Hoshizaki FD-1001MAH(-C) 사용자 설명서

8

When the inlet water valve opens during fill and refill, a 90-second low water safety 
timer starts. Once the upper float switch closes the 90-second low water safety timer 
terminates. If the upper float switch remains open longer than 90 seconds, a 1-beep 
alarm sounds. The water valve and 1-beep alarm continue until the upper float switch 
closes.

To speed up the diagnostic process, the 5-minute ice purge cycle may be bypassed 
by pressing the "SERVICE" button on the control board after the gear motor starts. 
WARNING! Risk of electric shock. Care should be taken not to touch live 
terminals.

A 30-minute freeze timer starts once the upper float switch closes. Should the upper 
float switch fail to close again before the 30-minute timer terminates, the control board 
shuts down the icemaker and sounds a 5-beep alarm every 5 seconds. Also, when the 
lower float switch is open and the upper float switch is closed, the control board sounds 
a 5-beep alarm every 5 seconds. Both alarms require a manual reset. For further details, 
see "II.C.3.d) Feeze Timer (5-beep alarm)."

(1) 1-in-1 Drain Cycle: The 1-hour drain timer terminates, then the drain valve energizes 

for  seconds. This occurs once every hour when the 1-in-1 drain cycle is activated 
(S1 dip switch 4 in the "OFF" position (factory default)). This setting is recommended 
for optimum icemaker performance. The 1-in-1 drain cycle allows for maximum 
drainage of any sediment from the evaporator without interrupting the icemaking 
process.

(2) 1-in-12 Drain Cycle (optional): The 1-hour drain timer terminates, then the 

icemaker cycles down and the drain valve energizes for 10 minutes. This occurs once 
every 1 hours when the 1-in-1 drain cycle is activated (S1 dip switch 4 in the "ON" 
position (optional)). For further details, see "II.B.1.d) Drain Cycle." 

(1) Infrared Sensor: The ice level at shutoff may need to be adjusted depending on the 

dispenser agitation or dispense method. For a typical dispenser unit application, a 
100-second shutdown delay is recommended. Increasing the shutdown delay setting 
allows for a higher level of ice in the bin before the icemaker shuts down. When used 
with a standard Hoshizaki storage bin, any shutdown delay setting is acceptable. For 
further details, see "II.C.4.b) Infrared Sensor Shutdown Delay (S1 dip switch 1, , and 
3)."

(2) Mechanical Bin Control: The control board shuts down the entire unit within 

10 seconds when the mechanical bin control proximity switch opens (actuator paddle 
engaged). For further details, see "II.C.4.f) Mechanical Bin Control Shutdown Delay 
(S1 dip switch 8)."
