Thank you for purchasing the single cup RC400 brewer. This brewer is a digitally controlled commercial/residential
coffee brewer that brews one cup at a time. The brewer is designed for optimal use with RealCup™ capsules and
is compatible with Keurig®* K-Cup®* capsules.
The Single Cup brewer can be plumbed into a potable water supply. If a water line is not available, the brewer
can be used as a pour over brewer. The brewer requires a dedicated 15 amp, 120V, 60 Hz power source. If the
brewer is plumbed, it will refill the reservoir automatically. If used as a pour over brewer, the user must manually
refill the reservoir as necessary.
The operating principle of this machine is that a user places a coffee mug on the drip tray (or foldaway tray), then
places a new RealCup™ capsule in the brew chamber. The user then closes the chamber and selects, from the user
interface screen, their beverage and size choice. Once these selections are made, the BREW button is pressed. The
brewer is designed to dispense 4 (118), 6 (177), 8 (237), 10 (296), 12 (355), and 16 (473) fluid ounces (ml). Actual
dispensed volume is approximately 10% less to allow for addition of milk, cream, or sweetener if desired.
*RealCupTM brand has no affiliation with K-Cup®or Keurig Inc. Keurig®and K-Cup®are registered trademarks of Keurig Inc.

the brewer. Do not disassemble the brewer.
DANGER
For indoor use only. Do not install or use outdoors, in moving equipment, or watercraft.
Use the product for its intended purpose only. Any other usage is inappropriate and may be dangerous. The
manufacturer assumes no responsibility for injury, loss, or damage resulting from improper machine use.
Brew probes are sharp. To prevent injury, do not place fingers inside the brew chamber.
Risk of burns. The brewer uses 185°F- 200°F water that, if not properly handled, could cause burns. Do not permit
children to use this appliance unless there is direct adult supervision. Keep away from pets and other animals.
To avoid the risk of burns, do not operate without bezel installed.
Allow brewer to cool before cleaning or maintaining.
Hot surfaces may cause burns. Do not touch the brewer while in operation.
To prevent scalding by hot water, do not open brew chamber while brewing.
To prevent scalding by hot water, do not move or tilt the brewer. Moving or tilting the brewer could result in
water spilling from the reservoir. Internal boiling is possible at high elevations. You must reduce temperature
set point below boiling point for your elevation.
To avoid scalding, use appropriate cup rest to minimize splash. Allow a minimum of 1/2” clearance between cup
rim and brewer dispense spout to prevent spills when removing a full cup. Center cup with dispense spout while
brewing and allow brewer cycle to complete before opening brew chamber or removing cup.
To avoid pinching, keep fingers clear of brew chamber when closing.
CAUTION
For best results, remove used Real Cup™ capsule from brew chamber after each brew is complete.
Avoid spills by not removing the reservoir while Auto-Fill unit is filling; allow filling to complete before removing
reservoir.
A qualified professional should perform installation, maintenance and repairs.
Installation, maintenance or repairs by unqualified personnel may damage the brewer and void the
manufacturer’s warranty.

General Information
This operating manual includes instructions for using
and maintaining your coffee brewer; keep this manual
readily available.
After unpacking your brewer, check to ensure that your
machine has not been damaged during shipping and
includes all components. Notify your service
representative regarding any questions or concerns
before installing.
During various stages of operation, you may hear
normal operating sounds that are unfamiliar. The
following noises are normal:
Buzzing/Clicking - Heard when the water pump
energizes and/or the three way valve opens and
closes to dispense water or direct water to reservoir.
Popping – A damaged RealCup™ capsule could
result in a popping sound.
Pulsating/Whirring – Under normal operating
conditions, an internal air pump activates at the end
of a brewing cycle and you will hear it while
energized.
Water running or gurgling – On a pour over
installation, you will hear gurgling when reservoir
is empty before the end of a brew cycle. On an auto
fill installation, you will hear this sound as the
brewer automatically refills.
Do not use a damaged RealCup™ capsule or re-insert a
capsule that has been previously inserted & removed.
This may result in coffee grounds and unwanted
material inside the brew chamber and the drinking cup
or mug. Damage to RealCup™ capsule can include but
is not limited to damage around the edge of the foil
seal or denting and deformation of the RealCup™
capsule.
To ensure food safety and proper operation, clean
machine regularly following the daily and weekly
cleaning instructions. Cleaning and water evacuation
instructions are found in the Cleaning and
Maintenance section of this manual.
When turning off the machine for an extended period,
be sure to evacuate the water inside the brewer
completely. Otherwise, the water inside the machine
could freeze and lead to damage or cause mold to
appear.
Water pipe connections and fixtures directly connected
to a potable water supply shall be sized, installed, and
maintained in accordance with federal, state, and local
codes. This product requires an approved back flow
prevention device, such as a double check valve, to be
installed between the machine and the water supply.
To prevent foreign material from entering the brewer,
keep brew chamber and reservoir lid closed.
To ensure proper operation of the electronic controls,
do not use reverse osmosis, distilled, or de-ionized
water.
The RC400 brewer hot water temperature is factory set
at 195°F (90.6°C). If your brewer is operated above 4000
feet in elevation, set point adjustment may become
necessary. If the brewer reservoir fogs or experiences
hot water dripping into the reservoir, this indicates the
set point must be lowered. In addition, if the set point
is too high, you could experience less than expected
brew volumes.

Cleaning & Maintenance
Cleaning Instructions
Daily cleaning:
To ensure food safety and proper•
operation, empty the drip tray as needed and
wash in a solution of dish detergent and water,
rinse thoroughly.
All external surfaces can be cleaned with a soft,•
damp cloth. Do not use any abrasives. They will
scratch the external surfaces.
Do not place brewer or individual parts into a•
dishwasher.
Weekly cleaning:
Remove and empty the reservoir tank and wash in•
a solution of dish detergent and water, rinse
thoroughly.
Ensure surrounding surfaces and under the brewer•
are cleaned regularly to prevent the attraction of
vermin and bacteria growth from spilled coffee
and sugars.
Draining:
This action will clear water from the brewer. Do not
place brewer or individual parts into a dishwasher.
1. Power off brewer. Allow brewer to cool. Close water
supply valve (Auto-Fill only) and disconnect water
line.
2. Remove and empty reservoir.
3. Remove back panel, uncap drain line and drain tank.
Recap and replace back panel.
4. Turn on brewer.
5. Place a cup under the brew chamber, hold down
reservoir detection switch and start a brew
sequence.

Descaling: This action will help remove hard water
deposits. Process will take approximately 3.5
hours and requires 72 oz. of distilled vinegar. Do not
place brewer or individual parts into a dishwasher.
The frequency of descaling depends on the level of
mineral content of your water. This is why we
recommend using filtered or bottled water. Calcium
deposits or scale may build up in your brewer and
hinder your brewer performance. Regularly descaling
your brewer every 3 to 6 months helps prevent this
from occurring; however, if you feel that your water
has a higher level of mineral content, then you should
consider descaling more often.
If the action screen has a
red exclamation mark, call
service provider. If it is
yellow, user action is
required.

Gracias por adquirir el infusor para una sola taza RC400. Esta máquina es un infusor comercial/residencial con
control digital, que permite preparar una taza a la vez. El infusor está diseñado para que se utilice de manera
óptima con las cápsulas RealCup™ y es compatible con las cápsulas Keurig®* K-Cup®*.
El infusor para una sola taza se puede instalar de manera fija a un suministro de agua potable. Si no hay un
sistema de suministro de agua disponible, el infusor puede utilizarse como infusor para verter por encima. El
infusor requiere una fuente de energía exclusiva de 15A, 120V y 60Hz. Si el infusor está instalado de manera
fija, se llenará el depósito automáticamente. Si se utiliza como infusor para verter por encima, el usuario debe
volver a llenar el depósito manualmente según sea necesario.
El principio de funcionamiento de esta máquina es el siguiente: el usuario coloca una taza para café en la bandeja
escurridora (o plegable) y, luego, introduce una cápsula RealCup™ nueva en la cámara de infusión. A continuación,
el usuario cierra la cámara y selecciona su bebida y el tamaño que desea en la pantalla de la interfaz del usuario.
Después de realizar estas selecciones, pulsa el botón de infusión. El infusor está diseñado para dispensar 4, 6, 8,
10, 12 y 16 onzas líquidas (118, 177, 237, 296, 355 y 473 ml). El volumen que realmente se dispensa es
aproximadamente un 10% menor para permitir el agregado de leche, crema o endulzante, si se desea.
*La marca RealCup™ no tiene afiliación alguna con K-Cup® o Keurig Inc. Keurig® y K-Cup® son marcas comerciales registradas de Keurig
Inc.

Precauciones de seguridad (continuación)
Para evitar posibles casos de electrocución, quemaduras u otras lesiones e impedir que el infusor se dañe, no lo
sumerja en agua ni en líquidos de limpieza.
No opere un infusor averiado. Controle el cable de alimentación y el suministro de agua con frecuencia. Si el
cable o el enchufe están dañados o desgastados, no utilice el infusor. Apague el suministro de agua y desconecte
la energía eléctrica.
Apague y desenchufe el infusor antes de la limpieza o el mantenimiento.
Riesgo de asfixia. El embalaje del producto contiene una bolsa de plástico. Mantenga las bolsas de plástico fuera
del alcance de los niños.
Si la máquina funciona de manera anormal, desconecte la energía eléctrica y notifique al personal de
mantenimiento calificado para que realice las reparaciones pertinentes. No permita que personal de
mantenimiento no calificado intente hacer reparaciones. El infusor no contiene componentes que el usuario
pueda reparar. No lo desmonte.
PELIGRO
El infusor es solo apto para uso en interiores. No lo instale ni lo utilice al aire libre, en equipos en movimiento
ni en embarcaciones.
Utilice el producto únicamente para los fines previstos. Cualquier otro uso es inadecuado y puede ser peligroso.
El fabricante no asume ninguna responsabilidad por lesiones, pérdidas o daños que se produzcan a partir del
uso incorrecto de la máquina.
Las sondas de infusión son filosas. Para evitar lesiones, no coloque los dedos en el interior de la cámara de
infusión.
Riesgo de quemaduras. El infusor utiliza agua a una temperatura de 185°F a 200°F, por lo que, si no se opera
de manera adecuada, podría provocar quemaduras. No permita que los niños usen este aparato, a menos que
estén bajo la supervisión directa de un adulto. Manténgalo fuera del alcance de mascotas y otros animales.
Para evitar el riesgo de quemaduras, no opere el infusor sin el bisel instalado.
Antes de la limpieza o el mantenimiento, deje enfriar el infusor.
Las superficies calientes pueden provocar quemaduras. No toque el infusor mientras esté en funcionamiento.
Para evitar quemaduras con agua caliente, no abra la cámara de infusión durante la preparación.
Para evitar quemaduras con agua caliente, no mueva ni incline el infusor. Mover o inclinar el infusor podría
ocasionar que se derrame agua del depósito. Es posible que se produzca ebullición interna a altitudes elevadas.
Debe disminuir el punto de ajuste de temperatura por debajo del punto de ebullición según la altitud a la que
se encuentre.
Para minimizar las salpicaduras y evitar quemaduras, utilice el apoyo adecuado. Para evitar derrames cuando
retire una taza llena, deje un espacio de ½” como mínimo entre el borde de la taza y la boquilla vertedora del
infusor. Durante la preparación, coloque la taza en el centro, debajo de la boquilla vertedora, y deje que finalice
el ciclo del infusor antes de abrir la cámara de infusión o de retirar la taza.
Mantenga los dedos alejados de la cámara de infusión cuando la cierre, para evitar pellizcos.

Información general
Este manual de uso incluye instrucciones para utilizar y
realizar el mantenimiento del infusor. Guarde este
manual a mano.
Después de desembalar el infusor, compruebe que no
haya sufrido daños durante el envío y que incluya todos
los componentes. Si tiene alguna pregunta o inquietud
antes de instalar el infusor, notifique al representante
de servicio al cliente.
Tenga en cuenta que el material de embalaje puede ser
peligroso. Manténgalo fuera del alcance de los niños y
deséchelo de inmediato.
Durante varias de las etapas de uso, es posible que oiga
sonidos normales del funcionamiento que no le resulten
familiares. Los siguientes sonidos son normales:
Zumbido/chasquido: Se produce cuando se activa la
bomba de agua o cuando la válvula de tres vías se
abre y se cierra para dispensar agua o para enviar
agua al depósito.
Estallido: Cuando se daña una cápsula RealCup™,
esto podría generar un sonido de estallido.
Pulsación/silbido: En condiciones normales de
funcionamiento, se produce este sonido cuando se
activa una bomba de aire interna al final de un ciclo
de preparación.
Flujo de agua/gorgoteo: En una instalación para
verter por encima, se puede oír un gorgoteo
cuando el depósito está vacío antes del final de un
ciclo de preparación. En una instalación de llenado
automático, se puede oír este sonido cuando se
llena el infusor automáticamente.
No utilice una cápsula RealCup™ dañada, ni vuelva a
introducir una cápsula que se haya introducido y
retirado anteriormente. Esto puede producir que
queden granos de café y materiales no deseados en el
interior de la cámara de infusión y en la taza o jarra. Los
daños en la cápsula RealCup™ pueden ser averías
alrededor del borde de la tapa de papel aluminio o
abolladuras y deformaciones en la cápsula RealCup™,
entre otros.
Para garantizar la seguridad de los alimentos y un
funcionamiento adecuado, limpie la máquina de
manera regular, de acuerdo con las instrucciones de
limpieza diaria y semanal. Las instrucciones de limpieza
y evacuación del agua se encuentran en la sección
“Limpieza y mantenimiento” de este manual.
Cuando apague la máquina durante un período
prolongado, asegúrese de vaciar el agua del interior de
los tubos por completo. De lo contrario, el agua que
quede en el interior de la máquina podría congelarse y
provocar daños o la aparición de moho.
Los accesorios y las conexiones de la tubería de agua
que estén conectados directamente a un suministro de
agua potable deben ser del tamaño indicado en los
códigos federales, estatales y locales, y deben instalarse
y mantenerse de acuerdo con ellos. Este producto
requiere que se instale un dispositivo antirretorno
aprobado, como una válvula de retención doble, entre
la máquina y el suministro de agua.
Para evitar que ingresen materiales extraños en el
infusor, mantenga cerradas las tapas de la cámara de
infusión y del depósito.
Para garantizar el funcionamiento adecuado de los
controles electrónicos, no utilice agua de ósmosis
inversa, destilada o desionizada.La configuración de
fábrica de la temperatura del agua caliente del infusor
RC400 es de 195°F (90.6°C). Si se utiliza el infusor a más
de 4000pies de altitud, es posible que sea necesario
modificar el punto de ajuste. Si el depósito del infusor
se empaña o si gotea agua caliente en el depósito, esto
indica que se debe bajar el punto de ajuste. Además, si
el punto de ajuste es demasiado elevado, podría
obtener volúmenes de infusión menores de los
esperados.
Para obtener mejores resultados, retire la cápsula RealCup™ usada de la cámara de infusión después de finalizar
cada preparación.
Para evitar derrames, no retire el depósito mientras se esté llenando la unidad de llenado automático. Deje
finalizar el llenado antes de extraer el depósito.
Solo un profesional calificado debe realizar la instalación, el mantenimiento y las reparaciones.
La instalación, el mantenimiento o las reparaciones por parte de personal no calificado pueden dañar el infusor
y anular la garantía del fabricante.
Este equipo debe instalarse de acuerdo con los códigos nacionales y locales correspondientes que rijan en el
país o en la región donde se instale el aparato.
Comuníquese con el fabricante para informar cualquier mal funcionamiento o avería del infusor.
Cuando apague la máquina durante un período prolongado, asegúrese de retirar el agua del interior del infusor
por completo; de lo contrario, el agua podría congelarse dentro de la máquina y provocar daños o la aparición
de moho.
Para reducir el ingreso de materiales extraños en el infusor, mantenga cerradas las tapas de la cámara de infusión
y del depósito.
Para evitar que la taza se desborde accidentalmente, pulse el botón de infusión para detener la preparación.
