WARNING: Allow only qualified personnel to perform the
following tasks. Follow the safety instructions in this document
and all other related documentation.
See Figure 1.
The 2K swirl nozzle attachments mount to the Two Component
dispensing gun to provide a thoroughly mixed, temperature-conditioned
material stream in a swirl-type pattern. The 2K pneumatic swirl nozzle
attachments include the following assemblies:
STemperature conditioning mounting assembly (1)
SConditioning block assembly (2)
SMixer assembly (3)

The temperature conditioning mounting assembly receives air from the
mixer assembly and water from the conditioning block. The assembly
mounts to a robot or stationary dispensing gun mounting bracket.
The conditioning block assembly mounts to the mixer tube housing. A
constant stream of water through the conditioning blocks keeps the
dispensing material at a constant temperature. A toggle latch clamps the
assembly to the mixer tube housing.
The mixer assembly mounts to the tip of the 2K dispensing gun. A
stream of air from the bores in the air nozzle adapter hits the material
stream from the static mixer nozzle, causing the steady material stream
to swirl.
Perform these steps to install the pre-assembled attachments and
tubings and fittings to your existing 2K dispensing gun.
See Figure 2.
1. Transfer the hole pattern from the insulator (1) to your robot or
stationary dispensing gun mounting bracket.
2. Drill or tap the holes according to your specific mounting
requirements.
3. Line up the insulator, manifold (3), and bracket (4).
4. Install two customer-supplied bolts and washers (5, 6). The holes will
accommodate either 1/4-in. or M6 bolts.
NOTE: Use threadlocking adhesive on the jam nut.
5. Tighten the bulkhead connector (7) to the bracket.
6. Install the quick disconnect coupling and fittings (8) to the bulkhead
connector.
7. Install the mixer assembly (14) onto the tip of the 2K dispensing gun.
8. Attach the elbow (12) to the air nozzle collar (13).
9. Open the hinged conditioning blocks on the temperature conditioning
mounting assembly (15) and attach them to the mixer tube housing.
10. Engage and close the toggle latch.
