Page 4: Plumbing
If a floor is to be installed after the ice machine, shims the thickness of the floor should be installed under the DC33 to keep the machine level with the floor. Also, allow 1/8" clearance on each side of the cabinet. - Page 5 System, Use Began just before connecting to the fitting. June 1994 6. Route a drain line from the ice machine to the drain/waste receptacle. Note: if using a long horizontal run (more than 5’) the drain should be vented at back of cabinet.

TO INSTALL: Add On Kits Drain Pump Kit The DC33 is delivered either with or without a drain pump. Models without a drain pump drain their water by gravity. However, gravity drain models may be converted to Pump models thru the installation of a Drain Pump Kit and Drain Pump. -
Page 10: Door Kit
Scotsman has a stainless steel panel available to fit this machine, the kit number is SS33. If the material is less than 1/4" thick, the space between the new panel and the original may be filled with cardboard. -
Page 11: Reverse Door Swing
The hinged side of the door may be reversed to the other side if desired: The DC33 was shipped with the door hinged at the left. The door and hinges are designed for placing the hinges on either the right or the left side of the cabinet. -
Page 12: Initial Start Up
What to expect from the DC33 The DC33 will release a batch of 8 ice cubes about every 30 minutes. At the same time the cubes fall into the storage bin, water will be entering the ice machine and draining out. -
Page 13: Operation
The heat is transferred to the air, and the warmed up air is discharged from the ice machine. At the same time ice is forming on the refrigerated surface (located at the upper back of the machine). When the refrigerated surface gets cold enough, the ice machine’s timer will begin to turn. -
