Model PH61 Operating Procedures
Disassembly
Note: Failure to remove the parts, brush clean, and
re-lubricate the parts, will result in damage to the
machine. These parts must be removed every 14
days or the machine will lock out and will not
operate.
Be sure the power switch is in the OFF
position. Failure to follow this instruction may result
in severe personal injury from hazardous moving
parts. (See Figure 78.)
Figure 78
In order for the control to recognize that the unit has
been brush cleaned, the following criteria must be
met.
S All freezing cylinder and hopper
temperatures must be above 60_F(16_C).
S The mix out and mix low probes must not be
satisfied.
S The power switch must remain in the OFF
position for at least 5 minutes.
Note: These criteria must be met
simultaneously. These criteria will be met when the
unit is properly brush cleaned.
The following screen is displayed if the machine is
not in a brush clean state. (See Figure 79.) If any of
the requirements for a brush clean have not been
met, the time displayed will remain at 5:00 minutes.

When the power switch is set in the ON position, the
system mode of operation screen is displayed. In
this example, the machine is ON, but no mode of
operation has been selected. The second line of the
display indicates whether there is a sufficient supply
of mix in the hopper or if there is a LOW or OUT mix
condition. The third line of the display shows the
temperature of the mix hopper. After pressing the
AUTO key, the last line of the display shows the
month and date (MM = month, DD = day) that the
machine needs to be disassembled and brush
cleaned. (See Figure 81.)
