outside connector to the center
connector.
14.3 RTD/Master Board
1. Normally only one or two plates will be suspect. To isolate between a defective RTD, bad wiring
connection or defective master board, first perform the heater plate test described in section 14.7.
2. If the plate tests OK (heater and RTD ), isolate further by swapping the l eads (heater and RTD)
from the suspect slot with a slot that operates correctly.
3. If both slots operate correctly after swapping, a poor wire connection is the probable c ause of the
malfunction. (Reconnect the wires to their original slots and retest.)
4. If the original slot continues to malfunction with swapped leads, the master board is defective.
5. If the malfunction moves to the other slot, the heater plate/RTD assembly is defective.
NOTE: After testing, reconnect all leads to their original positions.
14-1
14.4 Master Board/Display Driver
1. To isolate between a defective master board or display driver, disconnect the front and rear
ribbon cables (FC1 and FC2) and the CN2 connector on the suspect displa y driver. Disconnect
the front and rear ribbon cables and the CN2 connector on the nearest display driver, which
operates correctly.
2. Connect the connectors from the suspect display driver to a known good display driver and test
the operation. If the malfunction continues, replace the master board. If the malfunction is
corrected, replace the defective display driver.
NOTE: After testing, reconnect all connections to their original positions.
14.5 Shorted Triac
1. Turn the suspect slot off and measure voltage from the white terminal block to the top (black
lead) heater plate. Also, measure voltage to the bottom heater plate. With slot off, there should be
no line voltage. If the triac is shorted, you will measure AC line voltage. If the triac is half
waving, you will get DC voltage of approximately one-half the line AC voltage. Also, with the
slot off, measure the slot temperature. If the slot is heating, it is miswired or the master control
board is defective (shorted triac).
14.6 Display Driver/Display Isolation Test
1. On stand-alone units, disconnect power to the cabinet and remove side and top panels. If unit is
stacked, see service procedures for instructions on accessing the top panel.
2. Disconnect CN2 connector on the suspect display driver. Apply power. The selected display will
indicate Disp Test Mode. (Note: All slots below the selected slot will not operate.) Press
each functional button on the selected display, starting with the timer key at the left. Each button
must be pressed in sequential order, starting at the left on the front display and continuing to the
rear display on all slots. After all buttons have been pressed, each LED display segment should
illuminate sequentially.
3. If the unit does not perform as described in step 2, isolate between a bad display or display driver
by connecting the ribbon connector form the suspect display to one or the know good display
drives and repeat the test.
NOTE: There is no output from the master control board during this test. If t he unit does not
operate as described in step 2, the problem cannot be the master control board.
14-2
14.7 Heater Plate
1. Disconnect power to the cabinet. On stand-alone units, remove side and top panels. On stacked
units, see Service Procedures for instructions on accessing the top panel.
2. Disconnect the black heater lead and the two RTD leads (brown and red) of the suspect plate
from the master board. Measure resistance of the heater from the black lead to an y terminal on
the white terminal block. Resistance should be 140-150 ohms.
3. Measure resistance across the brown and red RTD leads. Resistanc e must be within a range of
104-148 ohms. Resistance at room temperature is approximately 107 ohms. See chart on Page
18-5 for resistance at different temperatures. If either resistance is incorrect, replace the heate r
plate.
14.8 Display Meanings
1. SLOT TEMP HIGH OR SLOT TEMP LOW and no audible alarm. This is normal when
the slot is changing temperature in association with a menu change.
2. LLLL means the RTD indicates a temperature below 50°F (10°C). Unit will automatically heat
at 20 percent until temperature is above 50°F (10°C), then operate normally.
3. HHHH means RTD indicates the temperature is above 255°F (124°C), but below "Open" circuit
resistance, which causes SENS ALARM.
4. UHC VERSION _ _ _ (version numbe r will vary) appears for five seconds when the unit
is turned on. This is normal. If the UHC VERSION _ _ _ stays in the display, the normal
cause is 120 VAC is applied instead of the nominal 200 to 250 VAC.

15 Service Procedures
15.1 Removing/Replacing Shelf Components
DANGER!! Failure to disconnect the power supply before servicing could result in serious
injury or death. The cabinet power switch DOES NOT disconnect all incoming power to the
cabinet.
1. Turn the UHC off, disconnect the power supply and allow the unit to cool (approximately 60
minutes).
2. Use a #2 Phillips-head screwdriver to remove two
#10 truss-head screws from each side of the unit (Fig.
1).
3. Remove the side panels and set aside, being careful
not to mar the panel finish.
Fig. 1. Removing side panel.
4. Removing the side panels allows access to display
driver boards (removable by disconnecting the wire
harnesses and removing the securing screws), fascia
mounting screws and slot mounting screws (Fig. 2).
5. Use a 5/16” nut driver to remove the four cabinet
screws holding the equipment shelf in place. The
screws are located on each side of the unit, near the
top corners of the inner panel.
6. Use 5/16” nut driver to remove the two #10-32 hex-
head screws from each side of the front fascia.
7. Pull the front fascia out (you may use the Production
Chart Holder as a grip to free the fascia from the
cabinet) and up to reveal the front edge of the
equipment shelf. (It is not necessary to disconnect the
switch wiring. Fig. 3)
NOTE: For accessibility of the fascia, the top of
the unit may be removed if the configuration is
either a single stand-alone unit or the top unit of
a stacked arrangement.
8. Grab the edge of the shelf and pull out slightly.
Remove the wire and wire harnesses to free the shelf.
Mark each wire for reassembly. Pull the shelf until it
engages the stops. Place the fascia on top of the shelf
(Fig. 4-5).
Fig. 2. Side panel removed.

Appendix B: Cleaning and Preventive Maintenance
After Each Use – Clean Trays/Racks
1. Remove all plastic and wire trays. Take trays/racks to the sink for cleaning.
2. Clean trays by washing in a hot McD All-Purpose Super Concentrate (APSC) (HCS) solution
drawn through the sink proportioner or mix 0.3 fl. McD APSC (HCS) for each gallon of solution.
Rinse trays/racks thoroughly under hot water.
3. Sanitize trays/racks by dipping in McD Sink Sanitizer (HCS) solution, (one pack per 10 gallons
of water) or McD Sanitizer (HCS) solution (four packs per 10 gallons of water), for at least 1
minute. Remove from sanitizer solution and allow to air dry.
Daily – Clean Cabinet
1. At the end of the operating day, turn unit to Clean Mode (see Clean Mode, Section 7.2 on Pa ges
7-2 — 7-3).
Note: Do not use McD Sink Sanitizer (HCS) to clean the exterior of the Universal Holding
Cabinet.
2. Let the unit cool until SAFE to CLN is displayed. Use brush to remove any remaining
buildup on the slot surface by pushing the particles out the opposite end of the cabinet.
Note: Use only the cabinet cleaning brush to clean the cabinet slots. Wire brushes, abrasive
pads, or metal scrapers will permanently damage the surface of the cabinet slot.
Note: Do Not use any other cleaner than McD (APSC)(HCS). Using other compounds may
result in damage to control components.
3. With the cabinet cleaning brush push all loose particles out the opposite end of the cabinet.
4. Use a wet, clean/sanitized towel and the cabinet cleaning brush to clean each slot. Clean the
bottom and top surface of each slot.
5. Wipe clean all exterior cabinet surfaces with a clean, sanitized towel that has been soaked in
McD ASPC (HCS).
6. Turn the unit off.
18-2
Weekly – Cabinet Slots
Calibrate the top and bottom plates in all four UHC slots by performing the following procedure
with the slots clean, empty and at operating temperature for at least 30 minutes.
1. Press the temperature key (See Displ aying Slot Temperatu re Information on Pa ge 8-1) to ensure
the setpoint temperature was reached consistently for the 30-minute minimum.
2. Slide the Atkins sensor into a slot with the sensor facing upward to measure the top heater plate
or downward to measure the bottom heater plate. Move the senso r to the center of the plate. To
get an accurate reading, the sensor must be within ± 1 inch of the center of the plate.
3. Allow three minutes for the sensor to stabilize.
4. Read the temperature on the pyrometer. The temperature on the p yrometer should be within ±
5°F (± 3°C) of the temperature read in the UHC. Press the temperature k ey once to get the slot
top plate within tolerance ± 5°F (± 3°C), check the next plate/slot. If the reading is out of
tolerance, perform the following procedure:
• Enter the program mode by pressing the Menu key for at least five seconds. Press the page
key until View____PAGE appears in the slot controller display.
• Press the Menu key until SECR Lock _ _ _ _ is displayed. Enter the Service Code, 2 4 7
using the UP and Down arrow keys.
• Press the Page key to display the slot to be corrected. (For slot 1, the display will read
SLOT___1.)
• Press the Menu key until you get to the top or bottom plate for correction. (For a top plate the
display should read TOP OFST 0).
• Press the Up or Down arrow key to enter 1°F/C at a time until the correct offset is achieved.
Example: If the RTD measures 150°F (65°C) and you measure 155°F (68°C), enter +5°F
(+3°C) to achieve the offset. If you measure 145°F (63°C) and the RTD measures 150°F
(66°C), enter –5°F (-3°C) to achieve the offset.
Annually – Clean Air Exhaust Fans
CAUTION
Failure to disconnect the power at the wall power supply could result in serious injury or
death. The cabinet power switch DOES NOT disconnect all incoming power to the cabinet.
This service should only be performed by qualified service personnel.
CAUTION
Use caution when handling the cabinet. Each cabinet weighs over 200 pounds.
Maneuvering/handling the unit should only be attempted with at least two people.
18-3
Annually – Clean Air Exhaust Fans (cont.)
1. At the end of the operating day, place the unit in the CLEAN MODE (see Clean Mode,
Pages 7-2— 7-3).
2. Perform all daily maintenance requirements.
3. Disconnect power at the power source before beginning yearly maintenance. See caution
above.
4. With a Phillips screwdriver, remove the two screws in each side panel. Set the screws aside.
5. Remove the side panels from the unit.
6. Gain access to the air exhaust fans as follows:
a. If the cabinet is a single stand-alone unit or the top unit of a stacked arrangement, us e a
5/16” socket driver to remove the four screws hol din g the c abinet top i n place. R emove
the cabinet top. Skip to step 10.
b. If the cabinet to be serviced is the bottom unit of a stacked arrangement, use a 5/16”
socket driver and remove the four screws holding the equipment shelf in place. The
screws are located on each side of the unit, near the top corners of the inner panel.
7. Use a 5/16” nut driver to remove the two #10-32 hex-head screws from each side of the
front fascia.
8. Pull the front fascia out. It is not necessary to disconnect the switch wiring.
9. Remove wire and wire harnesses as need ed to free the shelf. Mark each wi re distinctly for
re-assembly. Grab the edge of the shelf and pull straight out until the shelf engages the
stops. Place the fascia on top of the shelf.
10. Wipe down the blades of the air exhaust fans with a cle an cloth, dampened with McD AS PC
(HCS). Take care not to touch any electrical connections with the cloth. This procedure

Appendix D: S.O.C. for the Universal Holding Cabinet (UHC)
The procedure for the Universal Holding Cabinet when us ed for FRIED PRODUCTS is similar to
our current procedure. The only difference is that the fried product is held in a wire rack that goes in
a crumb tray and placed in the pre-designated slot in the cabinet. No tra y liners are required for
these trays.
The procedure for the Universal Holding Cabinet when used for GRILLED PRODUCTS is also
similar to our current procedure, except for:
• The product should not be drained when picked up from the grill.
• Use a tray liner for all grilled products.
• The product is stacked when placed in the proper tray. 10-to-1 and sausage patties can be
stacked up to six high. Eggs (except scrambles), grilled chicken and 4-to-1 patties can be
stacked up to three high (See Appendix G, Page 18-9).
The procedure for the Universal Holding Cabinet when used for BISCUITS is as follows:
• After the biscuits have been removed from the biscuit oven, remove the wr apper 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.
