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.
