Unpacking, Positioning and Installation
•Inspect the instrument for any signs of damage caused in transit. If any damage is
discovered, inform your supplier immediately. Check the position of the metal lamp
bracket inside the lamp access area.
•Ensure your proposed installation site conforms to the environmental conditions for safe
operation:
Indoor use only
Temperature 5°C to 35°C. Note that if you use the instrument in a room subject to
extremes of temperature change during the day, it may be necessary to recalibrate (by
switching off and then on again) once thermal equilibrium has been established (2-3
hours).
Maximum relative humidity of 80 % up to 31°C decreasing linearly to 50 % at 40°C
•The instrument must be placed on a hard, flat bench or table that can take its weight (<2
kg) such that air is allowed to circulate freely around the instrument.
•This equipment must be connected to the power supply with the power cord supplied. It
can be used on 90 - 240V supplies.
•Switch on the instrument via the display after it has been plugged in. The instrument
performs a series of self-diagnostic checks for lamp performance, wavelength calibration
and diode array pixels; press F2 to proceed.
If the instrument has just been unpacked or has been stored in a cold environment, it
should be allowed to come to thermal equilibrium for 2-3 hours in the laboratory
before switching on to prevent calibration failure as a result of internal condensation.
•The cell holder supplied with the instrument accepts standard 10mm pathlength glass or
plastic cells (adapters are available to convert it to accept 10, 12 and 16mm diameter test
tubes). It can be removed for cleaning if spillages occur by undoing the screws that hold
it or it can be flushed through with water in situ.
If this equipment is used in a manner not specified or in environmental conditions not
appropriate for safe operation, the protection provided by the equipment may be impaired and
instrument warranty withdrawn.
Essential Safety Notes
There are a number of warning labels and symbols on your instrument. These are
there to inform you where potential danger exists or particular caution is required.
Before commencing installation, please take time to familiarise yourself with these
symbols and their meaning.
Caution (refer to accompanying documents).
Background colour yellow, symbol and outline black.
