Assembling the HV-2100 Jet
The HV-2100 jet is shipped fully assembled except for the diaphragm and nozzle plate.
A specific diaphragm material and nozzle plate orifice diameter should be chosen based
on the application and dispensing fluid. The steps required to correctly assemble the
diaphragm and nozzle plate on the jet body are detailed below.
Before assembling the jet, make the necessary pneumatic and electrical connections as
described in Sections 2.2 and 2.3.
3.1
Jet Assembly Overview
Figure 3-1 below shows the alignment of the heater block, diaphragm, O-ring, and
nozzle plate.
There is a grooved pattern on the bottom face of the heater block that matches
the raised embossments on the diaphragm. The grooves position the diaphragm
correctly on the heater block.
The diaphragm also has a metal insert with a post that must be inserted into the
central hole on the heater block.
Although a diaphragm can be inserted without the jet connected to an air source,
it will not sit flat on the heater. It is recommended to OPEN the jet before
assembling the diaphragm. Detailed instructions are in Section 3.4 - Install the
Diaphragm and Nozzle Plate.
