2.3 Equipment Usage
2.3.1 Intended Use
Use of Nordson ASYMTEK equipment in ways other than those described in the documentation supplied
with the equipment may result in injury to persons or damage to property.
2.3.2 Misuse
The UV-9 is designed for in-line installation where equipment adjacent to the oven, upstream and
downstream, serves as a shield to protect operators from escaping visible light and UV and IR radiation
emitted from the lamp(s) through the entrance and exit openings of the oven. If such adjacent equipment
is not part of the current line layout, Nordson ASYMTEK recommends the use of extensions and/or
shutters or that you take other measures to eliminate the escape of light from the oven. See 4.7 Internal
UV Radiation Shutters Height Adjustment and 4.9 External UV Shutters Adjustment for more information.
Nordson ASYMTEK suggests the measures described above be adopted to minimize the opportunity for
operating personnel to be exposed to harmful light emissions from the oven.
Examples of unintended use of the UV-9 Cure Module are:
• Using in combination with a volatile organic compound (VOC) such as a solvent based
coating
• Using batch mode (non in-line)
• Having a line configuration where operators are subject to direct exposure of unblocked
escaping light, (at the entrance or exit openings of the oven)
• Installing the UV-9 Cure Module without adjacent equipment blocking entrance and exit
openings
• Using incompatible materials
• Making unauthorized modifications
• Removing or bypassing safety guards or interlocks
• Using incompatible or damaged parts
• Using unapproved auxiliary equipment
• Operating equipment in excess of maximum ratings

2.4 Basic Safety Precautions and Practices
Compliance with the following recommended precautions and practices can prevent personal injury or
damage to property during UV-9 Cure Module operation and maintenance.
WARNING! CAUTION!
Failure to comply with any of the safety recommendations could cause serious
injury to the user or damage to the curing system.
2.4.1 Safety of Personnel
If you are entering the workspace of adjacent equipment, either switch the UV-9 off or wear
300 gram cotton gloves and long sleeves or arm covering clothing as well as face and eye
protection (e.g. protective welding goggles).
Do not look directly at the UV lamp.
Do not expose skin or eyes to UV or IR radiation when performing any activity causing
exposure to the lamp(s).
If you must operate in batch mode for maintenance purposes, wear 300 gram cotton gloves
and long sleeves or arm covering clothing as well as face and eye protection (e.g. protective
welding goggles).
Only trained personnel should perform operation, maintenance, service, and troubleshooting
procedures.
There should always be a second person present when performing maintenance on a system
under power.
Locate, identify, and obey all safety warning labels on the UV-9 Cure Module before initial
use. See 2.5 Safety Warning Labels for more information.
Immediately push the red Emergency Stop (E-Stop) button if personnel are in danger of
being injured.
Lock out and tag out power to the UV-9 Cure Module and upstream/downstream machines
before performing any servicing or maintenance. See 2.12 Lockout/Tagout of Electrical
Energy for more information.
Make sure all facility power sources are safely grounded.
Do not wear loose clothing or jewelry and tie back long hair while servicing the conveyor
or other moving parts.
Do not touch the conveyor belts and other moving parts while the UV-9 Cure Module is
operating.
The UV dryer can reach operating temperatures greater than 50 °C (122 °F). The UV source
is cooled by forced air. This forced air must be extracted to the outside of the UV dryer. The
air temperature can reach 80 °C (176 °F) and it is composed of H
2
O (water), O
2
(Oxygen)
and O
3
(ozone). See the material manufacturer’s Material Safety Data Sheet (MSDS) and
local regulation.
• Always wear appropriate personal protective equipment (PPE) as recommended by facility
safety practices and the MSDS.
• Make sure that the main power cable is securely connected before operating the UV-9
Cure Module.
• If in a confined room, ensure adequate and uninterrupted air ventilation, heating, and
cooling to meet environmental stress limits of personnel and the UV-9 Cure Module.
• Where volatile organic compound (VOC) emissions can exceed safe limits, facility
ventilation and filtration systems must be operational.
• Provide adequate space around the curing system to allow for movement of maintenance
and service personnel. Allow space for access doors and service panels to open fully.
• Make sure all facility power sources are safely grounded.
• Routinely inspect all electrical cables for damage.
• Make sure that power cords do not cross a walkway or aisle.
• Before attempting to lift a load, take into consideration facility lifting and transport
precautions.
• Maintain a clean and orderly work area.
NOTE Discomfort from excessive exposure to UV light typically begins
approximately six hours after exposure. A symptom of short term exposure
might be a skin rash or eye irritation, while longer exposure might cause burns.
If eye pain or skin burn is experienced, consult a doctor. Symptoms of exposure
to IR are similar to those of short term UV exposure, and are likely to happen
prior to those caused by UV due to the relative distribution of the lamp.
2.4.2 Material Safety
• Follow MSDS recommendations for the proper handling, cleanup, storage, and disposal of
hazardous materials.
• Know the MSDS recommendations for treatment of injury resulting from exposure to
hazardous materials.
2.4.3 Ultraviolet Radiation
• Ensure that light shields are in place around the UV lamps. See 4.6 Internal UV Radiation
Trap Flap Height Adjustment and 4.7 Internal UV Radiation Shutters Height Adjustment for
details.
• Although the equipment is designed for in-line use with adjacent equipment blocking the
conveyor openings, local regulations outside Europe might allow for manual operation.
During manual operation, wear protective welder’s goggles (with green lenses). Wear
gloves and long-sleeved shirts.
NOTE Discomfort from excessive exposure to UV light typically begins after
approximately six hours of exposure. If you experience eye pain after possible
exposure to UV light, consult a doctor.
