Leave the unit angled in this position for approximately 15 minutes. This will allow any air trapped in the
syringe to rise towards the distribution valve such that it can be ejected out.
9. Once the system runs free of air bubbles, clean the mold plates of any excess recoat material.

Automatic Injection System (PTR406)

The PTR406 comes with the automatic recoat injection pump fitted inside the unit. It is very important to remove all
air from this recoat injection system prior to performing a recoat. When operating the system for the first time, the
pump must be filled with recoat material and cleared of all air in the pump and tubing. In order to clear the inject
tube, recoat material must be injected out through the mold inject port and collected and disposed of. Make sure to
have cotton swabs and acetone or isopropyl alcohol available for this purpose prior to starting this procedure. The
Handset Controller is required to perform this procedure.

Prior to handling the UV acrylate material, be sure to read the Material Safety Data Sheet provided in
Chapter 14.2: Material Data Safety Sheet. Also review the MSDS provided with your chosen cleaning
To prime the recoat injection system:
1. Turn off power to the unit.
2. Remove the front plate by using the 3/32" Allen wrench provided in the tool kit to remove the four (4) black
socket-head cap screws located at the corners of the plate.
3. The recoat pump is located on the left side of the
device as shown in Figure 34. Unscrew the brown
recoat bottle located at the front of the pump and
remove by angling out through the front opening.
The red Fill Tube will flex to allow removal.
4. For new systems, replace the empty recoat bottle
shipped with the unit with a new bottle of recoat
material. For systems that have previously been
run with recoat material, the recoat injection
system should be flushed clean prior to adding
new material (see Chapter 11.3.5).
5. Screw the new recoat bottle into place and replace
the front panel and the four (4) socket head cap
screws.
6. Ensure the Handset Controller is connected to the
unit.
7. Turn on power to the device and wait for the
system to initialize.
8. Execute five (5) Purge cycles (Tools: Purge on
Handset Controller). Each Purge cycle will draw
100 microliters of recoat material from the bottom
of the recoat bottle through the red Fill Tube and
inject material back into the top of the recoat bottle
through the green Purge Tube (see Figure 35).
Five (5) Purge cycles are required to fill the pump
with recoat material and force any air out of the pump system. This will take approximately 15 minutes to
complete.
