The Catler CM 4012 is a sophisticated coffee maker designed for brewing filtered coffee, offering both automatic and manual brewing modes, a built-in scale, and hot water dispensing capabilities. It prioritizes user safety and convenience with several features and warnings.
Function Description
The primary function of the Catler CM 4012 is to brew filtered coffee. It achieves this through a precise heating and dispensing system that ensures even saturation of ground coffee. The device also features a hot water dispensing mode, allowing users to heat water to a desired temperature for other uses. A built-in electronic scale is integrated to accurately weigh ground coffee, contributing to consistent brewing results. The coffee maker includes a delay start function for both automatic and manual brewing, enabling users to program brewing to begin at a specific time. An automatic stand-by mode conserves energy when the appliance is inactive.
Important Technical Specifications
The water tank has a maximum capacity of 1 liter (1000 mL). The brewing temperature can be set in the manual mode from 80 °C to 98 °C, while the automatic brewing mode is preset to 93 °C. The coffee-to-water ratio in manual mode can be adjusted from 1:10 (strong coffee) to 1:20. The built-in electronic scale has an accuracy of +/-3 g per 1 kg, with a range of 0 – 3 kg. The appliance is designed for household use and operates on a properly grounded electrical socket. It is equipped with a safety thermal fuse that automatically cuts off the electrical circuit in case of overheating. The descaling indicator light flashes after 50 brewing cycles, prompting maintenance.
Usage Features
Before First Use:
Upon unpacking, all packaging and advertising labels should be removed. The silicone cover, carafe, and stainless-steel filter should be washed with warm water and a small amount of dishwashing detergent, then rinsed and dried. The coffee maker body, water tank, and lid should be wiped with a slightly moistened sponge and dried. A crucial step before first use, or after a long period of non-use, is to flush the coffee maker with clean, hot water. This involves filling the water tank to the Max mark, placing the carafe under the dispensing vent (without a filter), turning the rotary knob to "Hot Water," setting the temperature to "100 °C" using the ▼/▲ buttons, and pressing the button to start heating and dispensing the water.
Clock Setting:
After plugging in, the display will flash "0:00." The ▼/▲ buttons are used to set hours and minutes, with the button confirming each setting. Correct clock setting is essential for the delay start functions.
Filling the Water Tank:
Only clean, cold water should be used. The water tank lid is removed, water is poured in, ensuring levels are between the minimum and maximum marks, and the lid is replaced. A sensor at the tank bottom measures water temperature, so proper lid placement is vital for efficient heating.
Automatic Coffee Brewing:
- Fill the water tank with clean, cold water, observing min/max marks.
- Place the stainless-steel filter into the carafe neck, insert a V-shaped paper filter (size 4), and place the carafe into the coffee maker.
- Turn the rotary knob to "Brew Mode A/M," select "AUTO" using ▼/▲ buttons.
- Press TARE, remove the carafe.
- Add the desired amount of ground drip-coffee into the paper filter.
- Place the carafe back; the display will show the weight of the ground coffee.
- Press the button to start. The button will flash, and the coffee maker will heat water, displaying the actual temperature.
- During brewing, the preset temperature (93 °C), coffee-to-water ratio (1:15), or coffee volume can be checked by rotating the knob.
- Once 93 °C is reached, water is slowly dispensed through a rotary mechanism for even brewing.
- After an initial 30-second brewing pause, water dispensing resumes until the total water amount is 15 times the ground coffee weight.
- The display will show the total coffee amount.
- After all coffee has dripped, carefully remove filters and place the stainless-steel filter in its holder to cool.
Manual Coffee Brewing:
- Fill the water tank with clean, cold water, observing min/max marks.
- Place the stainless-steel filter into the carafe neck, insert a V-shaped paper filter (size 4), and place the carafe into the coffee maker.
- Turn the rotary knob to "Brew Mode A/M," select "MANUAL" using ▼/▲ buttons.
- Press TARE, remove the carafe.
- Add the desired amount of ground drip-coffee into the paper filter.
- Place the carafe back; the display will show the weight of the ground coffee.
- Set parameters:
- Water temperature: Turn the rotary knob to "Temp," use ▼/▲ buttons to set between 80 °C and 98 °C. Press the button or wait for the display to stop flashing.
- Coffee-to-water ratio: Turn the rotary knob to "C/W Ratio," use ▼/▲ buttons to set between 1:10 and 1:20. Press the button or wait for the display to stop flashing.
- Press the button to start. The button will flash, and the coffee maker will heat water, displaying the actual temperature.
- During brewing, the set temperature, ratio, or coffee volume can be checked by rotating the knob.
- Once the set temperature is reached, water is slowly dispensed through a rotary mechanism.
- After an initial 30-second brewing pause, water dispensing resumes until the total water amount matches the set ratio.
- The display will show the total coffee amount.
- After all coffee has dripped, carefully remove filters and place the stainless-steel filter in its holder to cool.
Delay Start (Automatic/Manual Brewing):
- For automatic brewing, follow steps 1-6 of "Automatic Coffee Brewing." For manual brewing, follow steps 1-7 of "Manual Coffee Brewing."
- Turn the rotary knob to "Program." The display will show the last delay start setting.
- Use ▼/▲ buttons to set the desired start time, confirming with the button.
- Press the button to activate delay start. The display will show "AUTO" or "MANUAL" and "PROG," then revert to the actual time and "PROG."
- At the set time, brewing will commence according to the programmed parameters.
Hot Water Dispensing:
- Fill the water tank with clean, cold water, observing min/max marks.
- Place the carafe under the dispensing vent (no filter needed).
- Turn the rotary knob to "Hot Water." The display shows the current water temperature.
- Use ▼/▲ buttons to set the desired water temperature (higher than current).
- Press the button to start heating. The display will show the actual water temperature.
- Once the set temperature is reached, the coffee maker will dispense the entire amount of hot water into the carafe.
Built-in Scale:
The electronic scale is precise and temperature-sensitive. Always press the TARE button before weighing ground coffee to ensure accuracy. Avoid placing heavy objects (over 3 kg) on the scale to prevent damage.
Maintenance Features
Descaling:
- The descaling indicator light will flash after 50 brewing cycles.
- Fill the water tank to the Max mark with clean water and add the required amount of citric acid.
- Turn the rotary knob to "Clean." The display will show "100 °C."
- Press the button to start heating. The display will show the actual water temperature.
- Once 100 °C is reached, the coffee maker will dispense hot water until the tank is empty.
- The descaling process is complete when the indicator light stops flashing.
