Safety Warnings

Halogenated Hydrocarbon Fluid Hazard

NEVER USE halogenated hydrocarbon solvents or fluids containing such solvents

in this equipment. Examples of halogenated hydrocarbon solvents are: 1,1,1
trichloroethane, methylene chloride, fluids with the prefix “fluoro-“, “chloro-“,
“bromo-“ or “iodo-“, etc. These solvents can cause an explosion when used with
aluminum components in a pressurized fluid pumping system. The resulting
explosion may cause death, serious bodily injury or substantial property damage.

Pressurized Equipment Hazard

High pressure fluid can cause serious injury. This equipment is for professional use
only. Observe all warnings. Read and understand all applicable instruction manuals
before placing equipment into service.

Equipment Misuse Hazard

GENERAL SAFETY – Any use of the reservoir and related accessories not consistent

with that described in this manual, such as modifying or removing parts, over-pres­surizing, using incompatible fluids and chemicals, or using worn, damaged or incom­patible parts can cause them to rupture resulting in serious bodily injury, including
fluid splashed in the eyes or on the skin, or fire, explosion or other property damage.

NEVER alter or modify any part of this equipment, as doing so may cause it to
malfunction.

CHECK all reservoir components regularly and replace any worn or damaged parts
with only EFD supplied or approved parts. BE SURE that all dispensing equipment
and accessories are rated to withstand the maximum operating pressure of the
reservoir.

Personal Protective Equipment

Wear all protective eyewear, gloves, clothing and respirator as recommended by
the manufacturer of the fluid used.

4 Safety Warnings

System Pressure

NEVER exceed the maximum reservoir pressure of 6.9 bar gauge (100 psi). The

maximum supply pressure to the reservoir regulator must not exceed 10.4 bar
gauge (150 psi).

BE SURE that all dispensing equipment and accessories are rated to withstand the
maximum operating pressure of the reservoir.

If an EFD five-micron filter regulator #2000F755 is not used, be certain your plant
air is properly filtered and dry. Oil or particulate in the air supply line can cause
erratic performance and can contaminate the fluid to be dispensed if it is not prop­erly filtered.

Fluid Compatibility

BE SURE that all fluids, including their vapors, contained in the reservoir are com-

patible with all materials on the wetted materials list on page 14 of this manual.
Read the fluid manufacturer’s literature, including the MSDS (Material Safety Data
Sheet) and observe all warnings before pouring the fluid into the reservoir.

Fill Level

DO NOT overfill the reservoir. The recommended maximum fill level is 38.1 mm

(1.5") below the top of the liner.

Tipping and Dropping Hazard

BE SURE that the reservoir is placed on a hard, level surface and that all tubing

lengths are of sufficient length to allow free motion of all movable components
attached to the reservoir. DO NOT pull on tubing to move the reservoir.

Tipping the reservoir or otherwise supporting it on its side can cause fluid to enter
both the pressure regulator and pressure relief valve and interfere with their normal
function. A damaged pressure regulator and/or damaged pressure relief valve
may lead to an over-pressure condition within the reservoir. If the reservoir tips
or the pressure regulator and/or pressure relief valve otherwise become blocked,
they must be replaced with EFD supplied or approved parts before returning to
service.

Dropping the reservoir from any height can damage the pressure regulator, pressure
relief valve, and fittings and/or compromise the integrity of the reservoir body and
cover. A damaged pressure regulator and/or damaged pressure relief valve

may lead to an over-pressure condition within the reservoir. A damaged
reservoir body and/or cover can be an explosion hazard. If the reservoir falls

from any height, it must be thoroughly inspected for cracks or damage to the pres­sure regulator and/or pressure relief valve. If damage to a component is suspected,
it must be replaced with EFD supplied or approved parts before returning to service.

Safety Warnings 5

Tubing Safety

Pressurized tubing can be very dangerous. Tubing whose integrity is compromised
due to any kind of wear, damage or misuse can develop a leak, spraying the con­tents of the tank at high pressure. This spray can enter the eyes or cover the skin or
cause other serious bodily injury, fire or property damage.

Before pressurizing the reservoir:

1. BE SUREall fluid connections to the reser voir are properly secured.

2. Examine all tubing for cuts, wear, bulges and leaks. If any of these conditions
exist, replace the tubing immediately with EFD supplied or approved tubing.
Do not try to repair a damaged tube.

3. BE SUREthat the fluid to be dispensed is compatible with the tubing. Contact
the fluid manufacturer and confirm that the fluid is compatible with the tubing
material specified on page 15 of this manual.

4. BE SUREthat the tubing will not be exposed to
operating temperatures in excess of 50 °C (122 °F) or below 0 °C (32 °F) in
the application.
