ONLY Varian-trained, Varian-qualified, or Varian-approved
Customer Service Representative (CSR) may open panels or
covers, which are retained by screws on the detector. Consult the
manuals or product labels supplied with the PC, monitor and
printer/plotter to determine which parts are operator-accessible.
Operators and other unauthorized personnel are permitted access
ONLY to the lamp sources for replacement. ALWAYS switch off
the detector before changing a lamp.
Good grounding is essential to avoid a potentially serious electric
shock hazard. Ensure that there is an integral ground connection
between the metal base of the detector and the 3 pin earth-
grounded receptacle.
Note that the safety classification is given as Class 1 (EN 61010-
1). The PC must comply with IEC 60950.
Application of the wrong supply voltage can create a fire hazard
and a potentially serious shock hazard and could seriously
damage the ProStar 325 system and any attached ancillary
equipment.
Replace blown fuses with fuses of the size and rating as
stipulated in the text adjacent to the fuse holder at the rear of the
detector or, as specified in the manual.
Never use power cords with faulty or frayed insulation.
1.6.2 Lamp source
The UV and Vis lamps are enclosed in self-contained modules.
Both operate at high temperatures and touching either of these
may result in burns. Before replacing a lamp that has been lit,
switch the detector off and ensure that you either wait for the
lamp to cool, or protect your fingers from burns. The UV lamp
module operates at high voltages.
When operating, these lamp sources emit high intensity UV and
Visible light that can cause serious damage to eyes. To avoid eye
damage, never operate a lamp outside the detector.
NEVER look directly at the UV source lamp. ALWAYS wear safety glasses
manufactured to an approved standard and which are certified or otherwise warranted to
protect the eyes from UV radiation when the UV lamp is operating.
1.6.3 Panels and covers
Only the panel that provides access to the lamp compartments
and flowcell may be removed by the operator. All other panels or
covers that are retained by screws on the detector may be opened
only by Varian-trained, Varian-qualified or Varian-approved
