1.2 Safety instructions for the customer
General:
• The electrical connection of the equipment has to be made by an electric specialist.
• Please note the special safety hints in the chapters "unit set-up" and "maintenance".
• Instruct the operating personnel with the help of this operating manual in the operation, function
and care of the unit. The unit may only be operated by instructed personnel. The operating
manual should be kept close to the unit.
• Inform the operating staff about accident prevention regulations regularly.
• For work at and with the unit the user needs instructions in his mother language based on the
operating manual (FRG: UVV VBG1 § 7 (2)).
• Before starting the unit ensure that the necessary requirements for a failurefree operation of the
unit are given. Observe the installation requirements in chapter 3.2 of this manual as well as valid
national laws, regulations and guiding principles.
Intended areas of application:
• The ALPHA and HIGH ENERGY units are designed for research, development and test laborato-
ries
• The ALPHA and HIGH ENERGY units shall only be used for the exposure and weathering of
materials in the intended areas of application.
• Inflammable or explosive materials must not be inserted into the unit. Do not insert materials
which despite their application as directed release toxical substances.
• Handling and usage contrary to the intended areas of application described in this operating manual
can present unforeseeable risk and should be avoided.
Maintenance and cleaning:
• The lateral two-leaf doors must only be opened by Xenotest personnel, an autorised customer
service or an electrical specialist.
• After one year it is necessary to subject the unit - especially the safety components - to regular
inspections.
• Mounting, extensions, replacements and repair work may only be carried out by Xenotest or an
authorised customer service engineer.
• The safety of the unit is only given, when the necessary maintenance and repair work is kept
within time and carried out by Xenotest or an authorised customer service engineer.

1.3 Safety instructions for the operator
• The unit must be operated by instructed and authorised personnel only.
• Overheating and damage of the unit and the samples may occur, when the filters are not inser-
ted. Always insert the filters!
• Disconnect the unit from the mains, pull mains plug and secure against replugging, when fitting
the filter system, the lamp and the lantern as well as when carrying out care and cleaning work.
• Lamps, specimens, specimen holders and sensors heat up considerably during the weathering
tests. Protective gloves must therefore be worn when removing them to prevent injury to your
hands. This applies in particular to high temperature tests.
• When removing the lamp exhaust air hose while the unit is running UV radiation may emerge and
may cause irritation of the retina and the scin. Remove the lamp exhaust air hose only when the
unit is switched off.
• Please observe the special safety hints in the text of the chapters "unit description", "start-up",
"function", "setting-up tests", "care and cleaning".
The unit complies with the safety standards of:
• DIN VDE 0411 part 1 / 03.94
Measuring, Regulating, Controlling
Safety requirements for electric motor-operated measuring, regulating, controlling and
laboratory units.
• DIN VDE 0711 part 1 / 09.91
Lamps
• DIN VDE 0875 part 14 / 09.91
Limits and methods of measurement of radio disturbance characteristics of electric motor-
operated and thermal appliances for household and similar purposes, electric tools and similar
electric apparatus. (EN 55 014)
• DIN VDE 0871 part 11/09.87
Limits of radio disturbance and measuring methods for industrial, scientific and medical high-
frequency apparatus (EN 55 011).

3.2 Space requirements
3.2.1 Laboratory
• Set up the unit in a air-conditioned and air-
filtered laboratory at 18°C - 25°C and a rela-
tive air humidity of max. 50%.
• Supply an amount of approx. 300m3 air per
hour via an air filter to the laboratory (filter
type EU 4).
• Keep the laboratory free of dust.
3.2.2 Exhaust air
• The exhaust hoses for the lamp and the test
chamber must be made of flexible
heatresistant material, as the temperatures
of the exhaust air may reach up to a max. of
120°C.
• The max. length of the exhaust hose is
limited to 3m including the option of two 90
degree bends.
• In case of longer exhaust air ducts or with
more than two 90 degree bends an external
blower is needed.
3.2.3 Electrical supply
The electrical connection to the mains has
to be made by an electrical specialist. The
unit is designed for a mains supply of
230V +/- 10%. Different voltages are
obtainable by fitting mains trans-formers.
Connection is ensured by (1,N,PE or 2,
PE), CEE (32A, 3pol.,6h).
• For the electrical supply observe UVV
VGB 4.
• Mains conditions have to agree with the
data on the name plate.
• Observe VDE- and technical connection
regulations of the energy supply compa-
nies.

3.2.4 Water quality
The water must be of high-grade purity
to prevent deposits.
The use of ion exchange cartridges alo-
ne is not sufficient.
Regarding the water purity we refer to the mini-
mum requirements of some important standards,
such as DIN 53387 „Artifical light and weather fast-
ness of plastics“:
1. Electrical conductivy: < 5 µS/cm
2. PH value: 6-8
3. content of solid bodies < 1 ppm measured
as silicon dioxide.
3.2.5 Water supply
To ensure the functioning of the water
circuit and the humidification system,
the apparatus must be aligned by
means of its height adjustable feet.
By supply line:
fill the water tank (fig.9) with a pressure-resistant
hose to the water inlet of the tank (inner diameter
13mm, 3bar pressure).
without supply line:
fill the water tank manually.

Open the test chamber by pressing the door lok-
king. A program is interrupted when the test cham-
ber door is opened while a unit is running.
Are located in the test chamber :
- Chosen outer cylinder (1),
- Xenon lamp (2),
- Filter lantern (3),
- 11 sample holders (4),
- sample holder mountings (5).
Function:
The samples rotate around the lamp and filter lan-
tern. In turning mode operation the samples are
turned by 180° per caroussell revolution.
Ventilation:
Test chamber and Xenon lamp are supplied by two
separate air flows.A uniform air ventilation is achie-
ved by an appropriate air flow (fig. 10 ventilation
scheme).
Temperature, humidification and rain:
Air is taken from the test chamber by an air ex-
haust hose (6), warmed up by a heating system
and humidified in the humidifier, and then sent back
to the test chamber by an air supply hose (7).
The maximum chamber humidity can be adjusted
up to 95% r. h. depending on the preset tempera-
ture.
The rain bar (8) mounted in the test chamber is
used to spray ultra-pure water in cyclical intervals
and without any pressure on to the specimens.
Sensors:
At sample level a XENOSENSIV sensor (9) for
measuring the irradiance in the range between
300-400nm and the black standard temperature in
the surface temperature range up to 130°C can
be fitted to the test chamber by means of an ad-
apter (10) (fig. 31). The sensor is connected to
the program control via a connection socket (11).
If no sensor is used the end plug must be fitted to
the connection socket (fig. 36).
A sensor to measure the test chamber tempe-
rature and rel. humidity (12) is mounted in the
upper rear of the test chamber. The sensors com-
bined with the program control guarantee control
of constant setting values.
Contrast to ALPHA:
Are locared in the test chamber:
- arc-shaped Xenon lamp (1)
Ventilation:
A uniform air ventilation of the sample area is achie-
ved by an air conduction plate (2) (fig. 11 venti-
lation scheme).

Data output:
Data of stored programs as well as current measu-
ring values can be printed-out by a thermoprinter
(2). The interface (3) on the right-hand side of the
main switch provides for the data output and ex-
ternal computer control.

Ventilation:
The air intake for the lamp cooling (19) passes
through a filter pad in the equipment door.
The main switch (1) (fig.7) is located on the upper
left of the unit. Use this switch to disconnect the
unit from the mains in case of trouble.
The lateral two-leaf doors of the unit
must only be opened by XENOTEST, or
an authorized customer service engineer
or an electrical specialist.
Contact with live parts of a unit connec-
ted to the mains may involve electrical
shock.
