Insulating The Refrigerant Tubing - Sanyo SPW-X483GH56 Installation Instruction

8-4. Insulating the Refrigerant Tubing

Always insulate tubes after
draining water and complet-
CAUTION
ing leak tests on all connec-
tion points.
Important
To avoid condensation and water leaks, both the wide
tube and narrow tube (only for heat pump) must be
insulated with the supplied insulation materials.
Taping the flare nuts
Wind the white insulation tape around the flare nuts at
the wide tube connections. Then cover up the tubing
connections with the flare insulator, and fill the gap at
the union with the supplied black insulation tape.
Finally, fasten the insulator at both ends with plastic
clamps. (Fig. 8-8)
Insulation material
The material used for insulation must have good
insuIation characteristics, be easy to use, be age
resistant, and must not easily absorb moisture.
After a tube has been insu-
CAUTION lated, never try to bend it
into a narrow curve because
it can cause the tube to
break or crack.
