PROBLEM ACTION
FAULT ANALYSIS
1.- Unit not operating.
Check power is available at unit.
Check wiring.
Check remote control is functioning and set properly (if any).
2.- Indoor unit fan running too
fast without apparent
speed change.
Check the indoor unit filter is clean.
Check wiring.
If problem persists then motor may be faulty.
3.- Condensate overflowing.
Check drip tray for blockage, and condensate drains away.
Check unit is level.
Check condensate pump is working.
Check service drain pipework.
AIR DISTRIBUTION
Louvre position for correct air flow in heating
mode.
Louvre position for correct air flow in cooling
mode.
DISASSEMBLING DRIP TRAY
Remove the air intake grille and filter.
Disassemble the diffuser panel by removing the screws that attach it to the unit.
Detach the volute/s by removing the screws, and the electrical panel cover/s.
The drip tray can be taken apart by removing its screws, as shown in the figure.
Louvres change position to distribute air according to heating or cooling
operation (only for plastic diffuser).
In cooling operation the louvres are positioned to distribute air
outwards from the discharge, which allow airflow close to the ceiling.
In heating mode the louvres are repositioned to blow air in a
downward direction. The air should flow towards to the floor to prevent
layers or stationary hot air forming in the upper part of the room.
When the electro-mechanical thermostat is used, the louvres movement
is manual, louvres should be positioned manually.
ACCESS TO INTERNAL COMPONENTS
When checking or replacing any internal component of the unit, e.g. coil, fan motor, condensate pump, float switch, the drip
tray and volute must be removed.
