Water Service/Drains

Section 1

WATER SUPPLY

Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, remove chlorine, and improve taste and clarity.

Important

If you are installing a water filter system, make sure that you use a separate line for water-cooled condenser.

Filter life will be greatly reduced if filtered water is used for water-cooled condenser.

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.)

• Water pressure to the machine should be between 1.4 to 5.5 bar (20 to 80 psi).

• If water pressure exceeds the maximum 5 bar recommended pressure, obtain a water pressure regulator from your

Manitowoc distributor. Adjust pressure to 2.5 bar (37 psi).

• Install a water shut-off valve.

• Connect to a potable water supply only.

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 3.8 cm (1.5 inch) drop of run for each meter (3 feet), 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

Ice Machine Operation

Ice Making Sequence of Operation

Important

Prior to start up of this machine, a thorough cleaning and sanitization should be performed.

Follow instructions in the maintenance section of this manual.

Initial Start-Up

Priming Water System

The water valve inlet on this machine energizes in the harvest cycle, therefore priming the system with water will allow the system to start up with a full reservoir of water. To prime system, remove water curtain, and add 2 liters of water into the water trough.

1. Freeze Cycle

Turn the on/off/wash switch to on. The compressor, and water pump will start, thus starting the freezing cycle. The pump sprays water into the inverted cups. The water freezes layer by layer, until an ice cube forms in each cup.

At the same time the compressor starts, the condenser fan motor

(air-cooled models) is supplied with power throughout the freeze and harvest cycles. The freeze cycle continues and the evaporator thermostat reaches the adjusted set point.

• EC18/20 (without timer)

A harvest cycle starts.

• EC20 (with timer)/30/40/50/65

The thermostat energizes the timer motor and the cam starts to turn. When the cam cycles through the preset freeze time the relays change position and the harvest is initiated.

• EC65/80

The thermostat energizes the time delay relay. When the timer reaches setpoint (10 minutes factory setting) the harvest cycle is initiated.


2. Harvest Cycle

The compressor continues to operate and the water pump is deenergized. The hot gas valve energizes, allowing hot gas to enter and warm the evaporator.. The water valve is also energized, aiding with harvest, as well as filling up the sump with fresh water for a new freeze cycle.

The ice falls from the cups and is directed into the bin by the ice chute. The harvest cycle continues until:

• EC18/20 (without timer)

The evaporator thermostat changes position.

• EC20 (with timer) /30/40/50/65

The preset harvest time expires.

The hot gas valve, and water valve de-energize. If ice cubes are not contacting the bin thermostat a new freeze cycle is initiated as the water pump energizes and sprays water into the cups,.

3. Automatic Shut-Off

When the storage bin is full, the ice will come in contact with the bin thermostat which is located inside the bin. The machine will stop after approximately one minute of continuous ice contact with the bin thermostat probe.

The ice machine remains off until enough ice has been removed from the storage bin to allow the ice to fall clear of the bin thermostat probe. As the ice clears the probe, the bin thermostat warms up and the machine starts another freeze cycle.

Cleaning the Condenser

Section 4

Water-Cooled Condenser and Water Regulating Valve

WARNING

Disconnect electric power to the ice machine at the electric service switch before performing maintenance on equipment.

A

IR-COOLED CONDENSER

A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life.

The water-cooled condenser and water-regulating valve may require cleaning due to scale build-up.

Low ice production, high water consumption and high operating temperatures and pressures all may be symptoms of restrictions in the condenser water circuit.

Because the cleaning procedures require special pumps and cleaning solutions, qualified maintenance or service personnel must perform them.

Clean the condenser at least every six months.

1. Remove Plastic Front Grill removing two Phillips head screws. Clean Grill openings before replacing.

2. Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins.

3. Shine a flashlight through the condenser to check for dirt between the fins. If dirt remains:

A. Blow compressed air through the condenser fins. Be careful not to bend the fan blades.

B. If dirt or grease remains between fins, consult your service representative.

4. Straighten any bent condenser fins with a fin comb.

WARNING

The condenser fins are sharp. Use care when cleaning them.
