FOREWORD
_ __ . . ---
Thank you for stlectir~gCOLDELITE to meet today's fast
growing demands. your
COI,DELIT~ freezer has been manu-
factured at
the most modern freezer manufacturing plant
in the U.S.A., our I,od~, New Jersey facility, utilizing
the most advanccd cqul:)mcnt and technology available in
the industry.
We, at coldelite, take great pride and
care in the manufacture of each and every freezer, using
only the finest co7,poncnts available, to provide you with
years of trouble-
f ree operation.
Over twenty-flve ycars of cxpcrlence in the manufacturing
of dis~ensrngequik)ment
hal~c gulded us ln the preparation
of thls Operation and Service Manual. PLEASE READ IT
CAREFULLY. Keep it for future reference and most of all,
follow the rnstructlons from the very time your machine
is delivered.
On the following p3ges, you
wlll find important inforrna-
tion and procedures whlch describe the proper installation,
sanitizing, operation and maintenance
of your COLDELITE
machine. b'e feel certaln that your full compliance with
these instructions will assure you of excellent performance,
trouble-free operatior, and a profitable business for years
to come.
NOTICE
Failure to closely follow set-up.and maintenance procedures
can 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.
WARNING
EXTRE5iE CARE

INSTALLATION

PART I
--
A - UNCRATING
-
Before starting this procedure, make sure the carton
does not show evidence
of having been dropped, tampered with
or abused in such a way as to indicate that it contents may
have been damaged in transit.
IMPORTANT - In the event the outside of the Carton should
grve any
indication of possible hidden damage, state this
on the
bill of lading before signing. Contact the carrier
immediately and request an inspection of the damage. If
this is not done, you are responsible and must pay for any
repairs required.
1) Proceed with the uncrating, as follows:
a)
If the.unit arrives in a carton, it is held by plastic
strapping. When you cut this strapping, do it with caution
as it may spring out. Then remove the cover, and lift the
carton straight up.
b) If the unit arrives in a crate, the crate is nailed
around the
bottom perimeter. Remove all nails. The crate
has corner supports, three of which are riveted
and the other
one, stapled. By removing the staples, you
will be able to
slide the crate off the skid. The crate may also be lifted
vertically, if there
is sufficient head room.
C) Inspect the machine thoroughly for damage before re-
moving the skid. If the machine
is damaged, do not remove
the skid. Contact the carrier immediately, file your
claim,
and save all the crating material.
2) Remove the two side drip chutes. Remove the
screws hold-
ing the side panels. The panels may now be removed by
simply
sliding them upward slightly, then pulling outward at the bot-
tom, allowing the panel to slide down. The machine is held to
the skid by bolts and nuts on the left and right side. Remove
these bolts and the skid.
Check inside the hopper for accessories and parts, which
should be removed and unpacked.

1) The freezer is now ready to Lc placed ln its location.
In selecting the location, consideration should be given to
the following:
a) If the-unit is alr cooled, allow at least 20 inches from
the rear
of the machine to the wall, so that there is a flow
of air circulating
around the unit.
b) If the unrt 1s w~~ter cooled, it should be located close to
the water supply
and a drain wlthin six feet.
C)
The ~achl ne should also kc close to the power supply, a
plug, and recc--ptacle or unfused disconnect and within six
feet.
d) Posrtlon the machine for casy accessibility for cleaning,
servicing and malntcnance.
e) Protect the machine from the sun. For every
2°F over 68OF,
the mach 1 ne ' s pel- forri.-jncc w I 11 ciccrcase by 1%.
f) Oncc the mhchine is set in its position, it must be leveled
as accurately as possible.
g) Free the compressor by loosening the retaining bolts and
renovincj the fastening blocks, if any. The compressor should
float freely
on its mountlny qromet. Clearance between rubber
grommet and rf-atdining
bolts should be approximately 1/16 of an
inch.
h) Place the rnackiine
in
a conspicuous area to be readily seen
by the public. This will lncr-ase the demand for ice cream.
K4CHINES EQUIPPED WITH WATER COOLED CONDENSERS
-
Machines equipped with water cooled condensers must be connected
to a running water line with a pressure of at least
35 psi, and
a flow eql-lal to the estimated consumption per hour (see Water
Valve Ad justncnt)
.
Connect fitting marked "Water In" to the cold water supply,
preferably with a shut-off valve, and connect the fitting
marked 'Water Out' to
a drain.
All plumbing must meet'local and state plumbing codes.
In some
cases the
use of a high pressure flexible hose with a pressure
rating
of at least 120 psi may be used to facilitate moving the
machine for cleaning, maintenance, etc.

WATER VALVE - ADJUSTMENT
The water valve
is preset at the factory, but if an adjust-
ment should be required, proceed as follows:
To maintain a head pressure of
240-250 psig while the com-
pressor is running, attach a refrigeration high pressure
gauge to the compressor's high side discharge port, and open
the valve clockwise to increase the pressure or counter clock-
wise to decrease the pressure.
Estimated consumption is 80 gallons per hour. This figure
will increase if the vater temperature is over 68°F.
WARNING
--
Never expsse
water cooled machines to temperatures at or below
32°F without having drained the water from the condenser.
To drain, high pressure alr should be blown through the water
line from the water lnlet while the compressor is running (so
water valve is open).
his operation should be performed by
a refrigeration scrvlce man.
If this drainage
is not done properly, serious damage can
occur.
D) MACHINES WITH AIR COOLED CONDEESERS
Maintain at least
20 inches from the rear of the machine to the
wall.
The condenser should be cleaned once a month
to avoid dust and
litter from obstructing the flow of air which could affect the
performance of the machine and possibly stop its operation.
ELECTRIC= CONNECTIONS
Wiring should
be made in accordance with the National Electrical
Code and/or local electrical codes, rules
and regulations.
POWER SUPPLY must be adequate to meet requirements at all times.
Voltage fluctuations, with the machine in operation should not
exceed 2 10% of the normal or rated voltage.

F.L.A
WIRE SIZE
- - . . . - . . . .
ADEQUATE WIRING should be provided with regard to wire size or
gauge. Unless otherwise required
by the local Electrical Code,
same wire gauge at the machine junction box should be uscd for

ADEQUATE WIRING should be provided with regard to wire size
or gauge. Unless otherwise required by the local Electrical
Code, same
wire gauge at the machine junction box should be
used for the direct power line. See chart on previous page.
A separate circuit breaker with adequate fuse protection,
should be employed.
An unfused disconnect switch or proper size plug-in, close
to the freezer, is recommended.
BEATER ROTATION
After electrical connections are completed, check the rotation
of
the beater motor to see if it is in accordance with the
arrow marked on the body of the fly wheel. The rotation of
the beater should be clockwise, See Page 9b.
COLDELITE freezers are provided with protection on the beater
motor. Should the line voltage drop or if there is a short
circuit, the overload protector
will automatically disconnect
the starter and the machine
will stop immediately so that no
permanent damaqe can be caused to the motor. To start the
freezer acjain, push
the RESET button located on the front
lower portion of the control panel.
The heater or overload
must
cool down for several minutes before the RESET button
will operate.
The compressor
is also internally protected. If the Klixon
protector trips due to an overload, the compressor
will re-
activate after the Klixon automatica.lly resets.
IMPORTANT
IN
ALL INSTALLATIONS, BOTH SINGLE AND THREE PHASE, THE MACHINE
MUST BE PROPERLY GROUNDED. SINCE ALL ELECTRICAL COMPONENTS ARE
CONNECTED BY MEANS OF FLEXIBLE CONDUIT, ADEQUATE GROUND CONTI-
NUITY
IS ASSURED BY RUNNING AND FASTENING A GROUND LINE TO THE
MACHINE JUNCTION BOX.
WARNING
BEFORE REMOVING THE COVER
OF THE CONTROL BOX IN FRONT OF THE
MACHINE, TURN
THE
SELECTOR SWITCH TO OFF - POSITION AND DIS-
CONNECT MAIN SWITCH IN THE CIRCUIT BREAKER BOX.
