temperature inside the cabinet

3-2 6 Blower Motor Used to recirculate the hot humid air throughout the
cabinet; there are two blower motor assemblies in the
cabinets

3-2 7 Heater Two, open-resistance, wire type heaters that provide
heat throughout the cabinet; a standard full sized 120
VAC unit will have 1000 watt heaters; a standard full
sized 240 VAC unit will have 1500 watt heaters;
a standard 120V, HHC-903 unit will have 750 watt
heaters

current exceeds the rated value; the fuse provides
an overload protection for the electrical components;
to remove the fuse, twist and pull the cap; the fuse is
used only on the 120V/2000 watt units

3-3. START-UP

Model HHC-90X/Model HC-5/15

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

1. To 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.

Step 1

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. OPERATION WITH
PRODUCT

3-5. VENT ADJUSTMENT

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

2. Serve the product f rst 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.

To avoid burns, allow the unit to cool before cleaning.

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

4. Take the trays to a sink and clean them thoroughly.

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

and water.

3-6. CLEANING
PROCEDURES
(Continued)

Step 6

6. Wipe the control panel with a damp cloth. Do not splash
water around the controls.

7. Clean the exterior of the cabinet with a damp cloth.

Do not use steel wool, other abrasive cleaners or
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.

Step 8

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

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

11. Leave at least one door open over night to allow the unit to
thoroughly dry out.
