Care and cleaning

The unit has to be switched off when carrying out
any maintenance work, e.g. exchange of
lamps, cleaning and emptying of the tank.
Turn the main switch to position "0" and
pull mains plug. Secure against reconnec-
tion to the mains. The following work should
be carried out at regular intervals in order
to ensure correct functioning of the unit.
10.1 Cleaning of quartz- and
glass components
According to the cleanliness of the laboratory air
and the maintenance condition of the unit, the fil-
ters should be cleaned in regular intervals or when
necessary, in order to prevent an unacceptable de-
crease of the irradiance. Finger prints on the filter
surface should be avoided or carefully removed with
a soft cloth.
The Suprax outer cylinder made of special UV
glass as well as the window glass filter can be
cleaned in a 20% citric acid solution. Cleaning
efficiency is increased if it's warm.
The IR filters and the UV filter glass are sensiti-
ve to moisture. It is generally sufficient to clean them
with a duster. If absolutely necessary, they may also
be cleaned with an organic and alcali-free cleaning
agent.
The XENOCHROME filters can be cleaned with
commercially available alcohol or spirit, taking care
that any damage to the surface is avoided.
The XENOSENSIV filters are sensitive to
scratching.
10.2

Cleaning the test chamber

After prolonged periods of operation, the test cham-
ber may show traces of dirt and contamination de-
rived from the samples, from the air, or from the
water. We recommend to keep the entire test com-
partment clean in order to maintain uniform sur-
face reflection.
Use a liquid cleaning agent which does not contain
any chlorine compounds and is suitable for special
steel. Carefully rinse the surfaces with ultra puri-
fied water after using the agent to ensure that the

distilled water used later in the system does not
become contaminated.
The procedure to clean the test chamber is descri-
bed in chapter 4.1.2.
10.3

Cleaning the water tank

According to the degree of contamination (depen-
ding on laboratory conditions), we recommend fre-
quent cleaning of the water tank, in order to pre-
vent pollution of the pipe system and test chamber.
Therefore empty the tank and remove the tank from
the system.
10.4 Changing the air filter
On the right-hand side and the rear panel of the
unit air filters (filter type EU4) are fixed on wire
meshes. They can be withdrawn by pulling them
backwards. Please ensure when replacing the filter
that the soft side faces outwards and that the edges
seal tightly. The regenerating filter pad consists of
polyamide fibres bonded with synthetic resin. At a
normal degree of pollution, it is generally sufficient
to rinse the removed filter pad in luke-warm water
to which a small amount of fine detergent was
added. Where more severe contamination occurs,
the pad can be beaten, vacuumed or blown through
using a gentle jet of compressed air.
We recommend to clean the filters every 6 months,
respectively when necessary in case of
unfavourable environmental conditions.
Insert a new filter pad after having cleaned
it twice.
