HANDLING & INSTALLATION-Illuminated Dipping Cabinets

FREIGHT DAMAGES AND SHORTAGES

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 transpor tation 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.

8 INTRODUCTION

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 power switch.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 220 volts with no load and it drops below 210 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 OPERATIONS

All the dipping cabinet models are of the same basic design, consisting of a bare tube condenser and a cap tube fed tank wrap evaporator.

Ice formation on the walls over a period of time is normal. This frost should be scraped off periodically in order to maintain peak performance. These cabinets are thermostatically controlled for various temperature requirements.The thermostat is located post adjacent to the unit compartment and can be accessed for adjustment by the user with a screwdriver or a dime. Thermostat position #1 being the warmest and position #7 the coldest.

These cabinets are manual defrost and a drain is provided for periodic cleaning. A garden hose can be attached to the drain plug for draining away any water that might have accumulated.This drain attachment is located in the front base rail of the cabinet.NOTE:The power supply cord must be disconnected when cleaning or servicing these cabinets.

NOTE: On initial cabinet pull down the bare tube condenser may become warm to the touch until the normal operating temperatures are achieved.

Compressors being used in these cabinets utilize refrigerant 404A and polyol ester oil. Because of the hygroscopic nature of this oil, extreme care must be taken when any component is changed within the system. In the case of compressor replacement, work should be completed before the caps are removed from the compressor.

Agitation of the oil should be kept to a minimum. Compressors should not be open to the atmosphere for more than 15 minutes max. Should contamination occur the oil can be removed and recharged (following compressor manufacturer's guidelines when performing this procedure). Because of the porous nature of plastic, polyol ester oil should be stored in a metal container. Moisture contained within the oil cannot be removed even under high vacuum conditions and must be replaced.

Refer to model serial data tag for cabinet amperage, refrigerant charge & type.

Maintenance

& Repair

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.

MAINTENANCE & REPAIR — PRE-SERVICE CHECK LIST

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 to see that condenser fans are running.

5. Be sure the condenser fan operates.

6. Check to see that condenser fans are running.

7. If product is too hard, (cold) try setting the temperature control (thermostat) warmer.This will result in warmer cabinet temperature and reduced running time.

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 start up if the power supply returns, but will require sufficient time to reach maximum cold storage performance.

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.

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 unnecessar ily.

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:

Cabinet Model ______________________________ Part Number ________________________________ Serial Number ______________________________ (These are located on a serial number rating plate

inside of the machinery compar tment of the cabinet.)

MAINTENANCE & REPAIR 29

SECTION III

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?

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 vacuum 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.

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?

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.

30 MAINTENANCE & REPAIR

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.

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:

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 flow 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.

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 day. 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.

Pull an evacuation to approximately 50 microns.You can be sure that any contaminants that can affect the system’s operation are now removed.

MAINTENANCE & REPAIR 31

COMPRESSOR INSTALLATION & MAINTENANCE / DIAGNOSTICS

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 numer ical 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 relay 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.

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.

CHANGING 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 avoid metal filings from entering the system. Driers must be replaced any time you enter the system, except when you are obtaining operating pressures.

SERVICE VALVES

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.

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.

32 MAINTENANCE & REPAIR

COMPRESSOR INSTALLATION & 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 ter minal 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.

With a good capacitor, the indicator should first move to a reading and then gradually increase to infinity.

If there is no reading change, an open circuit is indicated.

If the multimeter remains on a low resistance reading, a short circuit is indicated.

On run capacitor, touch probes to metal case and each terminal. If meter shows any reading, a ground is indicated. All defective capacitors should be replaced.

CLEANING & MAINTENANCE

CLEANING THE CABINET EXTERIOR

Wipe the exterior occasionally with a cloth dampened in mild detergent water; rinse, and wipe dry with a soft, dry cloth. Do not use abrasive or caustic

cleaners or scouring pads.

CLEANING THE CONDENSER - FIG. 1A

Periodic cleaning of the condenser can be easily accomplished by brushing the coils with a soft brush and/or using a vacuum cleaner with a brush attachment.

Be sure that dirt, dust and collection of other debris do not build up to a point air circulation through the condenser is restricted.

CLEANING THE STORAGE COMPARTMENT

1. Remove product and store it in another suitable cabinet, if possible.Be sure to prevent spoilage of the product which may occur if it is left at room temperature.

2.Turn OFF the thermostat and unplug the cabinet.

3. Remove the can skirts.

5.Wash the can skirts and the entire interior storage area with warm water and baking soda solution — about a tablespoon of baking soda per quart of water.Rinse thoroughly with clean water and wipe dry. This procedure can also be used for cleaning door gaskets.

6. A drain hose (FIG. 1B) is provided in the

compressor compartment. Connection is made to fit a standard garden hose for ease of draining water from inside of the tank area.

IMPORTANT: Do not use any objects or cleaner which may leave residues, odors, or particles. Avoid the use of strong chemicals or abrasive cleaners which may damage the interior surfaces and contaminate product within the storage area.

6.Wash, rinse, and dry the can skirts while they are

outside of the cabinet, using the same procedure as described for the storage area.

7. Be sure to correctly reinstall the can skirts, plug in

If the lid has been removed from the cabinet, wash with plenty of non-abrasive soap or detergent and water.Use the bare hand to feel and dislodge any caked soil. Rinse thoroughly with clean water. Do not use hard, rough cloths that will scratch the surface of the plastic lid. Dr y with a clean, damp chamois.

If the lid is on the cabinet where water cannot be used freely, it should first be lightly dusted (not wiped) with a soft, clean cloth.Then the surface can be wiped carefully with a wet cloth or chamois.The cloth or chamois should be kept free of grit by frequent rinsing in clean water.

Do not use solvents such as acetone, alcohol, benzene, carbon tetrachloride, fire extinguisher fluid, dry-cleaning fluid, and lacquer thinners, since they attack the plastic part of the lid. Do not use window sprays or kitchen scouring compounds.

TOUCH-UP PAINTING INSTRUCTIONS

-SPRAY PAINT

White 9 oz.Touch-up Paint: Part No.26-0899-01

1. Sand the entire bare metal or affected area and its edges until the edges are smooth or feathered.This insures that you are spraying on to a painted area that has adhesion.

2.Use an automotive primer (lacquer) ov er the bare area.

3. Scuff sand the pr imered area lightly.

4.Test spray can before using on cabinet surface. Apply in short, even strokes holding can 10" to 12" from surface, and moving rapidly during use. Apply top coat of paint in thin layers (4-5 layers minimum) with air drying time in between coats.

Starting Voltage

TYPICAL TWO-LAMP RS BALLAST

The largest percentage of light ballast used today are of the two-lamp rapid start type. In order to read starting or open circuit voltage, as it is often called, remove both lamps from their sockets.The high voltage (OVC) which starts and operated the lamp is always between the “R” and “B” sockets.The two lamps are in series between these sockets.The Y-1 and Y-2 connections provide cathode heat, and serve to connect the lamp ends together. Because the leads between Y-1 and Y-2 are connected together by jumper leads, they are always wired to sockets at one end of the fixture.Therefore, the “R” and “B” sockets are always at the other end of the fixture.This means that in order to measure the voltage which starts the lamps (OVC), the meter probes must be placed in the sockets at one end of the fixture.The Y-1 and Y-2 end of the fixture will read zero while the “R” and “B” end of the indoor ballast should read as follows:
