DC Inverter Multi VRF System
4.3.5 Installation of Y-type Branch
(1) Y-type Branch.
(2) Y-type branch has several pipe sections with different dimension, which facilitates to match
with various copper pipes. Use pipe cutter to cut in the middle of the pipe section that is of
proper dimension and remove burrs as well. See Fig.4.17.
(3) Y-type branch must be installed vertically or horizontally.
Branch shall be isolated by insulating material that can bear 120°C(248°F) or even higher
temperature. The attached foam of branch cannot be taken as insulating material.
4.3.6 Thermal Insulation for Pipeline
(1) For multi VRF system, every copper pipe should be labeled so as to avoid misconnection.
(2) At the branch inlet, leave at least 500mm(19-3/4inch) straight pipe section.
