Insulation of Regrigerant 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. 8 mm.
After a tube has been
insulated, never try to bend
it into a narrow curve
because it can casue the
tube to break or crack.
