7.5.1 Draining Condensate
1) Gradually open the drain plug and drain the
transmitter pressure-detector section.
(See Figure 7.2)
2) When all accumulated liquid is completely
removed, close the drain plug.
3) Tighten the drain plug to a torque of 34 to 39
N·m {3.5 to 4 kgf·m}.
7.5.2 Venting Gas
1) Gradually open the vent screw to vent gas from
the transmitter pressur-detector section.
(See Figure 7.2)
2) When the transmitter is completely vented,
close the vent screw.
3) Tighten the vent screw to a torque of 10 N·m
{1 kgf·m}.
