6 Maintenance
6.1 General Information
The
UVD 170S/340S
is constructed only from the highest quality components, thus keeping
maintenance requirements to a minimum. In general, the unit should be kept clean. The
painted surfaces are resistant to solvents as well as weak acid or alkaline solutions. If solvents
or other liquids should be spilled on the surface, these should be cleaned off immediately,
using a lint-free cloth or tissue (avoid rubbing).
The following sections describe all maintenance work which can be carried out by the user.
Any other service or maintenance work should be carried out only by a qualified Dionex
personnel.
In the event that the
UVD 170S/340S
should require shipment for the purpose of service, this
should be only in the original packing. If no original packing is available, this can be acquired
from Dionex or your local Dionex representative.
Please note:
The warranty coverage shall become invalid in any case identified as
resulting from inappropriate use, service or the implementation of non-
specified spare parts. Similarly, the warranty coverage shall be
invalidated in the event of inappropriate shipment, packaging or failure to
remove aggressive or damaging solvent residues.
All user serviceable parts (i.e. lamp and flow cell) are accessible via a removable panel,
located on the left side of the unit (
→
fig. 6). To open, press in and turn the knurled screw 90
o
anti-clockwise. The panel may now be opened and removed. The lamp and flow cell are now
clearly visible.
Warning:
During operation, the lamp becomes extremely hot and remains so for
some time after the unit is switched off. Therefore, to avoid possible
injury, always allow sufficient time for lamp cooling before attempting
any maintenance.
