• IMPORTANT: Do not braze any fitting with the TEV sensing bulb attached.
• Braze the tubing between the outdoor unit and indoor coil. Flow dry nitrogen
into a service port and through the tubing while brazing.
• The service valves are not backseating valves. To open the valves, remove the
valve cap with an adjustable wrench. Insert a 3/16" or 5/16" hex wrench into the
stem. Back out counterclockwise.
• Replace the valve cap finger tight then tighten an additional 1/2 hex flat for a
metal-to-metal seal.
