Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P180-05) supplied with the product. Installation note: The trap is designed for installation in vertical lines with the flow downward to ensure self-draining operation. Do not expose the element to superheat conditions since over-expansion may result. Suitable isolation valves must be installed to allow for safe maintenance/replacement.
