Read past 48TC

Copy the full nameplate string, including the letters before the size code and everything after it. Keep a clear nameplate photo with the unit tag. If a character is unreadable, leave it unresolved instead of borrowing it from the next rooftop.

• Record the site’s equipment tag separately from the manufacturer’s model.
• Keep the serial number in the equipment record, not in a public search URL.
• Use the nameplate to confirm refrigerant and electrical information.

Record which control is actually fitted

The cited nomenclature includes electromechanical, PremierLink and RTU Open choices. Photograph the installed control label and keep its document number beside any observed message. A replacement control or field-installed accessory needs its own reference.

• Controller name and label photograph.
• Economizer or other accessory identification, where relevant.
• Observed indication, when it appeared and operating conditions.

Give the parts desk a complete record

The model prefix is a starting point for a parts conversation. Send the full unit identity and the actual component label through your normal supplier channel. Keep the supplier’s confirmed part and any fit conditions with the quote.

• Unit model, serial and equipment tag.
• Component label and photographs showing the connections or mounting.
• Supplier-confirmed replacement, availability and assumptions.

Put the work under the right unit

Start a report with the model you entered, then add what you found and what you completed. Keep a proposed repair separate from completed work so the office can quote or schedule it without reconstructing the visit.

• Findings and work performed, with units beside readings.
• Photographs captioned with the unit and observation.
• Unfinished work, next action and who needs to follow up.

Review the full model before adding it. Existing work in your saved draft stays intact.
