Instructions EP-120 and EC-120 Lubricators 3A0418E EN For single point lubrication of sliding and roller bearings, chains, open gears, guideways and other system components. For professional use only. EP-120 Lubricators are used in areas that must be kept hygienically clean (e.g., food industry) and in environments which are highly contaminated, highly corrosive, or are regularly humid.
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.
WARNING WARNING PRESSURIZED EQUIPMENT HAZARD Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. Follow the Pressure Relief Procedure before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. • EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury.
WARNING WARNING PERSONAL PROTECTIVE EQUIPMENT You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to: • Protective eyewear, and hearing protection. • Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
Models: Include - lubricator canister, grease and activation screw Models: Include - lubricator canister, grease and activation screw EP-120 Lubricators Part No.
Component Identification Pressure Relief Procedure 1. Cover lubrication point and lubricator with a heavy rag to absorb any fluid that may leak out while loosening the canister. 2. Carefully unscrew lubrication canister and remove it from the lubrication point.

Installation and Setup Installation and Setup Determining Correct Mounting Method NOTE: • Direct mounting should be used for lubrication points that are easily accessible. • Remote mounting is recommended if you answer YES to any of the questions below. 1. Is the ambient temperature at the lubrication point higher than +40°C (104°F)? 2. Is it necessary to remove protective screens, walls or other types of protection in order to reach the lubrication point? 3.
Installation and Setup Graco recommends checking the counter pressure by connecting an EM-Drive Lubricator to a pressure manometer (user supplied). A pressure manometer is a simple device that measures pressure output. To build a pressure manometer you need a pressure gage (aa), tee fitting (bb) and stop valve (cc). FIG. 2 shows a correctly assembled pressure manometer, connected to the lubricator and a lubrication point. bb dd ff 3. Install lubricator unit into adapter (B). B 4.
Installation and Setup 12. If counter pressure is 4 bar (58 psi) or higher, flush lubrication point with a grease gun. EC-120 Models Only 2 After flushing, repeat counter pressure test. If the counter pressure does not decrease you may need a different lubricant or lubricator canister. Contact Graco Customer service for assistance.
Installation and Setup Priming / Prefilling Fittings and Grease Lines All grease lines (extensions and tubes) must be primed/prefilled. Without priming/prefilling, the lubricator would first need time to fill the tubes with lubricant before it would actually supply lubricant to the lubrication point. Example: A tube that is 1/2 meter long x 6 mm (19.5 inches x 1/4 inch) diameter, requires about 14 ccm (1 Tablespoon) of lubricant.

Installation and Setup Startup NOTE: The lubrication period is determined by the color of the activator screw. • Electrochemical lubricators are temperature and vibration dependent. • Refer to Table 1 to determine the correct activator screw and lubricator to use for your application and operating temperature. The data provided in this table is based on laboratory tests and under laboratory conditions and should be used as a general guideline only for selecting the discharge period.
Installation and Setup Activation D 4. When the activator is screwed in hand tight, insert a suitable tool through the top ring (D). Continue to tighten the activator until the ring breaks off at the intended breaking pint (A) (FIG. 10). DO NOT BREAK RING OFF BY HAND! A D B A C FIG. 8 A B C D Intended breaking point Seal Gas generating pellet Top ring Activate the lubricator prior to installation. For the following instructions, unless otherwise instructed, refer to FIG. 8. 1.
Changing the Lubrication Canister Canister Installation Disposal 1. Remove lubrication plug (A) (FIG. 11). Dispose of hazardous fluid in approved containers, and according to applicable guidelines. Read the MSDS to know the specific hazards of the fluids you are using. A FIG. 11 2. Tightly screw the lubricator into the lubrication point by hand - tools are not necessary (FIG. 12).
Troubleshooting Troubleshooting Malfunction Possible Cause Solution No gas development Slightly shake canister or tap on the activator screw (ring should be broken off) Still within activation period See Startup information on page 13. No lubrication Manually purge point to ensure that grease can be freely received by bearing.
Troubleshooting Malfunction Possible Cause Average ambient temperature too low for activator type Solution Select a different activator type Use a temperature independent lubricator for dispensing Manually purge point to ensure that grease can be freely received by bearing.
