WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames, or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D Be sure the entire fluid system is properly grounded. Refer to your pump instruction manual for complete details. See Grounding on page 6. D If there is any static sparking or you feel an electric shock while using this equipment, stop dispensing immediately. Do not use the equipment until you identify and correct the problem.
Installation Typical Installations Fig. 1 shows a typical hose reel installation. These dispense valves can also be installed on a console, as shown in Fig. 2. The typical installation shown in Fig. 1 is only a guide. The components shown are typical; however, it is not a complete system design. Contact your Graco distributor for assistance in designing a system to suit your particular needs. CAUTION CAUTION This dispense valve is not designed for in-line installation.
Installation WARNING PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved.
Installation 10. Thread the sealing nut (5c, 6c, or 7c) onto the extension (5a) or street elbow (6d or 7d), thread the extension or elbow in at least three full turns, position it for proper alignment, and tighten the sealing nut. The PTFE seal on the sealing nut must face the valve housing. See Fig. 4. Model shown has 75_ bend rigid extension hose NOTE: The flexible extension (6a) can also be threaded directly into the meter outlet without the street elbow or sealing nut.
Setup Terms The following terms are shown on the display and/or used often in this instruction manual. D R--TOTAL: resettable total Displayed to show the cumulative amount that the dispense valve has dispensed in all modes. It can be reset to zero. D TOTAL: non-resettable total Displayed to show the cumulative amount that the dispense valve has dispensed in all modes for the history of the unit. It cannot be reset.
Setup Selecting Dispensing Options This is the procedure for setting or changing the resettable total, units of measurement, calibration factor, auto preset amount, and shut-off default amount: 1. If the display is asleep, wake it up by pressing the Manual/Reset or Auto/Reset button. 2. To enter the dispensing options menus from any mode, press and hold the Manual/Reset and Auto/Reset buttons simultaneously for four seconds.
Setup Calibration Factor Auto Preset Amount In this menu, you can recalibrate the meter for different fluids. In this menu, you can specify an amount to be displayed when you enter the Auto dispense mode. Typically, you would enter the amount you most frequently dispense. 1. If you have not already entered the dispensing options menus, do steps 1 and 2 in Selecting Dispensing Options on page 8. 2.
Setup Shut-Off Default Amount The shut-off default amount is for preventing accidental overfills when dispensing with the trigger locked in Manual mode. The shut-off default amount is factory preset at 5 quarts. In this menu, you can change the shut-off default amount. 1. If you have not already entered the dispensing options menus, do steps 1 and 2 in Selecting Dispensing Options on page 8. 2.
Operation Locking and Unlocking the Trigger Dispensing Fluid in Manual Mode The trigger on this dispense valve has a locking mechanism. In Auto mode, the unit stops dispensing when the entered amount has been dispensed. In Manual mode, the trigger does not automatically unlock; you must unlock it manually. To lock the trigger, press on the part of the trigger that has the textured grip (see below) until you feel it click into the locked position.
Operation Dispensing Fluid in Auto Mode CAUTION Before you begin a preset dispense cycle, make sure AUTO is displayed. If you do not see AUTO on the display, you are not in the Auto dispense mode, and fluid flow will not stop when the auto preset amount is dispensed. 1. Press the Auto/Reset button. The display wakes up if it was asleep, and AUTO and the stored preset dispense amount are displayed. The factory default is 0.00.
Troubleshooting Relieve the pressure before you check or repair the meter. Be sure all other valves and controls and the pump are operating properly. Problem WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5. Cause Solution Battery icon is displayed. Battery is low. Replace the battery. See Replacing the Battery on page 16. Battery icon is blinking, and bAtt is blinking. Battery is dead.
Troubleshooting Problem Cause Solution Meter leaks from: Cover/Control Poor swivel (3)/hose connection. Apply PTFE tape (leave minimum 2 engaged threads uncovered for electrical continuity) or sealant to threads of hose and tighten the connection. See step 9 in Installation Procedure. Poor swivel (3)/meter housing connection. Torque the fitting to 20--25 ft.lb. Damaged valve stem (16) assembly. Replace or clean valve stem and O--rings. See Servicing the Valve. Poor seal at meter housing plate.
Troubleshooting Error Codes Error codes are listed below. Even in an error condition, the unit keeps track of the amount dispensed. With any error code displayed, as shown at right, you can D Press the Manual/Reset button.
Service Replacing the Battery Replacing the Filter The filter (25) is replaceable. To replace the filter, do the following: WARNING FIRE AND EXPLOSION HAZARD Only replace the battery in a non-hazardous location, away from flammable fluids or fumes. You may order battery Part No. 113716 separately.
Service Servicing the Valve Replacing the Automatic Nozzle Valve Repair Kit 240453 is available and can be ordered separately. See the Parts List on page 18 and the Parts Drawing on page 19. The parts with asterisks next to their reference numbers are available in the Valve Repair Kit. The automatic nozzle (5b, 6b, or 7b) is not serviceable. If it leaks, replace it as follows: When you are repairing the valve with new parts from the Valve Repair Kit, use all of the new parts.
