SECTION I – HANDLING & INSTALLATION

HANDLING & INSTALLATION 5

FREIGHT DAMAGES & SHORTAGES

The cabinet was inspected and

packaged at the factory, and should arrive in excellent condition.The transportation company or other parties involv ed in the shipment are responsible for loss and/or damage.Always make an inspection before and after uncrating. Inspect the crated unit(s) before locating (preferably at the point of unloading by the transportation company).

INSPECTING FOR DAMAGES

Always use care when removing shipping

tape, blocks, pads, hardware or other material until you are satisfied that the unit is completely operational.Contact the factory 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:

1. Have the driver note the nature and extent of the

damage on the freight bill.

2. Notify the transpor tation company at once 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 transpor ta-

tion company.

FILING A CLAIM

File a claim for loss at once with the transportation company for:

A. A cash adjustment; B.Repairs; or C. Replacement. When filing your claim, retain all packaging materials

and receipts.

HANDLING THE CABINET

The refrigeration system of the cabinet is

designed to operate with the cabinet located on a level surface. Do not tilt the cabinet more than 10° 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 30 minutes prior to starting.

CHOOSING A LOCATION

This model cabinet should be situated to allow proper air circulation. These cabinets require a 2" minimum clearance behind for proper air circulation.

The cabinet must be installed on sturdy, solid, level floor.

The cabinet must be located so it can be plugged into a properly grounded three-prong electrical outlet of 115 volt, 60 hz.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 crate base. Be sure to follow the steps in the “INSPECTING FOR DAM- AGES ”instructions.

INSTALLING THE CABINET

(Models with Top Mounted Compressor)

Whenever possible leave the crate base 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 base.

Wood runners are provided on the underside of the cabinet for ease in sliding. These runners should be left attached to the cabinet when the crate base is removed and should remain attached until after the legs are installed.The cabinet can then be pushed around more easily without scratching the floor.The runners also prevent damage to the electrical receptacle and condensate pan hardware on the cabinet bottom.

After the cabinet has been moved to the approximate final location, remove the package containing the legs from the cabinet interior. Tape the doors to prevent accidental opening when handling. Raise the sides of the cabinet high enough to mount the legs at the locations provided on the bottom of the cabinet.

IMPORTANT:

AFTER REMOVAL OF WOOD RUNNER, REPLACE BOLT “A” INTO LEG MOUNTING BRACKETS. THIS IS EXTREMELY IMPORTANT TO THE SECURE ATTACHMENT OF THE CABINET LEG. THERE MUST BE FOUR (4) BOLTS SECURING EACH LEG.

Level the cabinet by means of the leg adjustments. Cabinet doors are self-closing, and the cabinet must be level to operate properly.

6 HANDLING & INSTALLATION

CONDENSATE PAN INSTALLATION INSTRUCTIONS

MAKE SURE THE CABINET IS DISCONNECTED

FROM ITS POWER SOURCE

1. Remove and discard protective cover over electrical

receptacle on bottom of cabinet

2. Bend down front part of housing. (See above.)

3. Insert condensate evaporator pan assembly into the slide

supports on the underside of the cabinet by pushing toward back of cabinet until it stops.

4. Plug supply cord into receptacle in underside of cabinet.

5. Bend up front part of housing. Line up slot with rivnut in

cabinet bottom and insert thumbscrew through slot onto rivnut in cabinet bottom. Insert thumb screw through slot onto rivnut and tighten.

6. The assembly will now operate when power is supplied to

the cabinet.

7. Inspect rear of cabinet to ensure that the drain line from

the evaporator is properly positioned over the condensate pan.

On top mount models, allow a minimum of twelve (12) inches between the top of the cabinet and ceiling and two (2) inches from the back of the cabinet to the wall.

(Models with Bottom Mounted Compressor)

Remove the crate base mounting clips located behind the front grill.Slide the cabinet forward on the crate base to clear the rear mounting clips.

After removing the crate base, move the cabinet into location.Make sure the cabinet is lev el to ensure operation of the “self-closing” doors.

Allow a minimum of two (2) inches between the back of the cabinet and the wall for proper air circulation through the condensing unit.

CABINET STARTUP

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:

1. Cut and remove the compressor hold-down band (if applicable) so the compressor “floats” freely.

2. Check for traces of oil on the compressor pan which could mean a broken or leaking refrigeration line.

2. UNDER NO CIRCUMSTANCE SHOULD THE COM-

PRESSOR BE STARTED WHEN OIL IS PRESENT UNTIL INSPECTED BY A SERVICE TECHNICIAN.

3. INSPECT THE FACTORY WIRING FOR TERMINALS THAT MIGHT HAVE VIBRATED LOOSE IN SHIPPING. TIGHTEN ALL SCREW-TYPE TERMINALS.

4. Check the refrigeration lines to see that they are “free” and no damage was done during shipping.

5. Check fan blade(s) for “free” operation.

6. 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 10% abov e 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.

7. Make sure that the drain line has not been dislodged or broken during shipping and that the drain trap terminates properly in the condensate pan or floor drain. (See Condensate Pan on top mounted compressor.)

8. Listen for any unusual noise such as lines vibrating, etc. Correct problem by tightening screws, slightly bending tubing, etc.

9. Check proper tension on doors. (See Door Torque Adjustment.)

10. Cabinet should not be loaded with product until cabinet has operated for 24 hours and reached desirable storage temperature.

THERMOSTAT SETTINGS

The refrigerator is shipped from the factory with a thermostat setting of approximately the mid-point of the operating range. Final thermostat setting must be made in the field.

Allow the cabinet to operate until the compressor cycles on the thermostat. The normal operating temperature range for the refrigerator is:

32°F to 55°F (0°C to 13°C) NOTE:DO NOT OPERATE THE CABINET WITH THERMO-

STAT SETTINGS BELOW 32°F (0°C). The thermostat is easily adjusted with a standard screwdriv-

er. The thermostat has settings 1 through 7, tur n the thermostat to a higher number to lower the cabinet temperature.

The thermostat is located behind the evaporator front grill and can be adjusted through the grill. On some models the thermostat is located in the electrical box at the top of the cabinet.

SCIENTIFIC CONTROL AND ANNUNCIATOR PANELS

Cabinets for Scientific use may be equipped with a v ariety of optional control, alarm, and recorder devices. Each cabinet is shipped with the appropriate operators manual for the device installed on the cabinet.These operator manuals pertain to the set-up and basic operation of the control panel devices. For more comprehensive operation, repair, and maintenance information refer to the control panel service manual part number 51-0170-01.

Maintenance

and

Repair

The manufacturer requires compliance to all CGC reclamation laws by saervice companies engaging in system processing.

WARNING

To avoid the possibility of an electrical shock, turn OFF the 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 product call by first reviewing this check list of the most frequently encountered situations that are not the result of defective workmanship or materials.

COMPRESSOR RUNS TOO MUCH

1. A refrigerated cabinet automatically compensates for product 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 the 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 pressures and increase running time.Use a brush or vacuum to clean the condenser.

5. Be sure condenser fan operates.

6. Check to see that evaporator 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.

8. Check insufficient ventilation to condenser.

CABINET DOES NOT OPERATE

1. Be sure cabinet is plugged in.

2. Check that breakers or fuses are good and all switches in the supply line are ON.

3. Be sure that cabinet Master Power Supply Switch is ON.

4. If you are in an area with voltage problems, try shutting off all non-essential electrical equipment.

LIGHT IS OFF

1. If the cabinet is operating, be sure the lamp is properly seated in sockets.

2. If cabinet is not running, check that Master Power Supply Switch and Light Switch are ON, fuses are okay, no switch in the supply is OFF, and that the cabinet is plugged in.

CUSTOMER COMPLAINT ON 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 Checklist,” contact your local service company or the dealer from whom the cabinet was purchased.

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 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 doors unnecessarily.

3. Provisions for other storage of the product may be required to prevent spoilage.

If you call for service, describe your problem and giv e the following information to the service representative:

Cabinet Model No. ____________________________ Part No. ____________________________________ Serial No. __________________________________

(These numbers are located on a silver serial number rating plate in the upper left side of the cabinet interior.)

MAINTENANCE & REPAIR 39

TOOLS:

To provide full service diagnostics and repairs on these cabinets, the following tools are needed:

A Multimeter An Electronic Leak Detector An Electronic Micron Gauge A Vacuum Pump capable of pulling to 50 microns Four Hand Valves A Compound Gauge Set A cylinder of nitrogen with a regulator capable of 10 to

400 pounds. Standard refrigeration hand tools, e.g.: wrenches, tube

cutter, swage and flare tools, wire strippers, wire crimp. ers, wire cutters, slot and phillips head screwdrivers.

PRODUCT HISTORY

The first rule in servicing a refrigeration system is to determine if the problem is an electrical or mechanical failure.

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?

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

To test the 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 ha ve f ailed, allowing high pressure gas to return to the compressor.

If the compressor pulls less than 20 inches, the suction reeds have failed.

If the compressor takes longer than 40 seconds to pull 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.

ENTERING THE SYSTEM

Entering the system should only be done as a last resort. Extreme care must be used no matter what the reason for entering the system. Of course there are times when 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 hermetic compressors typically do not have valve ports, so therefore process stubs for both suction and discharge sides of the system were added.

Line taps should only be used to obtain pressure readings, and not for the reprocessing of the system. The opening of a line tap is too restrictive for the pressure of vacuum procedures.

On a hermetic compressor system, once you have determined that reprocessing a system is required, recover refrigerant and remove the line taps.

40 MAINTENANCE & REPAIR

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. Drier should be replaced prior to system processing.

Pull an evacuation to approximately 50 microns.

CHARGING

You should use a charging cylinder to measure in the correct amount of refrigerant.The charging methods are:

1. Add the refr igerant to the system until you reach a 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 at both 100% run, and a cycling temperature for at least 24 hours. 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.

MAINTENANCE & REPAIR 41

COMPRESSOR INSTALLATION & MAINTENANCE

TO CHANGE THE COMPRESSOR:

1. Disconnect the power supply to the cabinet.

2. Disconnect the power supply leads at the compressor.

3. Disconnect wires to relay and capacitors.

4. Remove relay and starting capacitor and install on new compressor.

5. Remove defective compressor from condensing unit base.

6. Set new compressor in place.

7. Reconnect relay and capacitor wires.

8. Reconnect power supply lead.

9. Leak test, evacuate, and weigh in charge.

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.

If sweat connected, clean tubing close to original drier before cutting tubing in clean area. Check that ends of the replacement drier are clean, then make brazed connection using as little heat as possible.

Cut tubing only with tube cutters, not hacksaws, to avoid metal filings from entering the system. Driers must be replaced any time you enter the system, except when you are obtaining 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 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.

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 O.K., 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 terminals 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 tight. C. The circuit is not 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 contact 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 and 4 are O.K., the relay is good. If items 3 and 4 are not as indicated, change the relay.

CAUTION:

42 MAINTENANCE & REPAIR

TO CHECK CAPACITORS

1. Disconnect the cabinet from the power supply.

2. Make sure the capacitors are discharged before touching terminal. (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, leaking, 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 show any reading, a ground is indicated. All defective capacitors should be replaced.

MAINTENANCE & REPAIR 43

OPTIONAL ALARM SYSTEM

GENERAL

This module contains audio and visual alarm signals for power failure, low and high cavity temperature, plus a contact for remote alarm connection.

1. A power failure alarm is provided to que the attendant of interrupted electrical service. This alarm is only functional when the keyed ON/OFF po wer switch is in the ON position, and the battery is connected and properly charged. In a power failure condition all cabinet monitoring and operation ceases.

1. A. A rechargeable battery is provided external to the

communicator panel, when the Alarm System Module is installed.Connect the red wire coded + to the positive battery terminal and the pink wire coded - to the negative.The battery is located in the compressor compartment.

1. B. Whenever the cabinet is plugged into an electrical

supply the power failure relay and battery charger will be energized regardless of the key ed ON/OFF power switch position. This provides continuous charging of the battery. Caution should be used when servicing the cabinet.

1. B. CAUTION - Risk of Electrical Shock Disconnect

Power Before Servicing Unit.

2. The temperature alarms indicate to the attendant that cavity conditions are in excess of either the predetermined low or high temperature limits. These cavity

temperature limit alarms are signalled from the Digital Display Module and set via the digital process meter. See Table 1 for f actory settings.T o adjust alarm points see “Setting and Revie wing Par ameters”under MODULE # 1, DIGITAL DISPLAY.

3. A button is provided for testing proper alarm system signaling. When depressed the battery is exclusively used to power all visual alarm indicators, audio alarm circuit, and relay controlling the remote alarm contact. This test should be conducted daily to insure functionability and satisfactory battery charge.When testing alarms, visually check to see if lights from “Power Failure,” “Low Temp.,” and “High Temp.” indicators come on when button is depressed. A burned out bulb in an indicator will disable that alarm function.

4. During an alarm situation, the audio portion of the alarm signal may be silenced by depressing the “SILENCE” button. If the alarm condition is not corrected within sixty minutes the audio signal will again be activated.This function has no effect on the visual signal or remote alarm contact.

5. A normally open alarm contact is provided on the reverse side of the communicator panel.It is intended for low voltage, N.E.C. Class II wiring only. Upon an alarm condition the contact closes until the problem, has been corrected.

GENERAL

Incubator cabinets incorporate a proportional electronic temperature controller.

Cavity temperature is maintained by the electronic temperature controller located on the communicator panel. Set control knob pointer on desired cavity temperature. (See photo at left.)

Cavity temperature may fluctuate slightly with varying ambient temperature.

The photo below shows the rear view of the temperature control module. This module maintains cabinet temperature by pulsing voltage to a heater located under the evaporator coil. This module consists of a solid state controller, solid state relay and a potentiometer. When replacing the solid state relay, make sure the polarity between the controller and the relay coil are the same. When the cabinet has reached set point temperature, the load light indicator on the controller should be blinking on and off.
