CAUTION: WHEN YOU INSTALL THE DEACTIVATION SCREW ON THE VALVE, TIGHTEN THE SCREW WITH YOUR HAND BEFORE YOU TORQUE IT. IF YOU DO NOT OBEY THIS PRECAUTION, YOU CAN CAUSE DAMAGE TO THE SCREW AND THE VALVE.

CAUTION: BEFORE YOU INSTALL THE DEACTIVATION SCREW, MAKE SURE THAT THE PREFORMED PACKING IS INSTALLED ON THE DEACTIVATION SCREW.

(11) Install deactivation screw No.1 as follows:

NOTE: If the adaptor (T19) is installed, the deactivation screw has a preformed packing.

(a) Install deactivation screw No.1 on the bleed-pressure regulator valve.
(b) TORQUE deactivation screw No.1 to between 0.6 and 0.4 m.daN (53.10 and 35.40 lbf.in )

.
(12) Install the blanking cap on the test port of the bleed-pressure regulator valve.
(13) TORQUE the blanking cap to between 0.8 and 0.65 m.daN (70.80 and 57.52 lbf.in )

(14) Safety the deactivation screw and the blanking cap with the lockwire 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
