Ulease don-t let the pipe and the parts in the unit collide each other4
Yhe connection between outdoor liquid pipe and the distributing pipe is flared type4 Ulease
expand the pipe with the special tool for W:76F after installing the expanding nut4 Gut if the
projecting pipe length has been adjusted with the copper pipe gauge2 you can use the original
tool to expand the pipe4
Xince the unit is with W:76F2 the expanding oil is ester oil2 not the mineral oil4
\hen connecting the pipes2 close the valves fully4
Urotect the pipe end against the water2 impurity into the pipes .welding after being flat2
or being sealed with adhesive tape/4
Gend the pipe as large semi3diameter as possible.over : times of the pipe diameter/4
\hen connecting the expanding pipe2 fasten the pipes with double3spanner4 Yhe torque refers
to the former info4

Xeal the pipe end with adhesive tape or the stopper

Yhe outdoor gas pipe and the refrigerant distributing pipe2 as well the refrigerant distributing
pipe and the branch pipe should be welded with hard solder4
\eld the pipe at the same time charge the nitrogen4 Tr it will cause a number of impurity .a
film of oxidation/ to clog the capillary and the expansion valve2 further cause the deadly failure4
