Daikin Oil Cooling Unit AKZ149

Oil pollution at NAS10 or lower level?

Normal oil level in the oil tank?

Main machine oil piping not blocked (fully closed)?

Power supply voltage within range?

Compressor, fan and oil pump do not abnormally sound during operation?

Sheath of the OILCON power lead not broken?

• Check whether there are any substances in the condenser by removing the air filter (You do not need to remove the external plate).

• If the condenser becomes extremely dirty, clean it with a brush, air blower, etc.

* When cleaning the condenser fins, wear gloves. Otherwise, you may be injured by the sharp edges.

• However, do not use water or cleaning agents for cleaning. The fan motor or pump motor may cause an earth leakage.

• Wipe the exterior surface with a dry cloth. Never splash water over it.

• To clean the exterior, do not use a brush, polish powder, acid, solvent (benzine etc.) or hot water. Using such substances causes the paint to peel off.

NOTE: Wear gloves when working as the fins of the condenser may cause injury while replacing the air filter.

Check if the air filter is clogged with dust.

If the air filter is clogged, the wind volume reduces, resulting in capacity deterioration. Also, the compressor’s protection device is activated, hindering smooth operation. Furthermore, it causes power consumption increase.

Operating the unit without the air filter causes a fault.

Check if the air filter is removed properly.

NOTE! If the air filter is clogged, the cooling capacity deteriorates, resulting in excess power consumption. Clean the air filter periodically to save power consumption.

Check if the air filter is cleaned properly.

Sign off on the air filter maintenance

• Clean the suction strainer every six months.

• Clean to prevent the pump flow rate from being reduced by dust clogging.

• Clean to prevent abnormal sound caused by cavitation.

• Inspect the bottom of OILCON (drain pan) every six months and if the oil is accumulated, discharge it from the oil drain port.

• The tightening torque of the hexagonal bolt for the drain is 2N·m.

• If it is tightened with excessive torque, the bottom frame may be damaged.
