Insulation of Refrigerant Tubing
To prevent heat loss and wet floors due to dripping of
condensation water, both the wide and narrow tubes
must be well insulated with proper insulation
material. The thickness of the insulation should be a min.
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.
