1. 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.

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.

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.

6. 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.
