Installation: Product Specifications
Location Limitations: The product is designed to be
installed indoors, in a controlled environment. Air
cooled models discharge very warm air into the
room out the back. Space must be allowed at the
left side and back for air intake and discharge.
Water cooled models discharge warm water into
the building’s drain. Space needs to be provided on
both sides and above for service access.
Space Limitations
Note: Although the machine will function, ice
capacity of air cooled machines will be significantly
reduced with minimal clearance at the sides, back
and top. Some space is recommended for service
and maintenance purposes on all models.
6" of space at the sides and back are required for
adequate operation. To get the most capacity,
locate the machine away from heat producing
appliances and heating ducts. Provide several feet
of space to the left for maximum ice capacity.
Walls or other large machines near to the ice
machine might also cause a reduction in ice
capacity. One foot behind and two feet above will
be required to make rated capacity.

C1448, C1848, C2148W
Air and Water Cooled 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. There are
two ways water can contain impurities: 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.
Scotsman filters:
A triple head filter is recommended for the potable
water. Either the Scotsman SSM3 taste and odor
filter system, or the ADS-AP3 Aqua Patrol system.
RO water. This machine can be supplied with
Reverse Osmosis water, but the water conductivity
must be no less than 10 microSiemens/cm.
Condenser Water Supply - filtration not
recommended for this water supply
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 flush, and an effective flush can increase the
time between needed water system cleaning.
In addition, this product is designed to
automatically vary the amount of water flushed
based on the purity of the water supplied to it. The
water flush rate can also be set manually.
Adjustments of flush due to local water conditions
are not covered by warranty.

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

Begin with unpacking the ice storage bin. Remove
the carton, and using part of the carton as a
cushion, tip the bin on its back to remove the skid
and attach the legs or casters.
Note: Turn the leg levelers in all the way and adjust
after the ice machine is on top and in its selected
location.
Return the bin to an upright position. Check the bin
top gasket for gaps and tears, fill any in with food
grade sealant prior to placing the ice machine on
the bin.
Install the bin top adapter if one is required for the
application.
If the ice machine has not been unpacked, do so
now. Remove the carton from the skid. Lift the ice
machine off the skid directly onto the bin.
Note: The machine is heavy! Use a mechanical
hoist if necessary.
Bin Recycling
Many times an ice machine head will be replaced,
while the existing ice storage bin will be reused.
This is an acceptable practice, if some precautions
are taken:
The used bin must be in good condition.
•
Broken doors, hinges, or warped walls are
reason for considering a new bin.
The used bin top edge gasket must be
•
replaced. Water leaks could occur if the
gasket tape is not replaced.
The used bin should be the proper size for
•
the ice machine head.
Secure the ice machine to the bin with the
hardware provided (two metal straps and 4 bolts).
Level the bin and ice machine using the adjustment
part of the legs.

Plumbing Requirements
All models require connection to cold, potable
water. A hand actuated valve within site of the
machine is required. Air cooled models have 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 Fitting
Inlet Water
Connection
Water cooled models have the same inlet fitting
plus an additional 3/8” FPT condenser inlet water
connection.
Water Filters
If connecting to water filtration, filter only the water
to the reservoir, not to the condenser. Install new
cartridges if the filters were used with a prior
machine.
A triple head filter is recommended. Either the
Scotsman SSM3 taste and odor filter system, or
the ADS-AP3 Aqua Patrol system.

All models require drain tubing to be attached to
them. Air cooled models have a single ¾” FPT
drain fitting in the back of the cabinet. Water cooled
models have the same fitting plus an additional ½”
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 fittings.
Note: This NSF listed model has a 1" anti-back flow
air gap between the end of the water inlet tube and
the highest possible reservoir water level, no back
flow device is required for the potable water inlet.
2 Connect drain tubing to drain fittings.

Connection
3 Route the drain tubing to building drain. Follow
local codes for air gap.
Use rigid drain tubes and then route them
separately – do not Tee into the bin’s drain or, if
water cooled, Tee the condenser drain into the
reservoir or bin 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 panel. 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 each curtain to its
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 Open the water supply valve.
5 Push and release the ON button. The indicator
light will begin to blink F.
The flush 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 flush valve
will close and the water pump will stop. Water will
flow into the machine until the reservoir is full. The
hot gas valves and harvest assist devices will
activate then the compressor and water pump will
start. If its an air cooled model the fan(s) motors
will begin to turn. The display will show a
continuous F. Five seconds later the hot gas valves
will close and the harvest assist device will return
to its standby position. Warm air will be discharged
from air cooled models.
6 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 first 6
minutes of freeze.
7 During the Freeze cycle open and close the
curtains. The SW1 and SW2 lights on the
control board will blink ON when each curtain is
opened and OFF when closed.
Note: Moving a curtain during the Freeze cycle has
no affect on the control, but will cause water to flow
into the cube chute.
The hot gas valves open, the air cooled fan motors
shut off and the harvest assist mechanisms are
activated. The flush valve opens to drain some
water, when it does the inlet water valve opens to
refill the reservoir. After a few seconds the flush
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 both curtains re-close the controller returns
the unit to a freeze cycle.
10 Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 3/16
inch. If needed, adjust bridge thickness. Do
NOT make it too thin.
11 Determine the water flush setting from the table
below. If desired, change the setting to
accommodate the local water conditions.
12 Return the front panel to its normal position
and secure it to the machine.
13 Instruct the user in the operation of the
machine and its maintenance requirements.
14 Fill out and mail warranty registration form.

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
Air cooled models will generate heat when in
operation. That heat is discharged out the back of
the cabinet.
Noise
The ice machine will make noise when it is in ice
making mode. The compressor, fan motors if air
cooled 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.

•
Clean or replace the air filter 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 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.

completes the Harvest cycle it will stop. If the
bin is full (b shows in display) push and release
the Off button.
4 Remove all ice from the storage bin or
dispenser.
5 Push and release the Clean button. The yellow
Clean light will blink and the display will show
C. The machine will drain the reservoir and refill
it. Go onto the next step when the reservoir has

Air cooled condenser filter
1 Pull air filters from their louvered mounts.
2 Wash the dust and grease off the filter.
3 Return them to their original positions.
Do not operate the machine without the filter in
place except during cleaning.
Maintenance
Air cooled condenser
If the machine has been operated without a filter
the air cooled condenser fins will need to be
cleaned.
Push and release the Off button. Wait until the
machine stops.
If there is imbedded grease, use a commercial coil
cleaner to wash out the grease. Dust can be blown
out with compressed air from the back with a
vacuum cleaner operating in the fan area. Be
careful not to damage the condenser’s fins. Use a
fin comb to straighten any bent fins.
Exterior Panels
The front and side panels are durable stainless
steel. Fingerprints, dust and grease will require
cleaning with a good quality stainless steel cleaner.
Filter
Air Filter Removal
Filter
Water filters
If the machine has been connected to water filters,
check the cartridges for the date they were
replaced or for the pressure on the gauge. Change
cartridges if they’ve been installed more than x
months or if the pressure drops too much when the
ice machine fills with water.

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.
C1448, C1848, C2148W
Air and Water Cooled User Manual
3. Has someone shut the water off to a water
cooled unit? 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. 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.
To Shut the Machine Off:
1. Push and hold the Off button for 3 seconds or
until the machine stops.
