Models Models The six digit part number for your equipment is printed on the equipment identification label (L). Refer to the table below for information regarding the configuration of your equipment. See Pump Matrix, page 24, for a complete list of pump part numbers.
Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING 000000 000000 000000 000000 000000 000000 SKIN INJECTION HAZARD High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment. • • • • • Engage trigger lock when not dispensing. Do not point dispensing device at anyone or at any part of the body. Do not put your hand over the fluid outlet.
Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Installation Installation Wall Mount See Wall Mounting Hole Pattern, page 28. Installation of this equipment involves potentially hazardous procedures. Only trained and qualified personnel who have read and who understand the information in this manual should install this equipment. Location When selecting the location for the equipment, keep the following in mind: • There must be sufficient space on all sides of the equipment for installation, operator access, maintenance, and air circulation.
Installation Hazardous Area Cabling and Conduit Requirements Explosion Proof All electrical wiring in the hazardous area must be encased in Class I, Division I, Group D approved explosion-proof conduit. Follow all National, State, and Local electric codes. Flame Proof (ATEX) Use appropriate conduit, connectors, and cable glands rated for ATEX II 2 G. Follow all National, State, and Local electric codes. All cable glands and cables must be rated at 70°C (158°F).
Installation Typical Installation NON--HAZARDOUS AREA NON HAZARDOUS AREA Figure 1 Typical Installation Key for Fig. 1 Key for Fig. 1 A Electrical Supply (must be sealed conduit approved for use in hazardous locations) E Fluid Pressure Gauge F Fluid Shutoff Valve B Fused Safety Switch, with lock G C Start/Stop Control (must be approved for use in hazardous locations) Pump Ground Wire. Two ground terminals are provided if local code requires redundant grounding connections.
Installation Connect the Power Supply 3. Open the electrical compartment (S) on the motor. Improper wiring may cause electric shock or other serious injury if work is not performed properly. Have a qualified electrician perform any electrical work. Be sure your installation complies with all local codes and regulations. 1. Ensure that the fused safety switch (B, Fig 2) is shut off and locked out. Figure 2 Locked Out Fused Safety Switch 2. See Fig. 3.
Installation Grounding This equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current. 1. Pump: See Fig. 4. Loosen the ground screw and attach a ground wire. Tighten the ground screw securely. Connect the other end of the ground wire to a true earth ground.
Installation Fluid Line Accessories Install the following accessories as shown in Fig. 1, using adapters as necessary. All fluid lines and accessories must be rated to the maximum working pressure of 400 psi (2.8 MPa, 28.0 bar). • Fluid drain valve (H): required in your system, to relieve fluid pressure in the hose and circulation system. • Fluid pressure gauge (E): for more precise adjustment of the fluid pressure. • Fluid shutoff valve (F): shuts off fluid flow.
Operation Operation Startup To operate the pump, follow the Startup instructions for the Basic or Advanced motor in the Motor manual. The Advanced E-Flo DC motors require installation of the 24P822 Control Module Accessory Kit to provide the interface for users to enter selections and view information related to setup and operation. See the Control Module Accessory Kit manual for installation and operation information.
Maintenance Maintenance Preventive Maintenance Schedule Check Oil Level The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. See Fig. 7. Check the oil level in the sight glass (K). The oil level should be near the halfway point of the sight glass when the unit is not running.
Troubleshooting Troubleshooting NOTE: Check all possible remedies before disassembling the pump. NOTE: The LED on the motor will blink if an error is detected. See Error Code Troubleshooting in the motor manual for further information. Problem Cause Solution Pump output low on both strokes. Inadequate power supply. See Power Supply Requirements, page 7 . Exhausted fluid supply. Refill and reprime pump. Clogged fluid outlet line, valves, etc. Clear. Worn piston packing. Replace.
Repair Repair Dura--Flo Lowers Dura Disassembly 4. Insert the collars (10) into the coupling nut (11). Tighten the coupling nut (11) onto the coupling adapter (9) and torque to 90–100 ft-lb (122–135 N•m). To avoid crushing injuries or muscle strains, use caution when disconnecting the lower, it can weigh up to 25 kg (55 lbs). 2. Relieve the pressure. See the Pressure Relief Procedure, page 13. 5. Flush and test the pump before reinstalling it in the system. Connect hoses and flush the pump.
Repair Xtreme Lowers Disassembly 5. Unscrew the nuts (8) and remove the lower (7). Use a wrench to hold the tie rod flats to keep the rods from turning. To avoid crushing injuries or muscle strains, use caution when disconnecting the lower, it can weigh up to 25 kg (55 lbs). 1. Stop the pump at the bottom of its stroke. 2. Relieve the pressure. See the Pressure Relief Procedure, page 13. 3. Disconnect the hoses from the lower and plug the ends to prevent fluid contamination. 4.
Repair Reassembly NOTE: If the coupling adapter (9) and tie rods (6) have been disassembled from the motor (3), see Reassemble the Coupling Adapter and Tie Rods to the Motor, page 19 1. Orient the lower (7) to the motor (3). Position the lower (7) on the tie rods (6). Lubricate the threads of the tie rods (6). 2. Screw the tie rod locknuts (8) onto the tie rods (6). Tighten the locknuts (8) and torque to 50-60 ft-lb (68-81 N•m). 3. Raise the motor shaft.
Repair Reassemble the Coupling Adapter and Tie Rods to the Motor NOTE: Use this procedure only if the coupling adapter (9) and tie rods (6) have been disassembled from the motor (3), to ensure proper alignment of the motor shaft to the piston rod (R). 1. See Fig. 10. Screw the tie rods (6) into the motor (3) and torque to 50-60 ft-lb (68-81 N•m). 2. Screw the coupling adapter (9) into the motor shaft and torque to 90–100 ft-lb (122–135 N•m). 3. Reassemble the pump to the motor.
