Introduction; Operation; Events That Can Interrupt Normal Production - Dometic ESKIMO ICE Operation Manual

iNtroDuctioN

This operation manual provides information for self-contained and remote Eskimo Ice
Systems using digital controls. please refer to Eskimo Ice Manual L-2448a for installa-
tion of the self-contained system and L-2448B for installation of the remote system.
Please Note: the supplied main cartridge filter must be installed or the
warranty will be VoiD!

Applying Power - When power is first applied, the
display will light all LED's for 2 seconds, then go blank
for 1 second, then show software revision b-16 for 2
seconds. The unit will then go to the last state it was
in before power was disconnected. The power LED
will remain lit anytime power is applied.
on/off - Press the On/Off button to toggle between
Off and ICE production. dLY will appear in the display
and the unit will begin a startup routine. ICE will
appear in the display when production begins.
ice Bin sensor - When the ice bin is full, the unit will
stop ice production and the display will show Full.
operational LeD's - Ice Flow, Water Flow, High
Pressure, and Low Pressure are trouble lights on the
display and will light if a fault occurs and a fault code
will be displayed. Comp and Auger are status lights
and show operation of these systems. Full is also a
status light that is on whenever the ice bin is Full.
operational information - Compressor current,
Auger current, and AC voltage can be viewed while
the unit is in operation. Simultaneously press and
release the On/Off and Function buttons. CA will
appear in the display and after 5 seconds, a value
indicating the compressor current in amps will show.
Press Function to change to AA and auger current in
amps will display. Press Function again and AC line
voltage will display. Press the On/Off button to exit
from this feature.
Fault history - History of faults that occur can be
viewed from the off setting. Press and hold the On/Off
button for 3 seconds. This will enter the fault history
log. The display will indicate H 1. Press the function
button to scroll through the events recorded in the log.
The unit will record up to 16 events. While viewing, the
display will alternate between the fault mnemonic and
the event number. To exit the history mode, press the
On/Off button. The unit will also exit the history log in

30 seconds if no key is pressed. Faults are recorded
in the order they occur, most recent to oldest.
events that can interrupt normal
production
If trouble occurs during operation the fault codes
defined below will be displayed. Trouble LED's will
be lit for High Pressure, Low Pressure, Water Flow,
and Ice Flow. The unit will restart once the fault is
cleared or repaired. Excessive faults will result in
the code flashing on the display called a lockout. A
lockout may be cleared by pressing the On/Off button
to turn the unit off then on again, by pressing the reset
switch or pressing the function button.
LPF - Low Pressure Freon. If the Low Pres-
sure Freon Switch is open during production for 60
seconds, the display will show LPF fault and the Low
Pressure LED will light. The compressor delay is then
activated for restart. The auger will continue to run
for the duration of the auger delay. At the end of the
compressor delay the unit will show dLY beginning the
restart routine. This switch is checked at the start of
a cycle and during operation. The compressor delay
begins from the moment the switch is opened. Three
faults in a 30 minute period will result in a lockout.
LPF can be caused by, Low refrigerant levels, Seawa-
ter below 50°, or faulty low pressure switch.
hPF – high Pressure Freon. If the High Pressure
Freon Switch is open during production for ~500ms,
the display will show HPF fault and the High Pressure
LED will light. The compressor delay is then activated
for restart. The auger will continue to run for the dura-
tion of the auger delay. At the end of the compres-
sor delay the unit will show dLY beginning the restart
routine. The compressor delay begins from the
moment the switch is opened. The maximum number
of faults that can occur in 30 minutes is set for three
by default. HPF can be caused by lack of seawater
flow due to a dirty strainer, pump being airlocked or
seawater lines in need of maintenance.
