Page 9 Removing protective caps and seals Before installation, be sure to remove all protective seals and caps. (Found in ２ locations, on the product inlet and outlet(s).) CV10-M2/CT20 CT20D Installation angle Install the product vertically, so that the arrow mark on the body points horizontally in the direction of flow.
Page 10 Drainage port usage example The threaded condensate drainage port at the bottom of the body makes possible installation of a blow valve or steam/air trap. Because the condensate drainage port is located on the primary side of the product, condensate flowing in the primary side piping can quickly be eliminated, contributing to prevention of valve seat erosion and rapid start-up of the equipment.
Page 11: Maintenance
Maintenance Caution Take measures to prevent people from coming into direct contact with product outlets. Failure to do so may result in burns or other injury from the discharge of fluids. When disassembling or removing the product, wait until the internal pressure equals atmospheric pressure and the surface of the product has cooled to room temperature.
Page 12: Disassembly/Reassembly
Disassembly/Reassembly Caution When disassembling or removing the product, wait until the internal pressure equals atmospheric pressure and the surface of the product has cooled to room temperature. Disassembling or removing the product when it is hot or under pressure may lead to discharge of fluids, causing burns, other injuries or damage.
