Note:
• During a charge cycle, if the unit fails to transfer
refrigerant due to low tank pressure, the charge
process is automatically interrupted and the unit
operates in a mode to build tank pressure. Once
tank pressure is sufcient, the unit automatically
completes the charge.
•
When the charge cycle gets close to the weight
entered in Step 2, the unit slows down. It’ll charge,
settle, charge again, settle, etc.
