Step 6 - Charging; Step 7 - System Test; Step 8 - Explaining Operation To The End User - Haier 2U18MS2VHB Installation Manual

Charge the system using the weight method.
The unit comes with enough charge for 25 feet per circuit.
For example, the 2 port unit will come with 50 feet of charge,
the 3 port unit will come with 75 feet of charge, and the 4
port unit will come with 100 feet of charge. If the system
must have additional charge added, add .2 ounces of charge
for every additional foot of refrigerant line that is above
factory charge. If the total of distance of the installed line
sets is below factory charge, the factory charge is sufficient.
Simply release the charge by opening the system service
valves.
