MFI Series For the Installer

Installation Guidelines:

For proper operation of the Ice-O-Matic ice machine, the following installation guidelines must be followed. Failure to do so may result in loss of production capacity, premature part failures, and may void all warranties.

Ambient Operating Temperatures:

Minimum Operating Temperature: 50°F (10°C) Maximum Operating Temperature 100°F (38°C)

Note: Ice-O-Matic ice makers and dispensers are not approved for outdoor installation. Incoming Water Supply

Minimum incoming water temperature: 40°F (4.5°C) Maximum incoming water temperature: 100°F (38°C) Minimum incoming water pressure: 20 psi (1.4 bar) Maximum incoming water pressure: 80 psi (5.6 bar)

Note: If water pressure exceeds 80 psi a water pressure regulator must be installed. Drains

All drain lines must be installed per local codes. Flexible tubing is not recommended. Route bin drain, vented float overflow drain and water condenser drain individually to a floor drain. The use of condensate pumps for draining water is not recommended by Ice-O-Matic. Ice-O-Matic assumes no responsibility for improperly installed equipment.

Water Filtration

A water filter system should be installed with the ice machine.

Clearance Requirements

Self-contained air cooled ice machines must have a minimum of 6 inches (15cm) of clearance at the rear and sides of the ice machine for proper air circulation.

Stacking

Ice-O-Matic MFI ice machines are not designed to be stacked.

Dispenser Application

The MFI ice machine is approved for specific dispenser applications, reference page 3.

Electrical Specifications

Refer to the serial plate at the rear of the ice machine to make sure proper voltage and circuit breaker size have been supplied. Make sure the machine is on a dedicated circuit. The MFI Series are not supplied with an electrical power cord and will need to be installed and wired per local electrical codes.

Adjustments

Level the machine within 1/8 inch in all directions. Adjust the cabinet or bin legs as required. Check the bin control for proper operation. Check the water level in the reservoir for proper adjustment. Check the water regulating valve adjustment if water cooled.

MFI Series For the Installer

Location:

Ice-O-Matic ice machines are designed to be installed indoors in a controlled environment. Install the ice machine in a location where it has enough space around it to be accessible for service. A minimum of 6 inches must be allowed at the back for air circulation on air cooled models. Try to avoid hot, dirty and crowded locations. Be sure that the location of the machine is within the environmental limitations.

Storage Bin:

Remove the bin packaging. Tip the storage bin on its back, using parts of the packaging to protect the exterior finish. Remove the skid and 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. Note: Do not push the bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the bin legs and mounts. Install the appropriate bin top according to the instructions provided with the bin top.

Ice machine:

The ice 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 ice machine to the bin with the hardware provided with the ice machine. Remove the front panel and remove any shipping blocks or packaging material.

Proper functioning of the bin door requires the bin door, when it is opened, to be in a stable position. If the ice machine is too far forward on the bin, the opened door may not be stable, resulting in an unexpected closing of the bin door.

If the ice machine is to be mounted on a bin or dispenser other than an Ice-O-Matic, refer to the manufacturer’s instructions for machine mounting. Ice-O-Matic will not be responsible for damage or injury that results from unexpected closing of the bin door as a result of the ice machine being too far forward on the bin.

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 maximizing product life. This section is not intended as a complete resource for water related questions, but it does offer these general recommendations:

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

●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 in important.

RO Water Limitations:

Water conductivity must be no less that 35 microSiemens/cm.

Notice:

Ice-O-Matic ice machines are designed and manufactured with the highest regard for safety and performance and meet or exceed the standards of UL, NSF and CUL.

Ice-O-Matic assumes no liability or responsibility of any kind for products manufactured by Ice-O-Matic that have been altered in any way, including the use of any part and/or other components not specifically approved by Ice-O-Matic.

Ice-O-Matic reserves the right to make design changes and/or improvements at anytime. Specifications and design are subject to change without notice.

llow 6 “Clearance for Air Circulation

A proper installation locates the ice machine indoors, but in a place where the heat and noise it produces are not objectionable.

Air cooled machines discharge hot air out the back have a minimum of 6 inches of clearance behind the ice machine.

Space for maintenance access is also important. If two units are placed side by side on a bin, side access becomes even more important.

Water Inlet:

●Air Cooled Models: The recommended water supply is clean, cold water. Use 3/8 inch O.D. copper tubing, connect to the 3/8 inch male flare at the back of the cabinet. Install a hand valve near the machine to control the water supply.

●Water Cooled Models: A separate 3/8 inch O.D. copper line is recommended, with a separate hand valve to control it. Connect to the 3/8 inch FPT condenser inlet at the back of the cabinet. The water pressure to all lines must always be above 20 psig, and below 80 psig.

●Water Treatment: In most areas, a water filter of some type will be useful. In areas where the water is highly concentrated with minerals, the water should be tested by a water treatment specialist, and the recommendations of the specialist regarding filtration and/or treatment should be followed.

Drains:

●Air Cooled Models: Connect a rigid drain tube to the ¾ FPT drain fitting at the back of the cabinet. The

Electrical Connections:

Check the ice machine nameplate (located on the back panel) for the voltage requirements, and minimum circuit ampacity. The ice machine requires a solid chassis to earth ground.

Connect the ice machine to its own electrical circuit so it is individually fused. Voltage variation must remain within the limitations, even under starting conditions.

Note: All external wiring must conform to national, state and local electrical codes. The use of a licensed electrician is required to perform the electrical installation.
