RECOMMENDED CONTROL SETTINGS AND HOLDING TIMES

Chefs, cooks and other specialized food service personnel employ varied methods of cooking. Proper holding

temperatures for a specic food product must be based on the moisture content of the product, density,

volume, and proper serving temperatures. Safe holding temperatures must also be correlated with palatability in

determining the length of holding time for a specic product. The following are some recommended settings and

holding times for products generally held in the cabinet.

See the control label or the Temperature and Humidity Control Operation section of this manual for instructions
on changing the presets. Temperatures indicated on the cabinet display do not always match the product

temperature.

Pizza 1 (T-175°F, H-10) 1 Hour

GENERAL INSTALLATION INSTRUCTIONS

This equipment is designed and sold for commercial use only by personnel trained and
experienced in its operation and is not sold for consumer use in and around the home nor
for use directly by the general public in food service locations.

All shipping containers should be checked for freight damage both visible and concealed. This

unit has been tested and carefully packaged to insure delivery of your unit in perfect condition. If
equipment is received in damaged condition, either apparent or concealed, a claim must be made
with the delivering carrier.

Concealed damage or loss - if damage or loss is not apparent until after equipment is unpacked, a
request for inspection of concealed damage must be made with carrier within

retain all contents plus external and internal packaging materials for inspection. The carrier will make

an inspection and will supply necessary claim forms.

INSTALLATION

Each machine has been properly wired and inspected at the factory for operation on the voltage and

type of current specied on the nameplate. Machines with a nameplate stamped 120V, are equipped

for operation on 120 volt 60 hertz AC single phase service and must be connected to a separate 15
amp circuit with a 3 wire grounded, polarized receptacle. 230V models must be connected to a 230V,
60Hz, AC single phase service.

Water hardness in some areas will cause scaling (lime scale buildup) in your equipment. This scaling
will coat the inside of the reservoir and waterlines of your Hot Food Humidity Cabinet. Therefore,
STAR Manufacturing recommends using distilled water for the prevention of scaling in your
equipment. This will prolong the life of your STAR equipment.

15 days. Be certain to

WARNING

CAUTION

DO NOT CONNECT TO ANY OTHER TYPE OF
CURRENT SOURCE OR THE MACHINE WILL BE
SERIOUSLY DAMAGED.

The guarantee of this machine covered by the warranty

card does not apply if an improper installation has been
made.

DO NOT BLOCK VENT HOLES ON TOP OF THE
CABINET.

Fill Light - This is used as a reminder during start

up. When the power switch is pushed on the

ll light will illuminate to remind the operator to
ll the reservoir. The ll light will go OFF when
the reservoir is lled to the maximum.

Temperature and Humidity Control Operation -

a. Fahrenheit or Celsius Selection - The control will read cabinet air temperature in F° or C°. To

change this indication press and hold the MODE switch and then press + to change the setting.

b. Pre-set Selection - This control comes from the factory with 6 programmed pre-set

selections indicated as Preset 1, etc. These

correspond to the temperature and humidity
setting as indicated in the table below:

Cabinet Air

Preset No. Temp. Setting Humidity Setting

1 175F° 10

2 120F° 10

3 170F° 6

GENERAL OPERATING INSTRUCTIONS

1. Install inside food rack or pizza/pretzel shelves depending on the model

unit purcha s e d . Th e s h e lves are i n t h e e n c l osed accessory ca r t on

(See Figure 1).

2.

Plug the unit into a grounded 120 V.A.C. receptacle (230V receptacle for European

models).

LOCATION AND FUNCTION OF CONTROLS

The operating controls are located above the door on the side of the unit next to the water ll (See
Figure 2).

1. Temperature Indicator - Displays temperature

2. Water Level Indicators - When ON water level is too low

3. ON/OFF Switch - Activates lights, digital thermometer and air circulation system.

4. Low Water Light - When the light is ON this indicates that water must be added. The ll light will
also come on. Element shuts OFF until water is added.

4 175F° 6
5 150F° 5
6 150F° 5

To select Pre-Sets press and hold MODE then press SELECT to toggle through pre-sets. Stop on

the desired pre-set setting. For specic food products, see the Recommended Control Settings and
Holding Times section.

Temperature and Humidity Programming- A pre-set can be changed. Hold + and - for 3 seconds until

the current temperature is displayed. Push + up or - down to set the desired cabinet temperature.
Press MODE to display the humidity setting. Press + up or - down to set the desired humidity level.
A setting of 5 will be about 25% relative humidity. Press MODE to leave program.

By pressing and holding MODE and then SELECT different pre-sets can be individually

chosen and reset to a specic temperature and humidity setting.

(Maximum temperature is 175°F and humidity 10).

NOTE

Using tap water will promote scaling that will eventually
cause clogging of water tubes and prevent the proper
operation of the Humidity Cabinet. The use of distilled
water will prevent scaling inside the water lines of the
cabinet.

5. Fill reservoir by lifting reservoir lid and pouring water in until both the ll and low water light
should be "OFF" when the tank is full. HFD-2A holds approximately 3 quarts and HFD-3A holds
approximately 5 quarts. Both lights will be off until the water level drops below a specied set

level and the low water light comes on. The water heater will stop operating until water is added.

The ll light will be "ON" until the water level reaches the ll water indicator probe. 5
quarts. Both lights will be off until the water level drops below a specied set level and

the low water light comes on. The water heater will stop operating until water is added.

The ll light will be "ON" until the water level reaches the ll water indicator probe.

OPERATING PROCEDURES

1. Turn power switch on.

2. Set desired temperature and humidity or desired pre-set. Allow approximately 20 minutes

for machine to reach proper temperature. (Time will vary depending on temperature

setting.)

Fill water reservoir.

3.

4. Monitor cabinet temperature via the digital thermometer on the control (See Figure 2).

5. Periodically monitor water level by indicator on control panel (See Figure 2).
