What is live in Path D right now?

The pre-start and first start-up module, its graded RTU First Start-up Sequence lab, and the free start-up and commissioning checklist. Remaining modules release progressively.

Is the start-up lab free?

Yes. The RTU First Start-up Sequence lab is public and playable without an account.

Do I need Path C first?

It helps but is not required. Path C teaches diagnosis on existing rooftop equipment; Path D teaches getting new equipment running correctly.

Does this replace manufacturer start-up documentation?

No. Always follow the equipment manufacturer's start-up procedure. This path teaches the judgment and sequence behind it.

Path D

Installation, Start-up & Commissioning

Install it, start it correctly, and prove it with numbers. This path takes technicians from service-only work to equipment that is set up right the first time and handed over with a record that stands up months later.

Who this is for

Service technicians asked to run or verify their own installations
Install crews who want the start-up and commissioning half done properly
Owners who keep paying for callbacks that trace back to start-up shortcuts
Commissioning agents and supervisors verifying other people's work

Install → start up → verify

Run a pre-start checklist and know when to refuse to energise the unit
Execute a first start-up sequence in the correct order, stage by stage
Prove fan rotation, airflow and static pressure before touching refrigerant
Braze, pressure-test, evacuate and charge to a documented standard
Recognise the start-up faults that become callbacks weeks later
Leave a commissioning record the customer and the next technician can use
