6.9 Connecting the Refrigerant Lines and Refrigerant Charge
6.9.1 Connecting the Refrigerant Lines
• To connect the refrigerant lines use only "L" type sealed, dehydrated copper refrigerant
tubing. No other type may be used. The use of other types of tubing will void the
manufacturer's warranty.
• Do not open service valves and do not remove protecting caps from tubing ends until all the
connections are made.
• Take care to avoid links or flattening of the tubing.
• Bend tubing with special bending tools to avoid the formation of sharp bends.
• Keep the tubing free of dirt, sand, moisture and other contaminants to avoid damaging the
refrigerant system.
6.9.2 Flaring and Connecting
• Remove the protecting cap from the flare fitting.
• Remove the protecting cap from the tubing and cut to the required length. Make sure that
the cut is perpendicular and clean, without burrs.
• Slip the flare nut on the tubing and flare the tube end, using standard flaring tools.
• Tighten the nut until resistance is met. Mark the nut and the fitting. Using a suitable wrench,
tighten an additional 1/4 turn. Use the following specified torque, according to connection
size.
• The valves on the outdoor unit must remain closed until all four connections have been
made.
