3-3.6.1 Nitrogen Actuator, Mounting Bracket and Adapter, P/N WK-877940-000,
P/N WK-877845-000 and P/N WK-699205-010 respectively
Gas pressure from a nitrogen cylinder is routed to the pressure operated control head mounted
on each HFC-227ea cylinder. When the control head on the remote nitrogen cylinder is
actuated, the HFC-227ea cylinder will be activated, causing HFC-227ea to be discharged from
the cylinder.
The nitrogen cylinder is used in multiple cylinder and main/reserve systems. When activated
by a control head, gas pressure is routed from the nitrogen cylinder to pressure operated
control heads mounted on each HFC-227ea cylinder, resulting in a complete system discharge
(see Figure 3-22).
