SYSTEM CHARGE CHART - REFRIGERANT 410A
Pressure Requirements - Gross Charge Check ONLY
Sub Cooling Requirements - Final Charge Verification
NOTICE:
• It is required to fine tune unit charge. Indoor ambient temperature must be between
72°F and 82°F dry bulb at the indoor coil.
• Measure liquid line temperature at four (4) inches prior to metering device.
• Confirm the indoor supply air flow is correct, reference rated CFM in the unit Specification
Sheets.
• Allow the system to run long enough for temperatures and pressures to stabilize.
• Sub-cooling tolerance is +/- 1.5°F
• If obtaining rated sub-cooling values causes liquid/vapor pressures that are significantly
different (>20 psig) from those listed on the table, there may be a component or air flow
issue. Refer to unit Installation troubleshooting section for further support.
