Special Notes

1. A water probe option is available.

2. Allow at least 2 inches (51 mm) clearance under the units for draining water.

3. Allow at least 5 inches (127mm) clearance above the units for element replacement.

4. Maximum allowable pressure for all models is 50 PSI / 345 kPa.

5 These units comply with ASTM Specification F1201--88 which is accepted by the USCG for inspected vessels.

Note: ’75’ models do not have the option for both filters to be on--line at the same time.

General: Our heavy-duty Series MC Marine Fuel Filter/Water Separators protect engines from water, dirt, foulants and other contaminants with superb efficiency and filter life. The primary 10 or 30 micron fuel filters last by as much as 1000 hours with average fuel quality.  The units are designed for installation on the suction (vacuum) side of the fuel transfer pump for best efficiency.  The Series MC filters are normally installed as your primary filtration. Do not remove the engine secondary or final filter if one is present. 

Compliance and Certification for Marine Use:  All Series MC units meet 33 CFR (Code of Federal Regulations) Part 183, subpart J (pleasure craft) and 46 CFR, Part 56.50--75 (commercial shipping) for diesel fuel systems. Additionally, Series MC units meet or exceed A.S.T.M. Specification F--1201--88 which has been adopted by the United States Coast Guard for inspected vessels. The unit label is ASTM formatted for identification and individual model certification is available upon request.

Filters: High--capacity replaceable cartridge elements stop water and remove solid contamination and are available in 2, 10 or 30 micron. Equipment owners can specify their filtration needs based on application, fuel quality, operating climates and maintenance schedules. A 30 micron filter (or primary filter) is used to filter raw fuel (or poor quality fuel) before it can be further filtered by finer medias such as a 10 or 2 micron.  A 10 micron filter (or primary/secondary filter) is used to filter fuel which is known to be of good quality.  A final filter, such as a 2micron filter is the finest filtration available and should be the last filter in the fuel delivery system before the fuel is ingested by the engine.  A simple rule to remember is the finer the filtration, the more frequent the filter change. (Carry extra filters with your equipment).

Water Collection:  The Series MC collection sump stores water and contaminants until it is drained by the operator. All units feature a rugged, 1/4 turn drain valve for easy service.

Optional Water Probe Available for Diesel fuel systems only. All units may be ordered with a water probe to alert the operator of a high--water condition, even while the equipment is operating. The unit is then drained of water at the earliest convenience.  Note: The RK30880 Water Probe features built--in electronics to detect the presence of water. An indicator lamp is supplied for in or under dash mounting.
