long. If additional refrigerant is required, an additional
label located next to the Model/Serial Numbers decal
states the amount of refrigerant to be added.
IMPORTANT
EPA CERTIFIED TECHNICIANS
If remote line set length is between 50' and 100' (15.25-
1.5 lb. (24 oz) (0.68 kg)
30.5 m), add
nameplate charge.
