Setup and Installation
Proper installation is crucial for the filter's performance and safety. Refer to your fuel dispenser's manual for specific instructions regarding filter housing access and fuel line depressurization.
- Prepare the Area: Ensure the fuel dispenser is off and the system is depressurized. Place absorbent materials to catch any spilled fuel.
- Remove Old Filter: Carefully unscrew the old filter from its housing. Be prepared for residual fuel to drain.
- Inspect Housing: Clean the filter housing and inspect the sealing surface for any debris or damage.
- Lubricate Gasket: Apply a thin film of clean fuel or appropriate lubricant to the new filter's gasket. This ensures a proper seal.
- Install New Filter: Screw the new Cim-Tek 70020 800-30 filter onto the housing by hand until the gasket contacts the sealing surface.
- Tighten Filter: Tighten the filter an additional 3/4 to 1 full turn after gasket contact, or as specified by the dispenser manufacturer. Do not overtighten.
- Check for Leaks: Restore fuel pressure and carefully check for any leaks around the filter seal. Address any leaks immediately.
Operation
Once installed, the Cim-Tek 70020 800-30 filter operates automatically as fuel flows through the dispenser. It continuously removes harmful particulates, ensuring clean fuel delivery to vehicles or equipment. No user intervention is required during normal operation.
Maintenance
Regular replacement of the fuel filter is essential to maintain fuel quality and dispenser performance. The replacement interval depends on fuel quality, volume dispensed, and environmental conditions.
- Replacement Schedule: Consult your fuel dispenser manufacturer's recommendations for filter replacement intervals. A common practice is to replace filters every 3 to 6 months, or after a certain volume of fuel has been dispensed (e.g., 50,000 gallons), whichever comes first.
- Signs of Clogging: Reduced fuel flow rate, increased pump noise, or difficulty in dispensing fuel can indicate a clogged filter requiring immediate replacement.
Filter Replacement Procedure: Follow the "Setup and Installation" steps in reverse for removal, and then proceed with the installation of a new filter.
