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.

Remote Low Side User 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.
Check condensing unit for quick connects. If none,
recover refrigerant from tubing and cut the quick
connects o󰀨.
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 MC222 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 o󰀨 both ends Cut o󰀨 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 e󰀩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.
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 with the ball valves open.

Place Ice Making Head
Remove from carton.
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. The adapter to
ice head base MUST be sealed with gasket tape or
food grade sealant.
Attachment
ABS (Automatic Beverage Dispenser) in drive up
installations: Route refrigerant tubing and install drain
and water supply tubing onto ice making section
before placing unit on the dispenser.
Place MC222 onto adapter, do not secure at this time.
Uncoil power cord and route to the power supply.
Plug interconnecting control wire to the wire harness
in the ice making head.
Located at the top panel:
• Refrigeration connections.
• Interconnecting control wire.
• Access port for water supply.
• Power cord.
The drain may be routed to the left or right, allowing
the ice making section to be placed with its back tight
against a wall.
Water and Drain
The ice maker requires an adequate potable water
supply and a gravity drain.
Determine how the drain will be connected to the ice
making section.
• If access is available behind the unit, route the
drain in from the back.
• If the unit is to be ush mounted to the back of
the dispenser and tight against the wall, route the
drain out either the left or right.
In some tight situations it will be necessary to
assemble the ice making section to the dispenser or
bin and install the water and drain connections before
placing the system in its installed position. A loop of
water supply tubing will aid movement of the system.
In other tight situations the unit should have its water
and drain tubing connected and stubbed out before
placing on the dispenser or bin.
The drain tting is adaptable to drain connections to
the left, right and back.
The unit is shipped ready to drain right. The drain
tting elbow with PVC adapter can be rotated to drain
right, left or back.

Cycle Denitions:
Freeze: The refrigeration system is operating to
remove heat from the evaporators. The compressor,
fan motor, and water pump are on.
Harvest: The refrigeration system and water system
are operating to harvest the ice and rinse the
reservoir. The compressor is on for the full cycle, the
pump is on until the purge valve closes.
The inlet water valve opens and rells the reservoir.
The vapor and condenser by-pass valves are open
during the entire harvest cycle, as is the harvest assist
mechanism.

Initial Start Up
Pre Start
A soak-out period of four hours is optional for this
system. If desired, powering the compressor unit
for four hours prior to start up allows the crankcase
heater to warm up the oil in the compressor.
Start Up
1. Connect power to the condensing unit and move
its toggle switch to Run or On.
2. Open the water supply valve.
3. Switch on the electrical power to the MC222.
Observe that some of the lower control’s indicator
lights glow and its display shows O.
4. Locate lower light and control panel.
5. Push and release the ON button on the lower
panel. The code display will begin to blink F.
The purge valve opens, the water pump starts and the
inlet water valve opens to add water to the reservoir.
In a few seconds the purge valve closes and the
water pump stops. Water will ow into the machine
until the reservoir is full. The vapor valve and harvest
assist device will activate, then the compressor and
water pump will start. Fwill be on steady.
Note: Because the condensing unit is external to the
ice making section, no visible signs of operation will
be noticeable until the water begins to cool and frost
forms on the evaporator tubing.
6. Go to the condensing unit and conrm that the
compressor and fan motor are operating. Warm
air will be discharged from the condenser.
Observe the Ready for Harvest indicator light. It may
blink early in the cycle, that is normal. The control will
ignore that signal for the rst 6 minutes of freeze.
During the Freeze cycle move the curtain and observe
that either the SW1 or SW2 light on the control
board blinks On when the curtain moves away from
the evaporator and O󰀨 when returned to its normal
position.
Note: Moving the curtain during the Freeze cycle has
no a󰀨ect on control function, but will cause water to
ow into the cube chute.
When enough ice has frozen, the Ready for Harvest
indicator light will be on steady. After it’s been on
steady for a few seconds Harvest will begin.
The display shows an H. The vapor valve in the
MC222 opens, and the harvest assist mechanism
activates. In the CU the condenser bypass valve
opens and the receiver inlet valve closes. In the
MC222, the purge valve opens to drain some water,
when it does the inlet water valve opens to rell the
reservoir. After a few seconds the purge valve closes
but the inlet water valve continues to ll the reservoir.
Harvest continues until the ice is released as a unit
and forces the curtain to open.
When the curtain opens it signals the controller that
harvest is complete, and it returns the unit to a freeze
cycle.
7. Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 1/8 inch.
If needed, adjust bridge thickness. Do NOT make
it too thin.
8. Instruct the user in the operation of the machine
and its maintenance requirements.
9. Fill out and mail the warranty registration form or
register it on line at www.scotsman-ice.com.
