Series 6A Operation & Maintenance – Technical Data

6A O & M : 35

Technical specifications

1)

During commissioning at ≤ 0 °C (≤ 32 °F) make sure that the valves are

flushed long enough with the dry medium.

2)

At ≤ -10 °C (≤ 14 °F) the display refresh rate of the indicator is limited. Only

T4 is permissible when using I

y

module.
