Installation manual

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.
4 Those units connected to a dedicated
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.
5 Check the machine for unusual rattles.
Tighten any loose screws, be sure no wires
are rubbing moving parts. Check for tubes
that rub.
6 The EPR valve should maintain low side
pressure at a minimum of 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:
Model Number
Scotsman
Condensing Unit
Rack
N0622L / F0822L Full open 30 PSIG
N0922L / F1222L Full open 30 PSIG
N1322L / F1522L Not specified 26 PSIG
Superheat will be 12
o
F, + or - a few degrees.
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.
