Questions & Answers

1Is it easy to install?
YES. Simply locate a space on the bilge wall large enough to allow the removal of the housing to replace the filter.
1. Secure the bracket to the wall and the filter system head with the screws (included)
2. Purchase 2 straight connectors that are 1 1/2" NPT threaded on one end and barbed on the other. The barbed end needs to be the correct diameter to fit into your existing discharge hose.
3. Cut into the existing bilge pump discharge hose and secure one end to the "IN" and the other to the "OUT" ports on the filter head using the straight connectors. Be sure to connect the bilge pump end to the "IN" port of the filter head.
4. Install the alarm in the wheelhouse, running the wire the shortest distance available.
5. Connect the positive and negative wires to a power source (typically the same source that powers your bilge pump)
2Can the system be installed horizontally?
It will work horizontally but it will be difficult to keep the filter cartridge centred to screw the housing back on when changing the filter. In the vertical position, you will need at least 3" from the floor to the bottom of the housing so you can unscrew the housing and replace the filter.
3What ppm will the filter remove oil & fuel?
The legal limit in Canada for bilge water contamination is 15 ppm for coastal waterways and 5ppm for inland waterways. The filters will remove contamination to below 5 ppm
4If the filter gets blocked, does an alarm 'sound' or does it send a signal to a screen in the wheelhouse or an app on my phone?
There is a small bright amber light included with the filter system that should be installed in the wheelhouse. This light will come on if the filter becomes plugged. An app is being considered 'down the road' but this will take some time for software engineering development.
5What do I do when the warning light comes on and do I need to reset anything?
Simply turn off your pump and change the filter. There is nothing to reset.
6What is the box that is connected to the filter head?
It is a sensor that measure the air flow coming in and going out. The filter is designed not to plug but if it becomes blocked for any reason, the airflow pressure will be increased on the "IN" port which will trigger the warning light in the wheelhouse.
7What are the 2 small hoses connecting the head to the alarm sensor?
These hoses allow air in the line to flow into the differential pressure sensor to constantly measure the pressure. The pressure sensor 'senses' air pressure as the water passes by the small brass elbows, so water doesn't actually flow through the small electronic box (just air), and water constantly flows through the filter. It is also a "full flow filter" so even when it has reached its maximum hydrocarbon capacity, it will still allow water to flow through, but the water is no longer being cleaned.
8How long will a filter last?
Depending on the system, the filter will capture oil and fuel at capacities of approximately 1 Litre (System 2) or 2 Liters (System 3). Filter life depends on the level of contamination in the bilge. Although there are bilges with extremely high levels of contamination (1000's of ppm), the average bilge has about 150 ppm and in those situations, a filter can last 4-6 months of continuous usage.
9Is there anything I should do to prepare my bilge for the filter system?
1. Clean all visible contamination with absorbent pads. The filters are designed to capture trace amounts of oil and fuel, not to clean up a spill.
2. Ensure all engine fuel and oil leaks are repaired before installing the filter system
10Is there a bypass in the event of an emergency?
There is no bypass. The filter is designed in such a way that even when it's at capacity (full of oil, fuel, etc.), it will still pump out at approximately 90% of the original flow rate. However, it will be pumping out water and hydrocarbons at this point.
11How much wall space to I need for installation?
The BFS-2 (System 2) requires 23" high x 10" wide space and the BFS-3 (System 3) requires 33" high x 10" wide space
12What if my boat has more than one pump?
The bilge water filter should be placed in line with the electric pump and not the mechanical pump.
13Where do I purchase the replacement filters? Are they available locally?
Currently, the replacement filters can be purchased directly from GreenOil.
