CO2-Recovery Plant 7 EN/2020
1.4 Important Safety Instructions
Hazard due to concentration of carbon dioxide!
Risk of suffocation and damage to health through carbon dioxide!
Low concentration (3-5 %) causes headaches and makes breathing difficult.
High concentration (7-10 %) causes headaches and nausea and leads to
unconsciousness.
Even higher concentration leads to unconsciousness and death.
The highest non-hazardous CO2 concentration is 5000 ppm. A higher
concentration is very dangerous to humans (German MAK Scale IV).
▪Operate the device only in well-ventilated spaces.
▪Installation of a CO2 gas detector is recommended.
Hazard due to electrical energy!
Unprotected electrical contacts, electrostatic processes, external effects on
electrical systems for example.
▪Only qualified specialists are allowed to carry out work on electrical
installations.
Personal protective equipment
Risk of injury from propelled parts!
▪ When operating the CO2-Recovery Plant, always wear safety goggles.
▪ All persons standing close to the CO2-Recovery Plant must wear suitable safety
goggles.
Risk of injury to the hands!
For example: Scratches, cuts, penetration wounds, burns and scalding due to hot or
cold sources of energy and/or the environment.
▪ Always wear suitable protective gloves when operating the CO2-Recovery Plant.
▪ Everybody in the vicinity of the CO2-Recovery Plant must wear suitable protective
gloves.
Risk of injury to the feet!
▪ Always wear suitable protective footwear when operating the CO2-Recovery
Plant.
▪ Everybody in the vicinity of the CO2-Recovery Plant must wear suitable protective
footwear.

CO2-Recovery Plant 8 EN/2020
1.5 Safety Components
The machine is equipped with the following safety component:
•Main Switch
•Flash Alarm
•Fused Electric Circuit
•Attention stickers on high voltage covers/valves.
•Pressure Relief Valves
For safety measures a CO2alarm should be installed in proximity of the CO2Unit. If, contrary to
expectations, a significant long-term leakage occurs in connection with the Dalum CO2Unit, the
CO2concentration will exceed the limit value and the alarm will start. Turn the Unit off with the
main switch, make sure to have the room ventilated well and leave the room. The CO2alarm
can also go off for other reasons that brings the concentration above the limit value of 1.5%, so
make sure to find the cause of the heighten CO2concentration.
1.6 Danger Points and Dangerous Situations
•Do not run the Unit without the compressor covers under any condition. If you notice that
the covers are loose; Turn the plant off, make sure the compressor is not moving. Then
tight them well before running the Unit again.
•This Unit is designed to run automatically, self-diagnosing and to automatically resume
production after stop, do not perform maintenance before turning the main switch off.
•In case of fire, do not open the control cabinet door and pull out the mains plug.
1.7 Arrival, Unloading and Positioning
Comply with transport regulations and have only people trained in goods handling and with
forklift license handling the CO2 Unit at arrival. . Dalum Beverage Equipment shall not be liable
for damage caused by non-compliance with the instructions and recommendations in this
chapter.
The safety instructions and the local accident prevention regulations in force must be observed
for all work.
1.7.1 Arriva and unloading
•At arrival of a DALUM CO2 Unit, packaging and product must be inspected for damages
and completeness according to the packing list. Have a copy of your signed transport
documents with all damages doted if any and send a Copy to DALUM on e-mail.
•The CO2 Unit will arrive in vertical position or in horizontal position on a wooden pallet
and packed in wooden crater. Unloading from the truck or trailer must be done with a
suitable forklift with sufficient carrying capacity, at least 600 kg.

CO2-Recovery Plant 9 EN/2020
•Secure load on transport vehicle against sliding or falling off.
•Do not stand underneath suspended loads or in the loading area.
•Be careful and move slowly on a flat, level, and hard surface when unloading and make
sure to clear the working areas.
•On horizontal transported Units open the end cover of the wooden box mindedly and
check the delivery for completeness against the packing list.
1.7.2 Positioning and erecting the Unit.
•Move the CO2 Unit and axillary equipment to the area it will be installed in the transport
packaging by forklift or pallet lifter at lowest possible elevation.
•Remove the wooden box by unscrewing the panes side by side with an electric screwing
machine. Remove the planks screwed on to the machine.
•On horizontal transported CO2 Units leave the wooden panel the machine is resting on
but unscrew the wooden pallet.
•For vertically transported machines remove all panels and bring the machine to its
installation position by forklift or pallet lifter and remove remaining wood.
•If the unit will be placed with one side against a wall, place the dehydrator side to the
wall with at least 0,5 meters gap to the wall.
•The floor must be cleaned and relatively level, hard and resistant to water.
•For horizontally transported machines bring the Unit in front of the final mounting
position in 90 degrees angel to the wall and the dehydrators on the upper side as it was
transported from the factory. Clear the area completely.
•Gently raise the machine by hand by 4 persons standing at the side of the unit lifting on
the panel at the top end of the Unit. The machine is bottom heavy so the weight per
person is acceptable. Remove the remaining wooden panel.
•If space allow for a forklift the Unit can be erected using a strap fixed to the top frame
and a fork on the lift. Be careful not to damage any parts on the unit.
•Level the CO2 Unit by adjusting the screws on the sanitary machine supports until the
Water Scrubber is 100% vertical.
1.8 Moving Plant
1.8.1 Before Moving
•Disconnect the complete power supply to the Unit, even for short distances.
•Close the supply and return valves and relief the pressure from the Unit.
•Close the manual CO2 Storage Tank transfer valve on the tank and disconnect the liquid
transfer line at the CO2 Unit.
•Disconnect the fluids supply and return pipes as well as drainage pipes.
•Close the fluid ports (gas ports, water ports, and coolant ports).
•If transported horizontally lay down the unit on a pallet about 60 centimetres from the
Unit and make sure it is in balance before moving.

CO2-Recovery Plant 10 EN/2020
1.8.2 Loading and Unloading
•Comply with transport regulations.
•Be careful and move slowly when loading with or without lifting gear and clear the
working areas.
•When loading or unloading the machine with lifting gear e.g., forklifts or pallet lifter,
ensure lifting capacity is sufficient, about 600 kg.
•Do not stand underneath suspended loads or in the loading area.
•Only use suitable transport vehicles with sufficient carrying capacity.
•Secure load on transport vehicle against sliding or falling off.
•Remove all parts attached for transport purposes and all packaging before the Unit is
started up after unloading.
•The machine can be transported vertically or horizontally, if horizontally it should lay
down on the compressor side with the frame resting on a Euro pallet about 60
centimeters from the bottom of the machine shoes or the bottom of the wooden transport
crates the machine is delivered in. If the machine is transported vertically, it can be lifted
on the bottom frame with a pallet lifter as the unit has a low point of gravity. Make sure
the machine is in balance on the lifting device before moving and move slowly.
