How the HFO10 Machine Works 

 Warning: 

Only service personnel experienced and certified in refrigeration and qualified to work 

with high-voltage electrical equipment should be allowed to install or work on this Tube-Ice® machine. 

Principles of Operation 

Manual operation of the machine is controlled by the three-position 

Clean/Off/Ice

 selector switch and the 

Start

 

and 

Stop

 buttons located on the control panel of the freezing unit.  

 

Figure 1: Control Panel Door 

Automatic operation is controlled by the standard ice bin thermostats, which stop and start the ice maker based 
on the level of ice in the storage bin.  

The type of ice produced, cylinder or crushed (optional), is determined by how the machine cutter is set up.  

The unit will only stop when a thawing (harvest) period has been completed, whether by the 

Clean/Off/Ice 

selector switch or the ice bin thermostat. To stop the machine instantly, push the 

Stop

 button. To restart the 

machine, push the 

Start

 button. 

The 

Clean/Off/Ice

 selector switch must always be set in the 

Ice

 position during normal ice-making operation. It 

is set in the 

Clean

 position only when the equipment needs cleaning. 

Air-cooled machines have a solenoid valve, sometimes referred to as the X valve, in the compressor discharge 
line and a check valve in the liquid return line to the receiver. These valves prevent the migration of refrigerant 
when the machine is not operating. The X valve is always open when the compressor is running.
