horizontal position.
2 Remove the 2 caps (1.0 ~ 2.0HP) or 3 caps

3 (1.0 ~ 2.0HP) or 4 (2.5HP) mounting screws.

12.3.7 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.
12.3.8 Check the Drainage

Open front panel and remove air filters. (Drainage
checking can be carried out without removing the
front grille.)

Pour a glass of water into the drain tray-styrofoam.

Ensure that water flows out from drain hose of the
indoor unit.
12.3.9 Evaluation of the Performance

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.
