A COMMITMENT TO SAFETY

The SandenVendo is committed to safety in every aspect of our product design.

SandenVendo is committed to alerting every user to the possible dangers involved in improper

handling or maintenance of our equipment. The servicing of any electrical or mechanical

device involves potential hazards, both to those servicing the equipment and to users of the

equipment. These hazards can arise because of improper maintenance techniques. The

purpose of this manual is to alert everyone servicing SandenVendo equipment of potentially

hazardous areas, and to provide basic safety guidelines for proper maintenance.

This manual contains various warnings that should be carefully read to minimize the risk of

personal injury to service personnel. This manual also contains service information to insure

that proper methods are followed to avoid damaging the Hot Food Display (HFD) or making it

unsafe. It is also important to understand these warnings are not exhaustive. SandenVendo

could not possibly know, evaluate, or advise of all of the conceivable ways in which service

might be done, nor can SandenVendo predict all of the possible hazardous results. The

safety precautions outlined in this manual provide the basis for an effective safety program.

Use these precautions, along with the service manual, when installing or servicing the HFD.

We strongly recommend a similar commitment to safety by every servicing organization. Only

properly trained personnel should have access to the interior of the machine. This will

minimize the potential hazards that are inherent in electrical and mechanical devices.

SandenVendo has no control over the machine once it leaves the premises. It is the owner or

lessor’s responsibility to maintain the Hot Food Display in a safe condition. Follow all Safety

Rules and Safety Warnings in this manual. If you have any questions, please contact the

Technical Services Department of SandenVendo.

SAFETY RULES

•Read the Safety Warnings before installation or service.

•Test for proper grounding before installing to reduce the risk of electrical shock and fire.

•Turn off power switch and disconnect power cord from wall outlet before servicing.

•Use only fully-trained service technicians for Power-On servicing.

•Use adequate equipment when moving the HFD.

•Use only authorized replacement parts.

•Be aware of inherent dangers in rocking or tipping the HFD.

•Always turn power off before plugging or unplugging HFD to wall outlet.

FOOD FOR THE HOT FOOD DISPLAY

The HFD, HFDM, and HFDH units are design to hold unwrapped, wrapped, and boxed

food. The HFDHC is designed to hold wrapped and boxed food. Hot food displays

are not designed to heat cold food - put only hot food in the hot food display.

SAFETY WARNINGS

The HFD is for indoor use only. Do not use near water or in condensing humidity.

To prevent electric shock or fire, do not kink, pull, or pinch the power cord, and insure no

equipment is resting on the power cord. If the power cord is damaged, unplug and replace.

Do not connect with other plugs. Do not use an extension cord.

When unplugging, first turn off the power switch. Then pull the plug at the end of the power

cord, not by pulling the power cord, since the cord can be damaged, overheat, and cause a

fire.

Do not spray water on the HFD. It may cause an electric shock or fire.

Do not touch the power plug, switches, or other electrical parts with wet hands. It can cause

an electric shock.

Periodically check that the plug is pushed in all the way.

To prevent injuries due to falling objects, liquid spills, electric shock or fire, do not place heavy

objects or liquid-filled objects on top of the HFD.

To prevent electric shock or fire, do not use volatile or flammable products in or near the HFD.

When moving the HFD: turn the HFD off, unplug, and allow the unit to cool. To prevent glass

breakage and injury, do not push on the glass. Also, use proper equipment and lifting

techniques. Insure the product doesn’t tip while it is being moved.

If a lamp or any glass cracks or breaks, turn off the power and discard all food in the HFD.

Replace lamp and / or glass. Remove all glass fragments. Carefully inspect all surfaces,

corners, and gaskets to insure all glass fragments have been removed before returning HFD

to service.

Keep HFD out of direct sunlight and away from heat sources.

Do not hang from the door –this may cause injury or electric shock.

Turn off and unplug HFD before servicing, and let HFD cool before cleaning or servicing.

Use proper tools while servicing.

Use only authorized replacement parts.

The HFD temperatures are factory set to meet NSF food safety requirements. Changing

temperature settings may adversely impact food safety.

The lamps are an integral part of the food heating system. If a lamp is not illuminated, the

temperatures may not be maintained for food safety.

OPERATION

Display and Keypad

Timer Setting and Operation

Note: to help prevent keypad damage, push keypad buttons only with finger or thumb; do not use

fingernail, utensil, tool, pen, or other object.

Circulation fans may be turned on or off by the switch at the top rear of the HFD (HFD 7 and HFDC).

Normal Operation

Pressing the I/O button turns the HFD on or off. When controller is off, all lamps, heaters, displays

and indicators are off. Front on/off button (HFDC only): press and hold for 5 seconds to turn the

HFDC on or off.

Timers

Holding down the TIME button, then pressing a Timer button, turns off the timer. When a timer is off,

pressing the Timer button once sets the countdown timer to the value preprogrammed into the

controller.

Pressing the Timer button again within three seconds (while the indicator next to the button is

blinking) sets the timer to 30 minutes.

Each successive press (within three seconds) adds 30 minutes to the time, up to 4 hours.

At 4 hours, the next button press cycles the timer back to 30 minutes again.

Once the timer is activated, the LED next to the shelf timer button stops blinking and stays on.

The display then reverts to HFD internal air temperature.

While a timer is on, pressing a timer button displays the remaining time for 4 seconds, then shelf

actual temperature (not the setpoint) for 4 seconds, and then the display reverts to the internal

ambient temperature display.

At 15 minutes remaining time, the LED turns yellow.

When no time remains, the LED turns red, plus an audible alarm sounds. Shelf heaters stay on.

Pressing the timer button next to the blinking red LED clears the alarm and restarts the timer.

Converting Temperature from °F to °C (or °C to °F)

With controller power off, hold down the TIME button, then press and hold the I/O button until the

display comes on. The display shows the firmware revision (example 4.11).

Press and release the TIME button to change from °F to °C (or °C to °F).

Push the I/O button to turn on the HFD and lock in this setting.

To turn the ambient temperature display on or off: with the controller on, press and hold the Time

button and press the I/O button. (This feature is disabled in firmware revision 4.01).

Front Door

If the front door is opened (HFD6 and 7 only), the controller turns off only the lights. The display

reads "OPEn". After closing the front door, the lights turn on, and the display reverts to internal

ambient temperature.

Heater Temperature Adjustment

Push the I/O button to turn the unit off. The lights and heaters turn off.

With controller power off, hold down the TIME button, then press and hold the I/O button until the

display comes on. The display will show the firmware revision.

Push either of the two buttons corresponding to the shelf that you wish to change the temperature.

Both lights on either side of the buttons will begin blinking.

Push and hold the button on the left to decrease the temperature (shown on the display).

Push and hold the button on the right to increase the temperature (shown on the display).

Repeat the procedure using the buttons that correspond to each of the six shelves (for HFD6 & 7), or

four shelves (HFDM).

Once the temperatures are adjusted for each of the separate zones, push the I/O button to lock in

the new temperature settings and to turn the HFD back on (the lights in the HFD will come on).
