REMOTE ICE MACHINES
REFRIGERANT CHARGE
Each remote ice machines 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 serial
tag 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.)

EPA CERTIFIED TECHNICIANS
If remote line set length is between 50’ and 100’
(15.25-30.5 m), add 1.5 lb (24 oz) (0.68 kg) of
refrigerant to the nameplate charge.
