Valve Failure Issue Update

DAUK reference - E2010342-2

Dear Sir/Madam,

We would like to thank you for continuing to purchase our products. Your custom is valuable to us and we
appreciate your ongoing business and support.

During August, we regrettably had to inform you about a possible SAFETY RISK involving the gas stop valves on several split outdoor units sold in June and July 2020. When communicating this to you, we asked you to return these specific units for a replacement. At the same time we received requests for you to continue with a limited number of installation by taking extra precautions. For these units where a replacement was not possible and commissioning was necessary - the maximum valve opening needed to be limited to 10 complete rotations of 360°.

As a reminder these were serial numbers in scope for the units sold in June and July 2020. All your subsequent purchases and our current stock is not in scope.

For your installations in scope that were commissioned – Daikin has developed a resolution to this issue which will eliminate any future safety risk once implemented. This involves attaching a special valve cap over the current valve in a secure manner. We ask you to carry out this countermeasure following receipt of a pack containing all required parts and tools as well as a labour allowance to be paid in  advance.

2. What will be provided for you to carry out the countermeasure

A bag containing the following items will be provided:
• special valve cap
• glue loctite 270
• plastic cover
• 2 notification tags with pictograms
• hexagonal wrench
• manual

These items will enable the special valve cap to be secured. A procedure for carrying out the countermeasure will also be provided to ensure that the operation is carried out in the correct manner.

3. Compliance record of activity carried out

A pack containing the special valve cap and Tools will be dispatched. Please see attached list of the units that were supplied to you. A labour allowance, credit note as part of our fuss free Warranty, for £90 per unit to be repaired will also be sent separately.

The repair must be carried out as soon as practically possible with the last repair completed no later than 3 months. (End of February 2021)

To ensure our mutual auditing needs, we have created a central database for you to record when the repairs have been completed- please record your repair details on the following link – https://daikin.formstack.com/forms/valve_failure_repair_check

In order to keep the administration between our companies optimum – as mentioned earlier we will take the unusual step to send the part with the labour allowance. In return, we kindly ask for confirmation using this link to confirm the countermeasure has been completed and these units can operate in a safe manner.

We apologise for the inconvenience this problem might cause to you. If you have any questions or remarks, please contact Daikin UK Service Department or your Sales Engineer.
Yours sincerely,

Mark Dyer
Deputy Managing Director
