40 Instructions for installation and servicing ecoTEC 839592_12

• Release water from the system until the system design

pressure of 1.0 bar is attained. (The actual reading on the

digital pressure gauge should ideally be 0.5 bar plus an

additional pressure corresponding to the highest point of

the system above the base of the boiler – 10 m head equals

an additional 1 bar reading on the pressure gauge. The

minimum pressure should not be less than 1 bar in any

installation.) If the system is to be treated with an inhibitor it

should be applied at this stage in accordance with the

manufacturer’s instructions.
