HEDSON 715423 IRT ETL UV Spotcure2

IMPORTANT SAFETY INSTRUCTIONS

Summary of results from RISE, Research Institutes of Sweden AB

Depending on the distance from the UV curing device, the limit value according to AFS 2009:7 index b. (UVA eye) for one working day (8 h) is reached after one or a few minutes at close distances (~0.5 m). At longer distances than about 4 m, the acceptable exposure time is an hour or more.

To reduce risk of injury or property damage from UV radiation, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this curing equipment follows these safety instructions as well.

• Always wear eye protection. Failure to this may result in long term injury to the eyes.
• Wear protective clothing. Hands, face and other parts of the body shall not be exposed to heat and radiation. Do not stay in front of the lamp cassettes during curing without safety equipment.
• If a person works around UV radiation while on medications, the medication should be checked to see if it would make the person more photosensitive.
• Do not look directly at the light source.
• Professional commercial indoor use in a dedicated, isolated, or restricted area, accessed only by qualified professional operators.
• These products are intended only for use in a restricted access area, or an area which incorporates suitable site protection to prevent unintended exposure of untrained or unqualified persons to ultraviolet radiation. It is the responsibility of the designated parties at the final installation site to confirm that proper installation, training, and control means have been implemented.

WARNING! GROUNDING INSTRUCTIONS
This equipment must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current toreduce risk of shock. This equipment is equipped with a cord having an equipment grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance wiith all local codes and ordinances.

WARNING
Improper connection of the equipment-grounding conductor is able to result in a risk of shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the equipment is properly grounded. Do not modify the plug provided with the equipment. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Introduction

Intended use of the product

This product serves exclusively to accelerate the curing of UV putty, filler, base and clear coats. The product must not be used for other purposes than the described curing processes. The maximum ambient temperature during operation should not exceed 40°C. The UV LED (Ultraviolet Light Emitting Diodes) equipment is available in wavelength 395 nm. Do not use the product in spray booths or within a distance of 5 m from other solvent based spraying activities in order to avoid explosion risks. Its site of use is the preparation area and finishing area. Within the automotive industry and vehicle repair sectors, it is used to cure small and medium sized areas before polishing.

UV curing

The ultraviolet light spectrum generated by a UV LED interacts with special coating chemistries to produce a high-quality, durable curing. In many applications, UV curing can achieve a faster curing and therefore also at a lower total cost. As the UV coat contains less solvent than conventional paint, the IRT UV SpotCure2 has less environmentally impact.

As LEDs have a narrow wavelength band, it is important to find the optimal wavelength for each UV putty, filler, base- and clear coat. Please read data sheets and discuss with the paint suppliers which wavelength is suitable for your particular product. Most importantly to achieve a good and fast curing result there must be enough UV-A intensity. IRT UV radiation has an outstanding intensity to achieve the best curing result.

Unique benefits of UV cured coating

• Reduced amount of solvent
• Fast curing time
• Low-temperature processing

Operation and training

Read all instructions before using IRT UV SpotCure2.

Before every usage, check that:

• Glass is clean and free from over spray, which decreases the intensity.
• Fan is running during operation.
• UV LEDs light up.
• Check the cable for any signs of damage, such as cracking and tears. If the cable is damaged by wear or tear, it must be replaced before use.
• These products are intended only for use in a restricted access area, or an area which incorporates suitable site protection to prevent unintended exposure of untrained or unqualified persons to ultraviolet radiation. It is the responsibility of the designated parties at the final installation site to confirm that proper installation, training, and control means have been implemented.
