On Filter Maintenance Tips Maintenance consists of replacing the canister (element) when it is fully loaded with contaminant. This is best determined by specifying the optional gage or pressure/vacuum switch. Replace the canister when the gage pointer is in the red zone, or when the switch activates the panel lamp. If an indicator is not used, replace canister after first 50 hours of operation, and every 250 hours thereafter. More frequent replacement could be required depending on operating conditions. Canister left in service too long may damage components. Canister Replacement Method: 1. Shut down the system and relieve pressure in the filter line. 2. Unthread canister and remove. This may require a strap wrench. 3. Apply a thin film of oil to the new canister seal. 4. Install the new canister. Tighten only hand tight. 5. Start the system and check for leaks. If oil seepage is noted, apply additional hand torque to the canister until seepage stops. (Keep canister and hands oil free to provide proper torque.) 6. Dispose of properly. 3-35
