2-3. LOCA TION

2-4. ELECTRICAL

CONNECTION

The unit should be placed in an area where the doors can be opened
without interruption and loading and unloading of product is easy . For
proper operation, the cabinet must be level.

To avoid damage to the unit, do not set anything on top of the
cabinet that might close the vent holes.

The heated holding cabinet is available from the factory as a
120 VAC or 240 VAC unit for domestic use and as a 240 VAC unit
for foreign use. The data plate, located on the side of the module, will
specify the correct electrical supply . The unit requires a grounded
receptacle with a separate electrical line protected by a fuse or circuit
breaker of the proper rating. For European markets, verify the
electrical plug meets the proper electrical rating and country type. See
local authorities for proper standards.

T o avoid electrical shock, the cabinet must be adequately
and safely grounded (earthed) according to local electrical
codes.

(FOR EQUIPMENT WITH CE MARK ONL Y!)
T o prevent electric shock hazard this appliance must be
bonded to other appliances or touchable metal surfaces in
close proximity to this appliance with an equipotential
bonding conductor . This appliance is equipped with an
equipotential lug for this purpose. The equipotential lug is
marked with the following symbol

Step 1

Model HHC-900/902/903/906/908

Before using the heated holding cabinet, the unit should be thor­oughly cleaned as described in the Cleaning Procedures Section
of this manual.

1. T o put the unit into operation, move the power switch to the ON
position. The power light should now be illuminated and the
blowers should be in operation.

2. Remove the water pan and put approximately 1" of hot water
in the pan. Return the pan to its location.

Be sure to push the water pan in as far as it will go so that it does
not block air from the thermometer and thermostat capillary tubes.
This will ensure proper operation of these components.

Step 2

3. Set the thermostat at #7 or approximately 180°F (82°C). When
the heat light goes out, the unit is ready for operation.

The unit should take approximately 25-35 minutes to heat to
temperature during start up. Be sure that the temperature light
goes out before loading with product.

3-4. OPERA TION WITH
PRODUCT

3-5. VENT ADJUSTMENT

1. Place the hot product on bun pans and insert between the cabinet
racks.

2. Serve the product first that has been in the cabinet the longest.

3. In order to maintain a constant temperature, open the doors only
as necessary to load and unload product.

As mentioned in the Operating Controls and Component Section,
the vent system limits the humidity level of the cabinet. The vent
adjustments are very easy to follow .

The vent setting corresponds to the number of trays of product. With
one tray of product, set the vent at No. 1. With two trays of product,
set the vent at No. 2 and so on.

3-6. CLEANING
PROCEDURES

Step 3

1. Turn all controls to the OFF position.

2. Disconnect the electrical supply to the cabinet.

T o avoid burns, allow the unit to cool before cleaning.

3. Open the doors and remove all trays from the cabinet.

4. T ake the trays to a sink and clean them thoroughly .

5. Remove the water pan and clean it with a soft cloth, soap, and

water.

cleaners/sanitizers containing chlorine, bromine, iodine
or ammonia chemicals, as these will deteriorate the
stainless steel material and shorten the life of the unit.

Do not use a water jet (pressure sprayer) to clean
the unit, or component failure could result.

8. Open the doors and remove side racks. Clean the racks with
soap and water.

9. Clean the interior of the cabinet thoroughly with a cloth and soap
water.

Step 8

10. Put the side racks and water pan back into the cabinet.

Programming T emperature and Timers

1. Press and hold until "Prog” shows in the display

2. Press to change the flashing setpoint temperature.

If “LOC” shows in the display at this time, the programming
controls are locked and must be unlocked. See Special
Program Mode Section.

3. Press and release to program the timers. Press any of

the timer buttons, on either side of the unit, and when they are
flashing, use to set the timer in minutes and seconds. If a

timer is flashing on one side of the unit, the corresponding timer
on the other side of the unit also flashes. For example, if timer
#2 on the front of the unit is flashing, #2 on the rear of the unit
also flashes. So, both front and rear timers are programmed at
the same time.

More than one timer can be programmed at the same time if
they are to be programmed with identical times. Just press the
timers to be programmed and when they are all flashing, use

to set the time in all timers. Again, both front and rear

timers will be programmed.

4. Press and hold to exit the Program Mode and all

settings are now programmed.

SPECIAL PROGRAM MODE

This mode consists of:

• Fahrenheit or Celsius Programming

• Initialize System - One button programming for times and
temperatures

• Probe Calibration

• Locking or Unlocking Programming

• Outputs T est

1. T urn power switch OFF and press and hold until “SP”
shows in the display , followed by the software version.

6. Use to set the displayed temperature to match the actual
temperature inside the unit.

7. Press and release twice and “P= L or U” shows in
the display . “P=L” means Locked and the setpoint
temperature and timers CANNOT be programmed. “P=U”
means Unlocked and the setpoint temperature and timers CAN
be programmed. Use the to toggle the display from

“P=L” to “P=U” or vice-versa.

8. Press and release and “OP” shows in the display .

4-2. ERROR CODES ­ COUNTDOWN TIMERS

The CDT controls have built-in diagnostics which display error
codes on the display . This section describes the codes.

DISPLAY CAUSE PANEL BOARD CORRECTION

“E-4” Control board overheating T urn switch to OFF position, then turn

switch back to ON; if display still shows
“E-4”, the board is getting too hot; check for
signs of overheating behind the control
panel; once panel cools down the controls
should return to normal; if “E-4” reappears,
replace control board

“E-5” Unit overheating Turn switch to OFF position, then back to

ON; if “E-5” reappears, the heating and
blower circuits should be checked, along with
the temperature probe; once the unit cools
down, the controls should return to normal; if
“E-5” reappears, replace control board

“E-6” T emperature probe failure Turn switch to OFF position, then back to

ON; if “E-6” reappears, the temperature
probe should be checked; once the
temperature probe is repaired, or replaced, the
controls should return to normal; if “E-6”
reappears, replace control board

“E-41” Programming failure Turn switch to OFF position, then back to

ON; if “E-41” reappears, the control
should be re-initialized (see Operating
Controls - Countdown Timer Section); if
“E-41” reappears, replace control board

“E-50” RAM failure Turn switch to OFF position, then back to

ON; if “E-50” reappears, replace control
board

“E-51” NOVRAM failure Turn switch to OFF position, then back to

ON; if “E-51” reappears, replace control
board

“E-53” EPROM failure Turn switch to OFF position, then back to
