IMPORTANT SAFEGUARDS

When using electrical appliances, basic safety precautions should always be followed to prevent the risk of fire, electric shock, burns, or other injuries and damage.

READ ALL OPERATING AND SAFETY INSTRUCTIONS CAREFULLY.

• Do not touch hot surfaces. The top of the unit will get hot when brewing. Use the side arms of the machine to move the unit.
• To protect against fire, electrical shock, and injury, do not immerse the cord, plug, or appliance in liquid.
• Unplug from the outlet when not in use, and before cleaning. Allow it to cool before putting on or taking off parts and before cleaning the appliance.
• The machine must be turned off before unplugging from the outlet.
• The voltage in your home should correspond to the voltage indicated on the bottom of your appliance.
• Close supervision is necessary when any appliance is used by or near children.
• Do not operate the appliance with a damaged cord or plug.
• Do not operate the appliance after appliance malfunctions, or has been dropped or damaged in any manner.
• If the unit is damaged or dropped, return it to Ratio for service.
• The use of accessory attachments not recommended by Ratio may result in fire, electric shock or injury.
• Do not use outdoors or in a damp area. Do not place the appliance on a hot surface.
• Do not let the cord hang over the edge of a table or counter, or touch hot surfaces.
• Do not place on or near a hot gas burner, electric burner, or in a heated oven.
• To disconnect the appliance, remove the plug from the electrical wall outlet. When the carafe is removed from the base of the unit, the heating element cannot be turned on.
• Do not use this appliance for anything other than its intended use.
• Place the appliance on a level surface.
• Do not operate the appliance without water.
• Do not use hot water. Only fresh, cold water should be used to fill the water tank.
• Do not use a cracked carafe or a carafe with a loose or weakened handle.
• Do not clean any part of the machine or carafe with harsh detergents, steel wool pads, or other abrasive materials.
• Do not place the carafe in the dishwasher. Hand wash only.
• The carafe is designed for use with this appliance. It must never be used on a range or stove top.
• Do not hit the showerhead with the carafe, as it may damage the carafe.
• A short power supply cord is provided to reduce the risk resulting from becoming entangled in or tripping over a longer cord.
• Extension cords are available and may be used if care is exercised in their use.
• If an extension cord is used, (1) the marked electrical rating of the extension cord should be at least as great as the electrical rating of the appliance, and (2) the longer cord should be arranged so that it will not drape over the counter or table top where it could be pulled on by children or tripped over unintentionally.

DETAILED INSTRUCTIONS

• Fill the tank.
  Fill to the desired level with fresh, cool water. If using the Ratio carafe to transfer water, ensure it is free of coffee residue from previous brews.
• Choose your filter.
  The Ratio carafe was designed to use Chemex paper filters or our custom perforated stainless steel filter, the Ratio Kone.
• Add coffee grounds.
  Add freshly ground coffee to the filter. We recommend starting with 14 level tablespoons, or 70 grams, for a full batch. For a half batch, add 7 level tablespoons, or 35 grams. When placing the carafe back in the Ratio Eight, make sure you tilt the carafe so that you do not hit the showerhead.
• Begin the brewing cycle by pushing the start button.
  You can preheat the carafe with hot water from your sink, a kettle, or by running a brew cycle of any size without coffee. Alternatively, you can fill the tank beyond your intended batch size and stop the brew cycle when the tank reaches the desired level by touching the button. If you run more than intended, just top off the tank as needed.Suggested brew ratios of water to ground coffee

THE BREWING PHASES

• Bloom
  The Ratio Eight will deliver a small amount of water to pre-saturate the grounds in preparation for the full brewing cycle. The water distributed then allows the fresh-roasted coffee to breathe, and the coffee will begin to “Bloom.” The coffee will bubble slightly, signaling it is ready for the next phase.
• Brew
  After a few moments, the Ratio Eight will switch from “Bloom” to “Brew”, and the hot water will again be delivered from the shower head. Depending on the amount of water you add to the tank, the brewing time will take between 4 and 7 minutes, including bloom rest period and final draining of coffee grounds. The Ratio Eight optimizes the amount of “Bloom” and “Brew” time, while the powerful heating element will keep the water temperature between 195ºF/90ºC and 205ºF/96ºC. If the tank is empty, the heating element will turn off.
• Ready
  Your brew cycle will complete when the “Ready” indicator is on. The water may continue to drip through the grounds for the next 10-40 second,s depending on the grind.

Remove the carafe from the base of the unit, and then remove the filter with the spent coffee grounds inside. The Ratio Eight will turn itself off automatically after the carafe has been removed. If you do not remove the carafe the “Ready” light will blink for 20 minutes. You can discard or compost the coffee grounds.

CLEANING

To keep the Ratio Eight looking and performing its best, we recommend a regular routine of cleaning the machine with the Ratio Machine Wash. This is an all-natural detergent and descaler that will keep the tank, supply lines, and carafe clean and free of mineral build-up. Depending on the water quality in your area, you may want to use the wash as often as every other week. Most public water sources will allow for a monthly washing cycle. You may use other cleaning and descaling products, but be sure that they are intended for home coffee machines. Commercial cleaning products, or those not designed for coffee machines, could damage your Ratio Eight and might invalidate the warranty. Upon the completion of the brew cycle, there may be some condensation build-up on the front of the machine. This can be easily removed by wiping down the machine with a lint-free cotton or microfiber towel. Please use caution, as the water vapor and shower head may still be hot. If left on the surface, this condensation should evaporate within a few minutes, but depending on the mineral content of your water, over time, spots may appear on the surface of the machine. Use the Ratio Machine Wash to remove any hard water spots on your machine.

1. Add half a bottle of liquid to the carafe, then add about 40oz/1150g of warm, not hot, water to dilute.
2. Pour into the Ratio water tank. Top up with more water to the fill line.
3. Brew one complete cycle.
4. Rinse all components. Repeat the brew cycle three times with clean water.
   In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of water. If swallowed, seek medical advice immediately and show the container or label.

MAINTENANCE

• Glass care
  The Ratio carafe is made of borosilicate glass, similar to laboratory glass. After each brew, rinse the carafe in warm tap water, using a drop of dish soap if you’d like. As a reminder, do not put the carafe in the dishwasher or microwave.
• Wood care
  The hardwood on the Ratio Eight is sealed with varnish that is formulated to handle extreme marine environments. Over time, the wood will develop a patina. To refresh the finish, use a clean towel to apply a natural oil intended for wood surfaces, such as butcher block oil. After 1-2 minutes, use another clean towel to buff the finish and remove excess oil. If you prefer a matte finish, use an ultra-fine steel wool (such as 0000 grit) to remove any gloss.
• Metal care
  Use a microfiber towel to wipe up water from the surface of the machine. Most coffee stains can be removed with a moistened towel. You may use diluted Ratio Machine Wash on the metal parts to remove coffee stains. Do not use an abrasive brush or scrub pad on the machine as it can scratch the surface.
