Flake Ice Machines How To Use This Manual

Page A2

ICE-O-Matic provides this manual as an aid to the service technician for installation, operation, and

maintenance of flaked ice machines. This manual covers all EF and EMF series flaked ice machines.

If used properly, this manual can also help the service technician troubleshoot and diagnose most of

the problems that may occur with the machine.

Sections A and B of this manual provide general and maintenance information. The remainder of the

manual, beginning with Section C, provides troubleshooting information. Section C contains flow

charts called troubleshooting trees. Page C1 provides instructions on using the troubleshooting trees.

Each troubleshooting tree is named to describe a particular problem with the operation of the

machine.

When following the troubleshooting trees, the service technician will be led through questions and

checks and end up at a probable solution. When using the troubleshooting trees it is important that

the service technician understand the operation and adjustments of the components being checked

and the component suspected of being defective. A detailed description of the operation and

adjustments of the components as well as other service information is laid out in the pages that follow

Section C.

Each section, after Section C, focuses on a particular system in the ice machine; water system, drive

system, refrigeration system and electrical system. It is important that these sections be used

together with the troubleshooting trees in Section C.

Most aspects of flake ice machines are covered in this manual. However, should you encounter any

conditions not addressed herein, please contact the ICE-O-Matic Technical Service Department for

assistance at the numbers listed below, or write the ICE-O-Matic Service Department.

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), 110°F (43°C) on 50 Hz. Models.

Note: ICE-O-Matic products are not designed for walk in cooler applications or outdoor

installation.

Incoming Water Supply (See Plumbing Diagram for line sizing Page A7-A9)

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: 60 psi (4.1 bar)

Note: If water pressure exceeds 60 psi (4.1 bar), a water pressure regulator must be

installed.

Drains:

Route bin drain, float 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

around the entire machine.

Stacking

EF and EMF Series ice machines are not designed to be stacked.

Dispenser Application

EF and EMF Series ice machines are not designed to be placed on dispensers.

Electrical Specifications

The machine must be installed on a separate circuit.

Refer to the serial plate at the rear of the ice machine or the charts on Page A5.

Adjustments

Level the machine.

Check the primary and secondary bin control for proper adjustment, Page G3.

Check the safety control for proper adjustment, Page G3.

Check the water in the water float for proper level, Page D1.

Check the water regulating valve adjustment if water cooled, Page F6.
