Configuration
A remote low side cuber system includes several
sub systems: an ice making section, a remote
compressor package, and a remote air cooled
condenser. Additionally, there are several models
of each sub-system and this manual covers all of
them.
The ice making sections are designed for use
indoors in a controlled environment. The remote
compressor packages and condensers are
designed to operate outdoors. Each sub-system
has limits for power, water and temperature.

Special Considerations
The ice making section’s footprint is 30” wide by
24” deep. The refrigeration connections can be
made out the top panel or out the back. The
electrical power cord and the water inlet line can
also be routed through either of those areas. The
drain may be routed out the back or to the left side.
Water
Pure water does not exist. All water supplies
contain some amounts of impurities, although
potable water is, by definition, fit for human
consumption. Because the contents of the water to
an ice machine directly impact its performance,
consideration should be given to improving the
water’s quality.
Accessories such as bin adapters and tubing kits
are required to complete the installation.

There are two ways water can contain impurities:
in suspension or in solution. Suspended solids can
be filtered out of the water. In solution or dissolved
solids must be diluted or treated. Water filters are
recommended to remove the suspended solids.
Some filters or filter systems have treatment
chemicals in them for treating the suspended
solids.
This ice machine has an adjustment for the
amount of water rinsed or purged. Water use
adjustments are customer convenience
adjustments; they are not factory defects and are
not covered by warranty.
Items required for installation:

Ice making section

Create the System
Plan the installation. The system consists of four
parts: the ice making section, the compressor
package, the interconnecting tubing and the
remote condenser. Of these, the biggest variable is
the interconnecting tubing.
Tubing: The tubing consists of three pre-charged,
insulated and sealed soft copper tubes. They each
contain a small holding charge of R-404A. 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.
Excess tubing must be either shortened at the job
site (recovering the holding charge, purging with
nitrogen when brazing and evacuating to 50
microns) or coiled up inside the building.
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: To make installation easier the
compressor and condenser are designed to be
assembled together on the roof. Some
installations will require the use of a hoist to lift the
components to the roof.
Interconnecting wires: An interconnecting wire
harness is included with the CP unit. One end
plugs into the ice making section and the other into
the compressor package. The system will NOT
operate without this harness.
Exposed tubing: Minimize the amount of tubing
exposed outdoors.

Note: Only these condensers may be used. They
do NOT contain a headmaster valve. That valve is
in the Compressor Package. Do NOT use any
other Scotsman condenser. Do NOT use these
condensers on any other Scotsman remote
product.
Pad mounting: The compressor and condenser
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 pre-charged tubing.
Elevation: CP unit limited to 35 feet above the ice
making section.
Compressor package: Electrical power must be
supplied to the compressor package. The remote
condenser fan motor takes its power from the
compressor package.
Ice making section location and attachment:
The 115/60 Hz ice making section is cord
connected and requires an outlet within 6 feet of
the installation.
·
Interconnecting tubing kit
Note: Check tubing integrity before assembly by
attaching a refrigeration compound gauge onto
one of each tube’s schrader valves. If there is
pressure, the tube is OK, if not it should be
checked for damage and leaks.

System Examples
A variation of the typical system set up is one that
uses a non-Scotsman condenser. In that case the
CP unit is NOT bolted to the condenser and a
RTE10 line set is used to connect the refrigeration
system to the condenser’s coil.

Place Remote System
Roof preparation
Most installations of this system will place the
compressor package and condenser on the roof of
a building. The roof must be physically stout
enough to accept the load of the equipment and
the roofing material must be prepared to prevent
water leaks.
Follow local codes for the placement and
attachment of the equipment.
Location
The air cooled condensing unit assembly requires
unobstructed air flow to operate efficiently. A four
foot space between each intake side and a wall or
other cabinet is recommended. Provide at least 2
feet of space above the air cooled condenser for
proper air flow.
Do not place where the air cooled condenser will
pick up hot discharged air from an air conditioner
or other refrigeration system condensing unit.
Space must also be reserved for service on the
compressor package.
Roof Piercing:
The roof (or wall) must have a passage large
enough for the three pre-charged, pre-bent tubes
and the control wire to pass through. The minimum
recommended size is 4” ID. In most areas the
power supply may also pass through the same
passage. If there isn’t a passage one must be
created. In most cases this must be done by a
licensed and bonded roofer in order to maintain the
roof’s integrity.
Suggestions:
Hoist the compressor package and condenser to
the roof in separate loads.
Note: In most cases a mechanical lift, boom truck
or crane will be required to hoist the condensing
unit components.
Assemble the compressor package to the
condenser and mount both to either roof rails or
pressure treated4x4s.
Orient the assembled unit so that the unit’s mounts
are parallel to the pitch of the roof to allow water to
drain freely.
Do NOT place the unit directly onto roof rock.

Route Tubing
Prodigy Eclipseä 1200, 1400, 1800, 2000
Scotsman’s pre-charged tubing kits are pre-bent to
fit the connection path at the ice making section.
If the tubing is to be routed out the back, use
·
the straight ends.
Suction
Vapor
Liquid
If the tubing is to be routed out the back and
·
then up, use the ends with the single 90
degree bends.
Suction
Select the correct end to send to the roof.
The method or technique used to route the tube is
left to the installer. However, in many cases it is
easier to position the tubing inside the building
first, then feed the outside portion through the
tubing passage (pitch pot). Installation of tubing will
be easier if the suction line is run first, followed by
the liquid and vapor lines. Use of two persons is
suggested to prevent kinking of the tubing, long
runs may require three people.
Allow enough tubing to make large radius bends
·
from the roof passage to the compressor unit.
Do NOT leave excess tubing on the roof.
If a trap must be installed, the suction line
·
tubing must be cut apart to install it.
Identify the ice machine end of the tubing. Each
·
tube has one end formed to route through the
hole in the unit’s top.
Tape the ends of the vapor and liquid line tubes
·
together along with the interconnecting wire.
Extend the end of the interconnecting wire
about 2 feet beyond the end of the precharged
tubes and then tape it back onto the tubes.
·
Route the three tubes and the wire from the
roof, or other entrance, to the ice making
section’s planned position. Avoid uncoiling and
recoiling the tubing, as that can lead to kinks.
Vapor
Liquid
Note: Units mounted against the wall require
refrigerant connections out the top, water supply in
from the top, and power supply routed through the
top.
·
Support long runs of tubing with hangers.
·
Repair any tears in the tubing insulation,
especially those on the suction line that are
inside the building.
Shortening Tubing
The precharged tubing kits are available in a
variety of lengths, they should only be shortened if
absolutely necessary.
To Shorten Tubes:
1. Recover the 3 ounce R-404A holding charge
from each tube.
2. Cut out the required length of tubing, do not cut
the tubing right at the quick connects.
3. Attach nitrogen bottle to one quick connect and
a hose with a depressor to the other end, purge
nitrogen through each tube while brazing.
4. Remove nitrogen, evacuate to 200 microns.
Note: If tubes are connected to the IMS, evacuate
the vapor & suction lines to get the entire system.
