Fueltec’s Fuel Polishing = water and parculate removal
Fuel is relavely clean when it leaves the renery, as it’s transported downstream it can
easily become contaminated with water, rust, silica, and bacteria. As a result the fuel
falls below the engine manufacturers recommended cleanliness levels. Fuel in storage
becomes even more contaminated with bacterial and fungi growth.
Fueltec’s fuel polishing systems rst stage primary bag lters remove parculates down
to one micron; the second stage lter/coalescer removes more parculates with an
inside to outside ow then coalesces ny water droplets into larger drops which stream
to the systems water trap. The third stage water separator prevents the water from
owing with the fuel with a Teon barrier. This is the same process and technology that
is used extensively on the puricaon of military and domesc jet fuel.

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 (7–1–10
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.

WATER SEPARATOR AIR BLEED
The Model CF50E is equipped with an automatic and manual air bleed valves.
CAUTION: It is required that all air is removed from the water
separator housing for safe efficient operation.
Whenever the water separator function is used:
1. First open the manual air bleed valve which is located on the top cover of the water
separator housing.
2. Place 3-way fluid flow selector valve handle in a vertical position as shown on page
9 of this manual. This will direct fluid from the pump to the water separator
housing.
3. Clear the work area for a 50’ radius around the system before starting the pump.
4. When the pump is started you will hear air escaping from the manual air bleed
valve. USE EXTREAM CAUTION as this air may contain explosive fumes from
contact with fuel.
5. When air stops escaping from the manual air bleed valve, close the valve.

CF50E Settings for Underground Storage Tanks
When separating water from fuel in underground fuel storage tanks always position the
return to tank valve so the pump pressure gauge reads a min. of 10 PSI.
This pressurizes the water separator housing so you can drain the separated water
without stopping the operation.
After starting the pump, rotate return to tank valve handle upward until the pump
pressure gauge reads 10 PSI.

FUEL TANK SAFETY
• Purge fuel tank (fill airspace inside the tank between any fuel and the top of
the tank) with argon or CO2 prior to drilling or sawing holes that penetrate the
tank to minimize the risk of explosion.
• Maintain a purged condition while installing fittings on a fuel tank.
STATIC GROUND
• Always attach a static discharge cable from the Fueltec System to the fuel
tank being serviced.
The flowing movement of flammable liquids inside a pipe can build up static electricity.
Non-polar liquids such as gasoline, diesel, kerosene and light crude oils exhibit signifi-
cant ability for charge accumulation and charge retention during high velocity flow.
Static electricity can discharge into a fuel vapor. When the electrostatic discharge en-
ergy is high enough, it can ignite a fuel vapor and air mixture. Different fuels have dif-
ferent flammable limits and require different levels of electrostatic discharge energy to
ignite.
. The use of a static discharge cable can help to prevent or safely dissipate the build
up of static electricity.
