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, over­pressurizing, 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.

Safety Warnings 3

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 compatible 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

Safety Warnings 5

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.

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 SURE all fluid connections to the reservoir 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 SURE that 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 SURE that 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.
