refrigeration system detailed instructions connection
details.
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.
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.

EH222 E and Condensing Unit
Remote Low Side Cuber 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.
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.
Check condensing unit for quick connects. If none,
recover refrigerant from tubing and cut the quick
Exposed tubing: Minimize the amount of tubing
exposed outdoors.

Connect Fittings
Use as suppliedUse as is at head, obtain kit KTE6-EH,
use 3 of 6 ttings on condensing unit end.
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.

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 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.
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 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 EH222 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.

connector and install a ¾” FPT female copper tting
onto the ¾” NPT male tting. Do all soldering before
connecting to the male tting.
2. In tight locations do the next step after the unit is
placed on the dispenser or bin.
3. Connect rigid drain tubing to the reservoir drain
tube. Route the drain either out the back, under the
unit (through the notch in the base) to the left side
or to the right side. A vent is built into the unit, so no
external vent is required.
Run the drain tubing to the building drain. Do not
“Tee” into any other drain, including the bin or
dispenser drain.
Left Draining: Rotate elbow to the other direction.
Connect ¾” PVC to the PVC tting.
Back Draining: Rotate elbow to face the back or
connect PVC directly into the ¾” FPT drain tting.
No external drain vent is required, venting is internally

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 EH222.
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. F will 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.
Note: Moving the curtain during the Freeze cycle has
no affect 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
EH222 opens, and the harvest assist mechanism
activates. In the CU the condenser bypass valve
opens and the receiver inlet valve closes. In the
EH222, the purge valve opens to drain some water,
when it does the inlet water valve opens to rell 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.
6. Go to the condensing unit and conrm 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 Off when returned to its normal
position.

Adjustable Ice Level Control
There is an adjustment post and an additional
indicator light to the right of the four indicator lights.
The ultrasonic ice level control allows the user to
control the point that the ice machine will stop making
ice before the bin or dispenser is full. Reasons for this
include:
• Seasonal changes in ice used
• Planning to sanitize the bin
• Certain dispenser applications where maximum
ice level is not desired
Use of control
There are several positions the ice level can be set
to, including Off (knob and label indicators lined up),
where it lls the bin until the standard bin control shuts
the machine off.
Ice
The cuber drops ice in large sections. That ice will
break up into random parts as it falls into the bin, but
some large sections may remain on top of the ice
in the bin. In a dispenser this ice will break up into
mostly individual cubes as the dispense mechanism
moves the ice.
Noise
The ice machine will make little noise when it is in
ice making mode. The compressor and fan motor are
remote from the ice making head. The water pump
in the ice making head will produce some sound. It
is also normal to hear some cracking just before the
harvest cycle begins. In addition, during the harvest
cycle the harvest assist solenoid will click twice as it
pushes the ice out and returns to its normal position.
The ice harvests as a unit or slab, which makes some
noise when it impacts the bin or dispenser. These
noises are all normal for this machine.
Rotate the adjustment post to the desired ice level.
The machine will ll up to that level and when it shuts
off the indicator light next to the adjustment post will
be On.
Suggested Adjustment Knob Position for use with the
ABS or Freestyle: rst CW position - as shown above.
DO NOT ADJUST TOO LOW OR THE MACHINE
WILL STOP MAKING ICE
Note: Ice will build up in the bin or dispenser at an
angle, the distance set will be from the sensor to the
top of the ice. The sensor position is shown in the
cabinet layout diagrams.
The actual distance between the highest point of the
ice may be closer or further away than the distance
set, depending upon the angle of the ice.

Cleaning, Sanitation and Maintenance
This ice system requires three types of maintenance:
• Remove the build up of mineral scale from the ice
machine’s water system and sensors.
• Sanitize the ice machine’s water system and the
ice storage bin or dispenser.
• Clean the remote air cooled condenser.
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their
water systems with a specically designed chemical. This chemical dissolves mineral build up that forms during
the ice making process.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is
cleaned and sanitized.
The ice machine’s water system should be cleaned
and sanitized a minimum of twice per year.
Note: If unit has not been de-scaled for an extended
period of time and signicant mineral scale remains,
repeat steps 5 - 10.
1. Remove the front panel.
7. Mix a cleaning solution of 1 oz of ice machine

What to do before calling for service:
Reasons the machine might shut itself off:
• Lack of water.
• Freeze cycle takes too long.
• Harvest cycle takes too long.
• High discharge pressure.
• Ice level control set wrong
Check the following:
1. Has the water supply to the ice machine or building been shut off? If yes, the ice machine will automatically
restart within 25 minutes after water begins to ow to it.
2. Has power been shut off to the ice machine? If yes, the ice machine will automatically restart when power
is restored.
3. Is the curtain open because some ice is stuck under it? If so, remove the ice and the machine should start
in a few minutes.
4. Check the adjustment knob of the ice level control. See page 21.
Note: Curtain can be removed & replaced anytime the machine is in a standby mode or when it is in a freeze
cycle. However, removal of the curtain during freeze will result in water owing into the bin. Removal of the
curtain during harvest terminates harvest at that point and, if left off, will result in the machine shutting off.
To Manually Reset the machine.
1. Open the switch door.
2. Push and release the Off button.
3. Push and release the On button.
To Shut the Machine Off:
1. Push and hold the Off button for 3 seconds
or until the machine stops.
