DC Inverter Multi VRF System 4.3 Installation of Connection Pipe 4.3.1 Precautions for the Installation of Connection Pipe (1) Conform to the following principles during pipe connection: Connection pipe should be as short as possible, so is the height difference between indoor and outdoor units. Keep the number of bends as little as possible. - Page 16 DC Inverter Multi VRF System (2) Direct the flared part of copper pipe to the center of screwed joint. Twist on the flared nut tightly by hand, as in Fig.4.11 (Make sure indoor pipe is correctly connected. Improper location of the center will prevent flared nut from being securely twisted. Thread of nut will get damaged if the flared nut is twisted forcibly).
