CU50 Installation and User's Manual Air flow & Control Panel The machine takes in room temperature air at the lower right front and forces warm air out the lower left front. Restricting the airflow will adversely affect the ability of the ice machine to make ice. Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. They meet or exceed the standards of agencies like U.L.
CU50 Installation and User's Manual Water Quality All water, including potable water supplied by municipalities, contains some impurities or minerals. Water absorbs impurities from the air as rain and/or as it flows through the ground. Some of the impurities are solid particles, these are known as suspended solids, and a fine particle filter will remove them. Other impurities are chemically bonded to the water molecules, and cannot be filtered out, these are called dissolved solids.

CU50 Installation and User's Manual Installation: Water & Drain Drains The recommended water supply tubing is ¼ inch OD copper. Install an easily accessible shut-off valve between the supply and the unit. This shut-off There are two types of ice machine models, one valve should not be installed behind the unit. that drains by gravity and one that has an internal drain pump. Note: Do not use self-piercing type valves. Drain Pump Model drain installation 1. Remove the front service panel. 1.
CU50 Installation and User's Manual Gravity Drain Caution: Restrictions in the drain system to the machine will cause water to back up into the ice storage bin and melt the ice. Gravity drain tubing must be vented, have no kinks and slope to the building drain. Air gaps are typically required by local code. outlet of the barbed connector and secure with a clamp. Leave the other end of the tube lying on the floor of the base pan until the unit is positioned over the floor drain. 1.
CU50 Installation and User's Manual Electrical The ice machine is supplied with a power cord. Do not remove the grounding pin from the cord’s plug. Do not use extension cords. Follow all codes.

CU50 Installation and User's Manual Start Up Check list: 1. Has the unit been connected to the proper water supply? 2. Has the water supply been checked for leaks? 3. Has the unit been connected to a drain? After about a half hour, ice will fall into the ice storage bin. The machine makes 24 cubes per batch. It is normal for the first batches of ice to melt, that continues until the bin has cooled. It will take 8 to 10 hours of continuous run time to fill the ice bin.
CU50 Installation and User's Manual Use No special instructions are needed for use. Just take as much ice as you need, the machine will replace it. A scoop is provided, and it can be stored in the machine using the loop of tubing on the right side as a holder.
