System Controller; Initial Start Up - Scotsman Frimont CME1356 Mode D'emploi

8. Has the bin control been installed?
9. Is the water pressure adequate?
10. Have the drain connections been checked for leaks?
11. Has the bin interior been wiped clean or sanitized?
12. Have any water filter cartridges been replaced?
Component Description and Function
Reservoir: Contains the water for ice making.
Water Inlet Valve: Opens to allow water into the reservoir.
Water Level Sensor: Controls the size of the ice cube by
measuring how much water is used in a cycle. It consists of
a float, stem and electric eye. The stem will move slightly
when the pump is on, this is normal. As the machine makes
ice the reservoir water level will fall and the visible portion
of the stem will slide down through the slot in the sensor
body.
Evaporators/Freezing Compartment: Location of the
evaporators. Ice forms on the evaporators and is released
when warmed up during the harvest cycle. The freezing
compartment is fully insulated for maximum efficiency.
Cube Deflectors: The slots in the inclined deflectors let the
water falling from the evaporators back into the reservoir,
but when ice falls during harvest, the ice slides off into the
bin.
Refrigeration Service Access Valves: Only to be used by a
certified technician. Allows access to the refrigeration
system for diagnostic information.
Water Pump: Forces the water from the reservoir to the top
of the evaporators. The motor is separated from the reservoir
water to minimize contact with the water.
Hot Gas Valve: Closed during freeze, it opens during
harvest to divert hot discharge refrigerant gas into the inlet
of the evaporators.
Purge Valve: Opens during the early part of the harvest
cycle to drain the reservoir.
Ice Sensor: A photo-electric eye set, located at the front and
back of the cube port.

System Controller

Indicator Lights:
Bin Full: On when bin is full, goes on and off as ice falls
during a harvest cycle.
Freeze: On when the unit is in the Freeze cycle, blinks when
a freeze mode is pending.
Harvest: On when the unit is in the Harvest cycle.
Clean: On when the unit is in the Clean cycle, blinks when
preparing for a clean mode.
Off: On when the unit has been switched off, blinks when
the machine is preparing to shut off.
Water: On when the controller has identified a problem with
the water system.
Refrigeration: On when the controller has identified a
problem with the refrigeration system.
Cycle Definitions:
Freeze: The refrigeration system is operating to remove heat
from the evaporators. The compressor, fan motor (if air
cooled) and water pump are ON.
Harvest: The refrigeration and water systems are operating
to harvest the ice cubes. While the compressor is on for the
full cycle, the water pump will be off at the beginning and
inlet water valve will switch off before the end.
Clean: The Inlet Water Valve opens to fill the reservoir. The
Water Pump starts. The Clean indicator light is switched
ON. A manually initiated rinse flushes the system.

Initial Start Up

1. Remove the front panel.
2. Locate the System Controller.
3. Switch on the electrical power. Note that the controller's
indicator lights all flashed on briefly.
4. Open the water supply valve.
5. Push and release the Freeze cycle push button (the Freeze
indicator light will blink until the compressor starts). The
next several operations are automatic.
Initial Start
The Freeze light will begin to blink.
The Hot Gas Solenoid valve will be open.
The Purge valve will be open.
