FOR THE INSTALLER

Location:

Install the machine be installed in a location where it has enough space around it to be accessible for service. A minimum of 6" must be allowed at the back and sides for air circulation on air cooled models. Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the environmental limitations.

Storage Bin:

Tip the storage bin on its back, using parts of the carton to protect the exterior finish. Install the legs into the threaded holes in the bottom of the bin. Turn the leg levelers all the way in preparation for leveling later. Return the bin to the upright position, remove paper covering the bin gasket. Note: Do not push bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the legs and the leg mounts. Install the appropriate bin top on the bin, according to the instructions for the bin top.

Ice Machine:

The machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough to install on top of the bin. After the unit is placed on the bin, line it up so it is even with the back side. Secure the machine to the bin with the hardware provided with the machine.

Remove the front panel and remove any shipping blocks.

Note: When placing 2 of these machines on a BH801 without the bin top, removal of the 2 service panels facing each other will make future service easier:

1.Remove the 2 top panel screws that will face each other.

2.Remove the 2 service panels that will face each other.

3.Add a strip of gasket, such as Scotsman part number 19-0503-04, to the 2 base edges that will face each other and around service panel space on the 2 panels that will face each other.

When the 2 machines are placed on the bin, the gaskets will seal the bin top area and the space between the machines.

Water Limitations:

An ice machine is a food manufacturing plant: it takes a raw material, water, and transforms it into a food product, ice. The purity of the water is very important in obtaining pure ice and in maximizing product life. This section is not intended as a complete resource for water related questions, but it does offer these general recommendations:

1.Check with a water treatment specialist for a water test, and recommendations regarding filters and treatment.

2.In most cases, the water used to make ice should be filtered or treated, depending upon the water. There is no one type of water filter that is effective in all situations. That is why a water test is important.

RO Water Limitation: Water conductivity must be no less than 35 microSiemens/cm.
