Limitations for new remote machines that have the mixing valve mounted in the condenser.

Maximum Rise is 35 feet. Maximum Drop is 15 feet. Maximum equivalent run is 100 feet.

Formula for figuring maximum equivalent run is as follows:

Rise x 1.7 + Drop x 6.6 + horizontal run = equivalent run.

Examples: 35 ft. rise x 1.7 + 40 ft. horizontal = 99.5 equivalent feet line run

35 ft. rise

40 ft. horizontal

Verify the ICE machine is compatible with the remote condenser. Some ice machines and some remote condensers may or may not have a Mixing Valve (Head Master). Only one valve is required per system. Kits are available to modify the condenser for compatibility. For more information contact your Ice-O-Matic Distributor.

General Information

How the ICE Machine Works

A general description of how the ICE Series cubers work is given below. The remainder of the manual provides more detail about the components and systems.

With the ICE/OFF/WASH switch in the ICE position, the compressor, water pump and condenser fan motor (when applicable) will energize starting the freeze cycle.

During the freeze cycle, water is circulated over the evaporator(s) where the ice cubes are formed.

When the suction pressure has pulled down to the proper cut-in pressure of the timer initiate (pressure control), the contacts will close and energize the time delay module (timer). See Page F3 for proper cut-in pressures. At this time the cubes will close to completion.

The remaining portion of the freeze cycle is determined by the timer setting. The timer is pre-set at the factory to achieve the proper ice bridge thickness but may need to be adjusted upon initial start-up, see Page F4 for initial timer settings.

Once the amount of time on the timer has passed, the control relay will be energized and the machine will enter harvest. Power is now supplied to the water purge valve, hot gas valve, and the harvest motor. The water purge valve opens, and allows the water pump to purge the water remaining in the water, removing impurities and sediment. This allows the machine to produce clear ice cubes and keep mineral build up at a minimum. The hot gas solenoid opens allowing hot gas to go directly to the evaporator, heating the evaporator and breaking the bond between the evaporator and the ice slab.

The harvest assist motor, which is also energized during harvest, turns a slip clutch, which pushes a probe against the back of the ice slab. Once the evaporator has reached approximately 40°F (4.5°F) in temperature, the slip clutch overcomes the bonding of the ice to the evaporator and pushes the slab of ice off of the evaporator and into the storage bin. The clutch also actuates a switch that rides on the outer edge of the clutch. When the clutch completes one revolution, the switch is tripped and the machine enters the next freeze cycle.

When ice drops into a full bin during harvest, the splash curtain is held open which activates a bin switch shutting the machine off. When ice is removed from the bin, the splash curtain will close and the machine will come back on.

Cabinet Care

Cleaning stainless steel

Commercial grades of stainless steel are susceptible to rusting. It is important that you properly care for the stainless steel surfaces of your ice machine and bin to avoid the possibility of rust or corrosion. Use the following recommended guidelines for keeping your stainless steel looking like new:

1.Clean the stainless steel thoroughly once a week. Clean frequently to avoid build-up of hard, stubborn stains. Also, hard water stains left to sit can weaken the steel's corrosion resistance and lead to rust. Use a nonabrasive cloth or sponge, working with, not across, the grain.

2.Don't use abrasive tools to clean the steel surface. Do not use steel wool, abrasive sponge pads, wire brushes or scrapers to clean the steel. Such tools can break through the "passivation" layer - the thin layer on the surface of stainless steel that protects it from corrosion.

3.Don't use cleaners that use chlorine or chlorides. Don't use chlorine bleach or products like

Comet to clean the steel. Chlorides break down the passivation layer and can cause rusting.

4.Rinse with clean water. If chlorinated cleansers are used, you must thoroughly rinse the surface with clean water and wipe dry immediately.

5.Use the right cleaning agent. The table below lists the recommended cleaning agents for common stainless steel cleaning problems:

Troubleshooting Trees

How To Use The Troubleshooting Trees

The troubleshooting trees were developed to be used in conjunction with the service information in the sections that follow. If used together as intended, these two parts of the manual will allow the ice machine service technician to quickly diagnose many of the problems encountered with the ice machines. When used as designed, the troubleshooting trees can lead you from a general symptom to the most likely component to suspect as the cause of the problem. The trees are not designed to be “parts changer guides”: please do not use them as such.

Components returned to the factory for warranty are tested by the factory and will not be covered under the warranty policy if they are not defective.

The troubleshooting trees are made of three types of boxes:

CHECK boxes (Rectangle) will suggest a point to check for proper operation, and will often refer you to a page in the service information sections of this manual. The result of the check may lead to another box, or a solution box.

SOLUTION boxes (Hexagon) suggest the most likely component to cause the malfunction described in the heading of the tree. When reaching a solution box, DO NOT immediately assume the component is defective. The final step is to verify that the component is indeed defective, by using the service information in the sections that follow.

To use the troubleshooting trees, first find the page with the heading describing the type of problem occurring. Begin at the top of the page and follow the tree, step-by-step. When a check box is reached, it may be necessary to refer to another section in the manual.

Once a solution box is reached, refer to the appropriate section to verify that the component in the solution box is, indeed, the problem. Adjust, repair or replace the component as necessary.
