Insulation of Refrigerant Tubing

IMPORTANT

To prevent heat loss and wet floors due to dripping

of condensation, both the wide and narrow tubes must be well insulated with a proper insulation

material. The thickness of the insulation should be a min. 5/16 in.

After a tube has been CAUTION insulated, never try to bend it

into a narrow curve because it can casue the tube to break or crack.

Thickness:

Min. 5/16 in.
