Create the System
Plan the installation. The system consists of three
parts: the ice making head, the condensing unit and
the interconnecting tubing. Of these, the biggest
variable is the interconnecting tubing.
Tubing: The tubing consists of three insulated and
sealed soft copper tubes. One tube, the liquid line,
is 3/8” OD. The vapor tube is ½” OD and the suction
tube is ¾” OD. A site inspection will determine what
length of tubing is required for the installation.
In 2013 Scotsman made a change to the Eclipse
tubing kits:
• Prior Tubing Kits: They each contain a small
holding charge of R-404A and have quick
connects at the ends.
• Current Tubing Kits: The do not contain any
refrigerant and do not have quick connects.
Either type can be used to connect the head and
condensing unit.
Check condensing unit for quick connects. If none,
recover refrigerant from tubing and cut the quick
connects off.
Excess tubing must be shortened at the job site.
Installations with greater than 20 feet of vertical lift
between ice machine and the compressor require
a suction line trap. The suction line requires careful
handling and large radius bends to prevent kinking.
Roof mounting: Some installations will require the use
of a hoist to lift the components to the roof.
Pad mounting: The condensing unit may be located
below the ice making section, up to a limit of 15 feet.
Distance from unit: Limited to the length of the
available tubing.
Elevation: Condensing unit limited to 35 feet above
the ice making section.
Condensing Unit: Electrical power must be supplied to
the condensing unit, it will be separate from the head.
Ice making section location and attachment: The
unique footprint of the EH222 requires adapter kits to
allow placement on dispensers and bins.
The remote tubing connections are at the top of the
machine, and connections should not be made until
the machine is nearly in its final installed position.
The 115/60 Hz ice making section is cord connected
and requires an outlet within 6 feet of the installation.
Interconnecting wires: An interconnecting wire
harness is included with the condensing unit. One end
plugs into the ice making section and the other into
the condensing unit. The system will NOT operate
without this harness.
Exposed tubing: Minimize the amount of tubing
exposed outdoors.
