1.7.2 Service policy
In the normal course of field servicing, it is Varian’s policy to
troubleshoot and repair to a modular level at the detector’s
location.
Software diagnostic routines are available to aid in fault
isolation. These are to be used in conjunction with conventional
test equipment to effect on-site repairs.
In situations where minimizing downtime is the prime
consideration board or module exchange should be considered,
but only after preliminary attempts to repair have proven
unsuccessful. Component level repair should not be attempted
outside a designated service repair centre. Electronic assemblies
such as the source lamp module and electronic boards with
surface mount components are not field repairable.
1.7.3 Spare parts policy
Operational spare parts for all Varian detectors and major
accessories will be held in stock for a period of five years after
shipment of the final production unit. Spare parts may be
provided after this five-year period, but only on an “as available”
basis. Operational spare parts are defined as those individual
electrical or mechanical parts that are susceptible to failure
through fair wear-and-tear during their normal operation.
Examples include resistors, inductors, capacitors, semi-conductor
devices, relays, lamps, temperature probes, detectors elements,
motors, wiring board assemblies and the like.
General hardware (for example, sheet metal parts, structural
members, assemblies and castings) will normally outlast the
useful life of the detector and therefore will only be supplied on
an availability basis after the final production unit is
manufactured.
Proprietary items and components that are unique to the Varian
equipment should be sourced from the Varian Service Centre.
Other components may be sourced locally unless otherwise
specified in this manual.
1.7.4 Warranty
All Varian products are warranted against defects in materials
and workmanship, but not against consequential damages. Full
details relating to the terms of warranty are available from any
Varian Sales and Service Office or Agency. No other warranty is
expressed or implied. Consumable items such as (but not limited
to) light sources, temperature probes and other glassware items
are subject to a limited or pro-rated warranty. The Varian
warranty provides for specific legal rights. There may also be
other rights that vary from country to country, or region to
region.
The warranty applies only to the installed Varian equipment, and
cannot be extended to cover the associated miscellaneous
