5 Refrigerant Piping Requirements
The main fluid connections are flange fittings with a factory installed plate. These connections may be at the top of the unit.
• Field installed refrigerant piping must be installed in accordance with local codes and must be properly
assembled, supported, isolated, and insulated. Avoid piping runs through noise sensitive areas, such as office
walls and conference rooms.
• Refer to specific text and detailed diagrams in this manual for other unit specific piping requirements.
• All piping will be elevated above the unit and must be arranged so that it offers the least resistance. Careful
planning of the piping layout above the raised floor is required. When installing piping above the unit, we
recommend installing the pipes in a horizontal plane rather than stacked one above the other.
• Whenever possible, the pipes should be run parallel.
• Install shutoff ball valves on the inlet and outlet pipes to ease maintenance.
• Install optional thermostats and pressure gauges on the inlet and outlet pipes.
