When connecting, smear both inside and outside of the flare nut with refrigeration oil, screw it
hand tight and then tighten it with the spanner.
Refer to Table 9 to check if the wrench has been tightened properly (too tight would mangle the

Examine the connection pipe to see if it leaks, then take the treatment of heat insulation, as
shown in the Fig.15.
Use the medium-sized sponge to insulate the coupler of the gas pipe.
