Prime the Jet
Note: HV-2100C Controller shown for illustrative purposes.
1.
Prior to dispensing, it is necessary to prime the jet in order to purge residual air
from the system. In order to do this, the fluid must be brought to dispensing
temperature.
From the HV-2100C front panel, use the following procedure to turn on the
heater.
Press
(INDEX) until Run-Stop (r-S)
is displayed on the Present Value (PV)
line.
Use the
arrows to select the
rUn
setting on the Set Value (SV) line.
Press
(
ENTER) to save the change.
Heater is ON.
Press
again to return to the main screen
Use the
arrows to change Set Value (SV) to the dispensing temperature for
the fluid being used.
Wait ten minutes for the temperature of the nozzle to be stable.
2.
Position a purge cup under the jet nozzle.
3.
Turn the
Fluid
Air
OFF (“
O
” on
Air
switch).
4.
On the controller touch panel:
Tap on
Fluid Pressure
and set to
0
.
Tap on
Jet
to OPEN.
5.
Turn the
Fluid
Air
ON (“
I
” on
Air
switch).
6.
Keep the purge cup positioned under the
nozzle. While watching for fluid flow from the
nozzle, increase
Fluid Pressure
in small
increments.
Once fluid begins to slowly flow, continue at that pressure until there are no
bubbles in the fluid.
7.
Tap on
Jet
to CLOSE.
8.
Tap on
Jet Pressure
and set to 45 psi.
9.
It is useful to designate a recipe on the HV-2100C controller for the priming
process. Use these parameters:
Refill = 10.0 ms
Dwell = 10.0 ms
= 0.3 ms
Drops = 250
This recipe allows most fluids to flow through the jet easily.
