Conguration
A remote low side cuber system includes two sub
systems: an ice making head and a remote air cooled
condensing unit. This manual covers the EH222 head
and the condensing units that go with it.
The ice making heads are designed for use indoors
in a controlled environment. The remote condensing
units are designed to operate outdoors. Each sub-
system has limits for power, water and temperature.
Operational Limitations:
Minimum Maximum
Air Temp (at head) 50oF 100oF.
Air Temp (CU) -20oF. 120oF.
Water Temp 40oF. 100oF.
Water Pressure 20 psi 80 psi
Water Conductivity 10 microSiemens/cm any
Voltage (at head) 104 126
Voltage (CU) 198 253
CU= Condensing Unit
Do Not operate the machine in conditions beyond
these limitations. Doing so will void the warranty.
Scotsman ice systems are designed and
manufactured with the highest regard for safety and
performance. They meet or exceed common agency
standards.
Scotsman assumes no liability of responsibility of
any kind for products manufactured by Scotsman
that have been altered in any way, including the use
of any part and/or other components not specically
approved by Scotsman.
Scotsman reserves the right to make design changes
and/or improvements at any time. Specications and
design are subject to change without notice.
Warranty
Refer to the warranty coverage in effect when the
equipment was sold. Warranty statements are
included with each product.
Systems:
Ice making heads and condensing units have their
own model and serial numbers. 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
System Information
Tubing kits are required to connect the head to the
condensing unit.
Interconnecting 24 volt control wire ships with the
condensing unit.

Pre-Installation Details
Note: The ice making section cannot be stacked
vertically.
Accessories such as bin adapters and tubing kits are
required to complete the installation.
Dispenser Adapter Kits:
• Cornelius ABS: KBTABS ED150: KBT40
• Scotsman ID150: KBT40
• Scotsman ID200 or ID250: KBT41
Bin Adapter Kits:
• B530P or B530S: KBT32
• B948S: KBT34
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. The
condensing section may have quick connects. See
refrigeration system detailed instructions connection
details.
Items required for installation:
• 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 22” wide by 16.5”
deep. The refrigeration connections can be routed up
or to the back. The drain may be routed out the back
at any position left to right; it may also be routed to
either side.
Water
Pure water does not exist. All water supplies contain
some amounts of impurities, although potable water
is, by denition, 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.

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 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: 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.
Lineset Ice machine head and condensing
unit both have stubs
Ice machine head has stubs, condensing
unit has quick connects.
Has Quick Connect Fittings Cut quick connects off both ends Cut off quick connects at condensing unit
end only
Does NOT have Quick
Connect Fittings
Use as supplied Use as is at head, obtain kit KTE6-EH,
use 3 of 6 ttings on condensing unit end.

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 roong 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 efciently. 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 Piercing:
The roof (or wall) must have a passage 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.
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.
