Prepare Pre-commissioning Package Documents

1. A copy of the refrigerant piping system(s) shop drawing(s) generated by LATS Multi V pipe design software.
2. A copy of the pipe fitter's pipe changes and field notes.
3. A verified copy of the "As-Built" LATS Multi V Project file (*.mtv) that includes all changes noted by the pipe fitter(s) in 2. Notes should
include changes to the line lengths and # elbows used for each liquid line segment
4. A copy of a completed and verified Installation Checklist for the water source unit, indoor units, ERVs, Air Cleaners, and Control Devices.
Correct any needing attention before continuing.
5. A copy of the water circuit control sequence of operation.
6. A water circuit flow balancing report.
7. A completed Pre-commissioning Device Configuration Worksheet.
8. A completed copy of the Pre-commissioning Checklist.
9. If an AC Smart Central Controller is provided and it is to be connected to the building network, record the IP Address on the Pre-commis-
sioning Device Configuration Worksheet.
Optional, but Highly Recommended
It is always best if the air balance is completed prior to a request for a commissioning agent to insure the air volume delivered at each indoor
unit is per project specifications. The commissioning agent is not responsible for setting the indoor unit fan speed or ensure the air volume
delivered at each indoor unit is per project specifications. Excessive or restricted airflow may impact the ability of the commissioning agent
to successfully complete system commissioning. Upon completion of the air balance, the report should include the adjusted indoor unit's
fan speed (i.e., fan setting value) set by the Test and Balance technician to deliver cataloged air volume (CFM) at jobsite static pressure
conditions.
Initiate a Request for a System Commissioning
Contact your LG Applied Representative's Project Manager or your account representative and request a System Commissioning. Provide
all the documents listed in "Prepare Pre-commissioning Package" section above.
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 commissioning agent.
After Commissioning Has Been Requested
The commissioning agent 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 commissioning agent's allotted time at your project DOES NOT include owner training.
It is understood that the contractor is to request for a commissioning agent 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
commissioning agent including but not limited airfare, travel costs, transportation, shipping, labor, and tool costs due to lack of readiness.
The commissioning agent's schedule is usually very rigid, and may have no flexibility regarding duration. It also involves advance travel ar-
rangements that may be impractical or impossible to change.
