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