Note: Line set may have quick connects. The
condensing section may have quick connects. See 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 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.
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.
October 2014

EH222 D 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 connects off.
Lineset Ice machine head and condensing
unit both have stubs
Has Quick Connect Fittings Cut quick connects off both ends Cut off quick connects at condensing unit
Does NOT have Quick Connect Fittings
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.
Use as supplied Use as is at head, obtain kit KTE6-EH,
Exposed tubing: Minimize the amount of tubing exposed outdoors.
Ice machine head has stubs, condensing unit has quick connects.

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 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.

Sometimes access to the switches should be limited
to prevent unauthorized operation. For that
purpose a xed panel is shipped in the hardware package. The xed panel cannot be opened.
To install the xed panel:
1. Remove the front panel and remove the bezel.
2. Spread the bezel frame open and remove
original door, insert xed panel into bezel. Be
sure it is in the closed position.
3. Return bezel to panel and install panel on unit.

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 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.

Right Draining:
1. Connect ¾” PVC to the female PVC tting.
If copper is required by code, remove the PVC
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 provided for.
Note: External drain tubing must be supported to insure that it does not move and kink the internal rubber tube.

Water Pump - on when the pump is
Purge Valve - on when the purge valve is
Water Solenoid - on when the inlet water solenoid
valve is
Hot Gas - on when the vapor inlet valve and harvest assist solenoid have power
Compressor - on when the compressor contactor is energized
Ready to Harvest - on when the ice thickness sensor has water touching it
Sump Empty - on when there is no water touching the mid-length probe
Sump Full - on when water is touching the shortest probe
SW2 - on when the curtain is open
SW1 - on when the curtain is open
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 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 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.
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 Off when returned to its normal position.
