Warranty Statement

Scientific Systems, Inc. (SSI) warrants that instruments or equipment manufactured by it for a period thirty-six (36) months from date of shipment to customer, against defects in materials and workmanship under normal installation, use and maintenance. Expendable items and physical damage caused by improper handling or damage caused by spillage or exposure to any corrosive environment are excluded from this warranty. The warranty shall be void for Polyetheretherketone (PEEK) components exposed to concentrated Nitric or Sulfuric acids which attack PEEK, or methylene chloride, DMSO or THF which adversely affect UHMWPE seals and PEEK tubing. Any defects covered by this warranty shall be corrected by replacing or repairing, at SSI’s option, parts determined by SSI to be defective.

Spare or replacement parts and accessories shall be warranted for a period of 12 months from date of installation at customer against defects in materials and workmanship under normal installation, use and maintenance. Defective Product will be accepted for return only if customer returns them to SSI within thirty (30) days from the time of discovery of the alleged defect, and prior to return, obtains a Return Goods Authorization (RGA) number from SSI, and provides SSI with the serial number of each instrument to be returned. Freight costs for the return of defective Product is the responsibility of SSI. SSI shall specify the freight carrier for returns.

The warranty shall not apply to any Product that has been repaired or altered except by SSI or those specifically authorized by SSI, to the extent that such repair or alteration caused the failure, or to Product that has been subjected to misuse, negligence, accident, excessive wear, or other causes not arising out of a defect in material or workmanship.

The warranty shall not apply to wear items, specifically:

Check Valves

Piston and Wash Seals

Pistons

Pulse-Damper Diaphragms

Inlet Lines

Filter Elements

The following is the exclusive procedure by which to make claims under this warranty. Customer shall obtain SSI’s oral or written authorization to return the product and receive a Return Goods Authorization (RGA) number. The Product must be returned with the RGA number plainly visible on the outside of the shipping container to SSI. It must be securely packed in a rigid container with ample cushioning material, preferably the original packaging. All claimed defects must be specified in writing, including the RGA number, with the written claim accompanying the Product. Product shall be shipped to SSI at customer’s expense. SSI shall bear the expense of return shipment.

If it appears to SSI that any Product has been subjected to misuse, negligence, accident or excessive wear, or is beyond the warranty period, customer shall be notified promptly. SSI shall notify customer of its finding and provide an estimate to repair such Product at the then current rates for parts and service. SSI shall either repair the product per customer’s authorization or shall return such Product not repaired to customer at customer’s expense. SSI may invoice customer for the freight costs of any Product shipped back to customer by SSI which is not covered under the warranty.

Limitations of Warranty. THE FOREGOING WARRANTIES AND LIMITATIONS ARE CUSTOMER’S EXCLUSIVE REMEDIES AND ARE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR

In particular, as stated above if pumping Buffers, Acids/Bases or any inorganic solution near saturation, the pump should utilize the Self Flush feature. With every piston stroke, an extremely thin film of solution is pulled back past the seal. If this zone is dry without use of Self Flush, then crystals will form with continuous operation, which will ultimately damage the seal 1.1.4 Self-Flushand Seal LifeFlow Rates 2.3Fluid Connections & Priming 2.INSTALLATION2.1Unpacking and Inspection 2.2Location/Environmentopaque to the flush housing as shown SELF-FLUSHPUMP Connect wash solution inlet and outlet tubing2.5Solvent Preparation 2.5.1 Solvent Out-gassingand Sparging2.4Electrical Connection 2.5.4 Initial system pressurization Daily 2.6.1Mobile Phase Reservoirs2.5.2 Cavitation 2.5.3 Filtration2.6.6 Long Term Pressure Calibration Accuracy 2.6.2 Self-FlushSolution2.6.3 Inlet Tubing and Filters 2.6.4 Priming the Pump and the Flushing Lines2.7Preparation for Storage or Shipping 2.7.1Isopropanol Flush2.7.2 Packaging for Shipping 3.1.1Control Panel 3.OPERATIONNon-volatileMemory Reset If the pump is operating erratically, there is the possibility that the memory has been corrupted. To reset the memory and restore the pump to its default parameters, press and hold the UP-ARROWbutton when the power is switched on. Release the button when the display reads rES. The parameters stored in non-volatilememory, i.e., the flowrate, the pressure compensation, the voltage/frequency select, the lower pressure limit, and the upper pressure limit will be set to the factory default values. The head type setting is the only parameter not changed by the non-volatilememory reset function. If the firmware is upgraded to a newer version, a non- volatile memory reset will automatically occur the first time the power is switched on 3.5Rear Panel Remote Input 3.6Symbols4.1.3 Pulse Damping 4.THEORY OF OPERATION4.1.1Liquid System Flow Path 4.1.2 Pump Cycle4.2.4 Motor Stall Detector 4.2.2 DC Power Supply4.2.1 Microprocessor Control 4.2.3 Remote InterfacingPage 5.1Filter Replacement 5.MAINTENANCE5.1.1 Inlet Filters 5.2.1Removing a Pump Head3.Remove the inlet line from the inlet check valve OUTLET FLUSHING CHECK VALVE OUTLET FLUSHING 1.Inspect the piston seal cavity in the pump head. Remove any foreign material using a cotton swab, or equivalent, and avoid scratching the sealing surfaces. Repeat for the self-flushhousing. Be sure no fibers from the cleaning swab remain in the components 5.2.2 Cleaning the Pump Head Assembly3.If the check valves have been removed, tighten the check valves on stainless steel pumps to 75 inch-poundsor enough to seal at maximum pressure. Do not exceed maximum torque. For Bioclean PEEK pumps, tighten each check valve firmly by hand. Do not go ¼ turn past finger tight Lower than normal pressure, pressure variations, and leaks in the pumping system can all indicate possible problems with the piston seal. Depending on the fluid or mobile phase used, piston seal replacement is often necessary after 1000 hours of running time 5.2.3 Replacing Piston Seals1.Remove the pump head as described in Section 5.2.1.

Any device capable of providing the proper run/stop logic level, flowrate control frequency, or flowrate control voltage can be used as a remote controlling device for pump operation via this connection. The terminal board connectors can be removed for ease of connecting wires, if desired, by pulling firmly rearward and should be reinserted firmly afterward A.2.1 Pressure Fault and Motor Stall Fault Outputthe EVENT 1 terminal and the EVENT 2 and EVENT 3 terminals is affected. EVENT 2 is Normally Closed connected to EVENT 1 until a fault occurs and then opens. EVENT 3 is Normally Open not connected to EVENT 1 until a fault occurs and then closes A.2.2 General Information on InputsThe PUMP-RUN, PUMP-STOP,and ENABLE IN inputs operate from an internal 5 VDC source and each one draws approximately 0.008 amps when connected to COM. To activate either the PUMP- RUN, PUMP-STOP,or ENABLE IN input connect it to COM. Any device capable of switching 0.008 amps can be connected between the PUMP-RUN, PUMP-STOP,or ENABLE IN input and COM, such as: a switch contact, a relay contact, an open collector output, an open drain output, or any output with a high logic level output of 3.8 to 6.0 volts and a low logic level output of 0.0 to 0.5 volts. A switch contact or a relay contact is preferred since this type of connection will provide isolation between the pump and the controlling device. The COM terminal is internally connected to the pumps chassis ground and should be connected to the controlling devices ground or zero volt terminal when the controlling device has an open collector output, an open drain output, or any output with logic level output A.2.4 Run and Stop InputsWhen activated ENABLE IN is at a low logic level, the ENABLE IN input disables flowrate control on the front panel and enables flowrate control on the back panel A.2.4 Enable InputEZ GRIP FITTING GUIDE APPENDIX BScientific Systems Inc Warranty Statement A-10
