runs along the bottom of the filter module. All of the sprinkler heads are supplied through a single
coupling, welded near the bottom of a lower side panel.
Refer to Table 330.6.1 to determine the water flow rate and the size and number of couplings required for
your system.
Note: If you are supplying more than one sprinkler connection coupling with a single
supply pipe, the supply pipe must be sized to accommodate the required flow rate. Check local
codes and NFPA for requirements.
Apply Teflon tape to the supply pipe and connect it to the sprinkler connection coupling(s). Turn on water
supply and inspect all connections for leaks.
Note: Water leaks in the collector will cause cartridge
failure and hopper flow problems.
