Compressor, air/oil sump and all piping and tubing may be at high temperature
during and after operation.
Do not attempt inspection or cleaning of air-cooled heat exchangers until
cooling fan has stopped rotating. Disconnect lockout and tag out package from
power supply.
Air-cooled heat exchanger cores are fabricated from aluminum. Do not use
caustic liquids to cleanse core or permanent damage will take place.
1. Be sure the unit is completely off and that oil reservoir is depressurized.
2. Open and/or remove enclosure door panel adjacent the cooler assembly, see Figure 6-2 for details.
3. Inspect core area. If blocked with debris, use a moderate (e.g., 100 psi) source of compressed air
while directing nozzle (pointed to outer core finned surface) to dislodge debris and clean. Vacuum
(applied from inner finned core surface) can also be employed to clean the surfaces.
4. Remove all loose debris from inner surfaces of the enclosure, including the main cooling fan area and
its pre-filter, after cleaning process is complete.
5.
Re-install the removed enclosure door panels.
