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-
1.5 lb. (24 oz) (0.68 kg)
30.5 m), add
nameplate charge.

Typical Additional Refrigerant Label
If there is no additional label, the nameplate charge is
sufficient for line sets up to 100' (30.5 m). (See the chart
below.)
Potential Personal Injury Situation
The ice machine contains refrigerant charge. Installation of
the line sets must be performed by a properly trained and
EPA certified refrigeration technician aware of the dangers
of dealing with refrigerant charged equipment.
