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 +50°C (122°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 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. 1 shows a correctly assembled pressure manometer, connected to the lubricator and a lubrication point. dd ff bb cc aa ee FIG. 1 aa bb cc dd ee ff Pressure Gauge Tee Fitting Stop Valve Lube Point Lubricator ON / OFF Switch 7. Ensure the stop valve (cc) of the pressure manometer is open. 8.

Installation and Setup Selecting Mounting Location Installation Guidelines • For all metal to metal connections (i.e., extensions, reducers, etc.) make sure to use LOCTITE® 243* (semi-tight screw locking). *Loctite® is a registered trademark of the Loctite Corporation. • Before installing the lubricator, the lubrication points and any extensions must be adequately pre-lubricated with the same lubricant contained in the lubricator. A 400 gram lubricant cartridge for grease guns is available from Graco.
Installation and Setup Remote Mounting Installations Grease Lubrication with Tube Refer to FIG. 5 - FIG. 7 for examples of correct remote mounting installations. • • Remote installations require a grease line. Graco recommends using a 5/16 inch flexible hose. A Select a position for the lubricator that is easy to access and protected from high-pressure water jets, falling materials, corrosive chemicals and extreme temperatures. B C D E F FIG.

Operation Installing Lubricator to Lubrication Point 7. Install lubricator unit into adapter (B). 1. Clean the lubrication point to remove any potential contaminants. 2. Verify the thread of the lubricator corresponds to the thread of the screw point. 3. Install reducers, extensions, grease line, etc. (if necessary). 4. Verify Dip Switches are correctly set. See Table 1, page 13. 5. Prime the grease line and all accessories with the same grease that is contained in the lubricator.
Changing the Lubrication Canister To begin the discharge: Plug power cable into lubricator (FIG. 8). . Changing the Lubrication Canister When the red and green LED light up at the same time, the lubrication canister is empty and should be replaced. NOTICE FIG. 8 During Operation: • Carry out regular performance checks. Check for possible leakages and the status of the lubricator. • Regularly monitor the fill-level of the transparent lubrication canister.
Changing the Lubrication Canister Installing New Lubrication Canister 1. If a different size lubrication canister or discharge period is going to be used, change dip switches to reflect the new canister size and/or impulse change. See Table 1, page 13. 2. Place drive unit on top of new lubrication canister until the teeth of both pieces are locked. 3. Screw the cover of the drive unit onto the lubrication canister - hand tighten only. 4. Remove plug (A) from bottom of lubrication canister. FIG. 10 9.
Troubleshooting Troubleshooting Malfunction Possible Cause Wrong cable connection Connect cable according to pin assignment (page 6). Check pin assignment. Break in cable Check voltage at plug. Attach new cable. No power supply Check power supply. Make sure there is sufficient power available for the number of lubricators used. Relay defect in machine Change relays.
