Replace the failed unit while checking which existing interfaces remain useful.
Confirm the replacement specification
Identify unit, collection system, low-voltage controls and inlet layout. Ask the provider to compare support, electrical requirements, exhaust where applicable and compatibility with retained pipework.
Resolve the cause before closing the work
A new power unit cannot clear every concealed blockage or damaged pipe. Additional inlets and redesigned routes belong in a separate first-installation or improvement scope.
Specify the handover before ordering
Agree the completion checklist before the replacement is ordered: replacement identity recorded, agreed inlet operation checked, pipework and care limits explained. Identify who supplies the product, removes the old item and restores adjacent finishes. The final invoice should distinguish the replacement from any separately approved correction discovered once the existing component is exposed.
What shapes the scope?
- Unit and collection specification
- Mounting power and exhaust
- Retained controls and inlets
- Diagnostic and disposal scope
What should be checked?
- Replacement identity recorded
- Agreed inlet operation checked
- Pipework and care limits explained
Questions worth asking
What should be settled before the new item is ordered?
Start with unit and collection specification and mounting power and exhaust. Add dated photographs and describe when the concern occurs. A precise brief helps the provider decide what can be assessed on the first visit and what needs a separate investigation.
What belongs in the completion record?
Keep the exact replacement identity, the agreed checks and any unresolved limitation together. Pipework and care limits explained. Use Maintaining for its subsequent care, with the new manual rather than the old product’s assumptions.
