Vertical Step 2:
The vessel assembly should then be positioned and checked to ensure there is
sufficient space to install the upstream line-in kit between the stopcock and
pressure vessel inlet.
Monobloc 22/28mm Upstream line-in kit
The Monobloc upstream line-in kit includes:
1 - Monobloc unit
2 - Pressure gauge (upstream)
3 - Pressure gauge (downstream)
4 - Mainsboost vessel connector (see step 1)
5 - Isolation valve (See step 1)
NOTE: the Monobloc can be installed either horizontally or vertically but not upside
down. There are pressure gauge ports on both sides of the Monobloc to allow the
pressure gauges to be visable in any orientation. Follow the directional flow arrows
on the Monobloc to ensure correct installation.
Upstream line-in kit 35/42/54mm
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 valve)
6 - Mainsboost vessel connector (see step 1)
7 - Isolation valve (See step 1)
