GB
FLAMMABLE
Isopropyl alcohol, the intended cleaning solvent, is highly flammable in both liquid and vapor states.
The operating environment must be free of open flame, sparks, other ignition sources or excessive heat.
Failure to comply increases risk of combustion and serious harm of operator or third parties.
CAUTION
Isopropyl alcohol, the intended cleaning solvent, can be damaging to the human body through ingestion,
inhalation and bodily contact. Read and adhere to the safety information detailed on the isopropyl
alcohol container’s label or contact the organization responsible for your local hazardous materials
regulations for more information.
Mandatory safety equipment:

residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the User Manual, may cause harmful interference to radio communications. However,
there is no guarantee that the interference will not occur in an individual installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment o and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that of the receiver.
• Consult the dealer or an experienced radio/TV technician for help.
If this equipment is receiving interference that aects the cara Print Clean, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the unit or emitting equipment.

3 Intended Use and Proper Operation
3.1 Intended Use
The cara Print Clean is an automated cleaning system that utilizes an agitated, contained volume of isopropyl
alcohol (isopropanol) to clean excess uncured 3D printing liquid material from 3D printed parts (“parts”).
Cleaning of parts and unit use shall be done by trained professionals in 3D printing laboratory environments.
The unit is not suitable nor intended for any purpose other than cleaning in these stated industries or recreations.
3.2 Proper Operation
CAUTION
The unit is suitable to be set up and operated in clean laboratory environments. The unit has been designed for
continuous operation.
• Only 3D printed parts made of cured resin shall be washed in the cara Print Clean. Cleaning anything that is
not a resin-based, 3D-printed part will void the warranty.
• Do not excessively clean a 3D printed part by continuing to expose it to isopropyl alcohol past the point of
removing the uncured resin. Over exposure may lead to structural degradation by weakening the part’s cured
resin.
• Ensure that the outer container, inner container, inner container plug, hanging arm, Build Table and lid are all
secured in their proper positions before starting a cleaning cycle.
NOTE
Isopropyl alcohol is the only solvent suitable to be used in the cara Print Clean. Using any other substance as the
solvent will void the warranty. Kulzer GmbH is free in qualifying and release alternative cleaning solvents beside
Isopropanol. For information about released cleaning solvents please download and observe Kulzer cara cleaning
guide (see chapter 1 too).
NOTE
Do not modify the firmware and hardware of device.
