11.1.6 Piping Insulation
1. Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation
Diagram. Please wrap the insulated piping end to prevent water from going inside the piping.
2. If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by
using POLY-E FOAM with thickness 6 mm or above.
Refrigerant tubing shall be protected against mechanical damage.
CAUTION
Use a material with good heat-resistant properties as the heat insulation for
the pipes. Be sure to insulate both the gas-side and liquid-side pipes. If the
pipes are not adequately insulated, condensation or water leakages may
occur.
