!! IMPORTANT !!
Failuretoclosely followoperationalandmaintenance
procedures may result in damage to the unit and / or
void your warranty. Coldelite Corporation will not be
responsible for any machine not properly operated or
maintained.
Part I – Installation
Before starting this procedure, ensure that the shipping
carton does not show any evidence of damage due to
dropping or mishandling. This may indicate that the
freezer was damaged during transit or delivery.
!! IMPORTANT !!
Should the outside of the shipping carton give any
indication of possible damage, state this on the bill of
lading prior to signing. Contact the freight carrier and
request an inspection of damage. If this procedure is
not adhered to, you will forfeit your rights to file a
damage claim and be responsible for subsequent repair
costs.
A) Uncrating the Freezer
1) The outer shipping carton is secured to the shipping
pallet with strapping. When cutting this strapping, do
so with caution as it may spring out quickly. After
cutting the strapping, lift the shipping carton straight
up and off of the freezer.
2) Remove the protective foam boards and plastic
wrapping from the outside of the freezer.
3) The freezer is also secured to the shipping pallet
with strapping. Again, exercise caution when cutting
this strapping since it may spring out quickly.
4) You must now remove the side panels from the
freezer prior to lifting the freezer off of the pallet with
a lift truck. To remove the side panels, first remove the
side drip chutes and lower chute cover on both side
panels. Next remove the screws in each side panel and
gently pull down and away from the machine frame.
Remove the protective plastic coating from the outer
panelsurfaces.
B) Positioning the Machine
After removing the machine from the shipping pallet, it
is now ready to be located in its final location.
Prior to choosing a location keep in mind that the
freezershouldbeaccessibleforperiodicmaintenance
and have adequate space for necessary airflow.
Figure1
1) The freezer is equipped with adjustable legs to allow
for ease of leveling. To level the freezer, turn the lower
leg adjustment. The freezer must also be level to ensure
proper drainage from the mix tank and cylinder.
Figure2
2) If your freezer is air cooled, you MUST have
adequate spacing on both sides of the machine. You
should have a minimum of 6 inches of clearance on the
left side and 12 inches of clearance on the right side of
the machine. This will ensure an adequate airflow is
maintained.(Ref. to Figure 2)
6"12"

8
Note: If these clearances are not maintained, the
production capacity will be reduced, cycling will be
increased and the potential will exist that the machine will
stop completely
3) It is necessary to clean the air condenser each month
to remove dust, paper, etc., which may obstruct
airflow. Prior to cleaning the condenser from the
inside,disconnectthemachinespowersupply.
4) The machine should be connected to a fused
disconnect no more than six feet away. Electrical
installation MUST comply with state and / local
electricalcodes.
5) Never position the machine in direct sunlight or near
a heat source. This will reduce its performance and
possibledamagethe freezer.
6) Water connections (Water Cooled Only)are made at
the rear of the machine. A minimum of ½ inch (ID)
water supply and drain lines are recommended. Both
the water inlet and outlet lines must remain
unobstructedor themachineperformance willbe
affected.
C) Electrical Requirements
All wiring installed to operate the freezer must be in
accordance with the National Electric Code and / or
localelectricalcodes andregulations.
!! IMPORTANT !!
Thismachinemustbeproperlygrounded.Failure
toproperly groundthefreezer mayresultin
dangerous and / or fatal electric shock.
The main machine power supply must meet
requirements at all times of operation. Voltage
fluctuations must not exceed plus or minus 5% of the
ratednameplatevoltage.
AllColdelitemachinesareequippedwith stepdown
transformers for the control circuit supply. These
transformers have a “multi-tap” input which must be
wired to match the inlet voltage
(ie. 115 vac). Failure to wire to the correct supply
voltagecan result inmachine malfunction.
Electrical Connection – ( Refer to Fig. 3 )
Having removed the side panels from the frame, the
main power connection box is located on the rear, right
side bottom of the frame. The connection box is
labeled“Connect PowerLine Here”.Connectthe
power supply wires to the machines using the
appropriate electrical hardware and strain relief
devices.
Figure3
Afterthe electricalconnectionsare completed,turnthe
power supply on. At this time you must check the
beater / auger motor rotation. The correct beater
rotation ( Facing the front of the machine ) should be
counterclockwise.
D) Completing the Installation
1) All of the setup and calibration of this freezer
should be performed by an approved Coldelite Service
Technician. Failure to calibrate this freezer properly
can result in freezer damage and a voided warranty.
2) After installation and calibration of both electrical
and refrigeration circuits, the side panels should be
reinstalled.
!! IMPORTANT !!
Failuretoclosely followfactorysetupandmaintenance
procedureswill result in a voided warranty. Coldelite
Corporation will not be responsible for any freezer
which is not setup or maintained in accordance with
factoryprocedures.
NOTE: Always turn the machine OFF and
disconnect the power supply switch to the freezer
prior to exposing any electrical connections or
moving parts.
On the following pages you will find important
informationand procedureswhichdescribe theproper
sanitizing, operation, and maintenance of your
