Table 9-2 in Chapter 9, shows the average flow rates for different size tubing. Normalized flow rates (mL per revolution) vary significantly, based on motor speed, tubing materials, viscosity, and mechanical tolerances in pump dimensions. Table 9-3 outlines the variances resulting from differences in motor speed, tubing materials, and mechanical tolerances. Table 9-6 outlines the variances due to differences in viscosity. To determine the chemical compatibility of a particular tubing material, it is recommended that you test the tubing under actual conditions. Tubing materials that can be used include Vinyl, Viton, Tygon, Silicone, Santoprene, and Norprene. Up to 68 durometer tubing can be used. Poor tubing life results were obtained for 5.16" (8.0mm) inner diameter Santoprene tubing. This particular tubing should not be used with the pump motor. 3.3 Tubing Life Over time and high speeds, flow rates will drop as the tubing wears out. Tubing life for various materials and sizes are shown in Table 9-4 in Chapter 9. Tubing should be periodically inspected for wear. Either move the tubing to a fresh section, or replace tubing entirely (refer to Section 3.4). 3.4 Loading the Tubing Perform ALL of the steps in Chapter 3 before turning the motor on. Follow this procedure (refer to Figures 3-8 through 3-12): Figure 3-8. Parts of the Pump Figure 3-9. Opening the Stator Figure 3-10. Loading the Tubing Clamp Screw Stator Latch Tubing Clamp Plate 3 Getting Started 3-4 NOTE CAUTION Getttiinngg SStartedd 33 Figure 3-11. Closing the Stator Figure 3-12. Adjusting the Clamp Screw 1.Refer to Figure 3-8 and Figure 3-9. Snap open the Stator by pushing the spring-loaded area of the Latch. Remove any old tubing from the pump, if necessary. 2.Refer to Figure 3-8 and Figure 3-10. Loop the Tubing over the rollers. This is easy to do even for stacked pumps. NOTE Tubing can be changed on stacked pumps without detaching either of the pumps from the motor. 3. Refer to Figure 3-11. Push the Stator closed until you hear the Latch engage. 4. Refer to Figure 3-12. Tighten the Clamp Screw until the Clamp Plate contacts the Tubing, securing it in place. 5. Set up the source and drain containers so that the tubing inlet is immersed in the fluid in the source container and the tubing outlet is in the drain container. NOTE See Section 5.2 to set the pumping direction. Getting Started 3 Notes Turning on the Power 4 4.1 Introduction to the Two Display Modes The pump motor has two modes of operation defined by whether or not the motor is running. Refer to Table 4-1. These two modes are known as the STOPPED Display Mode and the RUNNING Display Mode. Table 4-1. STOPPED vs. RUNNING Display Modes Condition Status During Status During Stopped Display Mode Running Display Mode ON/OFF Switch ON ON Motor STOPPED RUNNING Pump STOPPED RUNNING Display FLASHING NOT FLASHING Green LEDs NOT FLASHING FLASHING Fluid NOT FLOWING FLOWING 4.2 Using the ON/OFF Switch When the ON/OFF switch is pushed upwards the unit’s power is on. When the switch is pushed downward, the unit’s power is off and the top of the switch labeled “0” is visible. 4.3 The STOPPED Display Mode To enter the STOPPED Display Mode, do the following: 1. Plug in the pump motor to a convenient ac wall outlet. Use ac power within the range of 90 to 130 Vac (for 115 Vac units) or 190 to 260 Vac (for 220 Vac units). NOTE A line filter is already installed in the pump motor. 2. Attach the pump(s). Refer to Section 3.1. Turning on the Power 4 3. Turn on the unit’s power. You are now in the STOPPED Display Mode (refer to Figure 4-1). The motor and the pump(s) are stopped. The display flashes, indicating that the pump motor is waiting for you to do something. The non- flashing, green LEDs indicate the tubing inlets (refer to Section 5.2), but fluid is not flowing. STOPPED DISPLAY MODE RUNNING DISPLAY MODE START Figure 4-1. STOPPED vs. RUNNING Display Modes 4.4 The RUNNING Display Mode enters RUNNING Display Mode START STOP ACTION Pump(s) starts Display STOPPED Display Mode Figure 4-2. RUNNING Display Mode To enter the RUNNING Display Mode, do the following: 1. From the STOPPED Display Mode, press the START/STOP key. You are now in the RUNNING Display Mode. Refer to Figure 4-2. The pump motor starts. The attached pump(s) begin pumping fluid. The display is not flashing. The green LEDs flash and point to the tubing inlets. 2. Press the START/STOP key again. The pump motor stops. Fluid stops dispensing. You return to the STOPPED Display Mode. Operating the Pump Motor in the STOPPED Display Mode 5 5.1 Displaying Pump Messages in Five Different Languages English French Spanish German Italian ACTION Language Changes Display shows Language The LANGUAGE button, located toward the bottom on the back of the pump motor, changes the language of the pump messages. 1. To display pump messages in another language, press the LANGUAGE button. The language of the pump messages changes according this sequence: English, French...
