2. Install a pressure operated control head with flexible actuation hose attached to the cylin-
der actuation port.
WARNING
When attaching the Lever/Pressure operated control head to the valve, the
swivel nut must be tightened to a toque of 55ft·lb. Failure to tighten the swivel
nut may result in leakage during actuation.
WARNING
Ensure that the pilot line is non-pressurized and the actuating pins are in the
retracted (SET) position. Failure to follow this procedure will cause the HFC-
227ea cylinder to discharge accidentally when the control head is installed on
the cylinder valve.
