sets of up to 50' (15.25 m). The serial tag on the ice machine indicates the refrigerant charge.

Additional refrigerant may be required for installations using line sets between 50' and 100' (15.25-30.5 m) 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-

30.5m), add 1.5 lb. (24 oz) (0.68 kg) of refrigerant to the nameplate charge.
