Safety Warnings
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 system 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 a respirator as recommended by the manufacturer of
the fluid used.
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 6 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.
User’s Responsibility
It is the responsibility of the user to ensure the 781RC system is installed in a manner that complies with
all local and national jurisdictional requirements.

Safety Warnings (continued)
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 the system
to run dry, resulting in possible pump damage.
If any system component parts are damaged or worn, they must be replaced with EFD supplied or
approved parts before returning them 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 and pump 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 polyethelene tubing supplied.*
*Use only Nordson EFD supplied polyethylene tubing for applications that use solvent-based liquids.

Preventive Maintenance
As part of maintaining continuous trouble-free use of this product, EFD recommends a few very simple
preventative maintenance checks.
1. Periodically inspect tube-to-fitting connections for proper fit. Secure as necessary.
2. Check tubing for cracks and contamination. Replace tubing as necessary.
3. Check all wiring connections for looseness. Tighten as necessary.
4. If front panel of 8040 controller requires cleaning, use a clean, soft damp rag with a mild detergent
cleaner. DO NOT USE strong solvents (acetone, MEK, etc.) as they will damage the front panel
material.
5. Dry running time should be kept to a minimum — less than 5 minutes.
6. During initial pump startup and priming, pump speed should be kept low until fluid reaches the
pump. Once primed, pump speed can be increased.
Turn off pump enclosure assembly before servicing any 781RC recirculating system components.
