12.3.5 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.
12.3.6 Disposal of Outdoor Unit Drain Water
If a drain elbow is used, the unit should be placed on a stand which is taller than 3 cm.
If the unit is used in an area where temperature falls below 0°C for 2 or 3 days in succession, it is recommended
not to use a drain elbow, for the drain water freezes and the fan will not rotate.

Operate the unit at cooling/heating operation mode for fifteen minutes or more.
Measure the temperature of the intake and discharge air.
Ensure the difference between the intake temperature and the discharge is more than 8°C during Cooling
operation or more than 14°C during Heating operation.
