■ Check the condensate drain
Moisture in the intake air, especially in hot and humid environments, is condensed inside the air compressor during
compression. Daily inspect intercooler/aftercooler condensate drain to verify that there is a discharge of compressed
air (with condensate) when the air compressor is loaded. Bi-annually, clean the strainer element and annually clean the
orifice for both intercooler/aftercooler.
■ Cleaning of strainer element
The strainers for both the intercooler and aftercooler
shall be cleaned.
① Discharge the compressed air in the procedure in 9.4
.
② Remove the cover of the strainer.
③ Remove the element, wash with water and blow air.
④ Remove the element from inside the strainer and
wash with water.
⑤ Replace the cleaned element in its original position
and set the O-ring or gasket, and plug properly.
◆ Cleaning of strainer
■ Cleaning of orifice
Inspect and clean the orifices annually. Be sure to
stop the air compressor before inspecting and/or
cleaning the orifices.
■ Replacement of the strainer and solenoid
valve
Replace the solenoid valve and the strainer every 2
years (if operating 8000 hours/year) or 3 years (if
operating 4000 hours/ year) to new whole assembled
parts.

CAUTION
● Verify that there is discharged air with
condensate is discharged through the drain
ports of intercooler and aftercooler every
45seconds for 45/55 kW model and every 30
seconds for 75 kW model during loading.
● If compressed air is not discharged, clean
and unclog the drain port (filter & orifice).
● Operating the air compressor without
draining the condensate from the
intercooler/afterooler, may rust the airend
internally and cause a major failure.
