B.  Specifications as a sample of AMED Under Counter Bar Beer Cooler AMU-60L                                                                   

Power supply:  AC 220V , 50HZ/60HZ, 115V/60HZ

Compressor power:  1 / 4 HP

Water Tank: 30 L

Dimension: 420*420*600 mm

Net weight: 32 KG

Refrigerant R134a or R600a are optional


C.      Installation

1.     Machine should be installed onto the surface which is flat and solid, with sufficient ventilation, keeping away from heat, erosive sources and 250px from wallside.

2.     Lift off the machine cover and tank cover, then fill water into tank tiel the water level indicator (i.e. exceed the copper line about 50px). Distilled water are advised to be adopted. Spilling water onto the electrical parts/motor should be strictly avoided.

3.     Connect the CO2 pressure reducer and CO2 cylinder with wrench; one terminal of the CO2 supply hose should be connected with CO2 pressure reducer and another terminal should be connected with the tilting dispensing head by hose clamp. For easier installation, the CO2 supply hose should better be immersed into warm water for about 5 minutes before installation.

4.     Connect beer hose, which should be connected with the machine beer inlet at one terminal and dispending head at the other terminal and secured with the hose clamp.

5.     Connect beer line, which should be connected with the machine beer outlet at one terminal and beer tower beer inlet at the other terminal and secured with the hose clamp.

6.     Connect the tap with tower.


D.   Operation Manual

1.     After the machine has been installed and connected with electricity supply source, condensing unit and agitator motor will start to work. Under ambient temperature 25, first glass of beer generally can be dispensed out after 2.5hours.

2.     Connect dispensing head onto beer keg, open the CO2 cylinder valve and adjust the CO2 pressure reducing meter to 0.2MPa or brewery can adjust according to their own requirement.

3.     After adjustment of CO2 pressure, press down the dispensing head and turn on the taps to begin the beer output. First glass of beer in not drinkable as it is used for cleaning the beer line.

4.     Beer glass should be titled to tap and glass internal wall should be closed to tap outlet when dispensing beer. When beer reached 3/4 of glass, set the glass back to straight up-right position and keep appropriated distance from tap allowing perfect foam formed on top of beer. If foam is not thick enough, push the tap outflow handle backward to make more foam.


E.   Warning and Cares

1.     The cooler machine should be immediately switched off when voltage fluctuates too much or voltage is too low. Don’t re-start the machine for at least 3 minutes after electricity supply has been cut off.

2.     Disconnect the electricity supply before moving the machine, and titling should not be more than 45°.

3.     Disconnect the power to stop the machine, close CO2 cylinder valve, return back the compensating screw of CO2 pressure meter at the closing time.

4.     Thermostat has been pre-set to an optimum level, user should not adjust the thermostat as improper adjustment will lead to machine breakdown.

5.     Check water level and water quality per 15 days for normal operation and refill or change the water if necessary. Clean the beer lines by special cleaning tank filled with water and special cleaning detergent periodically and connect with the dispensing head, calibrate suitable CO2 pressure, circulate flushing for 2 times. Subsequent cleaning by clean water again and finally drying with CO2 to reduce damage, water splashing onto the agitator pump and other electric parts during water replacement or cleaning process should be strictly avoided.

6.     Check and clean the fan blade with a soft, dry cloth, brush or use a vacuum cleaner to remove accumulated dust to ensure well ventilation.

7.     Periodically clean the dispensing head and tap and the rubber seal should be immerged into approximate 50 warm water for about 5 minutes to keep the rubber flexibility.

8.     If the cooler machine will not be used for a long time, please clear the water tank and beer line before covering the machine and storing at a dry place.


F.      Trouble shooting


Possible Causes

What to do

1.Agitator motor, condensing unit and fan   motor don’t work after connection with electricity

a. socket without electricity supply or

plug contact problem

Check by electricity meter

b. electricity wire broken or metal

plate loose form contact

Replace the wire or metal plate

c. machine totally breakdown due to

faulty electricity supply

Contact manufacturer for repair service

2.Agitator motor works but condensing   unit and fan motor don’t work

a. fan blade of condensing unit are


Clear the blockage


b. thermostat defect or wire loosened

Replace thermostat or re-connect the wire

3. Condensing unit and fan motor work but   agitator motor doesn’t work

a. wire broken or metal plate


Replace wire or metal

b. starting relay or motor damage

Replace agitator motor or starting relay

4.Agitator motor works but compressor   irregularly switching on

a. voltage is low and protector relay


Improve electricity supply

b. bad ventilation lead to overheat

ambient temperature

Relocate the machine to make ventilation   condition better

5.Too much noise or vibration

a. machine is   grounded not firmly

Place the machine on a stable and flat   ground

b. near a vibration source

Remove the vibration source

c. fan blade distorted

Repair or change the fan blade

d. axle of agitator motor curved

Repair or change the motor

6.Cooling effect is not performed   satisfactorily

a. voltage is too low

Improve electricity supply

b. insufficient refrigerant

Contact special technician to check and   repair

7.No cooling effect

a. system blocked or all refrigerant

leaked away if compressor still


Repair and check by special technician

b. wiring defect or compressor defect

if compressor don’t work

Repair and check by special technician
