Location Limitations
This ice system is made up of three parts, the ice
making machine, or head; the remote condenser;
and the interconnecting tubing. The ice making
machine must be installed indoors, in a controlled
environment. Space must be provided near the
machine for service access. The remote condenser
may be installed above or below the ice machine,
per the limits stated later in this manual. The
remote condenser may be installed outdoors within
the temperature limits listed below. The
interconnecting tubing must be installed per the
directions stated in this manual, and the amount of
tubing exposed to uncontrolled temperatures must
be minimized.
Space Limitations
Although the machine will function with no
clearance to the top and sides, some space must
be allowed for service access. Building the

Water
C0522 through C1030
Remote Condenser Models - User Manual
The quality of the water supplied to the ice machine
will have an impact on the time between cleanings
and ultimately on the life of the product. Water can
contain impurities either in suspension or in
solution. Suspended solids can be filtered out. In
solution or dissolved solids cannot be filtered, they
must be diluted or treated. Water filters are
recommended to remove suspended solids. Some
filters have treatment in them for suspended solids.
Check with a water treatment service for a
recommendation.
RO water. This machine can be supplied with
Reverse Osmosis water, but the water conductivity
must be no less than 10 microSiemens/cm.
Potential for Airborne Contamination
Installing an ice machine near a source of yeast or
similar material can result in the need for more
frequent sanitation cleanings due to the tendency
of these materials to contaminate the machine.
Most water filters remove chlorine from the water
supply to the machine which contributes to this
situation. Testing has shown that using a filter that
does not remove chlorine, such as the Scotsman
Aqua Patrol, will greatly improve this situation,
while the ice making process itself will remove the
chlorine from the ice, resulting in no taste or odor
impact. Additionally, devices intended to enhance
ice machine sanitation, such as the Scotsman
Aqua Bullet, can be placed in the machine to keep
it cleaner between manual cleanings.
Water Purge
Cube ice machines use more water than what ends
up in the bin as ice. While most water is used
during ice making, a portion is designed to be
drained out every cycle to reduce the amount of
hard water scale in the machine. That’s known as
water purge, and an effective purge can increase
the time between needed water system cleaning.
In addition, this product is designed to
automatically vary the amount of water purged
based on the purity of the water supplied to it. The
water purge rate can also be set manually.
Adjustments of purge due to local water conditions
are not covered by warranty.

Remote Condenser Location
C0522 through C1030
Remote Condenser Models - User Manual
Use the following for planning the placement of the
condenser relative to the ice machine
Location Limits - condenser location must not
exceed ANY of the following limits:
Maximum rise from the ice machine to the
•
condenser is 35 physical feet
Maximum drop from the ice machine to the
•
condenser is 15 physical feet
Physical line set maximum length is 100 feet.
•
Calculated line set length maximum is 150.
•
Calculation Formula:
Drop = dd x 6.6 (dd = distance in feet)
•
Rise = rd x 1.7 (rd = distance in feet)
•
Horizontal Run = hd x 1 (hd = distance in feet)
•
Calculation: Drop(s) + Rise(s) + Horizontal
•
Run = dd+rd+hd = Calculated Line Length
Configurations that do NOT meet these
requirements must receive prior written
authorization from Scotsman.
Do NOT:
Route a line set that rises, then falls, then
•
rises.
Route a line set that falls, then rises, then
•
falls.
Calculation Example 1:
The condenser is to be located 5 feet below the ice
machine and then 20 feet away horizontally.
5 feet x 6.6 = 33. 33 + 20 = 53. This location would
be acceptable
Calculation Example 2:
The condenser is to be located 35 feet above and
then 100 feet away horizontally. 35 x 1.7 = 59.5.
59.5 +100 = 159.5. 159.5 is greater than the 150
maximum and is NOT acceptable.
Operating a machine with an unacceptable
configuration is misuse and will void the
warranty.

Precharged Line Routing
Do not connect the precharged tubing until all
routing and forming of the tubing is complete. See
the Coupling Instructions for final connections.
1. Each set of pre-charged tubing lines contains a
3/8” diameter liquid line, and a 1/2” diameter
discharge line. Both ends of each line have quick
connect couplings, the end without access valves
goes to the ice maker.
Note: The openings in the building ceiling or wall,
listed in the next step, are the minimum sizes
recommended for passing the refrigerant lines
through.
2. Have the roofing contractor cut a minimum hole
for the refrigerant lines of 1 3/4”. Check local
codes, a separate hole may be required for the
electrical power supply to the condenser.
C0522 through C1030
Remote Condenser Models - User Manual
Caution: Do NOT kink the refrigerant tubing while
routing it.
3. Route the refrigerant tubes thru the
roof opening. Follow straight line
routing whenever possible. Excess
tubing may EITHER be coiled up
INSIDE the building OR cut out prior
to connection to the ice maker and
condenser.
If the excess tubing is cut out, after
re-brazing the tubing must be
evacuated prior to connection to the
ice maker or condenser.
If the excess tubing is to be coiled,
spiral it horizontally to avoid excess
trapping in the lines.

Coupling Instructions
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.
2. Lubricate the inside of the couplings, especially
the O-rings, with refrigerant oil.
4b. Then using two wrenches tighten the coupling
until it bottoms out or a definite increase in
resistance is felt.
It is important that ONLY the nut on the
pre-charged tube be turned, or the diaphragms will
be torn out by the piercing knives and they will be
loose in the refrigeration system. Note: As the
couplings are tightened, the diaphragms in the
quick connect couplings will begin to be pierced.
As that happens, there will be some resistance to
tightening the swivel nut.
3. Position the fittings on the correct connections
on the condenser and ice machine.
•
The 1/2" discharge line (schrader valve end)
goes to the remote condenser fitting marked
“discharge line”.
•
The 3/8" liquid line (schrader valve end)
goes to the remote condenser fitting marked
“liquid line”.
•
The 1/2" discharge line goes to the ice maker
fitting marked “discharge line”.
•
The 3/8" liquid line goes to the ice maker
fitting marked “liquid line”.
Final Connections:
4a. Begin by tightening the couplings together by
hand until it is certain that the threads are properly
engaged.
4c. Continue tightening the swivel nut until it
bottoms out or a very definite increase in
resistance is felt (no threads should be showing).
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. Do
NOT over tighten.
6. After all connections have been made, and after
the receiver valve has been opened (do not open
yet), check the couplings for leaks.

Plumbing Requirements
C0522 through C1030
Remote Condenser Models - User Manual
All models require connection to cold, potable
water. A hand actuated valve within site of the
machine is required. There is a single 3/8” FPT
inlet water connection, a 3/8” FPT to 3/8” male flare
adapter is supplied with the machine and can be
used if desired.
Water Filters
Install a new cartridge if the filters were used with a
prior machine.
All models require drain tubing to be attached to
them. There is a single ¾” FPT drain fitting 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 fitting.
Note: This NSF listed model has a 1" anti-back flow
air gap between the potable water inlet tube end
and the highest possible reservoir water level, no
back flow device is required.
2. Connect drain tubing to drain fitting.
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
1. Remove front and left side panels. Check
machine for any packing or wires rubbing
moving parts. Note location of control board in
upper left corner of the machine’s front.
2. Remove tape securing curtain to evaporator.
3. Switch on the electrical power to the machine.
Observe that some of the control’s indicator
lights glow and its display shows O.
4. Wait 4 hours for the compressor’s crankcase
heater to warm up the oil in the compressor.
Start Up
1. Open the water supply valve.
2. Turn the receiver’s outlet valve to the full open
position.
3. Push and release the ON button.
6. When the ice has frozen enough, the Ready for
Harvest indicator light will be on steady. After
it’s been on steady for a few seconds Harvest
will begin.
7. The display shows an H.
The hot gas valve opens and the harvest assist
mechanism is activated. The purge valve opens to
drain some water, when it does the inlet water
valve opens to refill the reservoir. After a few
seconds the purge valve closes but the inlet water
valve continues to fill 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 which 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.
The indicator light will begin to blink F. The purge
valve will open and the water pump will start. The
inlet water valve will open to add water to the
reservoir. After a few seconds the purge valve will
close and the water pump will stop. Water will flow
into the machine until the reservoir is full. The hot
gas valve and harvest assist device will activate
and the liquid line solenoid valve will open, then the
compressor and water pump will start. The display
will show a continuous F. Five seconds later the hot
gas valve will close and the harvest assist device
will return to its standby position. Warm air will be
discharged from the condenser coil.
4. During the Freeze cycle move the curtain 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.
Note: Moving the curtain during the Freeze cycle
has no affect on control function, but will cause
water to flow into the cube chute.
9. Return the panels to their normal positions and
secure them 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.

Optional adjustable ice level control (KVS)
When this option is present there is an adjustment
post and an additional indicator light to the right of
the four indicator lights mentioned above. 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
•
Faster turnover for fresher ice
•
Certain dispenser applications where
•
maximum ice level is not desired

companies. When the board has been remotely
locked out and shut off it must be reset by the
person or company that locked it out. It cannot be
reset on site.
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. When removing ice, tap the groups of
ice with an ice scoop to separate them into smaller
units. In a dispenser, this ice will break up into
mostly individual cubes as the dispense
mechanism moves the ice.
Heat
Most heat is exhausted at the remote condenser.
The ice machine should not generate significant
heat.
Noise
The ice machine will make noise when it is in ice
making mode. The compressor and water pump all
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.

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 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 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.

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 temperature.
•
Controller self test failure.
•
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 flow to it.
2. Has power been shut off to the ice machine? If
yes, the ice machine will automatically restart when
power is restored.
Curtain
3. Has someone shut the power off to the remote
condenser while the ice machine still had power? If
yes, 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.
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 flowing 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.
•
Push and release the Off button.
•
Push and release the On button.
