How it works

Manufacturer charge allowance worksheet

Record the refrigerant and exact system document, then total the manufacturer's stated base mass and separately chargeable line lengths. Enter only lengths to which the selected coefficient actually applies, after handling included lengths and component rules exactly as the manual specifies.

Worksheet total kg = documented base kg + sum(chargeable length m × coefficient g/m) ÷ 1000 + documented adjustment g ÷ 1000.

FAQ

No. It totals the entered manufacturer-based charge basis. Existing charge, recovery, service procedures and the actual amount to add must be determined by the qualified installer using the exact equipment instructions.

Use the actual source documents, units and operating conditions shown in the selected mode. Replace illustrative examples with your records, enter explicit zeros only where valid and retain unresolved assumptions.
