4.0 MAINTENANCE
ICP-Series compressors require very little maintenance. To ensure optimum performance, the
following maintenance steps should be followed:
4.1 Compressor Lube Oil
4.1.1 Oil Level
Check the oil level on monthly basis. Under normal circumstances it should not be necessary to add oil
between oil changes. A significant drop in oil level means there is an oil leak. Please check the o-rings,
drain plug or oil sight glass.
Check the oil level only when the compressor is shut off. Replenish oil if it drops below bottom position of
the sight glass.
Caution: Do not add oil while the compressor is running, since hot oil can escape from the oil fill
port.
4.1.2 Oil Type and Quantity
See section 1.5 - Oil Filling - for details on oil type and quantity
4.1.3 Oil Change
Under normal ambient conditions with proper Gear Oil, it is recommended to change the oil every 10,000
operating hours. It is necessary to make the first oil change between 500 ~1000 operating hours.
Caution: If different brand oil is being filled, the old oil must be drained completely from the gear box.
4.2 Inline (Inlet) Filter
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced when
dirty. Consult service agent for replacement element information.
Caution: Depending on the mounting position of the filter, be careful not to allow accumulated
foreign material to fall in the pump suction inlet when removing the filter cartridge. Horizontal filter
installation is recommended to prevent this.
3.3 Operating Conditions
The ambient and suction air temperature must be between 5 and 40
°
C deg. The standard versions may
not be used in hazardous areas. Also it is recommended for operating personnel who is working near
compressor to wear ear protectors.
Caution: Any non compliance may lead to severe injury to persons and damage to the pump.
The pressure can be adjusted by turning knob of pressure regulating valve as marked on the top of valve.
The regulating valve or safety valve is set at permissible operating pressure and will be opened to
discharge the pressure if the compressor runs over the setting pressure for a safety operation.
Caution: Do not run the compressor without regulating valve or safety valve. Do not set the regulating
valve or safety valve at over permissible pressure. The compressor may be damaged severely.
4.3 Maintenance Chart
Weekly:
Check inline inlet filter element / Mesh. More often if high particulates in inlet stream
Monthly:
Check the oil level, Protective Mesh.
Semi-Annually:
Check cooling fans and coupling
Annually:
Check
Bearings / Shaft Seals, More frequently if operated at ambient temperature
exceeding 20°C
Every 5,000 operating hours:
Check the gear oil conditions, and if necessary, change the oils.
