4.3.4 Outdoor Pipe Connection
(1) Pipe connection for GMV-36WL/C-T(U), GMV-48WL/C-T(U).
Twist the flared nut on the connection pipe of outdoor valves. Twisting method is the same as for
indoor pipe connection.
During engineering installation, the connection pipe inside the unit must be wrapped by insulation
sleeve.
According to customer requirement or space limit, outlet pipe can be installed from the front,
right or rear side.
(2) Pipe connection for GMV-60WL/C-T(U).
As shown in Fig.4.14 and Fig.4.15, open the outermost soundproof cotton and place a fire barrier
between compressor and straight pipe. Use a soldering gun to unsolder straight pipe 1 and straight
pipe 2. Install connection pipe 1 and connection pipe 2 to the corresponding position and then seal
the apertures with welding rod. First weld the liquid side connection pipe and then weld the gas side
connection pipe. During welding, it's necessary to use wet gauze to wrap up the two cut-off valves.
Make sure the flame won't burn the soundproof cotton or other components.
