Requested the demonstrated reference. Seller says it's an older arrangement and offers to move our nest. We haven't agreed any layout change.

Moving the nest changes your job. Ask who would design and check the complete revised arrangement, including hose routing and release, before anyone prices it as a simple relocation.

Has the seller actually confirmed the original adapter is unavailable? Older doesn't answer that.

And the original sample evidence belongs to its actual configuration. Don't accept it as the substitute's trial merely because the same housings appear in both offers.

Anil, technical contact found the original reference in their parts records and is checking stock. Leah, nest relocation has no defined design or cost. It stays outside our accepted order.

That's the stock answer to pursue. Ask for the exact item identity on any replacement offer, not another description saying suitable adapter.

Original arrangement is available. Seller issued a replacement offer with its drawing and reference; our integrator confirmed it matches the accepted trial assembly. Return arrangements for the substitute are agreed.

Has it been dispatched, Jack, or is that still the agreed offer?

Carrier has collected the identified replacement. Substitute is packed under the agreed return reference. Installation remains paused pending receipt and the integrator's actual assembly check.

Replacement received, identity and assembly checked. The full housing sequence passed with the intended hose route and release. Stores now lists that adapter reference. Thanks, Anil; older hadn't meant unavailable.
