Electrical Service
QF0406A 230/50/1 ice machines are factory pre-wired
with a power cord, no plug is supplied.
All wiring must conform to local, state and national
codes.
VOLTAGE
The maximum allowable voltage variation is ±1 0% of the
rated voltage on the ice machine model/serial number
plate at start-up (when the electrical load is highest).
GROUND FAULT INTERRUPTER CIRCUIT (GFIC)
Ground Fault Circuit Interrupter protection is a system
that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to
ground. Manitowoc does not recommend the use of a
GFCI/GFI circuit protection with our equipment. If code
requires the use of a GFCI/GFI 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.
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).
The ice machine must be grounded in accordance
with national and local electrical codes.
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the wire
size of the electrical supply.
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.

POTABLE WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
POTABLE 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 (80 psig/
551.5 kPA) recommended pressure, obtain a water
pressure regulator from your Manitowoc distributor.
• Install a water shut-off valve and union for both the
ice making and condenser water lines.
• Insulate water inlet lines to prevent condensation.
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 water-cooled condenser drain
lines. Insulate them to prevent condensation.
• Vent the bin and ice machine drain to the
atmosphere. The ice machine drain requires an 18”
vent. Do not vent the condenser drain on watercooled models.
• Drains must have a union or other suitable means to
allow in place disconnection from the ice machine
when servicing is required.

Sequence of Operation
Section 3
Operation
PRIOR TO START-UP
When the toggle switch is placed in the “ice” position the
following must occur prior to starting an ice making
cycle.
A. The bin level probe must be open (bin level
light off). If the probe is closed, (bin level light
on) when the toggle switch is moved to ICE, the
control system waits until the bin level probe
opens, (bin level light off) before starting an ice
making sequence. If the bin level probe is
removed/disconnected the ice machine will not
start.
B. The water level probe must be closed (water
level light on) to start the compressor. If the
water level probe is open (water level light off),
the control system waits until the water level
probe closes before starting the compressor.
INITIAL START-UP
1. Flush
Immediately after placing the toggle switch into ICE, the
gearbox energizes. After 45 seconds the water float
valve solenoid is energized.
2. Freeze Cycle
When water contacts the water level probe, the
compressor and condenser fan motor energize
(condenser fan motor is wired through a fan cycling
control).
AUTOMATIC SHUT-OFF
3. Ice Run Out
Ice will build up in the bin until it contacts the bin level
probe. After ice contacts the bin level probe for 30
continuous seconds the compressor de-energizes. To
allow excess ice to run out, the gear motor and th e water
float valve solenoid remain energized for an additional
45 seconds, then de-energize.
A 8-minute lockout starts when the compressor deenergizes. When the ice drops away from the bin level
probe the ice machine will begin an initial start-up cycle,
provided the “8-minute lockout” has expired.
8 MINUTE LOCKOUT
The bin level light will flash until the 8-minute lockout
expires.
After the 8 minute lockout expires the bin level light will
de-energize.
The 8 minute lockout time can be overridden by moving
the ON/OFF/CLEAN toggle switch from ICE to OFF then
back to ICE.
SAFEGUARD FEATURE
In addition to standard safety controls, your Manitowoc
ice machine features built-in SafeGuards. The ice
machine will stop when conditions arise that would
cause major component failure. Refer to Section 5 for
full details.
The gear motor, compressor, condenser fan motor and
water float valve solenoid remain energized as the ice
machine makes ice. The water float valve will open and
close automatically to maintain the proper water level.
Part Number 000007651 05/10 9
Flake ice machines use an auger to remove ice from the
evaporator . Occasional noises ( creaks, groans, or p ops)
are a normal part of the ice making process.

Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally , a newly inst alled ice
machine does 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 outlined in this manual are not covered by
the warranty.
WATER LEVEL CHECK
The float valve maintains the correct water level. The
water level must allow the water level probes to maintain
water contact throughout the freeze cycle. The water
level is factory set and normally will not require
adjustment. Check the water level during the freeze
cycle. The water level is correct if the water level
indicator light is energized (compressor is running) and
no water is entering the overflow tube. (Check for
overflow water exiting the ice machine drain line at the
floor drain.)
If adjustments are necessary:
A. Rotate float clockwise to increase water level
.
B. Rotate float counterclockwise to decrease water
level.
C. Verify the outlet for the water float valve is at a
20 to 30 degree angle to prevent contact with
the float.

only products approved for use in Manitowoc ice
machines.
Use only Manitowoc approved Ice Machine Cleaner
(part number 000000084) and Sanitizer (part
number 94-0565-3). It is a violation of Federal law to
use these solutions in a manner inconsistent with
their labeling. Read and understand all labels
printed on bottles before use.
Do not mix Cleaner and Sanitizer solutions together.
It is a violation of Federal law to use these solutions
in a manner inconsistent with their labeling.
Wear rubber gloves and safety goggles ( an d/or face
shield) when handling Ice Machine Cleaner or
Sanitizer.
Manitowoc Ice Machines have three separate
cleaning procedures.
Preventative Maintenance Cleaning Procedure
Perform this procedure as required for your water
conditions.
• Allows cleaning the ice machine without removing all
of the ice from the bin
• Removes mineral deposits from areas or surfaces
that are in direct contact with water during the freeze
cycle (reservoir, evaporator, auger, drain lines).
Cleaning/Sanitizing Procedure
This procedure must be performed a minimum of once
every six months.
• All ice must be removed from the bin
• The ice machine and bin must be disassembled
cleaned and sanitized
• The ice machine produces ice with the cleaner and
sanitizer solutions
• All ice produced during the cleaning and sanitizing
procedure must be discarded
Heavily Scaled Cleaning Procedure
Perform this procedure if you have some or all of these
symptoms.
• Grinding, popping or squealing noises from the
evaporator
• Grinding noise from gearbox
• Ice machine trips speed sensor
NOTE: A Cleaning/Sanitizing Procedure must be
performed after this procedure.
EXTERIOR CLEANING
Remove dust and dirt off exterior surfaces with mild
household dish-washing detergent and warm water.
Wipe dry with a clean, soft cloth.
Part Number 000007651 05/10 11
Maintenance Section 4
MANITOWOC’S CLEANING TECHNOLOGY
Manitowoc Flake Ice Machines include technology that allows the initiation and completion of a cleaning or sanitizing
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 wate r 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 fr om the evaporator, which results in peak efficiency and
lower operating costs.
This technology will also allow initiation and completion of a clean or sanitize cycle, after which the ice machine
automatically starts ice making again.
Refer to the cleaning/sanitizing procedure for complete details.
PREVENTATIVE MAINTENANCE CLEANING PROCEDURE
Use Ice machine cleaner part number 000000084 only.
This cleaner is used to remove lime scale or other
mineral deposits. It is not used to remove algae or slime.
Refer to “Cleaning/Sanitizing Procedure” for removal of
algae and slime. To initiate a cleaning cycle using
Manitowoc’s Cleaning Technology use the following
procedure.
Step 1 Set the toggle switch to the OFF position. Open
the bin door and remove the 2 thumbscrews and white
plastic panel.
Step 2 Disconnect the water inlet line by depressing
the stainless steel tab (refer to disassembly for cleaning
for procedure).
Step 3 Move the toggle switch to the CLEAN position.
Water will flow through the water dump valve and down
the drain. The flush, gear motor, speed, dump valve and
water solenoid lights will energize to indicate the ice
machine is in the clean mode.
Step 4 Wait about one minute or until the dump valve
de-energizes. Lift the front cover on the water reservoir
and add the proper amount of Manitowoc Ice Machine
Cleaner.
Step 5 Reconnect the water inlet line by pushing onto
fitting and snapping into locked position.
Step 6 The ice machine will automatically time out
flush and rinse cycles, and then stop. The flush light
remains energized until the toggle switch is moved to the
OFF position. This entire cycle lasts approximately 11
minutes.
Step 7 Replace the white plastic panel and move the
toggle switch to the ice position.
NOTE: Periodic cleaning must be performed on adjacent
surface areas not contacted by the water distribution
system.
Manitowoc recommends disassembling, cleaning and
sanitizing the ice machine and bin/dispenser ev er y six
months.
NOTE: The ice machine may be set to start and finish a
cleaning procedure, and then automatically start ice
making again. Wait about one minute into the cleaning
cycle (until the dump valve light de-energizes), then
move the switch from CLEAN to ICE position. When the
clean cycle is complete ice making starts automatically.
