Prior to operation of the unit check the following items carefully: Transport Safety Cushions During transport lamp is protected by foam cushions. As failure to remove these will destroy the lamp, it is also electrically disconnected during transport. Follow the instructions “Changing the Lamp-Module” to remove the foam cushions. Mains Supply Make sure voltage and frequency on the nameplate match with your local mains supply. Connect power cord to a properly grounded AC outlet. UV-Lightguide Insert the flexible LIQUID LIGHTGUIDE with the Ø16mm fitting into the lightguide socket in the front panel of the lightsource. Attention: Shutter will not operate unless lightguide is fully inserted. Treat the lightguide with care, it is an optical instrument. Do not kink or crush it and do not bend it too sharply to avoid light losses. From time to time clean lightguide end faces with a soft tissue and solvent. When using a dual branch LIQUID LIGHTGUIDE the two branches must be positioned vertically above each other in the lightguide socket in the front panel. Only this position ensures maximum radiation output. Insert the lightguide all the way into the socket and rotate it until it snaps into vertical position. For technical reasons the radiated power of the two branches may differ up to a ratio of 40:60 percent. Ventilation Cooling air is sucked through opening at the bottom of the unit, hot air is expelled at the back. Both openings may not be obstructed in order to allow free ventilation. Obstruction of these openings will cause unit to overheat. Vapours of Solvents Vapours of fluorinated or chlorinated hydrocarbon solvents will corrode the lamp and the quartz lenses – even in small concentrations. Avoid these solvents in the vicinity of the unit. If you cannot avoid them, place the unit as high as possible, as vapours are heavier than air. Explosive Surroundings This unit is not meant for operation in explosive surroundings. Protection against UV-Radiation To avoid tissue damage do not expose the unprotected eye or skin to the ultraviolet light. For more information on UV radiation please refer to chapter 6. 4 2. Operation Warming up Turn on the mains supply through the green switch on the front panel. The lamp will ignite and the fan will begin to operate. After a warm-up time of approximately 15 minutes the lamp reaches its full power. Switching off during warm-up can damage the lamp. Every ignition wears the lamp, similar to the cold start of a car engine, we therefore recommend not to switch off the unit if you need it again within the next three hours. Shutter and Timer After pressing the orange starter button the shutter will open for the selected amount of time (selectable from 0.1 to 999.9 seconds) and release the UV radiation; holding the starter button will extend exposure time. If the timer is set to “000.0”, the shutter will open only as long as the orange starter button is pressed; alternatively the timer can be switched off on the rear panel. The footswitch which can be connected to the rear panel has the same function as the orange starter button. For integration into external control systems the footswitch can be replaced by a galvanically isolated closing contact. Switching off The green switch on the front panel will turn off the lamp and the mains supply. Reignition If the unit is switched off, allow the lamp to cool down for at least 10 minutes prior to reignition. Do not attempt reignition earlier as this may damage the lamp. 3. Special Instructions Lamp Life Based on operating intervals of a normal working day UV radiation power of the lamp will drop to approximately 50% after 600 operating hours, and the lampmodule should then be replaced. Repairs and Service Always disconnect power cord before opening up the unit. Do not attempt any repairs other than exchanging the lamp-module (see instructions “Changing the Lamp-Module”). Refer all other repairs to an authorized service facility. 5 4. Changing the Lamp-Module The changing of the lamp-module should be done only after the lamp has completely cooled off. Please proceed as follows (see diagram): • Disconnect the power cord. • Remove the top cover of the unit by unscrewing the two upper screws on the left and right hand side of the unit respectively, disconnect earth wire. Remove the knurled screw on the side of the lamp-module. • Unplug the lamp-module connectors and remove the module carefully by a simultaneous backwards and upwards movement. • Remove the transport safety cushions from the new lamp-module and insert it by vice-versa procedure. • Plug in the connectors of the lamp-module and the earth wire of the top cover and close the cover. 5.

Information on UV Spectra and the different filter options of the Loctite 97032 The ultraviolet spectrum is divided into three sections: UVA 315nm – 380nm UVB 280nm – 315nm UVC 100nm – 280nm UVA is a part of natural sunlight and it’s most visible effect on human tissue is the tan. It’s intensity is easily underestimated, as it is not visible. An overdose of UVA will not cause a UV-erythema (sunburn) but a heat-erythema similar to visible light. UVB is more aggressive than UVA, and also a part of natural sunlight. It has the same negative effects on human tissue as natural sunlight, the most common being the UV-erythema (sunburn). UVC is not generated by the lamp in this unit and not transmitted by the LIQUID LIGHTGUIDE. For safety reasons it should generally be avoided to expose the unprotected eye or skin to the ultraviolet light. For a maximum of operational safety this unit is generally equipped with “UVA + blue” filters which are integrated into the unit. The blue light serves as pilot light. UV epoxies mostly have their maximum efficiency in the UVA. However most epoxies also react to UVB, which means that they cure faster when they are exposed to UVA and UVB. Some epoxies will not cure without UVB and UVB is also helpful in reducing surface stickiness. So from a technical and economical standpoint the “UVA + blue” filter holds back UV energy which can be very useful. On special request this unit is equipped with either “UVB + UVA + blue” filters or with “UVB + UVA + visible” spectrum, the latter meaning it has no filters at all for maximum efficiency. When working with UVB extra precautions must be taken and operating personnel must be completely shielded from the UV radiation. Please check the serial number and radiation spectrum in chapter 7 of this manual to see with which filters your unit has been equipped. Competitive units may have a different spectral output. A comparison of radiation power of different units is only possible if they emit the same spectrum. 7 7.
