Running Product And Setting Pressures - Stoelting CC Series Owner's Manual

4 Connect the refrigeration lines from the line sets
to the machine. Access the machine from the left
or right service panel. The refrigeration system
has a charge of dry nitrogen. Use caution when
connecting the lines. Connect the suction line fi rst
then connect the liquid line. Run the refrigeration
lines under the machine. There is approximately
6" of clearance between machine and the fl oor.
The stainless steel legs are adjustable and can
raise the machine up to 7" off the fl oor if necessary.
Wrap the suction solenoid in a cold wet rag when
soldering to prevent damage to the solenoid. Also,
be aware of the electrical conduit inside custard
machine while soldering the refrigeration lines.
A liquid line dryer is supplied with the machine
and should be the last connection made in the
system. Use good piping techniques to keep the
system clean. Do not leave the lines open and
exposed for a long period.
5 After fi nishing the refrigeration connections,
connect power to the machine. Refer to
"B. Running Electrical Lines" for the proper
procedures. Check the rotation of the beater
shaft. When looking at the machine from the
front, the shaft needs to turn counterclockwise.
If the shaft is turning the wrong direction, shut off
power to the cylinder and switch the L1 and L3
wires. Check rotation again to verify the shaft is
rotating counterclockwise. Once verifi ed, tighten
the screws on the electrical box cover.
If the machine is single phase and the beater
shaft rotation is clockwise, then complete one
of the following procedures. Check rotation after
each procedure.
A. Change programming on variable speed drive
to reverse motor.
B. Change the T1 and T3 output leads going to
the motor from the drive.
C. Change the leads inside the motor electrical
box.
On CU-0010 and CU-0020 remote condenser
models, check the refrigeration systems for leaks.
When pressurizing the system, turn the refrigera-
tion switch to hold position to energize the suction
solenoid. Also, make sure that the shut off valves
are open on the remote condensing unit. Check
the refrigeration system with a minimum of 100 psi.
Make sure the system will hold the pressure for a
minimum of 2 hours.
Owner's Manual #513642
NOTE
After the leak check, connect a vacuum pump to
the system and evacuate it to 500 microns for a
minimum of 1 hour. Make sure the suction solenoid
and the shut off valves on the condensing unit are
opened. Perform a standing vacuum test. If the
vacuum deteriorates and continues to rise there is
a leak. Find it, repair it, and repeat the evacuation
procedure until the machine passes a standing
vacuum test. While the refrigeration system is under
a vacuum, insulate the suction line. Insulation is
needed up to the shut off valve on the condensing
unit. Use 3/8" tube insulation or insulation required
by local code.
8 Use good refrigeration practices to charge the
system with the required charge (see below).
Make sure the suction solenoid is energized and
that the shut off valves are open.

* Remote condensing units #285092 and #285093 ship from the factory with 20 lbs of
R-404a. Machines with remote condensing units #CU-0010 or CU-0020 require
24 lbs of R-404a supplied on-site.
Figure 2-2 Refrigeration Charges
Air cooled units require one remote condensing
unit (with compressor) per barrel. Condensing units
#285092 and #285093 ship from the factory with
20 lbs of R-404A for up to a 50' line set. Add 1 lb
of refrigerant for every 10' increase to the line set.
Line set max 100'. (Remote condensers CU-0010
and CU-0020 do not ship charged and require 24
lbs of R-404A).
F. RUNNING PRODUCT AND SETTING PRESSURES
FOR THE CUSTARD MACHINE
Complete the Custard Machine Start-Up and Train-
ing Checklist located with the spare parts kit or in
the back of this manual and send it to Stoelting.
1 Remove all spare parts from the hopper before
running product. Unwrap the parts and check for
damage. Refer to the list in the back of this manual
to make sure no parts are missing. The cylinders
need to be under a load to set the pressures. If
custard is not available, RV antifreeze can be
used as an alternative. Mix the RV antifreeze in a
concentration of 1 part antifreeze to 1 part water.
If RV antifreeze is used, the pressures will need
to be rechecked when custard mix is available.
The RV antifreeze will indicate that the system
is functioning correctly.
