Insulation of Refrigerant Tubing
Because capillary tubing is used in the outdoor unit, both the
wide and narrow tubes of this air conditioner become cold. To
prevent heat loss and wet floors due to dripping of
condensation, both tubes must be well insulated with a
proper insulation material. The thickness of the insulation
should be a min. 5/16"(8 mm).
After a tube has been insulated,
never try to bend it into a narrow
curve because it can cause the tube
to break or crack.
