4PRECAUTIONS OF USE
➢Always make sure that the instrument is connected on the good voltage.
(24VDC +/-0.5VDC 3A or Between 100 –240V 50-60Hz with External Power supply option)
➢Always disconnect the instrument mains power plug before starting any work inside the
instrument.
➢When dangerous substances for health and environment are used, the laboratory or site
rules, where the instrument is installed must be followed.
➢Take all the necessary precautions, during the use the instrument, to protect the operator
from eventual liquids leaks or spills or possible radiations (protective gloves, anti-UV
radiation glasses , protected clothes, etc)
.Keep the sample and cuvette area clean (no liquids or spills).
➢The XENON lamp used in this unit emits UV radiation and must be never touched or
dismounted outside expert people.
➢Install the instrument in a ventilated area because of ambient temperature limits (see
details) for a correct measurement working.
➢All operations made inside the instrument, must be done by AQUALABO or by
AQUALABO’s authorized technicians.
➢Use of the spectrophotometer without danger
If it is necessary to suppose that it is not possible any more to use the
spectrophotometer without danger, it is necessary to put it out of service and to protect
it from involuntary starting up again.
Use without danger will not be possible when the spectrophotometer
•suffered damage during transportation.
•was stored under inadequate conditions for one relatively long period
•present some visible damages.
•does not function any more as described in the user’s manual.
In case of doubt, consult the spectrophotometer supplier.

5.3 FLUIDS CONNECTION (SAMPLE & AIR PRESSURE)
. Fig. 5 Fluids connection drawing
Output tube (Flowing case) is going towards the waste.
Tube coming from electro valve labeled R is going to rinse solution tank
Tube coming from electro valve labeled B is going to blank tank
Tube coming from electro valve labeled S1 is going to sample 1 inlet.
Tube coming from electro valve labeled S2 is going to sample 2 inlet.
Tube coming from electro valve labeled S3 is going to sample 3 inlet.
Tube coming from electro valve labeled S4 is going to sample 4 inlet.
Clean air pressure optional port allow customer to inject pressured air to avoid any
contamination from outside in case of hard environment use. Clean air, means air without
any dust, humidity and oil vapor from outside air compressor. Maximum allowed air pressure
is 0.5bar !

5.4 SAMPLE INLET
5.4.1 PERISTALTIC PUMP RATE OF FLOW
Around 13 liters per hour
Around 220 ml per 60 seconds.
Theoretic volume = 0.019 liter per tube length meter (tube internal diameter: 5 mm).
5.4.2 SAMPLE CHARACTERISTICS
Generally the sample does not need to be prepared before the measuring.
NOTE 1
Nevertheless, in certain conditions, it must be cooled or warmed to avoid the condensation on
the measure flow through cuvette.
Minimum temperature =10°C Maximum temperature = 40°C
NOTE 2
With the installed tubes, it is advised against passing samples containing concentrated solvents,
oils, concentrated acids and concentrated NaOH.
5.4.3 TAKING SAMPLE CONSTRAINTS
The peristaltic pump can bring a sample from a distance of 5 meters maximum and a depth of 2 meters
maximum (see drawing under).
