Section 608 is about the refrigerant you handled, not a story about the old unit. The useful record is short: type, weight from a scale, cylinder identity, and whether you suspect a leak. The construction workflows live in the construction library.
What to look at
Weigh the cylinder before and after. Copy the refrigerant name from the nameplate, not from the color of the drum you hoped it was.
A field example
Field Air Co. recovered from a rooftop unit whose nameplate said R-410A. The cylinder was weighed at 42.6 lb before and 47.1 lb after. The log records those two weights, the cylinder serial, the equipment tag, and a note that the oil sample was not taken. A later tech did not have to guess whether the charge had been left in the machine.
What to leave unverified
If the charge was already gone, write that the system was empty. Do not backfill a typical factory charge and call it recovered.
Sources to open
Use 40 CFR Part 82 Subpart F for the recovery record, the equipment nameplate for the refrigerant type, and the scale ticket for the weight. Do not copy a factory charge from a catalog and call it recovered.
A practical next step
Keep the log with the equipment scrap or the install file. A startup sheet for the new heat pump is a different document and should not be mixed into the recovery line.
