- Page 1 STYLE 5148 MERCURYMASTER OSCILLATING NOZZLE INSTALLATION, OPERATING, AND MAINTENANCE INSTRUCTIONS The following is intended to provide the basic instructions for installation, operation, and maintenance. Read and understand these operating instructions before use. Read and follow the operating instructions before use.
- Page 2 • Indicates a hazardous situation which, if not avoided, WILL result in death or serious injury. • Indicates a hazardous situation which, if not avoided, COULD result in death or serious injury. • Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. • Addresses practices not related to personal injury. • This product is intended for use with the Mercury Quick Attack portable monitor only. Read and follow the operating instructions for the monitor before use. • Read and follow the operating instructions for Style 5148, 500gpm before use. • Use only for firefighting by trained operators. • Do not exceed the maximum pressure or flow ratings for the monitor. • Make sure monitor legs are fully deployed, and all three spikes are in contact with the ground and safety strap is secure before use. • Make sure the monitor is pointed in a safe direction before flowing the water. • Make sure the monitor valve is closed when advancing the monitor. Do not move or lift the monitor while flowing.
- Page 3 • At pressures below the rated pressure indicated on the label, the nozzle will have reduced flow and reach. Be sure you have enough flow and pressure for the situation (See IFSTA and NFPA manuals for guidelines). • At pressures below the rated pressure, the oscillating nozzle may not oscillate. Obstructions to the flow through the nozzle will also cause the nozzle to not oscillate. • Not for use on electrical fires. May cause electrocution. • Ensure the thread on the nozzle swivel is matched to the thread on the Mercury Quick Attack outlet. Do not use thread adapters between the monitor and nozzle. • Read and follow the tip pressure and flows in the operating instructions before use. • Before operating the oscillating nozzle, make sure the connecting rod in Figure 6 is parallel with the water way. Failure to do so may cause the oscillating mechanism to bind during operation. • Do not adjust oscillating angle while oscillating. • If any tags or bands on the nozzle are worn or damaged and cannot be easily read, they should be replaced.
- Page 4 Bracket Installation 1. Using a hammer and a 1/8” punch remove the roll pin on the end of the handle closest to the outlet of the Mercury Quick Attack as shown in Figure 1. 2. Rotate the handle upward and out of the way to gain access to the top trunnion as shown in Figure 2. 3. Using a 5/8” open end wrench remove the top trunnion and the trunnion on the left side of the Mercury Quick Attack.
- Page 5 FIGURE: 3 FIGURE: 4 Fully assembled monitor with bracket Elevation Lock Knob and Lower Trunnion Installation 1. When looking from the inlet towards the outlet of the monitor, using a 5/8” open end wrench remove the right side trunnion from the elevation joint. Apply Permabond HH120 or equal thread locking to the lock knob trunnion and install the pre-assembled locking knob in its place. When tightening the lock knob trunnion make sure the lock knob is fully loosened to allow the trunnion to be completely tightened.
- Page 6 FIGURE: 5 Lock Knob installed Lower trunnion installed Nozzle Installation • Ensure the thread on the nozzle swivel is matched to the thread on the Mercury Quick Attack outlet. • Before operating the oscillating nozzle, make sure the connecting rod in figure 6 is parallel with the water way. Failure to do so may cause the oscillating mechanism to bind during operation. 1. Tighten the nozzle swivel to the outlet of the Mercury Quick Attack. The swivel must be tight to keep the nozzle from loosening during operation. 2. The nozzle must be oriented as shown in Figure 6 to ensure proper alignment of the connecting rod. 3. Following the operating instructions, flow water through the nozzle and monitor assembly to ensure the oscillating mechanism does not bind during oscillation. 4. The nozzle is ready for use.

- Page 7 FIGURE: 6 Connecting Rod Operating Instructions • Charge all lines slowly to facilitate a controlled water pressure build-up during start-up. Open and close slowly. Rapid opening will produce a sudden thrust. Rapid opening or closing can cause water hammer. Have enough firefighters on the line to safely control the reaction force created by the stream • Make sure the legs are fully deployed and all three spikes are in contact with the ground and safety strap is secure before use. • At pressures below the rated pressure, the oscillating nozzle may not oscillate. Obstructions to flow through the nozzle will also cause the nozzle to not oscillate. • Do not adjust oscillation angle while oscillating. 1. The flow setting for this nozzle is 500gpm/1900lpm with a pressure of 75psi/5bar at the inlet to the nozzle. 2. With the oscillation selector set to the OFF position, select the desired oscillation angle of 20° or 40° by pushing the center release button on the T-handle. As shownin Figure 8. 3. Center the monitor and nozzle on the target. The nozzle will oscillate symmetrically about the center position.
