bucket.

3. Remove screws holding the drain pan. Carefully hold the

drain pan to remove it from the assembly.

screws. Center and align the metal fan inlet orifice with

TROUBLESHOOTING

See Table 9 and Fig. 35 for troubleshooting information.

Fault Code — Once a failure occurs with the indoor unit in

operation, the green LED on the indoor unit flashes at intervals

of 0.5 seconds. The fault code is deduced from the number of

times the green LED flashes, blocking unit operation. Between

one flash cycle and the next one, a pause of 5 seconds elapses.

See Fig. 34.

USING THE EMERGENCY BUTTON — The Emergency

button is for use by a qualified service technician only. The

Emergency button is for use when the room controller is inop-

erative. Use a screwdriver to press the emergency button

through the metal protection grille. See Fig. 35.
