Caution
(1) Check the element periodically and replace it with a new one if necessary. If it is found that outlet
pressure drops lower than the normal condition or the flow is restricted during operation, check the
condition of the element.
(2) For the N.C. type auto drain, when there is no pressure, drain which does not operate the auto
drain mechanism will remain in the bowl. It is recommended to release the residual drain manually
at the end of the working day.
