Thermal hazards
The following safety precautions must be
observed when operating the UVAHAND
250:
•Never touch the filter during operation.
Danger
There is an acute danger of fire and burns caused by the high tem-
perature of the filter during operation (up to 200 °C)!
•Protective clothing (protective gloves, UV
protection goggles) must be worn when
working within the radiation field.
•There must always be a distance of at
least 1m between the equipment and
flammable objects.
•If the reflector is temporarily covered with
a screen, leave a gap of 3 to 5 cm be-
tween the screen and the filter to prevent
a build-up of heat.
•The UV lamp must not be used inside
explosion-protected areas.
Danger
The UV lamp must not be used in explosion-protected areas because
of the high temperature it reaches (1000 °C). There is an acute dan-
ger of explosion!
•Never lay the lamp unit filter down while
the equipment is switched on.
This would trigger the thermal fuse and
cause damage to temperature-sensitive
and combustible surfaces.

UV radiation (UVC and UVB).
For this reason, the UVAHAND 250 must only be operated with an intact filter.
Danger
If not used properly, UV radiation can damage the skin and eyes!
It can cause severe sunburn or inflammation of the retina and con-
junctiva.
The following instructions must be observed
when working with the equipment:
•Never look directly into the lamp when it
is switched on.
•The UVAHAND 250 must not be oper-
ated without the filter.
•The lamp must be positioned in such a
way that no-one is exposed to direct ra-
diation.
•The filter must be inspected regularly for
signs of damage.
•The equipment must not be operated
unless the filter is intact.
•When working within the radiation field,
always wear the corresponding protective
clothing and UV goggles.
•When working without protective clothing,
the UV radiation must be completely
shielded so that personnel is not ex-
posed.
Note
Protective articles are listed in the chapter ‘Order data for equipment,
spare parts and accessories’.
Caution
UV radiation can cause damage to electronic components!
If EPROMs are used in the vicinity of the UVAHAND 250, they must
be protected against UV radiation.

UV radiation accelerates the aging process of materials!
Surfaces and objects sensitive to UV radiation must be protected
before operation.
Danger caused
by gases and
radiation

User’s Manual 13
Danger caused by gas
Chemical fumes can be released when radi-
ating materials with the UVAHAND 250.
•Observe the safety data sheets for the
materials to be radiated.
•Where necessary, breathing equipment is
to be worn, and it must be ensured that
the work area is adequately ventilated.
•At the start of operation, measure the
level of radiation in the atmosphere. If the
level is too high, a ventilation and suction
unit must be installed.
•UV rays encourage the production of
ozone. For this reason, it is essential to
ensure that the workroom is well
ventilated.
Danger
The lamp contains mercury!
If it breaks when it gets hot or during operation, mercury vapour is
released.
Everyone present must leave the room immediately. The room must
be thoroughly ventilated.

6 Setting-up, commissioning and operation
General information
•When setting up the equipment, ensure
that there are no fingerprints on the re-
flector, the lamp or the filter.
•Never touch the reflector.
•Only handle the UV lamp by its ceramic
bases or with a clean cloth.
•If it is necessary to clean the reflector, the
lamp and the filter, do so when they are
cold, and always use a clean cloth and
alcohol.
Note
Marks on the UV lamp or the reflector (e.g. fingerprints) will be burnt
on when the lamp is put into operation. They reduce the service life
and the performance of the UV lamp.
•Check the air inlets and outlets in the
casing before switching the equipment
on.
There must be no foreign bodies covering
or blocking the apertures.
•When the hand-held lamps are switched
on, never deposit them on temperature-
sensitive or combustible surfaces with the
filter facing downwards.
•If the reflector is to be covered with a
screen for any period of time during op-
eration, ensure that there is a gap of be-
tween 3 and 5 cm between the screen
and the filter.
This will prevent the build-up of heat,
which can lead to the destruction of the
filter. While the spacer bar is fitted, this
gap is automatically given, so please do
not remove this bar.
Danger
Ensure that the cooling is sufficient when setting up the UVAHAND
250. There is acute danger of fire if the equipment is not sufficiently
cooled!
Neither the ambient temperature nor the cooling air temperature may
exceed 45 °C.
•The equipment must be protected against
chemical fumes.
•Only operate the UVAHAND 250 in dry
