Warnings, Cautions, and Notes

Warnings

Failure to adhere to any of the warnings below could result in personal injury or damage to equipment. Improper use of PostProcess equipment may void the warranty. Read thoroughly before operating the machine. If the machine appears to be malfunctioning in any way, immediately push the EMERGENCY STOP button and refer to the Troubleshooting section of this guide. If the issue is not able to be resolved, call PostProcess support.

Caution should be used whenever working with electrically-powered equipment. If there is an emergency situation, it is important to note that hitting the POWER button does not disconnect the DEMI 400 Series from incoming power. It turns off the operating cycle only. To shut off power to the DEMI 400 Series, turn off the MASTER DISCONNECT SWITCH. For switch location, see image below under the “Electrical Safety” section.

Ventilation

PostProcess Technologies detergents are specifically formulated chemistry for maximized 3D printed support removal efficiency. Specific ventilation requirements can vary widely due to the local, state, and federal regulations, size of the install room, and existing ventilation (positive or negative).

To meet safety and environmental requirements, our solutions should be located in a well ventilated area, have a ventilation draw, and it is recommended that the post printing operations using PostProcess equipment and chemistry solutions have ventilation that is exhausted externally. Make up air should be provided from the facility where the equipment is located.

It is recommended that customers performing post printing operations have or consult with a responsible environmental health and safety person (such as an Industrial Hygienist) to determine and verify meeting environmental, health, and safety (EH&S) requirements.

PostProcess can provide the recommended ventilation requirements for each of our solutions as well as recommendations for ventilations consultation and EH&S / Industrial Hygienists.

Environmental Temperature and Humidity
Operating Environment Requirements:

• Temperature: 15°C to 27°C (60°F to 80°F)
• Relative humidity: 0% to 80%.
• Maximum altitude: 10,000 feet (3,048 meters)
• Pollution Degree 2
• Overvoltage Category II
  

Foreseeable Misuse

Do not operate the unit without proper grounding.
Do not place the power cord in a location where it may come into contact with water or liquids.
Do not heat or use detergent at a temperature greater than the flashpoint indicated on the detergent’s SDS. See Safety Data Sheet (SDS) for additional information on use.
Do not allow alcohol, gasoline or other flammable solutions near the machine. Doing so could cause a fire or explosion.
Do not attempt to disassemble or repair the machine.
Connect the unit only to power specified in the Connecting power to the DEMI 400 Series
Use only PostProcess detergents. Do not add any other liquid solutions to the machine.
Do not operate the machine without sufficient detergent in the tank.

Residual Risks

	Wear safety glasses or goggles. Use eye protection equipment that has been tested and approved by recognized national standards (or equivalent).
	When working with or near detergents, use disposable Nitrile gloves of at least 5 mil (0.005”) thickness. Change gloves after each use.

• Do not touch the detergent with bare skin. Use protective gloves, laboratory-style eyeglasses, and other necessary personal protective equipment when performing any operations including removing parts where skin could come into contact with the detergent.
• If bare skin comes in contact with detergent, at minimum thoroughly wash the body part with soap and warm, clean water. Always follow safety protocols outlined in the Safety Data Sheet (SDS).
• It is recommended that an eyewash station is near the DEMI 400 Series and any detergent storage areas.

Electrical Safety

Caution should be used whenever working with industrial-powered equipment. If there is an emergency situation, it is important to note that hitting the EMERGENCY STOP button does not turn off power to the DEMI 400 Series. It turns off the power to the DEMI 400 Series’s Motor/Pump Assembly, Thermal Heater, and Untrasonic Generator. The Safety Relay can only be reset manually when the Emergency Stop button has been pulled out by an operator and then by pressing the Physical Reset button or cycling power to the equipment (upon system initialization).

To shut off power to the DEMI 400 Series, turn off the MASTER DISCONNECT SWITCH, as shown below.

*The EMERGENCY STOP button should only be used when the solution needs to stopped quickly. For any other situation requiring the machine to be powered down, use the MASTER DISCONNECT SWITCH.
