INSTALLATION
SET UP
1. Carefully remove any packing material from the
induction charger and check loose packing
material for small parts or accessories. Inspect
the charger for concealed damage before placing
packing material aside. Keep the packaging until
you are confident with the equipment’s
performance.
2. The Smart▪Therm®Charger must be installed on
top of a flat, level countertop or shelving. Be
careful to maintain at least two inches of

clearance on all sides of the charger for cooling.
Do not place over paper or loose material that
may inhibit air flow into the bottom air intakes.
Consider the Dinex®Induction Stand (Accessory
product) DXPICTABLEM (Mobile with casters)
DXPICTABLE (Not mobile).
3. The Smart▪Therm®induction charger isequipped
with a locking plug. This plug is part of a system
that will protect you from injury in the event of an
electrical malfunction inside the unit. Be sure the
plug is fully plugged into a matching socket that is
properly grounded.
! ATTENTION: DO NOT cut or break off the larger
angled prong on this plugor change the plug or power
in any way. Doing so will create a safety hazard and
will also void the warranty.
4. CONFIRM THAT INCOMING VOLTAGE
MATCHES THE CHARGER. The charger must
be plugged into a grounded 208V 1-phase, 20A
dedicated NEMA L6-20R receptacle. A dedicated
electrical outlet is required for EACH
Smart▪Therm®® charger. Make sure that your
Smart▪Therm®Charger is plugged into an
energized circuit.
! CAUTION: A product identification label on the
bottom of the unit specifies the operating voltage,
current, frequency, phase, and maximum wattage of
the charger. Plugging or wiring the charger into less
voltage than the charger is rated may significantly
decrease the performance of the unit or damage
internal electrical components.
! IMPORTANT: Each charger should be connected
to its own dedicated circuit. They should not be
connected to circuits sharing compressors or other
heavy current draw devices (i.e., plate heaters, steam
tables, etc.)
5. Do not use any Smart▪Therm®charger that has
a damaged cord orplug.Consult the warrantyand
follow the instructions for service.
6. Do not move the Smart▪Therm®Charger when it
is electrically connected.
7. Do not place foreign objects on the charger, or
between the Dinex®base and the charger
surface. Foreign objects may heat within the
induction field and cause damage to the charger
surface and/or base.
8. A grease filter is mounted to the bottom of the
unit. Assure the filter is seated and free of
excessive debris or grease. For replacement
filters order DXPLE9560.
9. Do not let the power cord touch hot surfaces.
10.The center of the charger may get hot to the touch
after hours of continuous use. Use caution when
loading and unloading bases.
11.The charger requires ample air flow to cool the
internal electronic components. Air is pulled in
from the bottom of the unit from the front and
sides, and exhausted towards the rear of the unit.
Assure that nothing obstructs the airflow about all
four sides of the unit. Allow at least two inches
from a wall or partition.
! ATTENTION: Do not attempt to open the charger
or perform service of any kind. This product can only
be serviced by a Dinex®Authorized Service Agent or
designated Dinex®personnel. Contact Dinex®at 1-
888-673-4639 for service information.
! IMPORTANT: Any installation not matching the
requirements discussed in this manual will
automatically void the product’s warranty.
! IMPORTANT: Every installation site has different
electrical wiring requirements. Because many
different local codes exist, it is the owner and
installer’s responsibility to comply with all federal,
state, and local codes. Dinex®is not responsible for
any consequential damages, either expressed or
implied, because of failure to comply with installation

bottom of the screen will continue to fill in to show
the progression of charge. If the base is removed
prior to the status bar being completely filled the
base will not be fully charged and may result in a
lower delivery temperature.
! IMPORTANT: You will hear three loud “BEEPS” if
you remove the base before it is fully charged.
4. Your Smart▪Therm®charger and Smart Base

after placing a base on the charger, remove the
base and reposition –assuring the base is seated
flat to the top, and within the positioning rails.
6. The status bar tracks the progress of the base
charge. After the status bar is completely filled the
charger will display “Base Ready” and will beep
indicating that base is at full temperature. Charge
time for a base will be between 16 to 20 seconds.
Note: Low incoming voltage may increase charge
time.
! IMPORTANT: Fluctuations in voltage may affect
heating time.
7. If the charger sees no activity for an extended
period, it will beep 2 times and go into “Sleep”
mode to conserve power. This will be indicated by
the display reading “Power Save. Press any
button to return to previous mode”. Press any
button to exit “Sleep” mode.
