IMPORTANT
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. 8mm.
CAUTION
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.
