NOTICE: This term refers to information that needs special attention or must be fully understood.
DANGER
To prevent the possibility of electrocution, burns, or other injuries and to prevent damage to your brewer, do not
immerse in water or any cleaning liquids.
Do not operate a damaged brewer. Inspect the power supply cord and water supply often. If cord or plug is damaged or worn, do not use your brewer. Turn off the water supply and disconnect the electrical power.
Turn off and unplug the brewer before cleaning or maintenance.

permit non-qualified service personnel to attempt repairs. No user serviceable components inside the brewer.
Do not disassemble the brewer.
WARNING
Brew probes are sharp. To prevent injury, do not place fingers inside the brew chamber.
The brewer must only be connected to a three wire 120 VAC, 60 Hz, 15 Amp, electrical circuit.
Allow brewer to cool before cleaning or maintaining.
CAUTION
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.
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.

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 sp out 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.

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.
Please note that packaging material can be dangerous. Keep away from children. Discard promptly.
During various stages of operation, you may hear normal operating sounds that are unfamiliar. The following noi ses
are normal:
Buzzing/Clicking - Heard when the water pump energizes and/or the three way valve opens and closes to dis-
pense water or direct water to reservoir.
Popping – A damaged Real Cup™ 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.
ENGLISH

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 Real Cup™ capsule or re-insert a capsule that has be en previously been inserted & re-
moved. This may result in coffee grounds and unwanted material inside the brew chamber and the drinki ng cup or
mug. Damage to Real Cup™ capsule may be around the edge of the foil seal or denting and deforming the entire
Real Cup™ 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 piping completely.
Otherwise, the water inside the machine could freeze and lead to damage or cause mold to appea r.
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 cl osed.
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
o
F (90.6o C). If you 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.

Product Description
Thank you for purchasing the RealCup™ 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 itself automatically. If used as a pour over brewer, 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 fresh RealCup™ capsule in the brew chamber. The user then closes the chamber and selects, from the
