FREIGHT DAMAGES AND SHOR TAGES
IMPORTANT
The cabinet was inspected and packaged at the
factory, and should have arrived in excellent
condition. The transportation company or other
parties involved in the shipment are responsible for
loss and/or “damage.” Always make an inspection
before and after uncrating, pref erab ly at the point of
unloading by the transportation company.
INSPECTING FOR DAMAGES
Note:
Always use care when removing shipping tape,
blocks, pads, hardware or other material. Contact
your dealer or distributor if technical assistance
is required.
Check the cartons or containers. If these are damaged
in any way, open them and inspect the contents in the
driver’s presence. If damage is detected, do the
following:
1. Have the driver note the nature and extent of the
damage on the freight bill.
2. Notify the transportation company’s office to request
an inspection. Carrier claim policies usually require
inspections to be made within 15 days of delivery.
3. If damage is noticed, file a claim with the
transportation company.
FILING A CLAIM
File a claim for loss at once with the transportation
company for:
A. A cash adjustment B. Repairs C. Replacement
When filing your claim, retain all packaging materials
and receipts.
HANDLING THE CABINET
Note:
The refrigeration system of the cabinet is designed
to operate with the cabinet located on a flat surface.
Do not tilt the cabinet more than 30° to any side. If
the cabinet must be tilted on an angle for handling or
moving purposes, allow it to sit in an upright position
20 to 30 minutes prior to operating.
CHOOSE A LOCATION
This model cabinet should be situated to allow proper air
circulation. The cabinet must be installed on sturdy, level
floor and positioned so that it can be plugged into a
properly grounded three-prong electrical wall outlet. The
electrical outlet should not be controlled by a wall switch
which might be turned off accidentally.
UNCRATING THE CABINET
The cabinet should be moved as close as possible to
the operating location before removing the skid. Be
sure to follow the steps in the “INSPECTING FOR
DAMAGES” instructions.
INSTALLING THE CABINET
Whenever possible leave the crate skid on the cabinet
until it is moved close to the final position. When it is
necessary to move the cabinet through a doorway, it
may be necessary to remove the crate skid.
Run the cabinet down to storage temperature before
adding product.
CAUTION
A. Do not locate cabinet where sunlight or drafts from
fans, air conditioners or open doors can affect product
temperature.
B. Run cabinet before building in or attaching panels or
accessories.
C. Employee side access panel must be kept clear for
adjustments and service.
D. Cabinet must be installed on the finished floor to
assure rear raceway cover and condensing unit
(employee side) can be pulled or removed for service.
DO NOT seal in with cover molding or caulking in the
area where condensing unit pulls out.
E. Do not use extension cords to power this equipment.
Run any necessary electrical, water supply and drain
lines before setting the cabinet in position. Shim under
the cabinet as necessary to level it. N.S.F. approval
requires sealing the cabinet to the floor. This can be
done by applying a bead of mastic sealer between the
cabinet bottom flange and the floor.
Should several cabinets be set up in a row, space is
provided in the rear toe space for routing electrical and
plumbing lines.Access to this space requires removing
screws and the metal cover which runs the length of the
cabinet.
Rivnuts are provided on the operator's side for
mounting dipperwell and other accessories.
CABINET START-UP
Once the cabinet has been located in its permanent
location and the proper power and grounding have
been provided, the following items must be checked or
completed:
A. Cut and remove the compressor hold-down band (if
applicable) so the compressor “floats” freely.
B. Check for traces of oil on the compressor pan which
could mean a broken or leaking refrigeration line.
UNDER NO CIRCUMSTANCE SHOULD THE
COMPRESSOR BE STARTED WHEN OIL IS
PRESENT UNTIL INSPECTED BY A SERVICE
TECHNICIAN.
C. INSPECT THE FACTORY WIRING FOR TERMINALS
THAT MIGHT HAVE VIBRATED LOOSE IN
SHIPPING. TIGHTEN ALL SCREW TYPE
TERMINALS.
D. Check the refrigeration lines to see that they are
“free” and no damage was done during shipping.
E. Check fan blade for free operation.
F. Turn on the main po wer s witch.Once the compressor
starts, the voltage should be checked at the
compressor terminals to determine if there is proper
voltage to the compressor. The voltage should not
exceed the 10% above or below the rated
compressor voltage.
EXAMPLE: If the voltage reads 115 volts with no load
and it drops below 103 volts when the compressor
starts, it may indicate that the supply wiring is too small
or that the wire run is too long.
G. Listen for any unusual noise such as lines vibrating,
etc. Correct the problem by tightening screws,
slightly bending tubing, etc.
H.The temperature control thermostat which is located
in the rear post is factory set for average conditions.
A customer adjustment requires a coin or
screwdriver to turn the slotted shaft.A numbered dial
makes it easy to keep track of adjustments. #1 is
warmest setting and #7 is coldest setting. An “OFF”
position is provided for your convenience in
defrosting the cabinet.
I. Allow the cabinet to pull down and cycle prior to
loading with product (Approx. 24 hours).
GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong
(grounding) plug for your protection against shock
hazards.The appliance should be plugged directly into
a properly grounded three-prong receptacle.
Where a two-prong wall receptacle is encountered, it
must be replaced with a properly grounded three-prong
receptacle in accordance with the National Electrical
Code and local codes and ordinances. The work must
be done by a licensed electrician.
IMPORTANT
Do not, under any circumstance, cut or remove the
round grounding plug from the appliance plug.
WARNING
Consult a licensed electrician if you have any doubt
about the grounding of your wall receptacle. Only a
licensed electrician can determine the polarization of
your wall receptacle. Only a properly installed threepronged wall receptacle assures the proper
polarization with the appliance plug.
IMPORTANT USAGE INSTRUCTIONS
Dipping Cabinet
The cabinet must be located in an area free from air
drafts created by open doors, air conditioning ducts,
and fans. The cabinet should not be located in the
direct sunlight.
The rear grill must be clear of any obstructions so the
intake and exhausting of air f or the condensing unit can
move freely.
Dipping cabinets are designed for use in an air
conditioned store. This cabinet is designed for
merchandising, not hardening of the product.
High humidity can cause fogging of the lid and front glass.
High temperatures, installation of warm product and
heavy usage can cause the product to soften. This
condition will be more noticeable at the top of the cans.
The corners of the cabinets are the coldest areas.
These areas should be used for product that is more
difficult to keep firm.
Frost and ice act as insulators.The need for defrosting
will depend on usage and product firmness.
If the frost is scraped daily with a plastic scraper,
intervals between complete defrosting may be
extended.
Thermostat adjustments should be made one
increment warmer or colder allowing 24 hours between
adjustments to allow the product to stabilize.

GENERAL INFORMATION - REFRIGERATION SYSTEMS
PRINCIPLES OF OPERATION 11
FIGURE 1
Basic refrigeration is based upon the Second Law of
Thermodynamics … “Heat will always flow from a warm
object to and be absorbed by an object of substance of
colder temperature.”
The purpose of a mechanical refrigeration system is to
provide for efficient and continuous cooling.
In order for this to take place, the system must provide
a means to transfer heat from the products being
refrigerated to an area that will not affect the product
(See Figure 1).
This is accomplished through the circulation of
refrigerant contained in conductive tubing, past the area
where the products are stored.
The refrigerant absorbs the heat from the product area
and transports it to where the heat can be dissipated
into the air outside the cabinet. Four essential
components are needed in a simple refrigeration
system:
An Evaporator
A Compressor
A Condenser
and a Refrigerant Flow Metering Device
The purpose of the evaporator is to draw the heat from
the product or storage area. As low temperature, low
pressure liquid refrigerant enters the evaporator, it
begins to boil or vaporize as it absorbs the heat of the
product and cabinet interior.
The vaporized refrigerant is drawn through the
evaporator by the compressor , in addition to causing the
necessary flow of refrigerant within the circuit.
The compressor also increases the pressure of the
vaporized refrigerant flowing from the compressor to the
condenser.
The increased pressure causes the temperature of the
refrigerant to rise above the ambient temperature of the
room.
This condition allows the heat in this vaporized high
pressure refrigerant to be released into the room’s
ambient environment.
As heat is released, the vaporized refrigerant returns to
a liquid state.
If there is a large amount of heat to be released, this
heat transfer is increased by using a fan to ensure a
constant flow of cooler ambient air through the
condenser coil.
The cooled liquid refrigerant leaves the condenser
under high pressure and travels to the refrigerant flow
metering device.
This device regulates the flow of refrigerant into the
evaporator.
By restricting this flow, the liquid refrigerant mo ves to the
evaporator under low pressure.(See FIGURE 1)
This lower pressure is necessary for the refrigerant to
have the capability to vaporize and absorb heat.
The cycle will continue until the desired temperature
within the product area is reached.
At this point, the compressor shuts off and the
refrigerant cycle is interrupted until further cooling is
required.
This simple refrigeration system is known as a single
stage system. It is the most common refrigeration
system and is used for applications where the product
area temperatures do not exceed -20° Fahrenheit.
The single stage system is used on product dipping
cabinets.
Product dipping cabinets utilize a cold wall evaporator.
(See FIGURE 2).
Here the refrigerant lines actually contact the product
area’s inner wall. Heat is transferred through the wall
and into the refrigerant.
To understand how the refrigerant system creates cold
temperatures, it is important to understand how the
temperatures of the area into which the heat will be
dissipated affect the system’s performance.
Simply stated, a refrigerant system’s ability to cool a
product area is dependent upon the unit’s ambient
environment.
For example, a single stage system dissipating heat
throught its condenser into a 60°F ambient environment
is capable of cooling a cabinet’s interior to a lower
temperatue than an identical system operaing in an
80°F ambient environment.
To understand the complete heat transfer and extraction
process in systems, let’s discuss the function of the
major system components.
There are three components in each system used for
transferring heat. They are the Evaporator, the
Compressor, and the Condenser.
Heat is transferred through the refrigerant lines by the
compressor. This heated refrigerant arrives at the
condenser for dissipation.
The heat transfers to the e vapor ator because it is colder .
The heat then moves through the compressor and
leaves the cabinet at the condenser, where it transfers
or dissipates into the cooler room air.
This heat transfer continues until the system has
absorbed all the heat it is capable of removing, and has
pulled down to the coldest temperature possible, or it
has reached its thermostatic set point and shuts off.
On product dipping cabinets, the copper evaporator
lines are strapped to the inner tank walls to form a cold
wall evaporator.
This is foamed into place with two inches of urethane
instulation to form a rigid bond between the outer shell
and inner liner, which is another metal barrier used for
strength and insulation separation.
The direction of the refrigerant flow is from the top to the
bottom.
The cold wall evaporator is not serviceable within the
walls of the cabinet because of the foam construction.

WARNING:
To avoid the possibility of an electrical shock,
turn OFF thermostat and unplug the power cord
of the cabinet before cleaning or touching
electrical connections or parts.
PRE-SERVICE CHECK LIST
MAINTENANCE & REPAIR 21
You may avoid the cost and inconvenience of an
unnecessary service call by first reviewing this check
list of the most frequently encountered situations that
are not the result of system component failure.
COMPRESSOR RUNS TOO MUCH
1. A refrigerated cabinet automatically compensates for
service loading by running longer and more often.
Before calling for service, check running time for at
least one hour the first thing in the morning (before
store traffic starts).
2. Be sure doors seal. A faulty gasket seal will cause
increased running time.
3. Check the room temperature.The warmer the room,
the more the compressor will run.
4. Check the condenser to be sure the face is clean.
Dirt and lint will raise the pressures and increase
running time. Use a brush or vacuum to clean the
condenser.
5. Check to see that condenser fans are running.
6. If product is too hard, (cold) try setting the
temperature control (thermostat) warmer. This will
result in warmer cabinet temperature and reduced
running time.
CABINET DOES NOT OPERATE
1. Be sure the cabinet is plugged in.
2. Check that the breakers or fuses are good and all
switches in the supply line are ON.
3. Be sure that cabinet Master Supply Switch is ON.
4. If you are in an area with voltage problems, try
shutting off all non-essential electric equipment.
LIGHT IS OFF
1. If the cabinet is operating, be sure the lamp is
properly seated in sockets.
2. If the cabinet is not running, check that Master Supply
Switch of cabinet is ON, fuses are okay, no switch in
the supply is off and the cabinet is plugged in.
CUSTOMER COMPLAINT
OR STORED PRODUCT
1. Check cleaning solutions used inside cabinet.
2. Check cleaning solutions, paint or other contaminants used in store maintenance.
3. Sometimes the ingredients used in some products or
containers will contaminate other products.
4. Be sure to follow a weekly schedule for cleaning
cabinet interior.
SERVICE
In the event of a malfunction, damage to the cabinet, or
if the cabinet requires service beyond the items in the
“Pre-Service Check List,” contact your local
refrigeration service company or the dealer or
distributor you purchased the unit from.
POWER FAILURE
Do not open the cabinet doors unnecessarily if power is
cut off due to electrical failure.The cabinet will star t up
if the power supply returns, but will require sufficient
time to reach maximum cold storage performance.
CABINET FAILURE
1. If the cabinet has stopped operating, check that the
cabinet is securely plugged in and turned on.Contact
a licensed electrician to locate and correct any power
supply problems.
2. Do not open the cabinet lids unnecessarily.
3. Provisions for other storage of the product may be
required to prevent spoilage.
If you call us for service, describe the problem and give
the information from the following list to the service
representative:

inside of the machinery compar tment of the cabinet.)
SECTION III
MAINTENANCE & REPAIR
22 MAINTENANCE & REPAIR
TOOLS:
To provide full service diagnostics and repairs on these
cabinets the following tools are needed:
A V olt Meter
An Amp Meter
An Ohm Meter or tiplet meter to handle all three functions
An Electronic Leak Detector
An Electronic Micron Gauge
A Vacuum Pump capable of pulling to 50 microns
Four Hand Valves
A Refrigerant Reclaimer
A Compound Gauge Set
A cylinder of nitrogen with a regulator capable of 10 to
400 pounds.
Standard refrigeration hand tools like:wrenches, tubing
cutter, swage and flare tools, wire strippers, wire
crimpers, wire cutters, standard and phillips head
screwdrivers.
PRODUCT HISTORY
The first rule in accurately servicing a refrigeration
system is to determine if the problem is an electrical or
mechanical failure within the refrigeration system.
First, try to obtain the product’s history of operation
from the customer.This will help identify the source of
the problem.
Good facts from the cabinet user can help identify
whether the problem is electrical, within the
refrigeration system, or a “misapplication by the user.”
Get the history of operation and failure by asking these
questions:
1) Were there any brown-outs or power outages that
they are aware of?
2) Is the cabinet on a dedicated circuit?
3) Has any other equipment in this area had
operational problems?
4) When was the last time the cabinet’s operation was
confirmed as working properly?
5) When was a problem noticed?
6) How long has the equipment run without this
problem? (Years? Weeks? Days? Hours?)
7) Was anything tried prior to your arrival?
8) Was the warm-up fast, as in three to six hours, or
over a prolonged time, as in three to five days?
9) If the cabinet was running for a long time, was the
temperature recovery after entering the cabinet
always within an hour, or did it appear as though
recovery time was longer as usage went on?
The refrigeration system should only be entered if it is
absolutely necessary. It is critical that a clean,
uncontaminated system be maintained.
If a system is unable to reach the proper operating
temperature, a test of the unit’s mechanical
refrigeration components is required.
COMPRESSOR EFFICIENCY TEST
If the cabinet has a semi-hermetic compressor, begin
by testing the compressor’s efficiency.
To test a semi-hermetic compressor, place compound
gauge on the compressor’s suction port.
While the compressor is running, close off the suction
line so that only the port and valve are part of the
compressor’s low side.
When the valve is closed and v acuum has started, time
how long it takes to pull the compressor’s low side to its
lowest possible vacuum.
Compressors used on these cabinets should be
capable of pulling at least 20 to 22 inches of vacuum in
less than 40 seconds.
Next, shut off the compressor and watch the gauge. A
one or two inch rise in pressure is acceptable, since a
small amount of freon may remain on the low side of the
compressor, after which the reading should stabilize.
If the pressure continues to rise, the discharge reeds in
the valve head are bad, allowing high pressure gas to
return to the compressor.
If the compressor pulls less than 20 inches, the suction
reeds are bad in the valve head.
If it takes longer than 40 seconds to pull the
compressor, to its ultimate low vacuum, one or both
cylinders are not functioning as they should. Any
reading less than these will require replacement of the
compressor.
MAINTENANCE & REPAIR 23
ENTERING THE SYSTEM
Entering the system should only be done as a last
resort. Extreme care must be used no matter what the
reason is for entering the system. Of course there are
times it cannot be avoided, such as component or
compressor replacement, or a leak within the system.
The system must also be entered any time you need to
obtain the operating pressures. Again, use extreme
caution to avoid any possible contamination.
Cabinets that use semi-hermetic compressors allow
easy access through the valve ports.
Cabinets using hermetic compressors do not have
valve ports, this product has process stubs for both
suction and discharge sides of the system.
Line taps should only be used to obtain pressure
readings, and not for reprocessing a system. The
opening of a line tap is too restrictive for pressure of
vacuum procedures.
Install hand valves at the process stub ends. Hand
valves will be less restrictive to flo w because of a larger
opening. They will also be easier to use during repair
procedures.
EVACUATION
Once the system has been cleaned and components
have been replaced, you are ready to initiate the final
servicing procedures necessary to achieve proper
cabinet operation.
Pull an evacuation to approximately 50 microns. You
can be sure that any contaminants that can affect the
system’s operation are now removed.
Use this time to check any joints for potential leaks.
CHARGING
You should use a charging cylinder to measure in the
the correct amount of refrigerant. The charging
methods are:
1) Add the refrigerant to the system until you reach a
predetermined balanced pressure.This will give you
an approximate static charge.
2) Weigh in the refrigerant using a scale calibrated in
ounces.
The cabinet’s operation is now ready to be tested. A
final check of the refrigeration lines should be made
before running the cabinet.
Be sure the refrigeration lines are not kinked or rubbing
against each other.
Also check that the door seals properly. An air leak will
affect proper operation, and the cabinet’s ability to
reach its coldest temperature.
Run the cabinet a both 100% run and also at a cycling
temperature for at least one da y. If the temperature and
pressures are correct, the system can be considered
repaired.
Hermetic systems should now have their process stubs
pinched off, hand valves removed and the ends brazed
shut.
COMPRESSOR INSTALLA TION & MAINTENANCE / DIAGNOSTICS
24 MAINTENANCE & REPAIR
HOLD DOWN BOLTS
All models with Copeland compressors have hold down
bolts. The compressor has a metal hold down band
strapping it tightly to the cabinet body. This band should
be removed and discarded upon installation. If
compressor does not float freely, keep backing off all of
the retaining nuts until it does.
CHECKING COMPRESSOR THAT WON’T
START ON CORD CONNECTED CABINETS
1. Check that the supply plug is in wall outlet and that
outlet has the proper voltage.
2. Check that the cabinet thermostat is on a numerical
setting.
If items 1 & 2 are OK:
3. Pull condensing unit out of the cabinet and remove
compressor terminal cover. Check proper voltage at
terminals.
TO CHANGE THE COMPRESSOR:
1. Disconnect the power supply to the cabinet.
2. Disconnect power supply leads at the compressor.
3. Disconnect the wires to the relay and capacitors.
4. Remove the rela y and starting capacitor and install on
the new compressor.
5. Remove the defective compressor from the
condensing unit base.
6. Set the new compressor in place.
7. Reconnect the relay and capacitor wires.
8. Reconnect the power supply lead.
9. Leak test, evacuate, and weigh in charge.
TO CHANGE THE DRIER
If flare connected, make sure flares and faces of
fittings on new drier are clean and in good condition
before installing new drier.
Cut tubing only with tube cutters, not hacksaw’ s , to av oid
metal filings from entering the system. Driers must be
replaced any time you enter the system, except when
you are obtaining operating pressures.
SERVICE V ALVES
The compressors on some cabinets have service valves
for measuring suction and discharge pressures. Two
types are used.The first type is connected directly to the
compressor body or shell and back seats to connect
gauges to the access port. The second (Schrader type)
is on the end of a process tube and requires a gauge or
charging line with a depressing pin to open valve when
the connection is made.
CAUTION
This type valve should be tightly capped except
when making the gauge connection.
TO CHECK FOR OPEN WINDINGS
Use a multimeter. Measure ohms between “C” and “R”
and between “C” and “S”.
If windings are OK, multimeter will show a resistance
reading between terminals.
If there is no reading, the compressor, winding or
windings are open and the compressor should be
replaced.
TO CHECK FOR GROUNDED COMPRESSOR
Use multimeter.Touch probe from each terminal to an
unpainted surface of compressor body. If there is no
ground, there will be no change of the meter.
WARNING: Be Careful Not to Touch
Uninsulated Parts of the Meter Probes.
A reading indicates a ground and the compressor
should be replaced.
If there is voltage at the compressor terminals and the
compressor tries, but does not run, check voltage at the
compressor terminals while attempting to start the
compressor.If the voltage at the compressor terminal is
below 90% of the nameplate voltage, it is possible the
motor may not have developed sufficient torque to start.
Check to determine if:
A.Wire sizes are adequate.
B. Electrical connections are loose.
C. The circuit is overloaded.
D. The power supply is adequate.
A defective relay or capacitor may prevent the
compressor starting.
TO CHECK OUT THE RELAY
1. Disconnect the cabinet from the power supply.
2. Remove the wires from the relay.
3. Touch probes to the terminals. Meter should show
infinity if closed.
4.Touch probes to the terminals of coil. The meter
should show a resistance reading.
If items 3 & 4 are OK, the relay is good. If items 3 & 4
are not as indicated, change the relay.

COMPRESSOR INSTALLA TION & MAINTENANCE / DIAGNOSTICS
TO CHECK CAPACITORS
1. Disconnect the cabinet from the power supply.
2. Make sure the capacitors are discharged before
checking. (Shunt across the terminal of capacitor
with a heavy insulated wire.)
3. Remove the wires from the capacitors.
4. Any capacitor found to be bulging, leading, or
damaged should be replaced.
5. Use a multimeter to check the run and start
capacitors for shorts or open circuits.
A. Set ohmmeter to X1000 scale.
B. Standardize equipment
C. Touch probes to capacitor terminals.
1. With a good capacitor, the indicator should
first move to zero and then gradually increase
to infinity.
2. If there is no movement of the ohmmeter, an
open circuit is indicated.
3. If the ohmmeter indicator moves to zero, and
remains there or on a low resistance reading,
a short circuit is indicated.
