ARRANTY

General

Elcon Instruments certifies that all the instruments of their manufacture are immune from defects or loss of es-
sential quality, and whenever they are apparatus, Elcon also guarantees proper operation. The duration of the war-
ranty period is indicated in the order confirmation and starts from the date of delivery or on site test (if required).
Unless otherwise specified the warranty is of 12 months, from delivery date.

The action due to the customer for vices, defects, or loss of quality is subject to the terms of articles 1495,1497
C.C. (Italian Civil Code). The denunciation of the, defect or quality loss must be made by the customer by registe-
red mail, telex, fax, or equivalent written form to be sent to the main office of Elcon Instruments.

Limits - burdens - obligations

a)  The warranty is limited to repairing and substitution, FOB Elcon Instruments factory, of the useless parts, for a

confirmed defect of materials and/or workmanship, free of charge, and the remaining, shipping, dismounting and
mounting expenses (operations that in any case must be done in accordance with the supplier), at the custo-
mer’s charge. In no case Elcon Instruments will be held responsible for expenses, for loss of profit and/or dama-
ge, direct or indirect, that can be incurred by the customer due to a fault or defect of the material.

b) The warranty ends for instruments or materials damaged by:

- shipment
- storage non conforming to the instruction manual specifications
- incorrect installation
- loss of adequate protection for the type of installation (mechanical, climatic, etc.)
- incorrect application of power supply voltage
- erroneous wiring of the power supply line (applied on input or output measuring circuits)

c)  The warranty ends for instruments or materials if repaired, modified, or simply tampered with, even if only in

part, by personnel not authorised by Elcon Instruments and also ends if used in improper way and/or not confor-
ming with the given instructions. 

d)  The warranty is valid only if payment has been received from the customer in a timely fashion, as per the origi-

nal agreement; otherwise it is void.

e)  All parts that are subject to normal wear and inevitable deterioration are excluded from this warranty.

f)  In case of having to return the instrument to one of the Elcon Instruments authorised labs for repair, the custo-

mer  shall  obtain  a  written  authorisation  with  shipping  instructions  from  Elcon  Instruments.
Shipment expenses, all the concerned burdens, and the risk of loss or damage of the returned instrument are
exclusively born by the customer.

The same rules apply also when the instrument needs to be replaced.

g)  During the warranty period, the customer will allow any personnel appointed by Elcon Instruments execute con-

trol of the instruments and materials.

h)  The customer cannot require cancellation of the contract in reason of vices or defects, but only their elimination

or, when they cannot be repaired, the replacement of the instruments, if available on the market. In case the
replacement is for any reason impossible, Elcon Instruments has the faculty to offer instruments of the same or
equivalent type, quality and efficiency, suitable to the same use.

If the customer refuses such offer without justified motivation he is entitled to reimbursement of the money

already paid or a refund of the real incurred expenses.

i)  For items sub-supplied by Elcon Instruments the standard warranty terms as given by the original manufacturer

are applicable.

j)  The warranty must be considered for material repaired, substituted on ex works basis.

Such warranty replaces and supersedes any other declared or implicit warranty
