Dimensions and Weight
Select the laboratory bench space before the system arrives. Make sure the
area is clean, clear, and level. Pay special attention to the total height
requirements. Avoid bench space with overhanging shelves. See Table 2.
The instrument needs space for proper convection of heat and ventilation.
Allow at least 25 cm (10 in) clearance between back of the instrument
and wall to dissipate hot air and allow for routine maintenance.
