DISASSEMBLY- AND RE-ASSEMBLY ADVISE
For your safety first be sure the plug is
disconnected from the mains!
Removing the back cover:
- To remove the back cover, first remove the 4 screws.
- Open both doors, at the upper/lower right and left side the
screws can be found.
Picture 1.
- When the back cover has been removed all parts can easy be
reached.
Replacing the Lever Connector Assembly:
- Remove the screw that you can see on the front.
- Remove the hose from the pump unit.
- Now the lever assembly can be removed from the appliance.
- Reassembling follow above steps in reverse order.
Replacing the Doors:
- Remove the back cover.
- Unscrew the two screws that are holding the door.
- To re-assembly carry out steps backwards.
Replacing the Fan assy.
- When the Fan has to be
replaced, unscrew the 4 posi
screws and disconnect the
connector of the Fan.
- When re-assemble the fan
assy, be sure that the airflow
(see arrow on the Fan) is
appointing to the heat sink.
* Note: When the Fan became defect also Peltier
element has to be replaced or fully checked on
performance.
Due to overheating also the Peltier element will be
damaged.
Picture 2.Picture 2.
Replacing the Peltier element:
- When the Peltier element has to be replaced, first remove
the back cover and Fan assy.
- Unscrew the 2 screws located on the heat sink.
- The heat sink including Peltier element can now be
removed.
- With a small screwdriver the Peltier element can be removed
from the heat sink, some force maybe needed.
- Before placing the new Peltier element, clean the chiller
plate and heat sink thoroughly.
- Provide heat sink paste on
the heat sink and chiller
plate. With a plastic comb
(or plastic like a credit card)
carefully provide the heat
sink paste as equable as
possible.
- Place the new Peltier
element on the chiller plate
at the same position of the
removed Peltier element.
NOTE! It is important to place the Peltier element with
the right side on the chiller plate.
(see picture 4 for details)
- In other words, the cooling side
of the Peltier has to point to the
chillerplate and the warm side has
to point to the heat sink.
- Detail to check is the Colour of the
wires must be equal positioned see,
picture 4 for detail.
- Make sure the Peltier element is well
placed.
- Place the heat sink.
- Hold and place the heat sink with force against the Peltier
element.
- Tighten the screws alternate, to prevent damaging the
Peltier element for mounting lop-sided.
- While screwing wait some seconds so that the heat sink past
can be settled between the surfaces.
- Maximum force that maybe applied to tighten the screws
are: 0.6 Nm.
Replacing the pump unit:
- Start with disconnecting the air pressure hose and electrical
connections.
- Unscrew the 3 screws from the plastic pump bracket.
- To re-assembly carry out steps backwards.
NOTE! To prevent leakage at the connection side of the
hose, cut a small piece off the end of the hose.

Electrical circuit:
- When the appliance does not work, check the electrical circuit.
Working principle of the appliance
- Hereby a short description of the working principle.
- Beer, the Beer is stored in a plastic bag inside the Keg, see picture 5.
- The Beer only comes in contact with the tube connector and never with the appliance.
- When the tap unit and tube connector are connected on the Keg and the Keg is placed in the appliance, the Keg present switch
will be activated.
- Once the appliance is activated after approximately 10 seconds you will hear a pump running.
- The task of this pump is to fill the space between the plastic bag and the walls of the Keg with air and create an overpressure
(± 1500 mBar).
- Through the over pressure around the plastic bag (comparable like you squeeze into the plastic bag) the Beer will be pressurized
(sort of ) as well.
- By pulling the tap handle the tube connector hose will become opened and the Beer will flow out of the plastic bag via the tube
connector in to the glass.
- After this cycle the pump will start running to get back in the overpressure situation like described before.
- When the Keg present switch has been actuated also the cooling process (Peltier element) will be started.
- The temperature is measured by a NTC located near the Keg present plunger.

Procedure for checking cool down performance Peltier element.
- To ensure the Cool performance of the Peltier element is according specification the below test procedure have to be carried out.
Preparations:
1. Switch the appliance off and let it stabilize until it reached room temperature.
2. Remove under the base in the middle the rubber cap.
3. Remove the isolation foam under the removed cap, until the chiller plate becomes visible.
- Perform the temperature measurement, when the unit has reached the room/environment temperature.
1. Place a contact temperature probe against the chiller plate were the cap was removed.
2. Block the air inlet coupling at the Keg side, see picture 6 for location.
Picture 6.
3. Plug the appliance in the wall socket and bridge over the Keg present mechanically or electrically so the appliance will start.
4. When the appliance has started the pump will run shortly (in case the air inlet has been blocked properly)
5. Readout the temperature meter and note it down.
6. Keep the appliance switched on for 2 minutes, readout the temperature again.
7. If the temperature has decreased more then 6 °C, between the two measurements the cooling performance is OK, if not
please check again or replace peltier or Fan assy.
Final:
- When the appliance is checked and OK, fill the hole under the cap again with foam or other isolation material and place the cap
back under the base.

Problem Cause Repair solution
1Appliance doesn’t work 1. Power supply failed.
2. Keg present switch failed.
1. Check voltage output 10 V ±0.5 V.
(replace power supply)
2. Check/replace micro switch.

LED indication
no tap unit / air leakage
Software detection:
When the system detects no pressure rise during
running of the pump or detects a abnormal
pressure fall (duration of the measurement takes
300 seconds), the software will interpret that
there is no tap unit placed or there is air leakage
in the system.
Checks:
1. Place tap unit.
2. Is the pressure sensor function correctly?
3. Is air leakage noticeable in the system?
3Blinking RED LED
or pump is “to” often
activated.
(Air Leakage)
Check if air leakage is found internal the appliance.
1. Remove the Keg and tap unit.
2. Block the air Inlet coupling at the Keg side.
3. Actuate the KEG present switch after
±10 seconds the pump will start running
shortly (depending on air leakage).
4. Wait ± 300 sec.
5. Check if the pump is not running the air
leakage is probable external.
If the leakage is caused internally the following
parts must be checked.
1. Leakage hose and/or hose connections.
(Hairline cracks)
2. Leakage in air coupling.
3. Leakage in the pump and/or connections.
4. Defective air pressure sensor.
Air leakage external:
Parts that could cause the external air leakage
are: Tap unit, keg and air coupling.
1. Leakage in connection air coupling - Tap
unit.
2. Leakage in connection Keg - Tap unit.
3. Leakage in the Keg.

input to the Interface board.
Checks:
1. Is the micro switch function correctly?
5Cooling problems Cool down process takes very long.
Check if the user conditions were carried out
according the DFU.
1. Check if there is 10 cm free space around the
appliance.
2. Check if the ambient temperature did not
exceed 32 °C.
3. Check if the fan is turning well and there is
no blockage caused by dust or other particles.
4. Check if the Fan is correct placed (air flow
direction)
Unit doesn’t cool down.
Possible root causes:
1. Peltier element became defect.
2. NTC sensor became polluted or defective.
3. Fan, heat sink is full of dust.
4. Fan became defect.
Check/replace the defective parts.
1. Perform the cooling test as described on
page 6.
2. Clean the NTC See chapter SERVICE
TESTROUTINES step mode 2 how to
check the NTC system.
3. Check if the fan is turning well and there is
no blockage caused by dust or other particles.
4. Exchange fan.
