Footnotes
1
Part number shown is the base part number. For complete part number, refer to current Viking price list schedule.
2
Metric K-factor measurement shown is when pressure is measured in Bar. When pressure is measured in kPa, divide the metric K-factor shown by 10.0.
3
This chart shows listings and approvals available at time of printing. Check with the manufacturer for any additional approvals.
4
cULus Listed for use in the U.S. and Canada.
5
To determine “Minimum Water Supply Requirement” for areas of coverage where length and width of actual sprinkler spacing are not equal, select the “Maximum
Sprinkler Spacing” from the chart that is equal to or greater than the larger of the actual spacing (length or width) dimensions used. Example: When using 10’-6” x
13’-0” sprinkler spacing, provide the “Minimum Water Supply Requirement” listed in the chart for 14’-0” x 14’-0” spacing. For areas of coverage smaller than shown,
use the “Minimum Water Supply Requirement” in the appropriate hazard group for the next larger area listed. The distance from sprinklers to walls shall not exceed
one-half the “Maximum Sprinkler Spacing” listed for the “Minimum Water Supply Requirement” used.
6
cULus Listed as corrosion-resistant.
