Bulletin 71.1:MR95 Installation The MR95 Series regulators may be installed in any position, as long as flow will be in the same direction as that indicated by the body arrow. The Types MR95H, MR95L, MR95HT and MR95HP regulators should be installed so that their spring case vents are protected from anything that might clog them. Emerson Process Management Regulator Technologies, Inc. (Emerson™) provides an instruction manual with every regulator shipped.
