Low point drain |
After line displacement, flush min of 2 gallons at each low point |
|
Hydrant system maintenance flushing |
Hydrant system mainline SHOULD be flushed on a 5 year frequency |
|
Filter/water separators (truck) |
All new Shall meet EI 1596; qualified to EI 1581 by test or EI 1581 by similarity as per EI 1582. If qualified by similarity, a similarity data sheet shall be maintained and data plate reflecting such qualification |
|
Filter water separator shall also be equipped with: |
Automatic water defense (shall include operational test); placard indicating visual inspection and element change |
|
Filter coalescer/separate elements shall be replaced |
Differential pressure exceeds 15 psi or there is a sudden drop in pressure; filter.membrane test indicated last element is not performing; continuous sump samples indicate surfactants, microbial, solid contaminants; 36 month service life has expired; free water detection test indicates elements are not performing |
|
Filter monitors |
Shall meet EI 1583 7th edition |
|
Filter monitor in addition to section 2.8.2 requirements must also |
Have pressure limiting device that will shut down flow if 15 psi is reached; restrictions on reset procedures in the event of a shutdown; ability to perform periodically testing of differential pressure limiting switch |
|
Filter monitors must be replaced |
12 months service life has expired;differential pressure exceeds 15 psi or there is a sudden drop on pressure; chemical water detection test (EI 1598) qualified electronic water sensor indicates a positive reading of more than 30 ppm |
|
Dirt defense filters shall meet EI |
EI 1599 |
|
Electronic water sensors EI 1598 and auto. Water defense system |
Automatic water defense system is designed to detect bulk water. Electronic water sensor is designed to detect free water and return a measurement of the free water in fuel. Ei 1598 type sensor cannot be used to meet requirements for an automatic water defense system 2.8.2.3.2 |
|
Programmable logic controller (PLC) shall be programmed to |
Shut down flow of fuel if the water is 20 ppm or greater for 10 seconds, 50 ppm + for 5 seconds, control the indicator light |
|
Water barrier filters EI |
1588 |
|
Primary pressure controls |
Intended to protect the aircraft under conditions of constant flow and also from pressure surge caused during aircraft valve closure. |
|
Secondary pressure |
Intended to protect the aircraft in the event of primary pressure control failure |
|
Fuel pressure control systems may utilize |
1. Pressure controlling hydrant pit valves 2. Pressure controlling hydrant pit couplers 3. In line pressure control valves 4. Hose end pressure control valves (HEPCV) 5. Pressure switches that will cause rapid shutoff of the fuel flow in the event of high fueling pressure |
|
Deadman shall completely stop fuel flow within |
5% of the fuel flow rate at the time of release (if actual fuel flow is 500 gpm total overrun must not exceed 25 gallons (5% of actual flow rate)) |
|
Hoses and couplings shall meet |
EI 1529 grade 2 type c; or EI 1529 grade 2 type CT |
|
