6.5.1 Connecting pipe diameter of low temperature kits
The inlet pipe and outlet pipe of the low temperature kits are connected by 3/8 inch globe valve, and the actual
on- site connection pipeline refers to the requirements of the nozzle in the installation instructions. The kit is
connected with the liquid pipes of the indoor unit and the outdoor unit respectively, When the diameter of the
liquid pipe of the indoor and outdoor unit of the air conditioner is different from that of the globe valve, it is
necessary to enlarge or shrink the liquid pipe of the internal and external machine respectively and then weld one
end of the liquid pipe of the low temperature kits, and the other end of the liquid pipe of the low temperature kit
is threaded to its own globe valve through the trumpet thread.
