3. Technical specifications
Table 1: Technical data - Indirect Cylinders
Notes:
1: at 3 bar water inlet pressure
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 is only rated 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 supplied will have to be sourced.
