CT1 BLOOD BANK REFRIGERATORSThis JEWETT Product is a complete packaged unit ready to operate when plugged into anelectrical source. It is not necessary to have a refrigeration serviceman set the unit inoperation. The unit has been tested prior to shipment. Read all the instructions beforeproceeding with installation.

INSPECTION FOR DAMAGEUncrate the product and remove all packing and crating materials. Inspect the product andparts thoroughly for damage or missing parts. File all claims for damagewith thetransportation company immediately. Do not file claims with the manufacturer.

INSTALLATION INSTRUCTIONS

1. The cabinet will pass through a standard 30" door opening.

2. Inspect the interior, exterior and mechanical equipment for special instruction tagsfastened at various points.

3. CT1 blood banks come with a removable stainless steel top so that you can choosebetween counter level (as delivered) and undercounter storage (with the topremoved). To remove the top, remove the four screws front and back, slide out thetop, discard the insulation, and replace the screws.

4. Move the refrigerator into the desired location. Make sure the bottom of therefrigerator is evenly supported. Thin shims under the points of rest can be used toequalize the distribution of weight. If the cabinet sets on an uneven floor, a slightrocking or vibration might result when the condensing unit is set in operation.

5. Make certain the refrigerator is located so the grill panel is unobstructed.

6. An automatic condensate evaporator eliminates the necessity for a floor drain. Forproper elimination of condensation, the condensate sponge should be placed into theplastic condensate tray located in the mechanical compartment.

7. The condensing unit is shipped with all service valves open and ready for operation. Donot adjust the refrigerant valves or the temperature control.

8. Use of electrical characteristics, other than those specified on the serial plate willcause permanent damage to the mechanism. The serial plate is located inside therefrigerator at the top of the right hand wall.

9. Operate the refrigerator for several hours to allow the unit to reach normal operatingtemperatures before storing product.

MAINTENANCE INSTRUCTIONS1. Frequent cleaning of the interior and exterior with water and a good fungicidal

detergent that eliminates harmful bacteria, stains and other foreign matter will keepthe unit fresh and new looking.

2. Shelves and/or drawers should be removed from the cabinet and thoroughly scrubbed.Clean door gasket periodically.

3. The unit cooler fan operates continuously when the door is closed and requires nolubrication. These models require no manual defrosting. The cooling coilautomatically defrosts when the condensing unit is on the off cycle.

4. The condensing unit needs no oil or other lubrication. The finned condenser canbecome clogged with lint or dust. The openings between the fins should be kept clean.A vacuum cleaner or small test tube brush works well for this purpose. This should beaccomplished on an annual basis. Failure to keep the condenser fins free of dirt andlint will result in erratic operation and may damage the refrigeration system.

5. Annual inspection of the mechanical refrigeration equipment by a qualified servicetechnician is recommended. A qualified mechanic can frequently make adjustmentsthat will prevent future breakdown.

6.- The refrigeration system is charged with refrigerant R134a. If the system is opened forany reason, extreme care should be taken to prevent the entry of moisture-bearing air.A new drier should be installed in the lines when the system is closed.

OPERATING INSTRUCTIONSJEWETT Blood Bank Refrigerators are factory preset to operate within a +2° C. to +4° C.temperature range.

Manual defrosting of the refrigerator cabinet is not required, as the unit cooler defrostsautomatically when the condensing unit is on the off cycle.

The unit cooler fan motor inside of the refrigerator runs continuously to provide a uniformcabinet temperature.

TEMPERATURE CONTROLThis refrigerator uses a Dixell XR60 temperature control:

3.3 CONTROL OFEThe fan control mode isselected bymeans ofthe "FnC" parameter:

Each LED function isdescribed inthe following table.

XR60C signals and records temperature alarms, together with their duration and maxvalue reached. See drawing:

Ex. High temperature alarmTemperature

An additional parameter "FSr provides the setting of temperature, detected by theevaporator probe, above which the fans are always OFF. This is used to make surecirculation ofaironly ifhistemperature islower than set in"FSr.

3.3.1 Forced activation of fansThis function managed bythe Fctparameter isdesigned toavoid short cycles offans,that could happen when the controller isswitched onorafter a defrost, when the roomairwarms the evaporator.Functioning: if the difference of temperature between the evaporator and the roomprobes ismore than the value ofthe Fct parameter, the fans areswitched on.With Fct=O the function isdisabled.

This manual ispart ofthe product and should bekept near the instrument foreasyand qUick reference.The instrument shall not be used for purposes different from those describedhereunder. Itcannot beused asasafety device.Check the application limits before proceeding.

.. Check the supply voltage iscorrect before connecting the instrument.

.. Do notexpose to water or moisture: use the controller only within the operatinglimits avoiding sudden temperature changes with high atmospheric humidity toprevent formation ofcondensation

.. Warning: disconnect allelectrical connections before any kind ofmaintenance.

.. Fittheprobe where it is not accessible bythe End User. The instrument must notbeopened.

• Incase offailure orfaulty operation send the instrument back tothe distributor orto"Dixell SJ.I." (see address) with adetailed description ofthe fault.

• Consider the maximum current which can beapplied toeach relay (see TechnicalData).

.. Ensure that the wires forprobes, loads and the power supply are separated and farenough from each other, without crossing orintertwining.Incase ofapplications inindustrial environments, the use ofmains filters (our mod.FT1) inparallel with inductive loads could beuseful.

3.2 DEFROTwo defrost modes are available through the "tdF" parameter: defrost through electricalheater (tdF =El) and hotgas defrost (tdF =in).Other parameters are used tocontrolthe interval between defrost cycles (ldF), itsmaximum length (MdF) and two defrostmodes: timed orcontrolled bythe evaporator's probe (P2P).

1.1

Incase of fault in the thermostat probe the start and stop ofthe compressor are timedthrough parameters "COn" and "COF".

3.1The regulation isperformed according tothe temperature measured bythe thermostatprobe with a positive differential from the set point: if the temperature increases andreaches set point plus differential the compressor is started and then turned offwhenthe temperature reaches the set point value again.

Temper

Model XR60C, 32x74 mm format, is a microprocessor based controller, suitable forapplications onmedium or low temperature ventilated refrigerating units. It has threerelay outputs tocontrol compressor, fan, and defrost. which can beeither electrical orreverse cycle (hot gas). It is also provided with two NTC or PTC probe inputs, one fortemperature control, the other, tobelocated onto the evaporator, tocontrol the defrosttermination temperature and to managed the fan. The instrument is fUlly configurablethrough special parameters that can be easily programmed through the keyboard.
