INSTALLATION OF ARL 3460 METALS ANALYSER 

 

The  actual  installation  is  carried  out  by  the  factory  service  engineer  or  by  local  ARL 
representative's engineer. The service engineer will perform the following tasks: 
 

·

  Check that the delivery conforms to the contract and the delivery packing slip. 

 

·

  Unload the instrument from its transport pallet. 

·

  Open  the  instrument  before  power  up,  so  as  to  determine  if  the  transport  has  caused  any 

internal damage that is not visible from outside. 

·

  Check  that  the  laboratory  and  the  connections  provided  for  the instrument that customer has 

prepared meet the requirements (in chapters 2 to 5 in the pre-installation manual). 

·

  Install and connect the peripherals (computer, printer, etc.) to the instrument. 

·

  Start up the instrument. 

·

  Carry out some typical operations that prove that the instrument is operating correctly. 

·

  Check out (if applicable) the factory calibrated programs with certified standards samples (to be 

provided by the end use) and instruct the customer how to use those programs. 

·

  Give  the  customer  a  basic  training  on  start  up  and  routine  maintenance  of  the  instrument 

(checks, precautions, changing Consumables). The customer will also be given an introduction 
to the normal use of the software. This basic teaching should not exceed one day. 

 

Notes 

Sample  preparation,  analytical  assistance,  analytical  calibrations,  extended  software 
teaching,  teaching  the  maintenance  personnel  (troubleshooting)  as  well  as  other 
services,  if  they  are  not  included  in  the  contract,  are  additional  jobs  outside 
installation.  These  will  be  carried  out  after  the  instrument  has  been  accepted.  The 
local tariff will be applied and our local representative can send you an offer. 

 

It should be noted that reading the documentation delivered will allow the customer to 
deal with any problems, or questions concerning the above. 

 

ARL also offers regular training courses at our premises. Our local representative can 
also gives the necessary information. 

 
 

End of installation

 

At the end of the installation, the service engineer will write an end of installation protocol, as well 
as a technical report on the installation. 
The guarantee covers the instrument according to the terms of the contract. 
Please,  do  not  hesitate  to  call  the  ARL  representative  if  you  require  any  assistance.  The 
instrument  has  a  model  code  (name  of  the  instrument),  as  well  as  a  serial  number.  These 
indications are on a label behind the instrument. They are also written at the end of the installation 
protocol. Kindly quote these as well as your company's name in all correspondence. This will help 
us to give you an efficient service.
