SECTION 14
MAINTENANCE SCHEDULE
SERVICE CHECK LIST
Daily Checks:
·
Air Filters (Compressor)
- Replace when controller displays
“CHANGE AIR FILTER” message. Refer to
Section 7, page 63 for air filter details.
·
Oil Separator Element
- Replace when controller displays
“CHANGE OIL SEPARATOR ELEMENT”.
Refer to Section 5, page 46 for oil separator element details.
·
Air/Oil Reservoir Oil Level
- Check the reservoir oil level during compressor operation only - add oil if
required. Refer to Section 5, page 46 for full details. DO NOT MIX LUBRICANTS.
·
Start/Modulation/Stop Operation
– Verify that compressors maintain steady compressed air pressure.
·
AirSmart Operational Parameters
– Maintaining a periodic log of package critical parameters (e.g.,
pressures, temperatures, speeds, load levels, etc) helps identify when abnormal operation occurs.
·
AirSmart Controller Messages and Alarms
– Acknowledge the presence of an abnormal condition and
take action to correct it.
Weekly Checks:
·
Heat Exchangers (air-cooled)
- Check for dirt accumulation on (air-cooled) air/oil heat exchanger finned
surfaces. Refer to Section 6, page 56 for detailed instructions to clean heat exchanger surfaces.
·
Axial cooling fans
– Check for grime and dirt build-up on fan blade surfaces. Refer to
Section 6 for detailed instructions to clean axial cooling fan blade surfaces
·
Air Filters (Electrical Box)
– Check filter elements for dirt accumulation. Refer to Section 7, page 63 for
detailed instruction to clean filter elements.
Every 1000 Hours:
·
Oil Filter
- Replace.
·
Oil
- Sample and analyze.
Every 3000 Hours:
·
Motor Lubrication –
Inspect motors for abnormal noise and vibration. Grease-lubricate per guidelines
included in Section 13, page 80 of this manual.
Every 8000 Hours (Or as Prescribed by Oil Analysis Results):
Compressor Lubricant –
Replace.
Yearly Checks
:
·
Heat Exchangers (air and water cooled)
– Check cooling performance of air and oil cores – see Section
6, page 56 of this manual for details on typical performance expectations as well as recommended
cleaning procedures.
·
Pressure Relief Valve –
Check operation of device
– see Section 11, page 77 for test procedure.
