ICE Series Electrical System

Timed Freeze

When the freeze timer is energized, the machine is in the timed portion of the freeze cycle. The freeze timer will time out the remainder of the freeze cycle. Once the time has passed, the machine will enter the harvest cycle.

Freeze Timer

The freeze time is an adjustable timer used to control the ice bridge thickness. The freeze timer is factory set but may need to be adjusted upon initial start up of the machine. When time is added to the freeze timer, the length of the freeze cycle is increased, therefore the ice bridge thickness is increased. When time is removed from the timer, the freeze cycle is decreased and the ice bridge thickness is decreased.

The freeze timer can be adjusted by sliding one or more switches to either the ON or OFF position to obtain the setting which will produce

the proper bridge thickness. A timer setting of 128 and 256 switched ON will provide an initial timer setting.

The ice bridge thickness should be approximately 3/16” (5mm) on the ICEU undercounter series, ICE0250 and ICE0305, and 1/8” (3 mm) on ICE0400 and larger units. If the bridge is too thick, remove enough time from the timer to achieve proper thickness. If the bridge is too thin, add enough time to the timer to achieve proper thickness.

Bridge Thickness

Check the freeze timer for proper operation as follows: Make sure that the high temperature safety control is not open, see page F8. Turn the machine OFF and disconnect the incoming power by unplugging the machine or switching the circuit breaker OFF. Attach one lead of a voltmeter to terminal 1 and the other lead to terminal 3 of the timer.

Reconnect incoming power and turn the machine to the ICE position. The volt meter should read zero volts until the timer initiate closes at which point the timer will energize and line voltage should be read.

When the timer counts out, the voltmeter will again read zero volts. The time it takes the freeze timer to time out, once it has been energized should match the timer adjustment. If it does not or if the timer never closes, the timer is defective.

Note: The hot gas delay timer utilized on the ICE1400, ICE1506, ICE1606, ICE1800 and ICE2100 Series cubers should always be set at 4 seconds. (Not applicable on Version 3)
