Connecting Method
Installing the Y-joint
Insulating the branch joint
Y-joint & liquid side & gas side of the outdoor unit
Attach the insulation provided with a branch joint to the insulation supplied in the eld
without a gap. Wrap the connected part with an insulation (Field supply) of a thickness of at
least 10mm.
Use an insulation with the heat resisting temperature over 120°C.
Wrap the branch joint with an insulation of a thickness of at least 10mm.
When insulating in high humidity(higher than 30°C, 80%), wrap the supplied insulation with
more than 10mm of extra insulation such as Polyethylene Foam or other similar material.
Wrap the connected part between the Outdoor joint and the gas side of the outdoor unit to
prevent it from defrosting. Wrap gas side pipe of the outdoor unit wholly to prevent it from
dewing.
Attach the adhesive insulation tape to the pipe
as shown in the picture after insulating the pipe.
