Safety Precautions

Important Safety Information

This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.

For your safety and the safety of others, read all warnings and the operator’s manual before installing or using the product.

DANGER: This term warns of imminent hazard that will result in serious injury or death.

WARNING: This term refers to a potential hazard or unsafe practice, which could result in serious injury. CAUTION: This term refers to a potential hazard or unsafe practice, which could result in minor or moderate injury or property damage.

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.

Risk of suffocation. The product packaging contains a plastic bag. Keep plastic bags away from children.

Disconnect power if the machine functions abnormally and notify qualified service personnel for repairs. Do not 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.

To avoid the risk of burns, do not operate without bezel installed.

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.

NOTICE

For best results, remove used Real Cup™ capsule from brew chamber when brewing is complete.

Avoid spills by not removing the reservoir while Auto-Fill unit is filling; allow complete filling cycle 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.

This equipment must be installed in accordance with the appropriate national and local codes of the country and/ or region in which the appliance is installed.

Contact the manufacturer to report any malfunction of or damage to the brewer.

When turning the machine off 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 appear.

To reduce foreign material from entering the brewer, keep brew chamber and reservoir lids closed. To prevent accidental over filling of cup, press “BREW” to stop.

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 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 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	3

4

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 been previously been inserted & removed. This may result in coffee grounds and unwanted material inside the brew chamber and the drinking 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 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 195o 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

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.

Unpacking Your Brewer

1.Place carton on a table or a stable, firm surface.

2.Open the box. Do not use sharp objects to open the box. Doing so could cause damage to the brewer.
