Important Disposable Component Safety Information
All Nordson EFD disposable components, including syringe barrels, cartridges, pistons, tip caps, end caps,
and dispense tips, are precision engineered for one-time use. Attempting to clean and re-use components will
compromise dispensing accuracy and may increase the risk of personal injury.
Always wear appropriate protective equipment and clothing suitable for your dispensing application and adhere to
the following guidelines:
• Do not heat syringe barrels or cartridges to a temperature greater than 38° C (100° F).
• Dispose of components according to local regulations after one-time use.
• Do not clean components with strong solvents (MEK, acetone, THF, etc.).
• Clean cartridge retainer systems and barrel loaders with mild detergents only.
• To prevent fluid waste, use Nordson EFD SmoothFlow
™
pistons.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut off the system immediately and perform the following
steps:
1. Disconnect and lock out system electrical power. If using hydraulic and pneumatic shutoff valves, close and
relieve pressure.
2. For Nordson EFD air-powered dispensers, remove the syringe barrel from the adapter assembly. For Nordson
EFD electro-mechanical dispensers, slowly unscrew the barrel retainer and remove the barrel from the actuator.
3. Identify the reason for the malfunction and correct it before restarting the system.
Disposal
Dispose of equipment and materials used in operation and servicing according to local codes.

Equipment-Specific Safety Information
The following safety information is specific to the Liquidyn P-Jet SolderPlus valve.
Do not dry cycle the valve! The valve be damaged if it is operated without fluid, causing leakage and a poor seal.
Precise dispensing can no longer be guaranteed if this occurs.
CAUTION
General
• Before use, read the complete operating instructions and all safety instructions to ensure safe and correct usage.
• Observe all safety instructions.
Intended Use
• The micro-dispensing system is for indoor use only.
• Do not use the micro-dispensing system in an explosive atmosphere or with explosive materials.
Fluid Compatibility
• Use only for the micro-dispensing of low- to medium-viscosity fluids or pastes.
• Ensure that all fluid carrying parts and sealings are resistant to the dispensing material used.
Operating Conditions
• Operate heaters (optional) within the approved temperature range only. Refer to “Specifications” on page12.
• Use only heaters that are distributed by Nordson EFD specifically for this micro-dispensing valve.
• Adhere to the maintenance intervals specified under “Service” on page30.
• Do not subject the valve needle to force, knocks, or impact.
• Avoid long shutdown periods with the system switched on.
• Do not operate the valve in a dry condition (without dispensing material).
