CONNECTION

4. Open doors and remove packing from behind racks and
the water pan in the bottom of the unit.

5. Peel off any protective covering from the exterior of the
cabinet.

6. The cabinet is now ready for location and use.

Place the humidified holding cabinet in an area that allows
the doors to be opened without interference of loading and
unloading product. Also, keep the unit level for proper
operation.

No minimum clearances are required for the rear and sides
of the cabinet.

T o avoid electrical shock, the cabinet must be adequately
and safely grounded (earthed) according to local electrical
codes, and this appliance must be equipped with an exter­nal circuit breaker which will disconnect all ungrounded
(unearthed) conductors. The main power switch on this
appliance does not disconnect all line conductors.

(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

If the electrical supply to the unit is a cord and plug, then the
electrical receptacle, for the plug, must be easily accessible.

Refer to the table below for the electrical ratings for the
HHC-980 and 983.

CONNECTION 100 psi (690 kPa), water connection. A water conditioner or filter ,

and a shut-off valve in the supply line is recommended.

Follow these steps when making the water supply connection:

1. Flush incoming water line.

2. Using pipe joint compound on the threads, screw the brass
elbow into the fitting on the left side the cabinet. Using a 1 inch
wrench, secure the fitting nut while tightening the elbow .

Figure 2-1 Figure 2-1.

3. Connect 1/4 inch tubing to the female quick-disconnect fitting,
supplied with the cabinet. Figure 2-2

4. Attach female quick-disconnect to the male quick-disconnect
on the elbow .

Figure 2-2

This unit as manufactured requires the installation of an appro­priate back-siphoning device (as per National Plumbing Code
ASA-A40:8-1955) to be connected to the water inlet line.
This device to be connected in accordance with basic plumb­ing code of the Building Officials and Code Administrators

Before using the humidified holding cabinet, completely
clean the unit as described in the Cleaning Procedures
Section of this manual.

1. Plug unit into electrical receptacle, or turn on wall circuit
breaker . With the POWER switch turned to OFF the
display shows “POWER OFF .”

Even though POWER switch is off it does not dis­connect all electrical supplies to the controls.
Unplug power cord, or turn off wall circuit breaker
before servicing any electrical components, or
electrical shock could result.

2. Connect or turn on water supply.

3. Turn the power switch to ON, and the display
shows “Pizza Hut”, then “HHC-983”, or “HHC-980”.

4. Press the TEMPERA TURE button to set the desired
cabinet temperature. While the LED is flashing, press
the UP and DOWN buttons until the desired tempera­ture shows in the display . Preset at 175

o

F (80o C).

5. Press the HUMIDITY button to set the desired cabinet
humidity (OFF , then 10% to 90%). While the LED is
flashing, press the UP and DOWN buttons until the
desired temperature shows in the display . Preset at
28%.

6. Allow the unit to preheat for about 1 hour prior to
placing product in the cabinet. This allows the interior
conditions to stabilize.

Model HHC-980/983

3-4. OPERA TION WITH 1. The LEDs above the TEMPERATURE and HUMID-
PRODUCT ITY buttons go out when the desired temperature and

humidity are reached inside the cabinet.

The minimum holding temperature for potentially

o

hazardous product is 150

F (66o C). Also, the
cabinet product load capacity for the full size units
is 375 lbs. (170 kg.), and 125 lb. (57 kg.) for the
half-sized units.

2. Place boxed product into cabinet.

Hold Times:

Dinner size pizzas = 30 minutes

Personal pan pizzas = 30 minutes

Wings = 2 hours

If the float switch in the water pan senses low , or no
water after 5 minutes, “WATER PAN NOT
FILLING, CHECK WATER SUPPL Y” shows in the
display.

Hint: Open the doors only as necessary to load and unload

product. This helps to keep the interior conditions
constant and saves energy .

3-5. CLEANING Daily:
PROCEDURES 1. Turn all controls off and disconnect electrical supply.

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