2017 Fueltec Model CF50E Fuel Polishing System
Model CF50E OPERATING PROCEDURE
The Model CF50E is designed for use on fuel storage tanks with a capacity
greater than 1,500 gallons. Use on tanks smaller than 1,500 gal. could cause
emulsification.
1.
Take a
DIESEL
fluid sample from the fuel tank
’
s bottom, (see page 24) to check for
water, sludge, rust, bacteria, fungi, or other particulates. Most contamination is heavi-
er than fuel and is normally found at the lowest 5%
-
10% of the storage tank.
2.
First read and understand fuel handling safety requirements: 29 CFR Ch. XVII
(7

10
Edition) and FLAMMABLE AND COMBUSTIBLE LIQUIDS (attached)
3.
Attach the
2”
x
25’
fluid supply hose to the primary filter manifold with cam and
groove fittings. Attach a fluid pickup tube to the opposite end of the hose, (page 11)
4.
For bulk water removal attach the
2”
x
25’
return to tank hose to the discharge port
nearest the diaphragm pump, (page 10).
5.
To separate water from
DIESEL
fuel to less than 100 parts per million attach the
2”
x
25’
return to tank hose to the water separator housing lower discharge port, (page 7.).
Attach the fluid discharge stinger to the tank end of the hose.
6.
Check to see that the bag filters are secured in the primary filter housings, (page 12.)
7.
Check to see that the five coalescers and two water separators are secured in the
water separator housing, (page 13.)
8.
Open air bleed on the top of the water separator housing, (page 6) when air stops
escaping, close the valve.
9.
BLANK
10.
Open all four primary filter inlet and discharge valves by turning handles to a vertical
position, (page 11)
11.
For filtration only or bulk water removal without the water separator, set 3
-
way valve
at diaphragm pump to discharge by rotating the handle to a horizontal position
12.
For both primary filtration and water separation, set the 3
-
way valve at the diaphragm
pump to a vertical position. (page 10)
13.
If the tank bottom water level is greater than three inches, pump the bulk water level
down to three inches with the CF50E set on filtration only, then set the system for wa-
ter separation, to remove water to less than 100 Parts Per Million.
14.
Start system
15.
As the water is being separated from the fuel, the level can be seen in real time in the
clear sight tube. (page 8.).
16.
Drain the water from the pressurized water trap by opening the drain valve, (page 8.)
The separated water can be drained with out stopping the operation; and with no loss
of fuel in the process.
17.
Primary filter bags can be changed without stopping the operation by closing the two
valves on one primary filter housing.
18.
To drain fluid from the system after use, stop system, close primary filter supply
valves, (page_) close all return to tank valves, open primary filter air bleed valves,
open water drain valve after placing discharge hose in a waste container.
Start system. Stop system when fluid discharge stops from water drain hose.
