Installation Instructions	Section 2

Electrical Service

! Warning

All wiring must conform to local, state and national codes.

VOLTAGE

The maximum allowable voltage variation is ±10% 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).

QF0406A 115/60/1 ice machines are factory pre-wired with a power cord and 5-15P plug confirmation.

For United Kingdom Only

QF0406A 230/50/1 ice machines are factory pre-wired with a power cord, no plug is supplied.

! Warning

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.

Electrical Requirements

Maximum Fuse Size

	Ice Machine	Voltage	Maximum	Total

Section 2	Installation Instructions

Water Supply and Drains

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.

Section 3

Operation

Sequence of 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).

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.

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 the 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.

Flake ice machines use an auger to remove ice from the evaporator. Occasional noises (creaks, groans, or pops) are a normal part of the ice making process.

Operation	Section 3

Operational Checks

GENERAL

Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, a newly installed 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 maintenance 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.

Maintenance

Interior Cleaning and Sanitizing

GENERAL

You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty.

Clean and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent cleaning and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment. An extremely dirty ice machine must be taken apart for cleaning and sanitizing.

Manitowoc Ice Machine Cleaner and Sanitizer are the only products approved for use in Manitowoc ice machines.

! Caution

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.

! Caution

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.

! Warning

Wear rubber gloves and safety goggles (and/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.

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 water distribution system.

Depending on local water conditions Manitowoc recommends initiating preventative maintenance cleaning procedures between the 6 month cleanings.

This preventive maintenance removes mineral build-up from 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 every 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.

CLEANING/SANITIZING PROCEDURE

Use Ice machine cleaner part number 000000084. Use Ice machine sanitizer part number 94-0565-3.

Step 1 Set the toggle switch to the OFF position and remove all ice from the bin.

Step 2 Remove the 2 thumbscrews and white plastic panel.

Step 3 Disconnect water supply line at float valve quick disconnect by depressing stainless steel lever (refer to disassembly for cleaning for procedure).

Step 4 Follow the chart and premix cleaner and water.

	Amount of Water	Amount of Cleaner
		Part Number 000000084
	1 gallon (3.8 Liters)	3 ounces (90 ml)

Step 5 To start cleaning, move the toggle switch to the ICE position.

Step 6 Wait about 45 seconds until the dump valve light de-energizes. Fill the evaporator and reservoir with cleaning solution. The ice machine will make ice with the cleaning solution and deposit the ice in the bin. Add the remaining cleaner/water solution when the water level in the reservoir drops.

NOTE: Do not allow the water level to drop below the water level probes. The ice machine will discontinue the cycle when the water level probes open (lose water contact) for more than 30 seconds.

Step 7 After all of the cleaner/water solution has been added reconnect the water supply line to the float valve. Continue the freeze cycle for 10 minutes to remove the cleaning solution from the water circuit.

Step 8 Place the toggle switch in the OFF position.

Step 9 Disassemble the ice machine and hand clean all parts (refer to disassembly for cleaning/sanitizing).

Step 10 Hand sanitize all parts (refer to disassembly for cleaning/sanitizing for procedure).

Step 11 Remove and discard all ice produced during the cleaning process.

Step 12 Reassemble ice machine.

Step 13 Disconnect water supply line at float valve quick disconnect by depressing stainless steel lever.

Step 14 Remove the top cover from water reservoir.

Step 15 Remove the water level probes from the top cover and with the wires attached, place the water level probes (stand upright) inside the water reservoir.

Step 16 Refer to chart and premix water and sanitizer.

Amount of Water	Amount of Sanitizer
6 Gallons (23L) Cool Water	4 ounces (120 ml)

Step 17 To start sanitizing, move the toggle switch to the ICE position.

Step 18 Wait about 45 seconds until the dump valve light de-energizes. Fill the evaporator and reservoir with sanitizer/water solution. The ice machine will make ice with the sanitizer/water solution and deposit the ice in the bin. Add the remaining sanitizer/water solution when the water level in the reservoir drops.

NOTE: Do not allow the water level to drop below the water level probes. The ice machine will discontinue the cycle when the water level probes open (lose water contact) for more than 30 seconds.

Step 19 After all of the sanitizer/water solution has been added to the reservoir, reconnect the water supply line at the float valve quick disconnect.

Continue the sanitize cycle for 10 minutes to remove the sanitizing solution from the water circuit.

Step 20 Place the toggle switch in the OFF position, then disassemble the ice machine and hand sanitize all parts (refer to disassembly for cleaning/sanitizing for procedure).

Step 21 Remove and discard all ice produced in the sanitizing process, then reassemble the ice machine and reconnect the water supply.

PROCEDURE TO CLEAN HEAVILY SCALED FLAKE ICE MACHINES

Step 1 Set the toggle switch to the OFF position and remove all ice from the bin.

Step 2 Remove the 2 thumbscrews and white plastic panel from the interior back wall of the bin.

Step 3 Disconnect water supply line at float valve quick disconnect by depressing stainless steel lever.

Step 4 Refer to chart below:

Premix cleaner with lukewarm water in a nonmetallic container.

	Water	Mix Cleaner and Water
		Use Ice machine cleaner part
Model	Reservoir	number 000000084 only
	Capacity
		Cleaner	Water
QF0406A	48 oz (1.4 L)	32 oz (0.94 L)	16 oz (0.5 L)

Step 5 Remove all water from the evaporator and water reservoir. Start an ice making cycle by moving the toggle switch to the ICE position. Water will flow through the water dump valve and down the drain for 45 seconds. After 45 seconds move the toggle switch to the OFF position. Lift the top cover of the water reservoir and add the entire cleaner/water solution.

Leave the cleaner/water solution in the evaporator for a minimum of 4 hours.

Step 6 Move the toggle switch from OFF to ICE. The cleaner/water solution will flow through the water dump valve and down the drain for 45 seconds.

Step 7 Move the toggle switch to the OFF position, then follow the standard cleaning and sanitizing procedures for the model ice machine you are cleaning.
