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 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.
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.

EH330, EH430 D and ECC 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.
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.

System Example
October 2014
Page 11
EH330, EH430 D and ECC Condensing Unit Remote Low Side Cuber User Manual
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 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.
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.

Place Ice Making Head
Remove from carton.
Remove all panels.
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.
Communication Cable
Plug the interconnecting communication cable into the harness at the back of the head unit’s electrical box.

Condensing Unit Electrical
Route interconnecting control wire through proper hole in side of CU unit and plug into the connection on 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.
Three Phase Notice: Check voltage between legs at contactor. If there is a “wild leg” in the three phase power supply move supply wires so the higher voltage is on L3 of the contactor, which connects to the compressor motor only.

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.

3. Remove the head’s front panel. Check for any packing or wires rubbing moving parts. Note location of control board in upper left corner of the machine’s front.
4. Remove any tape securing curtain to evaporator.
5. Switch on the electrical power to the EH head. Observe that some of the control’s indicator lights glow and its display shows O.
6. Push and release the ON button. 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 valves and harvest assist devices will activate, then the compressor and water pump will start. The 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 a 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 EH opens, and the harvest assist mechanism activates. In the CU the condenser bypass valve opens and the receiver inlet valve closes. In the EH, 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.
8. 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.
9. Return the front panel to its normal position and secure it to the machine.
10. Instruct the user in the operation of the machine and its maintenance requirements.
11. Fill out and mail the warranty registration form or register it on line at www.scotsman-ice.com.
7. 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 curtains and observe that 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.

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 specically 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

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 19.
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.
