NR = Not Recommended
Notes:
1. All throw data figures are approximate.
2. NR = not recommended at these mounting heights.
3. Nozzles are not available on units below size 100 MBh.
4. Nozzles are available for High Efficiency units. Specify High Efficiency when ordering due to difference in nozzle
configuration.
