* 7-inch/178-mm minimum bend radius (tested with standard 5 3/4-inch/146-mm length straight reducer)
‡ 3-inch/76-mm minimum bend radius (tested and UL Listed only with standard 5 3/4-inch/146-mm length straight reducer)
# 3/4-inch/DN20 outlet data shown with K14.0 - For other K-factor friction loss data, refer to Victaulic publication 10.95
For the UL Listing, when the 48-inch/1220-mm length bracket is used with the Series AH1 or AH1-CC Flexible Hose, the maximum sprinkler K-factor is K8.0 and the
maximum spacing is 30 inches/762 mm
§ A higher number of bends may be permitted, provided the sum of degrees is equal to or less than the total maximum allowable degrees of bends
(e.g. Two 90° bends equal 180°. Three 90° bends equal 270°). The minimum bend radius and maximum number of 90° offset (bends), stated in these installation instructions,
refer to the final installed condition of the hose.
For friction loss data for elbows, refer to Victaulic publication 10.95.
NOTE:
Differences in equivalent lengths are due to varying test methods, per UL 2443 and FM 1637 standards. Refer to these standards for additional information regarding
friction loss test methods.
When using a No. 101 90° Elbow or a No. 102 Straight Tee in place of a Style 108 Coupling on the end of a Series AH1-CC Flexible Hose, the friction loss data shown
above shall be added to the No. 101 or No. 102 friction loss data published in Victaulic publication 10.54.
