SCCG30 & SCCP30 Service Manual Air flow 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. On/Off Switch Ice Making Area Warm Air Out Air Intake 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.
SCCG30 & SCCP30 Service 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.
SCCG30 & SCCP30 Service Manual Door Covering Door Panel Custom Panel The ice machine is supplied without a conventional door covering so it can be decorated to the user’s preference. Scotsman offers several coverings including white, black and stainless steel. In addition, a custom built panel can be placed onto the door. A custom panel of wood or other material not exceeding 15 lb can be attached to the door. Attachment is from the ice side of the door. Holes are provided in the door for this purpose.

SCCG30 & SCCP30 Service Manual Installation: Water & Drain The recommended water supply tubing is ¼ inch OD copper. Stainless steel flex or reinforced PVC tube may also be used. Install an easily accessible shut-off valve between the supply and the unit. This shut-off valve should not be installed behind the unit. Drains There are two types of ice machine models, one that drains by gravity and one that has an internal drain pump.
SCCG30 & SCCP30 Service 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. 1. Place the ice machine in front of the installation opening. Adjust leveling legs to the approximate height. 2. Remove the front service access panel and the upper back panel.
SCCG30 & SCCP30 Service Manual Electrical & Start Up 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.

SCCG30 & SCCP30 Service Manual Cube Size Adjustment The size of the ice cubes is determined by how long the ice machine is in the freezing cycle. That is controlled by the cube size thermostat. Side Views of Cubes The cube size thermostat's sensing portion is attached to the suction tube, near the outlet of the evaporator. As the machine makes ice, the temperature of the suction tubing falls. When it reaches a preset point, the thermostat's contacts close and connect power to the electronic timer.
SCCG30 & SCCP30 Service Manual Harvest Time Adjustment The harvest time can be adjusted so that all the ice is released during the harvest period, with a few seconds extra for a safety margin. The adjustment range is between 2 to 5 minutes. There is an adjustment screw on the surface of the electronic timer. Rotate the screw CCW to reduce harvest time, and CW to increase it. It should be set to match the machine's performance.
SCCG30 & SCCP30 Service 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. The machine can be shut off anytime by moving the On/Off switch to OFF.. The machine will shut off immediately. What shouldn’t be done? Never keep anything in the ice storage bin that is not ice.
SCCG30 & SCCP30 Service Manual How to clean the condenser and winterize.

SCCG30 & SCCP30 Service Manual Refrigeration Service This ice machine use R-134a type refrigerant. There are specific rules for handling that refrigerant. To check for system pressures, add a field supplied clamp-on type service valve as a temporary means of system access. After diagnosis and before final repair, replace the clamp-on type valve with valves that are brazed onto the process tubes of the system. Use a low flow of dry nitrogen when brazing on the system.
