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
Combine time in seconds
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)
