2. Features
a) Maximum Water Supply Period – 6 minutes
The harvest water valve will be open during harvest for 6 minutes or the length of 
harvest minus 50 seconds, whichever is shorter. 
b) Harvest Backup Timer and Freeze Timer
The harvest backup timer shuts down the icemaker if, for two cycles in a row, the harvest 
cycle takes more than 0 minutes to complete. The control board will signal this problem 
using  beeps every 3 seconds.
The freeze timer shuts down the icemaker if, for two cycles in a row, the freeze cycle 
takes longer than the time specified to complete. The control board will signal this 
problem using 3 beeps every 3 seconds. The time is factory set using S4 dip switch 9 & 
10.
The alarm reset button on the control board must be pressed with power on to reset 
either of these safeties.
c) High Temperature Safety
The temperature of the suction line in the refrigeration circuit is limited by the high 
temperature safety. This protects the unit from excessively high temperatures. If the 
evaporator temperature rises above 17 ± 7°F (53 ± 4°C), the control board reads a 
.804 kΩ signal from the thermistor and operates the safety. This shuts down the circuit 
and the icemaker automatically stops. 
The control board will signal this problem using 1 beep every 3 seconds. The alarm reset 
button on the control board must be pressed with power on to reset the safety.
d) Low Water Safety
The control board checks the position of the lower float switch at the end of the initial one 
minute water fill cycle and at the end of each harvest cycle. If the lower float switch is 
closed, the control board proceeds to the next cycle. If the lower float switch is open, the 
control board calls for a one minute water fill cycle. After one minute, the control board 
checks the position of the float and either proceeds to the next cycle if the lower float 
switch is closed or calls for an additional one minute fill if the switch is open. This serves 
as a low water safety to protect the water pump.
e) High Voltage and Low Voltage Cut-outs
High voltage and low voltage cut-outs help protect the icemaker from supply voltages 
outside of the accepted range.
If miswiring causes excessive voltage (147Vac ±5% or more for 3 seconds) on 
the control board, the high voltage cut-out shuts down the circuit and the icemaker 
automatically stops. The control board will signal this problem using 7 beeps every 3 
seconds.
The icemaker also automatically stops in cases of insufficient voltage (9Vac ±5% or 
less). The control board will signal this problem using 6 beeps every 3 seconds.
When the proper supply voltage is resumed, the icemaker automatically starts running 
again.
