Warranty
All Airedale products or parts (non consumable) supplied for installation within the UK mainland and commissioned by
an Airedale engineer, carry a full Parts & Labour warranty for a period of 12 months from the date of commissioning or
18 months from the date of despatch, whichever is the sooner.
Parts or Equipment supplied by Airedale for installation within the UK or for Export that are properly commissioned in
accordance with Airedale standards and specifi cation, not commissioned by an Airedale engineer; carry a 12 month
warranty on non consumable Parts only from the date of commissioning or 18 months from the date of despatch,
whichever is the sooner.
Parts or equipment installed or commissioned not to acceptable Airedale standards or specifi cation invalidate all
warranty.
Warranty is only valid in the event that
In the period between delivery and commissioning the equipment:
•
is properly protected & serviced as per the Airedale installation & maintenance manual provided
•
where applicable the glycol content is maintained to the correct level.
In the event of a problem being reported and once warranty is confi rmed* as valid under the given installation and
operating conditions, the Company will provide the appropriate warranty coverage (as detailed above) attributable to the
rectifi cation of any affected Airedale equipment supplied (excluding costs for any specialist access or lifting equipment
that must be ordered by the customer).
*Once warranty is confi rmed, maintenance must be continued to validate the warranty period.
Any spare part supplied by Airedale under warranty shall be warranted for the unexpired period of the warranty or 3
months from delivery, whichever period is the longer. To be read in conjunction with the Airedale Conditions of Sale -
Warranty and Warranty Procedure, available upon request.
Procedure
When a component part fails, a replacement part should be obtained through our Spares department. If the part is
considered to be under warranty, the following details are required to process this requirement. Full description of part
required, including Airedale’s part number, if known. The original equipment serial number. An appropriate purchase
order number.
A spares order will be raised under our warranty system and the replacement part will be despatched, usually within 24
hours should they be in stock. When replaced, the faulty part must be returned to Airedale with a suitably completed and
securely attached “Faulty Component Return” (FCR) tag. FCR tags are available from Airedale and supplied with each
Warranty order.
On receipt of the faulty part, suitably tagged, Airedale will pass to its Warranty department, where it will be fully
inspected and tested in order to identify the reason for failure, identifying at the same time whether warranty is justifi ed
or not.
On completion of the investigation of the returned part, a full “Report on Goods Returned” will be issued. On occasion
the release of this complete report may be delayed as component manufacturers become involved in the investigation.
When warranty is allowed, a credit against the Warranty invoice will be raised. Should warranty be refused the Warranty
invoice becomes payable on normal terms.
Exclusions
Warranty may be refused for the following reasons.
• Misapplication of product or component
• Incorrect site installation
• Incomplete commissioning documentation
• Inadequate site installation
• Inadequate site maintenance
• Damage caused by mishandling
• Replaced part being returned damaged without explanation
• Unnecessary delays incurred in return of defective component
Returns analysis
All faulty components returned under warranty are analysed on a monthly basis as a means of verifying component and
product reliability as well as supplier performance. It is important that all component failures are reported correctly.
