Installing/Changing a Fluid Syringe
Installing a Syringe of Conditioning Fluid (Solder Paste Applications Only)
When using the DV-7000/DV-8000 valve to dispense solder paste, you should install a syringe of
conditioning fluid and prime the pump in between cleanings. See "
Solder Paste Applications
" later in this
section. You may leave the conditioning fluid installed, until you are ready to install the syringe of solder
paste.
WARNING!
Refer to the Material Safety Data Sheet (MSDS) for information on safety, handling,
and disposal for all fluids and materials before use. All fluids and materials must be
disposed of according to local regulations. Wear personal protective equipment
(PPE) when performing this procedure to prevent contact with caustic chemicals.
CAUTION!
Only trained service technicians should perform this procedure.
Tools and Materials Needed
•
Syringe of Conditioning Fluid
•
Personal Protective Equipment
•
Syringe Receiver Head and Air Hose
•
Feed Tube and Fittings
1. Install the fittings and the feed tube on the pump as required by your application (Figure 4-6).
!
For most applications using the DV-7000, a flexible feed tube attaches to one barbed fitting
threaded into the syringe bracket and another threaded into the dispensing cartridge.
!
For line and pattern applications using the optional configuration DV-7000, a rigid feed tube
assembly threads into the syringe at one end (using a threaded Luer fitting) and the cartridge
fitting at the other end. The syringe bracket is not installed.
!
For applications using the DV-8000, a rigid feed tube assembly threads into the syringe at
one end (using a threaded Luer fitting) and the cartridge fitting at the other end.
2. Obtain a syringe containing conditioning fluid and remove the cap from the end.
3. Slide the syringe down through the syringe clip and screw it into the syringe fitting.
4. Screw a clean receiver head onto the top of the syringe.
5. Connect the syringe air hose to the receiver head and the blue
FLUID AIR
connector on the
dispensing head bulkhead.
6. Perform a dispensing system start-up as specified in the applicable dispensing system manual.
7. Prime the pump. See “
