Tyco DN40 Manual page 7

TFP1460
NOTES:
1. Use only the 2" Model CV-1FR Riser Check
Valve with 1-1/2" and 2" DV-5 Valves. Use
corresponding sized Model CV-1FR Riser
Check Valves for 3"-8" Model DV-5 Valves.
2. Nipples 1-7 vary in length relative to the
Model DV-5 size and Riser Check Valve
used. Select per the appropriate table. All
other nipples packed unassembled shall be
installed per the appropriate trim exploded
view, Figure 2A Part 1, 2, or 3.
3. Install subassemblies in alphabetical order.
4. See Figure 2 of TFP1305 for Deluge Valve
Port identification.
5. Route all Tubing to Drip Funnel.
6. When DV-5 trips, the Fail-Safe Valve opens,
partially diverting the diaphragm supply to
drain, allowing diaphragm chamber to remain
de-pressurized after a decrease in system
flow.
