NOTES:
• Values for use with 5.75" straight reducers.
How to use this Design Guide:
• For some systems, it may be advantageous for the designer to calculate the system hydraulics using shorter equivalent lengths associated with fewer than the
maximum allowable number of bends. In this case, the designer may select a design number of bends for the job and use the associated equivalent length
from the design guide to determine the system hydraulics.
• It is possible that the actual installed condition of some of the flexible drops may have more bends than the designer selected. When this happens, the design
guide may be used to find equivalent lengths based on the actual installed number of bends for particular sprinkler installations. The system hydraulics can be
recalculated using actual equivalent lengths to verify the performance of the system.

FM NOTES:
• Series AH1 has been tested and Approved by FM Global for use in wet, dry and preaction systems per NFPA 13, 13R, and 13D and FM data sheets 2-0, 2-5,
and 2-8. FM 1637 and Vds standards for safety include, but are not limited to, pressure cycling, corrosion resistance, flow characterisitics, vibration resistance,
leakage, mechanical and hydrostatic strength.
• Differences in equivalent lengths are due to varying test methods, per FM 1637 and VdS standards. Refer to these standards for additional information
regarding friction loss test methods.
• EXAMPLE: A 48-inch hose installed with two 30° bends and two 90° bends at a 7-inch bend radius is permitted and considered equivalent to the data in the
table shown above. In this example, the total number of degrees is 240°, which is less than the allowable 270°.

Install 90 Degree Pull Elbow
A. If the pull elbow did not come with a threaded end attach a ½” close nipple to the 90 degree pull elbow.
B. run the electrical leads from the gearbox through the 90 degree pull elbow and then attach the 90 degree pull elbow by inserting
the close nipple into the threaded port on the gearbox.
C. If the cover plate was removed reinstall the cover plate and turn the 90 degree pull elbow to a 45 degree angle upwards to allow
room for LB Conduit body installation.
