Start Up
1) Open the water supply to the ice machine and check for water leaks.
2) Switch the power on at the wall socket (Green light on)
3) The machine will enter the startup cycle for 5 minutes filling the water
trough. Check to see water is trickling into the water trough by lifting fingers.
4) After the 5-minute filling / draining cycle is completed, the machine will start
up in the freezing cycle (Yellow light) The refrigeration system will run, and
the condenser fan will thermostat on and off during the cycle. The machine
will run for between 17 to 24 minutes making ice (depending on ambient
and water temperatures)
5) Once the ice is made and fully formed, the machine will go into a harvest
cycle until all the ice cubes have dropped into the ice storage bin.
6) When the ice bin fills, ice will touch the ice bin sensor probe on the right side
of the ice bin (EC-47-57-87-107-127 models) and will shut down the
machine. For EC-177 model, the ice bin shut off has a beam sensor, when ice
blocks the beam, it shuts off the ice machine (Yellow light)
7) When ice is removed from the bin away from the sensors, the machine will
start up again and start making ice.
8) After the machine has completed 4 cycles, open the ice storage bin and
inspect the freshly made ice cubes. They should have a small indentation at
the bottom of the cube like in diagram below.

Maintenance, Cleaning and Sanitizing Instructions
To ensure your Scotsman ice machine operates effectively, efficiently and in peak
performance, the ice machine requires regular maintenance, cleaning, and sanitizing.
As per Health and Safety requirements in Australia, it is the owner’s responsibility
to ensure the ice machine is installed, maintained, and regularly cleaned as per the
manufacture’s specifications. Ice is classed as a food product so the machine must
be regularly inspected and maintained to ensure the ice is clean, safe, and fit for
human consumption.
Cleaning Schedules
All Scotsman ice machines require a general clean and sanitize procedure every two
weeks to a month (depending on the location of the machine)
All Scotsman ice machines require a major strip down, a deep clean and sanitizing
twice a year by a qualified technician (depending on the location of the machine it
may require more frequent cleaning)
General Weekly or Monthly Clean
Shut down the machine, remove the air filter element and inspect and clean with a
soft bristle brush or wash air filter with warm soapy water and dry, replace the air
filter. Remove all the ice from the storage bin, depress and remove the steel wire clip
and rubber cup from the base of the water trough and clean. (Regularly clean the ice
bin level sensors on the EC–177 models as below)
Clean the inside of the ice bin thoroughly with a cleaner and then rinse off. Sanitize
the ice bin using Moffat ice machine sanitizer and then rinse off with water.
Pour 1 liter of warm water and Moffat ice machine sanitizer down the ice bin drain
to keep drain and drain hoses clean and free of bacteria. (Mixture 10 parts water

keep the drain and drain hose clean and free of bacteria. Allow the machine to make
2 x batches of ice and inspect the ice cubes. Discard the first 2 drops of ice to ensure
the ice is clean and free of any cleaner or sanitizer.
Ice Machine Fault Finding Check List
For ice machine fault finding, first check the 12 Point Checklist in this manual, then
check below points before calling Moffat Service.
Slow production - check water tap is on full, check the water filter strainer is clean on
the inlet valve (remove hose to check) check water filter. Is there any equipment
generating heat next to the machine? (refrigerators, dishwashers, fryers, ovens)
Check there is cool air ventilation around the machine.
Deformed ice cubes –check water spray system is fitted correctly; check spray
nozzles are clean and not blocked. Has the machine had regular cleaning and
sanitizing? when last was the machine striped and cleaned professionally?
Water Leaks –Has the machine been sanitized regularly? A dirty blocked up machine
will cause water leaks, check water filter, water hoses and drain hoses for water
leaks. Check the drain hose is securely located in a vented drain or tundish.
Ice machine error codes are located inside the front door panel.
How an Ice Machine Works
An ice machine works by transferring heat from the water inside the ice machine, to
the condenser through the refrigeration system. The condenser fan exhausts this
heat out and away from the ice machine. The transfer of heat is so efficient that it
freezes the water into the evaporator mold making ice cubes.
NOTE: If the airflow is restricted or blocked on either the air inlet or air outlet vents
the heat transfer process will not take place. This means the ice machine will make
little or no ice. It requires good cool airflow through the machine to operate
effectively and efficiently.
Ensure there is NO heat generating equipment next to or close by the ice machine.
The hotter the work area and water temperature is going into the machine, the less
ice the machine will make.
