Respect the installation clearance. FDYM30CV1M Do not put the indoor unit where there is direct sunlight on unit. FDYB30CV1M The location is suitable for piping and drainage and it must be FDYM40CV1M have a large distance between a door and unit.
As a result, compressor reliability will be affected. Always choose the shortest path and follow the recommendation as tabulated below: Model FDYM30CV1M FDYM40CV1M FDYM60CV1M FDYM71CV1M FDYM80CV1M Data FDYB30CV1M FDYB40CV1M FDYB60CV1M FDYB71CV1M Maximum Length, A m (ft) 12 (39.4) 12 (39.4) 15 (49.2) 15 (49.2) 15 (49.2)

SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH SCROLL COMPRESSORS These precautions are intended for use with Scroll compressors only with R22, R407C, R134A, R404A, R507 and R410A refriger- ants but are not applied to other compressors. Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant in the system or if refrigerant is added too slowly.
OVERALL CHECKING Ensure the following, in particular:- 2. Watch out for the following:- 1. The unit is mounted solidly and rigid in position. Is the electric plug firmly inserted into the socket? 2. Piping and connections are leak proof after charging. Is there any abnormal sound from unit? 3.
AUTO RANDOM RE-START FUNCTION If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is restored. (Applicable only to units with this feature). SERVICE AND MAINTENANCE Service Parts Maintenance Procedures Period Indoor Air Filter...
TROUBLESHOOTING When any malfunction of the air conditioner unit is noted, immediately switch off the power supply to the unit. Check the following fault conditions and causes for some simple troubleshooting tips. Fault Causes 1. The compressor does not start operate after 3 minutes - Protection against frequent starting.
