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.
Ice made by this machine will have a lower mineral content than the water it was made from. This is due to the method of making ice. Purer water will freeze first in the ice making molds. The reason for this is that anything dissolved in water lowers the water’s freezing temperature. This concentrates most of the impurities in the ice machine water reservoir where they may form hard deposits known as scale. The machine dilutes the concentration of minerals by over-filling the reservoir during the harvest cycle (with the excess water flowing down the drain). s. Between 2 and 4 pints of water flow into the unit each cycle. Between 1 and 3.5 pints of that rinses the reservoir and goes down the drain.
Some impurities will inevitably remain, and will stick to the parts in the machine, and will cause malformed ice cubes. Eventually, built up mineral scale can shorten machine life.
To keep the machine operating properly, these impurities or minerals will have to be regularly dissolved by an acid cleaning, using Scotsman Ice Machine Scale Remover. Directions for this may be found in the section under cleaning.
Filters and Treatment
In general, it is always a good idea to filter the water. A water filter, if it is of the proper type, can remove taste and odors as well as particles. Some methods of water treatment for dissolved solids include reverse osmosis, and polyphosphate feeders.
RO Water
This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm. A reverse osmosis system should include post treatment to satisfy the R.O. water’s potential aggressiveness. Deionized water is not recommended.
Because water softeners exchange one mineral for another, softened water may not improve water conditions when used with ice machines. Where water is very hard, softened water could result in white, mushy cubes that stick together.
If in doubt about the water, contact a local point of use water specialist for recommendations on water treatment.
Installation Overview
The ice machine must:
•be connected to cold, potable water
•be connected to a drain
•be connected to the proper power supply
•be able circulate air through the vents at the front.
Note: Do not build in so that the door is recessed.

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.
Door Panel Attachment
To attach a Scotsman supplied panel:
Note: If door swing is to be changed, it must be done before panel is attached.
The panel will be held on by 6 sheet metal screws and 2 machine screws.
1.Remove the gasket and retain for later use.
2.If the door panel is stainless steel, remove any plastic covering the stainless steel panel.
3.Place the panel onto the outside of the door, and secure it to the door using two machine screws, located at the left center and right center.
4.Fasten the panel to the door using the 6 sheet metal screws. In the hinge area, use the outermost screw holes.
5.Place the covers over the hinge areas, and secure each cover to the door using a sheet metal screw.
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.
See instructions in information packet to create and attach a custom panel:
6.Insert hole plug over screw installed in step 5.
7.Return the gasket to its original position.

Custom Panel
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.
To create and attach a custom panel:
•Panel width: 14 7/8”
•Panel height: Between 29 3/8” and 30 3/8”.
•Panel thickness: 5/8” to ¾”
10. Mount panel to door using wood screws or supplied panel mounting screws.
Note: When installed Ice machine must be adjusted for height to position top of door to desired clearance.
1.Measure overall height of cabinet opening where ice machine will be (floor to bottom of countertop edge).
2.Determine desired kickplate space (from bottom of door to floor). This could be equal to the adjacent cabinet’s kickplate space or another space the user wants.
3.Subtract kickplate space from cabinet opening.
4.Subtract 1/8 or more for clearance space between top of door and bottom of countertop edge from cabinet opening. This is the maximum door length.
5.Cut panel to width.
6.Cut panel to length (cabinet space - kickplate space - top clearance = length).
7.Determine top of panel.
8.Mark hole locations using drawing on the back of these instructions. Drawing assumes top of panel will be flush with top of door. Measure hole locations from the top of the panel.
9.Drill pilot holes for wood screws. Use drill stop to prevent drilling through the panel.
