2.2 RECEIVING THE CUSTARD MACHINE
A. Upon arrival, check the entire machine for any
damage that may have occurred during transit.
Withthemethodofpackagingused,themachine
should arrive in excellent condition. The carrier
is responsible for all damage in transit, whether
visible or concealed. Do not pay the freight bill
untilthemachine has been checked for damage.
Have the carrier note any visible damage on the
freight bill. If concealed damage or a shortage is
found later, advise the carrier within 10 days and
request inspection. The customer must place a
claim for damages and/or shortages in shipment
withthecarrier.Stoeltingcannotmakeanyclaims
against the carrier.
B. Remove the top of the crate using a hammer or
pry bar.
C. Remove the eight lag bolts from the machine
using a 1/2” ratchet. Remove the front and rear

the left and right crate walls.
E. Remove the plastic wrapping on the machine.
Remove the lower front and back panel on the
machine.
F. Removethefourlagboltslocatedinsidemachine
on the frame with a 9/16” ratchet. Remove the
two lag bolts that hold the skid together with a
9/16” socket.
G. If the machine has the shipping casters or if it is
water-cooled, the casters will be in a box located
in the hopper pan. A set of casters includes two
casters with locks and two casters without locks.
Screw the casters into the threaded holes and
tighten them using a pair of channel locks. After
installing the casters, knock out bottom 4” x 4” of
the machine skid.
NOTE
If the machine does not come with casters, install
the stainless steel legs. The legs are located in the
hopper pan on top of the machine. After installing
the legs, use a pallet jack to move machine into
place.
H. Put front and back panels on the machine.
2.3 MACHINE INSTALLATION
The following instructions are intended for a qualified
electrician/refrigeration specialist. Do not attempt these
procedures unless you are qualified.
A. RUNNING LINE SETS
NOTE
Ifthe machine iswater-cooled,proceed to“B.Run-
ning Electrical Connections”.
Line sets are not supplied with the machine.
Thelines sets can beinstalled priorto receivingthe
custard machine.
1 An air-cooled machine requires a remote
condensing unit and line set for each freezing
cylinder. The line sets must be 3/8” for the liquid
line and 7/8” for the suction line. When running
the line sets, each 10’ of vertical rise, install a
p-trap in the suction line. For every horizontal
line set run, pitch the suction line towards the
compressor to assist with oil returning back to
the compressor.
2 After the line set is installed, perform a thorough
leak test. Malfunctions of the equipment due
to leaks in the line set are not covered by the
Stoelting/Ross warranty.
CAUTION
Installation MUST be completed by a qualified
electrician/refrigeration specialist
Incorrect installation may cause personal injury,
severe damage to the machine and will void fac-
tory warranty.

Owner’s Manual #513642 8 CC Model Machines
3 Insulatethesuctionlinewithaminimumof3/8”wall
thickness or the wall thickness required by local
code. In humid areas, use thicker insulation. In
areasthatareexposedtoextremetemperatures,
insulate the liquid line to prevent excessive
sub cooling or heating of the liquid refrigerant.
Fasten all lines securely along ceilings, walls
and roofs. Avoid creating any type of kink in the
lines.TheStoelting/Rosswarrantydoesnotcover
malfunctions or capacity issues with equipment
caused by kinks in the line sets.
4 Usegoodpipingpracticeswheninstallinglinesets.
Sealtheendsofthelinesetsduringinstallationto
prevent exposure to the atmosphere and foreign
objects. Blow the lines out with dry nitrogen to
remove any debris that might be in the line sets.
When running line sets through a wall or roof,
mark the lines to eliminate confusion as to which
line set is running to which cylinder.
Example: Mark the liquid and suction lines with
the respective cylinder number. Facing the front
of the machine, cylinders are numbered left to
right.
5 When brazing the joints, purge dry nitrogen
through the lines to minimize oxidation of copper
inside of the lines. The Stoelting/Ross warranty
does not cover problems with the refrigeration
system that are caused by oxidized material in
the lines.
B. RUNNING ELECTRICAL CONNECTIONS
1 The machine requires a separate electrical
connectionforeachfreezingcylinder.Refertothe
nameplate on the machine for proper electrical
supply. Each freezing cylinder has its own
electricalsystemandcondensersoifonecylinder
fails, the other cylinder will still be operational.
NOTE
An air-cooled machine needs two circuits for each
freezing cylinder, one for the remote condensing
unit and one for the freezing cylinder.
Awater-cooled machine needs one circuit for each
freezing cylinder.
2 Theelectricalboxesarelocatedbehindthelower
front panel. Labels indicate which cylinder each
electrical box powers. No pigtails are supplied
with the machine or condensing unit.
3 If the condensing unit is on the roof or ground,
a quick disconnect box needs to be installed to
provide power.
4 Do not turn on the power to the machine or
the condensing unit until the refrigeration lines
have been connected and the system has been
chargedwithrefrigerant.Labelthecircuitbreakers
with information regarding which cylinder and
condensing unit the breaker is designated for to
preventconfusion if powerever needs tobe shut
off.
5 When connecting power to the machine, run the
line under the machine and through the bottom
of the electrical box. Remove the electrical box
cover by loosening the four screws. The screws
do not have to be removed. Connect the power
to the terminal strip. The terminal strip is labeled
L1,L2,L3,andGND.Afterconnectionsaremade,
place the cover on the electrical box, but do not
tighten the cover (for single-phase machines the
cover can be tightened). The electrical box may
need to be accessed when checking for proper
rotation of the motor.
C. PLUMBING CONNECTIONS
1 On water-cooled machines, the water inlet is a
standard garden hose connection and the water
outlet is 5/8” OD copper tubing. The connections
are located at the back of the machine. Remove
the rear panel to access the connections. Run
the plumbing under the machine frame. Water-
cooled machines use approximately 3 gallons of
75°F water per minute when the compressor is
operating. The machine does not use any water
when not in use.
2 The machine is equipped with a dipping trough
that requires a water inlet line and a drain line.
The water inlet has 1/2” NPT close nipple fitting.
Install a shutoff valve in the water inlet line. The
drain connection is 1-1/2”. Run a drain line from
the trough to a drain on the floor. Leave enough
slackinthedrainlinesothatthelowerfrontpanel
can be easily removed for service.

Owner’s Manual #513642 9 CC Model Machines
D. RECEIVING AND INSTALLING REMOTE
CONDENSING UNITS
NOTE
The remote condensing units may be sent prior to
delivery of the freezer.
The freezer requires one remote condensing unit
per cylinder.
Remote condenser models 285092 and 285093
are shipped from the factory charged with 20 lbs
of R404a refrigerant.
Remotecondenser models CU-0010 andCU-0020
are shipped from the factory without a refrigerant
charge.
1 Upon arrival, check the entire remote condenser
units for any damage that may have occurred
duringtransit.Withthemethodofpackagingused,
theremote condensersshouldarriveinexcellent
condition.Thecarrierisresponsibleforalldamage
in transit, whether visible or concealed. Do not
pay the freight bill until the remote condenser
units have been checked for damage. Have the
carrier note any visible damage on the freight
bill. If concealed damage or a shortage is found
later,advisethecarrierwithin10daysandrequest
inspection. The customer must place a claim for
damages and/or shortages in shipment with the
carrier.Stoeltingcannotmakeanyclaimsagainst
the carrier.
2 Remove cardboard covering off the condensing
units.
3 Placethecondensingunitsintheirpredetermined
location, either on the roof or on the ground. A
crane or forklift will be needed if the units will be
placed on a roof. The condensing units weigh
approximately 200 lbs. each.
4 Using ratchet with a 1/2” socket, remove the two
lag bolts that secure the condensing unit to the
pallet.
5 Place the condensing units on 4” x 4” treated
wood or similar material so that the units are not
sitting directly on the ground or the roof. Secure
the condensing units to the 4” x 4” using lag
bolts.Adheretoalllocal,state,andfederalcodes
governing this type of installation. Some areas
have specific “hurricane-proof” requirements
for roof installations. Allow at least 3 feet of
clearance on the air intake and discharge sides
of the condensers. Do not set the condensers
so that one is blowing air directly into the other
condensing unit. The ideal set up is to have all
the condensing units set in a row (Fig. 2-1).
NOTE
On CU-0010 and CU-0020 remote condenser
models, use an Allen wrench to open the shut off
valves and release some of the nitrogen charge in
thecondensingunit.The shut off valvesare located
onthe outside of thecondensing unit.If no nitrogen
is present then the unit needs to be leak checked
prior to connecting the refrigeration lines.
7 Braze the suction line and liquid line from the
line sets to the condensing unit. When brazing,
wrap the shut off valve with a cold wet rag. If the
valve is not wrapped, damage to the valve may
result. When installing the suction line, angle it
towards the condensing unit so that oil can flow
back towards the compressor.
8 Usegoodpipingpractices.Keeppipesascleanas
possible.Donotletanydebrisorcoppershavings
get inside system otherwise the refrigeration
valves may not work properly.
E. SETTING IN PLACE AND MAKING MACHINE
CONNECTIONS
1 Rollthemachine into the desired location. Leave
adequate space around the machine for the
removalofservicepanels.Removetheleft,right,
back and lower front service panels.
NOTE
After the refrigeration lines are connected, air-
cooled machines cannot be moved.
2 Useapalletjack or floor jackto lift the frontof the
machine, remove the two shipping casters with
a pair of channel locks, and install the stainless
steellegs.Makesurethelegsareadjustedallthe
way in, and screw two of the legs into the frame.
Secure them tightly using channel locks. Repeat
with the back of the machine.
NOTE
Ifthemachineiswater-cooled,casters are standard
with machine.
3 Accurate leveling is necessary to ensure
proper operation. Place a bubble level on top
of the machine at each corner to check for level
condition. If adjustment is necessary, level the
machine by turning the bottom part of each leg
or caster in or out.
To finish installing a water-cooled machine,
proceed to “F. Running product and setting
pressures for the custard machine”.

Wrapthesuctionsolenoidinacoldwetragwhen
solderingtopreventdamagetothesolenoid.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 finishing 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 verified, 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.Changeprogrammingon variablespeeddrive
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. NOTE
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
therefrigeration system witha minimumof 100psi.
Make sure the system will hold the pressure for a
minimum of 2 hours.
After the leak check, connect a vacuum pump to
the system and evacuate it to 500 microns for a
minimumof 1 hour. Makesure thesuction 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
vacuumtest.Whiletherefrigerationsystemisunder
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.
NOTE
Air cooled units require one remote condensing
unit(withcompressor) 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).

1 Remove all spare parts from the hopper before
running product. Unwrap the parts and check for
damage.Refertothelistinthebackofthismanual
tomake sure nopartsare missing.The cylinders
need to be under a load to set the pressures. If
custard is not available, RV antifreeze can be
usedas analternative.Mixthe RVantifreeze ina
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.

wrench. Connect a gauge to the suction line at
the hopper and adjust the hopperAXV 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
fine-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 flavoring 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).

7 When testing is done, take the cylinders apart
and clean the custard machine. Refer Section 3
for details.
