Important
Failuretocloselyfollowoperationalandmaintenanceprocedures
may result in damage to the unit and/or void your warranty.
Coldelite Corporation will not be responsible for any machine
not properly maintained.
In the event this unit should malfunction, please contact your
Coldelite Distributor or an authorized service agency.
PART I
INSTALLATION
Before starting this procedure, make sure the shipping case
doesnotshowanyevidenceofhavingbeendropped,tampered
withorabusedinsuchawayastoindicatethatitscontentsmay
have been damaged in transit.
IMPORTANT:Shouldtheoutsideoftheshippingcasegiveany
indication of possible hidden damage, state this on the bill of
lading before signing. Contact the carrier immediately and
requestaninspectionofdamage.Ifthisprocedureisnotadhere
to,youwillforfeityourrighttofiledamageclaimandberesponsible
for subsequent repair costs.
A)Uncrating
Proceed, as follows:
1) The case is secured to the skid with plastic strapping.
When you cut this strapping, do it with caution, as it may
spring out. Remove case by lifting it straight up and away
from the machine.
2) Thefreezerisalsosecuredtotheskidwithplasticstrapping.
Exercise caution and cut this strapping to free the machine
from the skid.
3) Remove the single screw at the bottom of each side panel.
Remove the panels by sliding upward slightly, then
pull outwardatthebottomandallowthepaneltoslide
down. The protective plastic coating which is
laminated to the panels can now be removed by
simply peeling off.
B)Positioning the Machine
1) The freezer is shipped without legs installed. To install
the legs, lift the freezer and screw the four legs into the
bottom of the frame at each corner. When the freezer is
placed in the desired location, it must stand level. Level
the freezer by turning the bottom part of each leg in or
out. Check for level condition by placing level on the top
of the freezer at each corner.
NOTE: Accurate leveling is necessary for correct drainage of
freezer barrel and to insure correct over-run.
Figure 1
Clearances Required for
Air Cooled Models
2) The freezer is now ready to be positioned onto your
counter. The counter must be capable of supporting 180
lbs. and should be vibration free. Reinforce it, if necessary.
Remember when choosing a location, if your unit is air
cooled, proper air flow will need to be maintained. Allow
at least 8 inches on left side and a minimum of 6 inches
between the right side of the machine and any obstruction.
(Ref. Fig. 1).
Note: If these clearances are not maintained, the production
capacitywillbereduced,cyclingwillincreaseandthepotential
will exist that the machine will stop completely.
3) It is necessary to clean the condenser each month to
eliminate dust, paper, etc. which may obstruct it, damaging
the proper functioning of the machine.
4) The machine should also be within six feet of the power
supply (a plug and receptacle or unfused disconnected).
5) Position the machine for easy accessibility for cleaning,
servicing and maintenance.
6) Position the machine away from direct sunlight. For every
2°F over 68°F, the machine’s performance will decrease
by approximately 1%.
7) Once the machine is set in position, it should be leveled
as accurately as possible.

C) Electrical Requirements
Allwiringinstalledtooperatethisfreezermustbeinaccordance
with the National Electrical Code and/or local electrical codes,
rulesandregulations.Themachinemustbeproperlygrounded.
Itis recommendedthe powersupply beinstalled bya licensed
electrician.
Voltage UC 511: 115 Volts
Total Running Amperage FLA: 18 Amps.
Fuse Size: 20 Amp. Max.
Wire Size (50 Ft. Max.): # 10
Power Supply must be adequate to meet requirements at all
times.Voltagefluctuations,withthemachineinoperation,should
not exceed ± 5% of the normal or rated voltage.
Adequate Wiring must beprovided with respectto wire sizeor
gauge.Unless otherwiserequiredbythelocalElectricalCode,
thesamesizewiregaugeatthemachinejunctionboxshouldbe
used for direct power line. A separate circuit breaker with
adequate fuse protection should be employed.
An unfused disconnected switch or a properly sized plug and
receptacle within 6 feet of the freezer, is recommended.
Coldelite freezers are equipped with protection for the beater
motor. Should the line voltage drop, or in the unlikely event a
short circuit occurs, the overload protector will automatically
disconnectthestarterandthemachinewillstopimmediatelyso
that no permanent damage can be caused to the motor.

Electrical Connections (Ref. Fig. 5)
Having removed the right side panel, the machine’s wiring
connection box can be found on the bottom of the frame and is
labelled “Connect Power Line Here”.
The power line is first passed through the access hole located
atthebottomdeckdirectlybelowthewiringconnectionbox.The
powerlinemaythenbeconnectedtothemachine’spowerlines
and wiring connection box. Upon completion, the power line
shouldbefastenedtothewiringconnectionboxwithappropriate
electrical hardware.
In all installations, the machine must be properly grounded.
Since all high voltage components (controls are 24 volts) are
connected by means of flexible conduit, or cord, adequate
groundcontinuityisassuredbyrunningandfasteningaground
line to the machine junction box ground lug. (Ref. Fig. 5).

Warning!
Never use anything other than the O-RING EXTRACTOR to
remove o-rings as damage to the o-ring and/or part can result.
3) Clean carefully the mix level device.
4) Loosen and remove the two (2) dispensing head retaining
knobs. The knobs are removed by turning in a counter-
clockwise direction.
5) Remove the dispensing head by pulling it straight towards
you and away from the machine.

Continue disassembly by removing the beater IDLER. Pull
forward until the grooved portion of the shaft lines up with the
opening at the front of the beater/auger.
Finally, remove the beater/auger END PUSHER by pulling
straight and away from the beater. Dismount the scraper by
pulling it away from its housings.
9) The machine is now completely disassembled. The parts
should now be washed, rinsed and sanitized.

PART IV
ASSEMBLING THE FREEZER
Once the parts have been washed, rinsed and sanitized, the
freezer is ready to be re-assembled. Prior to beginning the re-
assemblyprocedure,sanitizeyourhandsbysubmerginginthe
sanitizing solution. Begin to re-assemble as follows:
A) Assembling the Beater/Auger
1) First, re-assemble the beater/auger assembly. Begin by
gatheringthefivepartsneededtocompleteeachassembly:
A) plastic “END PUSHER”, B) BEATER/AUGER, C) IDLER,
D) rubber, beater LIP SEAL, E) BLADE.
2) Mounttherubbersealontothescraperbykeepingthehead
opposite to the groove.
3) Insert the scraper into the beater pins. Fasten the end
pusher. When installed correctly, the scraper should move
freely up and down, but should not come out away from
its seat.

5) Turn the dispense head over and install the 4" diameter
O-ring into O-ring groove located in the back of the head.
Lightly lubricate the O-ring with the sanitary lubricant.
2) First, remount the end piston O-rings onto the end pistons.
Simply roll onto the piston until they drop into the O-ring
notches.
3) OncetheO-ringshavebeenmounted,liberallylubricatethe

PART V
SANITIZING THE FREEZER
Prior to install the machine with your soft serve product, the
machine must be sanitized. The frequency of cleaning and
sanitizing cycles must comply with local health regulations.
If uncertain about local regulations, contact your local Board of
Health.
Sanitizing the machine is most important. This procedure will
retardthegrowthofbacteriaandinsureexcellenttestresultson
yourproductwhenexaminedbylocalHealthand/orAgriculture
Departments.
To begin, you will need a clean pail, sanitizer (sample packets
includedinthestart-upkit),spatula(includedinstart-upkit),and
brush (plastic bristle).

2) Pull the gravity feed tube out of the mix tank hole and lay it
down in the tank. This will allow the cylinder to completely
fillwith thesanitizing solution.
3) Push selector button 571.2 to select the BEATER position.
Let the machine run for 30 seconds.
