Installation

ICEU060

Location:

Prior consideration for the location of the ice machine shall include:

Installation location to be indoors with a minimum room temperature of 50 F and with a maximum room temperature of 100 F.

The incoming water temperature to the machine should be between 40 F and 100 F.

Service Access. Allow enough space at the rear of the cabinet for the utility connections. Allow enough space for the machine to be pulled out from its installed location. Do not build a floor in front of the machine that would prevent its removal.

Air Circulation. The front panel must remain unobstructed. Do not block the front panel area with any type of door or curtain. The air intake is on the right hand side of the front panel, and the exhaust is on the left side of the front panel and the cabinet left hand side panel. If the unit in installed in a “built-in” cabinet, position the machine so that the left side of the unit is tight against the cabinet.

Installation

ICEU060

Water Supply and Drain Connection:

1.The recommend water supply line is ¼ inch O.D. copper tubing. The minimum incoming water pressure should be 20 psig.

2.Connect the water supply tubing to the water inlet fitting (3/4 hose thread) at the rear of the icemaker. An optional adapter (1/4 compression x ¾ hose thread) is available under part number 1011337-43, or from a local hardware store

3.Install a water shutoff valve on the incoming water line near the icemaker so that the water can be shut off for service.

4.Connect a gravity drain line to the drain connection at the icemaker. A minimum slope of ¼ inch fall per foot of horizontal run is recommended. Install the drains per local code. A vent is recommended on the highest point of the drain tube, and the drain tubing must be rigid pipe.

DO NOT use flexible tubing.

Electrical

1.Locate the nameplate on the lower rear panel and check that the location source voltage and capacity are correct for this unit. The unit is supplied with a grounded plug connection.

2.Under no circumstances must the ground post be altered or removed.

3.Be certain that the icemaker is connected to its own electrical circuit and is individually fused.

4.The maximum allowable voltage variation should not exceed ten percent of the name plate rating.

5.All external wiring should conform to the National, State, and local electrical code requirements. Usually an electrical permit and the services of a licensed electrician will be required to install the receptacle.

Final Check:

1.Is the cabinet level?

2.Have all the electrical and piping connection been made?

3.Has the voltage been tested and checked against the nameplate rating?

4.Is the unit plugged into a separate electrical circuit?

5.Is the water supply line shut off valve installed and is the water turned on?

6.Have the bin interior and cabinet exterior been wiped clean?

7.Are all internal components in place including spray platform and curtain?

8.Have the internal refrigerant lines been checked for rubbing and chaffing?

9.Has the machine been installed indoors, in a controlled environment with adequate air circulation around the machine, and where it can be serviced?

Initial Start Up

ICEU060

1.Open the water supply valve.

2.Move electrical breaker or switch to the ON position.

3.Remove the front panel.

4.Check the cube size control shaft, it should be in a preset position. If not, rotate the control shaft clockwise until the unit comes on.

Note: Cube size adjustments may be required. Start with the shaft in the “mid” position.

5.The machine will go through a “dry cycle”; this will take about 10 minutes. The water fill and harvest cycle will begin.

6.Observe the water fill cycle:

The water inlet valve opens.

Incoming water flows from the water valve through the tubing to the top of the icemaker.

Water flows around the inverted ice cube cups and drains through holes into the reservoir.

The reservoir begins to fill up with water.

Water continues to enter the machine and overflows a standpipe in the reservoir and down the drain. This will take about 3 ½ minutes. After that, the freeze cycle will begin.

7.Check the operation of the freezing cycle:

Compressor is running.

Water pump is spraying water through the spray nozzles.

Ice making begins, ice begins to form in the cube molds.

8.Check that the plastic curtain assembly hangs down evenly in the opening and that no large streams of water are passing through.

Note: Some water will drip from the reservoir as the machine runs, this is normal.

9.After about 20 minutes, the machine will begin to release ice. This is called the harvest cycle.

Observe the first cube harvest:

Check the size of the ice cubes.

Note: The normal size of the ice cube has a ¼ inch depression in the wide end.

If the cubes are not filled out, adjust the machine to make larger ice cubes by turning the cube size control shaft clockwise.

If the cubes are overfilled, adjust the machine to make smaller ice cubes by turning the cube size control counter-clockwise.

In both cases, the next cycle of cubes harvested must be observed, and further corrections may be needed.

If the ice cubes are cloudy, an extreme water condition may exist. Confirm that they are cloudy by placing them in a glass of cold water. If, in the water, they remain cloudy, you may want to have the water tested by a water treatment specialist. If the cubes are cloudy only on the bottom or in the center of the cube, the machine may be running out of water before the end of the freeze cycle.

10.Test the bin full shut off. To test this, hold some ice on the bin thermostat bracket (the stainless steel tube in the left-hand side of the ice storage bin). The icemaker should stop within a few minutes of having ice on that tube.

11.Fill out the Warranty Registration and Customer Evaluation form, and mail both to Ice-O-Matic.

12.Make sure the user understands the operation and maintenance requirements for the icemaker. Leave the service manual and name of the local Ice-O-Matic service agency with the user.

How It Works

ICEU060

Component Description

Cube Size Control

The Cube size control is located in the front of the control box, behind the front panel. The sensing capillary tube of the cube size control is routed out of the control box into its bulb holder on the evaporator coil. It is a reverse acting temperature control with double throw contacts. Turning its knob all the way counterclockwise also shuts off the icemaker.

Compressor Toggle Switch

The compressor toggle switch is located on the side of the control box. When moved to the ON position, it makes a circuit to the compressor. When moved to the OFF position, the other components will still operate.

Water Pump

The water pump operates during the freezing cycle only, pumping water through the spray nozzles into the inverted spray cups.

Inlet Water Solenoid Valve

The water solenoid valve, located in the back panel of the unit, is energized only during the harvest or cleaning cycles. When energized, it allows a metered amount of water to flow into the machine (.21 GPM). This water flows to the top of the evaporator and then down into the reservoir.

Bin Thermostat Control

The bin thermostat control body is located in front of the control box just beside the cube size control. The thermostat sensing tube is located in the ice storage bin on the left side wall and will automatically shut the icemaker off when the bin is full and restart when ice is removed. Factory settings are 36º F cut out and 39º F cut in. It can be adjusted by turning the adjustment screw visible through the control box cover.

Hot Gas Valve Assembly

The hot gas valve assembly is comprised of two components, the valve body and the coil. These components are located on the discharge line of the compressor and are activated by the cube size control (harvest cycle). When the coil of the hot gas valve is energized, it magnetically lifts the plunger in the hot gas valve body. This allows hot refrigerant gas to by-pass the condenser and go directly to the evaporator.

Spray Platform and Chute

The spray system used on this unit is of the stationary type. The water is forced by the water pump into the platform chamber and sprayed into the inverted cup molds through a set of six spray nozzles.

Fan Motor

The fan motor is electrically connected through the cube size control and runs only during the freeze cycle.

Hermetic Motor Compressor

The compressor is a vapor pump, forcing refrigerant gas throughout the refrigeration system.

How It Works

ICEU060

Water System

Freezing Cycle

The refrigeration process creates cold temperatures within the evaporator coils and removes heat from the water sprayed up into the inverted ice cube cups. When enough heat is removed, the water changes into ice, and forms where it is the coldest: in the ice cube cups.

Minerals contained in the supply water will not freeze and are drained away. Mostly pure water will be frozen into the ice cubes.

During the freezing cycle, the compressor, fan motor, and water pump are operating. Water is continuously freezing or being sprayed and recirculated. When the evaporator temperature is lowered to the cold temperature setting of the cube size control, it ends the freezing cycle and starts the harvest cycle.

Harvest Cycle

The hot gas valve opens and hot refrigerant gas is discharged into the evaporator. The inlet opens and a fresh supply of water flows to the top of the evaporator and then drains into the reservoir.

The ice cubes have been released from the inverted cube cups in the evaporator by the warming effect of the hot refrigerant gas condensing in the evaporator tubing, plus the incoming water flowing around the inverted cups. The released ice cubes drop onto the spray platform and through the curtain assembly into the ice storage bin.

The cube size control thermostat senses the warmer temperatures of the harvest cycle, and at a preset temperature, opens the circuit to the hot gas and inlet water valves. Both valves then close.

The harvest cycle is complete, and the freezing cycle restarts.

The automatic ice making process continues until the bin is full of ice, and the bin thermostat senses a colder temperature.

The bin thermostat then opens the circuit to all components and the automatic ice making process stops.

How It Works

ICEU060

Refrigeration System

Freezing Cycle

The ice cubes are formed in an inverted mold that is refrigerated.

The refrigeration process begins at the compressor. There, refrigerant vapor is compressed and flows from the compressor through the discharge line as a high temperature, high pressure gas. In the discharge line there is a strainer with two outlets; one leads to the condenser, and the other one to the hot gas valve. Because the hot gas solenoid is closed, the gas flows to the condenser, where heat is transferred from the refrigerant to the air passing through the condenser. The refrigerant then condenses into a high pressure liquid.

From the condenser, the liquid refrigerant flows through the liquid line, and the liquid line filter drier. After the filter drier, the liquid refrigerant enters the metering device, a capillary tube. After passing the restriction of the capillary tube, the refrigerant enters an area of relative low pressure, the evaporator. In the tubing of the evaporator, the liquid refrigerant expands and evaporates, absorbing heat from the evaporator tubing and anything in contact with it such as water sprayed against it.

The refrigerant, now a low pressure, low temperature vapor, flows into the accumulator, which traps excess liquid refrigerant. The vapor, now primarily a gas, goes through the suction line and back to the compressor.

Refrigeration System

Harvest Cycle

(When the cubes are released)

The ice cubes have been formed in an inverted mold that was refrigerated. Now the refrigeration system will change to warm the cube mold and release the cubes.

The process begins at the compressor. There, refrigerant vapor is compressed and flows from the compressor through the discharge line as a high temperature, high pressure gas. Before the gas gets to the condenser, it goes through a strainer. The strainer outlet is connected to two tubes, one which leads to a hot gas valve solenoid. When this valve opens, the refrigerant gas follows the path of least resistance and flows through the tubing from the hot gas valve to the evaporator, where the ice cubes are frozen.

At the evaporator, the high temperature gases are cooled by the cold temperatures of the cube mold, and condense onto liquid, transferring heat to the mold which warms up and releases the cubes. The refrigerant, now a low pressure, low temperature vapor, flows into the accumulator, which traps excess liquid refrigerant. The vapor, now primarily a gas, goes through the suction line tube to the compressor where the cycle is repeated.

Adjustment Of The Cube Size

Adjust only when cubes are too large or too small.

(See the illustration at the right)

1.Remove the front panel, locate knob.

2.To increase the cube size, turn knob 1/8 turn clockwise. To decrease the cube size, turn the knob 1/8 turn counter clockwise.

3.Observe the size of the cubes in the next two harvest cycles. If more adjustment is needed, continue adjustments until the correct size is obtained.

Adjustment Of The Bin Thermostat Control

Adjust the bin thermostat when the icemaker turn off too soon (ice level low) or when it turns off too late (ice storage bin overfills.)

To increase the ice level in the storage bin:

1.Rotate the bin thermostat adjustment screw (located under the front panel on the control box cover) clockwise 1/8 turn at a time until the ice level that the machine maintains is correct.

2.Rotate the bin thermostat adjustment screw counterclockwise 1/8 turn at a time until the ice level is correct.

Sanitizing And Cleaning

ICEU060

An Ice-O-Matic ice machine represents a sizable investment of time and money in any company’s business. In order to receive the best return for that investment, it MUST receive periodic maintenance. It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. The following is a list of recommended maintenance that will help keep the machine running with a minimum of problems. Maintenance and cleaning should be scheduled at least every six (6) months.

General

The periods and procedures for maintence are provided as a guide. Cleaning will vary depending upon local water conditions and amount of ice used. Each ice maker must be maintained individually, in accordance with its own requirements.

Icemaker In Place Cleaning

1.Remove the ice from the bin.

2.Remove the front panel.

Ice O Matic Ice0500ha2 Manual

3.Rotate the control knob counterclockwise to the OFF position.

4.Remove the curtain by pulling forward on the left end, and then pulling the curtain to the left and out of the machine.

5.Lift up spray platform, locate the stand pipe to the right of the opening, and pull it out to drain the reservoir. Replace the stand pipe, spray platform, and curtain.

6.Mix approximately 3 ounces of approved ice machine cleaner with 1.5 quarts of warm (95ºF-115ºF) potable water, and pour this solution into the reservoir at the curtain base.

Ice machine cleaner contains acids. These compounds may cause burns. If swallowed DO NOT induce vomiting. Give large amounts of water or milk. Call Physician immediately. In case of external contact, flush with water.

7.Rotate the control knob the “normal” position. Operate the machine for 20 minutes.

8.Then switch the toggle switch to the “cleaning position for about three minutes to release all the cubes from their cups.

9.Switch the cleaning toggle switch to the “operation” position, and allow the machine to run for 30 minutes, or until the next batch of ice is released.

10.Pour hot water into the bin to melt the ice produced during cleaning, and to clean out the drain. Wipe the interior of the bin with mild soap and hot water, rinse with cold water.

To sanitize, prepare ½ ounce of approved (EPA/FDA) sodium hypochloride food equipment sanitizer to 1 gallon of warm water to form a solution with 100 minimum to 200 maximum ppm free chlorine yield, and repeat steps 3-10, except substitute the sanitizer solution for the ice machine cleaner solution.

11.Replace the front panel

Ice Maker Maintenance

1.Shut off water supply to the icemaker.

2.Disconnect the water inlet tube from the connection at the back of the icemaker, and check the screen at that point. If very dirty, carefully pull the screen out and clean it. Reassemble the water line to the icemaker.

3.Open the water shutoff valve.

4.Unplug the power cord to disconnect electrical power to the icemaker.

5.Remove the front panel.

6.Clean the air-cooled condenser fins using a brush or vacuum cleaner, or if needed, coil cleaner. A dirty condenser coil reduces the ice making capacity of this machine.
