Appendix F
A % tier disable is also provided. The % tier disable sets the percent of overlap of the spray volume as the
volume per minute required decreases. Thus, if the % tier disable is set to 10% and the tier 2 switch point is set
at 30 GPM [113.6 L/min], then tier 1 and 2 will switch to tier 2 only when the desired volume decreases to 27
GPM [102.2 L/min].
So, for rates in gallons per minute:
30 GPM – (10% of 30 GPM) = 30 GPM – 3 GPM = 27 GPM
or, for rates in liters per minute:
113.6 L/min – (10% of 113.6 L/min) = 113.6 L/min – 11.3 L/min = 102.3 L/min
In operation, as the volume per minute increases, the following boom tier switching will occur.
•
10 GPM [37.8 L/min] increasing to 20 GPM [75.7 L/min] tier 1 turned on
•
20 GPM [75.7 L/min] increasing to 30 GPM [113.6 L/min] tier 2 turned on
•
30 GPM [113.6 L/min] increasing to maximum flow rate tier 1 and 2 turned on
10 - 20 GPM

In operation, as the volume per minute decreases, the following boom tier switching will occur.
•
Maximum flow rate decreasing to 27 GPM [102.2 L/min] tier 1 and 2 turned on
•
27 GPM [102.2 L/min] decreasing to 18 GPM [68.1 L/min] tier 2 turned on
•
18 GPM [68.1 L/min] decreasing to 10 GPM [37.8 L/min] tier 1 turned on
