SAFETY INSTRUCTIONS
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
Safety Overview
• Read and follow ALL SAFETY INSTRUCTIONS in this manual and any warning/caution labels on the unit (decals, labels or
laminated cards).
• Read and understand ALL applicable OSHA (Occupational Safety and Health Administration) safety regulations before
operating this unit.
Recognition
Recognize Safety Alerts
This is the safety alert symbol. When you see it in this manual or on the unit,
be alert to the potential of personal injury or damage to the unit.
DIFFERENT TYPES OF ALERTS
Indicates an immediate hazardous situation which if not avoided WILL result in serious injury, death or equipment
damage.
Indicates a potentially hazardous situation which, if not avoided, COULD result in serious injury, death, or equipment
damage.
Indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury or equipment
damage.
SAFETY TIPS
• Carefully read and follow all safety messages in this manual and safety signs on the unit.
• Keep safety signs in good condition and replace missing or damaged items.
• Learn how to operate the unit and how to use the controls properly.
• Do not let anyone operate the unit without proper training. This appliance is not intended for use by very young children or
infirm persons without supervision. Young children should be supervised to ensure that they do not play with the appliance.
• Keep your unit in proper working condition and do not allow unauthorized modifications to the unit.
QUALIFIED SERVICE PERSONNEL
Only trained and certified electrical, plumbing and refrigeration technicians should service this unit. ALL WIRING
AND PLUMBING MUST CONFORM TO NATIONAL AND LOCAL CODES. FAILURE TO COMPLY COULD
RESULT IN SERIOUS INJURY, DEATH OR EQUIPMENT DAMAGE.

WARNING:
SAFETY PRECAUTIONS
This unit has been specifically designed to provide protection against personal injury. To ensure continued protection
observe the following:
Disconnect power to the unit before servicing following all lock out/tag out procedures established by the user. Verify
all of the power is off to the unit before any work is performed.
Failure to disconnect the power could result in serious injury, death or equipment damage.
Always be sure to keep area around the unit clean and free of clutter. Failure to keep this area clean may result in
injury or equipment damage.
SHIPPING AND STORAGE
Before shipping, storing, or relocating the unit, the unit must be sanitized and all sanitizing solution must be drained
from the system. A freezing ambient environment will cause residual sanitizing solution or water remaining inside the
unit to freeze resulting in damage to internal components.
MOUNTING IN OR ON A COUNTER
When installing the unit in or on a counter top, the counter must be able to support a weight in excess of 376 lbs. to
insure adequate support for the unit. FAILURE TO COMPLY COULD RESULT IN SERIOUS INJURY, DEATH OR
EQUIPMENT DAMAGE.
NOTE: Many units incorporate the use of additional equipment such as icemakers. When any
addition equipment is used you must check with the equipment manufacturer to determine the
additional weight the counter will need to support to ensure a safe installation.

BIN CONTROL
The type of bin control used on all WCC & WCF Models is an electronic control. The control is supplied with power to
terminals X1 and X2. Terminals X3 and X4 are a normally closed switch which open when the thermostat sensor bulb
senses ice.
The sensing element is located in a 5/16” stainless steel tube which hangs from the dispense tray cover down through
the center of the drop tube.
To test switch, start the icemaker and block the outlet tube. When the ice fills the drop tube about 1/2 full the icemaker
should shut off. When tube is cleared the ice maker should restart within 5 min.
The Bin control is in electrical series with coil on antifreeze relay along with the low water safety. If unit is water cooled,
the condenser high pressure cut out is also in series.
The Control Switch is held in place inside electrical box by 2 screws. The Control bulb is in the drop tube. It can be
removed by pulling the cable located on the top of the dispense tray cover. When replacing the sensor make sure the
bulb is inserted to the bottom of the thermostat well.
GEAR MOTOR
The gearmotor is equipped with a start relay and a manual reset overload.
When current is applied, the relay energizes and completes the circuit to the start winding. The motor reaches a
predetermined speed and the relay drops out, disconnecting the start winding. The run winding remains in the circuit
as long as current is applied.
The purpose of the overload is to automatically shut off the motor in the event of a mechanical bind of the
transmission, an overload condition within the evaporator or an electrical malfunction. It does this by sensing
amperage draw. If the motor stalls the start relay would energize and stay energized. The amperage would surge 5 to
6 times greater than the normal draw. In this event the overload would shut off the transmission in 4 to 8 seconds.
If the motor is subjected to an abnormal load, but does not reach a stall condition, the overload will react, but over a
greater period of time. The reaction time depends upon the amperage to which it is subjected.
The overload, through the safety circuit, also shuts off the compressor.
