2 Disassemble, clean and sanitize each freezing
cylinder. Refer to the Section 3 for proper
instructions.
3 After assembling and sanitizing the machine, add
custard mix to the hopper. Follow the instructions in
the Section 3 to start freezing the custard (run one
cylinder at a time to set the pressures). Connect
gauges to the suction line and the discharge line.
When product starts coming out of the faceplate,
locate the low pressure gauge on the front of the
machine and set the AXV to 30 psi. Remove the
white plastic cap from the AXV and turn the valve
counterclockwise to decrease the pressure or
clockwise to increase the pressure. Turn the valve
1/4 turn at a time and wait at least 1 minute before
making another adjustment. Connect a gauge
to the suction line at the compressor and make
sure the pressure is 25 psi. Adjust the crankcase
pressure regulator (CPR) if the pressure is not
correct. Remove threaded brass cap on the front
of the CPR and adjust the valve with a 5/16” Allen
wrench. Connect a gauge to the suction line at
the hopper and adjust the hopper AXV to 55 psi.
4 Check the faceplate to see if the custard is at the
desired texture and temperature. The standard
normal serving temperature of frozen custard
coming out of the machine is 18°-21°F.
5 Set the pressures for the remaining cylinders.
NOTE
If the machine is water-cooled, the discharge pres-
sure was already set at the factory. Run custard
mix through the machine to double-check and
fi ne-tune the discharge pressure for the particular
mix being used.
The remote condenser unit has a head pressure
control set for 245 psi.
Custard mixes that use an extract fl avoring will
also run differently. Try different pressure settings
by adjusting the AXV. Adjust the pressure setting
between 28-32 psi (the machine will not operate
correctly if the AXV is set lower than 28 psi).
6 If the machine is equipped with the lemon ice
option, set the lemon ice AXV. The lemon ice option
is designated for one cylinder (right cylinder). With
the system still running product, turn the lemon
ice switch on. The AXV is located behind the front
panel. Set the lemon ice AXV for 38-42 psi.
7 When testing is done, take the cylinders apart
and clean the custard machine. Refer Section 3
for details.
