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.
Quick Connect type: Check ice making head and
condensing unit for quick connects. If none, recover
refrigerant from tubing and cut the quick connects off.
If the head or condensing unit has a quick connect,
recover refrigerant and only cut off the quick connect
at the system with the stub connections.
Tubing without quick connects: Check head and
condensing unit, if neither have quick connects, use
as is. If one or both do, obtain kit KTE6 to add quick
connects to the line set.
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 head.
Condensing Unit: Electrical power must be supplied to
the condensing unit, it will be separate from the head.
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: A low voltage interconnecting
wire harness is included with the condensing unit.
One end plugs into the ice making head and the other
into the condensing unit. The system will NOT operate
without this harness.
Exposed tubing: Minimize the amount of tubing
exposed outdoors.
