Remote Condenser/Line Set Installation
REMOTE ICE MACHINES
REFRIGERANT CHARGE
Each remote ice machine ships from the factory with a
refrigerant charge appropriate for installation with line
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.
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.)
