Ultra-Aire SD12 Installation Instructions
When installing the line set:
• Make sure the lines are suitable for use with R410a.
• Do not crush the lines and always allow a minimum bend radius of 2 inches.
• Keep the ends of the lines covered to prevent dirt and debris from entering the lines during installation.
• Secure the line set to the building with isolating hardware to prevent vibration transmission to the building.
• Seal and isolate the opening(s) where the line set is routed into the building.
• Insulate the gas (suction) line to prevent water condensation on the gas line.
• Flush the lines with an inert gas before and/or during brazing to prevent oxidation inside the lines.
• Release the inert gas holding charge and remove the plugs in the dehumidifier lines before brazing.
• Do not overheat the lines connected to the dehumidifier or the condensing unit when brazing.
• Be aware of the relative location of the dehumidifier (Indoor unit) and condensing unit (Outdoor Unit) when
installing the line set.
