Prior consideration for the location shall include:

• Indoors, with a minimum room

temperature of 50 room temperature of 100

F. and a maximum

• Water temperature to the machine

should be between 40

Location:

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 with

any type of door or curtain. If the unit is built in, it will pull air in from the right side of the front panel, and exhaust it out the left side of the front panel. If the left side of the machine is left open, warm air will be discharged from the

left side panel.

WATER FILTER

(FIELD SUPPLIED)

ELECTRICAL, WATER, AND DRAIN

FOR THE PLUMBER Water supply and drain connections.

1. The recommended water supply line is a 1/4" o.d. copper tube, the water pressure must have a minimum incoming pressure of 20 psig.

2. Connect the tubing to the 3/4" hose coupling thread water inlet fitting at the back of the icemaker. An optional adaptor to go from the 3/4" hose coupling thread to 1/4" compression fitting is available from

your dealer under part number 0533238.

Or a similar adaptor can be purchased from a hardware store.

POWER CORD

3. Install a shut off valve in 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 1/4" fall per foot of horizontal run is recommended. Install the drains per the local codes. 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 equipped with a grounded plug connection. Under no circumstances must the ground post be altered or removed. Extension cords are not permitted.

ADAPTOR

(FIELD SUPPLIED)

Be certain that the icemaker is connected to its own electrical circuit and is individually fused. The maximum allowable voltage variation should not exceed ten percent of the nameplate rating.

All external wiring should conform to the National, State, and local electrical code requirements. Usually an electrical

1. Is the Cabinet level?

2. Have all the electrical and piping connections 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 the cabinet exterior been wiped clean?

FINAL CHECK

7. Are all internal parts in place, including the spray platform and curtain?

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

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

CS55 INITIAL START UP

1. Open water supply valve.

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

3. Remove front panel.

4. Check the cube size control shaft, it should be in a preset cube size position. If not, turn it 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 thru a "dry" cycle, this will take about 10 minutes. Then the water fill and harvest cycle will begin.

6. Observe the water fill cycle:

• The water inlet valve opens.

• Incoming water flows from the 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.

• Extra water flows thru the purge valve

for 15 seconds and then the fan and pump will stop.

• Water continues to enter the machine

and overflows a standpipe in the reservoir and down the drain.

This will take about 2 the freeze cycle will begin.

7. Check the operation of the freezing cycle:

⁄2 minutes. After that

• Compressor is running.

• Water pump is spraying water through

the spray nozzels.

• Icemaking begins, the water gets very

cold, and 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.

December, 1987

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 the 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 1/4" 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. See page 11. 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 ice cubes are cloudy only on the bottom or in the center, the machine may be running out of water before the end of the freezing cycle.

10. Test the bin full shut off. To test this, hold some ice on the bin thermostat bracket (the stainless steel tube on the left 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 Scotsman.

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