EVELING

If legs are used, adjust the leveling legs of the storage bin until the unit is level and all four (4) legs are in sold contact with the floor. Leveling is very important to obtain proper draining and to maintain the proper level in the water pump pan of the ice cuber.

Note: If the bin is to be installed flush to the floor, the bin must be sealed to floor with an approved mastic such as Dow R.T.V. #732, 734, or G.E. #102, 108. This is an N.S.F. requirement and is the responsibility of the installer.

OCATION

1.

Allow at least a minimum of six inches at the rear and side of the ice machine for proper air RHP circulation.

2.

This unit has been designed to be installed in an indoor location which is clean and which can be adequately ventilated. The air and water temperatures should never exceed 100°F or fall below

50°F. (Temperatures above 100°F will cut the ice making capacity below an economical level.

Temperatures below 50°F will cause a malfunction of thermostatic sensors.)

3.

The unit should be located where air circulation is not restricted. The unit should not be located near a kitchen grill. Air which contains grease vapors will deposit grease on the condenser. The condenser should always be kept clean.

2.

Mount the ice maker to the top of the ice storage bin or adapter in the proper position over the ice drop opening. The ice maker must then be sealed both on the outside and the inside bottom edges with an approved N.S.F. mastic such as Dow R.T.V. #732, 734, or G.E. R.T.V. #102, 108. This is an

ONNECTIONS

Water supply – (install per local codes) (see Figure 4).

The water inlet connection to the unit is a 3/8” male flare connection located at the rear of the ice machine.

Warning

- If the water pressure exceeds 50 pounds, a water pressure regulator should be installed in the water inlet line between the water shut-off valve and the strainer.

Install a reducer fitting on the shut-off valve to accommodate the water stainer, which is supplied with each ice machine and MUST be used. This is very important for cleaning. Connect either 3/8” or 1/2” copper tubing between the water inlet fitting of the ice machine and the water strainer.

For water cooled units

Two water inlet connections are provided. One is for the ice making (evaporator) section which is located on the back of the machine and is a 3/8” flared connection. The other is for the water cooled condenser.

Series 322 Ice Cube Machine Installation Instructions

The reason for the separate water inlet connections is that some installations use a water tower for cooling the water used in the water cooled condenser and some installations use treated water (filtered) for the ice making inlet water connections. Be sure to install water line (incoming) to the 3/8” male flare connection on the back of the unit that supplies water to the water regulating valve inside.

RAIN

Provide a suitable trapped open drain as close as possible to the area where the ice maker is going to be installed. This may be an existing floor or a 1-1/4” trapped open drain. Two separate drain lines are required for air cooled units, one for the storage bin and one for the dump valve drain hose.

An additional separate drain line will be required for water cooled units from the outlet of the condenser coil to the drain. Run all gravity drain lines with a good fall to the open drain.

All Plumbing Must Be Installed in Accordance with Local Codes.

NOTE: In some cases it may be necessary to insulate the water supply line and drain line. Condensate dripping to the floor can cause serious staining of carpets or hardwoods.

After the ice cuber has been unpacked and leveled and all plumbing and electrical connections have been made, start the unit, and check for proper operation.

A cuber has three separate circuits: the water circuit, the refrigerant circuit and the electrical circuit.

1.

Start checking the water circuit by making sure that there are not thread of flare joint leaks, either outside the unit or in the compressor section. Next check the water flow over the evaporator and make sure that all holes in the water distributor are open (see Figure 6) and that there is no undue splash or loss of water into the ice bin.

2.

Check to see if the float valve is functioning properly and the correct water level is being maintained.

Adjust if necessary.

3.

Check the refrigerant circuit by making sure that the condenser fan is running. (This will be evident by air noise.) Is the compressor running? (Feel the casing for vibration.) Is the evaporator getting cold?

4.

Check bin-harvest switch operation. (See procedure in manual.)

Turn on the ice machine and move the evaporator curtain(s) away from the evaporator(s). The ice machine should then shut off in approximately 10 seconds. (See Details A and B.)

Slowly let the evaporator curtain(s) move back toward the evaporator(s) until the bottom edge of the curtain(s) is at least at the bent edge of the water reservoir or closer to the evaporator. With the curtain(s) at that position, the machine should start. (See Detail C.)

If lime scale is present, add 3 oz. of “Calgon Nickel Safe Ice Machine Cleaner” directly into water reservoir. Circulate for not longer than 10 minutes. Depress dump valve switch on side of control box and allow cleaner or sanitizer to drain away. Allow float valve to fill reservoir with clean, fresh water. Circulate for approximately 1 minute. Depress dump valve switch and allow water to drain away. Repeat three times.

CAUTION

- All ice machine cleaner musts be flushed out of the system before the sanitizing solution is used in Step 5. The reaction of the two chemicals can cause hazardous gasses to be generated.

5.

Pour 1/4 oz. of household bleach into the water reservoir and circulate for 10 minutes to sanitize the circulating water system, including the evaporator, pump, distributor and all interconnecting vinyl tubing. Depress dump valve switch on side of control box and allow cleaner or sanitizer to drain away. Allow float valve to fill reservoir with clean, fresh water. Circulate for approximately 1 minute.

Depress dump valve switch and allow water to drain away. Repeat three times.

6.

Mix sanitizing solution of 1/2 oz. household bleach to one gallon of water. This mixture will provide

200 ppm chlorine. Using a non-metallic bristle brush, scrub the following:

A. Inside surface of the ice bin including top and door.

B. Inside surface of the ice maker to include evaporator section in the ice machine including the top, front panel and evaporator splash curtain.

C. Make sure splash curtain is correctly positioned.

7.

Depress dump valve switch and allow cleaner to drain away. Allow float valve to fill reservoir with clean, fresh water. Circulate for approximately 1 minute. Depress dump valve switch and allow water to drain away. Repeat three times.

REATMENT

Depending on the water source for the ice maker, water treatment may be necessary to prevent calcium or lime scale deposits, bad taste and odor, chlorine problems, as well as slime growth. If these conditions exist, contact your Cornelius Distributor or Dealer for information on water treatment systems Cornelius offers.

TORAGE

If the unit is to be stored in an area where the temperature will drop below freezing, it is most important that all water lines be drained to prevent them from freezing and possible rupture.

To blow out the waterline, disconnect the water supply at the cabinet inlet and use air pressure to force the water into the water reservoir pan. This can then be removed from the water pan.

In order to produce at full capacity, the refrigeration condenser must be kept clean. The frequency of cleaning will be determined by surrounding conditions. A good maintenance plan calls for an inspection at least every two months.

CAUTION

- Condenser cooling fins are sharp. Use care when cleaning.

Clean the air condenser coil from the back of the machine with a vacuum cleaner. Remove all the accumulated dust, lint, and dirt.
