the system will not start.
4. Air balance report showing proper airflow at all indoor units.
5. A copy of a completed and verified Installation Checklist for the outdoor unit(s), indoor units, heat recovery units, ERVs, Air Cleaners, and

The contractor should ONLY request commissioning when everything is completed and all components tested / addressed (if a component is
not operating within the usual parameters at the time of commissioning, then adjustments must be made that may prevent the Commissioner
from signing off and approving the system). Before commissioning, the
Commissioner may contact you to discuss specific job points, scheduled day(s) and expected duration. It is the contractor's responsibility to
provide all of the necessary start-up labor, refrigerant, tools and test equipment needed to complete the process in the expected time frame.
Do not attempt to start the outdoor unit(s), charge refrigerant, or open service valves until directed by your Commissioner. After commis-
sioning, the contractor will be notified if there are any corrections needed to allow warranty activation. The Distributor or LG Rep / Controls
Contractor may provide assistance with controls setup, final device programming, BMS integration, air balance adjustments, etc.; and pro-
ceed with any owner training (if included).
Using LGMV monitoring software is encouraged for ease of future diagnostic and maintenance related checks.
Initiate a Request for a System Commissioning
The system should now be ready for commissioning procedures and additional trim charge. Send all Pre-Commissioning Package Docu-
ments to your LG Applied Representative and request commissioning assistance.
System Commissioning
The Multi V System commissioning process and procedures are provided in a separate manual and/or in training materials provided by the
LG Academy Training Team. To obtain a copy, you must be a certified LG trained commissioner.
After Commissioning Has Been Requested
The LG trained commissioner may contact you to discuss specific job points, scheduled day(s) and expected duration. It is the contractor's
responsibility to provide all of the necessary start-up labor, refrigerant, tools and test equipment needed to complete the process in the
expected time frame. Please note that the LG trained commissioner allotted time at your project DOES NOT include owner training.
It is understood that the contractor is to request for a LG trained commissioner when all required project readiness points are complete; not
based on an "expected" completion date. The contractor also acknowledges that they will assume all responsibility for costs incurred by the
LG trained commissioner including but not limited airfare, travel costs, transportation, shipping, labor, and tool costs due to lack of readiness.
The LG trained commissioner's schedule is usually very rigid, and may have no flexibility regarding duration. It also involves advance travel
arrangements that may be impractical or impossible to change.
