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 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. Cycle Detection Spool Sensors The spool sensors are magnetic reed switches and must be connected to an electrical control. An LED on the switch illuminates to indicate the shifting of the spool. Metering valve: attach ground wire from grounding lug to true earth ground.

Setup Setup NOTE: See Typical Installation diagram. 1. Perform Setup procedure for feed system components. See feed system manual(s). 2. 2. Place an in-line air pressure regulator, air-water separator/filter, and shut-off/bleed valve between the air supply and the control solenoids. 3. Connect each 1/4 in. outside diameter supplied air line to the corresponding control solenoid. See Component Identification starting on page 7. 4. Connect chemical lines from feed system to metering valve material inlets.
Setup Valve Mounting Diagram As desired, use the following diagram to mount the metering valve. NOTE: Valve shown is for controls/motor integrated. For valve without controls/motor integrated, mounting pattern is the same just less LS-Home, solenoid open/close and all the wires terminated at a plug.

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 (oil cup) Spool Valve Ports (wet cups) 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 25 for maximum inlet feed pressure. 3.
Operation Operation The operation of the 1053 metering valve is controlled by an external source. If a Control Box was purchased, see the Control Box manual for operation instructions. See Related Manuals on page 2.
Pressure Relief Procedure Pressure Relief Procedure Maintenance Perform the following procedures once a shift. 1. Retract the metering rods. See the Control Box manual. See Related Manuals on page 2. NOTE: If material is leaking, see Troubleshooting on page 17. 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.
Troubleshooting Troubleshooting Perform Pressure Relief Procedure before performing any troubleshooting procedure.
Rebuild Rebuild Before proceeding, remove material feed line and pump material out of the valve. Shut power off from control panel and disconnect main power. Disconnect the motor wire harness from the system. Loosen the home and spool sensor set screws. Note the position of the sensors and slide them out of the valve. Disconnect the air lines. Disassembly Refer to the illustration below and the drawings in the back of this manual for your exact model. Disassembly Of 1053 Valve Section 1.

Rebuild Assembly Before proceeding, remove any old o-rings or seals from the valve and discard, clean the valve parts with an appropriate solvent and replace o-rings and seals with new parts from seal kit. Use Krytox 203GPL (part number 84/0200-K3/11) for lubricating valve parts including seals and o-rings. Assembly Of 1053 Valve Section Note: Check the Metering Rod (1), Dispense Sleeve (27), and Spool Assembly (7) for wear and if they are worn secure replacements before proceeding.
Rebuild 20. Lubricate the bore in the End Cap (25). Slide the Spool Shift Piston (24) into the left End Cap (25) tucking the lip of the U-cup seal (24) into the End Cap (25) carefully. 21. Install the Piston/End Cap onto the left Seal Plate (14) using four Screws (26). Tighten the screws in a cross pattern gradually to prevent binding due to misalignment (like you would tighten lug nuts on a car tire). 22. Push the Spool Rod (7) into the left side until it contacts the piston.
Rebuild Motor and Motor Coupling Assembly Disconnect electrical power before servicing the motor and motor coupling assembly. Refer to the illustrations on the following page. 1. Assemble Motor Coupler (3) by inserting Roll Pins (5) and Screws (4). Note: This step is only required if the motor coupler has been disassembled for service or removed from the motor. 2. Assemble Lead Screw Nut (6) with Bearing (9) and E-ring (8). 3.
