X-Series Pre-Commissioning Checklist
Checklist to prepare for commissioning, use prior to commissioning unit
Static Pressure:
Existing Static Pressure Reading (
should not be above 0.6*)
(Fill in):
New Unit Static Pressure Reading (Fill in):
*If existing unit has a PSC motor installed and the static pressure is above 0.6, add supply and return duct as needed.
Air Handler checklist, prior to install:
New Unit Holding Charge - double check the unit to make sure charge is holding prior to install
Y/N
Check for Position of New Air Handler
Horizontal-right
Horizontal-left
Upflow
Dip switch settings for air flow Level (Fill in):
Run start AH only test static pressure in factory default evel 4 (Fill in):
Adjust dip switch to the needed CFM at your current Static pressure
If default is too low increase the dip switch setting to your desired CFM see charts
Lineset guidelines
Accurately measure the existing refrigerant lines if they are over 25' and calculate the additional footage.
When brazing use Nitrogen purge throughout the process.
Torque down the flare nuts per industry standards.
Pressurize the lineset only, leak test the fittings and the braze connections, and verify that the system is 100% leak free.
Open the valves on the indoor unit only. Pull triple evacuation on the indoor coil and linesets.
Charging guidelines
If the line set is over 31’ add .32oz per foot.
Lineset Length

____________(oz)
ex. 50’ line set is over by 19’ multiply the overage 19’ x .32 =6.08oz of additional charge is required
