Never coil excess refrigeration tubing. 0 to 20 feet (0 to 6.1 m) Rise: The ice machine head section has one oil trap built in which allows for a maximum condenser rise of 20 feet (6.1 m) without additional traps in the suction line. 21 to 35 feet (6.4 to 10.7 m) Rise: The suction line requires an additional Oil Trap (“S” type) to be installed.
Section 2 Installation Instructions Connect The Line Set To The CVD Condensing Unit Step 4 Connecting the line set. To prevent oxidation of the copper, purge line set and condensing unit with dry nitrogen while brazing. ! Warning The condensing unit ships from the factory pressurized with a 50/50 mixture of nitrogen/helium. Bleed off pressure from both suction and liquid line access ports prior to cutting into refrigeration lines.
Installation Instructions Section 2 Step 5 Pressure Test and Evacuate The Line Set and CVD Condensing Unit Schrader valve core removal tools that allow for removal and installation of the valve cores without removing manifold gauge set hoses are recommended to decrease the evacuation time. Leave the line set shut off valves closed (front seated). Pressure test the line sets and CVD condensing unit with 150 psig of dry nitrogen.
Section 2 Installation Instructions Step 6 Open The Valves Prior To Starting The Ice Machine. The suction line, liquid line and receiver service valves are closed during shipment and installation. Open the valves prior to starting the ice machine. A. Slowly backseat (open-turn counterclockwise) the suction line shut off valve. B.

Ice Machine Operation Section 3 Ice Making Sequence of Operation INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF 1. Water Purge Before the refrigeration system starts, the water pump and water dump solenoid are energized for 45 seconds, to completely purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water.
Section 3 Ice Machine Operation AUTOMATIC SHUT-OFF 7. Automatic Shut-Off Ice Machine Head Section: When the storage bin is full at the end of a harvest sequence, the sheet of cubes fails to clear either one or both water curtains. After one or both water curtains are held open for 7 seconds the ice machine shuts off. CVD Condensing Unit: When the refrigerant pressure is low enough to open the low-pressure switch, the contactor coil is de-energized and the compressor and condenser fan motor stop.
Ice Machine Operation Section 3 Operational Checks ICE THICKNESS CHECK GENERAL After a harvest cycle, inspect the ice cubes in the ice storage bin. The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (3.2 mm). Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, a newly installed ice machine does not require any adjustment.
Section 4 Maintenance Section 4 Maintenance Interior Cleaning and Sanitizing GENERAL Step 3 Remove all ice from the bin. 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. The ice machine must be taken apart for cleaning and sanitizing. Step 4 Place the toggle switch in the CLEAN position.
Maintenance Section 4 B. Remove the water curtain Step 6 Remove parts for cleaning. ! Warning • Gently flex the curtain in the center and remove it from the right side. • Slide the left pin out. Disconnect the electric power to the ice machine at the electric service switch box.. A. Remove the splash shield • Pull forward on left and right nylatch connectors until disengaged from ice machine (connectors remain attached to splash shield).
Section 4 Maintenance E. Remove the water level probe D. Remove the water distribution tube • Remove the clamp from the vinyl water hose on the right side of the distribution tube. 2 3 1. LIFT UP 2. SLIDE BACK 3. SLIDE TO RIGHT • Pull the water level probe straight down to disengage. • Disconnect the wire lead from the water level probe. • Remove the water level probe from the ice machine.
Maintenance Section 4 G. Remove the water trough F. Remove the water pump. • Disconnect the water pump power cord. LOOSEN SCREWS • Remove the quarter turn fasteners (turn counterclockwise) securing the trough in place. • Lift up and forward on the front of the water trough while allowing the rear of the water trough to drop. • Remove the water trough from the ice machine. POWER CORD PUMP OUTLET WATER PUMP SV1456B • Disconnect the hose from the pump outlet.
Section 4 Maintenance Step 7 Mix a solution of cleaner and warm water. Depending upon the amount of mineral buildup, a larger quantity of solution may be required. Use the ratio in the table below to mix enough solution to thoroughly clean all parts. Solution Type Cleaner Water 1 gal. (4 l) Mixed With 16 oz (500 ml) cleaner Step 8 Use 1/2 of the cleaner/water mixture to clean all components.
Maintenance Section 4 Step 16 The ice machine will stop after the sanitize cycle (approximately 30 minutes). Place the toggle switch in the OFF position and disconnect power to the ice machine. ! Warning Disconnect the electric power to the ice machine at the electric service switch box.. Step 17 Repeat step 6. Step 18 Mix a solution of sanitizer and warm water. Solution Type Sanitizer Water 6 gal.
Section 4 Maintenance ADDITIONAL COMPONENT REMOVAL The following components may be removed for easier access in some installations or they may need to be removed and cleaned to correct an operational problem. NOTE: At this point, the water dump valve can easily be cleaned. If complete removal is desired, continue with step 4. Water Dump Valve NOTE: During cleaning, do not stretch or damage the spring. The water dump valve normally does not require removal for cleaning.
Maintenance Section 4 Water Inlet Valve Ice Machine Inspection The water inlet valve normally does not require removal for cleaning. Refer to Section 5 for a list of causes for “No Water Entering Water Trough” or “Water Overflows Water Trough. Check all water fittings and lines for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrating against other tubing, panels, etc. 1. When the ice machine is off, the water inlet valve must completely stop water flow into the machine. 2.
Section 4 Maintenance Cleaning the Condenser Removal from Service/Winterization GENERAL GENERAL ! Warning Disconnect electric power to the ice machine head section and the remote condensing unit at the electric service switches before cleaning the condenser. Special precautions must be taken if the ice machine is to be removed from service for an extended period of time or exposed to ambient temperatures of 32°F (0°C) or below.
