When the machine is in use, some parts of the machine will become very hot. Ensure the
line of cord does not touch the hot parts. The user should also be careful not to touch the hot
parts.
Keep the unit away from the children.
Children under the age of 18 years should be supervised to ensure they do not play with the
appliance.
Appliances can be used by persons 18 years and above with reduced physical, sensory or

◆Installation: (Initial Set-up)
Please check the Brew Chamber is assembled correctly. The spring
(Wire Rack) MUST wedge firmly at the bottom of the Filter Basket.
1. Place the Machine on a dry, firm and horizontal surface with
plenty of room above to allow easy and safe connect to the water
source.
2. Plumb the unit in to the water source. A qualify water filter
or softer water is recommended. The brewer must be
connected to a cold water system with operating pressure
between 20 and 90psi (0.138 and 0.620 MPa) from a 1/2”or
larger supply line. A shut-off valve should be installed in
the line before the brewer. Install a regulator in the line
when pressure is greater than 90PSI to reduce it to 50pci.
The water inlet fitting is 1/4”flare. A tight coil of copper
tubing in the water line will facilitate moving the brewer to clean the counter top. We do
not recommend the use of a saddle valve to install the brewer. The size and shape of the
hole made in the supply line by this type of device may restrict water flow.
3. Insert an empty funnel into the funnel rails.
4. Place an empty Server at correct position under the Brew Chamber.
5. Plug the machine to the power source.
6. Turn on the main ON/OFF switch located on the back side of brewer. The display will
show “Insufficient water storage in the tank”and “Turn on enable brew on/off switch and
tank filling.
7. Push 【4】enable brew on/off switch. Then the water will flow into the tank and stop when
the tank is filled to its capacity. Display will show “Please wait, tank filling”until tank is
filled with water.
8. Wait approximately 15 ~ 20 minutes for the water in the tank to heat to the setting
temperature. Display will show “Ready to Brew, water temp.: ℉’’ when tank is reach
operating temperature. Some water will drip from the funnel during this time; this is due to
expansion and should not occur thereafter.
9. Place a small container under the faucet. Then open the faucet handle and release it when
you hear thank refilling.
10. The machine is now ready for use.
11. During above operation, it is normal to hear some brewing and pumping sounds and to see
some water vapor coming out of the machine.

Calibrate water volume
“Calibrate water volume” programming is at the last second options of function setting. Before
conducting the “calibrate water volume” procedure, the container, measuring cup and electric
scale are necessary to prepare.
Actual calibration Follow the screen indication, actual measuring the water out volume
for 4 minutes. Then, input the actual measuring value. After measuring,
please convert to oz per minute and remember this parameter to facilitate
future adjustment.
Input calibration data Provide the data to qualified person, or when conduct the simulation
testing, input experience value to save actual mearing time. The
standard value is approximately 1.1L per minute.
Before calibrate water volume, the container, measuring cup and electric scale are
necessary. Please remove filter pan to avoid any inaccuracy when doing calibration.

Factory Default
When the machine setting occurs the confusion or has new recipe or resets the machine to
upgrade the program, please restore to the factory default first.
Option: Hot Water Faucet
The machine that equips with hot water faucet, the user can open the faucet handle to get hot
water.
When the water temperature in the boiler tank is higher than the brewing temperature, the
user can open the faucet and release some water in order to reduce the temperature in the
boiler tank.
WARNING! HOT WATER!
WARNING! REMOVE FUNNEL SLOWLY!
Tank Drain
When the machine needs to move, repair, de-scaling, or empty the remained water in the
boiler tank, please follow the below steps to release water:
Unplug the power cord from the socket and cool down the machine at least 40 minutes to
avoid any burn injury during released water process.
Remove two black fixed pillars from machine bottom and loosen the 6 screws of the
front cover. Then the front cover can be removed. (This is for AIG0DA model).
White water pipe tube and hose shutoff clamp can be seen inside of machine. (Figure 1)
Fasten the white hose shutoff clamp at the end of the drain hose. (Figure 2)
The connector in the front of water tube clips with a metal clamp. Please press down
the metal clamp and move slightly to the end of tube. (Figure 3)
Place the end of the drain hose in a container that has a minimum capacity of 405oz or
more.
Release the white clamp to drain water from the tank.
When tank is empty, leave the white clamp loose and connect drain hose back to original
position, then press down the metal clamp and move it back original positon.
Please reconfirm that the hose shut off clip is at the loosen status.
Replace the front panel and tighten the screws.
Reinstall the black fixed pillars back to machines bottom.

Cleaning
It is important that the Machine and its accessories are kept clean after using.
For dirt or smudges on the Machine, it is better to clean them with a soft damp cloth, and if
necessary, with a non-corrosive and/or non-abrasive detergent or cleaner.
The filter pan and container pot might have some coffee or tea spots on them; clean them after
using daily is the best way to maintain the machine and its accessories.
If the coffee / tea spots accumulate on the filter pan or container pot over a while, please follow
the below steps to clean:
Put the filter pan and container pot into water and immerse for several hours.
The glass jug and filter pan should be washed in warm soapy water.
If necessary, clean with a non-corrosive or non-abrasive detergent.
Repeat to rinse until all remained detergent have been cleaned out.
De-sediments
After long term use, as the general water has some minerals, the limescale could build up in
the boiler; water tank and brew spray head, especially in the area that is belonged to hard
water quality. When inside of machine builds up too much limescale, it will affect the
normal operating of machine. Therefore, we recommend that your coffee maker is descaled
at the regular intervals, e.g. every 3-6 months or as required. If the water filters through
more slowly than usual, it is a sign that descaling is necessary. Please follow below steps
to de-sediment:
Melt 300 ml citric acid to a pail of warm water (around 2000ml) or dilute 2000ml
condensed lemon juice to 1 liter of warm water.
Place filter basket in proper position.
Place an empty pot at the correct position under the filter basket.
Connect to the solenoid valve by using an external water pump instead of water source.
Then, pump the citric acid solution into water tank by following the same brewing
procedure.
Standing for 10 mins, repeat 2~3 times of descaling steps if necessary.
Connect back to the water source and run the brewing cycles for several times with
water in order to clean away the citric acid liquid remained in the water tank. Turn off
the power and wait until water cool down inside of boiler. After that, using drainpipe
to release all remainder water in the boiler until the residual lemon flavor is completely
removed.
During the descaling process, please assign the technical person to guard the whole
process.
During the descaling process, wear appropriate gloves and goggles are necessary to avoid
any acid liquid splash.
In case if any acid liquid splash to the eyes or skin, please use a great quantity of water to
wash and go to the hospital immediately.

Secret Recipe –Coffee & TEA
Fresh, good-tasting water is essential since it makes up more than 98 percent of a cup of coffee.
The brewing, pulse, extraction or pouring water time is primarily determined by the grind size.
A longer brewing time is required for the water to penetrate the larger grind particles. The grain
size of grinding also affects the coffee taste. The fine grinding may cause over extraction and a
bitter taste. The coarse grinding may cause under-extract and tasteless. We suggest medium
grinding (5 grain size) will be the best. Never reuse the coffee filter paper and coffee powder.
