Danger!Risk of personal injury and equipment damage due to leaking refrigerant
In accordance with DIN EN 378 standard, part 1, the refrigerant used with this unit, R290
(propane), is classified as safety group A3. It is not poisonous and not caustic or
corrosive. However, it is combustible and highly flammable. As a result, a potentially
explosive atmosphere may occur in the case of leaks.
The refrigerant is heavier than air and, consequently, accumulates at the bottom and may
enter lower lying areas (e.g. sewage systems). At high concentrations, this may lead to a lack
of oxygen, resulting in a risk of suffocation. Lower concentrations may have a narcotic effect.
The refrigerant has a very slight, somewhat sweet smell.
 Avoid any damage to components that carry the refrigerant
 If you suspect any leaks, however small, shut down the unit, air the room well and
inform your service partner.
 Do not allow direct contact with the skin of any leakingrefrigerant.
 Fire, open flames and smoking are prohibited.
 If you begin to notice any smell, leave the room and alert the fire service
Notice! In particular, safety standards are to be observed in their scope of validity
(e.g. EN 60335-2-75).
2 Transport and packaging
Choose a suitable packaging when returning the unit itself or one of its components to Cornelius Deutschland
GmbH, e.g. for repairs. In particular, make sure that the unit and any components are protected from
shock/impact, moisture, dirt and electrostatic discharge (ESD). This will prevent transport damage to the unit
and to the components, for which the manufacturer shall assume no liability.
Caution!
Component damage due to freezing liquids
Ambient temperatures that are below freezing will lead to the freezing of any water or cleaning
agent residue remaining inside the unit. This will lead
to damages of internal components.
-Before shipment, storage or relocation of the unit, the unit is to be cleaned and the cleaning
solution is to be fully drained from the unit.
2.1 Storage

6 Putting into and out of Operation
6.1 Putting into Operation
Before starting operation of the unit the transport lock must be removed.
In order to ensure the proper function of the unit, please follow the below outlined points in their order.
Comply with the cleaning regulations defined by local laws before beginning each operation.
Connectors must be cleaned every time prior to attaching a beverage container.
Connect coupling to beverage container.
For soft drink note: gray coupling = CO2, black coupling =beverage/syrup
Open the valve of the CO2-cylinder and the pressure regulator. Check the CO2-pressure on the pressure
regulator.
It should be within the following standard values:
Syrup: 0,42-0,49 MPa (4,2-4,9 bar)
Carbonator pressure: 0,52-0,58 MPa (5,2-5,8 bar) cold carbonation
Diet/light-beverage: 0,21-0,28 MPa (2,1-2,8 bar)
Set the CO2-pressure by turning the control screw:
To increase the pressure: Clockwise
To reduce the pressure: Counterclockwise
Afterwards check the CO2-lines for leaks by closing the CO2-valve. The pressure (high pressure gauge)
displayed at the pressure regulator should not drop. If it does, notify the service technician immediately! Do
not forget to re-open the CO2-valve if no leakage is evident.
Open the water feed line and check the flow pressure. Standard value: 0,17-0,35 MPa (1,7-3,5 bar).
Set flow pressure at the control screw on the water pressure regulator:
To increase the pressure: Clockwise
To reduce the pressure: Counterclockwise
Check the beverage/syrup lines for leaks. Only a visual inspection is possible. If liquid is leaking, call a
service technician.
Close the water feed line. The pressure display should not drop. If it does, notify the service technician
immediately! Check the incoming waterline for leaks. Do not forget to re-open the water feed line if no
leakage is evident.
6.2 Turning on the Unit
The water bath must be filled to the overflow with tap water. Refer to the technical data for the amount
required.
Take care, that no water runs into the agitator motor. Reference: Use for this a suitable funnel and filler
tube.
To prevent algae from forming in the water, add the disinfectant Molco (PN 14-9670-150). The 150 ml
container of disinfectant is sufficient for 30 liters of water.
Insert the mains plug for the cooler into the socket outlet with an earthed contact.
Units with water bath are ice bank controlled. These units start working automatically after the water bath is
filled with water. The compressor will cycle off after the ice bank has been built. (full ice bank capacity). The
control board of the unit has a time delay for switching on and off the cooling system when it runs in ice

Version A, 24.09.2019, Index 0
bank mode. After the cooling system is switched on the running time is no less than 5 minutes. Switch off
signals will be ignored in this time. After the cooling system switches off, the delay is no less than 3
minutes. Switch on signals will be ignored in this time. The 3 minutes delay occurs when turning on the unit
and after a break in power supply. This unit contains a 3-pin ice bank probe.
Post-mix units include a carbonator pump which switches on automatically and fills the carbonator bowl.
The carbonator pump switches off when the water has reached its highest level in the carbonator bowl but
after no more than 5 minutes. Long run periods are signs of leaks or insufficient water. It is then only
possible to turn the pump back on by executing a network reset (pulling out the mains plug briefly).
The carbonators in post-mix units are protected against running dry. If the flow rate quantity is so large that
the ”empty electrode” is activated, then the carbonator bowl is empty. In such cases voltage supply for the
post-mix valves will be switched off. A beverage withdrawal is only again possible if the carbonator bowl is
filled.
Release air from the carbonator bowl by pulling the safety valve for about 2 to 4 seconds.
6.3 Purging the Syrup Systems
Purging the syrup systems
Place a cup under the nozzle.
Manually open each syrup valve in turn and observe syrup flow. Purging is completed when all air is
removed from the system. If syrup continues to show air bubbles, check tightness of line connections.
6.4 Adjusting the Water-to-Syrup Ratio for Post-mix
Adjust the water flow rate on the post-mix valve in accordance with the valve supplier specifications.
Note: Allow the refrigeration unit to operate until minimal amount of ice has formed on the evaporation
coils, making this adjustment. Alternatively, allow the full ice bank to form (compressor cycle off) before
adjusting the ratio. The drink temperature should not be higher than 5°C.
The water-to-syrup ratio is measured by use of a ratio cup having two champers into which the soda and
the selected syrup are dispensed. The ratio, if incorrect, is adjusted by turning the related syrup flow
regulator adjusting screw located near the solenoid valve.
To increase the syrup flow rate: Clockwise
To reduce the syrup flow rate: Counterclockwise
6.5 End of Operation (End of dispense-time)
It is imperative that the CO2-cylinder and water line be turned off each time operation is ended.
Be sure to open again before continuing at operation.
6.6 Daily Inspection
Check whether carbon dioxide and water lines are open.
Check the beverage/syrup lines for leaks. Only a visual inspection is possible. If liquid escapes, call a
service technician.
Check the CO2-lines for leaks by closing valve on the CO2-cylinder. The inlet pressure indicated on the
pressure regulator should not drop. If it does, call a service technician immediately.
Do not forget to re-open the CO2-cylinder valve afterwards.

6.7 Taking out of operation (Vacation, end of season)
Perform the following steps in case of protracted standstill periods:
Close the CO2-cylinder, the CO2-stopcocks on pressure regulators and the water feed line.
Pull the mains plug out of socket outlet with earthed contact.
Detach the couplings from beverage containers.
Have the system emptied and cleaned.
Only trained specialists are to carry out this procedure.
7 Cleaning and Disinfection Directions
7.1 Cleaning Directions
Comply with the valid national regulations for cleaning bar equipment at the particular installation site.
Clean connection parts and tap fittings in advance whenever making connections or changing the type of
beverage. Clean parts coming into contact with air and beverage (e.g. dispense nozzle) on a daily basis.
The condenser fins must be cleaned in regular intervals. These vary according to the amount of dirt in the
air at the installation site (approximately every three months). This is best done with a brush and a vacuum
cleaner.
The water level in the water bath must be checked regularly and the contents must be exchanged at least
once annually. Algae formation can be reduced by adding disinfectant (order number 14-9670-150). For a
30 liters water-bath one disinfectant container is sufficient.
The unit is to be emptied and cleaned by trained person only based on the following recommendations:

7.2 Cleaning and Disinfection Procedure before use
In order to achieve a proper hygienic performance of the dispense equipment, it is crucial to run the initial
and recurring sanitization procedure (intervals according to DIN 6650-6) on all product and water lines of
the system.
Attention! Cleaning / sanitizing agents are harmful and may cause severe health injuries! During the
work with any agents make sure to always wear proper clothing (gloves, safety goggles,
etc.). Special attention must be taken during the flushing of the agent at the dispense
valves. It must be made sure, that no operator uses the dispense equipment during
sanitation (e.g. use clear signs on the valves, etc.)!
Take care of an adequate behaviour towards hygiene while working on the equipment
(e.g. disinfecting hands prior to work, etc.) in order to professionally deal with the matter.
The unit should be cleaned / sanitized starting as close as possible from the mains water
connection (wall outlet) to make sure that also the tubing is being treated.
Remark -> Water filters:
In case the system is equipped with a water filter, the filter cartridge needs to be removed before doing the
cleaning / sanitization and replaced by a blind plug that allows bypassing the filter. Do not use any empty
service filter cartridges to flush the sanitizing agent into the system, as this will not allow a proper and consistent
level of sanitizing agent in the unit.
In addition, the high levels of agent passing through the dispenser when using such cartridges may damage
components such as sealings, O-rings, etc. in the dispenser.
Remark -> Carbonator- / Circulation pumps
With units such as Triton, Apexx and Energize the carbonator- and soda circulation pumps must be turned off
during the cleaning / sanitization process (otherwise foaming issues will occur).
Remark -> Stillwater lines inside the cooler
In case your equipment has still water lines, it must be made sure that these are also being cleaned / sanitized.
In case your equipment currently does not use Stillwater, the line must be equipped with a stopcock to manually
drain sanitizing agent from this tube.
In case the Stillwater line is in general not being used on the cooler, it is recommended to disconnect this line as
close as possible from the water cycle and close the water line with a blind plug (this avoids areas within the
circuit which might not be sufficiently flushed).
Remark -> Electrical post-mix valves, which cannot be manually operated
These type of taps must be operated electrically. When doing this, it needs to be considered that on some
dispense equipment the 24V electrical power supply to the valves is cut, when the empty electrode in the
carbonator bowl is reached. In that case the empty sensing must be bypassed, by e.g. short circuiting all
connectors on the plug of the level probe connection.
Remark -> CO2- or Water pressure sensors on the dispense equipment
Depending on the type of equipment you may have CO2- or water pressure sensors installed, which will in case
of low CO2or low water supply cut the 24V power supply to the valves.
In order to still be able to operate the system during the sanitization process, it is required to short circuit such
sensors (make sure to put them back into operation after service).
Remark -> Post-mix valve blocks
It is recommended to clean / sanitize the valve blocks separately. Especially valve blocks with an integrated
stop cock (e.g. Lancer block) need special care, as the gap in the stop cock allows bacteria to collect, which
might not be sufficiently treated with the sanitizing agent.
In case the dispenser is out of operation (without cooling) for more than 10 days, it is necessary to run the
cleaning- and sanitization procedure prior to putting the unit back into operation.
Should it be necessary, to open a once sanitized system again (e.g. to install a new water filter)
all opened connections must be disinfected with a sanitization spray prior to reconnecting.

A.) Flushing-in of sanitization agent (e.g. P3 Ansep CIP from Ecolab)
1.) Syrup Lines
1.1) The product lines filled with syrup must first be flushed with water. For this an external
water distributor can be used to connect and flush several syrup lines simultaneously.
The post-mix valves should be operated on the syrup side only for flushing.
Attention! Gas driven syrup pumps must not see any positive pressures on the
incoming side of the pump, as this may damage the pumps.
1.2) Connect the water distributor to the CO2supply in order to drive the water out of the
syrup lines. This avoids that the sanitizing agent is being diluted in the tubing.
Afterwards close the CO2 gas and depressurize the complete system again.
1.3) Fill your cleaning tank with the cleaning / sanitizing agent according to the mixing ratios
given by the manufacturer of the agent.
(e.g. when using P3 from ECOLAB -> 50ml for 1 litre water = 5% solution)
In order to achieve a proper mixing in the cleaning tank, it is recommended to first fill
in the agent and then top-of with clean water.
1.4) Connect the syrup lines to the cleaning tank and dispense cleaning / sanitization agent
from every single dispense valve. Make sure that agent leaves from all installed taps.
2.) Water Lines
2.1) Close the water- + the CO2supply to the unit and depressurize the system with the taps
2.2) Disconnect the water supply to the unit and cut the power supply to the carbonator
pump in order to avoid dry running of the pump (e.g. by pulling the plug of the pump).
2.3) Connect the water line feeding the dispenser to CO2 gas pressure and drain all water from the tubing of
the system. This ensures that the sanitizing agent that is afterwards flushed into the dispenser is not
being diluted e.g. in the carbonator bowl.
Afterwards close the gas supply again and depressurize the system.
2.4) Connect the cleaning tank to the water inlet of the dispenser and pressurize the tank
with approx. 3 bars pressure (Attention! Remove any water filters before doing this!).
2.5) Pull the safety relieve valve on the carbonator bowl and carefully let some sanitizing agent leave the
valve. This ensures that the carbonator bowl is flooded completely with the sanitizing agent all the way
to the top.
Attention! : Avoid that excessive amounts (= >50ml) of agent is being introduced into
the water bath, as this will carry the risk of corrosion of metal parts in the water bath.
In case larger amounts were spilled, the water in the water bath needs to be replaced.
The LOOP post-mix cooler works with a membrane / diaphragm pump
please make sure the pump is in operation when the sanitizing agent
is being flushed into the unit. This will ensure that all parts of the pump will come into
contact with the sanitizing agent.
2.6) Flood the complete dispense system with the cleaning / sanitizing agent by operating
the post-mix valves. Ensure that on all valves clearly visible agent is being drawn.
Effect- / working time for the cleaning / sanitizing agent is min. 20 minutes!
In the meantime remove the dispense nozzles from the valves and sanitize them
manually by putting them for 20 minutes into sanitizing agent.
In case it is seen that the nozzles are heavily dirty, clean the nozzles mechanically
by using a clean brush and sanitization agent.

B.) Flushing-out of sanitization agent
1.) Syrup Lines
1.1) Disconnect the cleaning tank and bring out any remaining sanitizing agent from the syrup lines by
using CO2gas. Afterwards close the CO2supply and depressurize the system via the dispense valves.
1.2) Connect the water distributor and sufficiently flush clean water through the syrup lines (for this please
open only the syrup side of the dispense valves). In case a hygiene water filter is being used with the
dispenser, it is recommended to use for this flushing the water coming from the hygiene filter.
Attention! It must be ensured, that no cleaning / sanitizing agent remains in the dispense system
after service (risk of health injuries)!
The proof that all agent residues have been removed has to be tested with indicator
or test papers (contact agent manufacturer). The results have to be documented.
1.3) Connect the syrup containers again to the syrup lines and dispense syrup on the post-mix valves until
a consistent flow of syrup occurs again.
2.) Water lines
2.1) Pressurize the water line to the cooler with CO2pressure and dispense all sanitizing agent from the
valves. This makes it easier to flush out any remaining agent from the system.
2.2) Close the gas again and depressurize the unit via the dispense valves.
2.3) Install a new water filter cartridge and reconnect the unit via the filter to the mains water line again
(refer to filter manufacturer guidelines in case the filter needs priming prior to use).
In case a hygiene filter is being used on the dispenser, it must be ensured that the new
filter cartridge is inserted prior to flushing the system with water. This ensures that a
just sanitized system is not being contaminated again by using poor quality mains water
to flush out any remaining sanitizing agent.
Spray the filter head and the connecting position of the filter cartridge with an adequate
sanitizing spray to avoid any introduction of bacteria again.
2.4) Open the mains water supply. Pull the safety relieve valve on the carbonator bowl until
only clean water leaves the valve, to ensure that there are no residues of sanitizing
agent left in the head area of the carbonator bowl.
2.5) Open the CO2 gas supply to the carbonator and reconnect the carbonator pump to the
power supply.
2.6) Dispense sufficiently water from the post-mix valves to ensure that no sanitizing agent is
left in the system.
Depending on the unit type (Over counter dispenser / large soda circuit installation with
long python runs, etc.) the amount of water that needs to be dispensed may vary.
Attention! It must be ensured, that no cleaning / sanitizing agent remains in the
dispense system after service (risk of health injuries)!
The proof that all agent residues have been removed has to be tested with indicator
or test papers (contact agent manufacturer). The results have to be documented.
Dispense from each tap a few beverages to fully put the system back into operation again. The
cleaning / sanitization procedure must be documented accordingly and the
documentation must remain at the cooler (this may vary depending on local regulations).
