14. Since this transmitter is designed to be self draining and self venting with vertical impulse piping connec tions neither draining nor venting will be required if the impulse piping is configured appropriately for self draining or self venting operation If condensate or gas collects in the transmitter pressure detector section the measured pressure may be in error If it is not possible to configure the piping for self draining or self venting operation you will need to loosen the drain vent screw on the transmitter to completely drain vent any stagnated liquid gas However since draining condensate or bleeding off gas gives the pressure measurement disturbance this should not be done when the loop is in operation N WARNING Since the accumulated liquid or gas may be toxic or otherwise harmful take appropriate care to avoid contact with the body or inhalation of vapors 7 5 1 Draining Condensate 1 Gradually open the drain screw or drain plug and drain the transmitter pressure detector section See Figure 7 5 1 2 When all accumulated liquid is completely re moved close the drain screw or drain plug 3 Tighten the drain screw to a torque of 10 N m and the drain plug to a torque of 34 to 39 N m Drain screw When you loosen the drain screw or drain plug the accumulated liquid will be expelled in the direction of the arrow F0706 EPS Figure 7 5 1 Draining the Transmitter 7 OPERATION
