Installation Instructions Section 2 GENERAL GUIDELINES FOR ROUTING LINE SETS Condensers must be mounted horizontally with the fan motor on top with nothing obstructing it. There must be at least a 16" (41 cm) clearance from the bottom for air intake. The front coupling panel and one other panel (back or side) must also be unobstructed. First, cut a 2.5" (6.35 cm) circular hole in the wall or roof for tubing routing. The line set end with the 90° bend will connect to the ice machine.
Section 2 Installation Instructions CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES Make the following calculations to make sure the line set layout is within specifications. Line Set Length 1. Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise. (Example: A condenser located 10 feet above the ice machine has a calculated rise of 17 feet.) The maximum length is 100' (30.5 m). The ice machine compressor must have the proper oil return.
Installation Instructions Section 2 LENGTHENING OR REDUCING LINE SET LENGTHS REMOTE RECEIVER SERVICE VALVE In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser. The receiver service valve is closed during shipment. Open the valve prior to starting the ice machine.
Section 2 Installation Instructions Remote Ice Machine Usage with Non-Manitowoc Multi-Circuit Condensers WARRANTY FAN MOTOR The sixty (60) month compressor warranty, including thirty six (36) month labor replacement warranty, shall not apply when the remote ice machine is not installed within the remote specifications. The foregoing warranty shall not apply to any ice machine installed and/or maintained inconsistent with the technical instructions provided by Manitowoc Ice, Inc.

Section 3 Operation Ice Making Sequence Of Operation NOTE: The toggle switch must be in the ice position and the water curtain/ice dampers must be in place on the evaporator before the ice machine will start. Water Purge Cycle The ice machine purges any remaining water from the water trough down the drain. SAFETY LIMITS Safety limits are stored and indicated by the control board after three cycles. The number of cycles required to stop the ice machine varies for each safety limit.
Section 3 Operation 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 mm). Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do not require any adjustment.
Section 4 Maintenance Descaling and Sanitizing CLEANING/SANITIZING PROCEDURE GENERAL This procedure must be performed a minimum of once every six months. You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty. Descale and sanitize the ice machine every six months for efficient operation.
Section 4 Maintenance Remedial Cleaning Procedure Step 3 Remove all ice from the bin/dispenser. ! Caution Use only Manitowoc approved Ice Machine Cleaner/ Descaler and Sanitizer for this application (Manitowoc Cleaner/Descaler part number 94-05463 and Manitowoc Sanitizer part number 94-0565-3). It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling. Read and understand all labels printed on bottles before use.
Maintenance Section 4 Step 7 Mix a solution of cleaner/descaler 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 descaler/water mixture to descale all components.
Section 4 Maintenance Detailed Descaling and Sanitizing Procedure Ice machines that are heavily scaled or have not been cleaned on a regular basis will need to run this procedure. 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.
Maintenance Section 4 Step 7 Mix a solution of descaler 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 Descaler Water 1 gal. (4 L) Mixed With 16 oz (500 ml) cleaner/descaler Step 8 Use 1/2 of the descaler/water mixture to descale all components.
Section 4 Maintenance Step 17 Refer to step 6 and disassemble components. After dissembling proceed to step 18. Step 18 Mix a solution of sanitizer and warm water. Solution Type Sanitizer Water 6 gal. (23 L) Mixed With 4 oz (120 ml) sanitizer Step 19 Use 1/2 of the sanitizer/water solution to sanitize all removed components. Use a cloth or sponge to liberally apply the solution to all surfaces of the removed parts or soak the removed parts in the sanitizer/water solution.
