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:
• 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.
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.

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 o.
If the head or condensing unit has a quick connect,
recover refrigerant and only cut o 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.
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.

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 eciently. 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 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.
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.

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.

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.

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. 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.
7. 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 curtains and
observe that 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 a curtain during the Freeze cycle has no
aect 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 fan stops and 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 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.
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.

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 or replace the air lter and clean the air cooled condenser (air cooled models only).
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.
The ice machine’s water system should be cleaned and sanitized a minimum of twice per year. Sanitize the
ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and
sanitized.
Preparing to Clean:
1. Remove the front panel.
2. Remove the evaporator cover.
Scale Removal:
3. Push and release the Clean button. The yellow
Clean light will blink and the display will show C.
The machine will harvest any ice, drain the reservoir
and begin to rell it.

5. Pour the below specied amount Scotsman Clear
1 ice machine scale remover into the reservoir. The
unit will circulate the scale remover, then drain and
ush it. This will take 35 minutes, then the machine
will stop and the display will show O.
Note: Using chemicals or dilution ratios other than
what is specied will damage the ice machine and
signicantly aect the performance and life of the ice
machine.

oz of Nu-Calgon IMS Sanitizer with 1 gallon (128
oz) of 105-115 degree F. potable water.
8. Remove air lter(s)(if applicable), water level sensor
and housing, water distributor(s), curtain(s), ice
thickness sensor, and splash panel for additional
cleaning.
9. Soak and scrub each part (including the
evaporator cover!) using the previously prepared
solution of Scotsman Clear 1 scale remover and a
nylon brush, and then rinse with water. Save scale
remover solution.
10. Soak and scrub each part using the previously
prepared sanitizing solution. No rinse needed. Save
sanitizing solution.
11. Using a non-metallic scouring pad, scrub spillway
with sanitizer to remove any material buildup and
debris.

What to do before calling for service
Reasons the machine might shut itself o:
• Lack of water.
• Freeze cycle takes too long.
• Harvest cycle takes too long.
• High discharge temperature.
• Controller self test failure.
Check the following:
1. Has the water supply to the ice machine or
building been shut o? If yes, the ice machine will
automatically restart within 25 minutes after water
begins to ow to it.
2. Has power been shut o to the ice machine? If
yes, the ice machine will automatically restart
when power is restored.
3. Has someone shut the water o to a water
cooled unit? If yes, after the water supply has
been restored the ice machine may need to be
manually reset.
4. 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.
To Manually Reset the machine.
• Open the switch door
• Push and release the O button.
• Push and release the On button.
To Shut the Machine O:
1. Push and hold the O button for 3 seconds or until
the machine stops.
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 o, will result in the machine shutting o.
