Pipe
Size
Minimum pipe length required to install the
upstream line-in kit (mm) (A)
22 mm 480 mm
28 mm 580 mm
35 mm 630 mm
40 mm 735 mm
54 mm 820 mm
Upstream line-in kit
The upstream line-in kit includes:
1 - inline strainer
2 - pressure gauge (upstream)
3 - double check valve
4 - pressure reducing valve
5 - pressure gauge (fitted to pressure reducing
