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 symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING SKIN INJECTION HAZARD High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin.
Warnings WARNING ELECTRIC SHOCK HAZARD This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock. • Turn off and disconnect power cord before servicing equipment. • Use only grounded electrical outlets. • Use only 3-wire extension cords. • Ensure ground prongs are intact on power and extension cords. • Do not expose to rain. Store indoors. EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury.
Isocyanate Conditions Isocyanate Conditions • Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates. • • Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions related to isocyanates. Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area.
Grounding Grounding Overview This single-component meter and dispense device accurately meters liquid and semi-paste materials. This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. Metering valve: attach ground wire from grounding lug to true earth ground. See Component Identification starting on page 8.
Optional Cycle Detection Sensors Optional Cycle Detection Sensors The sensors are magnetic reed switches and must be connected to an electrical control package. The sensors wires are #24 awg and have 9 foot (2.7 meters) flying leads. An LED on the sensor illuminates to indicate a change in state. h. PX-RET signal is made and Metering Rod is down (Dispense Material Complete). i. Solenoid-Open Spool Valve/EXTend is deactivated. j. Solenoid-Close Spool Valve/RETract is activated. k.

Setup Setup NOTE: See Typical Installation diagram. 3. Perform Setup procedure for feed system components. See feed system manual(s). 2. 4. Place an in-line air pressure regulator, air-water separator/filter, and shut-off/bleed valve between the air supply and the control solenoids. 5. Connect each 1/4 in. outside diameter supplied air line to the corresponding control solenoid. See Component Identification starting on page 8. 6. Connect chemical lines from feed system to metering valve material inlets.

Startup Startup 1. Lubricate the metering rod port in the oil cup retaining block and fill the spool valve ports with compatible lubricant such as mesamoll or silicone oil. Metering Rod Port Spool Valve Ports FIG. 7: Top View of Metering Valve with Top Section Removed 2. Pressurize the feed systems connected to the metering valve to prime the system. See Technical Data on page 23 for maximum inlet feed pressure. 3.
Adjusting the Shot Size Adjusting the Shot Size 1. Rotate the shot size locking ring counterclockwise to loosen. 2. Rotate the shot size adjuster to adjust shot size. 3. Rotate the shot size locking ring clockwise to tighten. 4. Dispense into waste container to test shot size. 5. Repeat until desired shot size is achieved.
Operation Operation The operation of the 1092 metering valve is controlled by an external source. If a 4104A Control Box was purchased, see the 4104A Control Box manual for operation instructions.
Pressure Relief Procedure Pressure Relief Procedure Maintenance Perform the following procedures once a shift. 1. Retract the metering rods. See the 4104A Control Box manual. NOTE: If material is leaking, see Troubleshooting on page 18. 2. Close the fluid shut-off valve. Material Reservoirs 3. Remove needle. Check material levels and refill as necessary. Ensure that the material reservoirs are properly vented. 4. Dispense 5 shots. Shots should be at least 75% of the full stroke. Air Dryer 5.

Rebuild 8. Remove the Screws, that hold the Needle Block Assembly to the Inlet Block. The Needle Block Assembly may look different than the illustration as it may have multiple needles. If the needle is a removable #10-32 or Luer Lock type consider removing it to protect it. 9. Remove and inspect the gasket. If it is in good condition you can re-use it; otherwise, discard it and secure a replacement. 23. Remove the Screws (20) that hold the Seal Plate Cups (26) to each side of the Main Body (27).
Rebuild Build the Divorced Section and Mount to the Main Body 5. Place lubricated U-cup Seal (8) lip side up into the Divorced Section (10). Place the Washer (7) over it, and reinstall the Retaining Ring (6). 6. Lubricate and insert the Metering Rod (11) into the Divorced Section (10) from the bottom and push up carefully through the U-cup seal (8). 7.
