Proper Combinations:
Eclipseä 1300,1600
The three sub systems are designed to be
connected together in certain combinations to meet
the user’s needs:
Eclipse 1300 System:
CME1386, CP1316, ERC1086
·
Eclipse 1600 System:
CME1686, CP1316, ERC1086
·
ERC1086 may be substituted for by an approved
central condenser coil & fan (coil must be without
headmaster - headmaster is part of CP1316).
Condenser coil internal volume target is 165 cubic
inches, BHTU target is 42,000 BTUH.
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:
Scotsman ID200 or ID250: KBT44
·
Note: Dispensers with two rotors. If possible, the
ice making head should NOT be centered left to
right between the two rotors. It should be shifted
slightly to one side, and the agitation should be
minimized.

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. The refrigeration connections can be
made out the top panel or out the back. 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.
The bin thermostat, when deployed, will be about
5” below the bottom of the cabinet, and that is
where the ice will fill to. This ice level maximizes
ice storage without overfilling the bin or dispenser.
Water
Pure water does not exist. All water supplies
contain some amounts of impurities, although
potable water is, by definition, fit 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 filtered out of the water. In solution or dissolved
solids must be diluted or treated. Water filters are
recommended to remove the suspended solids.
Some filters or filter 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 four
parts: the ice making section, the compressor
package, the interconnecting tubing and the
remote condenser. Of these, the biggest variable is
the interconnecting tubing.
Tubing: The tubing consists of three pre-charged,
insulated and sealed soft copper tubes. They each
contain a small holding charge of R-404A. 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.
Excess tubing must be either shortened at the job
site (recovering the holding charge, purging with
nitrogen when brazing and evacuating to 50
microns) or coiled up inside the building.
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: To make installation easier the
compressor and condenser are designed to be
assembled together on the roof. Some
installations will require the use of a hoist to lift the
components to the roof.
Pad mounting: The compressor and condenser
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 pre-charged tubing.
Interconnecting wires: An interconnecting wire
harness is included with the CP unit. One end
plugs into the ice making section and the other into
the compressor package. The system will NOT
operate without this harness.
Exposed tubing: Minimize the amount of tubing
exposed outdoors.

Note: Only these condensers may be used. They
do NOT contain a headmaster valve. That valve is
in the Compressor Package. Do NOT use anyother Scotsman condenser. Do NOT use these
condensers on any other Scotsman remote
product.
Interconnecting tubing kit
·
Note: Check tubing integrity before assembly by
attaching a refrigeration compound gauge onto one
of each tube’s schrader valves. If there is pressure,
the tube is OK, if not it should be checked for
damage and leaks.
·
Bin or dispenser adapter
Elevation: CP unit limited to 35 feet above the ice
making section.
Compressor package: Electrical power must be
supplied to the compressor package. The remote
condenser fan motor takes its power from the
compressor package.
Ice making section location and attachment:
The 115/60 Hz ice making section is cord
connected and requires an outlet within 6 feet of
the installation.

System Examples
A variation of the typical system set up is one that
uses a non-Scotsman condenser. In that case the
CP unit is NOT bolted to the condenser and a
RTE10 line set is used to connect the refrigeration
system to the condenser’s coil.

Eclipseä 1300,1600
Roof preparation
Most installations of this system will place the
compressor package and condenser on the roof of
a building. The roof must be physically stout
enough to accept the load of the equipment and
the roofing material must be prepared to prevent
water leaks.
Follow local codes for the placement and
attachment of the equipment.
Location
The air cooled condensing unit assembly requires
unobstructed air flow to operate efficiently. A four
foot space between each intake side and a wall or
other cabinet is recommended. Provide at least 2
feet of space above the air cooled condenser for
proper air flow.
Do not place where the air cooled condenser 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
compressor package.
Roof Piercing:
The roof (or wall) must have a passage large
enough for the three pre-charged, pre-bent 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.
Suggestions:
Hoist the compressor package and condenser to
the roof in separate loads.
Note: In most cases a mechanical lift, boom truck
or crane will be required to hoist the condensing
unit components.
Assemble the compressor package to the
condenser and mount both to either roof rails or
pressure treated4x4s.
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.

Route Tubing
Eclipseä 1300,1600
Scotsman’s pre-charged tubing kits are pre-bent to
fit the connection path at the ice making section.
If the tubing is to be routed out the back, use
·
the double-bend ends.
Suction
Vapor
Liquid
If the tubing is to be routed out the back and
·
then up, use the ends with the single 90
degree bends.
Suction
Select the correct end to send to the roof.
The method or technique used to route the tube is
left to the installer. However, in many cases it is
easier to position the tubing inside the building first,
then feed the outside portion through the tubing
passage (pitch pot). Installation of tubing will be
easier if the suction line is run first, followed by the
liquid and vapor lines. Use of two persons is
suggested to prevent kinking of the tubing, long
runs may require three people.
Allow enough tubing to make large radius bends
·
from the roof passage to the compressor unit.
Do NOT leave excess tubing on the roof.
If a trap must be installed, the suction line
·
tubing must be cut apart to install it.
Identify the ice machine end of the tubing. Each
·
tube has one end formed to route through the
hole in the unit’s top.
Tape the ends of the vapor and liquid line tubes
·
together along with the interconnecting wire.
Extend the end of the interconnecting wire
about 2 feet beyond the end of the precharged
tubes and then tape it back onto the tubes.
·
Route the three tubes and the wire from the
roof, or other entrance, to the ice making
section’s planned position. Avoid uncoiling and
recoiling the tubing, as that can lead to kinks.
Vapor
Liquid
Note: Units mounted flush against the wall require
refrigerant connections out the top, water supply in
from the top, power supply routed through the top
and drain routed to the left side.
·
Support long runs of tubing with hangers.
·
Repair any tears in the tubing insulation,
especially those on the suction line that are
inside the building.
Shortening Tubing
The precharged tubing kits are available in a
variety of lengths, they should only be shortened if
absolutely necessary.
To Shorten Tubes:
1. Recover the 3 ounce R-404A holding charge
from each tube.
2. Cut out the required length of tubing, do not cut
the tubing right at the quick connects.
3. Attach nitrogen bottle to one quick connect and
a hose with a depressor to the other end, purge
nitrogen through each tube while brazing.
4. Remove nitrogen, evacuate to 200 microns.
Note: If tubes are connected to the IMS, evacuate
the vapor & suction lines to get the entire system.

Water and Drain
Eclipseä 1300,1600
The ice making section requires an adequate
potable water supply and a gravity drain.
Determine how the water supply and drain will be
connected to the ice making section.
If access is available behind the unit, route the
·
drain and water supply in from the back.
If the unit is to be flush mounted to the back of
·
the bin or dispenser and tight against the wall,
the water supply must enter the cabinet through
the area in the lower back of the left side panel
or through the top panel with the refrigerant
lines.
If the unit is to be flush mounted to the back of
·
the bin or dispenser and tight against the wall,
the drain must be routed through the area in the
lower back of the left side panel.
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 allow 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 fitting is adaptable to drain connections
to the left or back.

Coupling Connections:
The couplings on the ends of the pre-charged line
sets are self-sealing when installed properly.
Follow these instructions carefully. These steps
must be performed by an EPA Certified Type II or
higher technician.
Initial Connections
1. Remove the protector caps and plugs. Wipe the
seats and threaded surfaces with a clean cloth to
remove any possible foreign matter.
4c. Continue tightening the swivel nut until it
bottoms out or a very definite increase in
resistance is felt (no threads should be showing).
Do NOT overtighten.
Tighten Swivel Nut
5. Use a marker or pen to mark a line on the
coupling nut and unit panel. Then tighten the
coupling nut an additional one-quarter turn. The
line will show the amount that the nut turns.
Clean and Lubricate Couplings
2. Thoroughly lubricate the threads, o-rings,
diaphragms and all internal coupling surfaces with
polyolester refrigerant oil.
3. Position the fittings on the correct connections
on the condenser and ice machine.
Final Connections:
4a. Begin to tighten the couplings together by
hand. Continue to turn the swivel nuts by hand until
it is certain that the threads are properly engaged.
4b. Using two wrenches, one to rotate the swivel
nut and one to hold the tubing in place, tighten
each coupling.
It is CRITICAL that ONLY the NUT on the
pre-charged tube be turned, or the diaphragms will
be torn by the piercing knives and become loose in
the refrigeration system causing severe operational
problems.
Note: As the coupling is tightened, the diaphragms
in the quick connect couplings will begin to be
pierced. As that happens, there will be increased
resistance to tightening the swivel nut.
Rotate Swivel Nut ¼ Turn More
6. After all connections have been made check the
couplings for leaks.
7. Add cork tape to the swivel nut of the suction
line to insulate it. Be sure all exposed tubing of
the suction line is insulated.
Note: The system charge is contained in the
receiver tank of the ice machine. Only “holding"
charges are present in the “pre-charged" tubing or
the condenser.

Final Placement
After the utilities and refrigeration connections
have been made, secure the unit to the dispenser
or bin top.
Secure ice making section to dispenser or bin
adapter.
Use strap/clips to secure unit. On some bins or
dispensers it may be necessary to drill small holes
and use field supplied sheet metal screws to
secure the ice making head to that bin, dispenser
or adapter.
If the ice maker & bin or dispenser is not yet in its
final position gently move it there.
Note: The refrigerant lines above the machine
must be able to move freely while the machine is
being moved into position.
Final Check List Before Initial Start Up
1. Confirm that the ice making section is installed
indoors in a controlled environment.
2. Confirm that all packing materials have been
removed from all products.
3. Confirm that the ice making section is level.
4. Confirm that all the refrigerant connections
have been made and checked for leaks.
5. Confirm that the proper power supply has been
turned on to the condensing unit.
6. Confirm that cold, potable water has been
supplied to the ice making section and checked
for leaks.
7. Confirm that the water supply is adequate.
8. Confirm that there is adequate water pressure
and that any water filters have been checked to
confirm that the cartridges do not need
changing.
9. Confirm that the proper size drain tubing has
been installed and properly routed.
10. Confirm that the ice making section has been
connected to the proper power supply.
11. Confirm that the interconnecting wire has been
routed and connected between the ice making

Initial Start Up - 1300 and 1600
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. Connect or reconnect power to the ice making
section.
4. Observe the lights on the controller:
All flash on as the power supply is reconnected.
·
The two red lights blink for 20 seconds while
·
some green lights are on. See page 43.
Note: If the light pattern does NOT match – do not
start the machine. Install a replacement controller
set to the correct program.
The red lights and harvest lights go out.
·
·The Off light turns on.
·
The Bin Full light will be on for a few seconds.
At this point the machine is ready for start up.
5. Push and Release the Freeze button to start the
machine.
·
The Freeze light will begin to blink.
·
The Purge valve will open for a few seconds
and then close.
·
The Inlet water valve will open and fill the
reservoir with water.
·
The Water pump will begin to circulate water
over the evaporators.
When the reservoir is full, the Freeze light will stop
blinking and the controller will close a circuit to the
compressor contactor to start the first freeze cycle.
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 confirm that the
compressor and fan motor are operating. Warm air
will be discharged from the condenser.
After a few minutes ice will begin to form on the
evaporators. When enough ice has formed to
nearly empty the water reservoir, the controller will
refill the reservoir. The next time the water level
drops that far, the ice is ready for release and the
Controller will initiate a Harvest cycle.
The Freeze light goes out and the Harvest light
·
switches on.
The vapor inlet valve in the ice making section
·
opens.
In the CP unit, the condenser by-pass valve
·
opens and the liquid inlet valve closes
The water pump stops.
·
The purge valve opens.
·
Refrigerant vapor flows into the evaporators where
it condenses, discharging its latent heat.
The evaporators warm up and melt the bond
between the ice cube surface and the evaporator
cells.
After about 20 seconds the water pump re-starts to
purge water out of the reservoir.
After a few more seconds the purge valve closes
and the inlet water valve opens for a few seconds
to add some water to the reservoir. The water
pump then circulates this water over the
evaporators, and ice begins to fall.
As the ice falls, it passes through two infrared light
beams. These beams, when interrupted, signal to
the Controller that ice is harvesting. The
interruptions are shown by the blinking of the Bin
Full light.
The first Harvest cycle continues for about 5
minutes. The controller will use the ice release time
measured during this time to compute the next
harvest cycle.
At the end of the Harvest cycle the ice machine will
switch back into a Freeze cycle.
The inlet water valve will open to re-fill the
reservoir with water, and the cycle repeats.
Note: Machines are shipped from the factory with
the purge level set to accommodate average water
conditions. To achieve optimal machine
performance, set the purge level to the minimum
setting. See the next page.
7. Attach the front panel to the ice making section.

Purge Adjustment
Note: While the amount of water purge is
adjustable, only those installations with a water
supply known to be excellent (very low TDS)
should adjust to the minimum setting. See below
for purge adjustment instructions.
How to Adjust the Amount of Water Purge
Adjustment is done by use of the control buttons
on the AutoIQ Controller. Examine the next section
to become familiar with the AutoIQ Controller
before beginning.
1. If the machine is on, push and hold the OFF
button for more than 3 seconds, then release it.
This switches the machine Off.
Eclipseä 1300,1600
Adjustments
Cube Size: Cube size is fixed and cannot be
adjusted.
Thermostatic Expansion Valve:
The TXV is not adjustable, do not attempt to adjust
it.
If there was a problem during Initial Start Up:
If an error light came on, check the following.
1. Water error.
A water error could have been determined by the
AutoIQ Controller if the inlet water valve does not
fill the reservoir, or if the water pump does not start
and lower the water level.
2. Push and hold the OFF button for more than 3
seconds (just until all lights flash on) then release
it. Do not hold it in it too long.
3. Examine the green lights. They should have all
flashed once, then certain ones will have turned on
to indicate which purge level the machine is set at.
There are 5 levels of purge available:
·1. Maximum Purge is when All 5 lights are ON.
Use for extreme water conditions.
·
2. Heavy Purge is when these 4 lights are ON:
Freeze, Harvest, Clean, Off. Use for severe
water conditions.
·
3. Standard Purge (factory setting) is when
these 3 lights are ON: Harvest, Clean, Off. Use
for moderate to severe water conditions.
·
4. Moderate Purge is when these 2 lights are
ON: Clean, Off. This is for typical water
conditions.
·
5. Minimum Purge is when this light is ON: Off.
For excellent water conditions.
Adjust by pushing and releasing the Freeze button.
Pushing and releasing the Freeze button increases
the purge one level up to the maximum, then it
goes to the minimum.
2. Refrigeration error.
A refrigeration error could have been determined
by the AutoIQ Controller if the water temperature
did not drop during the freeze cycle. The controller
will next check the compressor discharge
temperature, If the discharge temperature is too
low, the refrigerant error light will be switched on,
and the machine will Shut Down.
Note: Reset and restart the machine by
pushing and releasing the Off push button
switch, and then pushing and releasing the
freeze push button switch.
4. The machine will automatically restart after 60
seconds of no switch inputs, or restart the machine
by pushing in and holding the Off button for more
than 3 seconds, then releasing it. The unit will then
be Off. From there the machine may be placed in a
freeze cycle by pushing and releasing the Freeze
button.

Condenser sub-system:
The controller receives input from the water level
sensor, ice sensor and temperature sensor. It then
actuates various loads in the ice making section
and in the condensing unit to control ice making. It
also responds to push button input and displays
cycle and diagnostic indicators.
Freeze: At the ice making sub system, the
controller fills the water reservoir and starts the
pump and compressor to make ice. The vapor inlet
valve is closed. Water circulates over the
evaporators until it begins to freeze to the
evaporators. As ice builds up the water level in the
reservoir falls until it reaches a point where the
water level sensor indicates to the controller that
the water level is low. At that point, about half-way
through the freeze cycle, the controller opens the
water valve to refill the reservoir. The second time
the water level drops in the freeze cycle indicates
to the controller that the freeze cycle is complete.
In the air cooled condensing unit sub-system
(compressor package and condenser) the
compressor is on, the condenser by-pass valve is
closed, the fan motor is rotating the fan blade.
Harvest: At the ice making sub system, the
controller shuts off the pump, opens the vapor inlet
valve, opens the purge valve. The controller also
controls items in the condensing unit, where the
condenser by pass valve is opened. After a set
time the water pump restarts and shortly after that
the purge valve closes. The inlet water valve opens
to add water to the reservoir.
Ice releases and falls into the bin or dispenser.

Refrigeration Details:
Eclipseä 1300,1600
The compressor provides the force that circulates
refrigerant in the refrigeration system. During
freeze, when the vapor inlet and condenser by
pass valves are closed, discharge gas flows from
the compressor into the condenser, where its heat
is discharged into the air stream. Liquid refrigerant
flows out of the condenser and through the
normally open liquid line outlet valve on its way to
the receiver inlet. Under low ambient/low pressure
conditions, the headmaster valve closes the liquid
outlet of the condenser and opens a bypass route
to direct refrigerant gas to the receiver inlet until
discharge pressure builds back up to the
headmaster’s set point.
From the receiver liquid outlet, liquid
refrigerant flows into the liquid line
and into the ice making section. At
the ice making section, the
refrigerant flows into the expansion
valve where a pressure change
takes place. The liquid refrigerant
moves from the expansion valve
into a low-pressure area (the
evaporators) where it can rapidly
evaporate and absorb heat. Heat is
absorbed from the copper
evaporator tubing, attached copper,
tin, plastic and the water flowing
over the evaporators. The
CPR
Valve
low-pressure refrigerant gas then
flows into the suction line, which
carries it back to the condensing
unit, where it enters the
accumulator. In the accumulator
most of any liquid carried with the
suction gas is separated and only
vapor flows out of the accumulator
through the CPR valve and to the
compressor where the cycle
Vapor Inlet Valve
continues.
During harvest discharge gas flows
through the open condenser by
Suction Line
Manifold
pass valve into the vapor line.
Power is also applied to the coil of
the liquid inlet valve, closing it. At
the same time, in the ice making
section, the vapor inlet valve opens.
Discharge gas, combined with some
vapor from the receiver’s outlet,
then flows through the vapor line to
the evaporator inlets. The gas-vapor
combination, when entering the relatively cold
evaporators, condenses, transferring latent heat to
the evaporators, which warms them. Ice releases
and falls into the bin. The low-pressure refrigerant
then flows out of the evaporators and into the
suction line. The suction line brings the refrigerant,
now consisting of a vapor-liquid combination, to the
accumulator. From the accumulator the
vapor-liquid combination (now more vapor than
liquid) goes to the Crankcase Pressure Regulator
valve which limits the amount of dome pressure in
the compressor, where the cycle continues.

Technicians Only: Freeze Cycle Sequence of Operation
This sequence begins with a restart after the unit
has shut off with the bin full. Ice has been
consumed, causing the ice sensors to become
un-blocked.
1. The controller switches off the bin full light (four
minutes has to have passed since the machine
shut off on bin full for the machine to restart) and
switches on the Freeze light.
2. The purge valve is opened and the pump
started.
3. After the purge valve closes the inlet water valve
opens and fills the reservoir.
Note: If the water reservoir does not fill within the
time period expected the controller will shut off and
blink the water diagnostic light. It will re-try to fill
the reservoir in 20 minutes. If successful the freeze
cycle will continue.
4. The compressor and
fan motor start and the
freezing process begins.
6. Assuming that the system is working normally,
the controller will shut the water pump off for a few
seconds when the reservoir’s water temperature
reaches a pre-set point.
7. As the machine makes ice the water level in the
reservoir falls. When it reaches the point where the
float stem blocks the upper infrared beam in the
water level sensor the controller opens the inlet
water valve to refill the reservoir. The water valve
stays on until the float stem rises to block the lower
beam in the water level sensor.
8. The freezing process continues until the float
stem blocks the upper beam for the second time.
That signals to the controller that the freezing
process is complete.
5. The controller
measures the reservoir
water temperature and
compares it to the
temperature it expects to
find at that point in the
cycle. If normal, nothing
happens.
If high, the controller
checks the discharge
temperature. If that is
normal, nothing happens.
If that is low, the controller
starts a diagnostic
process that could lead to
the unit shutting off, as
the refrigeration system
may not be operable.

Technicians Only: Harvest Cycle Sequence of Operation
At the beginning of harvest, the controller:
Shuts off the Freeze light
·
Turns on the Harvest light
·
Opens the vapor inlet valve
·
Opens the condenser bypass valve
·
Closes the normally open liquid inlet valve
·
Shuts off the water pump
·
Opens the purge valve
·
Begins to time the harvest cycle
·
When the ice falls off the evaporators, it passes
through the two infrared light beams emitted by the
ice sensors in the ice chute. The falling ice breaks
the beams, signaling to the controller that ice is
being released.
During harvest the controller:
Blinks the Bin Full light at every light beam
·
interruption to indicate that ice is being sensed
Changes the time measured from the beginning
·
of harvest to the time the last cube was sensed.
First Harvest Cycle
The first harvest cycle after a restart continues for
a default period of about 5 minutes. The next
cycle’s harvest time will be determined from the
actual time used to release ice in this cycle, and
will likely be much shorter.
Slow Ice Release
If ice releases slowly the controller will extend the
harvest cycle until it ice quits falling within the
normal harvest time or until it reaches the pre-set
maximum time. The controller will then return the
unit to the freeze cycle.
No Ice Released
If no ice is sensed harvest continues until it
reaches its pre-set maximum, when the controller
switches the unit back into freeze.
Shut Down - Maximum Harvest Time
If a maximum harvest time is reached again during
the next harvest cycle, the controller will shut the
system down and blink the refrigeration diagnostic
light. It will automatically attempt a restart in 50
minutes. If the maximum harvest time is reached
again in the next two consecutive cycles, the
controller will repeat the shut down and restart
process. If the system still requires a maximum
length harvest cycle the controller will shut the unit
down and must be manually reset.
Purge Valve
The purge valve is open for a fixed time period. At
the beginning of that time the pump is off, but after
the time determined by the Purge setting in the
controller, the pump starts and forces water out of
the reservoir. The pump stays on after the purge
valve closes. The inlet water valve opens for a few
seconds to add water (but not fill) the reservoir.
End of Cycle
At the end of the harvest cycle the controller
switches the Harvest light off and the Freeze light
on. If the ice sensors had been blocked
continuously for more than 5 seconds the controller
senses this as Bin Full and would then shut the
machine off and turn on the Bin Full light.
At the beginning of the Freeze cycle the inlet water
valve is turned on to fill the reservoir and the cycle
repeats.

Power and Water Interruptions
Short (less than one second) power interruptions
cause no change in operation.
Longer interruptions initiate a restart process:
Freeze light blinks on controller
·
Compressor is off
·
Vapor inlet valve opens
·
Liquid inlet valve closes
·
Purge valve opens
·
Pump starts, empties the reservoir
·
Purge valve closes
·

·
The Compressor starts
·
Vapor inlet valve closes
·
Liquid inlet valve opens
·
Freeze cycle proceeds for 30 seconds
·
Harvest cycle initiated, continues for 4 minutes
·
Normal freeze cycle starts
·
Water Interruptions
The water level sensor checks for water fill
whenever the water inlet valve is activated. If the
water level sensor does not record a full reservoir
within the pre-set time, the controller
shuts the unit off
·
blinks the water diagnostic light two times and
·
repeats
After 20 minutes the inlet water valve is powered
again and if the water level sensor is satisfied, the
unit is restarted. If the controller still doesn’t sense
a full reservoir it keeps the unit off for another 20
minutes and then restarts the water fill process.
The process of retrying water fill will continue until
a full reservoir is sensed. There is no limit to the
number of refill attempts.

Sanitation and Cleaning
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 specifically 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.
In Place Cleaning of the Water System
1. Remove all ice from the bin.
2. Remove the front panel.
3. Push and release the Harvest button (this
releases any ice that may be on the evaporators
and warms them up).
4. Wait for the machine to finish the Harvest cycle
(the machine will stop).
5. Remove the the insulated plastic evaporator
cover, the two inner splash panels (part number
02-3680-01 and the one above it), both cube
deflectors, and the ice sensors. Place the splash
panels and the cube deflectors in a separate
container. Place the ice sensors in the reservoir,
but be sure that the ends of the connecting wires
are not in the water.
6. Push and release the Clean button. The Clean
indicator light will be blinking, and the pump will
restart.
9. After the ice machine cleaner has circulated for
10 minutes, push and release the Clean button.
This starts the rinsing process. The Clean indicator
light will be ON. Note: The rinse process flushes
any residual cleaner out of the ice machine’s water
system.
10. Continue the rinsing process for 20 minutes,
then push the off button to switch the machine off.
11. Go to the next step to sanitize the machine or
go to step 19 to finish the cleaning process.
12. Mix 2 gallons of Sanitizer solution. Follow local
codes for Sanitizer.
Note: A possible sanitizing solution may be made
by mixing 1 ounce of liquid household bleach with
2 gallons of warm (95-115
13. Push and release the Clean button again.
14. Pour 24 ounces of Sanitizer solution into the
reservoir water.
15. After the solution has circulated for 10 minutes
push and release the Clean button. This starts the

Ice Sensor Diagnostics
Diagnostics assume that the control system is
working but may not be able to sense cubes. Its
purpose is to determine which component may be
at fault - the controller or the ice sensors.
Unplug thermostat from terminal 7 of the controller
and check bin full light, if off place an object
between the ice sensors, after 5 seconds the Bin
Full light will be glowing steadily, if not check
operation of sensors by unplugging #4. Bin Full
light will go on after 5 seconds, If not, replace
controller. If the light does go on, replace ice
sensor set.

Water Level Sensor Maintenance
Eclipseä 1300,1600
In most cases the water level sensor will not
require maintenance. However, if the area where
the ice making section is located is dusty or there
is a high concentration of minerals in the water, the
infrared emitter and detector lenses inside the
sensor may need to be wiped off.
1. Remove front panel.
2. Push and hold the Off button until the machine
stops.
3. Unplug sensor wire harness from sensor.
4. Remove two screws holding dust cover to
sensor.
5. Wipe the four lenses with a cotton swap soaked
in potable water.

Water Level Sensor Diagnosis
Clean
Lenses
If it is much less than that, there is something
wrong with either the power supply to the controller
or the controller itself. If the voltage measures
correctly proceed to the next step.
5. Reconnect the harness. Be SURE it is on
properly and has a good connection. To confirm,
unplug the harness from the water sensor and
redo step #4 at the end of the harness. Then plug
the harness back onto the sensor.
Harness Connected Voltage (DC)
6. At the controller, measure the voltage between
the top and bottom pins on connection #2. This
should be between the ranges in the table below. If
it outside this range there is a problem in the
sensor and it should be changed out. If it is within
this range, proceed to the next step.
7. Place negative voltmeter probe on the bottom
terminal (yellow wire). Place the other on the one
just above it (terminate freeze sender - white wire).
Move the float stem/stick up and down and note
the voltage changes. There should be a significant
change between when it is blocked to when it is
not blocked. If there is NO change, the sensor
may be dirty or has failed. Remove the dust cover
from the sensor to clean it.
Note: The sensor must be properly reassembled.
When looking at the terminals of the sensor, they
must be in the lower right corner. If they are in the
upper left remove the sensor’s dust cover and
reverse the board. Later models have an UP arrow
on the right side of the circuit board.
Tools Needed: Digital voltmeter that can read DC
Note: Ambient light can affect this test. Shade the
sensor if needed.
1. Unplug water sensor harness from controller
(connection #2).
2. Confirm that the power to the machine is ON
and that there is at least one light on the board that
is glowing. If not, check the transformer.
3. Set the voltmeter to DC and use a scale low
enough to measure less than 40 Volts.
4. Measure the voltage between the top and the
bottom pins on the controller at connection #2 (the
bottom is ground or negative).
·
Harness unplugged - .5 to 2 VDC

8. With the voltmeter probe still on the bottom
terminal (connection #2), place the other probe on
the second pin from the top (sump full sender - red
wire). Move the float stick up & down, changes in
voltage should be the same as in step 7.
Yellow (bottom)
Red - Blockedabout 5 VDC
