Initial Start Up
1. Turn the water supply on.
2. Switch the electrical power on. Confirm voltage is
correct for the model.
3. Push and release the On button. The machine will
start up in about two minutes.
The liquid line valve will open and liquid refrigerant
will flow into the machine. For the units connected to
a dedicated condensing unit, the resulting increase in
suction pressure will start the condensing unit and the
condensing unit will begin discharging warm air from
the remote condenser. After about 5 minutes, ice will
begin to drop into the bin or dispenser.
4. Check the machine for unusual rattles.
5. Tighten any loose screws, be sure no wires are
rubbing moving parts. Check for tubes that rub.
6. Check suction pressure, adjust EPR setting. As
shipped the EPR valve should maintain low side
pressure at about 36 PSIG + or - 2 PSIG.
Note: Machines will operate and make ice at the
factory EPR setting. For optimum performance, adjust
the EPR to the settings in the chart below:

7. Fill out the warranty registration form and either
file it on line or mail it.
8. Notify the user of the maintenance requirements
and whom to call for service.
Maintenance
This ice machine needs five types of maintenance:
• Remote condensing units need their condenser coils
cleaned regularly.
• All models need scale removed from the water
system.
• All models require regular sanitization.
• All models require sensor cleaning.
• All models require a top bearing check.
Maintenance Frequency:
Scale removal. At least twice a year, in some water
conditions it might be every 3 months. The yellow De-
Scale & Sanitize light will switch on after a set period
of time as a reminder. The default time period is 6
months of power up time. There are 4 available time
period intervals: 1 year, 0 or disabled, 6 months or 4
months.
Sanitizing: Every time the scale is removed or as
often as needed to maintain a sanitary unit.
Sensor Cleaning: Every time the scale is removed.
Top bearing check: At least twice a year or every time
the scale is removed.
Maintenance: Remote air cooled condenser
The condenser fins will occasionally need to be
cleaned of leaves, grease or other dirt. Check the coil
every time the ice machine is cleaned.
Maintenance: Exterior Panels
The front and side panels are durable stainless steel.
Fingerprints, dust and grease will require cleaning
with a good quality stainless steel cleaner
Note: If using a sanitizer or a cleaner that contains
chlorine on the panels, after use be sure to wash the
panels with clean water to remove chlorine residue.
Maintenance: Water filters
If the machine has been connected to water filters,
check the cartridges for the date they were replaced
or for the pressure on the gauge. Change cartridges
if they’ve been installed more than 6 months or if the
pressure drops too much during ice making
