Conguration
A remote low side cuber system includes two
sub systems: an ice head section and a remote
condensing unit. 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 condensing
units are designed to operate outdoors. Each subsystem has limits for power, water and temperature.
Operational Limitations:
Minimum Maximum
Air Temp (IH) 50oF 100oF.
Air Temp (CU) -20oF. 120oF.
Water Temp 40oF. 100oF.

IH = Ice Head, CU= Condensing Unit
Warranty
Refer to the warranty coverage in effect when the
equipment was sold. Warranty statements are
included with each product.
Systems:
Each sub-system is a separate entity that carries
its own model and serial number. They must be
combined to create a remote cuber low side system.
Notes: Voltage Codes are at the end of the model
number. Codes read Voltage/Hertz/Phase. Those
related to these products include:
-1 = 115/60/1
-3 = 208-230/60/3
-32 = 208-230/60/1
Tubing kits are required to interconnect the head to
the CU

Pre-Installation Details
Note: The ice making head cannot be stacked
vertically.
Accessories such as bin adapters and tubing kits are
required to complete the installation.
Dispenser Adapter Kits:
• Scotsman ID200 or ID250: KBT44
Bin Adapter Kits:
• B948S: KBT22A
Tubing Kits:
• 20 foot: 3BRTE20-EH
• 35 foot: 3BRTE35-EH
• 50 foot: 3BRTE50-EH
• 75 foot: 3BRTE75-EH
Note: Line set may have quick connects. See
refrigeration system detailed instructions connection
details.
Items required for installation:
Water
Pure water does not exist. All water supplies contain
some amounts of impurities, although potable water
is, by denition, t 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.
There are two ways water can contain impurities:
in suspension or in solution. Suspended solids can
be ltered out of the water. In solution or dissolved
solids must be diluted or treated. Water lters are
recommended to remove the suspended solids.
Some lters or lter 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.
• Ice making head
• Condensing unit (includes interconnecting control
system wire)
• Tubing kit. 20’, 35', 50’ or 75’ triple line set (liquid,
vapor and suction)
• Bin or dispenser adapter
Special Considerations
The ice making section’s footprint is 30” wide by 24”
deep plus another 1.5” for a utility chase on the back
panel. The refrigeration connections can be made to
go up or out the back by bending the line set tubing.
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.

Remote Low Side Cuber Service Manual
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.
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 nal 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.
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.

Place Remote System
Roof preparation
Most installations of this system will place the
condensing unit on the roof of a building. The roof
must be physically able to accept the load of the
equipment and the roong material must be prepared
to prevent water leaks.
Follow local codes for the placement and attachment
of the equipment.
Location
The condensing unit requires unobstructed air ow
to operate efciently. A four foot space between
each intake side and a wall or other cabinet is
recommended.
Do not place where it 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
condensing unit.
Roof Pipe Curb or Pitch Pocket:
To avoid potential kinking of the refrigeration tubing,
avoid small, tight radius types of covers on pitch
pockets.
Suggestions:
In most cases a mechanical lift, boom truck or crane
will be required to hoist the condensing unit.
Mount unit to roof rails or curbs and secure with lag
screws or similar eld supplied fasteners.
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.
Roof Piercing:
The roof (or wall) must have an opening
large enough for the three refrigeration 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.

Tubing
The line set must be routed between the condensing unit and the ice maker’s location. During the transition
from quick connects to braze connections, the ice maker, condensing unit and line set may or may not have
quick connects, use this chart as a guideline for the proper action based on what is available at the site.

If line set does not have quick connects,
route and use as is.
If line set has quick connects, recover
refrigerant from line set and cut all quick
connects off.
If line set has quick connects, recover
refrigerant from line set and cut one end
of quick connects off.
If line set does not have quick connects,
must use KTE6-EH stub kit to add for ice
machine end.
Compressor packs C1200CP,
C1410CP and C1800CP may be
connected to this head and will have
quick connects. If line set has quick
connects, recover refrigerant from line
set and cut one end of quick connects
off.
If line set does not have quick
connects, must use KTE6-EH stub kit
to add for condensing unit end.
If line set does not have quick
connects, must use KTE6-EH stub kit
to add for ice machine end.
Use the quick connects to make the
connection.
In all cases the line set will need to be shortened to t.
Do NOT leave excess line set exposed outdoors,
especially on a roof.
Refrigerant Recovery and System Evacuation Notice
In the event the refrigerant must be recovered from this system and the system evacuated, recover and
evacuate from the three ball valve access valves.

Utility Connection Route:
Electrical: The unit is supplied with a power cord.
There is also an interconnecting control wire that
must be routed between the ice making head and the
condensing unit.
Water Supply: The water supply can be routed from
the top or back.
Drain: The drain must be routed out the back.
Refrigeration Tubing: Field bending will allow the
tubing to be routed up or towards the back.
Adapters:
In many cases an adapter kit will be required when
placing the head unit on a bin or dispenser. See
sales information for the correct kit. Place adapter
kit onto bin or dispenser top. If adapter does NOT
have gasket tape install tape such as Scotsman part
number 19-0503-04.
Note: External drain tubing must be supported to
insure that it does not move and kink the internal
rubber tube.

the side of the control box.
Route power conduit (liquid tight) and wires to the
hole in the side of the CU unit. Connect to wire leads
or terminal strip, if used, with the proper type of
connector.
Note: The power supply wires must be the correct
size and type per the National Electric Code.
Locate the nameplate on the CU unit for the Voltage,
Phase, Minimum Circuit Ampacity and Maximum Fuse
Size. Either fuses or HACR type circuit breakers may
be used.
Follow all Local, State and National Codes.

Water and Drain
All models require connection to cold, potable water.
A hand actuated valve within sight of the machine
is required. There is a single 3/8” FPT inlet water
connection.
Water Filters
Install a new cartridge if the lters were used with a
prior machine.
All models require drain tubing to be attached to them.
There is a single ¾” FPT drain tting in the back of the
cabinet.
Install new tubing when replacing a prior ice machine,
as the tubing will have been sized for the old model
and might not be correct for this one.
1. Connect water supply to water inlet tting.
Note: This NSF listed model has a 1" anti-back ow
air gap between the potable water inlet tube end and
the highest possible reservoir water level, no back
ow device is required.
2. Connect drain tubing to drain tting.
3. Route the drain tubing to building drain. Follow
local codes for drain air gap. Use rigid drain tubes
and route them separately – do not Tee into the bin’s
drain.
Vent the reservoir drain. A vertical vent at the back
of the drain, extended about 8 – 10” will allow the
gravity drain to empty and also keep any surges
during draining from discharging water.
Horizontal runs of drain tubing need a ¼” per fall per
foot of run for proper draining.
Follow all applicable codes.
