The ice machine must be protected if it will be
subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing
temperatures is not covered by the warranty. See
“Removal from Service/Winterization”.
B.T.U./Hour
Because the heat of rejection varies during the ice making cycle,
the figure shown is an average.
Ice machines, like other refrigeration equipment, reject
heat through the condenser. It is helpful to know the
amount of heat rejected by the ice machine when sizing
air conditioning equipment where self -c on tained air cooled ice machines are installed.
This information is also necessary when evaluating the
benefits of using water-cooled or remote condensers to
reduce air conditioning loads. The amount of heat added
to an air conditioned environment by an ice machine
using a water-cooled or remote condenser is negligible.
Knowing the amount of heat rejected is also important
when sizing a cooling tower for a water-cooled
condenser. Use the peak figure for sizing the cooling
tower.

Electrical Service
GENERAL
All wiring must conform to local, state and national
codes.
VOLTAGE
The maximum allowable voltage variation is ±1 0% of the
rated voltage at ice machine start-up (when the electrical
load is highest).
The ice machine must be grounded in accordance
with national and local electrical codes.
All electrical work, including wire routing and grounding,
must conform to local, state and national electrical
codes. The following precautions must be observed:
•The ice machine must be grounded.
•A separate fuse/circuit breaker must be provided for
each ice machine.
•A qualified electrician must determine proper wire
size dependent upon location, materials used and
length of run (minimum circuit ampacity can be used
to help select the wire size).
•The maximum allowable voltage variation is +/-10 of
the rated voltage at ice machine start-up (when the
electrical load is highest).
•Check all gre en ground screws in the control box and
verify they are tight before starting the ice machine.
Observe correct polarity of incoming line voltage.
Incorrect polarity can lead to erratic ice machine
operation and a safety issue. This is especially critical o n
230 volt / 50 cycle ice machines.
Fuse/Circuit Breaker
A separate fuse/circuit breaker must be provided for
each ice machine. Circuit breakers must be H.A.C.R.
rated (does not apply in Canada).
MINIMUM CIRCUIT AMPACITY
The minimum circuit ampacity is used to help select the
wire size of the electrical supply. (Minimum circuit
ampacity is not the ice machine’s running amp load.)
The wire size (or gauge) is also dependent upon
location, materials used, length of run, etc., so it must be
determined by a qualified electrician.
ELECTRICAL REQUIREMENTS
Refer to Ice Machine Model/Serial Plate for voltage/
amperage specifications.
GROUND FAULT CIRCUIT INTERUPTER
Ground Fault Circuit Interupter (GFCI/GFI) protection is
a system that shuts down the electric circuit (opens it)
when it senses an unexpected loss of power,
presumably to ground. Manitowoc Ice does not
recommend the use of a GFCI/GFI circuit protection with
our equipment. If code requires the us e of a GF CI /G FI
then you must follow the local code. The circuit must be
dedicated, sized properly and there must be a panel
GFCI/GFI breaker. We do not recommend GFCI/GFI
outlets as they are known for more intermittent nuisance
trips than panel breakers.
MINIMUM POWER CORD SPECIFICATIONS
Maximum
Breaker Size
15 amp14 gauge6 feet (1.83 m)
20 amp12 gauge6 feet (1.83 m)
30 amp10 gauge6 feet (1.83 m)
40 amp8 gauge6 feet 1(.83 m)
If a power cord is used the wire size to the receptacle is
dependant upon location, materials used, length of run, etc., so
it must be determined by a qualified electrician. Local, state or
national requirements will supersede our minimum
requirements.

Caution
Water Supply and Drain Requirements
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
If you are installing a Manitowoc Arctic Pure water
filter system, refer to the Installation Instructions
supplied with the filter system for ice making water
inlet connections.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
•Do not connect the ice machine to a hot water
supply. Be sure all hot water restrictors installed for
other equipment are working. (Check valves on sink
faucets, dishwashers, etc.)
•If water pressure exceeds the maximum
recommended pressure (80 psi), obtain a water
pressure regulator from your Manitowoc distributor.
•Contact your distributor if your water pressure is
greater than 150 psig (10.34 bar). A special order
condensing unit is available that allows water
pressure up to 350 psig (24.13 bar).
•Install a water shut-off valve for both the ice making
and condenser water lines.
•Insulate water inlet lines to prevent condensation.
Do not apply heat to water valve inlet fitting. This will
damage plastic water inlet connection.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to
prevent drain water from flowing back into the ice
machine and storage bin:
•Drain lines must have a 1.5 inch drop per 5 feet of
run (2.5 cm per meter), and must not create traps.
•The floor drain must be large enough to
accommodate drainage from all drains.
•Run separate bin and ice machine drain lines.
Insulate them to prevent condensatio n.
•Vent the bin and ice machine drain to the
atmosphere. Do not vent the condenser drain on
water-cooled models.
•S3300 requires base drain connection (1” FPT).
Cooling Tower Applications
(Water-Cooled Models)
A water cooling tower installation does not require
modification of the ice machine. The water regulator
valve for the condenser continues to control the
refrigeration discharge pressure.
It is necessary to know the amount of heat rejectio n, and
the pressure drop through the condenser and water
valves (inlet and outlet) when using a cooling tower on
an ice machine.
•Water entering the condenser must not exceed
90°F (32.2°C).
•Water flow through the condenser must not exceed
5 gallons (19 liters) per minute.
•Allow for a pressure drop of 7 psi (0.5 bar) between
the condenser water inlet and the outlet of the ice
machine.
•Water exiting the condenser must not exceed
110°F (43.3°C).
S3300 CONDENSER WATER PRESSURE
Water pressure at the condenser cannot exceed 150
psig (10.34 bar) with the standard water-regulating
valve. Contact your distributor if your water pressure is
greater than 150 psig (10.34 bar). A special order
condensing unit is available that allows water pressure
up to 350 psig (24.13 bar).
IMPORTANT
The Commonwealth of Massachusetts requires that all
water-cooled models must be connected only to a closed
loop, cooling tower system.

GENERAL
Condensers must be mounted horizontally with the fan
motor on top with nothing obstructing it. There must be
at least a 16” clearance from the bottom for air intake.
The front coupling panel & one other panel (back or
side) must also be unobstructed.
Remote condenser installations consist of vertical and
horizontal line sets between the ice machine and the
condenser. When co mbined, they must fit within
approved specifications. The following guidelines,
drawings and calculation methods must be followed to
verify a proper remote condenser installation.
The 60 month compressor warranty (including the
36 month labor replacement warranty) will not apply
if the remote ice machine is not installed according
to specifications.
This warranty also will not apply if the refrigeration
system is modified with a condenser, heat reclaim
device, or other parts or assemblies not
manufactured by Manitowoc Ice unless specifically
approved in writing by Manitoc Ice.
The maximum length is 100' (30.5 m).
The ice machine compressor must have the proper oil
return. The receiver is designed to hold a char ge
sufficient to operate the ice machine in ambient
temperatures between -20°F (-29°C) and 120°F (49°C),
with line set lengths of up to 100' (30.5 m).
Line Set Rise/Drop
The maximum rise is 35' (10.7 m).
The maximum drop is 15' (4.5 m).
If a line set has a rise followed by a drop, another
rise cannot be made. Likewise, if a line set has a
drop followed by a rise, another drop cannot be
made.
Calculated Line Set Distance
The maximum calculated distance is 150' (45.7 m).
Line set rises, drops, horizontal ru ns (or combinations of
these) in excess of the stated maximums will exceed
compressor start-up and design limits. This will cause
poor oil return to the compressor.
Make the following calculations to make sure the line set
layout is within specifications.
1. Insert the measured rise into the formula below.
Multiply by 1.7 to get the calculated rise.
(Example: A condenser located 10 feet above the
ice machine has a calculated rise of 17 feet.00)
2. Insert the measured drop into the formula below.
Multiply by 6.6 to get the calculated drop.
(Example. A condenser located 10 feet below the
ice machine has a calculated drop of 66 feet.)
3. Insert the measured horizontal distance into the
formula below. No calculation is necessary.
4. Add together the calculated rise, calculated drop,
and horizont al distance to get the total calculated distance. If this total exceeds 150' (45.7 m), move
the condenser to a new location and perform the
calculations again.

LENGTHENING OR REDUCING LINE SET LENGTHS
In most cases, by routing the line set properly,
shortening will not be necessary. When shortening or
lengthening is required, do so before connecting the line
set to the ice machine or the remote condenser. This
prevents the loss of refrigerant in the ice machine or
condenser.
The quick connect fittings on the line sets are equipped
with Schraeder valves. Use these valves to recover any
vapor charge from the line set. When lengthening or
shortening lines follow good refrigeration practices,
purge with nitrogen and insulate all tubing. Do not
change the tube sizes. Evacuate the lines and place
about 5 oz (143g) of vapor refrigerant charge in each
line.
CONNECTING A LINE SET
1. Remove the dust caps from the line set, condenser
and ice machine.
2. Apply refrigeration oil to the threads on the quick
disconnect couplers before connecting them to the
condenser.
3. Carefully thread the female fitting to the condenser
or ice machine by hand.
4. Tighten the couplings with a wrench until they
bottom out.

The receiver service valve is closed during shipment.
Open the valve prior to starting the ice machine.
1. Remove the top and left side panels.
2. Remove the receiver service valve cap.
3. Backseat (open) the valve.

FAN MOTOR
The condenser fan must be on during the complete ice
machine freeze cycle (do not cycle on fan cycle control).
The ice maker has a condenser fan motor circui t fo r use
with a Manitowoc condenser . It is recommended that this
circuit be used to control the condenser fan(s) on the
multi-circuit condenser to assure it is on at the proper
time. Do not exceed the rated amp s for the fan motor
circuit listed on the ice machine’s serial tag.
INTERNAL CONDENSER VOLUME
The multi-circuit condenser internal volume must not be
less than or exceed that used by Manitowoc (see chart
on next page). Do not exceed internal volu me and tr y
to add charge to compensate, as compressor fa ilure
will result.
CONDENSER T
T is the difference in temperature between the
condensing refrigerant and entering air. The T should
be 15 to 20°F (-9.4 to -6.6°C) at the beginning of the
freeze cycle (peak load conditions) and drop down to 12
to 17°F (-11.1 to -8.3°C) during the last 75% of the
freeze cycle (average load conditions).
REFRIGERANT CHARGE
Remote ice machines have the serial plate refrigerant
charge (total system charge) located in the ice maker
section. (Remote condensers and line sets are supplied
with only a vapor charge.)
Never add more than nameplate charge to ice

Sequence Of Operation
NOTE: The toggle switch must be in the ice position and
the water curtain/ice dampers must be in place on the
evaporator before the ice machine will start.
INITIAL START-UP OR START-UP AFTER
AUTOMATIC SHUT-OFF
1. Water Purge
Before the refrigerant compressor st arts, the water pump
and water dump solenoid energize to purge the ice
machine of old water. This feature ensures that the ice
making cycle starts with fresh water.
Single evaporator models energize the harvest valve(s)
and air compressor (when used) at the en d of the wate r
purge and they remain energized during refrigeration
startup.
2. Refrigeration System Start-Up
The compressor, condenser fan motor and water fill
valve energize and 5 seconds later the harvest valve(s)
and air compressor(s) de-energize.
The fan motor is wired through a fan cycle pressure
control and will cycle on and off when the room
temperatures is below 70 F (21 C) .
FREEZE SEQUENCE
3. Prechill
The compressor lowers the temperature of the
evaporator(s) before the water pump is energized. The
water fill valve will remain energized until water contacts
the water level probe.
4. Freeze
The water pump(s) energizes and water flows over the
evaporator. After water contacts the water level probe
the water fill valve de-energizes. The water fill valve will
cycle on and off one more time.
The freeze cycle continues until the six minute freeze
lock expires and enough ice has formed to allow water to
contact the ice thickness probe. After approximately 10
seconds of continual water contact, the harvest
sequence is initiated.
NOTE: Freeze lock is bypassed after moving the toggle
switch from OFF to ICE position for the first cycle only.
HARVEST SEQUENCE
5. Water Purge
The air compressor (when used) and the harvest
valve(s) open at the beginning of the water purge to
divert hot refrigerant gas into the evaporator.
The water pump continues to run, and the water dump
valve energizes to purge the water in the water trough.
Single evaporator models energize the water fill valve for
the last 15 seconds of the water purge cycle.
6. Harvest
The air compressor (when used) remains energized and
the harvest valve(s) remains open. The refrigerant gas
warms the evaporator causing the cubes to slide, as a
sheet, off the evaporator and into the storage bin.
Single evaporator models - The sliding sheet of cubes
opens the water curtain and bin switch.
The momentary opening and re-closing of the bin switch
terminates the harvest sequence and return to the
freeze sequence (Step 3 - 4.)
Multiple evaporator models - The sliding sheet of
cubes opens the ice damper and bin switch. The
momentary opening and re-closing of the bin switch deenergized the harvest valve for the evaporator. When all
of the bin switches have opened and closed the ice
machine will terminate the harvest sequence and return
to the freeze sequence (Step 3 - 4.)
AUTOMATIC SHUT-OFF
7. Automati c Sh ut -O ff
When the storage bin is full at the end of a harvest
sequence, the sheet of cubes fails to clear the water
curtain/ice damper and will hold it open. After the water
curtain/ice damper is held open for 30 seconds, the ice
machine shuts off. The ice machine remains off for 3
minutes before it can automatically restart.
The ice machine remains off until enough ice has been
removed from the storage bin to allow the ice to fall clear
of the water curtain or all of the ice dampers. As the
water curtain/ice dampers swing back to the closed
position, the bin switch re-closes and the ice machine
restarts (steps 1 - 2), provided the 3 min ute delay period
is complete.

SAFETY TIMERS
The control board has the following non-adjustable
safety timers:
•The ice machine is locked into the freeze cycle for 6
minutes before a harvest cycle can be initiated.
Freeze lock is bypassed after moving the toggle
switch from OFF to ICE position for the first cycle
only .
•The maximu m freeze time is 60 minutes at which
time the control board automatically initiates a
harvest sequence (steps 5 & 6).
•The maximum harvest time is 3.5 minutes for single
evaporators and 7 minutes for multiple evaporator
model. The control board automatically initiates a
freeze sequence (steps 3 & 4) when these times are
exceeded.
SAFETY LIMITS
Safety limits are stored and indicated by the control
board after three cycles. The number of cycles required
to stop the ice machine varies for each safety limit.
•Safety Limit 1 - If the freeze time reaches 60 minutes,
the control board automatically initiates a harvest
cycle. If 6 consecutive 60-minute freeze cycles occur,
the ice machine stops
WARM WA TER RINSE CYCLE
Single evaporator models only - Closing the back of the
evaporator allows ice to build up on the rear of the
evaporator and the plastic evaporator frame parts. After
200 freeze/harvest cycles have been completed the
control board will initiate a warm water rinse.
After the 200th harvest cycle ends:
•The Clean and Harvest LED’s energize to indicate
the ice machine is in a warm water rinse.
•The compressor and harvest valve remain
energized.
•The water pump energizes.
•The water inlet valve energizes until water contacts
the water level probe.
•The compressor and harvest valve warm the water
for 5 minutes, then de-energize.
•The water pump remains energized for an additional
5 minutes (10 minute total on time) then deenergizes.
NOTE:
moving the toggle switch to the OFF position, then back to ICE.
The warm water rinse cycle can be terminated by
•Safety Limit 2 single evaporator models - If the
harvest time reaches 3.5 minutes, the control board
automatically returns the ice machine to the freeze
cycle. If threeIf 500 consecutive 3.5 minute harvest
cycles occur, the ice machine stops.
•Safety Limit 2 multiple evapora tor models - If the
harvest time reaches 7 minutes, the control board
automatically returns the ice machine to the freeze
cycle. If 500 consecutive 7 minute harvest cycles
occur, the ice machine stops.
•Safety Limit 3 multiple evapor ator models - If the low
refrigerant pressure control opens, the ice machine
shuts off and starts a 5 minute delay period. If 3
consecutive low pressure events occur the ice
machine stops and flashes the safety/harvest light.
Use the following procedures to determine if the control
board contains a safety limit indication.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ICE. Watch the
safety limit lights on the control board. If a safety
limit has been recorded, the corresponding light will
blink once, twice or three times to indicate which
safety limit stopped the ice machine.

Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally, new installations do
not require any adjustment.
To ensure proper operation, always follow the
Operational Checks:
•when starting the ice machine for the first time
•after a prolonged out of service period
•after cleaning and sanitizing
NOTE: Routine adjustments and maintenanc e
procedures are not covered by the warranty.
WATER LEVEL
The water level sensor is set to maintain the proper
water level above the water pump housing. The water
level is not adjustable. If the water level is incorrect,
check the water level probe for damage (probe bent,
etc.). Clean the water level probe with ice machine
cleaner, rinse thoroughly and re-check opera tion. Repair
or replace the probe as necessary.
ICE THICKNESS CHECK
The ice thickness probe is factory-set to maintain th e ice
bridge thickness at 1/8" (.32 cm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing
out of the water trough.
1. Inspect the bridge connecting the cubes. It should
be about 1/8" (.32 cm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness, counterclockwise to decrease
bridge thickness. Set at 1/4” gap between ice
machine and evaporator as starting point, then
adjust to achieve a 1/8” bridge thickness.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16" (1.5 mm).

HARVEST SEQUENCE WATER PURGE
The harvest sequence water purge adjustment may be
used when the ice machine is hooked up to special
water systems, such as a de-ionized water treatment
system.
Disconnect electric power to the ice machine at the
electrical disconnect before proceeding.
The harvest sequence water purg e is factory-set at
45 seconds. A shorter purge setting (with standard
water supplies such as city water) is not
recommended. This can increase water system
cleaning and sanitizing requirements.
•The harvest sequence water purge is factory set.
Repositioning the jumper will set the harvest water
purge to 0 seconds. This setting does not affect the
SeCs or AuCs (cleaning) sequences.
•During the harvest sequence water purge, the water
fill valve energizes and de-energizes by time. The
water purge must be at the factory setting of 45
seconds for the water fill valve to energize during the
last 15 seconds of the water purge. If it is set to less
than 45 seconds, the water fill valve will not energize
during the water purge.
Water Purge Adjustment
For your safety and to eliminate errors, we recommend
that a qualified service technician make the harvest
water purge adjustment.

Manitowoc’s Cleaning Technology
Manitowoc Ice Machines include technology that allows
the initiation and completion of a cleaning cycle at the
flip of a switch. This cycle will permit cleaning of all
surfaces that come in contact with the water distribution
system. Periodic maintenance must be performed that
includes sanitizing the bin and adjacent surface areas,
which are not contacted by the water distribution system.
Depending on local water conditions Manitowoc
recommends initiating preventative maintenance
cleaning procedures between the 6 month cleanings.
This preventive maintenance removes mi n era l build -u p
from the evaporator, which results in peak efficiency and
lower operating costs.
This technology allows initiation and completion of a
clean cycle, after which the ice machine automatically
starts ice making again.
Manitowoc recommends disassembling, cleaning and
sanitizing the ice machine and dispenser every six
months
This Manitowoc Ice Machine has two separate cleaning
procedures.
Cleaning/Sanitizing Procedure
This procedure must be performed a minimum of once
every six months.
•The ice machin e and bin must be disassembled
cleaned and sanitized
•All ice produced during the cleaning and sanitizing
procedures must be discarded
•Removes mineral deposits from areas or surfaces
that are in direct contact with water
Heavily Scaled Cleaning Procedure
Perform this procedure if you have some or all of these
symptoms.
•Ice machine stops on Safety Shutdown
•Your water has a high concentration of minerals
•The ice machin e has not been on a regular
maintenance schedule.

Ice Machine Inspection
Check all water fittings and lines for leaks. Also, make
sure the refrigeration tubing is not rubbing or vibrating
against other tubing, panels, etc.
Do not put anything (boxes, etc.) on the sides or back of
the ice machine. There must be adequate airflow
through and around the ice machine to maximize ice
production and ensure long component life.
Exterior Cleaning
Clean the area around the ice machine as often as
necessary to maintain cleanliness and efficient
operation. Use cleaners designed for use with stainless
steel products.
Sponge any dust and dirt off the outside of the ice
machine with mild soap and water. Wipe dry with a
clean, soft cloth.
Heavy stains should be removed with stainless steel
wool. Never use plain steel wool or abrasive pads. They
will scratch the panels.
Cleaning the Condenser
GENERAL
Disconnect electric power to the ice machine head
section and the remote condensing unit at the
electric service switches before cleaning the
condenser.
A dirty condenser restricts airflow, resulting in
excessively high operating temperatures. This reduces
ice production and shortens component life. Clean the
condenser at least every six months. Follow the steps
below.
The condenser fins are sharp. Use care when
cleaning them.
1. The washable aluminum filter on self-contained ice
machines is designed to catch dust dirt lint and
grease. Clean the filter with a mild soap and water.
2. Clean the outside of the condenser with a soft brush
or a vacuum with a brush attachment. Be careful not
to bend the condenser fins.
3. Shine a flashlight through the condenser to check
for dirt between the fins. If dirt remains:
A. Blow compressed air through the condenser fins
from the inside. Be careful not to bend the fan
blades.
B. Use a commercial condenser coil cleaner.
Follow the directions and cautions supplied with
the cleaner.

blades are excessively dirty, wash with warm, soapy
water and rinse thoroughly.
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water damage
and disconnect electrical power.
Water-Cooled Condenser and Water
Regulating Valve
Symptoms of restrictions in the condenser water circu it
include:
•Low ice production
•High water consumption
•High operating temperatures
•High operating pressures
If the ice machine is experiencing any of these symptoms,
the water-cooled condenser and water regulating valve
may require cleaning due to scale build-up.
Because the cleaning procedures require special pump s
and cleaning solutions, qualified maintenance or service
personnel must perform them.
AlphaSan
The goal of AlphaSan is to keep the plastic surfaces of
an ice machine cleaner, by reducing or delaying the
formation of bio-film. The active ingredient in Alph a San
is the element silver in the form of silver ions (Ag+).
AlphaSan slowly releases silver ions via an ion
exchange mechanism. When AlphaSan is compounded
directly into a plastic part, a controlled release of silver
ions from the surface is regulated to maintain an
effective concentration at or near the surface of the
plastic ice machine part. AlphaSan’s unique ability to
effectively control the release of silver not only protects
against undesired discoloration of the plastic, but also
will last the life of the plastic part. Although AlphaSan
helps prevent bio-film build up it does not eliminate the
need for periodic cleaning and maintenance. AlphaSan
has no adverse effect on the taste of the ice or
beverage.

Slime is a leading cause of ice machine breakdowns and
biological growth is a health concern. The Guardian
system releases chlorine dioxide on a controlled basis to
inhibit the growth of bacteria and fungi that form slime
and cause malodors in the food zone of ice machines.
The Guardian will not control mineral or other water
borne buildup. Your water quality will determine the
length of time before mineral buildup af fects ice machine
performance. Mineral buildup must be removed as of ten
as necessary to ensure trouble-free operation of the ice
machine.
