A. System Startup 

1.  Verify that the flow control knob, the refrigeration, 

and beater switches are in the “OFF” positions. 

2.  Turn on the Hopper Refrigeration. 

3.  Pour mix into the hopper pan. (Note: If using rerun 

mix, use at least 50% fresh mix to 50% rerun mix.) 

4.  Turn the beater switch “ON”. 

5.  Turn the flow control knob to the number “1 1/2” 

for approximately 3 seconds. Turn the knob back to 
the “OFF” position. This allows custard to mix to 
flush the sanitizer from the barrel to avoid instant 
freezing of the sanitizer in the barrel. 

6.  Place the custard slide on the threaded stud beneath 

the front plate and secure firmly with a wing nut. 
Aim the custard slide into a dipping cabinet or 
other suitable container for dipping.  

7.  Open the front gate. 

8.  Within several seconds, a few 

ounces of liquid mix and sanitizer 
will flow out of the custard outlet 
and into the dipping well. Discard 
this mix.  

9.  Turn the refrigeration switch on and wait approxi-

mately 2 minutes for a chatter noise. 

10.  Set the flow control 

know to “1/2-1” posi-
tion until frozen cus-
tard is seen at the cus-
tard outlet. Increase 
the mix by turning the 
flow control knob to 
gain the desired cus-
tard texture. 

Note: If a “growling” noise comes from the machine 
during this procedure, it may be an indication that 
there is not enough mix entering the barrel. In-
crease the flow slightly by adjusting the flow control 
knob on the front of the machine. Keep in mind that 
there are several minutes lag time between the in-
creased mix flow and the elimination of any 
“growling” noises

11.  Continue to run the mix into the bucket until it 

reaches the desired quantity. 

B.  Hold Cycle During Operation 

1.  Adjust the flow control knob to the “OFF” position. 

Wait approximately 1 minute. 

2.  Turn the refrigeration switch to the “Hold”. 

3.  When the frozen custard stops flowing, turn the 

beater switch to the “OFF” position and REMOVE 
KEY. Note: This should take approximately 2 min-
utes. 

4.  Clean out excess frozen custard from the custard 

outlet on the front plate to prevent dripping.  

5. Replace 

key. 

6.  Close the front gate. 

7.  Remove custard slide. 

C. Resuming Production During Operation 

1.  Turn the beater switch “ON”.  

2.  Turn the refrigeration switch “ON”. 

3.  Wait for a chatter noise, approximately 1 minute. 

Turn the flow control knob to the number “1-1 1/2” 
position. 

4.  Open the front gate completely. 

5.  When the custard appears, adjust 

the flow control knob to gain the 
desired custard texture.  

6.  Continue to run the mix into the dipping cabinet 

until you have the amount that you need.
