A PRESSURE HAZARD MAY EXIST EVEN WHEN THE PUMP IS NOT RUNNING. PRIOR TO REMOVING HOSES OR CAPS FROM PUMP CONNECTIONS, RELIEVE PRESSURE BY OPENING DRAINS. BLEEDER VALVES SHOULD ALSO BE USED WHEN CONNECTING TO AN INTAKE FROM A PRESSURIZED SOURCE. ALWAYS FOLLOW LOCAL GUIDELINES FROM THE AHJ AND THE APPARATUS MANUFAC- TURER.

2. INTRODUCTION This section provides an overview of the Hale Master Intake Valve (MIV) currently in production. Additionally, the section provides information about How to Use This Manual and the Principles Of Operation for the Master Intake Valve. 2.1. Overview The Hale Master Intake Valve is a NFPA compliant large diameter intake valve that is mounted in the pump suction tube behind the pump operator panel.
Design of the relief valve permits the discharge to be piped behind the operator panel for in- creased operator and/or bystander safety. 2.2. Installation The unique design of the Hale Master Intake Valve permits installation in the fire pump suction tube behind the pump compartment panel using a minimum of space.
Figure 2. Component Part Identification (Manual Valve) Bottom mounted valves are installed to bottom of the suction tube extension for use with front and/or rear suctions (Figure 4). The valve may also be installed in-line or it may be used with large auxiliary pumps. Optional Hale 6-inch NPT threaded flanges are available for use in these installations.
1. Determine the location of interferences on the fire pump and the pump operator panel. Proper planning and layout of the pump operator panel will reduce the potential interfer- ences for other operating equipment. The plate drawing, FSG-PL-01491, provides the overall mounting dimensions for the Hale MIV.
3. Apply a coating of Loctite® #243 or equal thread locking compound and install the 7/16- 14 UNC X 5-¼ inch long studs into two holes of the suction tube extension. Torque the studs to 40 lb-ft (54 N-m). These studs are used to support the valve and suction tube during installation.
NOTE WHEN THE VALVE BODY IS INSTALLED MAKE SURE THE VALVE DISC IS NEXT TO THE SUCTION TUBE EXTENSION. THE RELIEF VALVE, DRAIN VALVE, AIR BLEEDER VALVE AND PRIMING VALVE MUST BE LOCATED ON THE INLET SIDE OF THE VALVE. Figure 4.
8. Coat the threads of eight 7/16-14 x 5-¾ inch long grade 8 cap screws with Loctite® #242 or equal and insert through holes in the flange and thread into bottom opening of suction tube extension. Torque cap screws and nuts to 40 ft-lb (54 N-m). 2.2.3 Plumbing Relief Valve MALE THREADS ON RELIEF VALVE OUTLET ARE SHARP AND CAN CAUSE SEVERE...
2. Use appropriate hose or pipe on the 2-½ inch NPT outlet of the relief valve to direct the discharge of the relief valve away from the operator position. DO NOT restrict the flow of water through this pipe. Make sure the pipe is properly supported to withstand the po- tential force of water that can flow from the relief valve.
4. Install the ¼ inch NPT X 3/8 inch tube push on elbow into the hex outlet of the air bleeder valve. To prevent damage to the valve body, hold the hex outlet on the valve with a wrench while tightening elbow. Make sure the outlet of the elbow is facing away from the valve handle.
12. Connect a length of 3/8 inch O.D. tubing from the fitting on the Hale MIV valve body to the fitting on the inlet of the air bleeder valve. 13. Connect a length of 3/8 inch O.D. tubing from the outlet of the elbow on the outlet of the air bleeder valve and route this tubing away from the operator position.
ORIGINAL WIRING. WIRING DIAGRAMS ARE PROVIDED IN THE TROUBLESHOOTING SECTION OF THIS MANUAL. FOLLOW NFPA REQUIREMENTS FOR APPARATUS ELECTRICAL WIRING. USE MINIMUM 14 AWG, TYPE SXL OR GXL (SAE J1128) WIRE. THE WIRING SHALL BE PROTECTED USING 289 F (143 C) MINIMUM FLAME RETARDANT, MOISTURE RESISTANT LOOM OR BRAID.
a. The first position is for 76-81 inch truck panel widths. The extension is pushed on until the first hole in the extension lines up with the hole in the gearbox hand- wheel shaft. b. The second position is for 70-76 inch truck panel widths. The extension is pushed on all the way until the second hole in the extension lines up with the hole in the gearbox handwheel shaft.
Table 1. Relief Valve Adjustment Settings NO. OF 360 DEGREE OPENING PRESSURE TURNS FROM ZERO (PSIG) 10. Tighten nut to lock adjusting shaft at the desired setting. 11. All pressure settings are approximate. 12. Repeat steps 4-6 to test desired pressure settings. 13.

How To Use This Manual This manual was developed for the purposes of FAST team and OEM support. This manual pro- vides information and procedures to perform MIV maintenance (preventive and corrective).
PER NFPA 1962 REQUIREMENTS, LARGE DIAMETER HOSE USED TO SUPPLY A PUMPER FROM A HYDRANT, OR ANOTHER PUMPER SHALL BE CONNECTED TO THE PUMPER(S) AND HYDRANT WITH A SLIGHT DOWNWARD BEND TO AVOID KINKING WHEN THE WATER IS TURNED ON. PER NFPA 1962 REQUIREMENTS, LARGE DIAMETER HOSE MARKED “SUPPLY HOSE”...
WHEN THE ELECTRIC MOTOR DRIVEN VALVE IS OPERATED THE MANUAL OVERRIDE HANDWHEEL WILL TURN. KEEP HANDS, FEET OR LOOSE CLOTHING AWAY FROM THE HANDWHEEL TO PREVENT ENTANGLEMENT. 1. Energize 12 vdc power to pump operator panel. 2. To open valve, push toggle switch (figure 8) to the OPEN position and hold until the green OPEN indicator lights (while in between open/close, the lights will not be luminated).
Figure 8. MIV PANEL PLACARD MOUNTING DIMENSIONS 2.5.5 Cold Weather Operation During extremely cold weather the pump and Hale MIV must be completely drained to prevent ice formation and possible damage. During cold weather operation use the following procedure for continued reliable operation. 1.
3. PREVENTIVE MAINTENANCE Hale Products recommends the preventive maintenance and inspections listed in Table 2. Table 2. Recommended Preventive Maintenance Interval Check/Test Action Required Item(s) Required After Each Use Visual Check Inspect the valve to make sure there is no de- None bris caught between the valve body and valve disc.

4. To lubricate Port 1, remove 1/8” BSPP plug, complete 2.5 revolutions using MIV motor (manual or electric). Spray 2-3 spurts of Super Lube® Multi-Purpose Synthetic Grease Food Grade with Silicone or equal. Reinstall 1/8” BSPP plug. 5. Return MIV to closed position. 6.
4. CORRECTIVE MAINTENANCE This section provides general repair guidelines, MIV system troubleshooting, and bench repair instructions for the following MIV components. • Valve Disc • Switches • Relief Valve 4.1. General Repair Guidelines The following subparagraphs provide general guidelines to be utilized and/or followed whenever the maintenance procedure being performed is associated with the type of information/ instruc- tions provided in these subparagraphs.
