Notes:
1: at 3 bar water inlet pressure the cylinder is filled with the maximum amount of water. Controlled by a 3 Bar P.R.V.
2: at 80°C - +/- 2°C
3: Although the primary coil pressure rating is 1.0MPa (10bar) the 2 port zone valve and coil compression nuts supplied
with the cylinder are only rated at 0.86MPa (8.6 bar). If the cylinder is to be plumbed into a system delivering 1.0MPa (10
bar) a suitable 2 port zone valve and the coil compression nuts will have to be sourced.
