Check the brew basket is assembled correctly. The wire rack must wedge firmly at the
boom of the brew basket.
1. Place the brewer on a dry, firm and horizontal surface with plenty of room above to
allow easy and safe connecon to the water source.

seng temperature, the screen display will show “Ready to Brew, watertemp.: ºF’’
when the tank has reached operang temperature. Some water will drip from the
sprinkler holder during this period because of thermal expansion and contracon

CLEANING
Regular cleaning ensures long life. For dirt or smudges on the brewer’s exterior, a damp
used. Be sure to unplug the appliance before cleaning.
DIRECTIONS FOR CLEANING GLASS DECANTERS
Use daily for best results.
1. Shake bole. Apply 3-4 squirts (approx. 1/4 oz. Per 1 gal. of liquid) Klearly Koffee into
the decanters (not included). Add very hot water (not boiling).
2. Use a carafe brush for best results on tough stains.
3. Empty soluon and rinse vessel thoroughly with clean, warm water. Air dry or wipe
clean before next use.
THE IMPORTANCE OF DELIMING
To prolong your coffee brewer’s life and maintain a consistent, quality product, regular
deliming is recommended. When hard water is heated, minerals are le behind which can
inhibit opmum performance. You should perform the following deliming process at least
every 6 months. If your water is extremely hard, monthly deliming is recommended.
DELIMING PROCEDURE
• Mix 10 oz. of fresh or condensed lemon juice with 32 oz. of water.
• Place brew basket in proper locaon.
• Place and empty container at the correct posion under the brew basket.
• Connect to the solenoid valve with an external bole water pump that substutes for
the water source. Then, pump the lemon juice mixture into the water tank by following
the brewing procedure.
• Let stand for 10 minutes and repeat 2-3 mes for best descaling results.
• Connect back to the water source and run the brewing cycle several mes with clean
water to rinse out the lemon soluon. Turn off the power and wait unl the water cools
down inside the boiler. Finally, use the drain pipe to release all remaining water in the
If the brewer suddenly stops working during a normal brewing cycle, deliming may be
necessary.
Klearly
Klearly Klearly Koffee is a simple, easy-to-use product that should be
used daily to remove or prevent oil residue and mineral build-up,
which turns rancid, causing bitter tasting coffee or tea.

DRAINING
When the brewer needs to moved, repaired, de-scaled, or emped for extended storage,
the remaining water in the boiler tank can be released following the steps below:
1. Unplug the power cord from the electrical socket and let the brewer cool down for at
least 40 minutes to avoid any burn injuries.
2.
front cover. Remove the front cover.
3. A white water pipe tube and hose shutoff clamp can be seen inside of brewer. (Figure 1)
4. Fasten the white shut off clamp at the end of the drain hose. (Figure 2)
5. Look for a connector in the front of water tube clips with a metal clamp. Press down on
the metal clamp and move slightly to the end of tube. (Figure 3)
6. Place the end of the drain hose in a container that has a capacity of 3 gallons or more.
7. Release the white clamp to drain water out from the tank.
8. When the water tank is empty, move the drain hose back to the original posion. Then,
press down on the metal clamp and move it back to the original posion.
9. Check that the white shut off clamp has been loosened.
10. Replace the front panel and ghten the screws.

BREWING TIPS
Fresh and good-tasng water is essenal since it makes up more than 98% of a cup of
coffee or tea. The brewing, pulse, extracon or pouring water me is primarily determined
by the ground size.
If the ground size is coarser, it causes under extracon and tasteless coffee. If the ground
size is too fine, it causes over-extracon and a bier taste. To get the best flavors from a
coffee, we suggest a medium grind (5-grain size).
